In this study, the effect of UV irradiation on mechanical properties of both natural and synthetic fabrics is investigated. Also the UV degradation of fabrics before and after TiO2 padding is studied. Cotton is used as natural fabric, and polyester, polypropylene, and polyamide were used as synthetic fabrics. After deposition with TiO2, prepared samples were irradiated by different dosage of UV light and the changes in fiber surface and the adhesion of nanoparticles is tested. The scanning electron microscopy, elemental analyses of Ti, and other methods were used. In some cases, the effect of stabilization of nanoparticles on fibers by UV light was realized. Reasons of this stabilization are the surface changes of polymer fibers-increase in surface roughness and oxidation of surface.
