Title: Soft through-air dried facial tissue

Description:
BACKGROUND OF THE DISCLOSURE 
     Tissue products, such as facial tissues, paper towels, bath tissues, napkins, and other similar products, are designed to include several important properties. For example, the products should have good sheet bulk, a soft feel, and should have sufficient strength and durability to withstand use. Further, to improve wiping utility, it may be desirable to provide the product with a degree of surface texture. 
     Unfortunately, however, when steps are taken to increase one property of the product, other characteristics of the product are often adversely affected. 
     One means to balance important tissue product properties is to manufacture the products by processes that do not compress the nascent web during drying. Such processes often consist of non-compressive drying techniques in which the nascent web is molded to the contours of a patterned fabric that supports the web as it is dried. The wet molded web is typically dried by passing heated air through both the fabric and the wet web as it is transported over a cylindrical dryer. In this manner the web is imparted with a three-dimensional pattern and its bulk is maintained. 
     One widely used non-compressive drying process used to manufacture tissue products is through-air drying, which consists of transferring a wet-laid web to a coarse, highly permeable through-air drying fabric imparted with three-dimensional surface topography. The wet-laid web is molded to the through-air drying fabric and is supported by the fabric until it is at least almost completely dry. The resulting dried web is softer and bulkier than compressively dewatered tissue webs, such as wet-pressed webs, because fewer papermaking bonds are formed and because the web is less dense. Further, the through-air dried web often has a three-dimensional pattern imparted by the through-air drying fabric. 
     While through-air drying results in softer and bulkier webs compared to manufacturing processes that rely upon compression to dewater the web, the process has limitations. To generate bulk, tissue makers often employ coarse through-air drying fabrics having a high degree of surface topography. As the wet web is molded to the high topography fabrics and dried it retains the shape of the fabric resulting in a dried tissue web having a high degree of surface topography. While such topography contributes to bulk it may impart the web with a rough surface and decrease the perceived softness of the web. Unfortunately, simply reducing the coarseness and topography of the through-air drying fabric to produce a smoother, less bulky web is not sufficient to improve softness because, when the surface topography is reduced the web becomes denser and fiber-fiber bonding is increased, which has a negative effect on softness. Thus, providing a through-air dried tissue web having good bulk and surface texture, while maintaining softness has proven to be elusive. 
     Unexpectedly, the present inventors have found a way to decouple the prior art relationship between surface texture, density and softness. Accordingly, it is now possible to improve the surface topography of tissue without encountering the concomitant loss of softness that occurs in the prior art. Further, in certain instance, the bulk of the tissue web may be maintained. Therefore, softness levels, previously unattainable at relatively high degrees of surface texture and sheet bulk, are possible with the present invention. 
     SUMMARY OF THE DISCLOSURE 
     Balancing of important tissue product properties such as softness, surface texture and bulk, while maintaining sufficient product strength and durability to withstand use, has traditionally been challenging for the tissue maker because many of the properties tend to be inversely related—improve one, at the detriment of another. For example, consumers often desire a tissue product that is soft, but also has surface topography to enhance wiping utility and provide the product with a visually appealing aesthetic. Providing sufficient texture, however, often results in a tissue with a high degree of surface topography and poor softness. Bulk is also an important property for the absorption capacity and hand-feel of tissue webs and products. Increasing the bulk of tissue webs and products, however, often comes at the expense of other properties such as surface texture. Traditionally the tissue maker has needed to resort to high topography papermaking fabrics to achieve high bulk. While increasing the caliper of the tissue web at a given basis weight, and therefore the sheet bulk, the use of high topography fabrics often impart the web with a three-dimensional surface that is not particularly smooth. 
     The present inventors have now successfully manufactured tissue products, particularly facial tissue products that may be folded and dispensed from a container as individual sheets, having good bulk and softness and a smooth surface, while having significantly improved strength. Surprisingly the increased strength does not detract from the softness, such that tissue products generally have a TS7 less than about 18, more preferably less than about 16, and still more preferably less than about 15, such as from about 10 to about 18 even at geometric mean tensile (GMT) strengths greater than about 1,200 g/3″. Previously it was believed that such softness levels were only obtainable by relatively weak and dense tissue products. 
     Accordingly, in one embodiment the present invention provides a multi-ply tissue product, such as a tissue product comprising two or more through-air dried tissue plies, the product having a geometric mean tensile (GMT) greater than about 1,200 g/3″, such as from about 1,200 to about 2,000 g/3″ and a TS7 less than about 20 and more preferably less than about 16. In certain instances, the inventive tissue products may have a relatively smooth surface, such as a TS750 less than about 15, such as from about 8 to about 15. 
     In still other embodiments the present invention provides a multi-ply creped, through-air dried tissue product comprising a first creped, through-air dried tissue ply and a second creped, through-air dried tissue ply, the product having a basis weight from about 35 to about 65 grams per square meter (gsm), a geometric mean tensile (GMT) from about 1,400 to about 1,800 g/3″ and a TS7 less than about 16. 
     In yet another embodiment the present invention provides a multi-ply through-air dried tissue product having a geometric mean tensile (GMT) from about 1,400 to about 1,800 g/3″, a TS7 from about 10 to about 18 and a TS750 from about 8 to about 15. In certain instances, the foregoing tissue product may have a sheet bulk greater than about 8.0 cc/g, such as from about 8.0 to about 12.0 cc/g. 
     In another embodiment the present invention provides a multi-ply tissue product comprising a first creped tissue ply having a first outer surface and a creping composition disposed thereon, a second creped tissue ply having a first outer surface and a creping composition, also referred to herein as a binder composition, disposed thereon, the first and second creped tissue plies plied together in facing arrangement such that the first outer surfaces face one another, the product having a GMT from about 1,400 to about 2,000 g/3″,″ and a TS7 less than about 15. In certain instances, the creping composition disposed on the first outer surfaces of the first and second plies may comprise latex polymer, and more preferably a non-crosslinked latex polymer, such as a vinyl acetate-ethylene latex polymer, and optionally an anti-blocking agent, such as a polysaccharide. 
     In still other embodiments, the present invention provides a method of making a tissue web comprising the steps of: (a) forming an aqueous suspension of fibers (b) depositing an aqueous suspension of fibers onto a forming fabric traveling at a first rate of speed to form a wet web; (c) dewatering the web to a consistency of about 20 percent or greater; (d) transferring the web to a through-air drying fabric and through-air drying the web to form a dried tissue web; (e) applying a latex polymer to the first outer surface of the dried tissue web in a pattern; (f) adhering the first outer surface of the dried tissue web to a rotary dryer, and (g) creping the tissue web from the rotary dryer. Preferably the resulting creped tissue ply has a basis weight from about 16 to about 30 gsm and has a TS7 less than about 20.0, more preferably less than about 18.0 and still more preferably less than about 16.0. 
     In certain instances, plies produced according to the proceeding method may be plied together to form a multi-ply tissue product, particularly facial tissue products that may be folded and dispensed from a container as individual sheets. When plying multiple plies together the individual plies may be brought into facing arrangement with one another such that the ply outer surface brought into contact with the Yankee dryer and having a creping composition disposed thereon may face one another such that the surface contacted by the user in-use is substantially free from the creping composition.

     While the TEA Index may vary, in certain instances tissue products prepared according to the present invention have a TEA Index of about 1.75 or greater, such as about 2.00 or greater, such as from about 1.75 to about 2.25. 
     As used herein, the term “Wet/Dry Ratio” refers to the ratio of the wet cross-machine direction (CD) tensile strength to the dry CD tensile strength. Wet and dry CD tensile are measured as set forth in the Test Methods section below. The Wet/Dry Ratio of inventive tissue products may vary depending on several factors such as, for example, the creping composition and the amount of wet strength additive, however, in certain instances the inventive tissue products may have a tissue products may have a Wet/Dry Ratio greater than about 0.20, such as greater than about 0.25, such as greater than about 0.30, such as from about 0.20 to about 0.35. 
     As used herein, the term “Slough” generally refers to the undesirable sloughing off of bits of the tissue web when rubbed and is generally measured as described in the Test Methods section below. Slough is generally reported in terms of mass, such as milligrams (mg). While the Slough of inventive tissue products may vary, in certain instances tissue products prepared according to the present invention have a Slough of about 2.00 mg or less, such as about 1.50 mg or less, such as about 1.00 or less, such as from about 0.50 to about 2.00 mg. 
     As used herein, the term “TS750” generally refers to the smoothness of a tissue product surface measured using an EMTEC Tissue Softness Analyzer (“Emtec TSA”) (Emtec Electronic GmbH, Leipzig, Germany) interfaced with a computer running Emtec TSA software (version 3.19 or equivalent). The units of the TS750 value are dB V 2  rms, however, TS750 values are often referred to herein without reference to units. Generally, the TS750 value is the magnitude of the peak occurring at a frequency between about 200 and 1,000 Hz, which is produced by vibration of the tissue product during the test procedure. Such vibrations are mainly caused by roughness and embossing. Generally, a lower TS750 value is indicative of a smoother surface. 
     As used herein, the term “TS7” generally refers to the softness of a tissue product surface measured using an EMTEC Tissue Softness Analyzer (“Emtec TSA”) (Emtec Electronic GmbH, Leipzig, Germany) interfaced with a computer running Emtec TSA software (version 3.19 or equivalent). The units of the TS7 are dB V 2  rms, however, TS7 values are often referred to herein without reference to units. Generally, the TS7 is the magnitude of the peak occurring at a frequency between 6 and 7 kHz which is produced by vibration of the tissue product during the test procedure. Generally, a peak in this frequency range having a lower amplitude, and hence a lower TS7 value, is indicative of a softer tissue product. 
     DETAILED DESCRIPTION OF THE DISCLOSURE 
     The present inventors have now surprisingly discovered tissue products, particularly facial tissue products that may be folded and dispensed from a container as individual sheets, having improved strength and durability without a significant decrease in softness or surface smoothness. Accordingly, in certain embodiments, the present invention provides tissue plies and products incorporating the same that have been manufactured by adhering the nascent tissue ply, also referred to herein as a web, to a rotating dryer, such as a Yankee dryer, and creping the web from the dryer to remove it. In particularly preferred embodiments a latex binder is used to adhere the nascent tissue web to the dryer surface and is transferred to the web surface once it is removed from the dryer by creping. 
     Creping the nascent web to remove it from the rotating dryer disrupts fiber-fiber bonding increasing softness and decreasing the stiffness of the web. Of particular advantage, it has been discovered that the softness of the web is increased without substantially reducing the strength. More particularly, it has been discovered that the process shifts the normal strength-softness curve so as to create webs having unique softness and strength properties. 
     Without being bound by any particular theory it is believed that he presence of a latex creping composition on at least one outer surface of the tissue ply provides the ply with improved durability and strength, without negatively affecting stiffness, softness or smoothness. Moreover, in certain instances, the process of the present invention also improves the fuzz-on-edge properties of the base web. In general, the fuzz-on-edge test measures the amount of fibers present on the surface of the web that are generally aligned in the z-direction. The degree of “fuzziness” of a web has also been measured in a test referred to as a “perimeter per edge length” test as described in European Application No. 0 539 703 which is incorporated herein by reference. A greater fuzz-on-edge generally indicates a softer web. It has been found that base webs made according to the present invention can have a fuzz-on-edge in an amount greater than 2.00 mm/mm, and particularly greater than 2.25 mm/mm. 
     In certain preferred embodiments a multi-ply tissue product may be constructed from individual inventive tissue plies to take advantage of the greater fuzz-on-edge by arranging the plies such that surface of the web contacted by the dyer, i.e., the Yankee side, is not contacted by the user in-use. For example, when plying multiple plies together the individual plies may be brought into facing arrangement such that the outer surface brought into contact with the Yankee dryer and having a creping composition disposed thereon face one another such that the outer surface of the product, which is contacted by the user in-use, is substantially free from the creping composition. 
     Not only do the inventive tissue products have improved surface properties that make them particularly well suited for use as facial tissues, they are also have improved strength and durability. For example, in certain embodiments, tissue products of the present invention have a GMT of about 1,200 g/3″ or greater, such as about 1,400 g/3″ or greater, such as about 1,500 g/3″ or greater, such as from about 1,200 about 2,000 g/3″, such as from about 1,400 to about 2,000 g/3″. In other embodiments, the tissue products may have a geometric mean tensile energy absorption of about 20 g·cm/cm 2  or greater, such as about 22 g·cm/cm 2  or greater, such as about 24 g·cm/cm 2  or greater, such as from about 20 to about 28 g·cm/cm 2 , such as from about 22 to about 26 g·cm/cm 2 . Accordingly, the tissue products may have a TEA Index of about 1.75 or greater, such as about 2.00 or greater, such as from about 1.75 to about 2.25. 
     While the inventive tissue products have good strength and durability, they are generally soft, smooth and flexible. For example, the tissue products generally have a TS7 less than about 20 and more preferably less than about 18 and still more preferably less than about 16. In certain instances, the inventive tissue products may have a relatively smooth surface, such as a TS750 less than about 15, such as from about 8 to about 15. In still other instances the products may have a Stiffness Index less than about 8.00, such as less than about 6.50, such as less than about 5.50, such as from about 3.00 to about 8.00, such as from about 4.00 to about 6.50. 
     A comparison of the strength, softness and smoothness of various commercial and inventive tissue products is shown in Table 1, below. In one particularly preferred embodiment the present invention provides a multi-ply, such as a two-ply, tissue product, comprising a first and second creped, through-air dried tissue ply comprising a plurality of wood pulp fibers and a latex creping composition disposed on at least one outer surface of the ply, wherein the tissue product has a GMT greater than about 1,200 g/3″ and more preferably greater than about 1,400 g/3″, a TS7 less than about 16 and a TS750 less than about 15, such as from about 8.0 to about 15.

     Generally the tissue products of the present invention have a basis weight of greater than about greater than about 30 gsm, such as greater than about 35 gsm, such as greater than about 40 gsm, such as from about 30 to about 80 gsm, such as from about 35 to about 60 gsm, such as from about 40 to about 55 gsm. At the foregoing basis weights the tissue products may have a bulk greater than about 8.0 cc/g, such as from about 8.0 to about 12.0 cc/g and more preferably from about 9.0 to about 12.0 cc/g. In a particularly preferred embodiment, the present invention provides a through-air dried tissue product comprising a plurality of pulp fibers and having a basis weight from about 35 to about 55 gsm and a sheet bulk from about 8.0 to about 12.0 cc/g. 
     In still other embodiments, the present disclosure provides tissue products having a high degree of stretch. For example, the products may have a geometric mean stretch (GM Stretch) of about 20 percent or greater, such as about 22 percent or greater, such as about 24 percent or greater, such as from about 20 to about 30 percent, such as from about 22 to about 28 percent. In other instances, the products may have improved cross-machine direction stretch (CD Stretch), such as a CD Stretch of about 15 percent or greater, such as about 18 percent or greater, such as from about 15 to about 22 percent, such as from about 16 to about 20 percent. 
     In yet other embodiments, the inventive tissue products may be flexible, such as having a geometric mean slope (GM Slope) less than about 10.0 kg, such as less than about 8.00 kg, such as less than about 6.00 kg, such as from about 5.00 to about 10.0 kg, such as from about 6.00 to about 8.00 kg. The foregoing modulus may be achieved at even relatively high degrees of tensile strength, such as a GMT of about 1,200 g/3″ or greater, such as about 1,400 g/3″ or greater. As a result, the inventive tissue products generally have as low degree of stiffness, measured as Stiffness Index, such as a Stiffness Index less than about 8.0, such as less than about 7.0, such as less than about 6.0, such as from about 3.0 to about 8.0, such as from about 4.0 to about 6.0. 
     The tissue products of the present invention are preferably wet-laid and comprise a plurality of fibers, such as cellulosic pulp fibers. In one example, the tissue products comprise a plurality of wood pulp fibers. In another example, the fibrous structure may comprise a plurality of non-wood pulp fibers, for example plant fibers, synthetic staple fibers, and mixtures thereof. Suitable cellulosic fibers for use in connection with this invention include secondary (recycled) papermaking fibers and virgin papermaking fibers in all proportions. Such fibers include, without limitation, hardwood and softwood kraft pulp fibers. 
     Non-limiting examples of processes for making fibrous structures include known wet-laid papermaking processes, for example through-air-dried papermaking processes. Such processes typically include steps of preparing a fiber composition in the form of a suspension in a medium, either wet, more specifically aqueous medium, or dry, more specifically gaseous, i.e. with air as medium. The aqueous medium used for wet-laid processes is oftentimes referred to as a fiber slurry. The fibrous slurry is then used to deposit a plurality of fibers onto a forming wire, fabric, or belt such that an embryonic fibrous structure is formed, after which drying and/or bonding the fibers together results in a tissue web. Further processing of the tissue web may be carried out such that a finished tissue product is formed. 
     In certain embodiments tissue products may be formed from one or more basesheets, which may comprise a single homogenous or blended layer, or be multi-layered. In those instances where the basesheet is multi-layered it may comprise, two, three, or more layers. For example, the basesheet may comprise three layers such as first and second outer layers and a middle layer disposed there between. The layers may comprise the same or different fiber types. For example, the first and second outer layers may comprise short, low coarseness wood pulp fibers, such as hardwood kraft pulp fibers, and the middle layer may comprise long, low coarseness wood pulp fibers, such as northern softwood kraft pulp fibers. 
     In those instances where the web comprises multiple layers, the relative weight percentage of each layer may vary. For example, the web may comprise first and second outer layers and a middle layer where the first outer layer comprises from about 25 to about 35 weight percent of the layered web, the middle layer comprises from about 30 to about 50 weight percent of the layered web and the second outer layer comprises from about 25 to about 35 weight percent of the layered web. 
     Multi-layered basesheets useful in the present invention may be formed using any number of different processes known in the art, such as the process disclosed in U.S. Pat. No. 5,129,988, the contents of which are incorporated herein in a manner consistent with the present disclosure. One process for a forming multi-layered basesheet is illustrated in  FIG.  1   . A dilute aqueous suspension of papermaking fibers is dispersed from a headbox  10  having an upper headbox wall  12  and a lower headbox wall  14  and first and second dividers  16 ,  18 . In this manner the headbox may be used to form a basesheet having outer layers  22 ,  24  and a middle layer  20 , where each of the layers may comprise the same or different papermaking fibers. 
     To form the multi-layered basesheet, an endless traveling forming fabric  26 , suitably supported and driven by rolls  28  and  30 , receives the layered papermaking stock issuing from headbox  10 . Once retained on fabric  26 , the layered fiber suspension passes water through the fabric as shown by the arrows  32 . Water removal is achieved by combinations of gravity, centrifugal force and vacuum suction depending on the forming configuration. 
     In certain embodiments the one or more layers of a multi-layered basesheet, such as the middle layer, may be formed without a substantial amount of inner fiber-to-fiber bond strength. In this regard, the fiber furnish used to form a given layer can be treated with a chemical debonding agent. The debonding agent can be added to the fiber slurry during the pulping process or can be added directly the fiber slurry prior to the headbox. Suitable debonding agents that may be used in the present invention include cationic debonding agents, particularly quaternary ammonium compounds, mixtures of quaternary ammonium compounds with polyhydroxy compounds, and modified polysiloxanes. 
     Suitable cationic debonding agents include, for example, fatty dialkyl quaternary amine salts, mono fatty alkyl tertiary amine salts, primary amine salts, imidazoline quaternary salts and unsaturated fatty alkyl amine salts. Other suitable debonding agents are disclosed in U.S. Pat. No. 5,529,665, the contents of which are incorporated herein in a manner consistent with the present disclosure. In one embodiment, the debonding agent used in the process of the present invention is an organic quaternary ammonium chloride, such as those available under the tradename ProSoft™ (Solenis, Wilmington, Del.). The debonding agent can be added to the fiber slurry in an amount of from about 1.0 kg per metric tonne to about 15 kg per metric tonne of fibers present within the slurry. 
     Particularly useful quaternary ammonium debonders include imidazoline quaternary ammonium debonders, such as oleyl-imidazoline quaternaries, dialkyl dimethyl quaternary debonders, ester quaternary debonders, diamidoamine quaternary debonders, and the like. The imidazoline-based debonding agent can be added in an amount of between 1.0 to about 10 kg per metric tonne. 
     In other embodiments, a layer or other portion of the basesheet, including the entire basesheet, may optionally include wet or dry strength agents. As used herein, “wet strength agents” are materials used to immobilize the bonds between fibers in the wet state. Any material that when added to the tissue web at an effective level results in providing the basesheet with a wet geometric tensile strength:dry geometric tensile strength ratio in excess of 0.1 will, for purposes of this invention, be termed a wet strength agent. 
     Particularly preferred wet strength agents are permanent wet strength agents. Particularly preferred wet strength agents are water-soluble, cationic materials, particularly those that undergo a cross-linking or other curing reactions after they have been deposited on, within, or among the papermaking fibers. Of particular utility are the various polyamide-epichlorohydrin resins. These materials are low molecular weight polymers provided with reactive functional groups such as amino, epoxy, and azetidinium groups. Polyamide-epichorohydrin resins sold under the tradename Kymene by Ashland, Inc. of Wilmington, Del., are particularly useful in this invention. 
     In other instances, the basesheet may optionally include a dry strength additive, such as carboxymethyl cellulose resins, starch based resins, and mixtures thereof. Particularly preferred dry strength additives are cationic starches, and mixtures of cationic and anionic starches. In certain instances, the dry strength agent may comprise a commercially available modified starch such as marketed under the tradename RediBOND™ (Ingredion, Westchester, IL) or a commercially available carboxymethyl cellulose resin such as those marketed under the tradename Aqualon™ (Ashland LLC, Bridgewater, N.J.). 
     The amount of wet strength agent or dry strength added to the pulp fibers can be at least about 0.1 dry weight percent, more specifically about 0.2 dry weight percent or greater, and still more specifically from about 0.1 to about 3 dry weight percent, based on the dry weight of the fibers. 
     Tissue basesheets useful in forming tissue products of the present invention are preferably formed by a through-air drying (TAD) manufacturing process. In particularly preferred embodiments the tissue product is manufactured by a creped through-air dried (CTAD) process or uncreped through-air dried (UCTAD) process. With reference now to  FIG.  2   , a method for making through-air dried paper sheets is illustrated. Shown is a twin wire former having a papermaking headbox  34 , such as a layered headbox, which injects or deposits a stream  36  of an aqueous suspension of papermaking fibers onto the forming fabric  38  positioned on a forming roll  39 . The forming fabric serves to support and carry the newly-formed wet web downstream in the process as the web is partially dewatered to a consistency of about 10 dry weight percent. Additional dewatering of the wet web can be carried out, such as by vacuum suction, while the wet web is supported by the forming fabric. 
     The wet web is then transferred from the forming fabric to a transfer fabric  40 . In one embodiment, the transfer fabric can be traveling at a slower speed than the forming fabric in order to impart increased stretch into the web. This is commonly referred to as a “rush” transfer. The relative speed difference between the two fabrics can be from 0 to 60 percent, more specifically from about 15 to 45 percent. Transfer is preferably carried out with the assistance of a vacuum shoe  42  such that the forming fabric and the transfer fabric simultaneously converge and diverge at the leading edge of the vacuum slot. 
     The web is then transferred from the transfer fabric to the through-air drying fabric  44  with the aid of a vacuum transfer roll  46  or a vacuum transfer shoe, optionally again using a fixed gap transfer as previously described. The through-air drying fabric can be traveling at about the same speed or a different speed relative to the transfer fabric. If desired, the through-air drying fabric can be run at a slower speed to further enhance stretch. Transfer can be carried out with vacuum assistance to ensure deformation of the sheet to conform to the through-air drying fabric, thus yielding desired bulk and imparting the web with a three-dimensional topographical pattern. Suitable through-air drying fabrics are described, for example, in U.S. Pat. Nos. 6,998,024, 7,611,607 and 10,161,084, the contents of which are incorporated herein by reference in a manner consistent with the present disclosure. 
     In one embodiment, the through-air drying fabric comprises a single layer fabric woven from shute and warp filaments. In certain instances, the shute filaments may comprise two or more different diameters and may be interwoven with the warp filaments so as to form a textured sheet contacting surface having substantially continuous machine-direction ripples separated by valleys. In other instances, the woven fabric may comprise a plurality of substantially continuous machine-direction ripples formed of multiple warp strands grouped together and supported by multiple shute strands of two or more diameters. During drying, the web can be macroscopically arranged to conform to the surface of the through-air drying fabric and form a textured, three-dimensional surface. 
     The side of the web contacting the through-air drying fabric is typically referred to as the “fabric side” of the paper web. The fabric side of the paper web, as described above, may have a shape that conforms to the surface of the through-air drying fabric after the fabric is dried in the through-air dryer. The opposite side of the paper web, on the other hand, is typically referred to as the “air side.” 
     The level of vacuum used for the web transfers can be from about 3 to about 15 inches of mercury (75 to about 380 millimeters of mercury), preferably about 5 inches (125 millimeters) of mercury. The vacuum shoe (negative pressure) can be supplemented or replaced by the use of positive pressure from the opposite side of the web to blow the web onto the next fabric in addition to or as a replacement for sucking it onto the next fabric with vacuum. Also, a vacuum roll or rolls can be used to replace the vacuum shoe(s). 
     While supported by the through-air drying fabric, the web is dried to a consistency of about 94 percent or greater by the through-air dryer  48  and thereafter transferred to a carrier fabric  50 . The dried basesheet  52  is transported to the reel  54  using carrier fabric  50  and an optional carrier fabric  56 . An optional pressurized turning roll  58  can be used to facilitate transfer of the web from carrier fabric  50  to fabric  56 . 
     In one embodiment, the reel  54  shown in  FIG.  2    can run at a speed slower than the fabric  56  in a rush transfer process for building bulk into the paper web  52 . For instance, the relative speed difference between the reel and the fabric can be from about 5 to about 25 percent and, particularly from about 12 to about 14 percent. Rush transfer at the reel can occur either alone or in conjunction with a rush transfer process upstream, such as between the forming fabric and the transfer fabric. 
     Once the web is formed, a binder composition, also referred to herein as a creping composition, is applied to at least one side of the web. In this manner, the present invention provides a tissue product comprising a web having first and second outer surfaces, wherein at least one outer surface comprises a topically-applied binder, particularly a binder applied in a network. As used herein, the term “network” is used to describe any binder pattern that serves to bond the sheet together. The pattern can be regular or irregular and can be continuous or discontinuous. 
     With reference now to  FIG.  3   , one embodiment of applying a binder material to one outer surface of a web is illustrated. Shown is paper web  52  passing through a binder material application station  65 . Station  65  includes a transfer roll  67  in contact with a rotogravure roll  68 , which is in communication with a reservoir  69  containing a suitable binder  70 . Although gravure printing of the binder is illustrated, other means of applying the binder material can also be used, such as foam application, spray application, flexographic printing, or digital printing methods, such as ink jet printing, and the like. The rotogravure roll  68  applies binder material  70  to one side of the web  52  in a pre-selected pattern. 
       FIGS.  4 - 6    illustrate several different print patterns that may be used for applying a binder material to a basesheet in accordance with this invention. As illustrated in  FIG.  4   , the pattern may comprise a succession of discrete dots. In one embodiment, for instance, the dots can be spaced so that there are approximately from about 25 to about 35 dots per inch (25.4 mm) in the machine direction and/or the cross-machine direction. The dots can have a diameter, for example, of from about 0.01 inch (0.25 mm) to about 0.03 inch (0.76 mm). In one particular embodiment, the dots can have a diameter of about 0.02 inch (0.51 mm) and can be present in the pattern so that approximately 28 dots per inch (25.4 mm) extend in both the machine direction and the cross-machine direction. Besides dots, various other discrete shapes such as elongated ovals or rectangles can also be used when printing the binder material onto the sheet. 
       FIG.  5    shows a print pattern in which the binder material print pattern is made up of discrete multiple deposits that are each comprised of three elongated hexagons. In one embodiment, each hexagon can be about 0.02 inch (0.51 mm) long and can have a width of about 0.006 inch (0.15 mm). Approximately 35 to 40 deposits per inch (25.4 mm) can be spaced in the machine direction and the cross-machine direction. 
       FIG.  6    illustrates an alternative binder material pattern in which the binder material is printed onto the sheet in a reticulated pattern. The dimensions are similar to those of the dot pattern of  FIG.  4   . Reticulated patterns, which provide a continuous network of binder material, may result in relatively greater sheet strength than comparable patterns of discrete elements, such as the dot pattern of  FIG.  4   . It will be appreciated that many other patterns, in addition to those illustrated above, can also be used depending on the desired properties of the final product. 
     With reference again to  FIG.  3   , after the binder material  70  is applied, the sheet  52  is adhered to a heated creping cylinder  75  by a press roll  76 . The sheet  52  is carried on the surface of the heated creping cylinder  75  for a distance and then removed therefrom by the action of a creping blade  78 . The creping blade  78  performs a controlled pattern creping operation on the side of the sheet  52  to which the binder material  70  was applied. 
     Once creped, the sheet  52  is pulled through an optional drying station  80 . The drying station can include any form of a heating unit, such as an oven energized by infrared heat, microwave energy, hot air, or the like. Alternatively, the drying station may comprise other drying methods such as photo-curing, UV-curing, corona discharge treatment, electron beam curing, curing with reactive gas, curing with heated air such as through-air heating or impingement jet heating, infrared heating, contact heating, inductive heating, microwave or RF heating, and the like. Depending upon the binder material selected, however, drying station  80  may not be needed. Once passed through the drying station  80 , the sheet  52  can be wound into a roll of material or product  85 . 
     In certain instances, the binder composition may be selected not only to assist in creping the web but also for improving one or more physical properties of the web such as, for example, dry strength, wet strength, stretchability, and tear resistance. Particular binder compositions that may be used in the present invention include latex compositions. The latex composition may comprise a non-carboxylated latex emulsion or a carboxyl-functional latex emulsion polymer. Non-carboxylated latex emulsions useful in the present invention may comprise an aqueous polymer dispersion of vinyl acetate and ethylene. Suitable non-carboxylated latex emulsions include vinyl acetate and ethylene emulsions such as Vinnapas™ EZ123, commercially available from Wacker Polymers, LP (Allentown, PA). In other instances, the binder composition may comprise a carboxyl-functional latex polymer such as Vinnapas™ EP1133, commercially available from Wacker Polymers, LP (Allentown, PA). 
     Latex polymers useful in the present invention may comprise unsaturated monomers, such as vinyl acetate and ethylene monomers, polymerized in the presence of surfactants and initiators to produce emulsion-polymerized polymer particles. Unsaturated monomers contain carbon-to-carbon double bond unsaturation and generally include vinyl monomers, styrenic monomers, acrylic monomers, allylic monomers, acrylamide monomers, as well as carboxyl functional monomers. Vinyl monomers include vinyl esters such as vinyl acetate, vinyl propionate and similar vinyl lower alkyl esters, vinyl halides, vinyl aromatic hydrocarbons such as styrene and substituted styrenes, vinyl aliphatic monomers such as alpha olefins and conjugated dienes, and vinyl alkyl ethers such as methyl vinyl ether and similar vinyl lower alkyl ethers. Acrylic monomers include lower alkyl esters of acrylic or methacrylic acid having an alkyl ester chain from one to twelve carbon atoms as well as aromatic derivatives of acrylic and methacrylic acid. Useful acrylic monomers include, for instance, methyl, ethyl, butyl, and propyl acrylates and methacrylates, 2-ethyl hexyl acrylate and methacrylate, cyclohexyl, decyl, and isodecyl acrylates and methacrylates, and similar various acrylates and methacrylates. 
     In certain embodiments the latex polymers may comprise a carboxyl-functional latex polymer comprising copolymerized carboxyl-functional monomers such as acrylic and methacrylic acids, fumaric or maleic or similar unsaturated dicarboxylic acids, where the preferred carboxyl monomers are acrylic and methacrylic acid. In certain instances, the carboxyl-functional latex polymers may comprise by weight from about 1 to about 50 percent copolymerized carboxyl monomers with the balance being other copdymerized ethylene monomers. Suitable carboxyl-functional latex polymers include carboxylated vinyl acetate-ethylene polymer emulsions such as Vinnapas™ EP1133, commercially available from Wacker Polymers, LP (Allentown, PA). 
     In certain instances, the binder composition may optionally contain an anti-blocking additive designed to modify the surface chemistry or characteristics of the binder film on the basesheet. Suitable anti-blocking additives generally do not react chemically with the binder and may include: 1) surfactants, including anionic surfactants such as sodium and potassium salts of stearic, palmitic, oleic, lauric, and tall oil fatty acids, and non-ionic surfactants such as polyoxyethylene glycols reacted to a lyophilic compound; 2) non-reactive additives, such as silicones, waxes, oils, designed to modify the surface chemistry of at least one outer surface of the web to reduce blocking; and 3) soluble or insoluble crystals, such as sugars, talc, clay, and the like, designed to reside on the surface of the binder film and thus reduce its propensity to cause blocking to an adjacent web surface. The amount of the anti-blocking additive in the binder composition, relative to the amount of carboxyl-functional latex emulsion polymer on a weight percent solids basis, can be from about 1 to about 25 percent, more specifically from about 5 to about 20 percent and more specifically from about 10 to about 15 percent. 
     Accordingly, in certain embodiments, binders useful in the present invention may consist essentially of a non-crosslinked latex polymer, such as a vinyl acetate-ethylene latex polymer, and optionally an anti-blocking agent, such as a polysaccharide, to prevent blocking upon drying of the tissue web. 
     In certain preferred embodiments it may be desirable to form the inventive tissue products using a binder that is substantially free from polyfunctional aldehydes, such as glyoxalated polyacrylamide and glyoxal, and azetidinium-functional cross-linking polymers, such as polyamide-epichlorohydrin (PAE) resins and polyamide-polyamine-epichlorohydrin (PPE) resins. Thus, in a preferred embodiment the latex polymer, which may comprise either a non-carboxylated or a carboxylated latex polymer, is not subjected to crosslinking before or after it is applied to the tissue web. 
     While in certain embodiments it may be desirable that the latex polymer is not crosslinked before or after it is applied to the tissue web, the invention is not so limited. In other embodiments, the binder may comprise a carboxyl-functional latex emulsion polymer that has been reacted with an azetidinium-functional cross-linking polymer, such as a polyamide-epichlorohydrin (PAE) resins or a polyamide-polyamine-epichlorohydrin (PPE) resin. Cross-linked carboxyl-functional latex suitable for use as a binder in the manufacture of inventive tissue products are disclosed in U.S. Pat. No. 7,297,231, the contents of which are incorporated herein in a manner consistent with the present disclosure. 
     In certain instances, the binder composition may be applied to the base web in a preselected pattern. In one embodiment, for instance, the binder composition can be applied to the web in a reticular pattern, such that the pattern is interconnected forming a net-like design or grid on the surface. In other embodiments the binder composition may be applied to the web in a pattern that represents a succession of discrete shapes. For example, the binder composition may be applied in a pattern of discrete dots. Despite consisting of discrete shapes, such patterns provide the desired physical properties without covering a substantial portion of the surface area of the web. 
     In certain preferred embodiments the binder composition is applied to only one side of the web so as to cover from about 15 to about 75 percent of the surface area of the web. More particularly, in most applications, the binder composition will cover from about 20 to about 60 percent of the surface area of the web. The total amount of binder composition applied to the web can be in the range of from about 1 to about 25 percent by weight, such as from about 2 to about 10 percent by weight, based upon the total weight of the web. 
     In the embodiment shown in  FIG.  3    only one side of the web is treated with a binder composition leaving an untreated side. Leaving one side of the tissue web untreated may provide various benefits and advantages under some circumstances. For instance, the untreated side may increase the ability of the tissue web to absorb liquids faster. Further, the untreated side may have a greater texture than if the side were treated with a binder composition. 
     Further, the process illustrated in  FIG.  3    represents only one possible method for applying a binder composition to the web. Other applications methods may be suitable for applying a binder composition to the web. For example, various printing methods can be used to print the binder composition onto the web depending upon the particular application. Such printing methods can include direct gravure printing, offset gravure printing, or flexographic printing. 
     In addition to having a binder composition applied to one or more outer surfaces, as described above, the tissue product may be subjected to additional converting, such as calendering, treatment with a softening composition, embossing, slitting, winding and/or folding. 
     In certain embodiments tissue products of the present invention may be treated with a softening composition to improve the hand feel or deliver a benefit to the end user. As used herein, the term “softening composition” refers to any chemical composition which improves the tactile sensation perceived by the end user who holds a particular tissue product and rubs it across the skin. Suitable softening compositions include, for example, basic waxes such as paraffin and beeswax and oils such as mineral oil and silicone oil as well as petrolatum and more complex lubricants and emollients such as quaternary ammonium compounds with long alkyl chains, functional silicones, fatty acids, fatty alcohols and fatty esters. 
     Accordingly, in one embodiment the tissue products of the present invention may be treated with a softening composition comprising one or more oils, such as mineral oil, waxes, such as paraffin, or plant extracts, such as chamomile and aloe vera, such as disclosed in U.S. Pat. Nos. 5,885,697 and 5,525,345, the contents of which are incorporated herein in a manner consistent with the present disclosure. 
     In other embodiments the tissue products may be treated with a softening composition comprising a polysiloxane, and more preferably with a composition comprising an amino-functional polysiloxane, a surfactant and optionally a skin conditioning agent, such as the compositions disclosed in U.S. Publication No. 2006/0130989, the contents of which are incorporated herein in a manner consistent with the present disclosure. In certain preferred embodiments the polysiloxane is an amino-functional polysiloxane, the surfactant is an ethoxylated alcohol or an ethoxylated propoxylated alcohol and the skin conditioning agent is vitamin E and/or aloe vera. 
     All of the foregoing softening compositions may optionally contain a beneficial agent, such as a skin conditioning agent or a humectant, which may be provided in an amount ranging from about 0.01 to about 5 percent by weight of the composition. Suitable humectants include lactic acid and its salts, sugars, ethoxylated glycerin, ethoxylated lanolin, corn syrup, hydrolyzed starch hydrolysate, urea, and sorbitol. Suitable skin conditioning agents include allantoin, kaolin, zinc oxide, aloe vera, vitamin E, petrolatum and lanolin. Again, the foregoing additives are generally complementary to the softening compositions of the present invention and generally do not significantly and adversely affect important tissue product properties, such as strength or absorbency of the tissue product, or negatively affect the softening provided by the softening compositions of the present invention. 
     The foregoing softening compositions are generally applied to one or two outermost surfaces of a dry tissue web and more preferably a creped tissue web having a binding composition disposed on at least one outer surface. The method by which the softening composition is applied to the tissue sheet may be accomplished by any method known in the art. For example, in one embodiment the composition may be applied by contact printing methods such as gravure, offset gravure, flexographic printing, and the like. The contact printing methods often enable topical application of the composition to the tissue sheet. In other embodiments the softening composition may be applied to the tissue web by non-contact printing methods such as ink jet printing, digital printing of any kind, and the like. 
     In certain preferred embodiments the softening composition may be prepared as an aqueous solution and applied to the web by spraying or rotogravure printing. It is believed in this manner that tactile softness of the tissue sheet and resulting tissue products may be improved due to presence of the softening composition on the surface of the tissue product. When applied as an aqueous solution, the softening composition may comprise from about 50 to about 90 weight percent, by weight of the composition, water and more preferably from about 60 to about 80 percent. 
     In other instances, the basesheets prepared as described above may be subjected to plying to produce the inventive tissue products. For example, the tissue products of the present invention may be provided as multi-ply products comprising two or more plies, such as two, three or four plies, where the plies are mechanically joined together by crimping or the like. When plying multiple plies together the individual plies may be brought into facing arrangement with one another such that the ply outer surface brought into contact with the Yankee dryer and having a creping composition disposed thereon may face one another such that the surface contacted by the user in-use is substantially free from the creping composition. The product may also be cut and into individual sheets, folded and packaged in a carton to be dispensed as individual sheets. 
     Test Methods 
     Basis Weight 
     Prior to testing, all samples are conditioned under TAPPI conditions (23±1° C. and 50±2 percent relative humidity) for a minimum of 4 hours. Basis weight of sample is measured by selecting twelve (12) products (also referred to as sheets) of the sample and making two (2) stacks of six (6) sheets. In the event the sample consists of perforated sheets of bath or towel tissue, the perforations must be aligned on the same side when stacking the usable units. A precision cutter is used to cut each stack into exactly 10.16×10.16 cm (4.0×4.0 inch) squares. The two stacks of cut squares are combined to make a basis weight pad of twelve (12) squares thick. The basis weight pad is then weighed on a top loading balance with a minimum resolution of 0.01 grams. The top loading balance must be protected from air drafts and other disturbances using a draft shield. Weights are recorded when the readings on the top loading balance become constant. The mass of the sample (grams) per unit area (square meters) is calculated and reported as the basis weight, having units of grams per square meter (gsm). 
     Caliper 
     Caliper is measured in accordance with TAPPI test methods Test Method T 580 μm-12 “Thickness (caliper) of towel, tissue, napkin and facial products.” The micrometer used for carrying out caliper measurements is an Emveco 200-A Tissue Caliper Tester (Emveco, Inc., Newberg, OR). The micrometer has a load of 2 kilopascals, a pressure foot area of 2,500 square millimeters, a pressure foot diameter of 56.42 millimeters, a dwell time of 3 seconds and a lowering rate of 0.8 millimeters per second. 
     Slough 
     The Slough test provides a quantitative measure of the abrasion resistance of a tissue sample. More specifically, the test measures the resistance of a material to an abrasive action when the material is subjected to a horizontally reciprocating surface abrader. The equipment used to measure Slough is similar to that described in U.S. Pat. No. 6,808,595, the disclosure of which is incorporated by reference herein in a manner consistent with the present invention. The abrading spindle consists of a stainless-steel rod, approximately 1.25 cm (0.495 inches) in diameter and 15.25 cm (6 inches) in length. The abrasive portion of the abrading spindle is 10.8 cm (4.25 inches) in length and consists 18/22 abrasion coating (commercially available from Superabrasives, Inc., Wixom, Mich.) applied around the entire circumference of the abrading spindle. The abrading spindle is mounted perpendicularly to the face of the instrument such that the abrasive portion of the abrading spindle extends out its entire distance from the face of the instrument. On each side of the abrading spindle is located a pair of damps, one movable and one fixed. The damps are spaced 10 cm (4 inches) apart and centered about the abrading spindle. The movable clamp (weighing approximately 21 grams) is allowed to slide freely in the vertical direction, the weight of the movable clamp providing the means for ensuring a constant is tension of the tissue sheet sample over the surface of the abrading spindle. Instruments for measuring Slough according to the present invention are available at Accelerated Analytical Laboratories (Milwaukee, Wis.). 
     Prior to testing, any loose dust should be removed from the abrading spindle with compressed air. If other debris is present on the abrading spindle, the spindle may be washed in warm water and dish detergent, rinsed with distilled water and dried in an oven. In the event the abrading spindle is washed prior to use, care must be taken to ensure that all cleaning solution is rinsed from the abrading spindle and that it is completely dry before use. 
     Samples are conditioned under TAPPI conditions (23±1° C. and 50±2 percent relative humidity) for a minimum of 4 hours prior to testing. For perforated bath tissue products, samples are first prepared by unrolling the tissue and separating into lengths of 3 sheets. Using a precision cutter, such as a JDC-3 cutter (commercially available from Thwing-Albert Instrument Company, Philadelphia, Pa.), each sample is cut to a size of 177.8±13 mm (7.0±0.5 inches) in the machine direction (MD) by 76.2±1 mm (3.0±0.04 inches) in the cross-machine direction (CD). When cutting perforated bath tissue products, as illustrated in  FIG.  7   , the sample  100  is cut such that a first end  102  extends 25.4 mm (1 inch) beyond a first line of perforations  105  and a second end  104  extends 50.8 mm (2 inches) beyond a second line of perforations  107  to ensure that the spindle does not abrade over the perforations  105 ,  107  in the sample  100 . 
     When testing rolled and perforated bath tissue products testing should be done on the outside surface of the roll as it is unwound. Generally rolled and perforated bath tissue products are not separated. into individual plies prior to testing and the outer surface of the product, as it is unwound from the roll, is tested. When testing folded facial tissue products, the product is separated into individual plies and the outward facing side of one of the outer plies is tested. 
     Each tissue sheet sample is weighed to the nearest 0.1 mg. One end of the tissue sheet sample is clamped to the fixed clamp, the sample is then loosely draped over the abrading spindle and clamped into the sliding clamp. The entire width of the sample should be in contact with the abrading spindle. The sliding clamp is then allowed to fall providing constant tension across the abrading spindle. The entire width of the tissue sheet sample should be in contact with the abrading spindle. 
     Once the sample is secured the test begins by moving the abrading spindle back and forth at an approximate 15-degree angle from the centered vertical centerline in a reciprocal horizontal motion against the tissue sample for 40 cycles at a speed of 73.5±0.5 cycles per minute. As the spindle cycles, it is also rotated counterclockwise (when looking at the front of the instrument) at an approximate speed of 5 RPMs. Once the 40 cycles are complete, the tissue sample is removed from the jaws with the fingertips and both sides of the sample are blown with air having a flow rate of approximately 3.4 scfm for approximately 13 seconds to remove debris. 
     The tissue sheet sample is then weighed to the nearest 0.1 mg and the weight loss calculated. The difference between the initial weight and the weight after testing is the amount of Slough. Ten samples are tested and the average weight loss value in milligrams (mg) is recorded, which is the Slough value for the sample. 
     Tensile 
     Tensile testing is conducted on a tensile testing machine maintaining a constant rate of elongation and the width of each specimen tested is 3 inches. Testing is conducted under TAPPI conditions. Prior to testing samples are conditioned under TAPPI conditions (23±1° C. and 50±2 percent relative humidity) for at least 4 hours and then cutting a 3±0.05 inches (76.2±1.3 mm) wide strip in either the machine direction (MD) or cross-machine direction (CD) orientation using a JDC Precision Sample Cutter (Thwing-Albert Instrument Company, Philadelphia, Pa., Model No. JDC 3-10, Serial No. 37333) or equivalent. The instrument used for measuring tensile strengths was an MTS Systems Sintech 11S, Serial No. 6233. The data acquisition software was MTS TestWorks® for Windows Ver. 3.10 (MTS Systems Corp., Research Triangle Park, NC). The load cell was selected from either a 50 Newton or 100 Newton maximum, depending on the strength of the sample being tested, such that the majority of peak load values fall between 10 to 90 percent of the load cell&#39;s full-scale value. The gauge length between jaws was 4±0.04 inches (101.6±1 mm) for facial tissue and towels and 2±0.02 inches (50.8±0.5 mm) for bath tissue. The crosshead speed was 10±0.4 inches/min (254±1 mm/min), and the break sensitivity was set at 65 percent. The sample was placed in the jaws of the instrument, centered both vertically and horizontally. The test was then started and ended when the specimen broke. The peak load was recorded as either the “MD tensile strength” or the “CD tensile strength” of the specimen depending on direction of the sample being tested. Ten representative specimens were tested for each product or sheet and the arithmetic average of all individual specimen tests was recorded as the appropriate MD or CD tensile strength having units of grams per three inches (g/3″). Tensile energy absorbed (TEA) and slope are also calculated by the tensile tester. TEA is reported in units of g·cm/cm 2  and slope is recorded in units of kilograms (kg). Both TEA and Slope are directionally dependent and thus MD and CD directions are measured independently. 
     All products were tested in their product forms without separating into individual plies. For example, a 2-ply product was tested as two plies and recorded as such. In the tensile properties of basesheets were measured, the number of plies used varied depending on the intended end use. For example, if the basesheet was intended to be used for 2-ply product, two plies of basesheet were combined and tested. 
     Wet CD Tensile 
     Wet tensile strength measurements are measured in the same manner as described for dry tensile above, but after the center portion of the previously conditioned sample strip has been saturated with distilled water immediately prior to loading the specimen into the tensile test equipment. Sample wetting is performed by first laying a single test strip onto a piece of blotter paper (Fiber Mark, Reliance Basis 120). A pad is then used to wet the sample strip prior to testing. The pad is a green, Scotch-Brite brand (3M) general purpose commercial scrubbing pad. To prepare the pad for testing, a full-size pad is cut approximately 2.5 inches long by 4 inches wide. A piece of masking tape is wrapped around one of the 4 inch long edges. The taped side then becomes the“top” edge of the wetting pad. To wet a tensile strip, the tester holds the top edge of the pad and dips the bottom edge in approximately 0.25 inches of distilled water located in a wetting pan. After the end of the pad has been saturated with water, the pad is then taken from the wetting pan and the excess water is removed from the pad by lightly tapping the wet edge three times across a wire mesh screen. The wet edge of the pad is then gently placed across the sample, parallel to the width of the sample, in the approximate center of the sample strip. The pad is held in place for approximately one second and then removed and placed back into the wetting pan. The wet sample is then immediately inserted into the tensile grips, so the wetted area is approximately centered between the upper and lower grips. The test strip should be centered both horizontally and vertically between the grips. (It should be noted that if any of the wetted portion comes into contact with the grip faces, the specimen must be discarded, and the jaws dried off before resuming testing.) The tensile test is then performed, and the peak load recorded as the wet CD tensile strength of this specimen. As with the dry CD tensile test, the characterization of a product is determined by the average of ten representative sample measurements. 
     Tissue Softness Analyzer 
     Softness and surface smoothness were measured using an EMTEC Tissue Softness Analyzer (“TSA”) (Emtec Electronic GmbH, Leipzig, Germany). The TSA comprises a rotor with vertical blades which rotate on the tissue sample applying a defined contact pressure. The blades are pressed against the sample with a load of 100 mN and the rotational speed of the blades is two revolutions per second. Contact between the vertical blades and the tissue sample creates vibrations, which are sensed by a vibration sensor. The sensor transmits a signal to a PC for processing and display. The signal is displayed as a frequency spectrum. The frequency spectrum is analyzed by the associated TSA software to determine the amplitude of the frequency peak occurring in the range between 200 to 1000 Hz. This peak is generally referred to as the TS750 value (having units of dB V 2  rms) and represents the surface smoothness of the tissue sample. A high amplitude peak correlates to a rougher surface, while a low amplitude peak correlates a smoother surface. A further peak in the frequency range between 6 and 7 kHZ represents the softness of the sample. The peak in the frequency range between 6 and 7 kHZ is herein referred to as the TS7 value (having units of dB V 2  rms). The lower the amplitude of the peak occurring between 6 and 7 kHZ, the softer the sample. 
     Tissue product samples were prepared by cutting a circular sample having a diameter of 112.8 mm. All samples were allowed to equilibrate at TAPPI conditions for at least 24 hours prior to completing the TSA testing. After conditioning each sample was tested as—is, i.e., multi-ply products were tested without separating the sample into individual plies. The sample is secured, and the measurements are started via the PC. The PC records, processes and stores all of the data according to standard TSA protocol. The reported TS750 and TS7 values are the average of five replicates, each one with a new sample. 
     Fuzz-on-Edge 
     Fuzz-on-Edge measures the amount of fibers that protrude from the surface of a fibrous material. The measurement is performed using image analysis to detect and then measure the total perimeter of protruding surface fibers observed when the material in question is wrapped over an “edge” to allow the fibers to be viewed from the side using transmitted light. An image analysis algorithm was developed to detect and measure the perimeter length (mm) of the fibers per edge length (mm) of material, where the perimeter length is defined as the total length of the boundaries of all of the protruding fibers (i.e. Perimeter/Edge Length or PR/EL for short). For example, an edge along the majority of the length of a fibrous material (e.g. facial tissue) can be measured by acquiring and analyzing multiple, adjacent fields-of-view to arrive at a single PR/EL value, Typically, several such material specimens are analyzed for a sample to arrive at a mean PR/EL value. 
     The Fuzz on Edge was determined using the method described in U.S. Publication No. 2010/0155004, the contents of which are incorporated herein in a manner consistent with the present disclosure, with the following modifications: A Leica DFX-300 camera (Leica Microsystems Ltd, Heerbrugg, Switzerland) is mounted on a Polaroid MP-4 Land Camera (Polaroid Resource Center, Cambridge, Mass.) standard support, The support is attached to a Kreonite macro-viewer (Kreonite Inc., Wichita, Kans.). An auto-stage, DCI Model HM-1212, is placed on the upper surface of Kreonite macro-viewer and the sample mounting apparatus was placed atop the auto-stage (commercially available from Design Components Incorporated, Franklin, MA). The auto-stage is used to move the sample in order to obtain 15 separate and distinct, non-overlapping images from the specimen. The sample mounting apparatus is placed on the auto macro-stage (DCI 12×12 inch) of an image analysis system controlled by Leica Microsystems QWIN Pro software, under the optical axis of an 80-mm AF Micro Nikon lens (Nikon Corp., Japan) fitted with a 20-mm extension tube. The lens focus is adjusted to provide the maximum magnification and the camera position on the Polaroid MP-4 support is adjusted to provide optimum focus of the tissue edge. The sample is Illuminated from beneath the auto-stage using a Chroma Pro 45 (Circle 2, Inc., Tempe, AZ). The Chroma Pro settings are such that the light is ‘white’ and not filtered in any way to bias the light&#39;s spectral output. The Chroma Pro may be connected to a POWERSTAT Variable Auto-transformer, type 3P 117C (commercially available from Superior Electric, Co., Bristol, CT). The auto-transformer is used to adjust the Chroma Pro&#39;s illumination level. 
     EXAMPLE 
     Example 1 
     Basesheets were made using a through-air dried papermaking process commonly referred to as “uncreped through-air dried” (“UCTAD”) and generally described in U.S. Pat. No. 5,607,551, the contents of which are incorporated herein in a manner consistent with the present disclosure. Basesheets were prepared using a three-layered headbox to form a web having a first outer layer, also referred to as the fabric or fabric contacting layer, a middle layer, and a second outer layer, also referred to the air contacting or air layer.  Eucalyptus  hardwood kraft pulp (EHWK) and northern softwood kraft pulp (NSWK) were used to form the various furnish layers. In certain instances, a debonder was added to the fabric contacting layer and/or a dry strength resin was added to the middle layer. Generally, the first and second outer layers comprised EHWK and each layer comprised 30 percent of the total weight of the web. The middle layer comprised NSWK and generally comprised about 40 percent of the total weight of the web. 
     Each furnish was diluted to approximately 0.2 percent consistency and delivered to a layered headbox and deposited on a Voith Fabrics TissueForm V forming fabric (commercially available from Voith Fabrics, Appleton, Wis.). The wet web was vacuum dewatered to approximately 25 percent consistency and then subjected to rush transfer when transferred to the transfer fabric. The transfer fabric was the fabric described as “Fred” in U.S. Pat. No. 7,611,607 (commercially available from Voith Fabrics, Appleton, Wis.). The rush transfer rate was 28 percent. The web was then transferred to a Tissue Max EX through-air drying fabric (commercially available from Voith Fabrics, Appleton, Wis.). The web was dried with a through-air-dryer resulting in dried tissue web. 
     The dried tissue web was fed to a gravure printing line, similar to that shown in  FIG.  3   , traveling at about 1,000 feet per minute where a latex polymer was printed onto the surface of the sheet. The binder composition was Vinnapas™ EP1133 (commercially available from Wacker Polymers, LP, Allentown, PA). The pH of the latex-based binder was adjusted using NaOH to a pH of approximately 6.0 and allowed to mix for approximately 5 to 30 minutes prior to use in the gravure printing operation. The viscosity of the latex-based binder was in range from 30 to 60 cps when measured at room temperature using a viscometer (Brookfield™ Synchro-lectric viscometer Model RVT, Brookfield Engineering Laboratories Inc. Stoughton, MA) with a #1 spindle operating at 20 rpm. 
     The first side of the dried web was printed with a binding composition using direct rotogravure printing in a pattern as shown in  FIG.  5   . The pattern comprises three elongated hexagons having a length of about 0.02 inch (0.51 mm) and a width of about 0.006 inch (0.15 mm). The print nip distance was varied from 7.0 to 12.0 mm. After printing, the sheet was pressed against and doctored off a rotating drum, which had a surface temperature of approximately 126° C. 
     The print creped tissue web was subjected to further converting to produce a two-ply tissue product by calendering at a pressure of 10 psi and arranging the individual plies in facing relation such that the surface printed with the binder composition formed the two outer surfaces of the two-ply tissue product. The print creped tissue multi-ply web was then cut into individual sheets and folded. The finished product which was subject to physical testing as summarized in Tables 2-4, below.

     Example 2 
     Additional inventive tissue products were produced substantially as described above, with the following changes: A multi-layered basesheet having first and second outer layers comprising EHWK (each layer comprising 33 percent of the total weight of the web) and a middle layer comprising NSWK (comprising 34 percent of the total weight of the web) was manufactured by the UCTAD process described above. The rush transfer rate was 35 percent and the through-air drying fabric was T1205-2 (commercially available from Voith Fabrics, Appleton, Wis. and described in U.S. Pat. No. 8,500,955). The basesheet had a target basis weight of about 30 gsm. 
     The dried tissue web was fed to a gravure printing line, similar to that shown in  FIG.  3   , traveling at about 1,500 feet per minute where a latex polymer was printed onto the surface of the sheet. The binder composition resulted from the cross-linking reaction of a carboxylated vinyl acetate-ethylene terpolymer, an azetidinium-functional cross-linking polymer and a chemically reactive multi-functional aldehyde anti-blocking additive. The carboxylated vinyl acetate-ethylene terpolymer is commercially available from Wacker Polymers, LP (Allentown, PA) under the tradename Vinnapas™ EP-1133. The azetidinium-functional crosslinking polymer is commercially available from Solenis (Wilmington, Del.) under the tradename Kymene 920A. The multi-functional aldehyde anti-blocking additive is commercially available from Kemira (Atlanta, Ga.) under the tradename Fennobond 3000. After printing, the sheet was pressed against and doctored off a rotating drum, which had a surface temperature of approximately 135° C. 
     The print creped tissue web was subjected to further converting to produce a two-ply tissue product by calendering at a pressure of 10 psi and arranging the individual plies in facing relation such that the surface printed with the binder composition were brought into facing arrangement and the outer surface of the two-ply tissue product was substantially free from the binder composition. The print creped tissue multi-ply web was then cut into individual sheets and folded. The finished product which was subject to physical testing as summarized in Tables 5, below.
