Functionalization of a Cotton Fabric Surface with Titania Nanosols: Applications for Self-Cleaning and UV-Protection Properties

In this study. cotton fabric was successfully modified by titania nanosols prepared by means of the sol-gel process with tetrabutyl orthotitanate [Ti(OC(4)H(9))(4)] as the active ingredient. The cotton fabric was padded with the nanosol solution. dried at 60 degrees C, and cured at 150 degrees C Scanning electron microscopy showed the presence of a titania film on the fiber surface The photocatalytic properties of titania-nanosol-treated Cotton fabric were investigated The results showed that stains of coffee and red wine were successfully decomposed by exposure of the stained fabric to UV radiation Furthermore, titania-nanosol treatment imparted to the cotton fabric a very good protection against UV radiation The durability of the treatment was investigated by performing repeated home laundering, and the results showed no effect of laundering on the UV-protection efficiency
