Abstract

Environmentalists are usually involved about the unbridled use of artificial dyes in the material enterprise as they lead to water, air pollutions and exceptional troubles related to waste water disposal. Natural dyes have gained a space starting in the area of fabric coloration. They are extra well matched with the environment in contrast to synthetic dyes because they are eco-friendly, non-allergic, non- toxic and also they are biodegradable. Due to the recognition amongst human beings involving the environmental and health risks elated with the use of artificial dyes, the craze for the apparels dyed with herbal dye is growing exponentially. The current study focused to produce various shades on the cotton fabric by using the combinations of Camellia sinensis & Portulaca grandiflorum, Macrotyloma uniflorum & Vigna radiata, Punica granatum & Mentha piperita with two different extraction methods such as Aqueous extraction and Alkaline extraction. The alum is used as mordant. The colour fastness was analysed and assessment confirmed that all dyed fabrics could withstand colour fastness test moderately. Further to discover precise chromophores in dye extracts and their molecular configurations due to mordants, FT-IR spectroscopy was employed.
