【Abstract】 In order to improve the dye up-take of fine-PET,this study uses low-temp.oxygen plasma to modify the fine-PET.The law of effects of plasma treatment time.gas pressure,discharge power on fine-PET’s properties was discussed.The results show that the dye up-take increased by 17% under the best technological condition,so the pollutant discharge quantity can be decreased greatly and it is a clean-process beneficial to environment protection.The aging effect experiment illustrated that the wettability of fine-PET did not decrease with the passage of tinm.更多还原
