Abstract:Measurement equipments and methods of dye solubility in supercritical CO2 fluid were reviewed. Influence rule of supercritical CO2 fluid process parameters and dye chemical structures on the solubility of disperse dyes was analyzed. Solubility data of disperse dyes in supercritical CO2 fluid in recent 20 years were then summarized, and solubility increasing techniques in supercritical CO2 were introduced. It is pointed out that the deep analysis for the action principle and influence law of dye structures on their solubilities, the establishment of dye dissolution behavior database in supercritical CO2 and the research on combination dyeing and color matching should be carried out in the future.
