Conventional textile dyeing requires substantial amounts of water. On average, an estimated 100-150 liters of water is needed to process one kg of textile materials today. Industry analysts estimate that more than 39 million tonnes of polyester will be dyed annually by 2015. Nike says it expects DyeCoo’s supercritical fluid carbon dioxide, or “SCF” CO 2 dyeing technology, to have a particularly positive impact in Asia, where much of the world’s textile dyeing occurs. As this technology is brought to scale, large amounts of water used in conventional textile dyeing will no longer be needed, nor will the commensurate use of fossil fuel-generated energy be required to heat such large sums of water. The removal of water from the textile dyeing process also eliminates the risk of effluent discharge, a known environmental hazard. The CO 2 used in DyeCoo’s dyeing process is also reclaimed and reused.
DyeCoo is believed to be the first company to successfully apply the SCF CO 2 process to the commercial dyeing of polyester fabric, and research is already underway to apply the technology to other natural and synthetic fabrics. SCF CO 2 technology is safely utilized at scale in other industries such as the decaffeination of coffee and the extraction of natural flavors and fragrances.
