Problems solved by technology

People's research on the modification of polyester fiber has never stopped, especially the research on flame-retardant polyester fiber. The polyester fiber before modification is easy to melt and decompose when heated, and it will melt and drip when burned. The key to polyester fiber lies in the use of flame retardants, and the key technical solutions for improving the flame retardant properties of most flame retardant polyester fibers with good performance are still kept secret. At present, the flame retardant modification methods of polyester fibers mainly include copolymerization Flame retardant modification, blending flame retardant modification, grafting flame retardant modification and post-finishing flame retardant modification, copolymerization flame retardant modification means adding flame retardants and other additives during the polymerization of polyester fibers to achieve Flame retardant effect, but this method is prone to side reactions, and has high requirements for the stability of flame retardants; blending flame retardant modification, that is, adding flame retardant additives to the spinning melt; grafting flame retardant modification The permanent process is more complicated, not easy to master, and the research and development period is long, and the investment is relatively large; after flame-retardant finishing, the polyester fiber is impregnated with a finishing agent to endow it with flame-retardant properties. The disadvantage is that many flame-retardant polyester fibers after finishing, Its flame retardant properties will gradually weaken with the number of washes and use time
[0003] Many traditional mattresses use sponge as a filling, because the sponge is soft and comfortable, and has good warmth retention. However, the flame retardancy of the sponge is poor, and the burning speed is extremely fast, and the cost of flame-retardant cotton is relatively high.
At present, polyester fiber is widely used in clothing fillings and other fields, and it is also widely used in the field of mattresses. When it is used as mattress filling, it not only needs to have the comfort and warmth of sponge, but also needs to have good flame retardancy. , but at present, most polyester fiber mattresses have poor flame retardancy and some do not even have flame retardancy. Polyester fiber mattresses are easy to breed bacteria and mildew in humid environments, and some even have mildew spots on the bottom. Therefore, the research on flame-retardant and antibacterial polyester fibers for mattresses is of great significance
