摘　　要：针对靛蓝染料上染率低,染色时须多次浸轧的问题,采用液体石蜡作为棉纤维靛蓝染料染色介质,研究了高浓度靛蓝染料的还原工艺及棉纤维在靛蓝染料/液蜡体系中的浸染新工艺。结果表明,高质量浓度隐色体制备的最佳条件为:靛蓝染料30 g/L,NaOH 50 g/L,保险粉160 g/L,还原温度60℃,还原时间20 min。棉纤维在液蜡介质中的最佳浸染工艺条件为:棉纤维带液率80%,m(棉)∶m(隐色体)=1∶2,染色温度60℃,染色时间50 min,m(液蜡)∶m(棉)=50∶1。在最佳工艺条件下,一次染色棉纤维的K/S值可达到24.75。In view of the low dyeing rate of indigo dye and multiple times of padding during dyeing,liquid paraffin was used as the dyeing medium during the indigo dyeing process.The reduction process of high concentration indigo dye and the new dyeing process of cotton fiber in indigo dye/liquid paraffin system were studied.The results showed that the optimal conditions for the preparation of high concentration leuco were as follows:indigo dye 30 g/L,NaOH 50 g/L,sodium hypo-sulfite 160 g/L,and reducted at 60℃for 20 min.The optimal dyeing conditions of cotton fiber in liquid paraffin medium were as follows:the pickup of cotton fiber 80%,m(cotton)∶m(leuco)=1∶2,dyed at 60℃for 50 min,m(liquid paraffin)∶m(cotton)=50∶1.Under the optimum process conditions,the K/S value of the dyed cotton fiber reached 24.75.
