Description

Technical Field

[0001] This invention belongs to the field of clothing technology, and in particular relates to a manufacturing process for a single-layer absorbent and breathable comfortable fabric and a shirt. Background Technology

[0002] In summer, shirts and T-shirts are the most commonly worn clothing. As we all know, in the hot summer, the temperature is very high and people sweat easily. After the sweat dries, sweat stains will appear on the clothes. Sweat stains are white and have obvious edge marks, which will affect the appearance of the clothing and make people feel embarrassed. Moreover, they can easily cause the clothes to yellow and greatly reduce the lifespan of the clothing. Existing technology for clothing is not very effective at preventing sweat stains. Summary of the Invention

[0003] This invention provides a manufacturing process for a single-layer absorbent and breathable comfortable fabric, aiming to solve the above-mentioned problems.

[0004] This invention is achieved through a manufacturing process for a single-layer waterproof and absorbent comfortable fabric, wherein the fabric comprises a hydrophilic inner layer and a hydrophobic outer layer, and the manufacturing process includes the following steps: To produce a hydrophilic inner layer yarn; To produce a hydrophobic outer layer yarn; The hydrophilic inner layer yarn and the hydrophobic outer layer yarn are woven into a fabric using existing conventional techniques, which will not be described in detail here. Completely immerse the fabric in clean water and rinse it 2-3 times, each rinsing time being 5-10 minutes. After washing, put the fabric into a spin dryer for 10-20 minutes to dehydrate it. After dehydration, take it out and lay it flat on a drying rack. The dehydrated fabric is placed in a dyeing vat for dyeing treatment, and then subjected to reduction cleaning. Both the dyeing treatment and reduction cleaning are performed using existing conventional techniques. The shape is set using a setting machine, employing existing conventional technology; The finished fabric is obtained by rolling and packaging the shaped fabric using a rolling machine.

[0005] Preferably, the hydrophilic inner layer comprises the following raw materials in parts by weight: 20-30 parts bamboo fiber, 3-7 parts modified spider silk fiber, 6-12 parts polylactic acid fiber, 2-6 parts chitosan fiber, 1-5 parts modified mannan, and 10-15 parts flax fiber.

[0006] Preferably, the hydrophilic inner layer comprises the following raw materials in parts by weight: 23-27 parts bamboo fiber, 4-6 parts modified spider silk fiber, 8-10 parts polylactic acid fiber, 3-5 parts chitosan fiber, 2-4 parts modified mannan, and 11-14 parts flax fiber.

[0007] Preferably, the hydrophilic inner layer comprises the following raw materials in parts by weight: 25 parts bamboo fiber, 5 parts modified spider silk fiber, 9 parts polylactic acid fiber, 4 parts chitosan fiber, 3 parts modified mannan, and 12.5 parts flax fiber.

[0008] Preferably, the modified spider silk fiber is prepared as follows: spider silk and hexafluoroisopropanol are mixed at a mass ratio of 1:4-6, and 0.1-0.2 times the mass of the spider silk dextran is added. The mixture is stirred to obtain a modified spider silk fiber spinning solution. The modified spider silk fiber spinning solution is electrospun to obtain modified spider silk fiber fibrils. The modified spider silk fiber fibrils are twisted to a linear density of 30-50 dtex, and then treated in a low-temperature plasma generator. The plasma stays on the fiber surface for 2-5 seconds to obtain modified spider silk fiber. By adding dextran and then performing low-temperature plasma treatment, the sweat absorption and breathability of the spider silk fiber are improved, and the modified spider silk fiber has good mechanical properties.

[0009] Preferably, the modified mannan is prepared as follows: glutamic acid, mannan and water are mixed evenly in a mass ratio of 1:8-12:60-80, and the mixture is heated under reflux at 90°C for 1-2 hours. Then, the mixture is concentrated and dried to obtain the modified mannan, which has good sweat absorption, breathability and antibacterial properties.

[0010] Preferably, the preparation of the hydrophilic inner layer yarn includes the following steps: bamboo fiber, polylactic acid fiber, chitosan fiber, and flax fiber are mixed evenly and placed in a sterile culture tank. Then, liquid culture medium and bacterial cellulose fermentation liquid are injected into the culture tank, sealed, and cultured at 25-30℃ for 2-3 days. The culture product is rinsed with deionized water to remove residual culture medium. After soaking in deionized water until colorless, it is filtered and dried for later use. The dried culture product is mixed with modified spider silk fiber and modified mannan and dried. After being processed by roving, spinning, automatic winding, steaming, and high-speed doubling, the yarn is obtained. During the fermentation process, bacterial cellulose grows into the bamboo fiber, polylactic acid fiber, chitosan fiber, and flax fiber, forming an interwoven network with a large storage space, improving sweat absorption and yarn mechanical properties.

[0011] Preferably, the preparation method of the bacterial cellulose fermentation broth is as follows: inoculate Acetobacter xylinum strain into the culture medium, at a temperature of 25-28℃, a stirring speed of 200-240 r / min, and a culture time of 24-36 h to obtain a seed liquid; add 10-15% of the volume of the seed liquid into the culture medium, mix well and set aside to obtain the bacterial cellulose fermentation broth.

[0012] Preferably, the hydrophobic outer layer comprises the following raw materials in parts by weight: 30-40 parts polyurethane, 10-20 parts polyethylene terephthalate, 1-2 parts aziridine crosslinking agent, 1-3 parts modified zein, and 1-3 parts quercetin.

The solution is heated to 40-50°C and stirred for 20-30 minutes. The sediment is separated by centrifugation, dried, and pulverized to obtain the modified zein. By adding fluorinated graphene and oleic acid, the hydrophobicity of the zein is improved, thereby enhancing the waterproof effect of the hydrophobic outer layer.

[0014] The present invention also provides a shirt made of a single-layer absorbent and breathable comfortable fabric manufactured using the above-described manufacturing process.

[0015] Compared with the prior art, the embodiments of this application have the following main advantages: The present invention provides a manufacturing process for a single-layer waterproof and single-layer absorbent comfortable fabric. The fabric comprises a hydrophilic inner layer and a hydrophobic outer layer. By producing hydrophilic inner layer yarn and hydrophobic outer layer yarn, the hydrophilic inner layer and hydrophobic outer layer are respectively made. The skin-contact layer is hydrophilic, quickly absorbs sweat, and evaporates quickly, making it more comfortable to wear. The outer layer is hydrophobic, preventing permeability in the reverse direction, forming a protective barrier, blocking sweat, and eliminating sweat marks. Modified spider silk fiber and modified mannan are added to the hydrophilic inner layer raw material, and the two work synergistically to greatly improve the fabric's moisture absorption and perspiration wicking effect. Modified corn gluten and quercetin are added to the hydrophobic outer layer raw material, and the two work synergistically to greatly improve the fabric's waterproof effect.
