The flame-retardant varieties of polyester and viscose two major chemical fibers entered the 2014/2015 China Fiber Trend Report, reflecting from the side that the flame-retardant problem of textiles has received high attention from all walks of life.

   Textiles made of polyester and viscose fibers can be seen everywhere in life, and their flame-retardant varieties become popular, which will play a major role in promoting the application of flame-retardant textiles in my country. Moreover, with the continuous development of society, this trend will become more and more obvious.

In the 1950s, my country began research on flame retardant technology, developed flame retardants in the 1970s, began to study flame retardant technologies for synthetic fibers and blended fabrics, and developed flame retardants and finishing for cotton, polyester and blended fabrics in the 1980s. Technical and flame retardant synthetic fibers. At present, the intrinsic flame retardant has been praised by the industry.

   The flame-retardant fiber released by China Fiber Trends 2014/2015 mainly recommends viscose flame-retardant fiber and polyester flame-retardant fiber, which indicates that the technologies of these two fibers have been relatively mature and are recognized by the market.

   It is not too late to study viscose flame-retardant fiber in China, and there was a climax of research and development of flame-retardant viscose fiber around 1990. Research and development institutions and enterprises have explored the application of blending and dipping methods in the flame retardant modification of viscose fibers.

The organic compounds or inorganic substances containing phosphorus and halogen in the flame retardant for flame retardant viscose fibers will pollute the environment. Therefore, non-toxic or low-toxicity, less pollution, environmentally friendly inorganic flame retardants and nano-inorganic flame retardants are The development direction of flame retardant viscose fiber. At present, the viscose flame-retardant fiber uses pre-spinning injection technology and a special viscose production process to overcome the problem of dispersion of inorganic particles in the original solution, and prepare viscose staple fiber with high efficiency and flame retardancy. Inorganic viscose flame-retardant fibers have become environmentally friendly fiber materials, mainly represented by cotton-type, medium-length, and wool-type flame-retardant fibers. The Baishan brand flame-retardant viscose fiber produced by Jilin Chemical Fiber has good permanent flame-retardant properties, and washing and friction will not affect the flame-retardant properties. Not only is the viscose itself made of regenerated natural plants as raw materials, the waste can be degraded naturally and meets environmental protection requirements, and its phosphorus-based flame retardant also meets the EU's flame retardant and halogen-free requirements. The technological breakthrough has opened a window for the promotion of my country's flame-retardant viscose fiber worldwide.

   polyester flame retardant fiber adopts advanced copolymerization reaction type flame retardant modification method, and the flame retardant is directly embedded in the polyester molecular chain to spin a polyester product with permanent flame retardant effect. The product uses phosphorous flame retardants, which can reduce toxicity and smoke generation. In addition to the copolymerization method, some companies can also use the masterbatch method to improve the uniformity of the flame retardant dispersion. At the same time, colorants, antibacterial agents, etc. can be added to the masterbatch to prepare functional flame-retardant masterbatch, combined with profile spinning technology, to prepare functional flame-retardant fibers.
