Harnessing Microalgae Biomass from Lake Taihu as a Natural Biocolorant Source for Sustainable Eco-Friendly Dyeing of Cotton with Ultrasonication

Most water bodies worldwide are infested with algae bloom and Lake Taihu is no exception, various techniques have been developed to harvest microalgae from as part of the lake cleaning program this results in a large biomass deal with. This study made use harvested biocolorants source for textile application also evaluated its dyeing characteristics mercerized bleached cotton. The fabrics were dyed either ultrasound or bath method. method improved dye extraction yield 17.8% conventional 26.7%, which was enhanced 33.2% addition HCl (1 cm). effective at improving uptake reduced temperature when compared produced different shades color after mordants. had good fastness properties laundry, crocking light. showed ultraviolet protection factor. potential colorants will provide an alternate that environmentally friendly.
