摘　　要：探讨了自制低温染色助剂WLDCY-100用量、染浴pH值、染色温度对羊毛低温染色下的上染百分率的影响。结果表明:WLDCY-100能显著改善羊毛酸性染料在80℃条件下的染色性能。针对酸性染料用量为2%(owf)来说,优化工艺为低温染色助剂WLDCY-100用量1%(owf),平平加O用量0.5%(owf),pH值4;浴比1∶50,染色温度80℃,时间45 min。该助剂的羊毛低温染色工艺的羊毛耐洗色牢度可以达到沸染的效果,由于减少一道水洗工艺,干湿摩擦牢度较传统工艺低。Low-temperature dyeing auxiliary WLDCY -100 was used in low temperature dyeing of wool yarn. Dye-uptake was influenced by the dosege of WLDCY - 100, pH value, the dyeing temperature, which were studied. The results showed that the WLDCY - 100 agent markedly improved the wool fiber dyeing performance with acid dyes at 80 ℃. As to 2% （owl） acid dyes, optimum dyeing condition were temperature 80 ℃ , time 45 min with low-temp dyeing auxiliary WLDCY -100 1% （owl） , alcohol ethoxylate 0.5% （owf） , pH value 4, bath ratio 1：50. Color fastness to washing of the low-temp dyeing of wool yarn with WLDCY - 100 was the same as boiling dyeing. Color fastness to rubbing was lower than the traditional process, since the low-temp dyeing process was lack of washing.
