Eco Friendly Dyeing with natural dye - Areca nut; enhancing colour fastness with natural mordants (Myrobalan, Lodhra and Pomegranate) and increasing the Antibacterial Activity

摘要

The main aim of the study is to use natural mordants to improve the colour fastness of the natural dyes in tandem with environment and reproducible methods. To accomplish the formulated objective, experiments in various proportions with the natural dyes and natural mordants to achieve the colour fastness and visual inspection of the dyed samples and analyzing the colour fastness tests using standards were planned . During the pilot study, it was experiential that pre mordanting method is most effective in achieving colour shades and colour fastness than the post and simultaneous mordanting method. Comparative study was conducted between the three mordants on bases of colour change, colour (Light, wash and perspiration) fastness, depth of shade dye. Lodhra showed excellent colour fastness and also allows the dyes to show the real colours, whereas pomegranate and myrobalan covers up the dye's colour with their natural colour. Pomegranate displays excellent anti bacterial activity than the other two mordants. While conducting the study it was also observed that the effluent generated from this whole process is not harmful and can be used for farming /gardening activities. The water used for dyeing and mordanting can be reused by simple steps of recycling. The study authenticates natural dyeing with natural mordanting method is an excellent example for conserving environment yet able to colour the cotton fabric with various shades.
