Supercritical fluid extraction can reduce the extraction times of textile substrates and the amount of solvent required for the analysis of extractables. Researchers investigating the use of supercritical fluid technology for analytical, process, and environmental applications in polymers, fibers, and txtiles are studying the solubility and transport aspects of supercritical fluid extraction. Supercritical fluid chromatography measured the retention times of four different disperse dyeings used in supercritical carbon dioxide to dye polyethylene terephthalate. Calculations of relative solubilities indicated that longer retention times resulted in lower relative solubility. Supercritical fluid dyeing produced significantly greater depth of shade than did aqueous dyeing. Control of fluid recirculation and dye solubility in supercritical carbon dioxide were important parameters.
