Abstract Optimization of cured cotton textiles through self-cleaning property constructs the main goal of present investigation. Cotton textiles with 0.1, 0.3, 0.5, 1 and 1.5 wt% were cured by Nano-titanium dioxide (P25 Degussa) with and without using cross-link method. Stability of the TiO2 coatings is a particular requirement for textiles because they are subject to frequent washing hence use of a suitable coating condition is necessary. During this study sucsinic acid was used as spacers to attach TiO2 to cotton. Viscosity degree of titania particles to cotton fabrics is studied by burning method by determining the percentage of titania coated. Further, following experiments were conducted: thermal behaviour of curing samples with TGA, self-cleaning degree of curing cotton fabrics and stained samples with Dark green BN green 6 and Reactive orange V-2G dyes under irradiation of 20 & 400 W UV lamps using reflectance spectrophotometer, structure and morphology of titania coated cotton fabric through scanning electron microscopy (SEM) and crystallinity of titania coatings by X-ray diffraction (XRD). Tearing strength of cured cotton fabrics was investigated before and after employing irradiation process. Results show that stability of Nano TiO2 coating and degree of self-cleaning cured with cross-link method is extremely higher than in non cross-link operation and cotton cellulosic chains are not decomposed by photocatalytic activity of titania.
