Influence of Chitosan Finishing on Dyeing Effect

Abstract:

Treatment methods of silk fabric with chitosan and the dyeing of tussah silk fabric on low-salt condition were the subject of this study. The different treatment methods were used to find the influence of treatment methods on the dye ability. It was clear from the results that the color depth of the dyed fabric, the fixation ratio and dyeing rate of reactive dyes on silk fabric could be improved efficiently by the crosslinkling after the fabric was treated with chitosan.The optimal concentration of chitosan was 0.7% (w/v). The finishing effect of pretreatment was the best and the effect of post treatment was better than simultaneous treatment. The salt concentration could be reduced when the fabrics were treated with chitosan, but the degree of salt concentration reduction was not obvious.
