Abstract:

Based on the hydrophilic modified principles and associated problems of polyester fiber, and combined with current commonly used hydrophilic modification methods, several areas of hydrophilic modification for polyester fiber surface were introduced: mainly included morphological structure modification on surface, grafting modification on surface, and finishing treatment with hydrophilic finishing agent. The modification of surface grafting is introduced emphatically, especially irradiated graft modification, and the mechanism of irradiation induced grafting is analyzed, and the measurements for improving the grafting yield of polyester are discussed. Base on the advantages and disadvantages of these methods, it points that the problems of hydrophilic modification for polyester fiber surface at present and the development orientation in the future, considering that ideal method of hydrophilic modified for polyester fiber should be without decreasing its original excellent performance, good durability, high economic efficiency, environment-friendly, and so on.

Key words: polyester fiber, irradiation, grafting, hydrophilic modification, surface modification
