Abstract

Water is a valuable resource both for life and because of its properties. Therefore, water scarcity and increasing environmental awareness cause worldwide concern. The textile industry generally
consists of processes with intense water consumption. Especially in the dyeing process, a lot of water is used. For this reason, the importance of dyeing studies aimed at reducing water use that increases day by day. In this study, one %100 polyester woven fabrics were dyed in dark and light shade in supercritical carbon dioxide (scCO2) media (waterless) and classic media (aqueous) and the dyeing process was evaluated by life cycle analysis (LCA) method in both media. SimaPro 9.3 program was used for the analysis and it was concluded that the environmental effect of dyeing cumulatively performed in the supercritical medium is less compared to dyeing in a classical aqueous medium, thus it is more advantageous.
