Environmental pollution due to the discharge of dyeing industry effluents is the matter of major concern now-a-days. Upto the end of 19th century natural dyes were the main colourants for textiles. Recently, interest in the use of natural dyes has been
growing rapidly due to the result of stringent environmental standards imposed by many countries in response to toxic and allergic reactions associated with synthetic dyes1. Until about 150 years ago all dyes were natural substances, derived mainly from plants and animals. The natural dyes present in plants and animals are pigmentary molecules2 which impart colour to the materials. With the world becoming
more conscious towards ecology and environment, there is greater need today to revive the tradition of natural dye and dyeing techniques as an alternative of
hazardous synthetic dyes is an extremely crude.
