A flame-retardant polyester fiber obtained by spinning flame-retardant polyester and irradiating with ultraviolet light and having a limiting oxygen index value of greater than 30. Flame retardant 2-carboxyethylphenylphosphinic acid to improve the flame retardant properties of polyester, the use of polyester containing unsaturated double bond in UV irradiation, the double bond opens to form a crosslinking point, the formation of a certain amount of the network structure improves the heat-resistant temperature of the poly-fiber and improves the anti-dripping performance of the polyester fiber.
一种阻燃聚酯纤维,由阻燃聚酯纺丝后经紫外线照射而得,其极限氧指数大于30。阻燃剂 2-羧
乙基苯基
膦酸改善了聚酯的阻燃性能,利用聚酯中含有的不饱和双键在紫外线照射下,双键打开形成交联点,形成一定量的网状结构提高了聚酯纤维的耐热温度,改善了聚酯纤维的抗滴落性能。
