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.
