Journal Textile Coloration and Finishing Year / Vol., Issue, Month 2019 / V.31,no.1,Mar Title Supercritical CO2 Dyeing and Finishing Technology - A Review Authors Gyoyoung Lee, Juwon Chae, Sang Oh Lee1, Sam Soo Kim and Jaewoong Lee* Institution/Affiliations Yeungnam University Pages/Total page pp.48 ~ 64 / 17 Language Korean Abstract Abstract With evolution in the production environment of the textile industry, the need for non-water-based dyeing technologies and eco-friendly process facilities in the dyeing and processing stages has increased. In recent years, supercritical fluid dyes have been developed and commercialized in Europe, centering on this demand. However, so far, such dyes have been mainly applied in the processing of PET fibers. Basic research has mainly involved investigation of dyeing by supercritical carbon dioxide or solubility of such dyes, and more in-depth research should be continuously carried out. In this review, we describe the types and characteristics of supercritical fluids that exhibit specific properties at pressures and temperatures over the critical point. In addition, the state of the art in the dyeing and processing technology using supercritical fluids and associated, processing problems, environmental regulation, and wastewater treatment issues are described in detail. We hope this review can contribute to the supercritical fluid technology being further developed as an environment friendly dyeing processing method. Furthermore, we expect that the technique can be used as a means of ensuring different, high-quality dyed products.
