Abstract
UV-laser induced changes on surface structure and properties of Poly(ethylene terephthalate) (PET) fabric were discussed. Scanning electron microscope (SEM) observation revealed the morphological modification of PET fabrics with the ablation of 308nm excimer laser. The contact angle measurement and vertical drop test were used to find out the difference in the wetting property of the untreated and laser ablated PET fabric. Extra carboxylic radicals and increased amorphous part on the surface of the laser-ablated fabric were estimated by the attenuated total reflectance Fourier-transform infrared spectrum (ATR FT-IR) analysis. Dyeing property of the PET fabric was changed evidently by laser irradiation.
