eCO2Dye

eCO2Dye has developed a waterless textile dyeing process and equipment for dyeing.

eCO2Dye has developed a waterless textile dyeing process and equipment for dyeing. The process uses carbon dioxide as the solvent for dyeing as opposed to water as the medium in conventional dyeing. Their Process for dyeing polyester offers the following advantages versus conventional dyeing in water • CO2 replaces water as the dye solvent • Saves energy • Uses fewer and less chemicals • Generates practically no waste streams • Carbon dioxide is recycled and not vented • Reduces the number of process steps • Simplifies dyeing chemistry • Reduces plant footprint • Flexibility in site location
