摘要
研究了多功能共聚酯与聚对苯二甲酸乙二酯（PET）纤维的力学性质。结果表明,多功能共聚酯纤维的回弹性及尺寸稳定性均好于PET纤维,而在相同的定伸长下,多功能共聚酯纤维的内应力比PET纤维高,并且其内应力松弛过程与PET纤维相似。
In this paper, the mechanical properties of the fibers made from multifunctional copolyester and PET have been investigated. The results showed that the rebound resilience and the dimensional stability of the copolyester fiber were better than that of PET, under the constant elongation, the internal stress of the copolyester fiber was higher than that of PET, and the relaxation process of the internal stress about the copolyester fiber bore analogy to that of PET.
