The characteristics of polyester flame retardant non-woven fabrics, the main component of polyester flame retardant non-woven fabric is polyester, polyester fiber is chemical fiber, it is a polymerization product of terephthalic acid or diethyl terephthalate and ethylene glycol. Features are as follows : high strength, good elasticity, good heat resistance, smooth surface, good wear resistance, good light resistance, corrosion resistance, poor dyeability. Its flame retardant mechanism is mainly added flame retardant, flame retardant, is a kind Additives for materials, generally used in polyester plastics, textiles, etc., added to polyester to improve the fire safety of materials by improving the ignition point of materials or hindering the burning of materials, thereby improving the fire safety of materials. There are halogen flame retardants, organophosphorus and phosphorus-halogen flame retardants, intumescent flame retardants and inorganic flame retardants. The most used bromine flame retardants in halogen flame retardants. Polypropylene fiber is a synthetic fiber made from propylene. It features high strength, good wet strength and dry strength, abrasion resistance and corrosion resistance. Viscose fiber is a kind of regenerated cellulose fiber, which has good hygroscopicity, small breaking strength than cotton, environmental protection, non-toxic, and higher price than other fibers. The flame-retardant non-woven fabric can be divided into flame-retardant needle cotton and flame-retardant hot-air cotton according to the process. The flame-retardant needle cotton is entangled by the needle after the needle punching machine; the flame-retardant hot wind cotton is mainly formed by hot air blowing after laying the net. Both products have their own characteristics, the common features are fire retardant, light, warm, durable and environmentally friendly. Please indicate the source.
