摘　　要：超临界CO2 流体的流速会影响染料在超临界CO2 介质中对涤纶织物的上染性能和染色均匀性。通过研究在不同超临界CO2 流速下的C .I .分散红 60对涤纶织物的上染性能和匀染性的影响 ,得出其影响规律。The CO 2 flow rate has important effects on the dyeing behaviour and levelness of PET fabric in supercritical carbon dioxide. The dyeing properties and levelness of PET dyed in supercritical CO 2 of varied flow rate with C.I.disperse red 60 are studied and the influence of flow rate on the dyeing behaviours is researched in this paper.

关 键 词：超临界CO2流体 流速 涤纶织物 染色 染料 匀染性
