Description

Technical Field

[0001] This application relates to the field of textile fabric technology, specifically to a high moisture-wicking sports fabric. Background Technology

[0002] With the development of functional textiles, people are increasingly demanding greater comfort in clothing while maintaining its functionality. Sportswear and casual wear, due to their high comfort level, have gradually become mainstream categories in the market and are increasingly popular among consumers. Comfort and functionality have become key factors for clothing manufacturers to gain a competitive edge in the market. The themes of clothing and textile trends have shifted from simple style to a focus on moisture and tactile comfort. This places higher demands on the moisture-wicking properties of clothing fabrics, ensuring that clothing does not stick to the skin and create a damp, cold feeling when the body is sweating.

[0003] Currently, most sportswear fabrics are made of polyester fiber. Polyester fiber has high crystallinity and excellent wrinkle resistance, resilience, fabric crispness, abrasion resistance, insect resistance, oxidation resistance, and friction resistance. It has long been a commonly used substitute for natural fibers and is widely used in clothing and many other fields. However, polyester molecules do not have hydrophilic groups on their main chain, making them hydrophobic fibers. Furthermore, their tightly packed molecular structure makes it difficult for sweat to be absorbed into the fiber, resulting in poor moisture absorption and wicking properties. This can lead to a stuffy feeling and generally lower comfort levels. Summary of the Invention

[0004] In order to enable polyester fiber to be used as a sports fabric, while maintaining high elasticity and fabric crispness, it also has high moisture-wicking properties, good breathability, and good hand feel. This application provides a sports fabric with high moisture-wicking properties.

[0005] A highly moisture-wicking sports fabric includes moisture-wicking fibers, lyocell fibers, and collagen fibers, wherein the moisture-wicking fibers are made of modified polyester and polyamide, and the modified polyester is prepared by the following steps:

[0006] The grafted double bond polyester is dispersed in an organic solvent, and a mercapto compound and an initiator are added to prepare a reaction system. The temperature is raised to 50-60℃, and the polymerization reaction is carried out for 10-16 hours. After filtration, washing, and drying, the modified polyester is obtained.

[0007] By employing the above technical solution, and through a composite blending of moisture-wicking fibers with lyocell fibers and collagen fibers, the moisture-wicking properties of polyester sportswear are enhanced. First, carbon-carbon double bonds are grafted onto the polyester. Then, a thiol compound and an initiator are added. A thiol-alkenyl reaction occurs between the thiol compound and the carbon-carbon double bonds. The hydrophilic thiol compound crosslinks onto the polyester through polymerization, giving the polyester permanent hydrophilic properties. The modified polyester is then mixed with polyamide and extruded to produce moisture-wicking fibers.

[0008] Polyamide has good moisture absorption and excellent abrasion resistance, and it is also lightweight, making it highly comfortable to wear. By blending polyester and polyamide, sports fabrics combine the characteristics of each fiber, maximizing their advantages and minimizing their disadvantages, thus broadening the fabric's versatility.

[0009] By combining moisture-wicking fibers with lyocell and collagen fibers, the fabric achieves both absorbency and quick-drying properties. This prevents sportswear from clinging to the skin and causing a damp, cold feeling, while enhancing the absorbency of the composite fibers. The moisture-wicking fibers absorb sweat from the skin, while the moisture-wicking fibers quickly guide the sweat to the fabric's surface and release it into the air, keeping the clothing dry.

[0010] In one specific implementation, the preparation method of the grafted double bond polyester includes the following steps: dispersing 5-10 parts by weight of alkali-treated polyester into 90-100 parts by weight of dichloromethane, adding 0.8-1.2 parts by weight of γ-methacryloyloxypropyltrimethoxysilane, heating to 40-60°C and reacting for 2-3 hours, filtering, and obtaining the grafted double bond polyester.

[0011] By employing the above technical solution, under alkaline conditions, the ester groups in the polyester fiber molecular chain undergo a hydrolysis reaction, leading to molecular chain breakage and achieving micro-hydrolysis of the polyester. The alkali-treated polyester is dispersed in a polar solvent, and then γ-methacryloyloxypropyltrimethoxysilane containing double bonds is added. After hydrolysis, γ-methacryloyloxypropyltrimethoxysilane contains silanol groups, which can react with the active groups on the polyester surface, thereby grafting and polymerizing the carbon-carbon double bonds onto the polyester chain.

[0012] In one specific embodiment, the thiol compound includes one or more of sulfonated thiol acids, mercaptopropionic acid, mercaptoacetic acid, mercaptoethanol, and cysteine.

[0013] By adopting the above technical solution, the thiol compound is crosslinked onto the polyester grafted with carbon-carbon double bonds through the reaction between hydrophilic thiol compound molecules and carbon-carbon double bonds, so as to achieve permanent hydrophilicity of the polyester. The crosslinking of the thiol compound on the surface of the polyester greatly enhances the overall hydrophilicity of the polyester.

[0014] In one specific implementation, the initiator is azobisisobutyronitrile (AIBN), and the organic solvent is dimethyl sulfoxide (DMSO).

[0015] By employing the above technical solution, the pyrolysis of azobisisobutyronitrile (AIBN) generates methylene radicals. These methylene radicals react with thiol groups to form thiol radicals. The thiol radicals then react with carbon-carbon double bonds to form alkyl radicals. These alkyl radicals further react with thiol compounds, thus allowing the reaction to proceed continuously. Dimethyl sulfoxide (DMSO) exhibits high polarity, good solubility, and high stability, which can promote the reaction.

[0016] In one specific implementation, the weight ratio of the grafted double bond polyester, the thiol compound, and the initiator is 1:(0.5-0.8):(0.01-0.09).

[0017] By adopting the above technical solution, in the graft polymerization reaction, a certain proportion of double bonds and mercapto groups react, and then the polymerization reaction is initiated by a free radical initiator to form a more stable water-absorbing crosslinked structure, thereby further improving the water absorption and wettability of polyester.

[0018] In one specific implementation, the mass ratio of the modified polyester to polyamide is 100:10-15.

[0019] By adopting the above technical solution, by compounding hydrophilic modified polyester and moisture-absorbing and wear-resistant polyamide in a certain proportion, their respective excellent properties can be fully utilized, so that the sports fabric has high elasticity, crispness and shape, light weight and wear resistance. More importantly, the fabric has stronger moisture absorption, which can absorb the moisture generated on the skin surface in time, thereby keeping the fabric in contact with the body dry and making the human body feel comfortable.

[0020] In one specific feasible implementation, the fineness of the moisture-absorbing fiber is 40-60D.

[0021] By adopting the above technical solution, the fineness of the fibers is adjusted to regulate the surface area of ​​contact between the fibers and the skin, thereby better utilizing the moisture-wicking properties of the fibers. The micropores or grooves on the surface of the moisture-wicking fibers, utilizing capillary action, allow the fibers to quickly absorb moisture and sweat from the skin's surface and release it to the outer layer for evaporation. This more timely absorption and faster diffusion of water avoids the damp and cold feeling that sports fabrics experience after absorbing water, enhancing the fabric's comfort and warmth retention properties.

[0022] In one specific implementation, the polyamide is any one or more of PA6, PA66, and PA610.

[0023] By adopting the above technical solution and combining polyamide chips with different properties, the high strength and high load requirements of sports fabrics are guaranteed, so that the fabric has high strength, abrasion resistance, UV resistance, durability and good tensile strength, thereby enhancing the overall performance of sports fabrics.

[0024] In one specific implementation, the method for preparing the collagen fibers includes the following steps:

[0025] Collagen solution was prepared by dissolving collagen in an aqueous solution of N-methyldiethanolamine at a mass ratio of 1:25-30. After centrifugation and degassing, collagen gel fibers were prepared by wet spinning. After drying, collagen fibers were obtained.

[0026] The N-methyldiethanolamine aqueous solution contains 0.08-0.1 wt% N-methyldiethanolamine, has a pH of 3-5, and has a collagen fiber fineness of 80-100D.

[0027] By adopting the above technical solutions, the composition of regenerated collagen fibers is highly similar to that of human skin tissue, providing moisturizing, nourishing, firming, anti-wrinkle, and repairing effects. Collagen fibers also possess excellent biocompatibility, allowing them to transfer moisture to the fabric surface through infiltration and conduction. Therefore, regenerated collagen fibers not only give sportswear fabrics good smoothness and elasticity but also excellent moisture absorption and wicking properties.

[0028] In one specific implementation, the sports fabric is a blend of moisture-wicking fibers, lyocell fibers, and collagen fibers in a mass ratio of 100:(25-35):(5-15).

[0029] By adopting the above technical solution, Lyocell fiber, whose main component is natural fiber, has the warmth of wool, does not generate static electricity, is hypoallergenic, and has a glossy surface. In terms of washing, it is also anti-pilling and has a very low shrinkage rate. In addition, it has a stronger water molecule binding ability, which makes up for the defects of polyester such as easy static electricity, fabric pilling, and hydrophobicity.

[0030] By blending moisture-wicking fibers, collagen fibers, and lyocell fibers in a specific ratio, sports fabrics possess both moisture-wicking and quick-drying properties. The blend of moisture-wicking and collagen fibers maintains high elasticity, a crisp texture, wrinkle resistance, and skin-friendliness, while also providing water absorption and quick-drying properties. The addition of lyocell fibers enhances the fabric's luster, reduces static electricity and pilling, and significantly improves its moisture absorption and wicking properties. The moisture-wicking fibers absorb sweat from the skin, while the wicking fibers quickly guide sweat to the fabric's surface and release it into the air. During exercise, the sports fabric rapidly absorbs sweat from the skin and quickly conducts it to the outer surface of the fabric for evaporation, keeping the skin dry and comfortable.

[0031] In summary, this application includes at least one of the following beneficial technical effects:

[0032] 1. By employing a composite blend of moisture-wicking fibers and lyocell and collagen fibers with moisture-wicking properties, the moisture-wicking performance of polyester sportswear fabrics is enhanced. First, after alkali treatment, hydrophilic polyester is grafted with carbon-carbon double bonds. Then, thiol compounds and free radical reaction initiators are added. The thiol compounds react with the carbon-carbon double bonds, and the hydrophilic thiol compounds crosslink onto the polyester, giving it permanent hydrophilic properties. Next, moisture-wicking fibers are produced through melt co-extrusion of polyester and polyamide. By combining the moisture-wicking and moisture-wicking fibers, the moisture-wicking fibers absorb sweat from the skin, while the moisture-wicking fibers quickly guide sweat to the fabric surface and promptly release moisture into the air. During exercise and sweating, the fabric can absorb and evaporate moisture in a timely manner, keeping the skin surface dry and providing comfort.

[0033] 2. Utilizing the similarity between regenerated collagen fibers and human skin tissue, and their excellent biocompatibility, these fibers absorb and transfer moisture to the fabric surface through infiltration and conduction. Regenerated collagen fibers enhance the smoothness and elasticity of sports fabrics, making them soft and skin-friendly, while also giving the fabric excellent moisture absorption and wicking properties.

[0034] 3. By utilizing the reaction between hydrophilic thiol compound molecules and carbon-carbon double bonds, thiol compounds are crosslinked onto polyesters grafted with carbon-carbon double bonds to achieve permanent hydrophilicity of the polyester. The thiol compounds crosslink with each other on the surface of the polyester, greatly enhancing the overall hydrophilicity of the polyester. Detailed Implementation

[0206] Table 1 Performance Test Results

[0207]

[0208]

[0209] By comparing Examples 1-6 and Comparative Example 1, it can be seen that the sports fabric in Comparative Example 1 is inferior to the high moisture-wicking sports fabric prepared in Examples 1-6 in terms of moisture absorption, breathability, and fabric breaking elongation. Analysis of Examples 5 and Comparative Example 1 suggests that the polyester may have undergone hydrophilic modification to facilitate the grafting of carbon-carbon double bonds, which then undergoes a mercapto-alkenyl click reaction with mercapto compounds. The hydrophilic mercapto compounds then polymerize and crosslink onto the polyester, achieving permanent hydrophilicity and greatly enhancing the overall hydrophilicity of the polyester.

[0210] Comparing Examples 5, 9-11, and Comparative Example 4, it is evident that the sports fabric prepared in Example 11 exhibits significantly weaker moisture absorption, breathability, and elongation at break. Analysis suggests that Examples 4-6, through wet spinning, coagulate collagen solutions into collagen fibers with a triple-helix structure, resulting in continuous, non-adhesive collagen threads with better moisture absorption and breathability. In contrast, the threads obtained in Example 7 are too fine, resulting in a smaller contact area with the skin and weaker moisture absorption, leading to a weaker strength in the resulting blended sports fabric. The sports fabric in Comparative Example 4, in terms of moisture absorption, breathability, strength, and elasticity, is inferior to that of Examples 5 and 9-11. The highly moisture-wicking sports fabric prepared in Comparative Example 4 utilizes regenerated collagen fibers, which have moisturizing, nourishing, firming, anti-wrinkle, and repairing effects on human skin, exhibiting good biocompatibility and transferring moisture to the fabric surface through infiltration. By utilizing the super-high moisture absorption, capillary action, and hydrophilicity of collagen fibers, the moisture-wicking performance of the fabric is greatly improved. However, excessive addition leads to a significant decrease in its mechanical properties.

[0211] Comparing Example 5 with Examples 12-13, it can be seen that the sports fabric prepared in Example 13 has significantly weaker moisture absorption, breathability, and elongation at break. Analysis suggests that a certain blending ratio of modified polyester and polyamide in the moisture-absorbing fiber is appropriate. A higher polyamide content has an adverse effect on the moisture absorption and breathability of the fabric, and the elongation at break of the fabric will also be significantly reduced.

[0212] Comparing Examples 5, 14-16, and Comparative Example 3, it can be concluded that by combining moisture-absorbing fibers with hydrophilic and moisture-wicking lyocell fibers and collagen fibers, the moisture absorption and breathability of the fabric are greatly enhanced. During exercise and sweating, moisture is absorbed promptly, keeping the skin surface dry and providing comfort. The modified polyester and polyamide, combined in a certain proportion, can fully utilize their respective excellent properties, resulting in sports fabrics that are highly elastic, crisp, lightweight, and abrasion-resistant, enhancing the mechanical properties of the fabric. The capillary action of the lyocell and collagen fibers significantly improves the overall moisture absorption and wicking performance of the composite fabric, greatly improving its moisture absorption and air release properties. Examples 15 and 16 show that excessively high or low proportions of modified polyester, lyocell, and collagen fibers are not recommended. A small amount of lyocell fiber or an excessive amount of collagen fiber may not achieve the desired crispness, comfort, skin-friendliness, anti-static properties, and pilling resistance, and will also significantly reduce moisture absorption and wicking performance.

[0213] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
