涤纶织物在超临界二氧化碳流体中的染色研究

Dyeing of Terylene in Supercritical Carbon Dioxide Fluid

利用在超临界二氧化碳流体中加入分散染料的方法,对涤纶织物的染色效果进行了研究。考察了影响染色的三个主要因素(温度、压力、染色时间)对上染量的影响,并测定了涤纶织物的上染量和色牢度。实验结果表明,当超临界二氧化碳染色的工艺条件为温度90℃、压力28MPa、染色时间1h时,涤纶织物的染色质量较好。

The influence of temperature, pressure and time on the uptake in dyeing Terylene with Disperse RED 176 using supercritical carbon dioxide fluid was studied, and the colour fastness and yield of the dyed terylene fabric were determined.
