Types And Standards Of Flame Retardant Non Woven Fabric

    Polyester flame-Retardant Non-woven fabric is mainly composed of polyester, polyester fiber belongs to chemical fiber, is terephthalic acid or terephthalic acid diethyl ester and ethylene glycol polymerization products. Features are as follows: High strength, good elasticity, good heat resistance, smooth surface, good wear resistance, good light resistance, corrosion resistance and poor dyeing. Its flame-retardant mechanism is mainly to add flame retardants, flame retardants, is a kind of material additives, generally used in polyester plastic, textiles, etc., added to the polyester through the improvement of material ignition or blocking material combustion to achieve flame-retardant purposes, thereby improving the fire safety of materials.Flame Retardant Non Woven Fabric
   Category: Flame retardants are divided into many kinds, there are halogen flame retardants, organic phosphorus and phosphorus-halogen flame retardants, intumescent flame retardants and inorganic flame retardants. At present, the most used is halogen flame retardants in the brominated flame retardants. Polypropylene fiber is the synthetic fiber made from propylene, characterized by high strength, wet strength, good dry strength, abrasion resistance and corrosion resistance. Viscose Rayon belongs to regenerated cellulose fiber, has good hygroscopicity, the fracture strength is smaller than cotton, environmental protection, non-toxic, the price is higher than other fiber. Flame-Retardant Non-woven fabric According to the process can be divided into flame-retardant needle cotton and flame-retardant hot-air cotton. Flame-retardant needle cotton is a tangled fiber after puncture by needle-punched machine. Both products have their own characteristics, common is flame-retardant fire, light, warm, durable, environmental protection.Flame Retardant Non Woven Fabric
   Test standards include American CFR1633, British BS5852 and American TB117 standards.Can pass the American CFR1633 test product characteristic: flame retardant, resist melting, a small amount of smoke, do not release poisonous gas, have self extinguish effect, after carbonization can maintain original condition, moisture absorption, breathable, feel soft, elastic lasting, mainly adapt to export American high-grade mattress.Flame Retardant Non Woven Fabric
   Through the BS5852 test standard product Characteristics: The current European market on soft furniture mattress and seat category of mandatory flame-retardant requirements, at the same time, soft and hard to adjust, good fire performance, 30 seconds automatically extinguished, mainly applicable to export Europe market, high-end sofa used more. Can pass the American TB117 test product characteristic, to the fire protection request is relatively low between three, the longest burning time does not surpass 8 seconds, applies to the textile, the furniture which exports to the United States.Flame Retardant Non Woven Fabric
