【摘要】：针对传统水介质染色过程水耗、能耗、污水排放量大的难题,采用具有自主知识产权的1 000 L复式超临界CO_2流体染色装备系统对涤纶筒纱进行无水染色工程化生产。基于研发的复式超临界CO_2流体无水染色装备,系统介绍了其超临界流体染色工艺过程;同时,利用独特设计的筒纱染色釜,进行了涤纶筒纱超临界CO_2流体无水染色工艺研究。结果表明:利用研发的1 000 L复式超临界CO_2流体无水染色装备,可获得较高染色深度的筒纱,且染色产品具有良好的匀染性;此外,染色涤纶筒纱的耐水洗、耐摩擦色牢度可达到4~5级以上,耐日晒色牢度可达到6级以上,满足了工程化生产的需要。
[Abstract]:In view of the problems of water consumption, energy consumption and sewage discharge in the dyeing process of traditional water medium, Using the 1000L double supercritical CO_2 fluid dyeing equipment system with independent intellectual property right to carry on the waterless dyeing engineering production to the polyester yarn, based on the research and development of the double supercritical CO_2 fluid anhydrous dyeing equipment, The process of supercritical fluid dyeing was systematically introduced, and the special design of the dyed kettle was used. The process of supercritical CO_2 fluid anhydrous dyeing for polyester yarn was studied. The results showed that the yarn with higher dyeing depth could be obtained by using the 1 000 L double supercritical CO_2 fluid anhydrous dyeing equipment, and the dyeing product had good leveling property. In addition, the color fastness of dyed polyester yarn to washing and washing can reach 4 ~ 5 grade or more, and the color fastness to sunlight can reach more than 6 grade, which meets the need of engineering production.
