EXTRACTION AND APPLICATION OF SOME NATURAL FABRIC DYES FROM AKOLA REGION

Vaishali S. Patil*, Sara Tabassum Naseem Khan

ABSTRACT

Natural dyes are renewable source of colouring materials. They are dyes or colorants derived from plants, invertebrates, or minerals. The majority of natural dyes are vegetable dyes extracted from plant sources such as roots, berries, bark, leaves, wood and other biological sources such as fungi. Besides textiles it has application in colouration of foods, medicine and in handicraft items. In present scenario environmental consciousness of people about natural products, renewable nature of materials, less environmental damage and sustainability of the natural products has further revived the use of natural dyes in dyeing of textile materials. In synthetic dyes, the most common substrate for dye production is petroleum, which is a non-renewable source of energy. Synthesis generates a large amount of effluent which contains toxic chemicals generated as side products. These dyes also react with various other organic by products of the effluent, forming harmful aromatic complexes that result in mutations and cancers in aquatic animals. Recent studies have shown that dyes have genotoxic, cytotoxic, and mutagenic properties when exposed in greater concentrations to living organisms. They can also cause DNA fragmentations, allergies, skin irritations, and malfunctioning of various organs when acted upon by different biotic and abiotic factors due to the formation of toxic breakdown products. So there is need of significant research work to explore the potentials of natural dyes before its important application to textile substrate.
