Cotton dyes Cotton Inc. (Cary, N.C.; www.cottoninc.com) and Archroma (Reinach, Switzerland) have collaborated to present what they believe is the first ever dye derived from cotton-plant residues. EarthColors is Archroma’s method of creating dyes in warm, ternary shades from natural waste from the agricultural or herbal industry. The patented technology addresses two key concerns of the textile industry: sustainability and traceability. These sulfur-based dyes are designed for use on cellulosic fibers, such as cotton. Up to now, most dyes in the textile industry have been synthetic, derived from petrochemicals. The global volume of cotton harvesting and ginning byproducts — which includes burs, stems, immature bolls, lint, sticks, and leaves — can be as much as 3 million ton/yr, according to Archroma. One 480-lb bale of cotton, for example, can produce 150–200 lb of usable byproducts.
