Description

Technical Field

[0001] The present application relates to the field of fabric processing, and more specifically, to a breathable and moisture-conducting fabric and its preparation method and application. Background Art

[0002] In the textile industry, the development of breathable and moisture-wicking fabrics has always been a key focus for enhancing wearer comfort. With people's growing pursuit of health and comfort, breathable and moisture-wicking fabrics have attracted significant attention for their excellent moisture-wicking properties. Textile technology has made significant advances, significantly enhancing the fundamental functionality of fabrics through improvements in fiber materials and weaving processes. However, with evolving consumer demands, maintaining breathability while further improving moisture-wicking properties has become a pressing challenge.

[0003] To address this challenge, existing technologies focus on two main areas: first, by changing the physical form of the fiber, such as by designing fiber cross-sections with profiles or hollow or porous fibers, to increase the specific surface area and thus improve sweat evaporation efficiency; second, by chemically modifying the fiber surface to make it hydrophilic, thereby enhancing its moisture absorption capacity. In addition, some technologies attempt to print water-conducting patterns on the surface of the fabric to guide sweat out quickly, but this method often affects the overall aesthetics and durability of the fabric.

[0004] While the aforementioned technologies have addressed the issue of breathability and moisture conduction to a certain extent, they still have some significant drawbacks. For example, while modifying the physical form of fibers can improve moisture conduction, in practice, the complexity of the fiber structure often causes discomfort on the skin-facing surface, especially during prolonged wear. Furthermore, while surface modification can enhance moisture absorption, its relatively low evaporation rate cannot meet the demands of high-intensity exercise or high-temperature environments.

[0005] Furthermore, while printing water-conducting patterns can improve moisture conduction, they are susceptible to wear and tear due to sweat and friction during use. Furthermore, the printed water-conducting patterns can also easily fall off after repeated washings, resulting in poor durability and shortening the product's lifespan. Therefore, developing a moisture-conducting fabric that combines excellent moisture conduction performance with high durability has become a current research focus. Summary of the Invention

[0006] In order to reduce the phenomenon of fabric falling off during use and at the same time achieve better moisture conduction effect, the present application provides a breathable moisture conduction fabric and its preparation method and application.

[0007] In a first aspect, the present application provides a breathable and moisture-conducting fabric, comprising a polyester hydrophobic body, the polyester hydrophobic body being woven from polyester fiber yarns, one side of the polyester hydrophobic body being provided with a moisture-conducting pattern layer, the moisture-conducting pattern being formed by printing and curing a moisture-conducting coating, the moisture-conducting coating being composed of the following raw materials in parts by weight: Polyethylene glycol methyl ether methacrylate 1-8% Epoxidized soybean oil acrylate 1-5% Emulsifier 0.1-0.5% Initiator 0.03-0.08% Polyhydroxy acrylate 3-8% Water-absorbing filler 5-15% The balance is solvent; The water-absorbing filler is composed of polysaccharide fiber powder and PHA powder in a weight ratio of 1: (0.5-1).

[0008] Polysaccharide fiber powder and PHA powder are compounded in a specific ratio to fully utilize their respective water absorption properties while maintaining good dispersibility and stability. This combination not only improves the overall moisture absorption capacity of the moisture-conducting coating, but also enhances the washability and abrasion resistance of the moisture-conducting pattern layer, allowing it to maintain its moisture-conducting effect longer-lasting in actual use. Specifically, the synergistic effect of polysaccharide fiber powder and PHA powder can form a uniform and stable moisture-conducting layer on the surface of the hydrophobic polyester base, effectively improving the fabric's unidirectional moisture-conducting properties, reducing discomfort on the skin-contacting surface, and enhancing wearing comfort.

[0009] Furthermore, polysaccharide fiber powder and PHA powder possess excellent moisture absorption properties and interact with polyethylene glycol methyl ether methacrylate, epoxy soybean oil acrylate, and polyhydroxy acrylate to form a uniformly dispersed raw material system for moisture-conducting coatings. The synergistic effect of polyethylene glycol methyl ether methacrylate, epoxy soybean oil acrylate, and polyhydroxy acrylate not only improves the uniformity of the water-absorbing filler dispersion within the raw material system but also, under the action of the initiator, forms a cross-linked network of macromolecular polymers, ensuring stable adhesion of the moisture-conducting pattern layer formed after curing to the surface of the hydrophobic polyester base.

[0010] The moisture-conducting pattern layer also possesses excellent moisture absorption, washability, sweat corrosion resistance, and abrasion resistance, enabling it to quickly absorb and conduct moisture, while preventing corrosion from sweat during use or shedding during washing. This ensures the fabric's long-term moisture conduction and durability. Because the polyester hydrophobic base is made of polyester fiber, it possesses excellent hydrophobicity. This, combined with the moisture-conducting pattern layer, creates a differential moisture absorption on both sides of the fabric, enabling unidirectional moisture conduction. Consequently, moisture is quickly channeled through the moisture-conducting pattern layer to the outer layer, enhancing the fabric's overall moisture conduction performance.

[0011] Preferably, the thickness of the pattern layer is 1-20 microns.

[0012] By adopting this technical solution, the thickness of the pattern layer is controlled within the range of 1-20 microns, making it more skin-friendly and reducing skin irritation while maintaining good moisture conduction. This thickness selection not only improves the fabric's moisture conduction function but also ensures that the pattern layer is not easily worn during use, extending the fabric's service life.

[0013] Furthermore, the moisture-conducting pattern layer is composed of a number of hexagonal lines, which has a better water absorption effect and quickly diffuses water, thereby promoting moisture conduction of the fabric. Figure 1 shown.

[0014] Preferably, the polyester fiber yarn is 40-80 count, and the weight of the polyester hydrophobic body is 80-120 g / m 2 .

[0015] By adopting the above technical solution, the polyester fiber yarn is selected to be 40-80, and the weight of the polyester hydrophobic body is selected to be 80-120g / m 2 , giving the polyester hydrophobic base excellent hydrophobic and breathable properties. This selection facilitates the formation of a stable moisture-wicking pattern layer on its surface, improving the fabric's overall moisture-wicking properties. Furthermore, this polyester yarn specification and weight of the polyester hydrophobic base are less susceptible to wear during use, ensuring the fabric's long-term durability and comfort.

[0016] Preferably, the polysaccharide fiber powder is chitosan fiber powder and / or seaweed fiber powder.

[0017] By adopting the above technical solution, chitosan fiber powder and / or seaweed fiber powder, as water-absorbing fillers, have excellent water absorption and biocompatibility, and can be evenly dispersed in the moisture-conducting coating to form a stable moisture-conducting pattern layer. This not only improves the moisture-conducting performance of the fabric, but also enhances the washability and abrasion resistance of the pattern layer, thereby ensuring the long-term use of the fabric. Furthermore, the chitosan fiber powder and seaweed fiber powder are skin-friendly, reducing skin irritation and improving wearing comfort.

[0018] Preferably, the particle size of the polysaccharide fiber powder is 20-100 nm, and the particle size of the PHA powder is 200-300 nm.

[0019] By adopting this technical solution, the polysaccharide fiber powder has a particle size of 20-100nm, and the PHA powder has a particle size of 200-300nm. These particle sizes complement each other to form a unique moisture-conducting structure, further achieving optimal water-conducting effects. Furthermore, the fine particle size facilitates the uniform dispersion of the water-absorbing filler in the moisture-conducting coating, improving the stability of the moisture-conducting pattern layer and ensuring its strong adhesion to the hydrophobic polyester surface, reducing the possibility of wear and tear.

[0020] Preferably, the polyhydroxy acrylate is phenyl glycidyl ether acrylate and / or polyethylene glycol monomethacrylate.

[0021] By adopting the above technical solution, the active groups contained in phenyl glycidyl ether acrylate and / or polyethylene glycol monomethacrylate react with polyethylene glycol methyl ether methacrylate and epoxy soybean oil acrylate to form a macromolecular cross-linked network binding compound, which has excellent adhesion and water and sweat resistance, and reduces the occurrence of wear and tear.

[0022] Preferably, the polyhydroxy acrylate is composed of phenyl glycidyl ether acrylate and polyethylene glycol monomethacrylate in a weight ratio of 1:(1-3).

[0023] By adopting this technical solution, the combined weight ratio of phenyl glycidyl ether acrylate and polyethylene glycol monomethacrylate is 1:(1-3), further improving the overall performance of the moisture-wicking coating. The synergistic effect of these two polyhydroxy acrylates not only enhances adhesion and water resistance, but also improves sweat resistance and reduces the likelihood of wear and tear on the moisture-wicking pattern layer, thereby ensuring the long-term moisture-wicking effect and durability of the fabric.

[0024] Preferably, the emulsifier is cocamidopropyl betaine and / or lauroylpropyl dimethyl betaine.

[0025] By adopting the above technical solution, the emulsifiers, cocamidopropyl betaine and / or lauroylpropyl dimethyl betaine, not only provide excellent emulsification, dispersing, and wetting properties, allowing the moisture-conducting coating to easily wet the polyester hydrophobic body and improve its adhesion to the surface of the polyester hydrophobic body, but also copolymerize with other active components of the moisture-conducting coating to form macromolecular substances, significantly improving the overall performance of the moisture-conducting pattern layer, including better adhesion, water resistance, and sweat corrosion resistance, reducing the possibility of wear and tear of the moisture-conducting pattern layer, thereby ensuring the long-term moisture-conducting effect and durability of the fabric. It also promotes the uniform dispersion of water-absorbing fillers, further improving moisture-conducting performance.

[0026] In a second aspect, a method for preparing a breathable and moisture-conducting fabric comprises the following steps: Moisture-conducting coating: polyethylene glycol methyl ether methacrylate, epoxy soybean oil acrylate, emulsifier, initiator, polyhydroxy acrylate, water-absorbing filler, and solvent are weighed and mixed uniformly according to weight percentage to obtain a moisture-conducting coating; Polyester hydrophobic body: knitted from polyester fiber yarn; The moisture-conducting coating is printed on the surface of the polyester hydrophobic body, and after curing, a moisture-conducting pattern layer is formed on the surface of the polyester hydrophobic body to obtain a breathable and moisture-conducting fabric.

[0027] By adopting the above technical solution, polyethylene glycol methyl ether methacrylate, epoxy soybean oil acrylate, emulsifier, initiator, polyhydroxy acrylate, water-absorbing filler and solvent are evenly mixed to form a uniformly dispersed moisture-conductive coating; the polyester hydrophobic body is obtained by knitting, so it has hydrophobic and breathable effects. The moisture-conductive coating is printed on the surface of the polyester hydrophobic body by printing, and the thickness of the moisture-conductive pattern layer formed on the surface of the polyester hydrophobic body can be accurately controlled to avoid excessive thickness to produce an abrupt feeling and affect the overall appearance.

[0028] At the same time, during the curing process, its active ingredients, under the action of the initiator, form a cross-linked network of macromolecular polymers, so that the moisture-conducting pattern layer forms a stable film on the surface of the polyester hydrophobic body, effectively avoiding problems such as wear, water washing resistance and salt corrosion resistance, thereby ensuring the long-term moisture-conducting effect and durability of the fabric.

[0029] Thirdly, an application of a breathable and moisture-conducting fabric is provided, wherein the breathable and moisture-conducting fabric is cut and made into underwear.

[0030] By employing this technical solution, breathable, moisture-wicking fabrics are cut and manufactured into close-fitting garments. These fabrics exhibit excellent breathability and unidirectional moisture-wicking properties, effectively and quickly conducting sweat to the outer layer for evaporation, keeping the skin dry and comfortable. Furthermore, the moisture-wicking patterned layer exhibits excellent resistance to washing, abrasion, and sweat corrosion, ensuring that the garment maintains excellent moisture-wicking properties and aesthetic appearance even during prolonged use.

[0031] In summary, this application includes at least one of the following beneficial technical effects: 1. The polyethylene glycol methyl ether methacrylate, epoxy soybean oil acrylate and polyhydroxy acrylate in the moisture-conducting coating work synergistically to form a macromolecular cross-linked network structure under the action of the initiator, which significantly improves the washability and wear resistance of the moisture-conducting pattern layer, avoids the problem of easy falling off, and extends the service life of the fabric.

[0032] 2. The combination of the polyester hydrophobic body and the moisture-conducting pattern layer achieves a one-way moisture-conducting effect, that is, sweat is quickly transferred from the skin-contacting surface to the outside and evaporates without seeping back to the skin-contacting surface, thereby reducing discomfort on the skin-contacting surface and improving wearing comfort.

[0033] 3. The water-absorbing filler polysaccharide fiber powder and PHA powder are compounded and coordinated with polyethylene glycol methyl ether methacrylate, epoxy soybean oil acrylate and polyhydroxy acrylate. They are evenly dispersed in the moisture-conducting coating, which enhances the moisture absorption capacity and moisture-conducting effect of the moisture-conducting pattern layer and improves the applicability of the fabric in high-intensity exercise or high-temperature environments.

[0054] Application Examples Application Example 1 An application of a breathable and moisture-conducting fabric, wherein the breathable and moisture-conducting fabric obtained in Example 1 is cut into a close-fitting garment. When worn, the moisture-conducting pattern layer is close to the human body. The moisture-conducting pattern layer on the close-fitting garment is specifically as follows Figure 1 When the underwear comes into contact with water, the moisture-conducting pattern layer on the underwear shows a more obvious water absorption phenomenon, as shown in FIG. Figure 2-4 As shown in the figure, when the side of the close-fitting garment containing the moisture-conducting pattern layer just comes into contact with water, the moisture-conducting pattern layer immediately absorbs water. After 10 seconds of contact, the absorbed water from the moisture-conducting pattern layer begins to gradually spread to the surrounding area. At the same time, the surface without the moisture-conducting pattern layer also absorbs water. After 30 seconds, the water absorption and diffusion area increases, thereby achieving a better moisture-conducting effect.

[0055] Test method / test method Water absorption: refer to GB / T 21655.2-2019, test the water absorption efficiency of moisture absorption and perspiration before washing and moisture absorption and perspiration after washing, as shown in Table 2; Washing fastness: Refer to JIS L0844 A-2 for testing and obtain the corresponding grade; Sweat fastness: refer to JIS L0848 for testing and obtain the corresponding grade; Abrasion fastness: Refer to JIS L0849 wet friction and conduct testing to obtain the corresponding grade.

[0056] The above experimental data are shown in Table 2. Table 2 Experimental data of Examples 1-16 and Comparative Examples 1-4 Combining Example 1 and Comparative Examples 1-4 and Table 2, it can be seen that the water absorption efficiency of the moisture absorption and perspiration removal before and after washing of Comparative Examples 1-4 is lower than that of Example 1, and the levels of water fastness, sweat fastness, and abrasion fastness are also lower than those of Example 1. This shows that the present application uses polyethylene glycol methyl ether methacrylate, epoxy soybean oil acrylate, and polyhydroxy acrylate to enhance the water-absorbing filler, so that the water-absorbing filler can be dispersed more evenly, and a special water-absorbing structure is formed in the raw material embodiment, thereby improving the moisture-conducting effect, and the adhesion is stable after film formation, avoiding sweat erosion, friction shedding, or water-based shedding, thereby improving its durability.

[0057] Comparing Example 1, Example 6 and Example 7 and combining with Table 2, it can be seen that the water absorption efficiency of Example 1 and Example 6 is lower than that of Example 7, indicating that the chitosan fiber powder and seaweed fiber powder play a synergistic role, further promoting water absorption and moisture conduction.

[0058] By comparing Example 1, Example 8, and Example 9 and combining Table 2, it can be seen that the water absorption efficiency of Example 1 and Example 8 is lower than that of Example 9, and the washing fastness, sweat fastness, and abrasion fastness of Example 9 are higher than those of Example 1 and Example 8. The use of phenyl glycidyl ether acrylate and polyethylene glycol monomethacrylate plays a synergistic role, further improving the overall performance.

[0059] Comparing Example 1, Example 11, Example 12, and Example 13 with Table 2, it can be seen that Example 13 uses cocamidopropyl betaine and lauroylpropyl dimethyl betaine for compounding, and uses phenyl glycidyl ether acrylate and polyethylene glycol monomethacrylate to obtain a polyhydroxy acrylate, which interact with each other to enhance the overall performance.

[0060] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but as long as they are within the scope of the claims of the present application, they are protected by the patent law.
