Due to environmental awareness created among masses worldwide by environmentalist and Green peace activist and hazards of certain synthetics dyes i.e. benzidine and certain azo-dyes producing among 22 types of cancerous amines, people have realized the potential of natural dyes and tried to use them as an alternative to synthetic dyes. Studies were conducted to extract the dye from myrobalan, gallnut and pomegranate and used them on mordanted wool and 27 shades were developed. L~* a~* b~* values and fastness properties were evaluated to determine the use of these dyes on commercial basis.
