✦ Synopsis

Laser ablation of a poly(ethylene terephthalate) fabric with an excimer laser beam (248 nm) was analyzed by color tests, and the chemical structure change of the surface was studied. This analysis suggests the possibility of the formation of both OH and CHO groups on the poly(ethylene terephthalate) surface.
