The synthetic dyes which are of wide commercial importance cause severe atmospheric and environmental pollution. The present investigation was carried out to extract natural dye from green chili (Capsicum annum).The main coloring component in chili is oleoresin. The dye was extracted using solvent extraction method. A mordant is a substance used to set dyes on fabrics by forming a coordination complex with the dye which then attaches to the fabric. Two mordants – copper sulphate and ferrous sulphate were used in ratios 1:1, 1:3, 3:1.100% scoured cotton cloth was used for dyeing by three different techniques-pre mordanting, simultaneous mordanting and post mordanting. Fastness is the ability of a dye to remain permanent and not run or fade. Color fastness studies on the dyed cloth were undertaken. The mordants helped in fixing the dye to the fabric as well as improve the fastness properties of the dyed cloth. Different shades of yellow were obtained from the dye extracted from chili skin. These different shades are obtained from a single dye using the two mordants in different ratios. Good light fastness, good rub fastness and moderate wash fastness was observed in fabrics dyed with the dye extracted from Green chili.
