DryDye technology is a polyester fabric dyeing process that uses no water, 50% fewer chemicals and 50% less energy than the traditional fabric dyeing process. It usually takes 25 litres of water to dye a t-shirt; not with DryDye. Instead of using water as the dye medium, dye is injected into the fabric using compressed carbon dioxide. After the dyeing cycle, the carbon dioxide is gasified, so that the dye condenses and separates from the gas. Thus, the clean carbon dioxide can be recycled and pumped back to the dyeing vessel.
