Description

A kind of sportswear fabric and sportswear with antibacterial, deodorant and moisture absorption effects

technical field

The invention relates to the technical field of textile fabrics, in particular to a sportswear fabric and sportswear with antibacterial, deodorizing and hygroscopic effects.

Background technique

As one of the three elements of clothing, fabrics can not only interpret the style and characteristics of clothing, but also directly affect the color and shape of clothing. Some fabrics can be used to make sportswear, and sportswear refers to clothing specially used for sports competitions. clothing. In a broad sense, it also includes clothing worn in outdoor sports activities. Therefore, sports fabrics have certain requirements for antibacterial, deodorant and moisture absorption effects.

Bamboo fiber is a fiber extracted directly from bamboo by mechanical and physical methods. Compared with the bamboo pulp fiber prepared by chemical method, it is a kind of natural and environment-friendly green fiber in the true sense, and the wearing comfort of bamboo raw fiber is also better than that of bamboo pulp fiber. Bamboo fiber not only has good air permeability, instant water absorption, strong wear resistance and good dyeability, but also has natural antibacterial, antibacterial, mite removal, deodorant and anti-ultraviolet functions. Meet the requirements of green, environmental protection, health and comfort. Compared with cotton fiber, bamboo fiber is thicker, harder, more rigid, has strong hygroscopicity during weaving, and has poor fabric shrinkage, hand feeling and drapability, which limits its application in sportswear fabrics and cannot fully realize its commercial value. The development and application of its high added value in the textile industry.

For example, Chinese patent CN108166070A discloses a short bamboo fiber and its preparation method, which belongs to the field of plant fiber production technology, including bamboo slicing, softening treatment, tearing treatment, enzyme treatment, chemical treatment, disc grinding treatment, pre-dehydration, and drying. In order to solve the problems of low yield, heavy pollution and high cost of the existing preparation method, the present invention mainly replaces the traditional multi-roller rolling with a screw extrusion tearing machine, and puts biological treatment before chemical treatment to reduce chemical Types and biological enzymes are achieved by replacing steam drying, fiber opening and multi-stage carding with disc grinding and impinging flow drying. The beneficial effect of the invention is that the yield of short bamboo raw fibers is high, the cost is low, and the pollution in the preparation process is light. But this invention is after compound enzyme treatment, carries out chemical treatment again, and chemical treatment carries out dehydration drying and makes bamboo fiber, and the chemical alkalinity used during chemical treatment is stronger, and environment can be polluted to a certain degree, and also It will damage the bamboo fiber to a certain extent, and will also have a certain impact on the deodorization and moisture absorption effect of the subsequent fabrics.

Contents of the invention

The present invention provides a sportswear fabric and sportswear with antibacterial, deodorizing and hygroscopic effects to solve the deficiencies in the prior art mentioned in the background art above.

In order to solve the problems of the technologies described above, the technical solution of the present invention is:

Wherein, in step (3), the consumption of pectinase is 10-20IU/Kg absolute dry fiber, the weight of adding pectinase solution is 6-10 times of filament weight, the treatment condition of pectinase: temperature is 50-70°C, pH value 6-8, treatment time 60-120 minutes.

Wherein, in step (3), the dosage of xylanase is 5-10IU/Kg dry fiber, the weight of adding pectinase solution is 6-10 times of filament weight, the treatment condition of pectinase: temperature The temperature is 40-60°C, the pH value is 7-8, and the treatment time is 50-80 minutes;

Wherein, in step (4), by mass percentage, the chemical treatment solution contains 3%-4% soda ash, 0.1%-0.3% sodium silicate, 0.5%-2% sodium sulfide and 1%-2% of urea.

Wherein, in step (5), the consumption of cellulase is 2-8IU/Kg absolute dry fiber, the weight of adding pectinase solution is 6-10 times of filament weight, the treatment condition of pectinase: temperature is 60-80°C, pH value 4-5, treatment time 40-80 minutes.

Wherein, in the process of debonding treatment in step (6), Span 80 or Tween 80 is applied, and the applied amount is 0.5-1.5% of the mass of the bamboo fiber. When combing, the fiber is easy to be broken. Applying a certain amount of Tween 80 and Span 80 can increase the strength and softness of the fiber.

After adopting the above technical solution, the present invention has the following advantages compared with the prior art:

In the preparation process of the bamboo fiber in the present invention, xylanase is first used to remove the hemicellulose in the fiber, and then pectinase is used for enzymolysis to remove the pectin in the inner layer of the fiber, and then added Chemical treatment is carried out in a mixed solution of soda ash, sodium silicate, sodium sulfide and urea with low alkalinity. Chemical treatment mainly causes swelling to occur inside the cellulose, weakens the hydrogen bond between molecules, improves the softness of the fiber, and also increases the crimp, elasticity and cohesion of the fiber, increases the elongation at break, and reduces the initial The modulus improves the flexibility of the dyeing performance of the fiber and improves the wearing performance of the fabric. After chemical treatment, it is added to cellulase solution for enzymatic hydrolysis to destroy the surface of the fiber, reduce the adhesion between fibers, and destroy the internal structure of the fiber, split the fiber bundle, and increase the weight loss rate of the fiber.

In the invention, the hemicellulose and pectin in the fiber are removed by enzymatic hydrolysis before the chemical treatment, so that the subsequent chemical treatment is relatively easy, so the chemical treatment solution is less alkaline and used in less amount. After chemical treatment, cellulase is used for enzymatic hydrolysis to make the fiber itself soft, reduce the fiber stiffness, and increase the joint strength, making the bamboo fiber more suitable for sports fabrics.

The bamboo fiber in the sports fabric of the present invention has natural antibacterial and antibacterial effects, and has good air permeability and instant water absorption. At the same time, the mixing of polyester fiber and spandex fiber makes the fabric maintain a certain degree of elasticity, which is in line with the sterilization of sports fabrics , Moisture absorption and deodorization requirements.
