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. |
