Dyeing And Finishing Technology Of Functional Textiles

　　 Antistatic fabric 。 The main methods for obtaining antistatic fabrics are embedded conductive fiber method and fabric surface finishing method. The method of embedding conductive conductive fibers (woven together with metal wires) can enhance the antistatic property and durable effect of fabrics, as well as improve the hygroscopicity and antifouling properties of fabrics. The surface finishing method of fabrics is antistatic finishing of synthetic fabrics, these antistatic agents cover the surface of fabrics, and enhance the electrical conductivity of fibers through moisture absorption.

Waterproof and moisture permeable fabric. The development of waterproof and moisture permeable fabric is mainly composed of 3 methods: high density weaving, fabric coating and microporous membrane laminating. Because PTFE microporous membrane has certain contact angle and micro pore radius, it has certain water resistance and moisture permeability. The laminated fabric produced by biaxially oriented polytetrafluoroethylene microporous membrane has the functions of water repellency, wind protection and moisture permeability.

Antibacterial and deodorant fabric. Antibacterial health care fabric It can be produced by Blending Spinning and finishing. The common blended yarn method is to add antibacterial agents into the fibers at the polymerization stage, the end of polymerization or before the spinning spout and the spinning raw fluid. The finishing method is to heat the antibacterial agent on the fiber. If the steamed polyurethane knitted fabric is steamed in the cylinder steamer, the middle and the longitudinal stretching of the hot and humid steamed fabric will be stretched and dragged to the bottom of the box. When the long ring steaming machine is steamed, it is also necessary to note that the cloth tension is small, so long as the cloth can be driven into the steaming machine. So as to achieve the purpose of antibacterial and deodorant.

Flame retardant textiles. The flame retardant monomers are copolymerized with polymers or mixed with flame retardants in the polymer to be mixed and made into blends and then woven into flame retardant fabrics. The other is to treat the flame retardant with spray, dip, or coating. The setting temperature is 135~160 degrees, because the finished product is stabilized on the basis of predetermined shape. Too high setting temperature will not only make the fabric yellowed or make some softening agents yellowed, but also make the spandex lose some elasticity and produce bad effect. When the fire occurs, physical and chemical reactions occur, so as to achieve the effect of flame retardancy.

In addition, Dyeing and finishing technology It can be used for shrinkproof, moth proofing, dyeing with various functional dyes, such as photochromism and far-infrared absorption. New technologies of dyeing and finishing, including enzyme technology, low temperature plasma technology and microcapsule technology, are used to develop functional textiles. If neutral or alkaline protease is used to prevent shrinkage of wool fabrics during wet processing, the moth proofing agent can be carried out at the same time as wet treatment of woollen fabrics such as washing, boiling and shrinking, so as to achieve the effect of moth proofing and shrinkproof. Biological enzymes can remove impurities, fuzz or fabric from fabric or fabric, so as to improve the appearance and feel of the fabric; low temperature plasma technology can improve the Shrinkproof property of wool and the hydrophilicity and antistatic property of polyester, etc.
