摘　　要：采用在线监测系统,对超临界CO2流体的形成及其对活性分散红GG染料的溶解、上染真丝纤维过程中流体溶解染料的实时变化和染后系统残留染料的清洗进行了探讨。结果表明,当系统压力和温度超过临界点时,出现均相的超临界CO2流体;溶解时间达120 min,染料溶解达平衡;染色时间超过60 min,超临界CO2流体中染料浓度明显下降。该系统实现了很好的在线测试和监控。The formation of supercritical CO2 fluid, the dissolving of reactive disperse dye Red GG, the real-time change of dye concentration in supercritical CO2 fluid during silk dyeing, and the clearing of residual dyes in dyeing system are investigated with an on-line monitoring system. The results indicate that homogeneous supercritical CO2 fluid is formed when pressure and temperature exceed the critical point. The dyes reach dissolving equilibrium under dissolved time of 120 minutes. The dye concentration of supercritical CO2 fluid drops obviously under dyeing time of more than 60 minutes. The system can realize on-line testing and monitoring.
