| Abstract: | This study explores a new method to produce a cotton fabric with hydrophobicity, cross-linking, and photoactivity properties. Cotton fabric has been treated with nano titanium dioxide as a photo-catalyst and 1,2,3,4 butane tetra carboxylic acid as a friendly cross-linking agent in an ultrasonic bath. The photoactivity is tested by discoloration of the stained fabric with Direct Sky Blue 5B under UV-C (254 nm) irradiation. The treated fabric indicates a reasonable hydrophobicity along with photoactivity and cross-linking. The results indicate that the color variation under UV irradiation is higher for the cotton fabric treated with TiO2. However, the photoactivity of the treated fabric decreases after repeated laundering. Moreover, the creasing properties of the nano TiO2 treated cotton fabrics decrease considerably. The SEM images show a TiO2 layer on the cotton fibres. The experimental data processing has been carried out by response surface methodology based on central composite design introducing three optimized models. |
