Knock on the door of flame retardant fabric and flame retardant fiber

Classification:
flame retardant fabric

While people consume fiber products in large quantities and enjoy the warmth, comfort and beauty they bring to people, fires caused by the burning of fiber products have also become one of the major disasters in modern society. Investigations into fatalities caused by fires show that fires caused by interior decorations and textiles account for the largest share of the total number of fires. At the same time, we found that the harmful gases released when flammable textiles burn are much more harmful to the human body than flame-retardant textiles. Therefore, in order to prevent fires, the production ofFlame-retardantfibers has received increasing attention.

Abroad, in response to the huge threat to people’s life safety caused by the continuous fires in the United States, the U.S. Federal Safety Commission formulated the 1633 Act with more stringent requirements based on the original California TB603 standard, and in July 2007 It will be enforced in all 50 states in the United States on the 1st. The bill mainly targets theflame retardant performance of mattress products.
Selected silicone flame retardant viscose fiber

Early flame-retardant viscose fibers were produced by post-finishing methods. It is to treat the fiber with nitrogen-containing organic phosphate compounds after the fiber is made or during the production process, or to coat the surface of the fiber with antimony trioxide and halogen-containing flame retardant in a latex state. The fiber prepared by this method has better flame retardant effect, but the smoke generated by fire is large, the fiber has poor water resistance, and the flame retardant property is easily damaged during the dyeing and finishing process of the fiber.

Later, people developed a blending addition method to produce flame-retardant fibers. It adds flame retardants to the spinning solution at the later stage of the dissolution of cellulose sulfonate to produce flame-retardant viscose fibers. When using this method, in order to meet the flame retardant requirements, a large amount of flame retardant needs to be added to the viscose solution. The weight of the added flame retardant is usually 15% to 30% of the fiber weight. Since the flame retardant is added to the viscose solution before spinning, this requires the flame retardant to not only have excellent alkali resistance, acid resistance, and heat resistance, but also be insoluble in water.
