Chitosan : An Eco-Friendly Mordant for Natural Dyes

Abstract

Presently the art of dyeing with natural dyes has gained momentum with the ban imposed on certain synthetic dyes. In search of eco-friendly processes for dyeing with natural dyes research has been focused on identification and standardization of natural dyes. On these lines a study was undertaken to standardize chitosan as a mordant for selected dyes and to assess their colour fastness. Comparison of chitosan mordanted samples was made with that of other two eco-friendly mordanted samples of alum and ferrous sulphate to find the impact of chitosan as a mordant for natural dyes.
