Description

Technical Field

[0001] The invention relates to the technical field of air layer fabric preparation, and in particular to a method for preparing an ultraviolet resistant quick-drying air layer fabric. Background Art

[0002] Air layer fabric is a new type of functional fabric. It uses high-tech fiber manufacturing technology to weave fibers into a layer of cloth with a special air structure, making the fabric have the characteristics of "fluffy, soft, and warm". Air layer fabric is a kind of textile accessories. The pure cotton fabric is soaked in a chemical solution. After soaking, the surface of the fabric is covered with countless very fine hairs. These fine hairs can form a very thin air layer on the surface of the fabric; there is also a kind of fabric that is made by sewing two different fabrics together with a certain gap in the middle to form an air layer. This fabric not only has a good warming effect, but also has breathability and comfort.

[0003] Since an air layer is formed between the inner and outer fabrics of the air layer fabric, the air permeability is reduced. After people exercise, the inner layer of the air layer fabric absorbs sweat, but the moisture is not easy to evaporate, resulting in reduced comfort of wearing and causing physical discomfort. The existing air layer fabric is not ideal in terms of anti-ultraviolet effect, so there is a need for an anti-ultraviolet quick-drying air layer fabric. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a method for preparing an ultraviolet resistant quick-drying air layer fabric.

[0005] The technical solution of the present invention is: a method for preparing an ultraviolet resistant quick-drying air layer fabric, comprising the following steps:

[0006] S1, knitting the inner fabric yarn on the rear needle bed, knitting with alternate needles after every eight rows, and turning the loops formed by the alternate needle knitting onto the empty needles of the front needle bed;

[0007] S2, knitting the outer fabric yarn on the front needle bed, and knitting the original loops on the front needle bed and the loops turned to the front needle bed in step S1 into the outer fabric after every eight rows;

[0008] S3, repeating steps S1 and S2 to form a transverse circulation area, wherein the inner circulation area is a plain weft needle structure, and the outer circulation area is a pearl mesh structure, and the air layer blank is formed by circular weaving;

[0009] S4, dyeing, softening, washing, dehydrating and drying the air layer blank obtained in S3 in sequence to obtain a finished air layer fabric.

[0010] Furthermore, the inner fabric yarn is obtained by mixing cotton fiber and tencel fiber in a mass ratio of 1:2, and then combing, twisting and twisting.

[0011] Note: Cotton fiber has good moisture absorption and air permeability, while Tencel fiber has stronger moisture absorption. Mixed yarn inherits the advantages of both and can provide better wearing comfort.

[0012] Furthermore, the inner fabric yarn has a twist of 300-450 T / m, an s-twist direction, a tension of 15 cN, and a tex number of 18.5 Tex.

[0013] Description: Such twist can make the yarn have certain strength and elasticity, while maintaining good feel and gloss. Such design can make the yarn have certain tension, increase the wear resistance and durability of the yarn. At the same time, such tension can also make the yarn less likely to break during use, increasing the service life of the yarn.

[0014] Furthermore, the outer fabric yarn is obtained by mixing nylon fiber, bamboo fiber and polyester fiber in a mass ratio of 1:1:1, and then combing, twisting and twisting.

[0015] Description: Bamboo fiber, like cotton fiber, has good moisture absorption and air permeability, can help regulate the body's temperature and humidity, and provide a comfortable wearing experience. Polyester fiber has excellent wear resistance and durability, which makes the mixed yarn have a longer service life and better resistance to daily wear while maintaining the advantages of other fibers. Polyester fiber can improve the UV resistance of the outer fabric. Nylon fiber has excellent elasticity and recovery, which makes the mixed yarn quickly return to its original shape while maintaining a certain shape, making the outer fabric less prone to wrinkles.

[0016] Furthermore, the outer fabric yarn has a twist of 500-800 T / m, a twist direction of Z twist, a tension of 20 cN, and a Tex number of 14.5 Tex.

[0017] Note: The outer fabric has a higher twist than the inner fabric, so the outer fabric has higher wear resistance. High-twist yarns are not easy to shrink or deform. 14.5Tex yarns are of medium thickness and are suitable for making fabrics that have a certain thickness and warmth retention while maintaining good breathability, thus providing a comfortable wearing experience.

[0018] Furthermore, the beaded mesh organization method is to form a loop with two consecutive needles on the same longitudinal path, and to tuck two consecutive needles alternately, and eight paths and two needles complete a cycle.

[0019] Description: The above weaving method forms an outer fabric with mesh, which is conducive to the volatilization of moisture in the inner fabric and increases the air permeability, so that the air layer fabric has a quick-drying effect.

[0020] Furthermore, the dyeing treatment is to immerse the obtained air layer fabric in a chlorogenic acid aqueous solution and carry out ultrasonic treatment for 20-30 minutes, the mass concentration of the chlorogenic acid aqueous solution is 15-20%, the temperature of the chlorogenic acid aqueous solution is 30-40°C, the power of the ultrasonic treatment is 70-88W, the frequency is 100-120kHz, and then hot pressing and drying treatment is carried out until the moisture content of the air layer fabric reaches 8-10%, the temperature of the hot pressing and drying is 60-80°C, and the pressure is 0.13-0.15MPa, and then the air layer fabric is placed in an air-liquid dyeing machine for dyeing.

[0021] Description: Chlorogenic acid has significant antioxidant properties, which can help resist the damage of free radicals and slow down the aging process of fabrics. Chlorogenic acid has a certain antibacterial effect, which can inhibit the growth of bacteria and keep the fabrics clean and hygienic. Ultrasonic treatment is conducive to the contact between the chlorogenic acid solution and the air layer fabric.

[0022] Furthermore, the bath ratio of the gas-liquid dyeing machine during dyeing is 1:30, and the dye used for dyeing is composed of the following components in mass percentage: 40-50% natural pigment, 5-8% 2,4,6-tris(2'-n-butoxyphenyl)-1,3,5-triazine, 3-7% 2-(2'-hydroxy-3',5'-di-tert-phenyl)-5-chlorobenzotriazole, 3-5% oleic acid monoglyceride, 1-4% sodium decanol polyoxyethylene ether carboxylate, and the balance is water.

[0023] Description: Adding 2,4,6-tris(2'-n-butoxyphenyl)-1,3,5-triazine and 2-(2'-hydroxy-3',5'-di-tert-phenyl)-5-chlorobenzotriazole into dyeing agent can improve the anti-ultraviolet ability of fabric.

[0024] Furthermore, the single cleaning time is 10-15 minutes, the number of cleaning times is 2-3 times, and after cleaning, the water content is dehydrated to 3-5%, and the drying temperature is 70-80°C, and the drying is performed until there is no water.

[0025] Note: First wash to remove residual dyes and softeners from the air layer fabric, then quickly remove moisture through dehydration, and finally dry. This treatment method can improve the drying efficiency.

[0026] Furthermore, the softening method is: prepare a softener at a bath ratio of 1:20, and then soak the air layer blank after dyeing for 10-20 minutes, wherein the softener is composed of the following components in percentage by mass: 15-20% hydroxypropyl methylcellulose, 10-16% sodium stearate, 5-9% sodium lauryl sulfate, 8-11% alkylphenol polyoxyethylene ether, 16-21% sodium lauroyl sarcosinate, and the balance is amino silicone oil.

[0027] Description: Hydroxypropyl methylcellulose is a non-ionic semi-synthetic polymer. HPMC has good film-forming and thickening properties, which helps to improve the softness and smoothness of fabrics. Sodium stearate, as an emulsifier and saponifier, can fully mix the ingredients and improve the softening effect of fabrics. It also has a decontamination effect. Sodium dodecyl sulfate, as a surfactant, has good foaming and washing power. Sodium lauroyl sarcosine can improve the softness and gloss of fabrics. Amino silicone oil in the softener can penetrate into the fiber, provide lasting softness and smoothness, and prevent entanglement between fibers.

[0028] The beneficial effects of the present invention are:

[0029] The air layer fabric prepared by the present invention has an inner layer of a plain weft stitch structure that is not easy to rub against the body and improves comfort; the outer layer is wear-resistant and improves the texture of the fabric surface; the inner layer fabric is made of a mixture of cotton fiber and tencel fiber and has a strong sweat absorption effect; the outer layer fabric is a pearl mesh structure that increases air permeability and can make the moisture absorbed by the inner layer fabric evaporate quickly to achieve a quick-drying effect; the polyester fiber in the outer layer fabric has an anti-ultraviolet effect; and components that can improve the anti-ultraviolet effect of the fabric are also added to the dye, so that the air layer fabric of the present invention has the effects of quick drying and anti-ultraviolet.
