提高K型活性染料在真丝绸上固色率的研究

Improving K-Type Reactive Dye Fixation Yield on Silk Fabric

在K型活性染料上染真丝绸的过程中加入三种叔胺类化合物:烟酸、吡啶,三甲胺,研究了染色pH值、温度、时间及各叔胺类化合物的用量对活性染料在真丝绸上固色率的影响,在此基础上确定了叔胺类化合物的最佳应用工艺。结果表明,与常规染色工艺相比,加入叔胺类化合物可使K型活性染料在中性条件下上染真丝绸并提高其固色率。此外,染色织物的各项牢度指标均符合服用要求,且染后纤维受损伤程度较小。

The effects of pH value,temperature,time and dosage of various tertiary amines on the fixation yield of K-type reactive dye when dyeing silk with addition of tertiary amines in the dye bath are investigated and the optimal dyeing process is determined.
