Abstract

The invention relates to the technical field of textile auxiliary agents, and discloses a water-soluble thermal-reactive polyurethane hydrophilic, flame-retardant and antibacterial finishing agent. The water-soluble thermal-reactive polyurethane hydrophilic, flame-retardant and antibacterial finishing agent comprises components by following weight part: 15-20 parts of water-soluble thermal-reactive polyurethane, 0.1-10 parts of aceglutamide and 2-12 parts of glycerol. The aceglutamide is added as an additive in the finishing agent, and the water-soluble thermal-reactive polyurethane hydrophilic, flame-retardant and antibacterial finishing agent can catalyze proceeding of reaction and significantly improve crosslinking rate of the polyurethane and synthetic fibers, the lower concentration polyurethane can endow the synthetic fibers and wool fibers with lasting hydrophilicity, and simultaneously significantly enhances reactivity and softness, and is high in durability, and a fabric after being tidied not only has good hydrophilicity, but also has fire resistance and antibacterial performance.

Description

[0001] Technical field: [0002] The invention relates to the technical field of textile auxiliaries, in particular to a water-soluble heat-reactive polyurethane finishing agent. [0003] Background technique: [0004] Heat-responsive water-soluble polyurethane is a series of additives used in the textile finishing process that were successfully developed by Daiichi Kogyo Pharmaceutical Company of Japan and Bayer Company of Germany in the early 1970s after more than 10 years of research and development. Since this series of products does not contain formaldehyde, APEO, or solvent, it has been widely used in Western textile processing in Europe, America, and Japan since it was put into the market in the late 1980s. [0005] The main application of heat-responsive water-soluble polyurethane is anti-wrinkle and anti-shrinkage processing of wool and silk fabrics, anti-wrinkle and anti-shrinkage processing of cotton and linen fabrics, long-lasting water-absorbing and anti-static fin...
