With the improvement of living standards, people's functional requirements for textiles have increased from simple warmth to a variety of special functions. In recent years, the rapid development of durable flame retardant finishing, moisture wicking finishing, waterproof and breathable finishing, anti-mosquito finishing of shirts and mosquito nets, anti-ultraviolet finishing of summer clothes, far-infrared thermal finishing of winter clothes, health care skin care and hygiene finishing of underwear, and home textiles Product antifouling, easy decontamination finishing and so on. Due to the high degree of crystallinity and orientation of polyester macromolecules, it is usually difficult for the finishing agent macromolecules to enter the fiber. In the past, overflow dyeing machines were mostly used for finishing and dyeing together in batch production, which not only had low labor efficiency, but also had large equipment limitations and difficult process control. To this end, after repeated trials, an auxiliary agent TX-ZR001 that can be used directly in finishing was developed, which can effectively introduce macromolecules of the flame retardant finishing agent into the polyester fiber in the finishing process.
