摘要
在自建的高压染色釜上,利用新合成的六只分散黄染料(分散黄1、2、3、4、5和6)对涤纶进行SFD实验,考察操作温度、压力和染色时间对染色深度K/S值的影响,从而定出适宜的工艺条件,且对适宜工艺条件下的被染试样进行牢度测试评价。实验结果表明:操作压力、温度和染色时间对染色深度K/S值的影响显著;适宜的工艺操作条件:分散黄1～4为压力25MPa、温度120℃、染色时间100min,分散黄5为压力25MPa、温度110℃、染色时间100min,分散黄6为压力23MPa、温度110℃、染色时间100min,且较容易实现;不同染料具有不同的最大(平衡)染色深度K/S值,染料结构对牢度结果几乎没有影响;在适宜的工艺条件下可获得较好的牢度效果。通过研究,可充分显示SFD工艺的可行性和优越性,且这些新合成的分散黄染料可成功应用于SFD。
Supercritical fluid dyeing experiments of terylene with 6 newly synthesized disperse yellow dyes were carried out, and the effect of dyeing temperature, pressure, and duration on the colour depth K/S values were investigated. The optimal process conditions were determined and the dyed samples obtained under these conditions were tested and evaluated for their colour fastness.
