【Abstract】 In this paper, the dying operation process and technological parameter of disperse dyes for fabric under the condition of supercritical CO2 are studied. The fabrics are treated with surface-active agent and cellulose enzyme in pretreatment. The solubility, dye fastness, level-dyeing property, fabric strength and dying mechanism are analyzed based on the experimental results in supercritical carbon dioxide. The experimental result indicates that the flux of CO2 fluid has important influence on dyeing.更多还原
