Abstract:

In order to promote the development of functional cotton textiles and improve the applicability of antibacterial finishing with nano silver in dyeing and finishing of cotton fabric , silver ammonia solution was applied to forming nano silver through in-suit reduction method. Combined with cotton fabric dyeing, the effects of nano silver loading on dyeing rate were investigated. Shade of treated fabric in silver ammonia solution finish in the wake of dyeing and dyeing in the wake of silver ammonia solution finish process was evaluated. Shade change of dyed fabric after washing ,antibacterial property and washing durability were determined. The results showed that influence on dyeing rate by loading nano silver was related to the concentration of silver ammonia solution and dye structure. Increasing the concentration of silver ammonia solution leaded to significant changes of shade and treated fabric in finishing in the wake of dyeing process changed more seriously. Besides, cotton textiles prepared in two process had favorable antibacterial properties and washing durability. The strength decreased by about 15 percent.
