Colour matching on wool using natural and synthetic dyes

Abstract

Wool fabric samples were dyed using natural dyes and mordants singly and in their binary mixtures. Computer colour matching system was used to evaluate these dyeings and generate matching dyeing recipes for synthetic trichromatic acid dyes which are ecofriendly. After dyeing with acid dyes, the natural dyed and acid dyed samples were evaluated for colour

differences and it has been observed that in almost all cases, good matchings are observed for the natural dyed wool samples. This indicates that selective classes of synthetic dyes, which exhaust to higher levels and have proven non-toxicity, could be used with due concern to ecology and economy.
