Explanation

Special synthetic fiber that can not be ignited instantly in the flame. Its chemical structure has fused ring, three-dimensional crosslinking, metal chelation or can form a nonflammable surface carbonization layer or decompose nonflammable protective gas in the flame, and it releases very little smoke and harmful gas, and the fiber with the limiting oxygen index (LOI) greater than 32. antiflame fiber can generally maintain its original shape and good dimensional stability in the flame, and does not melt at high temperature. It has good textile performance and wearing comfort, but most of them have a certain color. For example, the phenolic fiber is golden yellow, the polyacrylonitrile pre oxidized wire is black, and the metal chelate can have white, red, blue and orange colors according to its different metals. It is mainly used to prepare special military uniforms Fireproof cord fabric and indoor decorations, blended clothing for patients, the elderly and children, thermal insulation materials, asbestos substitutes and various filter materials, and polyphenylaldehyde and polyacrylonitrile preoxidized fibers can be further processed into carbon fibers, activated carbon and ion exchange fiber.
