A Study on Dyeability with Chitosan and Silane treatment on Natural Dyeing

In this study, one of disadvantages is to improve the durability of natural dyeing. In order to enhance linkage of Chitosan or Linkage of between Chitosan and cotton fabrics, effect of increasing amount of Silane on Chitosan durability and possibility of using Chitosan as natural mordant were reviewed. After treatment of chitosan with silane, color effect is similar to dyeability used metal mordant. And the durability's washing fastness and air permeability as using chitosan with silane is better than treatment of metal mordant. Chitosan with silane can perform the natural mordant.
