## Abstract

Traditional printing and tie-dyeing are an important part of Chinese handicrafts. It consists of three main techniques: batik, tie-dye, and multi-layer dyeing. Among the traditional printing and dyeing techniques, tie-dyeing creates an ever-changing visual artistic effect due to the diversity of its production methods. In modern society with the unprecedented development of technology and information, people’s life rhythm has accelerated, and the opposite “slow fashion” has become popular. More and more people are focusing more on the traditional craft of tie-dyeing. In contemporary fiber art, raw materials have become the soul and foundation of fiber art. This is also the difference between modern fiber art and traditional textile art. Entering the new era, the demand for textiles by people of all countries is also increasing, new functional requirements are put forward for textiles, and functional textiles emerge as the times require. The creative display of nanofibers is a comprehensive grasp of the properties of the fibrous material. It is the creativity and expression generated under the premise of understanding the type, shape, craft, and expression of fiber. It fully reflects the characteristics of the material itself, and it is also the designer’s ideological expression of the texture and shape of the material. It is then materialized into a certain connotation by appropriate technical means. In this paper, manual tie-dyeing is applied to nanofiber materials, making full use of the advantages of modern nanomaterials to promote the development of fabric tie-dyeing technology. In the performance test of the transmittance of nanomaterials to ultraviolet rays, it can be found that the transmittance of nanomaterials through the tie-dyeing process is lower for optical fibers with shorter wavelengths. When the wavelength of ultraviolet light is 313 nm, the transmittance of ZnO to ultraviolet light is 0. When the ultraviolet wavelength is 435 nm, the transmittance of ZnO to ultraviolet light is 45%.

## 1. Introduction

In today’s society, with the rapid development of industry, people also feel the great pressure of urban industrialization. As a result, the world has returned to the theme of art. People are fed up with mechanical indifference. It returns to the pursuit of ancient folk culture, a dilapidated old brick, a pair of ingenious embroidery, a beautiful and beautiful folk song, and a traditional and unique dyeing process. Therefore, the value research of Chinese folk art has become the focus of worldwide attention. Chinese folk art is an aesthetic goal with internationally recognized aesthetic value. The creation of Chinese folk art is also a very deep work, which is worth exploring. Tie-dyeing is a traditional printing and dyeing technique with a long history. Due to its unique technical characteristics and profound cultural heritage, it has been handed down and has been listed as a national intangible cultural heritage. With the development of production equipment and the emergence of new technologies, modern tie-dyeing technology inherits the characteristics of traditional craftsmanship at the same time. It has important research significance for its continuous innovation and development. With the continuous development of science and technology, the use of nanotechnology in the textile industry has just started. Nanotextiles have an incomparable role in rain and water resistance, UV protection, and wear resistance.The use of multiple tie-dyeing processes on the same fabric can make the traditional tie-dyeing process develop from a single color to a multi-color effect. Abraham revisited the tie-dye process in an introductory experiment in organic chemistry with bioinspired and safer substitution of nucleophilic aromatic substitution (SNAr) reactions. Instead of using traditional SNAr substrates, water-soluble reactive dyes do not require any heavy metals, toxic substances, or mordants, but utilize less toxic and safer sodium carbonate to generate cellulose nucleophiles. This reaction produces no waste and the final product - the tie-dyed t-shirt is reusable and biodegradable. Through this experiment, students can see the link between chemistry and environmental health while gaining a practical understanding of dye chemistry using systems thinking approach, but its practicality is not strong [1]. Yang et al. researched and reproduced a Northern Dynasty tie-dyed female silk garment from the China National Silk Museum. In order to achieve the imitation flower effect, the tie-dyeing process parameters were determined. The distance between the two points is 1.4 cm and 1 cm in the longitudinal and transverse directions, respectively. Silk Plain Habutai was chosen as the tie for the two rings. To reproduce the colors of the Northern Dynasty tie-dye garments, it was hand-dyed with gallnut and iron powder to obtain a dark brown color. In a symmetrical and continuous approach, it positions the knotted pattern and adapts it to the garment pattern. The work of this paper has a certain reference value for further research on tie-dyed silk clothing [2]. Textiles with fading effects through ozone oxidation are becoming more and more popular these days. To better understand and apply this process, He et al. utilized an extreme learning machine (ELM) to model the process in terms of pH, temperature, water absorption, time (process), and primary color (textile). He studied the complex factors of ozonation of fading and the factors that affect the color properties of reactive dyed cotton. It was found that RF and SVR outperformed ELM. Because the latter is very unstable in predicting a single output. Both RF and SVR have potential applicability, but SVR is recommended more for practical applications due to its balancer prediction performance and lower time cost training [3]. After hundreds of years of development, Nantong yarn-dyed home cloth has formed exquisite design and unique charm in the structure and pattern. After analyzing the structure and pattern of the homespun series, Wang et al. selected the most classic samples for further study. The results show that there are only several structures of Nantong yarn-dyed soil cloth. However, through the combined use of plain weave, rib weave, and jacquard weave in home textiles, and the variation of different types of twill, it can obtain different textures and rich patterns under limited process conditions, such as zigzag twill, diamond twill, and square weave. Under the coordination of fabric weave and colored yarns, colored yarns are intelligently arranged to form three elements of point, line, and surface, to obtain delicate and colorful patterns [4]. People have always paid more attention to dyeing, but little research has been done on the improvement of composite fibers of fabrics.Nanofiber material refers to a linear material with a certain aspect ratio with a diameter of nanometer scale and a large length. Tenchurin et al. prepared a natural extracellular matrix hyaluronic acid-based nanofiber scaffold with good tissue engineering application prospects by electrospinning technology. Hyaluronic acid is part of many organs and tissues. It is a biologically active ingredient capable of participating in cell proliferation and migration. The high viscosity of the macromolecular biopolymer solution complicates the preparation of nanofibrous scaffolds based on it. Rheological studies have made it possible to determine the composition of the solvent that helps reduce the viscosity of the spinning solution. The maximum Newtonian viscosity of a 1% hyaluronic acid solution in water is 25 Pas. He reduced this parameter to 1.147 Pas using a mixture of ammonia hydrate (10%) and dimethylformamide (2 : 1 ratio). He used a special spinning cell with a small diameter nozzle and high pressure (up to 10 atm) to form hyaluronic acid-based nanofibers with a diameter of 100–300 nm [5]. With the development of technology, higher requirements are put forward for the performance of energy storage devices. Conventional lithium-ion batteries are approaching peak capacity and cannot meet increasing energy density demands. Due to their superior nanostructures, electrospun nanofibrous materials often exhibit some unique properties. Even under the harsh conditions of high sulfur loading and poor electrolyte, it can simultaneously solve the factors restricting the development of lithium-sulfur batteries. Zhang presented the recent progress and structural design of electrospun nanofibers for lithium-sulfur battery cathodes, separators, and interlayers. He analyzed the effect of material properties and structure on the performance of lithium-sulfur batteries. He proposed the research and development direction of electrospun nanofibers for various components of lithium-sulfur batteries [6]. Tenchurin et al. studied nanofibers prepared by solution electrospinning of acrylonitrile, methyl methacrylate, and itaconic acid polymer copolymers as conductive materials. It is suitable for the preparation of biofuel cells (BFC). To increase the electrical conductivity, he continuously exposed it to oxidative thermal stabilization in air and high-temperature vacuum treatment at 1500 and 2300–2550°C. He studied the structure of materials using a variety of techniques, including infrared and Raman spectroscopy. Based on the findings, he determined heat treatment conditions to produce microbial BFC fiber materials with acceptable defect levels and sufficient electrical conductivity [7]. These studies provide a detailed analysis of tie-dyed textiles. It is undeniable that these studies have greatly promoted the development of the corresponding fields. We can learn a lot from methodology and data analysis. However, the research on combining nanofiber materials with the tie-dyeing process is relatively few and not thorough enough and it is necessary to fully apply these techniques to the research in this field.In this paper, the effect of carbonization treatment on the thickness and air permeability of blended fabrics in the tie-dyeing process was carried out in the study of the creativity of nanofiber materials and their application in the expressiveness of the hand-dyeing process. It was found that the thickness of the two fabrics after high-temperature carbonization treatment was reduced, the reduction value was about 0.02–0.03, and the air permeability was also greatly improved. Moreover, the transmittance of nanomaterials to optical fibers with shorter wavelengths is lower. When the wavelength of ultraviolet light is 313 nm, the transmittance of ZnO to ultraviolet light is 0. When studying the advantages of nanofiber materials for antibacterial and deodorizing functions, it was found that with the increase of the concentration of nanopowders, the total number of bacterial colonies was greatly reduced. When the concentration of TiO2 nano-powder was 0.8, the bacterial reduction rate reached 100%, and when the ZnO nanoconcentration was 0.4 g/L, the bacterial reduction rate increased to 82.4%.


## 2. Creativity of Nanofiber Materials and Application Methods in Expressiveness of Hand-Dyeing Technology

### 2.1. Combination of Fiber Technology and Tie-Dyeing Technology

Fiber technology uses various animal and plant fibers as raw materials, such as wool, cotton, hemp, silk, and other natural fibers and man-made fibers, which are processed by weaving, winding, bundling, stitching, and pasting [8, 9]. The emergence of a large number of new materials prompts fiber artists to seek techniques and technologies that are compatible with new materials to express new ideas and achieve artistic innovation [10]. “Creativity” is the technological innovation in the process of promoting the development of materials, and the emergence of new materials has given new thinking to the creators.Tie-dye, also known as twisted valerian, is meant by design intent. It uses needle and thread to tie, sew, embellish, clip, wrap, and other craftsmanship on the fabric, and physically “anti-dye” printing on the fabric is a manual printing and dyeing process. Tie-dyeing is the earliest dyeing method in China. It is said that it has a history of thousands of years since the Qin and Han Dynasties. This is an ancient dyeing method. It is rooted in the hearts of the people with its unique beauty and beautifies people’s lives [11]. The unique tie-dyeing process of tie-dyeing is shown in Figure 1. The beauty of the imprint after dyeing, coupled with the beauty of natural color halo, are the characteristics of tie-dyeing. Therefore, tie-dyeing will become a vigorous vitality with international and historical heritage. Tie-dye, a traditional dyeing wonder, with its simple and natural characteristics, will surely become an artistic treasure of Chinese traditional culture. It shines on the international stage [12].Figure 1
The production process of traditional tie-dyeing process.Modern tie-dyeing is a modern tie-dyeing process gradually developed by traditional tie-dyeing technology under the support of modern technology. Modern tie-dyeing techniques and traditional tie-dyeing techniques mostly use a variety of tie-dyeing methods. After dyeing, the patterns and patterns formed are different, as shown in Figure2 [13]. The unique spinning and dyeing technology of “National Essence Three Dyeing” is combined with modern dyeing and finishing technology. Not only are there rich patterns in the pattern, but compared with the traditional simple colors and technical methods, the colors can also be expressed in accordance with the design intentions. It presents brilliant and colorful colors. At the same time, modern tie-dyeing technology can also make the fabric have better shape memory and shape by physically treating the folds of the fabric, such as high temperature and high pressure. It thus creates a three-dimensional visual “new look”. This is very different from ordinary fabrics or ready-to-wear [14]. The surface texture of modern tie-dye refers to the texture of the surface of the fabric. It mainly includes the plane texture observed with the naked eye and the three-dimensional texture felt through the touch. The traditional tie-dyeing technique is relatively simple, and the pure expression of color and texture is rare. Tie-dye works can be made by comprehensively using various “tie” and “dye” techniques, which can enrich the performance of the picture.Figure 2
Comparison of modern tie-dye and traditional tie-dye.


### 2.2. Characteristics and Applications of Tie-Dye Art

The expression and dyeing rules of Chinese tie-dye art are not based on the representation of objective reality. Different from Western painting methods, it only emphasizes the portrayal of objective things. On the other hand, Chinese folk art emphasizes subjective intuition, attaches great importance to the thinking and emotions of the soul, and pursues beautiful ideals and wishes [15]. It can be seen that the source of Chinese tie-dye art creation lies in its subjective aesthetic consciousness, but in its inner emotions. In this process, Chinese tie-dye has produced its complete artistic expression. It forms an expressive art characterized by subjective image modeling, color, and multi-angle perspective [16].Through the investigation of the coloring technology and artistic expression of dyeing and finishing art, this paper further clarifies the characteristics of tie-dyeing. Although in today’s society, the art forms of tie-dye are various, they cannot get rid of their most fundamental art form and fundamental dyeing. Traditional tie-dye art has unique art forms and unique dyeing techniques. It brings more creativity to designers and craftsmen. They are free to create according to their own experience and spirituality. Through their creative creations, tie-dye art transcends the limitations of time and space [17]. In a limited space, tie-dye is not only limited to clothing, it has more applications.In addition, there are dozens of ways to tie flowers at present. It can be handcrafted, knitted, hooked, embroidered, inlaid, and other craftsmanship. It allows the product to truly show the multiple aesthetics of modern and classical, simple and luxurious, transparent and hazy. In recent years, in interior decoration, the effect of tie-dye is natural and simple, fresh and elegant, and unique [18]. The designer uses his own understanding and love of life and uses the artistic expression and dyeing technology of tie-dye to perfectly reflect contemporary tie-dye.Pattern craftsmanship can be divided into abstract and figurative, while the color craftsmanship of tie-dye art includes color blooming and traditional blue and white. Through the study of tie-dye’s unique pattern and color technology, it uses unique expression and symbolic language to stimulate thinking and innovation in contemporary design art. It provides rich design elements and expressions for the creation of contemporary design art [19].Tie-dye abstract patterns are based on specific craftsmanship. There are three kinds of abstract forms made by complicated hand-tie: abstract random points, changeable lines, and random smudges [20]. In a nutshell, the characteristics of the abstract pattern are indeterminate and random, and it adopts the method of interspersed dyeing. In abstract patterns, on the one hand, irregular blooming effects can appear. On the other hand, it can also form a regular artistic form according to the method of manual tie-dyeing, and the morphological characteristics of abstract tie-dye are various.The tie-dye color process of abstract patterns is mainly painted. According to the analysis, due to the combination of the painting process and the abstract process, the smudge and color smudge changes are very beautiful. But in abstract crafts, the richness and visual effect of monochromatic blooming are obviously worse [21].The figurative pattern of tie-dye is a line-centered tie-dye fabric, which mainly adopts three structures of point, line, and surface. Among them, there are four main types of dots: round dots, square dots, simple figurative, and abstract freehand dots. In the tie-dye process, dots are the most commonly used form and the one that best reflects its characteristics [22]. Among them, the common tie-dyeing techniques are fish roe, spider flower, drunken eye, beancurd cloth, and ancient money patterns. Square-dot tie-dyeing is mainly done by bandaging or sewing on the part of the fabric. The specific and realistic points mainly rely on suture technology to sew the outer edges of the shapes, such as heart-shaped, small plum blossoms, leaves. The pointed shape of abstract freehand is relatively simple, and it is mainly shaped by bundling and tying. It has the characteristics of freedom and flexibility [23].Tie-dyeing has been around for many years in China. However, due to the influence of region, culture, technology, concept, etc., it remains in the workshop-style production of folk handicrafts. Products are also limited to some simple cotton and linen materials. Some tourist products or souvenirs are made by it. No matter whether the variety, color, pattern, or style is very monotonous, its scope of application is very limited. This is very unfavorable for the inheritance and protection of the traditional cultural heritage of tie-dye [24]. Nanomaterials are widely used not only on chemical fibers but also on chemical fibers—natural fibers and natural fibers. Nanomaterials with anti-ultraviolet and antibacterial functions have been developed and applied to natural fibers such as cotton, hemp, and wool by adding them. It can introduce modern burnt-out technology into the tie-dyeing process and use nanofiber materials. It organically combines the two processes of burnt-out and tie-dye through physical and chemical methods. By developing a new process of burnt-out tie-dyeing, the fabrics produced have both burnt-out characteristics and tie-dye style. It has more artistic and practical value, and it opens up a new way for the inheritance and utilization of tie-dye craftsmanship.Among inorganic acids, sulfuric acid is strongly acidic and reacts strongly with cellulose. Under certain conditions, cellulose fibers can also be dehydrated and carbonized, and sulfuric acid is a non-volatile strong acid with a low price. It is the acid of choice for burnt-out tie-dyeing.Table1 shows the effect of different sulfuric acid concentrations on the burnt-out effect. When the volume concentration of sulfuric acid solution reaches 55 mL/L, the burnt-out effect is obvious, which is the best process parameter.Table 1

98% concentrated sulfuric acid (mL/L)Rotten flower effect98% concentrated sulfuric acid (mL/L)Ragged flower effect5Not obvious35Slightly obvious15Not obvious45More obvious25Not obvious55ObviousThe success or failure of carbonization has a great influence on the success or failure of burnt-out. If the carbonization is not complete, the fiber will be eroded, the silk is opaque, the pattern is unclear, the baking is too much, and the carbonized fiber residue is black and brown, which is difficult to remove from the fiber. Due to the non-uniform physical structure of cellulose fibers, the initial hydrolysis occurs at the edge of the amorphous region and the entire row, resulting in a faster rate of hydrolysis. In the whole composition, the hydrolysis reaction is significantly reduced. Usually, at 20∼100°C, the acid concentration remains unchanged, and at 10°C, the hydrolysis rate of fiber can be increased by 2∼3 times. The sulfuric acid immersed on the surface of the fiber will become concentrated sulfuric acid after being concentrated at a high temperature. The concentrated sulfuric acid can absorb the hydrogen and oxygen in the cellulose and carbonize the fiber. It can be seen in Table2.Table 2

### 2.3. Preparation Process of Nanofibers

Nanomaterials are a new type of ultra-fine solid materials with small particle sizes and are often referred to as nanoparticles. Electrospinning technology is by far one of the easiest and most efficient methods to produce nanofibers. In the electrospinning process, the high-speed jet stage is the second important stage. The research on the fluid and charge in the high-speed jet stage is very complicated, and the modeling analysis is generally carried out under the assumption of ideal conditions. The most typical of them are leakage current dielectric model analysis and slender body model analysis.The Leaky Dielectric Model is one of the typical models applied in the high-speed jet stage of electrospinning. The model mainly makes the following assumptions for the high-speed jet: First, there is no charge inside the high-speed jet, only the outside of the jet is charged, and any charge inside the jet will be quickly transferred to the surface of the jet. Second, the jet fluid is a good insulator, and there is a continuous tangential electric field force on the jet surface. The model is applied in the high-speed jet stage of electrospinning, and the core part is the characteristic delay time representation of the charge and the jet dynamics time representation. The characteristic delay time of the charge is expressed as(1)t1∼αε1c.In the above formula the variables,c, ε and α are the conductivity of the solution, the permittivity of vacuum, and the permittivity ratio of vacuum, respectively.The jet dynamics time is expressed as:(2)t2∼Lv∼LrjQ.In the above formula,rj represents the radius of the jet when it is about to break, Q represents the flow velocity of the jet, v represents the typical value of the axial velocity of the jet, and L represents the length of the high-speed fine jet. From this formula, it can be known that the controllable process parameter flow rate Q will be an important parameter affecting the steady state of the jet. It will have an impact on the key performance indicators of electrospun nanofiber preparation.The slender body model is widely used in approximating the stretching and breaking of droplets and jets. Also, in the high-speed jet of electrospinning, the most widely used model is the slender body model. The assumptions of the slender body model are as follows: the axial velocity of the jet on the same section is the same, and the radius of the jet changes slowly with the axial direction.The current in the jet is generally divided into two parts, as shown in the following formula (3), I1 represents the surface current, and I2 represents the ohmic current.(3)I=I1+I2.Figure3 is a model schematic diagram of the ohmic conduction resistance and surface resistance of the jet. It can be seen that the ohmic conduction resistance is inversely proportional to the cross-sectional area of the jet and proportional to the length of the jet. For the surface resistance model of the jet, since the positive charge is only distributed on the surface of the jet, the surface area of the jet is proportional to the radius of the jet. So the surface resistance of the jet is proportional to the radius of the jet. Ohmic resistance and jet resistance Rs are expressed as the following two formulas:(4)R∼1A∼r−2Rs∼1A−1/2∼r−1.Figure 3
Jet ohmic resistance and jet surface resistance.
(a)(b)Since the current is inversely proportional to the resistance, the ohmic current Ic and the surface current I s are expressed as follows:(5)I2∼R−1∼A∼r2I1∼Rs−1∼A1/2∼r.It can be got(6)I=πr2aE+2πrσμIn the above formula,σ represents the density of electric charges, E represents the strength of the electric field, and a represents the conductivity of the fluid. μ is the flow velocity, due to the flow(7)Q=μπr2.So(8)I=πr2aE+2πrσQπr2.During the electrospinning process, the high-speed charged jet is highly stretched by a strong electric field, and the solvent is continuously volatilized, so the jet is generally very fine.The axial instability is caused by the tangential electrostatic force on the surface charge of the high-speed jet. Under the combined action of the viscous force and this tangential force, the high-speed jet deforms and flows. It uses the method of establishing an orthogonal coordinate system to analyze the jet axisymmetric model, as shown in Figure4.Figure 4
Establishment of orthogonal coordinate system of axisymmetric model.As shown in Figure4, in the X/Y/Z orthogonal coordinate system, the direction of the undisturbed fluid is Z. The jet center is deformed in the XY plane, ignoring the distortion of its centerline. Let d^ be the tangent vector to the centerline of the jet, and ε^ to be the normal vector to the undisturbed fluid. Because the jet centerline will be distorted, resulting in a pole-double density P. The direction of the Pf point is ε, and the change of the P(s) point is related to the jet length. The electric field formula with pole dipole density is:(9)∫df′pf′x−xf′x−xf′≈xPz∫dz′1z′−z+r23/2≈xpfr2.Under this case(10)f≈ε≈^x^.If the local radius curvature of the jet isR, the above formula can be modified as:(11)G=εε^+yy^−xf′x−xf′=G≈s′21−εR+ε2+y21/2.Then(12)∫df′ωf′x−xf′≈2ωflnrL+εωfRlnLr+εpfr2.In the formula,L represents the characteristic length of the shaft, so the disturbance amount u caused by instability can be finally obtained as:(13)u¯ε,y,f=φ∞+2ωxlnLr+εωxRlnLr+εpfr2.ε is the coordinate of the cardinal direction, and f is the length of the arc.

If the carbonization is not complete, the fiber will be eroded, the silk is opaque, the pattern is unclear, the baking is too much, and the carbonized fiber residue is black and brown, which is difficult to remove from the fiber. Due to the non-uniform physical structure of cellulose fibers, the initial hydrolysis occurs at the edge of the amorphous region and the entire row, resulting in a faster rate of hydrolysis. In the whole composition, the hydrolysis reaction is significantly reduced. Usually, at 20∼100°C, the acid concentration remains unchanged, and at 10°C, the hydrolysis rate of fiber can be increased by 2∼3 times. The sulfuric acid immersed on the surface of the fiber will become concentrated sulfuric acid after being concentrated at a high temperature. The concentrated sulfuric acid can absorb the hydrogen and oxygen in the cellulose and carbonize the fiber. It can be seen in Table2.Table 2

## 2.3. Preparation Process of Nanofibers

Nanomaterials are a new type of ultra-fine solid materials with small particle sizes and are often referred to as nanoparticles. Electrospinning technology is by far one of the easiest and most efficient methods to produce nanofibers. In the electrospinning process, the high-speed jet stage is the second important stage. The research on the fluid and charge in the high-speed jet stage is very complicated, and the modeling analysis is generally carried out under the assumption of ideal conditions. The most typical of them are leakage current dielectric model analysis and slender body model analysis.The Leaky Dielectric Model is one of the typical models applied in the high-speed jet stage of electrospinning. The model mainly makes the following assumptions for the high-speed jet: First, there is no charge inside the high-speed jet, only the outside of the jet is charged, and any charge inside the jet will be quickly transferred to the surface of the jet. Second, the jet fluid is a good insulator, and there is a continuous tangential electric field force on the jet surface. The model is applied in the high-speed jet stage of electrospinning, and the core part is the characteristic delay time representation of the charge and the jet dynamics time representation. The characteristic delay time of the charge is expressed as(1)t1∼αε1c.In the above formula the variables,c, ε and α are the conductivity of the solution, the permittivity of vacuum, and the permittivity ratio of vacuum, respectively.The jet dynamics time is expressed as:(2)t2∼Lv∼LrjQ.In the above formula,rj represents the radius of the jet when it is about to break, Q represents the flow velocity of the jet, v represents the typical value of the axial velocity of the jet, and L represents the length of the high-speed fine jet. From this formula, it can be known that the controllable process parameter flow rate Q will be an important parameter affecting the steady state of the jet. It will have an impact on the key performance indicators of electrospun nanofiber preparation.The slender body model is widely used in approximating the stretching and breaking of droplets and jets. Also, in the high-speed jet of electrospinning, the most widely used model is the slender body model. The assumptions of the slender body model are as follows: the axial velocity of the jet on the same section is the same, and the radius of the jet changes slowly with the axial direction.The current in the jet is generally divided into two parts, as shown in the following formula (3), I1 represents the surface current, and I2 represents the ohmic current.(3)I=I1+I2.Figure3 is a model schematic diagram of the ohmic conduction resistance and surface resistance of the jet. It can be seen that the ohmic conduction resistance is inversely proportional to the cross-sectional area of the jet and proportional to the length of the jet. For the surface resistance model of the jet, since the positive charge is only distributed on the surface of the jet, the surface area of the jet is proportional to the radius of the jet. So the surface resistance of the jet is proportional to the radius of the jet. Ohmic resistance and jet resistance Rs are expressed as the following two formulas:(4)R∼1A∼r−2Rs∼1A−1/2∼r−1.Figure 3
Jet ohmic resistance and jet surface resistance.
(a)(b)Since the current is inversely proportional to the resistance, the ohmic current Ic and the surface current I s are expressed as follows:(5)I2∼R−1∼A∼r2I1∼Rs−1∼A1/2∼r.It can be got(6)I=πr2aE+2πrσμIn the above formula,σ represents the density of electric charges, E represents the strength of the electric field, and a represents the conductivity of the fluid. μ is the flow velocity, due to the flow(7)Q=μπr2.So(8)I=πr2aE+2πrσQπr2.During the electrospinning process, the high-speed charged jet is highly stretched by a strong electric field, and the solvent is continuously volatilized, so the jet is generally very fine.The axial instability is caused by the tangential electrostatic force on the surface charge of the high-speed jet. Under the combined action of the viscous force and this tangential force, the high-speed jet deforms and flows. It uses the method of establishing an orthogonal coordinate system to analyze the jet axisymmetric model, as shown in Figure4.Figure 4
Establishment of orthogonal coordinate system of axisymmetric model.As shown in Figure4, in the X/Y/Z orthogonal coordinate system, the direction of the undisturbed fluid is Z. The jet center is deformed in the XY plane, ignoring the distortion of its centerline. Let d^ be the tangent vector to the centerline of the jet, and ε^ to be the normal vector to the undisturbed fluid. Because the jet centerline will be distorted, resulting in a pole-double density P. The direction of the Pf point is ε, and the change of the P(s) point is related to the jet length. The electric field formula with pole dipole density is:(9)∫df′pf′x−xf′x−xf′≈xPz∫dz′1z′−z+r23/2≈xpfr2.Under this case(10)f≈ε≈^x^.If the local radius curvature of the jet isR, the above formula can be modified as:(11)G=εε^+yy^−xf′x−xf′=G≈s′21−εR+ε2+y21/2.Then(12)∫df′ωf′x−xf′≈2ωflnrL+εωfRlnLr+εpfr2.In the formula,L represents the characteristic length of the shaft, so the disturbance amount u caused by instability can be finally obtained as:(13)u¯ε,y,f=φ∞+2ωxlnLr+εωxRlnLr+εpfr2.ε is the coordinate of the cardinal direction, and f is the length of the arc.


## 3. Experiment Preparation for Hand Tie-Dyeing Process

### 3.1. Basic Process Flow

There are various tie-dye art techniques, the fabric surface has a very rich mechanism effect and unique color halo effect, and its technical and artistic expression is extremely free. The burnt-out/tie-dye process combines the advantages of the two, and the products produced can continue to undergo post-processing such as tie-dye, batik, and embroidery to increase the added value of the product. The process flow is shown in Figure5:Figure 5
Process flow.The process route fully considers the style characteristics of the product, and the ideal process is optimized and screened after many trials. The process is short, the process is simple, manpower, material, and financial resources are saved, and the dyeing effect is good.The indexes of the dyes in the dyeing process are shown in Table3. Before dyeing, the dye and salt should be dissolved in warm water. The fabric is first soaked in water and then squeezed to semi-dry. After dyeing, rinse the fabric with water until the water is clear, remove the floating color, remove knots, and then soap. The heating curve of the tie-dyeing process is shown in Figure 6.Table 3

### 3.2. Evaluation of Fabric Style

Fabric style refers to a comprehensive evaluation of fabric, both visually and tactilely. It reflects some of the outer properties and inner qualities of the fabric. For example, the polyester-cotton fabrics used are light in texture, soft and smooth to the touch, wrinkle-resistant, and iron-free, and durable. The pure cotton plain fabrics used in traditional tie-dyeing have different style characteristics according to different specifications. The initial plain cloth is rough in appearance and texture, but durable. The fine cloth is light and thin, smooth and clean, soft to the touch, and smooth and clean with very few impurities. It has the natural luster of cotton fibers. There are two types of evaluation methods for fabric style: subjective evaluation and objective evaluation. Subjective evaluation refers to the feel when the fabric is touched by hand or skin, while objective evaluation refers to measuring the physical properties of the relevant fabric with an instrument. This paper uses YG (B)141D digital fabric thickness gauge and fabric air permeability meter to measure the thickness and air permeability of fabrics before and after treatment.

## 4. Data of the Creativity of Nanofiber Materials in the Manual Tie-Dyeing Process

### 4.1. Effect of Carbonization on Properties of Blended Fabrics

Fabric thickness refers to the distance from the upper surface to the lower surface of the fabric. Thickness is very important for the calculation of the number of fabric layers of the cutting machine and the adjustment of sewing machine parameters in garment production. The thickness of the fabric has a great influence on the wearing performance of the fabric, such as the fabric’s fastness, warmth, breathability, wind resistance, rigidity and flexibility, and drapability. It is largely related to fabric thickness.It measures the thickness of the fabric with a thickness gauge. The experimental fabric thickness gauge had a presser foot area of 50 mm2, a pressure of 100 cN/cm2, and a pressing time of 10 seconds. Clothing is not only decorative but also maintains the energy exchange between the body and the environment. Clothes are the final product of textiles, and to understand this property of fabrics, breathability must be measured. This is directly related to the performance of the fabric. The main reasons that affect its air permeability are the number and size of voids and voids between warp, weft, and fibers, fiber crimp, yarn thickness and twist, fabric thickness, fabric density, finishing, etc. The effect of carbonization on the thickness and air permeability of the blended fabric is shown in Figure7.Figure 7
Effect of carbonization on the thickness and air permeability of blended fabrics.It can be seen from Figure7 that after the blended fabric is carbonized by sulfuric acid at a high temperature, the thickness of both fabrics is reduced, and the reduction value is about 0.02–0.03. The reason is that the sulfuric acid in the blended fabric is concentrated into concentrated sulfuric acid at high temperature, which makes the cotton in the fabric hydrolyzed into small molecules and easily soluble in water. At the same time, concentrated sulfuric acid will also carbonize the cotton cellulose molecules in the ratio of two hydrogens and one oxygen, and after fully washing, the cotton component in the blended fabric is washed away. It leaves only nanofibers, which reduces the thickness of the fabric. The air permeability of 1 T/C fabric increased from 635 L/m2s to 1635 L/m2s after carbonization. After carbonization, the air permeability of 2 T/C fabric increased from 420 L/m2s to 936.1 L/m2s, and the air permeability of blended fabrics was obviously improved after sulfuric acid high-temperature carbonization. After carbonization, the cotton fibers are carbonized and removed after washing, which increases the gap between the warp and weft yarns and the fibers, increasing the air permeability. At the same time, under high-temperature conditions, sulfuric acid can carbonize cotton fibers.


### 4.2. Application of Nanomaterials in Functional Textiles

Many nanofiber materials can play a role in UV shielding and protection, such as ZnO, MgO, TiO2, SiO2, CaCO3, talc, China clay. Their transmission is shown in Figure 8.Figure 8
UV transmittance properties of several nanomaterials.It can be seen from Figure8 that the transmittance of these nanomaterials to optical fibers with shorter wavelengths is lower. At the ultraviolet wavelength of 313 nm, the transmittance of ZnO to ultraviolet light is 0, and at the ultraviolet wavelength of 435 nm, the transmittance of ZnO to ultraviolet light reaches 45%. The above substances are made into ultra-fine powder so that the particle size is close to or smaller than the wavelength of the light wave, so that the light absorption or reflection is significantly increased. In addition, the surface energy of the nanomaterial is increased due to its volume effect (small scale effect). It is easier to bond when blended with polymers. The composite functional fiber has uniform nanoparticles and has good stability and durability.Nanotechnology is a micromolecular technology. It uses zinc, bromine, and other ingredients in natural fibers, and then goes through nano-processing and then textile processing, to achieve various antibacterial and deodorant effects. In textile production, it forms new nanoparticles by analyzing fibers of different raw materials. Among them, micromolecules such as zinc and bromine can greatly improve the antibacterial ability of fabrics, and they can also adsorb harmful microorganisms on fabrics through nanoparticles. It achieves the effect of antibacterial and deodorization, which brings unprecedented convenience to people. Figures9 and 10 are the evaluation of the antibacterial efficiency of TiO2 and ZnO, respectively.Figure 9

Evaluation of ZnO antibacterial efficiency.It can be seen from Figure9 that with the increase of the concentration of nano-powder, the total number of bacterial colonies is greatly reduced, and at the concentration of 0.8 g/L TiO2 nano-powder, the bacterial reduction rate reaches 100%.It can be seen from Figure10 that the bacterial reduction rate increased by 49.1% when the ZnO nanoconcentration increased from 0.2 g/L to 0.4 g/L.

## 5. Conclusion

With the continuous development of society, hand tie-dyeing technology is becoming more and more mature. The use of hand tie-dyeing in clothing and clothing all reflects people’s admiration for the beauty of nature and their longing for a better life, as well as people’s wisdom. This paper investigates the creativity of nanofiber materials and their application in the expressive power of the hand tie-dyeing process. Due to the structural characteristics of nanofibers themselves, many properties of textiles are improved. However, traditional tie-dyeing is only available in some ethnic minority areas and tourist areas. Although it is very distinctive, it cannot keep up with the fashion trend of modern fashion. At present, the development, application, and development direction of nanomaterials mainly include a variety of fiber additions, a variety of powder composites, and a variety of functional composites. It adopts the blending spinning method, addition method during polymerization, post-finishing method, and other methods, and applies it to the fields of new functional textiles such as anti-ultraviolet, antibacterial, and deodorization. It has laid a solid foundation for its application in the textile field. Nanotechnology is one of the three pillar industries of information, energy, and new materials in the twenty-first century. Its application will provide a new economic growth point for the development of China’s textile, printing and dyeing industries. With the innovation of production equipment and technology, the selection of raw materials for modern tie-dyeing is no longer limited to natural dyes and fabrics. Modern tie-dye has more artistic expression and vitality, and it is more in line with the diversified needs of modern society.
