Abstract

The invention discloses a flame-retardant polyamide fiber. The flame-retardant polyamide fiber is prepared mainly by the following ingredients in parts by weight: 50 parts of polyamide fibers, 10 to 20 parts of epoxy resin, 5 to 15 parts of formaldehyde resin, 1 to 9 parts of tetrakisphosphonium chloride, 1 to 7 parts of pentaerythritol, 2 to 8 parts of ammonium dihydrogen phosphate, 5 to 15 parts of decabromodiphenyl ether, 0.1 to 0.9 part of antimonous oxide, and 0.5 to 1.5 parts of nano silicon dioxide. Compared with the prior art, the flame-retardant polyamide fiber is simple in process and low in cost, not only has the advantages of the polyamide fiber in the prior art, but also can remarkably improve the flame-retardant performance of the polyamide fiber and is excellent in overall performance.

Description

Technical field [0001] The invention involves a flame retardant polyamide fiber, which is a technology field in printing and dyeing materials. Background technique [0002] my country is in the stage of economic steaming, and it is also a period of fire accidents. Fires caused by textiles are often reported.Polyamide fiber is the earliest synthetic fiber in the world to achieve industrialized production.In the early 1990s, the yield of polyamide fibers in the world accounted for 24%of the total synthetic fiber yield, ranking second.Although it is not a flammable fiber (the extreme oxygen index LOI = 22 ~ 24), the existence of melting drops when it is burned is very easy to spread to the fire, which is very unfavorable to fire disaster relief.The golden stage of my country's fabric flame retardant research began in the early 1980s, about 30 years later than European and American countries.The flame retardant fibers and fabrics in Europe and the United States were commodized in the...
