Abstract: Nano-titanium dioxide finishing agents were prepared by sol-gel method and used for multi-functional treatment of cotton fabrics by dip-padding technique.The results show that fabrics treated with the finishing agent had excellent UV resistance,increased UPF,and good soaping fastness.In addition,it had good anti-bacterial property with bacterial inactivation rate over 80%.It was observed that the fabric texture and TiO₂ concentration had an impact on the result of the finishing,higher the TiO₂ concentration and denser the fabric texture,better the UV resistance and anti-bacterial property.
