Description

technical field [0001] The invention relates to a product in the technical field of textile fibers and a preparation method thereof, in particular to an anion flame-retardant and antibacterial fiber and a preparation method thereof. Background technique [0002] With the development of the national economy and the improvement of people's living standards, the application fields of various fibers and textiles are gradually expanding. Flame retardant Because most of the textiles are flammable, they are more and more fire hazards. Therefore, people pay more attention to the development and application of flame retardant fibers and textiles than before. [0003] The development of antibacterial materials started in the 1970s. It can inhibit the growth and reproduction of microorganisms on the fibers, thereby not only protecting the fibers from the invasion of microorganisms, preventing their discoloration and mildew, but also protecting the wearer and users. Others, including p...
