TY - JOUR TI - DYE SOLUBILITY IN SUPERCRITICAL CARBON DIOXIDE FLUID AU - Yan Jun AU - Zheng Lai-Jiu AU - Du Bing AU - Qian Yong-Fang AU - Ye Fang JN - Thermal Science PY - 2015 VL - 19 IS - 4 SP - 1311 EP - 1315 PT - Article AB - Supercritical carbon dioxide fluid is an alternative solvent for the water of the traditional dyeing. The solubility of dyestuff affects greatly the dyeing process. A theoretical model for predicting the dye solubility is proposed and verified experimentally. The paper concludes that the pressure has a greater impact on the dyestuff solubility than temperature, and an optimal dyeing condition is suggested for the highest distribution coefficient of dyestuff.
