摘要
为减少聚对苯二甲酸乙二醇酯(PET)在燃烧过程中产生的熔滴造成的危害,以六氯环三磷腈和对羟基苯甲醛为原料合成阻燃剂 HBCP,并将其与 PET 共混后经熔融纺丝制得阻燃抗熔滴PET纤维.探究了 3 种分散染料(分散黄 3G、分散蓝 2BLN、分散红 3B)对纯PET纤维与阻燃抗熔滴PET纤维的上染工艺,包括染料质量分数、染色温度、上染时间以及 pH 值对纤维染色性能的影响.试验结果表明:分散黄 3G与分散红 3B均在染料质量分数为 1.0%、上染温度为 130℃、染色时间为 60 min、染液 pH 值为 5 时上染率最高,染色效果较好;分散蓝 2 BLN 在染料质量分数为2.0%、上染温度为 120℃、染色时间为 60 min、染液 pH 值为 5 的条件下达到最高上染率;在相同染色工艺条件下,相比纯PET纤维,阻燃抗熔滴PET纤维对 3 种分散染料的上染率都有一定程度的提高.
Abstract
In order to reduce the hazards caused by molten drops of PET during combustion,a flame retardant HBCP was synthesized from hexachlorocyclotriphosphazene nitrile and p-hydroxybenzaldehyde,and HBCP was blended with PET and then melt spun to produce flame retardant anti-dripping PET fibers.The effects of three disperse dyes(disperse yellow 3 G,disperse blue 2 BLN and disperse red 3 B)on the dyeing process of pure PET fibers and flame flame-retardant and anti-dripping PET fibers were investigated,including the effects of dyeing mass fraction,dyeing temperature,dyeing time and pH value on the dyeing performance of the fiber.The experimental results show that the dyeing rate of both disperse yellow 3 G and disperse red 3 B is the highest and the dyeing effect is better when the dye mass fraction is 1.0%,dyeing temperature is 130℃,dyeing time is 60 min,and the pH value of dye solution is 5;the disperse blue 2 BLN achieves the highest dyeing effect when the dye mass fraction is 2.0%,the dyeing temperature is 120℃,the dyeing time is 60 min,and the pH value of dye solution is 5.Under the same dyeing process conditions,the dyeing rate of all three disperse dyes is improved to some extent for the flame-retardant and anti-dripping PET fibers compared to the pure PET fibers.
