In order to study the technology feasibility and the effects of the operating pressure, temperature and dyeing time on the dye uptake and the dye depth K/S, the experimental apparatus were set up and the experiments of dyeing poly(ethylene terephthalate) fibers with disperse blue 60 in supercritical carbon dioxide were con.
为了对该工艺的染色过程、适宜的操作条件及可行性进行研究,在自建的高压染色设备上,利用分散蓝60对涤纶进行超临界流体染色实验,考察上染率及染色深度K/S值随操作压力、温度和染色时间的变化规律,进而确定出最适宜的工艺操作条件为:压力28MPa,温度120cC和染色时间80min。
