Fruit peels show dye removal potential

DHAKA — Researchers at Bangladesh University of Textiles have demonstrated that fruit peel extracts can replace conventional colour-removing agents in laboratory discharge printing trials on cotton.

The study, published in Discover Chemistry, tested orange and pineapple peel extracts on knitted cotton dyed with carmine and navy reactive dyes. Pineapple peel extract reduced colour strength by 95.6% on carmine-dyed fabric, slightly exceeding two conventional agents.
