摘　　要：从加工和使用过程中纤维聚集态中分子链构象的有序化转变,研究聚对苯二甲酸丙二醇酯(PTT)纤维的弹性回复机理。研究了冷拉伸对聚酯纤维聚集态结构、聚酯纤维回弹性能的影响,并讨论了PTT纤维的弹性回复机理。The elasticity recovering mechanism of PTT fibers was studied through the ordering transformation of molecular chain conformation in aggregation of fibers in the course of processing and using. The effect of cold drawing on aggregation structure of PET fiber and the rebounding performance of PET fibers were studied, and the elasticity recovering mechanism of PTT fiber was discussed.
