     DETAILED DESCRIPTION OF THE INVENTION 
     Silk Fibroin-Based Protein Fragments and Solutions Thereof 
     Provided herein are methods for producing pure and highly scalable silk protein fragment (SPF) mixture solutions that may be used to coat at least a portion of textiles or may be formed into usable fibers for weaving into yarn. In some embodiments, SPF mixture solutions may also refer to silk fibroin solutions (SFS), and vice versa. The solutions are generated from raw pure intact silk protein material and processed in order to remove any sericin and achieve the desired weight average molecular weight (MW) and polydispersity of the fragment mixture. Select method parameters may be altered to achieve distinct final silk protein fragment characteristics depending upon the intended use. The resulting final fragment solution is pure silk protein fragments and water with PPM to non-detectable levels of process contaminants. The concentration, size and polydispersity of silk protein fragments in the solution may further be altered depending upon the desired use and performance requirements. In an embodiment, the pure silk fibroin-based protein fragments in the solution are substantially devoid of sericin, have an average weight average molecular weight ranging from about 1 kDa to about 350 kDa, and have a polydispersity ranging from about 1.0 and about 5.0. In an embodiment, the pure silk fibroin-based protein fragments in the solution are substantially devoid of sericin, have an average weight average molecular weight ranging from about 6 kDa to about 17 kDa, and have a polydispersity ranging from about 1.5 and about 3.0, or from about 1.0 and about 5.0. In an embodiment, the pure silk fibroin-based protein fragments in the solution are substantially devoid of sericin, have an average weight average molecular weight ranging from about 17 kDa to about 39 kDa, and have a polydispersity ranging from about 1.5 and about 3.0, or from about 1.0 and about 5.0. In an embodiment, the pure silk fibroin-based protein fragments in the solution are substantially devoid of sericin, have an average weight average molecular weight ranging from about 39 kDa to about 80 kDa, and have a polydispersity ranging from about 1.5 and about 3.0, or from about 1.0 and about 5.0. In an embodiment, the solutions may be used to generate articles, such as silk gels of varying gel and liquid consistencies by varying water content/concentration, or sold as a raw ingredient into the consumer market. As used herein, the term “silk solution” may refer to solutions of silk proteins, including solutions of silk fibroin-based protein fragments. Methods of making silk fibroin-based protein fragments and solutions thereof are described for example in U.S. Pat. Nos. 9,187,538, 9,511,012, 9,517,191, 9,522,107, 9,522,108, and 9,545,369.

     Processes for Production of Silk Fibroin-Based Protein Fragments and Solutions Thereof 
     As used herein, the term “fibroin” includes silkworm fibroin and insect or spider silk protein. In an embodiment, fibroin is obtained from  Bombyx mori . In an embodiment, the spider silk protein is selected from the group consisting of swathing silk (Achniform gland silk), egg sac silk (Cylindriform gland silk), egg case silk (Tubuliform silk), non-sticky dragline silk (Ampullate gland silk), attaching thread silk (Pyriform gland silk), sticky silk core fibers (Flagelliform gland silk), and sticky silk outer fibers (Aggregate gland silk). 
     A silk fragment-water solution of the present disclosure can be sterilized following standard methods in the art not limited to filtration, heat, radiation or e-beam. It is anticipated that the silk protein fragment mixture, because of its shorter protein polymer length, will withstand sterilization better than intact silk protein solutions described in the art. Additionally, silk articles created from the SPF mixtures described herein may be sterilized as appropriate to application. 
     In an embodiment, the above-described SPF mixture solutions may be utilized to coat at least a portion of a fabric which can be used to create a textile. In an embodiment, the above-described SPF mixture solutions may be weaved into yarn that can be used as a fabric in a textile. 
     Methods and processes for making silk fibroin-based protein fragments and solutions thereof are generally described by U.S. Pat. Nos. 9,187,538, 9,522,107, 9,517,191, 9,522,108, 9,511,012, and 9,545,369, U.S. Patent Application Publications Nos. 20160022559, 20150094269, 20160222579, and 20160281294, and International Patent Application Publications Nos. WO 2015048805 and WO 2016090055, the entirety of each are incorporated herein by reference. Briefly, heat-treated or non-heat-treated silk worm cocoons, silk fibers, silk powder, or spider silk can be used as the silk source. If starting from raw silk cocoons from  Bombyx mori , the cocoons can be cut into small pieces. The raw silk is then extracted and rinsed to remove any sericin, which results in substantially sericin free raw silk. In an embodiment, water is heated, and a salt is added, for example a carbonate. The raw silk is added to the boiling water/salt, and submerged for a period of time. In some embodiments, boiling for a longer time results in smaller silk protein fragments. Subsequently, the solution is drained, and excess water/salt is removed from the silk fibroin fibers (e.g., ring out the fibroin extract by hand, spin cycle using a machine, etc.). The resulting silk fibroin extract is rinsed with warm to hot water to remove any remaining adsorbed sericin or contaminate. The resulting silk fibroin extract is a substantially sericin-depleted silk fibroin. In some embodiments, it may be advantageous to agitate, turn or circulate the rinse water to maximize the rinse effect. After rinsing, excess water is removed from the extracted silk fibroin fibers (e.g., ring out fibroin extract by hand or using a machine). Alternatively, methods known to one skilled in the art such as pressure, temperature, or other reagents or combinations thereof may be used for the purpose of sericin extraction. The extracted fibroin fibers are then allowed to dry. Once dry, the extracted silk fibroin is dissolved using a solvent added to the silk fibroin at a temperature between ambient and boiling. In an embodiment, the solvent is a solution of a different salt. Alternatively, the extracted fibroin fibers are not dried but wet and placed in the solvent; solvent concentration can then be varied to achieve similar concentrations as to when adding dried silk to the solvent. Complete dissolution of the extracted fibroin fibers can be achieved by varying the treatment time and temperature along with the concentration of dissolving solvent. To ensure complete dissolution, the silk fibers should be fully immersed within the already heated solvent solution and then maintained at various temperatures. The temperature at which the silk fibroin extract is added to the salt solution (or vice versa) has an effect on the time required to completely dissolve the fibroin and on the resulting molecular weight and polydispersity of the final SPF mixture solution. In addition, agitation during introduction or dissolution may be used to facilitate dissolution at varying temperatures and concentrations. Alternatively, whole cocoons may be placed directly into a solvent, bypassing extraction. This requires subsequent filtration of silk worm particles from the silk and solvent solution and sericin removal using methods know in the art for separating hydrophobic and hydrophilic proteins such as a column separation and/or chromatography, ion exchange, chemical precipitation with salt and/or pH, and or enzymatic digestion and filtration or extraction, all methods are common examples and without limitation for standard protein separation methods. Non-heat treated cocoons with the silkworm removed, may alternatively be placed into a solvent, bypassing extraction. The methods described above may be used for sericin separation, with the advantage that non-heat treated cocoons will contain significantly less worm debris. Dialysis may be used to remove the dissolution solvent from the resulting dissolved fibroin protein fragment solution by dialyzing the solution against a volume of water. Pre-filtration prior to dialysis is helpful to remove any debris (i.e., silk worm remnants) from the silk and salt solution. The result of dissolution at the desired time and temperate filtration is a generally translucent particle-free room temperature shelf-stable silk protein fragment-salt solution. After dialysis, the final silk solution may be further filtered to remove any remaining debris (i.e., silk worm remnants). Alternatively, Tangential Flow Filtration (TFF), which is a rapid and efficient method for the separation and purification of biomolecules, may be used to remove the solvent from the resulting dissolved fibroin solution. TFF offers a highly pure aqueous silk protein fragment solution and enables scalability of the process in order to produce large volumes of the solution in a controlled and repeatable manner.

     In some embodiments, SFS may be applied to fabric having a coefficient of friction of greater than about 0.04, or greater than about 0.05, or greater than about 0.06, or greater than about 0.07, or greater than about 0.08, or greater than about 0.09, or greater than about 0.10, or greater than about 0.10, or greater than about 0.15, or greater than about 0.20, or greater than about 0.25, or greater than about 0.30, or greater than about 0.35, or greater than about 0.40, or greater than about 0.45, or greater than about 0.50, or greater than about 0.55, or greater than about 0.60, or greater than about 0.65, or greater than about 0.70, or greater than about 0.75, or greater than about 0.80, or greater than about 0.85, or greater than about 0.90, or greater than about 0.95, or greater than about 1.00, or greater than about 1.05. 
     In some embodiments, chemical finishes may be applied to textiles before or after such textiles are coated with SFS. In an embodiment, chemical finishing may be intended as the application of chemical agents and/or SFS to textiles, including fibers, yarn, and fabric, or to garments that are prepared by such fibers, yarn, and fabric to modify the original textile&#39;s or garment&#39;s properties and achieve properties in the textile or garment that would be otherwise absent. With chemical finishes, textiles treated with such chemical finishes may act as surface treatments and/or the treatments may modify the elemental analysis of treated textile base polymers. 
     In an embodiment, a type of chemical finishing may include the application of certain silk-fibroin based solutions to textiles. For example, SFS may be applied to a fabric after it is dyed, but there are also scenarios that may require the application of SFS during processing, during dyeing, or after a garment is assembled from a selected textile or fabric, thread, or yarn. In some embodiments, after its application, SFS may be dried with the use of heat. SFS may then be fixed to the surface of the textile in a processing step called curing. 
     In some embodiments, SFS may be supplied in a concentrated form suspended in water. In some embodiments, SFS may have a concentration by weight (% w/w or % w/v) or by volume (v/v) of less than about 50%, or less than about 45%, or less than about 40%, or less than about 35%, or less than about 30%, or less than about 25%, or less than about 20%, or less than about 15%, or less than about 10%, or less than about 5%, or less than about 4%, or less than about 3%, or less than about 2%, or less than about 1%, or less than about 0.1%, or less than about 0.01%, or less than about 0.001%, or less than about 0.0001%, or less than about 0.00001%. In some embodiments, SFS may have a concentration by weight (% w/w or % w/v) or by volume (v/v) of greater than about 50%, or greater than about 45%, or greater than about 40%, or greater than about 35%, or greater than about 30%, or greater than about 25%, or greater than about 20%, or greater than about 15%, or greater than about 10%, or greater than about 5%, or greater than about 4%, or greater than about 3%, or greater than about 2%, or greater than about 1%, or greater than about 0.1%, or greater than about 0.01%, or greater than about 0.001%, or greater than about 0.0001%, or greater than about 0.00001%. 
     In some embodiments, the solution concentration and the wet pick of the material determines the amount of silk fibroin solution (SFS), which may include silk-based proteins or fragments thereof, that may be fixed or otherwise adhered to the textile being coated. The wet pick up may be expressed by the following formula:

     Regarding methods for applying SFS to textiles more broadly, SFS may be applied to textiles through a pad or roller application on process, a saturation and removal process, and/or a topical application process. Moreover, the methods of silk application (i.e., SFS application or coating) may include bath coating, kiss rolling, spray coating, and/or two-sided rolling. In some embodiments, the coating processes (e.g., bath coating, kiss rolling, spray coating, two-sided rolling, roller application, saturation and removal application, and/or topical application), drying processes, and curing processes may be varied as described herein to modify one or more selected textile (e.g., fabric) properties of the resulting coated textile wherein such properties include, but are not limited to wetting time, absorption rate, spreading speed, accumulative one-way transport, and/or overall moisture management capability. In some embodiments, the aforementioned selected properties may be enhanced by varying one or more of the coating processes, drying processes, and curing processes as described herein. 
     In some embodiments, the silk compositions provided herein may be applied in a wet process or a dry process, such as by applying the silk compositions to a wet textile or a dry textile. 
     In an embodiment, the padder application may be used on dry or wet textile. For example, it may be applied on fabric after the dyeing process. The fabric may be fed into a water bath solution and may reach saturation. The fabric to be coated may then pass through a set of rollers that, based on multiple variables, extract the bath solution in excess to the desired wet pick up %. The variables that affect the wet pick up % are the roller pressure and materials, the fabric composition and construction, and the SFS viscosity. An exemplary padder roller configuration is shown in  FIG. 183 . 
     In an embodiment, the padder application on wet textile may be used to reduce the cost of drying the fabric post dyeing. The fabric exiting the pad rollers may maintain a higher weight % than the incoming fabric to maintain a SFS deposit on the fabric; and the SFS solution may need to account for any dilution taking place due to water present on the incoming fabric. 
     In an embodiment, the saturation and removal application is a low wet pick up method that may, for example, solve some of the issues associated with removing large amounts of water during drying processes. Since fabric may dry in an oven from the outside surface towards the inside, water may move from the inside to the outside resulting in a higher coating concentration on the outside surface. With less water content, migration may be reduced due to a higher viscosity in the solution. However, decreased wet pick up may result in an uneven solution deposit. 
     In an embodiment, vacuum extraction may be used as a method for low wet pick up. Saturated fabric may be subject to a vacuum that pulls solution out of the fabric and returns it to an application loop. Air jet ejection may be a method for providing low wet pick up. The saturated fabric may be subjected to high pressure steam that removes solution out of the fabric and returns it to an application loop. 
     In an embodiment, a porous bowl method may be used for low wet pick up. Solid pad rollers may be substituted with rubber coated fiber rollers. Saturated fabric may be subjected to the pressure of the roller since the porosity of the rollers may allow for more solution to be squeezed from the fabric. 
     In an embodiment, a transfer padding method may be used for low wet pick up. Saturated fabric may be passed through two continuous dry non-woven fabrics and may be pressed at low pressure. The non-woven fabrics may extract excess solution from the fabric being treated. 
     In an embodiment, topical application may be used as a low wet pick up method of application that deposits the desired amount of SFS to the fabric without removing any excess material. The methods described above may be used for one-sided coating applications, but there are variations that may allow for two-sided coating. 
     In an embodiment, kiss rolling may be used as a topical method of application that transfers the SFS from a roller (i.e., a kiss roller) to one side of the fabric. The solution viscosity, roller surface finish, speed of the roller, speed of the fabric, contact angle of the fabric on the roller and properties of the fabric are parameters that control the amount of solution deposited on the fabric. An exemplary kiss roller is depicted in  FIG. 184 . 
     In an embodiment, a variation to the kiss roller technique may be the Triatex MA system that uses two moisture content sensors to determine the solution pick up at the kiss roller and adjust the kiss roller controllable variable to maintain consistent the solution deposit onto the fabric. 
     In an embodiment, a loop transfer application may be used as a topical method of application that transfers the SFS from a saturated loop fabric to the fabric to be coated between low pressure pad rollers. There is a two rollers version that may allow for minimum contact with the fabric and a three rollers version that allows for greater contact with the fabric. 
     In an embodiment, an engrave roller application may be used as a topical method of application that may transfer a metered amount of SFS onto the fabric. This may be achieved by engraving a pattern on the surface of the roller with precise depth and design that contains a controlled amount of SFS. A blade may be used to remove any solution that is deposited on the surface of the roller in order to maintain a consistent transfer of solution to the fabric to be coated. 
     In an embodiment, rotary screen printing may be used as a topical method of application that may deposit SFS onto the fabric by seeping the solution through a roller screen. The solution may be contained in the screen print roller core at a set level while a blade may be used to remove any excess solution from the interior roller wall, providing a clean surface for the next revolution of the screen printer roller. 
     In an embodiment, magnetic roller coating may be used as a topical method of application that may deposit SFS from a kiss roller onto the fabric to be coated. The kiss roller is semi-submersed in a bath solution while a magnetic field created in the fabric driving roller determines the amount of pressure applied by the kiss roller, controlling the solution pick up rate. 
     In an embodiment, spraying may be used as a topical method of application that may transfer SFS onto the fabric by nebulizing the solution. The spray pattern may be controlled by the nozzle pattern, size, and the air flow. Spray application may be used for one side application or also two sided applications. 
     In an embodiment, foam application may be used a topical method of application that may transfer SFS onto the fabric. Foam may be made by substituting part of the water in the solution with air therefore reducing the amount of water to be applied to the fabric. Foam application may be used for one-sided application or two-sided application where the same foam may be deposited through a squeeze roller or different foam solutions may be provided through transfer rolls or through a slot applicator. 
     In an embodiment, the application of SFS may take place after a garment is assembled. In an embodiment, the process may take place in a washing and dyeing machine or in a spray booth. For example, a washing and dyeing machine may be similar in shape to a household front loader washing machine, it allows the process to take place at exhaustion post dyeing or with an independent processing cycle. In an embodiment, a spray booth machine may include a manual or a fully automated process. For example, a garment may be held by a mannequin while an operator or an anthropomorphic robot may spray the solution onto the fabric. 
     In an embodiment, SFS may be a water based solution that, after its application to the textile, may require thermal vaporization to infuse the SFS onto the textile. Thermal vaporization may be applied by heat transfer through radiation with equipment such as infrared or radio frequency dryer. 
     In an embodiment, thermal vaporization may be applied by convection through heated air circulating in an oven to the required temperature, while the fabric is clamped and is transported by a conveyor. This allows full control on fabric width dimension. 
     In an embodiment, thermal vaporization may be applied by conduction through contacting the textile with heated cylinder or calendar cylinder. Since the fabric is not clamp there is minimal control on fabric width. 
     In an embodiment, curing of the SFS on the textile may be completed with the same equipment used for the thermal vaporization in a continuous cycle or in a separate cycle. 
     In an embodiment, curing time temperature may be dependent the textile polymer content and the binding method of preference for the SFS with the specific polymer. The curing process may not start until the thermal vaporization is completed. 
     In some embodiments, sensor may be used to monitor SFS deposition on the textile and the drying and curing steps. 
     In some embodiments, for monitoring the deposition of SFS, a contactless sensor, like the one supplied by Pleva model AF120 based on microwave absorption of water, may be used. Measurement of the material moisture may be based on microwave absorption by water. A semiconductor oscillator transmits microwave energy through the web. The non-absorbed part of the energy may be received on the opposite side by a microwave receiver. The amount of absorption is a measurement of the absolute moisture content. The microwave sensor is capable of detecting and measuring water content from a minimum of 0 up to 2000 g H 2 O/m 2 . 
     In some embodiments, for wide fabric processing multiple sensor may be paired side by side, delivering the data analysis to a centralized control system loop capable to add more solution in the area of the fabric that is low. 
     In some embodiments, another sensor may be used that is based on microwave technology, such as Aqualot by Mahlo. The sensor may evaluate the shift in the resonant frequency of the two standing waves with respect to each other rather than the attenuation of the microwaves by the quantity of water molecules in the measuring gap. 
     In some embodiments, another contactless sensor for SFS may be the IR-3000 by MoistTech based on near infrared sensing technology. The sensor measures the amount of near infrared energy reflected at a given wavelength that is inversely proportional to the quantity of absorbing molecules in the fabric. 
     In some embodiments, the residual moister at the end of the curing process may be measured to further confirm the drying and curing process. In addition to the above sensor, a contact sensor such as the Textometer RMS by Mahlo may be used for measuring moister through conductivity. 
     In some embodiments, monitoring the end of the drying process phase may be achieved by measuring the fabric temperature with a contactless temperature sensor. When wet product enters the dryer, it first heats up to the cooling limit temperature. In some embodiments, when the water content drops to residual moisture levels, the product temperature may begin to rise again. The closer the product temperature approaches the circulation air temperature in the dryer, the slower the temperature continues to rise. In some embodiments, at a certain temperature threshold (called the fixing temperature) the temperature necessary for processing, fixing, or condensing is reached. 
     In some embodiments, to determine the dwell time for a desired product temperature, the surface temperature of the product may be measured without contact at several locations in the dryer using high-temperature resistant infrared pyrometers. Mahlo Permaset VMT is an infrarem Pyrometer that may be assembled in multiple units to monitors temperature through the dryer. Setex is another manufacturer offering fabric temperature sensors for use in dryers and oven like the models WTM V11, V21, and V41. 
     In some embodiments, SFS may be applied to a textile during exhaust dyeing. In some embodiments, the process may involve loading fabric into a bath, originally known as a batch, and allowing it to come into equilibrium with the solution. Exhaust dyeing may be the ability of the silk fibroin molecules to move from the solution onto the fibers or thread of a textile (substantivity). The substantivity of the silk fibroin may be influenced by temperature or additives, such as salt. 
     In some embodiments, an exhaust dyeing process may take anywhere from a few minutes to a few hours. When the fabric has been absorbed, or fixed, as much silk fibroin as it can, the bath may be emptied and the fabric may be rinsed to remove any excess solution. 
     In some embodiments, an important parameter in exhaust dyeing may be what is known as the specific liquor ratio. This describes the ratio of the mass of the fabric to the volume of the SFS bath and determines the amount of silk fibroin deposited on a textile. 
     In some embodiments, SFS can be applied to a textile during jet dyeing processes. A jet dyeing machine may formed by closed tubular system where the fabric is placed. For transporting the fabric through the tube, a jet of dye liquor is supplied through a venturi. The jet may create turbulence. This may help in SFS penetration along with preventing the fabric from touching the walls of the tube. For example, as the fabric is often exposed to comparatively higher concentrations of liquor within the transport tube, a small SFS bath is needed in the bottom of the vessel. This arrangement may be enough for the smooth movement from rear to front of the vessel. 
     In some embodiments, SFS may be applied during Paddle dyeing. Paddle dyeing machines may be generally used to many forms of textiles but the method best suits to garments. Heat may be generated through steam injection directly into the coating bath. In an embodiment, a paddle dyeing machine operates through a paddle that circulates both the bath and garments in a perforated central island. It is here that the SFS, water, and steam for heat are added. The overhead paddle machine may be described as a vat with a paddle that has blades of full width. The blades may generally dip a few centimeters into the vat. This action may stir the bath and push garments to be died down, thus keeping them submerged in the dye liquor. 
     In some embodiments, the processing methods set forth herein may be used to apply SFS to textiles with one or more of the following parameters including, but not limited to, fabric speed, solution viscosity, solution added to fabric, fabric range width, drying temperature, drying time, curing time, fabric tension, padder pressure, padder roller shore hardness, stenter temperature, and common drying and curing temperatures. In an embodiment, the processing method parameters may also include a condensation temperature, which may vary depending upon the chemical recipe used to apply the SFS to the textiles.

     In some embodiments, the chemical agent may include an acidic agent. Accordingly, in some embodiments, SFS may include an acidic agent. In some embodiments, an acidic agent may be a Bronsted acid. In an embodiment, the acidic agent includes one or more of citric acid and acetic acid. In an embodiment, the acidic agent aids the deposition and coating of SPF mixtures (i.e., SFS coating) on the textile to be coated as compared to the absence of such acidic agent. In an embodiment, the acidic agent improves crystallization of the SPF mixtures at the textile to be coated. 
     In an embodiment, the acidic agent is added at a concentration by weight (% w/w or % w/v) or by volume (v/v) of greater than about 0.001%, or greater than about 0.002%, or greater than about 0.003%, or greater than about 0.004%, or greater than about 0.005%, or greater than about 0.006%, or greater than about 0.007%, or greater than about 0.008%, or greater than about 0.009%, or greater than about 0.01%, or greater than about 0.02%, or greater than about 0.03%, or greater than about 0.04%, or greater than about 0.05%, or greater than about 0.06%, or greater than about 0.07%, or greater than about 0.08%, or greater than about 0.09%, or greater than about 0.1%, or greater than about 0.2%, or greater than about 0.3%, or greater than about 0.4%, or greater than about 0.5%, or greater than about 0.6%, or greater than about 0.7%, or greater than about 0.8%, or greater than about 0.9%, or greater than about 1.0% or greater than about 2.0%, or greater than about 3.0%, or greater than about 4.0%, or greater than about 5.0%. 
     In an embodiment, the acidic agent is added at a concentration by weight (% w/w or % w/v) or by volume (v/v) of less than about 0.001%, or less than about 0.002%, or less than about 0.003%, or less than about 0.004%, or less than about 0.005%, or less than about 0.006%, or less than about 0.007%, or less than about 0.008%, or less than about 0.009%, or less than about 0.01%, or less than about 0.02%, or less than about 0.03%, or less than about 0.04%, or less than about 0.05%, or less than about 0.06%, or less than about 0.07%, or less than about 0.08%, or less than about 0.09%, or less than about 0.1%, or less than about 0.2%, or less than about 0.3%, or less than about 0.4%, or less than about 0.5%, or less than about 0.6%, or less than about 0.7%, or less than about 0.8%, or less than about 0.9%, or less than about 1.0% or less than about 2.0%, or less than about 3.0%, or less than about 4.0%, or less than about 5.0%. 
     In an embodiment, the chemical agent may include silicone. In some embodiments, a SFS may include silicone. In some embodiments, silicone may include a silicone emulsion. The term “silicone,” may generally refer to a broad family of synthetic polymers, mixtures of polymers, and/or emulsions thereof, that have a repeating silicon-oxygen backbone including, but not limited to, polysiloxanes. For example, a silicone may include ULTRATEX® CSP, which is a commercially available (Huntsman International LLC) silicone emulsion that may be used as a softening agent and which may also increase fabric resilience, elasticity of knitted fabrics, and fiber lubrication and also improve sewability. A silicone may also include ULTRATEX® CI, which is a commercially available silicone composition (Huntsman International LLC) that may be used as a fabric softening agent. In some embodiments, a silicone may include any silicone species disclosed herein. 
     Describing the compositions and coatings more broadly, silicone may be used, for example to improve fabric hand, but may also increase the water repellency (or reduce water transport properties) of a fabric coated with silicone. Silicone may be used in combination with SFS to counteract the water repellant (water transport) properties of silicone. 
     In some embodiments, SFS may include silicone in a concentration by weight (% w/w or % w/v) or by volume (v/v) of less than about 25%, or less than about 20%, or less than about 15%, or less than about 10%, or less than about 9%, or less than about 8%, or less than about 7%, or less than about 6%, or less than about 5%, or less than about 4%, or less than about 3%, or less than about 2%, or less than about 1%, or less than about 0.9%, or less than about 0.8%, or less than about 0.7%, or less than about 0.6%, or less than about 0.5%, or less than about 0.4%, or less than about 0.3%, or less than about 0.2%, or less than about 0.1%, or less than about 0.01%, or less than about 0.001%. 
     In some embodiments, SFS may include silicone in a concentration by weight (% w/w or % w/v) or by volume (v/v) of greater than about 25%, or greater than about 20%, or greater than about 15%, or greater than about 10%, or greater than about 9%, or greater than about 8%, or greater than about 7%, or greater than about 6%, or greater than about 5%, or greater than about 4%, or greater than about 3%, or greater than about 2%, or greater than about 1%, or greater than about 0.9%, or greater than about 0.8%, or greater than about 0.7%, or greater than about 0.6%, or greater than about 0.5%, or greater than about 0.4%, or greater than about 0.3%, or greater than about 0.2%, or greater than about 0.1%, or greater than about 0.01%, or greater than about 0.001%. 
     In some embodiments, SFS may be supplied in a concentrated form suspended in water. In some embodiments, SFS may have a pH of less than about 9, or less than about 8. In some embodiments, SFS may have a concentration by weight (% w/w or % w/v) or by volume (v/v) of less than about 50%, or less than about 45%, or less than about 40%, or less than about 35%, or less than about 30%, or less than about 25%, or less than about 20%, or less than about 15%, or less than about 10%, or less than about 5%, or less than about 4%, or less than about 3%, or less than about 2%, or less than about 1%, or less than about 0.1%, or less than about 0.01%, or less than about 0.001%, or less than about 0.0001%, or less than about 0.00001%. In some embodiments, SFS may have a concentration by weight (% w/w or % w/v) or by volume (v/v) of greater than about 50%, or greater than about 45%, or greater than about 40%, or greater than about 35%, or greater than about 30%, or greater than about 25%, or greater than about 20%, or greater than about 15%, or greater than about 10%, or greater than about 5%, or greater than about 4%, or greater than about 3%, or greater than about 2%, or greater than about 1%, or greater than about 0.1%, or greater than about 0.01%, or greater than about 0.001%, or greater than about 0.0001%, or greater than about 0.00001%. 
     In some embodiments, SFS may include an acidic agent, and may have a pH of less than about 9, or less than about 8.5, or less than about 8, or less than about 7.5, or less than about 7, or less than about 6.5, or less than about 6, or less than about 5.5, or less than about 5, or less than about 4.5, or less than about 4, or greater than about 3.5, or greater than about 4, or greater than about 4.5, or greater than about 5, or greater than about 5.5, or greater than about 6, or greater than about 6.5, or greater than about 7, or greater than about 7.5, or greater than about 8, or greater than about 8.5. 
     In some embodiments, an SFS coating may include SFS, as described herein. In some embodiments, SFS may include a silicone and/or an acidic agent. In some embodiments, SFS may include a silicone and an acidic agent. In some embodiments, the SFS may include a silicone, an acidic agent, and/or an additional chemical agent, wherein the additional chemical agent may be one or more of the chemical agents described herein. In some embodiments, SFS may include a silicone emulsion and an acidic agent, such as acetic acid or citric acid. 
     In some embodiments, the coating processes of the invention may include a finishing step for the resulting coated textiles. In some embodiments, the finishing or final finishing of the textiles (e.g., fabrics) that are coated with SFS under the processes of the invention may include sueding, steaming, brushing, polishing, compacting, raising, tigering, shearing, heatsetting, waxing, air jet, calendaring, pressing, shrinking, treatment with polymerizer, coating, lamination, and/or laser etching. In some embodiments, finishing of the SFS coated textiles may include treatment of the textiles with an AIRO® 24 dryer that may be used for continuous and open-width tumbling treatments of woven, non-woven, and knitted fabrics. 
     In some embodiments, a coated textile (e.g., a fabric) may be prepared by unrolling a fabric roll ( FIG. 185 ) to prepare a piece of fabric. The perimeter of such fabric may be processed. For example, fabric ( FIG. 186 ) may have dimensions of 35 cm×35 cm (13.5 inch×13.5 inch) with a tolerance of +/−1 cm (+/−0.4 inch). In some embodiments, every fabric sample may be massed on analytical balance by folding the fabric sample multiple times until it may be contained by a weighing boat on a balance. Each measurement may be recorded. In some embodiments, a coating process may be initiated by preparing a curing oven by setting a selected temperature therein. A padder laboratory unit may be turned on and the speed of said padder unit may be set to a selected velocity and the roller pressure may be adjusted to a selected pressure by operating a cam lever system and locking it in place once the desired pressure is achieved. A silk solution (i.e., SFS) may be poured into a bath (e.g., a stainless steel bath) ( FIG. 187 ). After a fabric sample is submerged in the bath, it may be allowed to reach saturation, and the fabric sample may then be removed from the bath and laid between two rollers of the padder unit ( FIG. 188 ). The fabric sample as it is transported through the rollers it may be squeezed of excessive fluid as determined by the rollers&#39; pressure. The fabric sample may then exit to the opposite side of the rollers. The resulting fabric sample may then be placed on top of the curing frame and may then be gently pushed one edge at a time to engage the fabric edges with frame pins (see  FIGS. 189 and 190 ). The frame may be placed in the drying and curing oven, with the door of said oven secured and kept closed for the drying and curing time ( FIG. 191 ). A timer may be started to alert when the drying and curing time has elapsed. When the timer signals completion of the curing process, the oven door is opened and a temperature sensor (e.g., an IR temperature sensor) may be used to measure the fabric sample surface temperature. The frame bearing the fabric sample may then be removed from the oven and placed on a cooling rack ( FIG. 192 ). The sample fabric may then be removed from the frame and weighed. 
     In some embodiments, the SFS coated textiles (e.g., fabrics) described herein may meet or exceed requirements established by the following Test Methods:

     EXAMPLES 
     The following examples are put forth so as to provide those of ordinary skill in the art with a complete disclosure and description of how to make and use the described embodiments, and are not intended to limit the scope of what the inventors regard as their invention nor are they intended to represent that the experiments below are all or the only experiments performed. Efforts have been made to ensure accuracy with respect to numbers used (e.g., amounts, temperature, etc.) but some experimental errors and deviations should be accounted for. Unless indicated otherwise, parts are parts by weight, molecular weight is weight average molecular weight, temperature is in degrees Centigrade, and pressure is at or near atmospheric. 
     Materials and Methods 
     A) Silk Molecular Weight Determination 
     The following equipment and material are used in determination of Silk Molecular weight: Agilent 1100 with chemstation software ver. 10.01; Refractive Index Detector (RID); analytical balance; volumetric flasks (1000 mL, 10 mL and 5 mL); HPLC grade water; ACS grade sodium chloride; ACS grade sodium phosphate dibasic heptahydrate; phosphoric acid; dextran MW Standards-Nominal Molecular Weights of 5 kDa, 11.6 kDa, 23.8 kDa, 48.6 kDa, and 148 kDa; 50 mL PET or polypropylene disposable centrifuge tubes; graduated pipettes; amber glass HPLC vials with Teflon caps; Phenomenex PolySep GFC P-4000 column (size: 7.8 mm×300 mm). 
     Procedure: 
     I) Preparation of 1 L Mobile Phase (0.1 M Sodium Chloride Solution in 0.0125 M Sodium Phosphate Buffer) 
     Take a 250 mL clean and dry beaker, place it on the balance and tare the weight. Add about 3.3509 g of sodium phosphate dibasic heptahydrate to the beaker. Note down the exact weight of sodium phosphate dibasic weighed. Dissolve the weighed sodium phosphate by adding 100 mL of HPLC water into the beaker. Take care not to spill any of the content of the beaker. Transfer the solution carefully into a clean and dry 1000 mL volumetric flask. Rinse the beaker and transfer the rinse into the volumetric flask. Repeat the rinse 4-5 times. In a separate clean and dry 250 mL beaker weigh exactly about 5.8440 g of sodium chloride. Dissolve the weighed sodium chloride in 50 mL of water and transfer the solution to the sodium phosphate solution in the volumetric flask. Rinse the beaker and transfer the rinse into the volumetric flask. Adjust the pH of the solution to 7.0±0.2 with phosphoric acid. Make up the volume in volumetric flask with HPLC water to 1000 mL and shake it vigorously to homogeneously mix the solution. Filter the solution through 0.45 μm polyamide membrane filter. Transfer the solution to a clean and dry solvent bottle and label the bottle. The volume of the solution can be varied to the requirement by correspondingly varying the amount of sodium phosphate dibasic heptahydrate and sodium chloride. 
     II) Preparation of Dextran Molecular Weight Standard Solutions 
     At least five different molecular weight standards are used for each batch of samples that are run so that the expected value of the sample to be tested is bracketed by the value of the standard used. Label six 20 mL scintillation glass vials respective to the molecular weight standards. Weigh accurately about 5 mg of each of dextran molecular weight standards and record the weights. Dissolve the dextran molecular weight standards in 5 mL of mobile phase to make a 1 mg/mL standard solution. 
     III) Preparation of Sample Solutions 
     When preparing sample solutions, if there are limitations on how much sample is available, the preparations may be scaled as long as the ratios are maintained. Depending on sample type and silk protein content in sample weigh enough sample in a 50 mL disposable centrifuge tube on an analytical balance to make a 1 mg/mL sample solution for analysis. Dissolve the sample in equivalent volume of mobile phase make a 1 mg/mL solution. Tightly cap the tubes and mix the samples (in solution). Leave the sample solution for 30 minutes at room temperature. Gently mix the sample solution again for 1 minute and centrifuge at 4000 RPM for 10 minutes. 
     IV) HPLC Analysis of the Samples 
     Transfer 1.0 mL of all the standards and sample solutions into individual HPLC vials. Inject the molecular weight standards (one injection each) and each sample in duplicate. Analyze all the standards and sample solutions using the following HPLC conditions: 
                                                Column   PolySep GFC P-4000 (7.8 × 300 mm)                                 Column Temperature   25°    C.

V) Data Analysis and Calculations—Calculation of Average Molecular Weight Using Cirrus Software
 
     Upload the chromatography data files of the standards and the analytical samples into Cirrus SEC data collection and molecular weight analysis software. Calculate the weight average molecular weight (M w ), number average molecular weight (M n ), peak average molecular weight (M p ), and polydispersity for each injection of the sample. Average the results for duplicate injections for each sample (Table 1).

C) Synthetic Materials Coating Method
 
     The following equipment and material are used in coating experiments: medium molecular weight silk fragments solution at 6%; low molecular weight silk fragments solution at 6%; citric acid; Ultratex CSP (Huntsman); M Dohmen Domosil RWAF; Ultratex SI (Huntsman); permanent marker; fabric style #6606D2 nylon/spandex; fabric style #6608D2B polyester/spandex. 
     The coating processing includes two separate coating steps. Each coating step may be followed by a drying step. 
     First Coating Step: the total liquor solution prepared and individual ingredient quantities are prepared. The sequence for mixing includes: loading tap water in a mixing tank; adding citric acid 50% in water, followed by mixing for 2-3 minutes; measuring and confirming that the pH is between 4-5; adding low molecular weight silk solution to the mixing tank, and mixing for 1-2 minutes; adding medium molecular weight silk solution to the mixing tank, and mixing for 1-2 minutes; transferring the liquor to the pad bath; processing the fabric with a pick-up rate of 35-70%, with a drying time as required by the fabric material and construction. 
     Second Coating Step: the total liquor solution prepared and individual ingredient quantities are prepared. The sequence for mixing includes: loading tap water in the mixing tank; adding citric acid 50% in water, and mixing for 2-3 minutes; measuring and confirming that the pH is between 4-5; adding silicone solution to the liquor, and mixing for 2-3 minutes; transferring the liquor to the pad bath; fabrics processed with the first coating step are processed through the frame; fabric is processed with a pick-up rate of 35-70% with a drying time as required by the fabric material and construction. 
     Example 1: Silk Coating Wool, Including a Citric Acid Pretreatment and Methanol Post Treatment—Water Drop Tested and Hand Evaluated 
     This experiment includes application of silk fibroin solution on wool fabrics after a pretreatment of citric acid and followed by a methanol bath (variables described in Table 3). The application takes place in a sequence of baths and pads application with multiple drying steps.

     Water drop test (Table 4) and hand evaluation (Tables 5 and 6) are used to characterize the fabrics, as follows:
         Samples are conditioned at ambient condition for 24 hrs;   A 7 cm diameter round metal hoop is inserted in the wool fabric tube and is placed on the drapability jig. A RODI water drop is dispensed with an eye dropper from approximately 3 cm above the fabric. A video imaging recording capture the time from the water drop contacting the fabric until its full absorption or up to 30 seconds;   The wool fabric tubes are scored for hand against a non treated control. Scoring are made from more softest to rougher and any additional perceived difference.

     Example 2: Silk Coating Wool, Including a Citric Acid Pretreatment and Methanol Post Treatment—Tested for Dimensional Changes after Laundering, Perceived Hand, and Fiber Morphology by SEM Analysis 
     Silk fibroin solution is applied on wool fabrics after a pretreatment of citric acid and, followed by a methanol bath (Table 7). The application takes place in a sequence of baths and pads application with multiple drying steps. The samples are tested for dimensional changes after laundering, perceived hand, and fiber morphology with SEM analysis (Tables 8-11).

     Samples are delivered to the MSC lab for dimensional changes post laundering analysis based on Woolmark Company TM31-May 2000 and AATCC Test Method 135-2015. Samples are tested after t=1 and t=4 laundering cycle for the Woolmark test and at t=0 and t=3 for the AATCC test. 
     After the dimensional analysis test, the wool fabric tubes are scored for hand against a non-treated control. Scoring are made for softness and any additional perceived difference. After the hand test is completed the samples are subjected to SEM analysis.

     Example 3: Silk Coating Wool, Including a Citric Acid Pretreatment and Methanol Post Treatment—Addition of a New Control; Samples Tested for Dimensional Changes after Laundering, Perceived Hand, and Fiber Morphology by SEM Analysis 
     This example adds a new control with no silk coating for evaluating the application of silk fibroin solution on fabrics made with wool fabric tube after a pretreatment of citric acid and followed by a methanol bath. The application takes place in a sequence of baths and pads application with multiple drying steps. The samples were tested for dimensional changes after laundering, perceived hand, and fiber morphology with SEM analysis.

             The dimensional changes of the samples post laundering are analyzed based on Woolmark Company TM31-May 2000 and AATCC Test Method 135-2015. Samples are tested after t=1 and t=4 laundering cycle for the Woolmark test, and at t=0 and t=3 for the AATCC test. 
             After the dimensional analysis test, the wool fabric tubes are scored for hand against a non treated control. Scoring are made for softness and any additional perceived difference. 
             After the hand test is completed the samples are analyzed by SEM ( FIGS. 7 to 14 ).

     Example 4: Silk Coating a Cashmere Fabric: Improving Pilling Resistance and Water Repellency 
     Materials and Methods: 
     A cashmere fabric was used to test for improvements in pilling resistance and water repellency upon silk treatment. The silk coated cashmere sample was obtained with a four bath process: 1) 0.25% Citric Acid; 2) 0.25% Citric Acid, 0.375% Low MW silk, 0.125% Med MW silk (Total Silk: 0.5% 3 L:1M); 3) 0.25% Citric Acid; 4) 80% Methanol.

     Analysis: Samples coated as described in Table 49, are conditioned at ambient for 24 hrs before delivering them to testing lab for laundering test. The samples are used for:
         N=1 control no laundering   N=1 after 10 laundering cycles   N=1 after 25 laundering cycles   N=1 after 50 laundering cycles   Fabrics are evaluated for hand by two technicians against the control not laundered (Table 50).       

     Laundering method AATCC Test Method 135-2015 (Table I, “Dimensional Changes of Fabrics after Home Laundering”). Testing Information: Home Laundered 52 times using AATCC TM 150 (Table II); Laundry Test Conditions: load size=1.8 kg (4 lbs), Launder Right Side Out Wash; Normal/CottonSturdy (III) 105±5° F. using 1993 AATCC Standard Reference Detergent WOB; Top Loading Machine; Tumble Dry (i) Cotton Sturdy; Ballast Wash Load Type 3-50/50 polyester/cotton bleached plain weave; Samples removed at 10, 25 and 52 launderings. 
     After laundering fabrics are evaluated for water drop test (Table 51). The sample fabric is placed on top of a 7 cm diameter positioned on the drapability jig. A RODI water drop is dispensed with an eye dropper from approximately 3 cm above the fabric. A video imaging recording capture the time from the water drop contacting the fabric until its full absorption or up to 60 seconds

     Analysis: 
     Samples coated as described in Table 52, are conditioned at ambient for 24 hrs before delivering them to testing lab for laundering test. The samples will be used for:
         N=1 control no laundering;   N=1 after 10 laundering cycles;   N=1 after 25 laundering cycles;   N=1 after 50 laundering cycles;   Fabrics are evaluated for hand by two technicians against the control not laundered (Table 53).       

     Laundering method AATCC Test Method 135-2015 (Table I, “Dimensional Changes of Fabrics after Home Laundering”). Testing Information: Home Laundered 52 times using AATCC TM 150 (Table II); Laundry Test Conditions: load size=1.8 kg (4 lbs), Launder Right Side Out Wash; (1) Normal/CottonSturdy (III) 105±5° F. using 1993 AATCC Standard Reference Detergent WOB; Top Loading Machine; Tumble Dry (i) Cotton Sturdy; Ballast Wash Load Type 3-50/50 polyester/cotton bleached plain weave; Samples removed at 10, 25 and 52 launderings. 
     After laundering fabrics are evaluated for water drop test (Table 54, and  FIG. 32 ). The sample fabric is placed on top of a 7 cm diameter positioned on the drapability jig. A RODI water drop is dispensed with an eye dropper from approximately 3 cm above the fabric. A video imaging recording capture the time from the water drop contacting the fabric until its full absorption or up to 60 seconds.

     Example 9: Nylon/Lycra and Polyester/Lycra Fabric Coated with Silk and Silicone: Evaluation of Textile Abrasion 
     The experiment includes the determination of the abrasion resistance of textile fabrics using the Martindale abrasion tester. Fabrics of all types may be tested by this method, but difficulties may arise with fabrics with a pile depth greater than 0.08 in (2 mm). 
     The values stated in inch-pound units are regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 
     Materials and Equipment: 6606D2 nylon/lycra sample #16120102-M coated with 0.15% low MW, 0.05% medium MW (ratio 3:1), 0.025% citric acid; silk medium molecular weight solution at 6%; silk low molecular weight solution at 6%; citric acid; unfiltered tap water; fabric sample style 6606D2; Krantz tenter frame; dye machine. 
     Coating Methods: the fabric is dyed in black with a dyeing machine using the following recipe:
         ERIOFAST BLACK M 6%;   Low molecular weight and medium molecular weight silk are diluted using tap water from 6% to the concentration for each of the 3 tests reported in Table 57;   The solution will be prepared for 104 liter pad liquor, with an estimating wet pick up rate of 65-70% for the processed fabric, and reduced by the end of each of the 3 tests to a minimum level of 60 liter (safety factor of 20% from the 50 liter minimum level of bath processing);   When medium molecular weight is used in the coating solution, the solution will be prepared with the following steps: mix low molecular weight, water, and citric acid for 2-3 minutes; add medium molecular weight and mix for additional 2-3 minutes;   When only low molecular weight silk is used, the silk solution is mixed with water and citric acid for 2-5 minutes;   Citric acid is added to the solution to correct the pH to 4-5, not exceeding a 0.25% liquor concentration;   The tenter frame is cleaned from any residue that may have built up on the bath or pad rollers from previous runs;   The approximately 700 yards dyed fabric is split into N=5 sections, N=3 sections of 220 yards each, N=1 section of 35 yards, and N=1 section of 5 yards;   The fabric is processed per Table 1, except for the 5 yards sample that is tested unprocessed for control;   For each test number, a sample of the solution is taken after it is mixed in the mixing tank, at approximately the middle of the fabric processing on the tenter frame and after the fabric is processed on the tenter frame bath; the solution is analyzed to quantify the silk solution concentration and determine any depletion rate at the tenter frame bath for fabric exposure;   During each trial, the first 5 meters of fabric sample are collected for testing, after approximately 110 meter additional 5 meter sample are collected, and the last 5 meter of processed fabric are collected;   After the fabric is cut during the middle of the run to collect the 5 meter sample, the fabric can be rolled on the same core;   All fabric rolls processed are assigned an identification number for traceability.

     Abrasion Method: 
     Fabric is not laundered; 
     Abradand: worsted wool; 
     Mass of Weight=9 kPa for apparel fabrics; 
     Abrasion cycle for the Martindale Abrasion Tester, 16 rubs required to complete a geometric shape, known as a Lissajous Figure (geometric figure that starts as a straight line, then becomes a widening ellipse, and narrows to again become a straight line; there are 16 rubs in one Lissajous figure); rub=one rotation of the two outer gears of the Martindale Abrasion Tester;
         Testing Conditions: 21° C. (±2° C.) and 65% RH (±5% RH);   End of test confirmed under a microscope for see through hole.       

     Interim results: the abrasion test is completed on N=3 samples; sample #1 was voluntary stopped at 1,388,251 cycles; sample #2 was voluntary stopped at 585,696 cycles. For comparative purposes, a sock normally wears at 5,000-10,000 cycles; 25,000 cycles typically represent a 95 percentile result.

Ratio of Silk to Vitamin C
 
     Samples 1-10 were used to examine the effect of silk to vitamin C ratio on serum gelation. Samples 1-3 with less vitamin C gelled quicker than samples 4 and 5. All other conditions were kept constant. Samples 6-8 with less vitamin C gelled quicker than samples 9 and 10. All other conditions were kept constant. It is concluded that decreasing the ratio of silk to vitamin C (increasing the amount of vitamin C), will lengthen the time to gel creation. At ratios with small amounts of vitamin C, days to gel creation did not vary greatly. 
     Physical Stimulation 
     Samples 3 and 11 were used to examine the effect of physical stimulation on serum gelation. Each sample was prepared under the same conditions. Sample 11 was vigorously shaken for about 3 minutes after addition of vitamin C. Treatment of 3 and 11 was otherwise the same. The shaking resulted in bubbles but did not significantly change gel creation time. 
     Temperature Treatment 
     Samples 1, 3, 6, 8, O-1, O-2, O-3, and O-4 were used to examine the effect of temperature treatment on serum gelation time. Samples 1, 6, O-1, and O-2 were identical other than temperature treatment. Samples 3, 8, O-3, and O-4 were identical other than temperature treatment. The two groups differed in silk to vitamin C ratio. Time to serum gelation was directly related to temperature treatment with a higher temperature resulting in quicker serum gelation. 
     Solution Volume 
     Samples 1, M and D were used to examine the effect of solution volume on serum gelation time. Samples M and D varied from sample 1 only by an increased solution volume. Samples M and D gelled in 5 days while sample 1 gelled in 8 days. Samples M and D were definitively noticed to be gelled on the day of gelling while sample 1 gelled over a weekend. 
     Additives 
     Samples E1, E2, E3, E4, L1, L2, L3, L4, L5, Jar 2, R1, RO-1 and RO-2 were used to examine the effect of additives on serum gelation time. Samples E1-4 contained Vitamin E. Only samples E1 and E2 contained vitamin C and only these two samples gelled. Vitamin E can be added to a solution to become a gel but it appears that another additive may be needed to create a gel. Samples L1-5 contained a form of lemon juice. Samples L1 and L4 had juice directly from a lemon while samples L2, L3 and L5 contained lemon juice from a plastic lemon container. Samples L4 and L5 did not have vitamin C while all others did. All samples gelled showing that lemon juice can create gel on its own. Amount of lemon juice and type of lemon juice had little effect on gelation time. Sample Jar 2 contained lemon grass oil which formed an albumen like substance when initially added. This sample also had vitamin C but gelation time was significantly quicker than with other vitamin C samples. Sample R1 contained rosemary oil, which seemed to be soluble, as well as vitamin C. The sample gelled in a similar time frame to other samples with only vitamin C. Samples RO-1 and RO-2 contained rose oil while only RO-1 had vitamin C. Only RO-1 gelled showing that rose oil will not create a gel quickly on its own. In both cases the rose oil was immiscible and visible as yellow bubbles. 
     Aqueous silk fibroin-based fragment solution and essential oils are immiscible liquids. In an embodiment, to increase the fragrance of the silk fibroin-based fragment solution, without entrapping oils within the solution, the solution is mixed with the essential oil with the use of a stir bar. The stir bar is rotated at a speed such that some turbulence is observed in the mixture, thus causing contact between the fragrant essential oil and the molecules in solution, adding a scent to the solution. Before casting of product from the solution, mixing may be stopped and the oil allowed to separate to the top of the solution. Dispensing from the bottom fraction of the solution into the final product allows for fragrance without visible essential oil within the final product. 
     Alternatively, the silk fibroin-based solution and essential oil can be combined with or without additional ingredients and/or an emulsifier to create a composition containing both ingredients. 
     In an embodiment, mixing of the solution as described above can reduce gelation time if the solution is used to create a gel formulation. 
     Vessel 
     Samples T1 and Jar 1 were used to examine the effect of casting vessel on serum gelation time. Jar 1 was cast in a glass jar while T1 was cast in an aluminum tube. Both samples gelled and did not affect serum gel time. 
     SUMMARY 
     All treatments of silk solution for gel solution were in a conical tube at room temperature unless otherwise stated. The ratio of silk to vitamin C did affect the ability of a solution to gel as ratios above 1:2 did not gel and a 1:2 ratio took twice as long as other lower ratios (5:1, 2.5:1, 1:1). Temperature affected gel creation time with higher temperatures resulting in quicker gel times. 50° C. treatment gelled in as quick as 2 days, 37° C. treatment gelled in as quick as 3 days, room temperature treatment gelled in 5-8 days and storage in a refrigerator took at least 39 days to gel. The effects of additives on gel creation were dependent on the additive. Vitamin E, Rosemary Oil and Rose Oil all had no effect on gel creation. Each of these additives did not prevent gelation or affect the time to gelation. Each also required the presence of vitamin C to gel. Lemon juice from a fresh lemon, pre-squeezed lemon juice from a plastic lemon container and lemon grass oil did affect gel creation. Without wishing to be bound by theory, it is believed that the lower pH as a result of these additives is the reason the additives had an impact on decreasing gelation time. Both lemon juice types were able to cause gelation without the presence of vitamin C. This occurred in the same number of days as with vitamin C. The lemongrass oil was able to decrease the number of days to gelation to 2-3 days. All additives appeared soluble other than lemongrass oil and rose oil. Rose oil remained in yellow bubbles while the lemongrass oil was partially soluble and formed an albumen like chunk. In an embodiment, oils that are not fully soluble, can still be suspended within the gel as an additive. Physical stimulation by shaking, vessel the solution was cast into and solution volume did not affect gelation time.

Silk Solution and Silk Gel Application to Fabric and Yarn Samples
 
     Three 50 mm diameter fabric samples from each of three different fabric materials, cotton, polyester, and nylon/LYCRA®, were placed in plastic containers. about 0.3 mL of about 5.8% silk fibroin solution was deposited using a 1 mL syringe and 18-gauge needle on two samples of each material, and allowed to sit for about 1 minute. About 0.3 mL of denatured alcohol (containing methanol and ethanol) was then deposited using a 1 mL syringe and 30-gauge needle on one of the silk-coated samples of each material. 
     In an additional experiment, silk gel with Rosemary Essential Oil (water, silk, ascorbyl glucoside, rosemary essential oil) was collected on a tip and applied to half the length of 2 pieces of 400 μm tencel yarn. One sample was then wetted with about 0.3 mL alcohol. 
     Silk Solution Dip Test 
     Polyester fabric samples were dipped in silk fibroin solutions of varying concentration. Samples were placed in incubator with air flow on foil and allowed to dry at about 22.5° C. for about 15.5 hours. Change in mass before and after silk coating was measured.

Silk Solution Spray Test
 
     A spray test was performed to verify the handle impact of silk fibroin solution sprayed on polyester fabric. About 0.5% silk fibroin solution was applied to a 4 inch by 4 inch square of polyester fabric using a spray gun from a distance of about 10 inches. Three passes were completed from left to right and from right to left (six passes total). Samples were placed in a 50° C. oven on aluminum foil over a water bath for about 1.5 hours. Methods were repeated with a second polyester fabric sample with an about 5.8% silk fibroin solution spray application. No change in material hand was observed in samples sprayed with either 0.5% or 5.8% solutions. Perceived increase in materials smoothness was observed for samples sprayed with either the 0.5% and 5.8% solutions.

     The products produced using the coating processes described above were tested for accumulative one-way transport capability (or index) and other properties using Association of Textile, Apparel &amp; Materials Professionals (AATCC) test method 195-2012 for the measurement, evaluation, and classification of liquid moisture management properties of textile fabrics. The details of the test methods are available from AATCC, and a synopsis of the methods and calculations is provided here. The absorption rate (ART) (top surface) and (ARB) (bottom surface) is defined as the average speed of liquid moisture absorption for the top and bottom surfaces of the specimen during the initial change of water content during a test. The accumulative one-way transport capability (R) is defined as the difference between the area of the liquid moisture content curves of the top and bottom surfaces of a specimen with respect to time. The bottom surface (B) is defined for testing purposes as the side of the specimen placed down against the lower electrical sensor which is the side of the fabric that would be the outer exposed surface of a garment when it is worn or product when it is used. The top surface (T) for testing purposes is defined as the side of a specimen that, when the specimen is placed on the lower electrical sensor, is facing the upper sensor. This is the side of the fabric that would come in contact with the skin when a garment is worn or when a product is used. The maximum wetted radius (MWRT) and (MWRB) (mm) is defined as the greatest ring radius measured on the top and bottom surfaces. Moisture management is defined, for liquid moisture management testing, as the engineered or inherent transport of aqueous liquids such as perspiration or water (relates to comfort) and includes both liquid and vapor forms of water. The overall (liquid) moisture management capability (OMMC), an index of the overall capability of a fabric to transport liquid moisture as calculated by combining three measured attributes of performance: the liquid moisture absorption rate on the bottom surface (ARB), the one-way liquid transport capability (R), and the maximum liquid moisture spreading speed on the bottom surface (SS B ). The spreading speed (SS i ) is defined as the accumulated rate of surface wetting from the center of the specimen where the test solution is dropped to the maximum wetted radius. The total water content (U) (%) is defined as the sum of the percent water content of the top and bottom surfaces. The wetting time (WTT) (top surface) and (WTB) (bottom surface) is defined as the time in seconds when the top and bottom surfaces of the specimen begin to be wetted after the test is started. 
     A moisture management tester (MMT) is used to perform the test. The accumulative one-way liquid transport capability (R) is calculated as: [Area (U B )—Area (U T )]/total testing time. The OMMC is calculated as: OMMC=C 1 *AR B_ndv +C 2 *R nvd +C 3 *SS B_ndv , where C 1 , C 2 , and C 3  are the weighting values*for AR B_ndv , R ndv  and SS B_ndv ; (AR B )=absorption rate; (R)=one-way transport capability, and (SS B )=spreading speed. Detailed calculations of these parameters, and other parameters of interest, are provided in AATCC test method 195-2012.

     Example 14. Antimicrobial Properties of Silk Coatings on Fabrics 
     The antimicrobial properties of silk coatings were testing on four materials: a cotton/LYCRA jersey (Ser. No. 15/051,201), a cotton/LYCRA jersey with 1% silk fibroin solution (sfs) bath coating (Ser. No. 15/070,701), a polyester/LYCRA finish after final setting (Ser. No. 15/042,003), and a polyester/LYCRA semi-finished 1% sfs bath coating (Ser. No. 15/070,702) (wherein LYCRA is the trade name of a polyester-polyurethane copolymer). AATCC test method 100-2012 for the assessment of antibacterial finishes on textile materials was used. The details of the test method are available from AATCC. Briefly, the tests were performed using tryptic soy broth as a growth medium, a sample size of 4 layers, autoclave sterilization, 100 mL Letheen broth with Tween for neutralization, a target inoculation level of 1-2×10 5  CFU/mL, 5% nutrient broth as an inoculant carrier and dilution medium, a contact time of 18 to 24 hours, and a temperature of 37+/−2° C. 
     The results of the tests are summarized in Table 69 and are depicted in  FIG. 63  to  FIG. 67 , and illustrate the superior antimicrobial performance of the silk-coated fabrics.

     Example 17. Characterization of Silk Coatings on Polyester Fabrics 
     Scanning electron microscopy (SEM) analysis was performed using a Hitachi S-4800 field-emission SEM (FE-SEM) operated at 2 kV accelerating voltage. Pieces from each sample were sectioned using a razor blade and placed on carbon adhesive tape mounted on aluminum SEM stubs. A coating of iridium approximately 2 nm thick was applied via sputter deposition in order to minimize the buildup of surface charge. 
     The samples used in the SEM study are described in Table 72. SEM micrographs for fabric samples are shown in  FIG. 80  to  FIG. 120 .

     The fabric SEM results show that the silk solution has very clearly been deposited along and between individual polyester fibers. The use of 0.1% silk solution results in less coating than 1.0% silk solution. The use of a bath for 0.1% silk solution, with an average molecular weight of 41 kDa, results in uniform coating along fibers with large, smooth features. The use of a spray with a 0.1% silk solution, with an average molecular weight of 41 kDa, in coating along fibers as well as connected, webbed coating between fibers. The use of a spray for 0.1% silk solution, with an average molecular weight of 11 kDa, results in uniform coating along fibers with small, spotted/ribbed features. The use of a stencil for 0.1% silk solution, with an average molecular weight of 11 kDa, results in coating along fibers that has clear edges and delineation between coated and non coated sides. The use of a bath for 1.0% silk solution, with an average molecular weight of 41 kDa, results in thick coating along fibers as well as thick connected, webbed coating between fibers. The use of a bath for 1.0% silk solution, with an average molecular weight of 11 kDa, results in coating along all sides of individual fibers. Coating appears uniform on surface with many single point extrusions. The use of a spray for 1.0% silk solution, with an average molecular weight of 41 kDa, results in coating along fibers as well as connected, webbed coating between fibers, which was thicker than that observed using 0.1% silk solution. The use of a stencil for 1.0% silk solution, with an average molecular weight of 41 kDa, results in coating along fibers and between fibers, and the coating appears well organized. The SEM results demonstrate that the silk coating has been applied as an even, thin, uniform coating to the fibers of the fabric. This illustrates the surprising result that the silk coating was applied to the fibers without the use of any additives or cross-linking, using a water based delivery system.

     The results show that the silk coatings are applied uniformly. Little to no variation is observed in the characteristics or topology of the coated polyester films. Surprisingly, the coating is even, uniform, and thin. Furthermore, surprising, the silk coated the fibers without any additives or cross-linking using a water-based system. 
     Optical profiling was carried out using a Zygo New View 6200 optical profilometer. Two locations on each sample were randomly selected and measured with 10× magnification. The results are shown in  FIG. 121  to  FIG. 144 . The results indicate that the silk-coated samples have a homogeneous deposition of silk fibroin. Surface roughness features observed in the control are visible after silk coating on Mylar films, which is consistent with the presence of a relatively thin silk film that is forming a conformal coating on Mylar. The results substantiate the uniformity of the coating, and demonstrate that silk can be stenciled into discrete locations. 
     Contact profilometry was performed and the cross-sectioned samples were examined by SEM. Results are shown in  FIG. 145  to  FIG. 148 . For sample FIL-10-SPRAY-B-10MYL, the thickness ranged from approximately 260 nm to 850 nm in 4 locations analyzed. For sample FIL-10-BATH-B-01MYL, the coating ranged from approximately 140 nm to 400 nm in 4 locations. SEM images from cross-sections show similar trends, with one location on sample FIL-10-SPRAY-B-10MYL having a cross-section that measures approximately 500 nm and one on FIL-10-BATH-B-01MYL measuring approximately 180 nm.

     Example 21. Manufacturing Processes for Silk Coated Textiles and Leathers 
     Silk coated textiles and leathers may be manufactured on larger scales according to the methods provided herein using standard textile and leather manufacturing equipment with the addition of silk fibroin-based protein fragment coating steps (e.g., via bath, stencil, or spray methods). For example, a tentering and stentering frame, representing a typical process for applying the silk solution in a continuous process, may include the following units:

     Example 22. Flammability Testing for Silk Coated Textiles 
     Flame resistant testing of textiles and other products of the invention, coated with silk fibroin-based protein fragments prepared using any of the methods disclosed herein may be performed using methods known to those of skill in the art, and may provide results that demonstrate flame resistant property for textiles and other products coated with silk fibroin-based protein fragments relative to uncoated textiles. Flame resistant testing of fabrics coated with silk fibroin-based protein fragments may be determined, for example, using 16 C.F.R. 1615 or 16 C.F.R. 1616 or other suitable versions of flame resistant testing standards known to those of skill in the art. Briefly, a piece of textile coated with silk fibroin-based protein fragments prepared using any of the methods disclosed herein, after 25 washing cycles, is cut into 3.5 inches wide×10 inches long rectangle specimen. One specimen is suspended in a test chamber through a specimen holder. The test chamber should be a steel chamber and at least with dimensions 32.9 cm. (1215/16 in.) wide, 32.9 cm. (12 15/16 in.) deep, and 76.2 cm. (30 in.) long. The specimen is suspended in the test chamber vertically along the length of the specimen, and is lit up by a burner. Then the char length is measured. The testing is repeated for 5 times and average char length is calculated based on the individual result. The same testing is performed with a textile without a silk coating as a control. The specimen after 5, 10, 15, 20, 30, 35, 40, 45, and 50 washing cycles are also tested. The average char length needs to be less than 7 inches (177.8 mm) to be determined as flame resistant. The char length is the value used to evaluate passing grade for sleepwear flammability. 
     Two representative fabrics were used in the flammability tests. A cotton interlock fabric coated with 1% silk fibroin solution (Ser. No. 16/021,103) was compared to the same fabric without (Ser. No. 16/021,101) coating. A polyester double knit fabric coated with 1% silk fibroin solution (Ser. No. 16/021,104) was compared to the same fabric without coating (Ser. No. 16/021,102) with 1% silk fibroin solution. The SFS used to coat the fabrics in these experiments had a weight average molecular weight range of about 32-44 kDa. 
     Results for a cotton interlock fabric are shown in  FIG. 151  and  FIG. 152 . The coating with silk fibroin-based protein fragments does not adversely affect the flammability of the fabric. Similarly, the results for a polyester double-knit fabric, shown in  FIG. 153  and  FIG. 154 , also indicate that coating with silk fibroin-based protein fragments does not adversely affect the flammability of the fabric. No significant differences between samples made from same material (cotton or polyester) were observed. The differences between fabric made with the same material for afterglow and after flame time were not significant. Cotton, as expected, was flammable and none of the samples were left after the test. 
     Example 23. Abrasion Testing for Silk Coated Textiles 
     Abrasion testing of textiles and other products coated with silk fibroin-based protein fragments prepared using any of the methods disclosed herein may be performed using methods known to those of skill in the art, and may provide results that demonstrate improved resistance to abrasion for textiles and other products coated with silk fibroin-based protein fragments relative to uncoated textiles. Improved resistance to abrasion is useful in applications such as upholstery, including upholstery designed for home, automotive, aircraft, or other uses. Abrasion testing of fabrics coated with silk fibroin-based protein fragments may be determined, for example, using ASTM Method D4966-12 (Standard Test Method for Abrasion Resistance of Textile Fabrics (Martindale Abrasion Tester Method), ASTM, 2013) or other suitable versions of ASTM Method D4966. Briefly, abrasion resistance is measured by subjecting a textile specimen to a rubbing motion that takes the form of a geometric figure, beginning with a straight line, which becomes a gradually widening ellipse until it forms another straight line in the opposite direction, after which the motion reverses repeatedly. The rubbing occurs under known conditions of pressure and abrasive action. A Martindale Abrasion Tester (commercially available from James H. Heal Co., Ltd.) is used for testing. Resistance to abrasion is evaluated. 
     Four samples were tested using ASTM Method D4966-12. Sample 16021101 was a 100% cotton interlock fabric. Sample 16021102 was a 100% polyester double knit. Sample 16021501 was the 100% cotton interlock fabric after bath coating (as described herein) with 1% silk fibroin solution (SFS). Sample 16021502 was the 100% polyester double knit fabric after bath coating (as described herein) with 1% SFS. The SFS used to coat the fabrics in these experiments had a weight average molecular weight range of about 11 kDa.

     Upon examination of the figures, there are some formations visible on top of controls 16041301 and 16041304, they can be identified as cyclic trimer, which may be a polyester byproduct, salt, or excess dye. The low molecular weight coated fibers present broken bridges between fibers. It may be noted that at low concentration the low molecular weight conglomerates in globs; more than at equivalent concentrations with the medium molecular weight. The medium molecular weight fibers have excellent polyester fibers at any concentration and temperature and a network of bridging fibers may be more visible at higher concentrations. 
     Example 25: Examination of the Effect of Various Parameters on SFS Coatings 
     This experiment tested the impact of SFS molecular weight with a 1% concentration at 3 different drying and curing temperature with different drying and curing temperature time. The fabrics were characterized by mass and Liquid Moisture Management Properties of Textile Fabrics (MMT) following AATCC Test Method 195-2012 (Tables 78-80).

     The collective results are provided in  FIG. 193  for each tested material. However, sample 16040102 did not produce acceptable results and 15042001 is provided as a reference, which is not coated. 
     The results of these analyses are provided in table form in  FIG. 194 . Specifically,  FIG. 194  describes the grading for each tested sample (medium and low molecular weight samples) in terms of wetting (top and bottom), absorption rate (top and bottom), wetted radius (top max and bottom max), spreading speed (top and bottom), accumulative one-way transport, and overall moisture management capability (OMMC). 
     From the presented results the SFS coated fabric has an impact on the MMT grading of fabric, significantly improving the accumulative one way transport index from the non-coated standard of grade 2 to the SFS coated grades of 4-5 depending on molecular weight and curing time and temperature. While with the OMMC index the non-coated standard has a grade of 1 compared to the SFS coated grades of 3 independent of tested variables. 
     Example 26: Impact of SFS Concentration at Low and Medium Molecular Weight Samples 
     This experiment tested the impact of SFS concentration at 2 molecular weights using the same drying and curing temperature time. The fabrics were characterized by mass and Liquid Moisture Management Properties of Textile Fabrics (MMT) following AATCC Test Method 195-2012. 
     The experimental parameters are provided in Table 81.

     Sample test results for each variable tested are reported in the table set forth in  FIG. 195 , where sample 15042001 is a non-coated control. Sample test grading for each variable tested are reported in the table provided in  FIG. 196 . 
     From the presented results the SFS coated fabric has an impact on the MMT grading of fabric, significantly improving the accumulative one-way transport index from the non-coated standard of grade 2 to the SFS coated grades of 5 depending on molecular weight (low vs. medium) and SFS concentration. While with the OMMC index the non-coated standard has a grade of 1 compared to the SFS coated grades of 3 independent of tested variables. 
     Example 27: Tested Impact of Curing Time on Coatings at Two Molecular Weights 
     This experiment tested the impact of curing time at 150° C. and 200° C. with SFS at 1% concentration at two molecular weights. The fabrics were characterized by mass and Liquid Moisture Management Properties of Textile Fabrics (MMT) following AATCC Test Method 195-2012. 
     The experimental parameters are provided in Table 83.

     Sample test results for each variable tested are reported in the table set forth in  FIG. 197 , where samples 16041301 and 16041304 are non-coated fabrics for reference. Sample test grading for each variable tested are reported in the table provided in  FIG. 198 . 
     From the presented results the curing temperature time may reduce the MMT grading when 1% SFS coated fabric is exposed between 5-10 minutes at 150° C. or 200° C. At the other curing time tested 3 and 5 minutes at 150° C. or 200° C. there is no apparent impact on accumulative one-way transport or OMMC grades. 
     Example 28 
     This experiment tested the impact of temperatures of 65° C., 150° C., and 200° C. at the minimum drying and curing time with 1% SFS at two molecular weights. The fabrics were characterized by mass and Liquid Moisture Management Properties of Textile Fabrics (MMT) following AATCC Test Method 195-2012. 
     The experimental parameters are provided in Table 85.

     Sample test results for each variable tested are reported in the table set forth in  FIG. 199 , where samples 16041301, 16041304, and 15042001 are non-coated fabrics for reference. Sample test grading for each variable tested is reported in the table provided in  FIG. 200 . 
     From the presented results the curing temperature of 65° C., 150° C., and 200° C. has limited to no impact on the MMT grading when 1% SFS coated fabric is exposed for respectively 3, 5, and 10 minutes. Medium molecular weight coated fabrics have faster wetting time than low molecular weight coated fabrics or non-coated control fabrics. Low molecular weight coated fabrics exhibit a faster spreading time than medium molecular weight coated fabrics or non-coated control fabrics. Medium molecular weight coated fabrics or low molecular weight coated fabrics perform equal to or better than non-coated control fabrics in terms of Accumulative One Way Transport and OMMC.

     Post curing the fabric is left to condition at room temperature for 24 hrs. 
     Samples are cut to 8 cm by 8 cm square and delivered to MSC lab for MMT testing. 
     After conditioning the fabric is tested for drapability using the drape elevator test modified to accommodate the MMT sample size dimension. After placing the sample on the testing jig an image is recorded with a camera; the elevator is lowered until no more contact is made with the fabric by the elevator table and a second image is recorded. Image analysis of the fabric area is performed through Photoshop. A drape coefficient is calculated with the following formula: 
                 Drape   ⁢           ⁢   Coefficient     =         Ad   -     S   ⁢           ⁢   1           S   ⁢           ⁢   2     -     S   ⁢           ⁢   1         *   100       ,         
where Ad is the vertical projection of the draping sample, S1 the area of the round sample holder, and S2 is the area of the sample.
 
     Example 33: Antibacterial Study 
     An experiment is devised for evaluating the antibacterial proliferation on SFS coated fabrics through multiple washing cycles. Specifically, the study will examine whether bacteria will adhere to silk-coated fabric following wash. 
     The study will mimic the bacterial deposition on textile material during regular exercise and home laundering. 
     The antibacterial testing will be at 0, 1, 10, and 25 minute cycles using a front loading washer with water at less than 30° C. The fabrics will be air or tumble dried at less than 50° C. 
     A 13.5×13.5 inch fabric swatch will spotted with eight (8) inoculation sites and tested following washing at the disclosed intervals to determine the presence and quantity of bacteria. 
     Example 34: Drapability of Exemplary Silk Coated Fabrics 
     The following coated fabrics were prepared according to the processes described herein and tested for drapability according to the method described in Mizutani, et al., “A New Apparatus for the Study of Fabric Drape.”  Textile Research Journal  (2005) 75: 81-87. 
     The materials in the method include a sample and camera holding fixture, sample holding fixture of 5 cm in diameter, an elevator plane, and a camera. The fabric specimens were 8×8 cm 2 . The procedure included: (1) cutting the sample to 8×8 cm square (8 cm diameter may be used); (2) placing the specimen at the center of a fixture; (3) elevating the fixture to examine the draping of the specimen; and (4) capture an image of the specimen. 
     The images were opened in Adobe Photoshop CS5.1 and the lazo function was used to delmit the perimeter of the specimen. The measurement function was then used to count all the pixels within the selected area and such data was saved. This process was repeated for each specimen. A drape coefficient was calculated based on the following formula: 
                 Drape   ⁢           ⁢   Coefficient     =         Ad   -     S   ⁢           ⁢   1           S   ⁢           ⁢   2     -     S   ⁢           ⁢   1         *   100       ,         
where Ad is the vertical projection of the draping sample, S1 is the area of the round sample holder, and S2 is the area of the sample. The data for such analysis is set forth in Table 90 and associated  FIG. 202 .

     the foregoing study, silk solution, drying parameters, and silicone compositions were used to adjust the drapability for a variety of coated fabrics. 
     Example 35: Effect of Mechanical and Steam Finishing on a Silk Coated Fabric 
     A sample was prepared as described herein, wherein the sample was a polyester/LYCRA non-finished fabric coated with a 1% SFS (medium molecular weight) that was dried at 200° C. for 3 minutes. In addition, the same fabric was subjected to a 41 minutes dryer cycle at normal setting on medium temperature (mechanical finishing) and to steaming on a steam table for 5 seconds (steam finishing). The resulting samples, after finishing, were examined for drapability as shown in Table 91 and in  FIG. 203 .

     While the mechanical finishing with the dryer reduced the drapability coefficient (i.e., less stiff fabric), the steam finishing increased the drapability coefficient (i.e., stiffer fabric). 
     Results of experiments measuring solution depletion calculation during coating are shown in  FIG. 204 , and illustrate the amount of silk fibroin deposited on fabrics. 
     Additional results of moisture management testing of coated fabrics are given in  FIG. 205  to  FIG. 210 . 
     Additional results from antimicrobial testing of coated fabrics are given in  FIG. 211 . 
     Example 36: Effectiveness of Diluting Silk with Tap Water 
     The silk compositions described herein are stable and effective when prepared with tap water. 
     A 1:1 ratio between the silicone and silk gave a softer hand to a resulting fabric with a 20:1 ratio between silk/silicone and citric acid. 
     The parameters for the study between tap water and reverse-osmosis/deionized (RODI) water are set forth in Table 92.

     The results of the foregoing study indicated that there was no difference in the resulting properties of those silk solutions prepared in RODI water as compared to unfiltered tap water. Moreover, the silk solutions did not precipitate with the use of tap water. 
     Example 37: A Study of Silk Solution as a Wicking Agent 
     Silk solutions as disclosed herein can be adopted as a wicking agent in common finishing recipes to balance the water repellency of silicone softeners. 
     The present test is a modification to AATCC-79-2014 that was prepared to accommodate the dimensions of the tested samples (8×8 cm samples), where the AATCC test is designed for a sample of 150 cm in diameter. Here, the samples are cut in 8 cm by 8 cm and placed in a drapability jig suspended on a 7 cm diameter round metal hoop so the back of the fabric has no surface contact. An RODI water drop is dispensed with an eye dropper from approximately 3 cm above the fabric. A video imaging recording captures the time from the water drop contacting the fabric until its full absorption or up to 30 seconds. 
     Without silk, the water drop stays on the fabric surface up to the test end of 30 seconds; while in the presence of silk the water drop is absorbed in as long as 4 seconds or as fast as 1 second depending on the tested variables. 
     The parameters for this study are set forth in Table 95 with the results set forth in  FIGS. 212 and 213 .

     Example 38: A Study of Dyeing Polyester and Nylon Fabrics Followed by the Application of Silicone and Silk Solution Through Exhaust 
     The objective of this study is to evaluate the application of silk fibroin solution on fabrics made with polyester/spandex and nylon/spandex. The application will take place after dyeing the fabrics at exhaust. In addition, silicon softeners will be added to the silk solution to improve the hand of the fabrics. Liquid Moisture Management testing (MMT) according to AATCC 195-2012, a drapability test according to the drape elevator method modified to accommodate samples dimension, and a water drop test will be used to characterize the fabrics. 
     This study was performed for research and development purposes to evaluate the feasibility to apply silk fibroin solution at exhaust post dyeing. In addition, commercially available silicon softeners were mixed with different percentage and molecular weight of silk fibroin solution to improve hand and drapability of the fabric.

     The fabric sample is placed in the 5-pound pressure dryer along with enough dunnage to total 3-pound load. The tub is filled with water. The following wetting and scouring agent are added for pre-scouring process: 1.0% wetter and 2.0% scour. 
     The solution was heated to 180° F. for 20 minutes. The solution was dropped and rinsed. To the solution was added 1% wetter, acetic acid to pH 5.0, with a leveler used as desired, and heated to 110° F. Dissolved dyes were added and heated to 180° F., with the temperature held for 10 minutes. The solution was then heated to 265° F. at 3° F./minute and held at 265° F. for 90 minutes. 
     The solution was then cooled to 180° F. and the color shade was sampled. Upon acceptance, the solution was dropped and rinsed three times. The solution was further cooled to 140° F. and hydro was added for 15 minutes. The solution was again dropped and rinsed 2-3 times until clean. The solution was then cooled to 110° F. and softener was added (silicone and silk solution at the concentration reported in Table 96) for 10 minutes. The solution was dropped and the fabric was removed from the machine. 
     The fabric is dried by first removing excess fluid with Hydroextractor followed by a dryer cycle at normal setting with low temperature. Samples are cut to 8 cm by 8 cm square and delivered to MSC lab for MMT testing. Samples cut in 8 cm by 8 cm that are not tested for MMT are placed in the drapability jig suspended on a 7 cm diameter round metal hoop. A RODI water drop is dispensed with an eye dropper from approximately 3 cm above the fabric. A video image recording captured the time from the water drop contacting the fabric until its full absorption or up to 60 seconds. 
     After conditioning, the fabric is tested for drapability using the drape elevator test modified to accommodate the MMT sample size dimension. After placing the sample on the testing jig an image is recorded with a camera; the elevator is lowered until no more contact is made with the fabric by the elevator table and a second image is recorded. Image analysis of the fabric area is performed through Photoshop. A drape coefficient is calculated with the following formula: 
               Drape   ⁢           ⁢   Coefficient     =         Ad   -     S   ⁢           ⁢   1           S   ⁢           ⁢   2     -     S   ⁢           ⁢   1         *   100           
where Ad is the vertical projection of the draping sample, S1 the area of the round sample holder, and S2 is the area of the sample. The fabrics with a water drop test &lt;3 seconds and a drapability of &lt;90 were submitted for MMT testing.

     Letheen broth with tween as neutralizer for enumeration; 
     BD Difco Leethen broth #268110; and 
     Concentrated Clorox regular bleach. 
     Equipment. 
     The following is a list of equipment used from the fabric sample preparation and study execution: 
     Werner Mathis MA-881 padder/coater; 
     Curing frame; 
     Across International Oven FO-19140; 
     Balance Veritas M314-AI; 
     Universal plastic PH test strip; and 
     Tempo Filler and Reader from BioMerieux for enumeration. 
     Methods. 
     Fabric Sample Preparation. Silk coated fabric is prepared following SOP-TEMP-001. Silk solution concentration at 0.05% is applied to the fabric with bath immersion with the padder&#39;s roller pressure setting at 50 and 200 C curing time for 3 minutes. Fabric sample with 13.5 inches by 13.5 inches are divided with a permanent marker to delimit 8 equivalent areas. 
     Bacteria Inoculation. At the center for each of the 8 areas 2×10 7  cfu of bacteria solution was inoculated. The total load per washing cycle was expected to be 1-2×10 8  CFU. The inoculated fabric was allowed to air dry for 60 minutes. 
     Washing Cycle. The inoculated fabric was placed in the washing machine with 1.8 kg of cotton towel as dunnage with 50 mL of detergent. A washing machine cycle at gentle setting with warm water at less than 30 C was completed. The inoculated fabric was removed from the washing machine and allowed to air dry for 120 minutes. After each washing cycle the dunnage was bleached with 120 mL concentrated Clorox regular bleach to eliminate any bacteria transfers from the tested specimen to the dunnage. 
     Bacteria Enumeration. At preset intervals, from the dried inoculated fabric 2 square samples were cut out and the bacteria count was enumerated following, as a guideline, the enumeration method of AATCC 100. 
     Study Execution. For the fabric to be inoculated, multiple bacteria inoculation washing cycles and testing for bacteria enumeration at different intervals were executed on each tested fabric. For the fabric with no inoculation, the same washing cycle and testing for bacteria enumeration at the same intervals were used. Since at enumeration swatches of fabric were removed from the fabric, to maintain the total bacteria load per washing cycle, an additional piece of control fabric was added to the dunnage. The additional fabric was inoculated with the balance of bacteria load. For example, after 1 washing cycle the additional fabric received 4×10 7  of bacteria load. 
     Methods of Analysis. Analysis was performed to determine antibacterial properties of the fabric following, as guidelines, the enumeration method of AATCC 100: Antibacterial Finishes. The fabric sample is placed in a polypropylene container with 100 mL of Letheem broth and shaken for 60 seconds. The bacteria count as then enumerated with Tempo filler reader. At each tested interval two side by side tested samples are cut out from the fabric and tested with duplicates. After each enumeration the fabric was tested for any odor intensity and for any changes between T=0 and the enumerated tested sample. Odor is evaluated on the following scale: 0=no odor; 1=very weak (odor threshold); 2=weak; 3=distinct; 4=strong; 5=very strong; and 6=intolerable. After each enumeration, high resolution image recording was taken for each sample so enumerated. 
     The fabric surfaces were also examined during the study for both the coated and non-coated fabrics by taking microscopic images of the coated and non-coated samples prior to washing, after one washing, and after 10 washings. A qualitative analysis of the microscopic images was performed to observe the % foreign matter coverage area on the observable fibers. The coated inoculated fibers displayed little or no foreign matter on their observable surfaces as compared to the non-coated inoculated fibers. The presence of silk does not contribute to increased bacteria adherence on the fabric surface, while any bacteria that may be deposited on the surface it can be removed through a standard home laundering cycle. As described herein, bacteria did not appear to adhere to the coated materials after washing. 
     Example 40. A Water Drop Study with Silk and Silicone Coated Fabrics 
     A study was performed to determine the effect of water wicking on fabrics coated with silk and silicone that have been treated with citric acid. 
     As shown herein, citric acid does not function as a wicking agent. However, with a 1:1 ratio of silk/silicone at 0.25%, the water took a longer time to absorb than that observed with previously described water drop studies. 
     The parameters for a first study are set forth in Table 97 and 98. The results of this study are illustrated in  FIGS. 215 and 216 .

     Example 41. Coating Cotton, Cashmere. And Cashmere/Silk Blends 
     Example 41a: A knitted and scoured cashmere panel (14″×20″) is soaked for 15 minutes in a 0.25 wt % solution of liquid silk (5 L), then spun dry for 10 seconds. The panel is then soaked for 5 minutes in water (5 L) and spun dry for 10 seconds. The panel is then soaked again in water (5 L) for 5 minutes and spun dry for 10 seconds. The panel is dried at 60° C. for 30 minutes. Panels are tested for hand and pilling. 
     Example 41b: A knitted and scoured cashmere/silk blend panel (4″×4″) is soaked for 15 minutes in a solution (500 mL) of silk (0.25 wt %) and glutaraldehyde-sodium bisulfate complex (0.1 wt %), then padded at 20 psi. The panel is then soaked for 5 minutes in water or alcohol solution (500 mL) and padded at 20 psi. The panel is then soaked again in water or alcohol solution (500 mL) for 5 minutes and spun dry for 10 seconds. The panel is dried at 60° C. for 5 minutes. Panels are tested for hand and water absorbency. 
       FIG. 217A  illustrates a silk-coated cotton SEM image; scalebar represents 2 μm.  FIG. 217B  illustrates a silk-coated cotton SEM image; scalebar represents 10 μm.  FIG. 218  illustrates manipulating water absorbency of liquid silk coated fabric. The time needed for a standard water drop to fully absorb into the fabric is recorded, and varies according to the silk treatment.  FIG. 219  illustrates various process parameters for coating fabrics.  FIG. 220  illustrates that liquid silk application significantly reduces pilling on cashmere; the pilling score of each cashmere panel, as measured according to ISO 12945-1: Score 5=No change; Score 4=Slight surface fuzzing and/or partially formed pills; Score 3=Moderate surface fuzzing and/or moderate pilling, pills of varying size and density partially covering the specimen surface; Score 2=Distinct surface fuzzing and/or severe pilling, pills of varying size and density covering a large proportion of the specimen; Score 1=Dense surface fuzzing and/or severe pilling, pills of varying size and density covering the whole of the specimen surface. Silk Formulation A: 0.05% M Silk; pH unadjusted, STI-18050801-T004. Silk Formulation B: 0.25% M Silk; pH 9.25, STI-18050801-T009. Silk Formulation C: 0.25% 3 L1M Silk, pH unadjusted, STI-18050801-T005.  FIG. 221A  (control) and  FIG. 221B  (cashmere treated with silk) illustrate cashmere coating coverage by scanning electron microscopy (SEM); as liquid silk and cashmere bond naturally, SEM demonstrates that liquid silk smooths and refines cashmere fibers.  FIG. 222A  (microscopic image) and  FIG. 222B  (dye intensity chart) illustrate deposition of FITC labeled silk fragments preferentially on cashmere cuticles; cuticle edges are 15-20 microns apart, and exhibit more fluorescence than the cuticle faces. (20× objective; laser power: 12%; gain: 600; gamma: 0.45).  FIG. 223  illustrate silk protein binding and smoothing the “scales” of wool to the core fiber, preventing the “Velcro-like” effect that is responsible for wool&#39;s shrinkage and inability to withstand washing; additional data shows wool+liquid silk is water resistant, stable and shrink-resistant following washing while matching or improving pilling.  FIG. 224  illustrates improved washability of wool by area dimensional change on wool tubes finished with liquid silk compared to untreated wool tubes. Liquid silk improves area dimensional change about twofold.  FIG. 225A-225D  illustrates SEM images of silk coated wool. 
     Example 42. Coating Synthetic Materials 
     Example 42a: Polyester Coating—Polyester fabric panels (13″×13″) were coated with a 0.1 wt % liquid silk solution using a pad-dry-cure method. The liquid silk solution is comprised of 3 parts Liquid Silk Formulation A and 1 part Liquid Silk Formulation B. The pH is adjusted to the desired range using pH adjusters commonly used in the field. The panels are soaked for 3 seconds and passed through a padder, after which they are transferred to an oven and dried for 90 seconds at 130° C. The samples are allowed to rest overnight, after which they are tested for silk deposition, hand, and performance (moisture management, abrasion resistance, pilling resistance, stain release, odor release, SEM, fluorescence microscopy). 
       FIG. 226  illustrates the coating coverage of silk fragments on polyester as shown by scanning electron microscopy (SEM); SEM confirms that after application of liquid silk, coating coverage is similar or greater than other commercial coatings for polyester.  FIG. 226  A illustrates polyester unfinished control sample, showing fibers with no coating.  FIG. 226B  illustrates polyester finished with silk, showing coated layers on the polyester fibers.  FIG. 227  illustrates EDS Data on Polyester Related Experiments; polyester fabric was coated in 6% silk ( FIG. 227C ) and energy-dispersive X-ray spectroscopy (EDS) was used to determine chemical content ( FIG. 227  A and  FIG. 227B ); EDS suggests regions between fibers ( FIG. 227B ) show nitrogen content due to silk depositions regions.  FIG. 228  illustrates liquid silk coated polyester absorbency; the results indicate that the coated material exceeds commonly accepted industry criteria for absorbency, and outperformed commercial counterparts after 50 laundering cycles.  FIG. 229  illustrates dry rate in polyester samples; in general liquid silk coated polyester dried faster than commercial control before laundering and after multiple laundering cycles; AATCC Test Method 201-1013 Heated Plate Method; higher values indicate faster dry rate (silk+mechanical denotes a second water pass and drying process).  FIG. 230  illustrates vertical wicking and abrasion resistance in polyester samples.  FIG. 230A : liquid silk coated polyester demonstrated improved wicking at 5 minutes vs. unfinished fabric after 3 laundering cycles.  FIG. 230B : liquid silk improves abrasion resistance of polyester fabrics, and outperformed the commercial standard.  FIG. 231  illustrates pilling resistance in polyester liquid silk coated fabric which outperforms the commercial standard.  FIG. 232A  and  FIG. 232B  illustrates silk-coated Nylon SEM images.  FIG. 233  illustrates fluorescence microscopy images for silk-coated vs. control;  FIG. 233A : FITC-Silk Coated Nylon; scale bars represent 107 μm.  FIG. 233B : Uncoated Nylon Control; scale bars represent 53 μm. Nylon coated in FITC-Silk showed increased fluorescence due to the FITC-silk coating; 5% enhancement.  FIG. 234  illustrates coating coverage on Nylon: scanning electron microscopy (SEM) confirms application of liquid silk.  FIG. 234A : Nylon unfinished control.  FIG. 234B : Nylon with silk finish—coated silk layers also adopt clear surface features.  FIG. 235A  illustrates absorbency performance of coated Nylon; liquid silk coated nylon exceeded commonly accepted industry criteria for absorbency, and outperformed commercial counterparts after 50 laundering cycles (AATCC Test Method 79-2013; smaller values indicate faster absorbency, silk+mechanical denotes a second water pass and drying process).  FIG. 235B  illustrates dry rate performance in coated nylon; liquid silk coated nylon dried faster than commercial control before laundering and after multiple laundering cycles (AATCC Test Method 201-1013 Heated Plate Method; higher values indicate faster dry rate; silk+mechanical denotes a second water pass and drying process).  FIG. 236A  illustrates vertical wicking performance; Nylon liquid silk coated nylon demonstrated improved wicking at 5 minutes vs. commercial finish after 3 laundering cycles (AATCC Test Method 197 (modified); higher values indicate better wicking; silk+mechanical denotes a second water pass and drying process).  FIG. 236B  illustrates abrasion resistance performance; Nylon liquid silk coated improves abrasion resistance of nylon; liquid silk coated nylon matched the commercial standard Abrasion Resistance—ASTM Standard D4966-12Eε1 (accelerated); testing ended when fabric first demonstrated abrasion or broke, whichever happened first; instead of wool, Trizact was used. 
     Example 42b: Odor release—Sour milk test (Odor Properties of Textiles Assessment from Pasteurized Cows&#39; Milk). This test method follows IAC Biofouling of Textiles from Pasteurized Cow&#39;s Milk, and includes modifications. The general procedure involves souring the milk using citric acid, placing the milk solution on the fabric, and allowing it to sit open for 3 days. Afterwards, the samples were sent out for washing and drying. Following the washing and drying process, the samples were resealed in clean jars. The samples were stored at room temperature for 24 hours. Odor presence was assessed after 24 hours by opening the jars and wafting the samples for presence of odor. The strength of the odor was rated from 1-5, where little to no odor present was rated (1) and pungent odor present was rated (5). 
       FIG. 237  illustrates the Sour Milk Test Experimental Results; liquid silk coated fabrics reduced odor more than both finished and unfinished fabrics.  FIG. 238A  and  FIG. 238B  illustrates Sour Milk Test Experimental Results; liquid silk coated fabrics reduced odor more than both finished and unfinished fabrics.  FIG. 239  illustrates biocompatibility of liquid silk coated fabrics (by the FDA standard test to show compatibility for contact with human skin); liquid silk coated fabrics demonstrated no reactivity; multiple commercial performance fabrics failed biocompatibility testing (0=No reactivity around or under specimen (passed); 1=Slight reactivity, some degenerated cell under test article (passed); 2=Mild reactivity, zone limited to area under the test article (passed); 3=Moderate reactivity, zone of lysis extending specimen size up to 1 cm (failed); 4=Severe, zone of lysis extending farther than 1 cm beyond specimen (failed)).
