Textile dyes from cotton waste for dyeing cotton

Written by John Mowbray

CARY – Cotton Incorporated and Archroma have joined forces to develop what it believed to be the first ever cellulosic textile dyes derived from cotton biomass, which essentially means the technology to dye cotton – from cotton – is now commercially available to the global textile industry.

The new dyestuff for cellulosic fibres is the latest addition to Archroma’s ‘EarthColors’ range of sulphur-based dyes that are derived from waste biomass, as opposed to being synthesized using oil-based derivatives. The new dye uses by-products of cotton harvesting as a base instead of oil to give knit and woven cotton fabrics dyed in a variety of warm, soft, natural brown shades that will be shown at this week’s Premiere Vision trade show in Paris.

Cotton Inc. says the new dyes offer both sustainability and traceability for retailers and brands.
