In this research, extraction of tannin as a natural mordant from tamarind seed coat. Tannin was extracted from tamarind seed coat using hot aqueous method. The qualitative analysis was carried out with various reagent and melting point determination for its purity were performed. The natural dye was extracted from rhizomes of turmeric by using aqueous method. The extracted tannin was employed as a natural mordant alone and in combination with metal mordant namely copper sulphate for wool yarn and dye using natural dyes. The visual colour strengths of all dyed wool yarns with and without mordant were compared. The pre-mordanted yarns on dyeing gave better color strength than the dyeing obtained without mordanting.
