Title: Reactive dyeing of cotton fabric assisted with new salt A
Abstract: In order to improve dyeability of cotton with reactive dyes,cationization and aminization cotton fabric was carried out with new-salt A pre treatment.FT-IR analysis showed that a lot of amido groups were grafted onto cotton fiber.Optimum pretreatment process was determined as follows:new-salt A 6 g/L,bath ratio 1:20,treating at 80℃for 10 minutes.When modified cotton fabric was dyed in deep shades with reactive dyes,dosage of salt reduced by more than 60%;the shade was almost unchanged;the dyeing properties were improved,such as adsorption rate,reactivity to reactive dyes,dye uptake,fixation rate,soaping fastness and evenness,while rubbing fastness decreased slightly.
