Novel methods have been developed by mills and researchers due to competition in the denim industry. Thus dyeing properties of natural dye, M. tenuiflora extract, with different mordants were investigated. Various colour effects were obtained with different mordants. Highest colour strength values were obtained at indigo dyed fabrics due to indigo. Highest L∗ values were observed in the case of both Al and Pb mordanted fabrics. Vividness values increased with Ni mordant. Moderate light fastness values were observed. Although indigo has good light fastness values, light fastness was observed at moderate levels owing to M. tenuiflora extract. Poor wet and dry rubbing fastnesses were obtained in indigo dyed fabrics due to low rubbing fastness of indigo.
Natural dyes have been getting more important due to their advantages that are aforementioned. Our further work will be focussed on the use of various natural dyes in the production of denim goods
