METHOD FOR TREATING POLYESTER

摘要

PURPOSE:To obtain a polyester material having a surface excellent in ultraviolet ray absorptivity by irradiating the polyester material with ultraviolet ray pulsed laser beams. CONSTITUTION:The objective method for treating a polyester is characterized by irradiating the polyester with 10-50 pulses of ultraviolet ray pulsed laser beams having 248nm wavelength under conditions of pulse energy (30-80mJ/cm<2>/ pulse fluence).
