Description

TECHNICAL FIELD

[0001] The present application relates to the field of textile processing, more particularly, it relates to a quick-drying fabric and a preparation method thereof. BACKGROUND

[0002] The quick-drying fabric is a chemical fiber fabric with high efficient moisture absorption and sweat releasing function. The sweat conduction and evaporation are accelerated through the optimization of special-shaped fiber structure and hydrophilic agent treatment, and the quick-drying fabric is widely used in the field of sportswear. The quick-drying fabric contains indexes such as moisture absorption, sweat releasing and quick-drying, and can be used to prepare down jackets, sun protection clothes and outdoor jackets.

[0003] The quick-drying fabric is generally close to the skin and easy to cause friction. For example, the sun protection clothes are directly in contact with the skin, and long-term wearing may cause dermatitis, allergy and other problems. In addition, although the quick-drying fabric can quickly release sweat, the air permeability is low. At the same time, the quick-drying fabric prepared by polyester fiber has poor flexibility, which affects the wearing comfort, and also has the problem of static electricity.

[0004] Therefore, how to prepare a new quick-drying fabric with the advantages of soft fabric, good air permeability, good flexibility and good antistatic property is a problem to be solved. SUMMARY

[0005] In order to prepare a new quick-drying fabric with the advantages of soft fabric, good air permeability, good flexibility and good antistatic property, the present application provides a quick-drying fabric and a preparation method thereof.

[0006] In the first aspect, the present application provides a quick-drying fabric, which adopts the following technical scheme: A quick-drying fabric is prepared by weaving warp yarn and weft yarn after antistatic treatment. The warp yarn is prepared by blending polyester fiber and lyocell fiber, and the weft yarn is prepared by blending polyester fiber and cotton fiber. The polyester fiber contains the following raw materials by weight: polyester chip 90-120 parts, toughening fiber 2-5 parts, porous filler 2-8 parts, compatibility agent 4-10 parts, dispersing agent 1-2 parts and lubricant 1-2 parts.

[0007] By adopting the technical scheme, the polyester fibers and lyocell fibers are prepared into warp yarns, and the polyester fibers and cotton fibers are prepared into weft yarns, the lyocell fibers are endowed with natural cellulose structure to give the fabric a silky smooth touch, the surface smoothness of the fabric can reduce the friction coefficient with the skin, balance the friction of the polyester fibers on the skin, improve the skin-friendly softness of the quick-drying fabric, and cooperate with the soft touch of the cotton fibers to further improve the softness of the fabric; the nano-scale pores of the lyocell fibers can quickly absorb sweat, cooperate with the moisture absorption and flow guiding effect of the cotton fibers on sweat, and the groove structure of the polyester fibers can conduct water to the outer layer of the fabric through capillary effect, and after the two are blended, a two-way moisture guiding network is formed to improve the soft touch and air permeability and quick-drying property of the finished product; and after the anti-static treatment, the anti-static effect of the finished product can be improved.

[0008] The polyester chips are compounded with toughening fibers, porous fillers and other substances, the toughening fibers are connected and toughened to improve the flexibility of the polyester fibers, the porous fillers are porous and breathable, the compatibility agent is used to improve the compatibility and connection effect of the toughening fibers, the porous fillers and the polyester chips, the dispersing agent is used to make the toughening fibers and the porous fillers uniformly dispersed and contacted with the polyester chips, so as to uniformly improve the flexibility and air permeability of the polyester fibers, and the lubricant is used to facilitate the extrusion molding of the polyester fibers and ensure the quality of the polyester fibers, so that the prepared quick-drying fabric has good flexibility and good air permeability.

[0009] Preferably, the toughening fibers are composed of modified carbon fibers, modified silicon oxide fibers and cellulose nanofibers in a mass ratio of 1:0.5-0.8:0.1-0.2.

[0010] By adopting the technical scheme, the modified carbon fibers, the modified silicon oxide fibers and the cellulose nanofibers are cooperated, the three-dimensional network structure of the carbon fibers disperses stress, and the high flexibility of the carbon fibers can inhibit excessive deformation of the polyester molecular chain, and the nano-scale size effect can reduce local stress concentration to improve the flexibility of the polyester fibers; the hydrogen bond network is formed between the surface hydroxyl groups of the silicon oxide fibers and the polyester matrix to enhance the interfacial bonding force, and the small size effect induces micro-cracks to consume energy and improve the elongation at break; and the flexibility of the cellulose nanofibers further improves the flexibility of the finished polyester fibers, the hydrogen bond network is formed between the surface hydroxyl groups of the cellulose nanofibers and the polyester molecular chain to further enhance the interfacial bonding force, thereby further improving the flexibility of the polyester fibers.

[0011] The porous fillers and the cellulose nanofibers are cooperated, the porous effect of the porous fillers is combined with the porous effect of the cellulose nanofibers to further supply gas diffusion and improve the air permeability. Preferably, the modified carbon fibers are prepared from carbon fiber filaments and polybutylene succinate in a mass ratio of 1:0.24-0.32.

[0012] By adopting the technical scheme, the carbon fiber filaments are bonded with polybutylene succinate on the surface, a flexible chain segment of the polybutylene succinate is used to form a physical winding on the surface of the carbon fiber, a flexible interface layer is formed between the carbon fiber and the polyester matrix, impact energy is absorbed through stress transmission and micro-crack passivation, thereby improving the flexibility of the modified carbon fiber in the polyester fiber, and the polybutylene succinate can be compatibly connected with the polyester chip, further improving the bonding effect and bonding stability of the modified carbon fiber in the polyester fiber; meanwhile, the carbon fiber provides rigid support, the elastic deformation of the polybutylene succinate can inhibit brittle fracture, and the mechanical properties of the fiber are ensured during fiber stretching, so that the quality of the finished product of the quick-drying fabric is not easily affected even after multiple washes, and the service life of the quick-drying fabric is prolonged.

[0013] Preferably, the modified silica fiber is prepared from silica fiber and organic silicon modified acrylic resin with a mass ratio of 1:0.22-0.3.

[0014] By adopting the technical scheme, the organic silicon modified acrylic resin forms a flexible chain segment on the surface of the silica fiber, improves the flexibility of the polyester fiber; and the bond energy of the siloxane bond is higher than that of the C-C bond, which can effectively disperse stress, the interfacial bonding force between the modified silica fiber and the polyester matrix is enhanced, and the strength of the finished fabric is improved.

[0015] The silica fiber has a certain porosity, and the ratio of the silica fiber and the organic silicon modified acrylic resin is limited, so that the pores in the silica fiber are not completely blocked by the organic silicon modified acrylic resin, the porous structure forms a micron or nanometer pore network in the fiber, the pore structure of the silica fiber is not completely destroyed in the spinning process, part of the pore channels penetrate the fiber cross section, allowing air molecules to pass through, and cooperating with the large specific surface area, not only can form local micropores between the polyester matrix to enhance the air permeability, but also can better bond with the polyester matrix, ensuring the mechanical properties of the polyester fiber while increasing the air permeability.

[0016] The organic silicon modified acrylic resin increases the water contact angle by reducing the surface energy of the fiber, reduces water adsorption, and cooperates with the water guide network formed by the silica fiber and the modified carbon fiber to further improve the quick-drying effect of the fabric.

[0017] Preferably, the porous filler is composed of hydrophobic silica gel particles and molecular sieve composite material with a mass ratio of 1:0.2-0.5.

[0018] By adopting the above technical solution, the combination of hydrophobic silica particles and molecular sieve composite material improves the air permeability of polyester fibers by utilizing the porous effect of silica particles and molecular sieves. Combined with the hydrophobic effect of silica particles, the quick-drying properties of the fabric are guaranteed. Combined with the filling effect of the hydrophobic silica particles and molecular sieve composite material, the toughness of silica particles and the bonding effect between the grafted molecular sieve and the polyester matrix are utilized to further improve the flexibility and strength of the finished quick-drying fabric. Even after repeated friction and washing, the quality of the quick-drying fabric is not easily affected, thus extending the service life of the quick-drying fabric.

[0019] Preferably, the molecular sieve composite material is prepared from molecular sieve, polycaprolactone microparticles and polyvinyl alcohol solution in a mass ratio of 1:0.2-0.28:0.22-0.3.

[0020] By adopting the above technical solution, polycaprolactone microparticles are loaded onto the surface of the molecular sieve and bonded to a polyvinyl alcohol solution. When preparing the molecular sieve composite material, the supporting effect of the polycaprolactone microparticles creates a network of pores between the molecular sieve and the polyvinyl alcohol film. During the melt spinning process of polyester chips, the temperature exceeds the boiling point of polycaprolactone by about 250°C, causing the polycaprolactone to gradually decompose. The original positions occupied by the microspheres can not only accommodate the polyester matrix, but also improve the bonding effect between the molecular sieve composite material and the polyester matrix by combining the bonding effect between the polyester matrix and the polyvinyl alcohol. Furthermore, the gradually decomposed gas, combined with the bonding effect between the polycaprolactone and the polyester matrix, can also regulate and balance the air permeability of the polyester fiber and the interfacial bonding effect between the molecular sieve composite material and the polyester matrix. Moreover, after the polyvinyl alcohol solution is formed into a film, water vapor can pass through, which improves the air permeability compared to pure polyester fiber fabrics.

[0021] Preferably, the compatibilizer is composed of maleic anhydride-grafted POE, polyvinyl butyral, and silane coupling agent KH-570 in a mass ratio of 1:0.5-0.7:0.3-0.5.

[0022] By employing the above technical solution, maleic anhydride-grafted POE, toughening fibers, and silane coupling agent KH-570 are combined. The polarity of the maleic anhydride in the grafted POE is compatible with the ester groups in the polyester chips. The non-polar POE segments can physically entangle with modified carbon fibers, modified silica fibers, and other materials, forming a bridge connection structure. This improves the compatibility between the toughening fibers and the polyester matrix. The addition of silane coupling agent KH-570 further enhances the crosslinking effect between the modified carbon fibers and modified silica fibers and the polyester matrix. Combined with the high toughness of the maleic anhydride-grafted POE, the bridge structure, combined with high toughness, buffers the internal stress between the modified carbon fibers and modified silica and the polyester matrix, thereby further balancing the flexibility and strength of the polyester fibers and extending the service life of the quick-drying fabric.

[0023] Polyvinyl butyral (PVB), silane coupling agent KH-570, and porous fillers are combined. The hydroxyl groups in PVB connect with the PVB on the surface of the molecular sieve composite material, and the butyraldehyde groups in PVB connect with the ester groups in the polyester matrix, reducing interfacial tension. The silane coupling agent improves the compatibility between the silica gel particles and the polyester matrix, resulting in a better connection between the porous filler and the polyester matrix. The flexible branches in PVB not only increase the flexibility of the polyester fibers but also inhibit polyester crystallization, improve the dispersion uniformity of the porous filler, and ensure that the finished quick-drying fabric has good flexibility while maintaining a certain degree of breathability.

[0024] Preferably, the lubricant is composed of ethoxylated stearamide and erucamide in a mass ratio of 1:0.5-1.

[0025] By adopting the above technical solution, ethoxylated stearamide provides initial lubrication, and erucamide maintains long-term smoothness, ensuring the preparation effect of polyester fiber; in addition, ethoxylated stearamide can also impart antistatic properties to the fiber, thereby ensuring that the polyester fiber maintains its mechanical properties while being formed.

[0026] Preferably, the antistatic treatment uses an antistatic composite liquid, which is composed of an antistatic agent SN solution, a chitosan quaternary ammonium salt solution, and nano silver powder in a mass ratio of 1:0.4-0.7:0.1-0.3.

[0027] By adopting the above technical solution, the antistatic agent SN solution is adsorbed onto the fiber surface through quaternary ammonium salt cations. The hydrophilic groups absorb moisture to form a conductive layer, neutralizing the static charge. The ethylene oxide segments in its molecular structure enhance compatibility with polyester, improving the antistatic effect of polyester fibers. Combined with the viscosity of the chitosan quaternary ammonium salt solution, it is easy to adhere to the surface of polyester fibers. The positively charged quaternary ammonium groups combine with the fibers, destroying bacterial cell membranes to achieve antibacterial effect. At the same time, it reduces surface resistance through hygroscopicity and also has good film-forming properties, enabling nano-silver powder and antistatic substances to adhere stably to the surface of polyester fibers, ensuring the antistatic effect of the finished quick-drying fabric.

[0028] Secondly, this application provides a method for preparing quick-drying fabric, which adopts the following technical solution: A method for preparing a quick-drying fabric includes the following steps: S1. Polyester chips, toughening fibers, porous fillers, compatibilizers, dispersants and lubricants are mixed evenly, and then melted, spun, stretched and shaped to obtain polyester fibers; S2. Polyester fiber and lyocell fiber are blended to obtain warp yarn, and polyester fiber and cotton fiber are blended to obtain weft yarn. The warp yarn and weft yarn are subjected to antistatic treatment to obtain antistatic warp yarn and antistatic weft yarn respectively. S3, antistatic warp yarns and antistatic weft yarns are woven together to obtain the finished fabric.

[0029] By adopting the above technical solution, polyester fibers are first prepared, then blended with lyocell fibers, and finally sprayed with an antistatic composite liquid, so that the finished fabric has the advantages of being soft, breathable, flexible, and antistatic.

[0030] In summary, this application has the following beneficial effects: 1. The warp yarns are made of polyester and lyocell fibers, and the weft yarns are made of polyester and cotton fibers. The natural cellulose structure of lyocell fibers gives the fabric a silk-like smooth feel. Its surface smoothness reduces the coefficient of friction with the skin, balancing the friction of polyester fibers against the skin and improving the skin-friendly and soft effect of quick-drying fabrics. Combined with the soft feel of cotton fibers, the softness of the fabric is further improved. The nano-sized pores of lyocell fibers can quickly absorb sweat. Combined with the moisture-wicking effect of cotton fibers and the grooved structure of polyester fibers, which can conduct moisture to the outer layer of the fabric for evaporation through capillary effect, the two are blended to form a two-way moisture-wicking network, improving the soft feel and breathability of the finished quick-drying fabric. In addition, after antistatic treatment, the antistatic effect of the finished quick-drying fabric can be improved.

[0031] 2. Polyester chips are compounded with toughening fibers, porous fillers, and other substances. The toughening fibers enhance the flexibility of the polyester fibers by providing bonding and toughening effects. The porous fillers improve the breathability of the quick-drying fabric by enhancing the porous breathability of the fabric. Compatibilizers are added to improve the compatibility and bonding between the toughening fibers, porous fillers, and polyester chips. Dispersants are added to ensure that the toughening fibers and porous fillers are evenly dispersed and in uniform contact with the polyester chips, thereby uniformly improving the flexibility and breathability of the polyester fibers. Lubricants are added to facilitate the extrusion molding of polyester fibers and ensure the quality of the polyester fibers. As a result, the prepared quick-drying fabric has good flexibility and good breathability.

[0032] 3. Under the conditions of a spinneret diameter of 0.2mm and a stretch ratio of 6, the average diameter of polyester fiber is about 15-18μm. By limiting the amount of toughening fiber and porous filler added, the toughening fiber and porous filler can be evenly dispersed while ensuring the mechanical properties and structural stability of polyester fiber. This allows for the spinning of quick-drying fabrics and extends their service life. Detailed Implementation

The softness of the fabrics was tested based on the hand feel evaluation. The scoring criteria were as follows: 10 points for high hand softness → 0 points for stiff and not soft hand feel. The data were recorded.

[0066] 3. Breathability test Finished fabrics were prepared using the methods described in Examples 1-3 and 6-8, respectively, and the air permeability data were recorded with reference to GB / T 5453.

[0067] 4. Flexibility test Polyester fibers were prepared using the methods described in Examples 1-8, and the elongation at break of the polyester fibers was tested according to GB / T 3923.1, and the data were recorded.

[0068] 5. Antistatic property testing Finished fabrics were prepared using the methods of Example 1 and Comparative Example 2, respectively. The volume resistivity was measured using a Jiahong-02 resistivity meter from Dongguan Jiahong Antistatic Technology Co., Ltd., and the data were recorded.

[0069] Table 2 Performance Test Table (In the table, " / " represents the corresponding example and comparative example where no corresponding item was tested and no data is displayed) As can be seen from Examples 1-3 and Table 2, the fabric prepared in this application has a soft and comfortable effect, good breathability, and high elongation at break, indicating good flexibility, while also having a good antistatic effect.

[0070] Combining Examples 1 and 4-8 with Table 2, it can be seen that in the preparation of toughened fiber in Example 4, the modified carbon fiber was replaced with the same mass of carbon fiber. Compared with Example 1, the elongation at break in Example 4 was lower than that in Example 1. This indicates that the adhesion of polybutylene succinate to the surface of carbon fiber can improve the crosslinking compatibility between carbon fiber and polyester matrix. Combined with the flexibility of polybutylene succinate, the flexibility of polyester fiber is improved, thereby improving the mechanical properties of the fabric.

[0071] In Example 5, the modified silica fiber was replaced with silica fiber of the same mass during the preparation of the toughening fiber. Compared with Example 1, the elongation at break of Example 5 was lower than that of Example 1. This indicates that the organosilicon-modified acrylic resin on the surface of the silica fiber can be connected with the polyester matrix, modified carbon fiber and other materials, and can impart a certain degree of toughness, thereby improving the flexibility of the polyester fiber and giving the fabric better quality.

[0072] In Example 6, the cellulose nanofibers were replaced with carbon fibers of the same mass during the preparation of the toughening fiber. Compared with Example 1, the air permeability of Example 6 was worse than that of Example 1, and the elongation at break was lower than that of Example 1. This indicates that the cellulose nanofibers have good flexibility and a certain degree of air permeability, which gives the polyester fiber a certain degree of air permeability and toughness, thus giving the fabric good air permeability and good toughness.

[0073] In Example 7, the molecular sieve composite material was replaced with the same mass of molecular sieve during the preparation of the porous filler. Compared with Example 1, the air permeability of Example 7 was worse than that of Example 1, and the elongation at break was lower than that of Example 1. This indicates that the presence of polycaprolactone and polyvinyl alcohol solution on the surface of the molecular sieve can not only promote the connection between the molecular sieve and the polyester matrix, but also increase the porosity and ensure the air permeability of the polyester fiber, thereby giving the fabric a certain air permeability.

[0074] In Example 8, during the preparation of the porous filler, the hydrophobic silica microparticles were replaced with silica microspheres of the same mass. Compared with Example 1, the air permeability of Example 8 was worse than that of Example 1, and the elongation at break was lower than that of Example 1. This indicates that silica microspheres do not have the flexibility of silica microparticles, while hydrophobic silica microparticles can improve the flexibility of polyester fibers, giving the fabric better mechanical properties. Furthermore, silica microspheres do not contain a porous structure, which affects air permeability.

[0075] Combining Example 1 and Comparative Examples 1-2 with Table 2, it can be seen that in Comparative Example 1, the fabric was made by replacing Lyocell fiber with the same mass of polyester fiber and cotton fiber with the same mass of polyester fiber, that is, both the warp and weft were polyester fiber. Compared with Example 1, the score of Comparative Example 1 was lower than that of Example 1; indicating that the fabric made of ordinary polyester fiber affects the softness of the fabric.

[0076] Comparative Example 2, without the addition of antistatic composite liquid, showed a higher volume resistivity than Example 1, indicating that the addition of antistatic composite liquid can improve the antistatic properties of the fabric.
