Studies on Application of Natural Dyes on Natural Fibres

Ecological or environmental problems have become global in character and there is an urgent need worldwide to tackle these problems. The most famous environmental impacts related to energy and toxic chemical use, as well as ecological or social impacts comprising of low wages and poor working conditions are the major environmental problems needing urgent attention. These detrimental impacts demand sustainable changes not only in each phase of the textile life cycle, but also on a holistic systems-level. Environmental protection and production of quality textiles of international standards are two serious challenges before textile processors. Natural dyes/colors have been used historically throughout the world. However, their use has decreased to a large extent due to the arrival of synthetic dyes. In view of the toxic effects like allergy, mutagenicity and carcinogenicity of some of the synthetic dyes, the use of natural dyes has once again gained the interest.
