Abstract
Natural dyes in carpet industry have been tried as a revived area of interest, in deference with the growing demand in importing countries for nearly a decade now. Natural dyes can be deemed to be more eco-friendly provided the dyeing technology and mordanting aspects are well understood and regulated at the shop floor level so that the fastness properties of the natural dyes are improved on one hand, and the use of metallic mordants are restricted to the minimum and safe levels, on the other.In the present study, wool was dyed using different natural dyes and mordants to obtain a wide gamut of colours. A shade card of these natural dyes was developed on wool using selected mordants. The colour values of natural dyed wool were analyzed in terms of L*a*b* values. Samples were assessed in terms of the colour fastness to washing, rubbing and light.The effect of chemical washing on colour values and fastness properties of natural dyes on wool was studied. There were significant changes in colour values of most of the natural dyes after chemical washing. The colours however, remain stable after chemical washing. The wash and rub fastness for all the dyes was good except for few after chemical washing. The light fastness of all the natural dyed samples was good and above 3. Hence, it is observed that it is possible to select a gamut of colours for carpets from the shade cards of natural dyed wool yarns.
