FeyeCon started textile dyeing with carbon dioxide in 1998 and has continuously developed the process of dyeing with CO₂. This method uses less or no chemicals or water than conventional methods. Furthermore, CO₂ dyeing requires less energy and time, which dramatically reduces the production costs. Ten years of development were a good exercise to reduce the costs of the dyeing process so that the process stays profitable for the dye-houses. Several breakthrough engineering designs were documented in 10 patents.
