摘要(Abstract)：
本文通过研究纺丝、拉伸工艺条件变化对涤纶沸水收缩率的影响,结合对纤维结晶变化的研究,探讨了影响收缩率的主要因素,并从纤维结构的角度,作了机理上的讨论.其结论对“异收缩”纤维加工工艺具有一定的意义.
In this paper, the relationship between the production conditions and the shrinkage in boiling water of PET fiber are investigated. Compared with the change of crystallinity of the sample fiber, the effect factors on shrinkage in boiling water and the mechanism were discussed. The results were useful for the production of differential shrinkage PETyarn.
