APPLICATION OF SUPERCRITICAL CARBON-DIOXIDE IN FINISHING PROCESSES

An overview of a new dyeing process for dyeing synthetic fibres and fa brics is presented. The use of disperse dyes in supercritical carbon d ioxide as dyeing medium completely avoids water pollution and the need of drying. Laboratory results which show that excellent levelness and fastness can be achieved on poly- (ethylene terephthalate) and other synthetic materials are presented. The technical development is descri bed and other potential uses of supercritical fluids in the textile fi eld are discussed.
