Problems solved by technology

After the 1960s, with the formulation of fire protection regulations in many countries, flame retardant technology has been widely used in textiles, but it mainly involves the surface flame retardant treatment of fabrics or the use of halogen and phosphorus organic compound flame retardants, such as Lenging ( Austria), Polynosic (Japan) HFG (Japan), these fibers containing organic compound flame retardants, although the flame retardant effect is good, but they are not friendly to the environment or will release a lot of poisonous gas and smoke when burning, which has safety

Abstract

The invention discloses environment-friendly high-temperature-resistant durable flame retardant fibers and a preparation method of the environment-friendly high-temperature-resistant durable flame retardant fibers. The environment-friendly high-temperature-resistant durable flame retardant fibers comprise the following raw materials: cellulose, a flame retardant and a cationic crosslinking agent, wherein the flame retardant is a carbon-nitrogen flame retardant which meets relevant national requirements in environment-friendliness and flame retardance. By adopting the preparation method disclosed by the invention, spinning pause easily caused by aged and gelatinized glue of previous silicon flame retardant, downstream spinning and spinning difficulty caused by low strength and loss of the flame retardant components as well as a lasting flame retardant effect in the using process are overcome. Long and short filaments produced by the process can be used for manufacturing clothes, as well as knitwear and textiles for home furnishing, army protection and public decoration.

Description

technical field [0001] The invention belongs to the field of chemical fiber processing, and in particular relates to an environment-friendly high-temperature-resistant durable flame-retardant fiber and a preparation method thereof. Background technique [0002] Flame retardant science and technology is a science developed by human beings in order to meet the needs of social development, prevent and control fires, and protect the safety of human life and property. scientific method. Flame retardant technology converts combustible materials into flame-retardant or non-combustible materials according to the combustion characteristics of combustible materials, reduces the burning speed of substances, and prevents fire from expanding. [0003] With the development of social material civilization, people pay more and more attention to flame retardant technology. As early as 1785, the British used a mixture of alum, borax and ferrous sulfate to make cellulose textiles and pulp fla...
