Abstract
An organic substance with a distinctly blue colour is called indigo dye. It is among the earliest dyes made from the leaves of some Indigofera plants. Natural indigo has been utilized for thousands of years in traditional cultural applications, like batik and tie-dye. But as industrialization has increased, synthetic indigo has become a cost-effective, high-purity, better-coloured and better-produced substitute for indigo in the textile industry. However, this leads to a significant build-up of chemical waste in the environment, making the textile sector the most polluting in the world. People are, therefore, becoming more interested in eco-friendly fashion designs for apparel, that is not only non-toxic but also free of health risks. Given that natural indigo is environmentally-friendly and biodegradable, it becomes even more significant as a green dye in this perspective. Thus, this paper covers the chemistry, background information and colouring procedure of natural indigo as well as the cost-effective and environmentally-friendly alternatives to synthetic indigo and the microbial manufacture of bio-indigo.
