According to the abstract released by the Intellectual Property India: "Natural Turmeric Dyeing with Biodegradable Bath Solution on Cellulosic Fiber Substrates of Cotton and Viscose for Aesthetic and Functional Values Abstract The present invention introduces an eco-friendly and sustainable textile processing system for dyeing cellulosic fiber substrates, specifically cotton and viscose, using natural turmeric in combination with a biodegradable bath solution. The proposed system comprises a cotton textile substrate, natural turmeric as a primary dyeing agent, a biodegradable bath solution for effective fixation, and a controlled application bath to ensure uniform dye transfer. Unlike conventional synthetic dyeing methods, the proposed approach eliminates harmful chemicals and enhances user safety while maintaining environmental compatibility. The process involves pre-treatment of the textile substrate, preparation of turmeric dye solution, and integration with a biodegradable bath medium to facilitate efficient dye absorption and fixation. The resulting fabric exhibits improved color strength, wash fastness, and functional properties such as antimicrobial and skin-friendly characteristics derived from turmeric's inherent bioactive compounds. Experimental validation demonstrates that the dyed fabrics retain color stability under various washing conditions, including exposure to water, detergents, and shampoo solutions, with minimal dye leaching. Furthermore, the invention enables the incorporation of natural dye combinations to achieve varied color shades without compromising functional benefits. This system significantly reduces environmental pollution, enhances textile sustainability, and promotes the use of renewable natural resources. The developed method is highly suitable for applications in healthcare textiles, innerwear, outerwear, and home textiles, offering both aesthetic appeal and therapeutic value. Overall, the invention represents a novel advancement in green textile technology by integrating natural dyeing with biodegradable processing for improved performance, safety, and ecological balance."
