Abstract: Textile dyeing and printing industry is one of the most polluting sectors from an ecological point of view. There is need to approach new strategies, methods, materials for dyeing treatment of cotton fabric with natural and synthetic dyes using environment benign route. In the present study, biopolymer (chitosan) was taken for the pre-treatment of cotton fabric for improving the dye uptake of natural dyes and comparison was made with aluminium potassium sulphate (alum) on the basis of colour properties of dyed fabrics. Standardization of chitosan treatment and dyeing process for onion skin dye was done. It was found that the chitosan treated onion skin dyed fabric showed higher dye absorption (66.17 %), colour strength (16.52) than alum treated dyed fabric (55.98%, 12.21 k/s) respectively. Thus it is concluded that chitosan treatment enhanced the colour properties of cotton fabric without using any harsh chemicals and capable enough to replace use of salt and alkali used as mordant in dyeing of cotton.
