摘要
利用单因素实验研究了染浴pH值、染色温度、氯化镧用量与加入方式等因素对天然栀子黄色素上染羊毛纤维的影响。通过正交试验,得出天然栀子黄色素采用氯化镧上染羊毛纤维较合适的条件为:染浴pH值4,染色温度90℃,保温阶段加入7%(owf)氯化镧,上染百分率达到96.27%;氯化镧的加入能明显改善羊毛的皂洗牢度,皂洗牢度可达4级。羊毛纤维的断裂强力略有下降。
Application of rare earth chloride in dyeing wool fiber with gardenia yellow colorant was studied. Variables such as pH value, temperature, concentration of lanthanum chloride and its adding mode in the dyeing process were investigated. Through one-way and orthogonal tests,the optimum dyeing conditions were obtained as follows ：pH value of 4, concentration of lanthanum chloride 7% （owf） added during the constant temperature period, and the dyeing temperature was 90 ℃. Results showed that the dye uptake could be raised to 96.27% with excellent washing fastness and slight strength loss.
