摘要
研究了紫外辐射对聚酯纤维的机械性能、表面形态结构的影响。结果表明,紫外辐射后的聚酯纤维强伸度大幅度下降,表面形态发生了很大的变化。本文通过研究聚酯纤维表面形态结构的变化来探讨聚酯纤维的断裂过程。
The UV-radiation behaviour of mechanical properties and surface morphology of poly (ethylene terephthalate) are studied. The results indicate that PET fibers are very susceptible to degradation, causing a large deterioration in stress and strain and surface morphology is modified to a great extent. Breaking process of PET fibers is discussed through analyzing changes of surface morphology of PET fibers in this paper.
