            Flame retardant fiber 
            
                    Flame retardant fiber includes two categories, 
            
The other is a high temperature resistant and refractory fiber, the melting point of this kind of fiber itself is very high, not easy combustion, this kind of fiber can also be used for special high temperature industrial nonwoven filter material, blanket and gaskets.  
            
Conventional synthetic fiber flame retardant 
            
One is through the regular chemical fiber (nylon, polyester, acrylic, polypropylene, etc.) add flame retardant dope, flame retardant can be based on copolymerization or blending with polymer fibers, resulting in permanent flame retardant fiber; 
            
By copolymerization flame retardant: after spinning and flame retardant monomer polymerization monomer copolymerization. Such as hurst TREVIRA type 271 of modified polyester fiber, Japan card card resistant nylon (CORDELON) modified whalen - d chlorofibre. The mainest is nitrile chlorofibre series products, it is of acrylonitrile and vinyl chloride vinylidene chloride or copolymer made by the wet or dry spinning fiber, in addition to the monomers such as acrylonitrile and vinyl chloride vinylidene chloride or, generally choose alkyl or alkenyl sulfonate as the third monomer, to improve the dyeing properties of the fiber.  
            
Blending method of flame retardant: through different polymer blending, mixed with a certain amount of flame retardant, the fiber has the flame retardant performance. Such as polyester or polypropylene fiber added with bromine, phosphide, can make flame retardant polyester fiber and polypropylene. The Finnish d silver (VISIL) flame retardant viscose fiber, containing silicate compound, the residue after burning, can still keep fibrous form. Our country has successfully trial-produced of flame retardant fiber flame retardant polyester, polypropylene, acrylic, whalen and viscose fiber, flame retardant polyester fiber and polypropylene fiber can be industrialized production.
