Natural Black Dyeing: A Sustainable Way Ahead

Abstract

Traditionally, the methods used for natural black dyeing, have been riddled with problems due to complexities of procedures involved, low colour yield and poor fastness properties. In the present study, an attempt was made to produce a good black hue on Cotton, Woollen and Silk fabrics using a single or a suitable combination of Natural dyes of primary colours - Red, Blue, and Yellow along with mordanting. The dyed samples were analysed for their colour value in terms of their L*a*b* and K/S measurements and fastness properties to light and washing. Among all the dyes samples the ones within the ‘Circle of Tolerance Limits’ were selected as close to ideal black.
