摘　　要：采用超临界二氧化碳染色装置,使用分散红73、分散黄114和分散蓝56染料对芳纶1313纱线进行染色,研究不同工艺条件(染色温度、染色压力、染色时间及载体)对上染率的影响,获得优化染色工艺。结果表明,上染率随着染色温度、染色压力的升高而增大;载体的使用对上染率的影响更为显著,使用载体染色时,在150℃、45 MPa的超临界条件下染色40 min可以达到满意的染色深度和染色牢度。Nomex yarn 1313 was dyed with disperse red 73,disperse yellow 114 and disperse blue 56 in supercritical carbon dioxide dyeing device.The influences of different process conditions(dyeing temperature,pressure,time and carrier)on the dyeing rate were studied to obtain an optimized dyeing process.The results showed that the dye uptake increased with the increase of temperature and pressure.The use of carrier had a more significant effect on the dye uptake.When using carrier dyeing,satisfactory dyeing depth and color fastness could be achieved under supercritical conditions of 150℃ and 45 MPa for 40 min.
