Modification of the textile properties of polyester due to laser irradiation were studied and these properties included fibre weight and diameter, tensile strength and elongation, yarn abrasion, bending, surface lustre, wetting, air permeability as well as crystallinity. Properties such as wettability and air permeability were positively affected while properties of fibre weight and diameter, tensile strength, yarn abrasion and bending were adversely affected. In this study, laser irradiation used was not found to affect the bulk properties of polymer due to its low penetration depth, and hence, the effect of laser irradiation on bulk and structural properties was limited. However, the performance and comfort properties of the laser-irradiated polyester could be significantly affected by laser irradiation.
