Polyester surfaces were modified by a KrF excimer laser irradiation and those rough surfaces could be observed with SEM pictures. Comparing with 50mJ/cm² and 200mJ/cm² pulse energy, the SEM images became sharper and clearer with an increase in the pulse energy and the frequency of radiation. A microscopic change of surface structures by plasma irradiation could be observed with AFM pictures but modification by electron beam irradiation could not. Through the process of polyester fabric transfer printing, a study was made of the effect of surface modification. After laser, plasma, and electron beam treatment, there was found to be an increased darkening of the fabric color. In addition, there was a remarkable improvement in the wettability of polyester fabrics though O₂ plasma and electron beam irradiation.
