摘　　要：通过对聚对苯二甲酸乙二醇酯/聚对苯二甲酸丙二醇酯(PET/PTT)和聚对苯二甲酸乙二醇酯/聚对苯二甲酸丁二醇酯(PET/PBT)2种复合纤维的热收缩率、卷曲收缩率、卷曲模量、卷曲稳定度、断裂强度以及上染率等的测试,对比研究了2种复合纤维的热收缩性能、卷曲性能、力学性能和染色性能。结果表明,无论是干热处理还是沸水处理,PET/PTT的收缩率、卷曲性能、断裂强度均高于PET/PBT,2种复合纤维的断裂伸长率相差不大,但PET/PTT的上染率要低于PET/PBT。The property of thermal shrinkage,crimp,mechanical and dyeing for the two kinds of component filaments PET/PTT and PET/PBT were studied.The results showed that the shrinkage rate,the crimp property and breaking strength of PET/PTT were higher than that of PET/PBT.But the breaking elongation of two kinds of component filaments were closed,and the dye uptake of PET/PTT was lower than that of PET/PBT.

关 键 词：PET/PTT PET/PBT 复合纤维 卷曲性能 力学性能
