In order to study the self-cleaning property of fabric finished by nano-TiO_2 particles, polyester fabric was finished with self-made broad spectrum corresponding-based nano TiO_2 hydrosol(abbr. TiO_2 sol) by high temperature pressure exhaustion process. Organic dye Rh B was selected as special model stain to evaluate the effect of TiO_2 sol dosage and Rh B concentration on self-cleaning performance of the finished fabric, which was compared with the fabric finished by padding process. The results indicated...
