Abstract
Dyeing is the art of imparting hues and tints to yarns, fabric and other materials by employing colouring matter. Colouring matter can be obtained from both natural and synthetic sources. Synthethic dyes impart vibrant colour and are widely used but it causes carcinogenicity and inhibition of benthic photosynthetic. Recent reviewed of interest in the use of natural dye in textile colouring is due to the stringent environmental standard imposed by many European countries in response to the toxic and allergic reaction associated with synthethic dyes. Germany was the first to take initiative to put ban on numerous specific azo-dyes for their manufacturing and applications. Netherlands, India and some other countries also followed the ban (Patel, 2011) .A varieties of Colour, shades from vibrant jewel tones to dusky heathers and pastels can be obtain from different sources. Various methods are used for colour extraction as well as different extraction procedure depending upon the type of yarns or fabric differes. They are considered as eco-friendly, nontoxic, medicinal properties fitting into similar trends of repurposing, up cycling which is very important for maintaining environmental balance.
