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2BLN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。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 which were HBCP was blended with PET and then melt spun to produce flame retardant anti-molten droplet dripping PET fibers.The effects of three disperse dyes(disperse yellow 3G,disperse blue 2BLN and disperse red 3B)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 3G and disperse red 3B is the highest and the dyeing effect is better when the dye mass fraction is 1.0%,the dyeing temperature is 130℃,the dyeing time is 60 min,and the pH value of the dye solution is 5;the disperse blue 2BLN 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 the 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.
