摘要: 研究了紫外线辐射对聚酯纤维的影响以及消光剂、纳米紫外线屏蔽剂的稳定作用。研究结果表明,紫外线辐射后聚酯纤维样品的分子量、强伸度大幅度下降,结晶度有所提高,玻璃化温度、熔点均有所降低。消光剂、纳米级紫外线屏蔽剂对辐射过程中的聚酯纤维样品起到了稳定作用。

Abstract: The effect of UV-radiation on PET and the stabilizing role of dulling agents and UV shield agents were investigated.The results indicated that PET fibers after exposure to UV-radiation exhibited a marked reduction in molecular weight and tensile strength,noticeable decline in glass-transition temperature and melting temperature,but an increase in crystallinity.And dulling agents and the UV shield agent had stabilizing function for PET during exposure to UV-radiation.
