Abstract:

 In order to reduce the suit fabric washing times and energy consumption with remaining fabics apppearance and style in the maximum degree, the photocatalyzed self -cleaning property of the nano TiO2 powder was studied. Based on the single factor method combined with orthogonal experimental method, this paper effectively disperses the composite powder , and a kind of compound nanometer finishing agent was exploited and developed too .Wool-polyester blended suit fabric was used as the main reseach object. The experimental results showed that the wool-polyester blended suit fabric had better photocatalytic self-cleaning properties with nano-self-cleaning finishing agents. The suit fabric showed the best self-cleaning effect with the amount of 10% nano finishing agents , and grease stain will break down a lot within 60h . Repeatability was tested after the suit fabrics was treated with nano self-cleaning finishing agents, and this finishing agent put up better self -cleaning effect to oil stain. In addition, the suit fabric after being washed still remain good self-cleaning performance.
