低温染色助剂WWH在拉伸羊毛染色中的应用

Application of low temperature dyeing auxiliary WWH in the dyeing process of the stretching wool

以未拉伸羊毛和国产及进口拉伸羊毛为研究对象 ,研究了低温染色助剂WWH用量对羊毛染色性能的影响。试验结果表明 ,低温染色助剂WWH能降低羊毛的染色温度 ,低温染色后拉伸羊毛的染色牢度基本不变。低温染色助剂WWH的合理用量为 7～ 8g

In this paper,non-stretching,domestic and import stretching wool were employed as the dyeing substrates,the influence of the doses of low temperature dyeing auxiliary WWH on dyeing properties of wool was studied.The results showed that WWH can decrease the dyeing temperature of wool.The fastness of the stretching wool make no change approximately after low temperature dyeing.The recommended dose of WWH is 7～8 g/L.
