Natural Dyeing of Cotton with Red Amaranth: A Study on its Efficiency and Fabric Properties

The textile industry is under increasing observation for its heavy reliance on various artificial and synthetic dyes, which pose severe environmental and health risks. To address these challenges, this research investigates the potential of Red Amaranth (Amaranthus tricolor) as a sustainable natural dye source for 100% cotton textiles. The study focuses on the extraction of water-soluble betalain pigments and the optimization of the dyeing process using mordants such as Alum. Beyond aesthetics, the dyed fabric was evaluated for its antioxidant properties. The findings suggest that Red Amaranth dye is a viable, non-toxic alternative for the development of Adaptive Garments designed for elderly, bedridden patients, where skin safety and functional benefits are prioritized.
