1. Antistatic fabrics The methods for obtaining antistatic fabrics mainly include inlaid conductive fiber method and fabric surface finishing method. The method of embedding conductive fiber (co-woven with metal wire) can enhance the antistatic property of the fabric, and the effect is lasting, at the same time, it can also improve the moisture absorption and antifouling properties of the fabric; the fabric surface finishing method is carried out on synthetic fiber fabrics Antistatic resin finishing, these antistatic agents cover the surface of the fabric to increase the conductivity of the fiber through moisture absorption.
2. The development of waterproof and breathable fabrics mainly consists of three methods: high-density weaving, fabric coating and microporous film lamination. Among them, PTFE waterproof and moisture-permeable laminated composite processing is the most typical. Because the PTFE microporous film has a certain contact angle and micropore radius, it has a certain resistance to water pressure and moisture permeability. The laminated fabric produced by the biaxially stretched PTFE microporous film is waterproof and windproof. Sexual and moisture permeability.
3. Antibacterial and deodorant fabrics Antibacterial and health care fabrics can be produced by blending spinning and finishing methods. The blending spinning method is a method of adding antibacterial agents to the fiber at the polymerization stage, at the end of the polymerization or before the spinning nozzle and in the spinning dope; the finishing treatment method is to heat-set the antibacterial agent on the fiber, so as to achieve the purpose of antibacterial and deodorization .
4. Flame retardant textiles are made into blended fibers by copolymerizing flame retardant monomers with high polymers or adding flame retardants to polymers, and then woven into flame retardant fabrics; another method is to The flame retardant treats the fabric by spraying, padding or coating. When encountering fire, physical and chemical reactions occur to achieve flame retardant effect.
In addition, anti-shrinkage and anti-moth pretreatments can be used for dyeing and finishing. Various functional dyes such as light discoloration and far-infrared absorption can be used for dyeing. New dyeing and finishing technologies include biological enzyme technology, low temperature plasma technology, and microcapsules. Technology and other functional textiles. If the neutral or alkaline protease is used to prevent shrinkage of the wool fabric during the wet treatment process, the mothproofing agent and the wet treatment of the wool fabric such as washing, cooking and shrinking are carried out at the same time to achieve the effect of preventing moth ; Biological enzymes can remove impurities, fluff or reduce the amount of fibers on the fiber or fabric to improve the appearance and feel of the fabric; low temperature plasma technology can improve the shrinkage resistance of wool and the hydrophilicity and antistatic properties of polyester; Microcapsule technology is mainly used for various finishing operations such as printing, anti-wrinkle, anti-static, anti-water, anti-oil, and flame retardant.
