摘要
以葡萄糖作植物靛蓝染料的还原剂,对棉织物进行染色。通过单因素分析和正交试验法优化干缸还原工艺和染色工艺。结果表明,当植物靛蓝用量为10%(om f),干缸还原浴比为1∶50时,优化的植物靛蓝葡萄糖还原工艺为葡萄糖30 g/L,烧碱10 g/L,还原温度50℃,还原时间20 min;染色浴比为1∶20时,优化的染色工艺为氯化钠用量100 g/L,染色温度40℃,染色时间100 min。在相同条件下,以葡萄糖作为植物靛蓝染料的还原剂,染色棉织物的色牢度与传统保险粉工艺接近,K/S值略高,且染色废水的CODC r值较小。
Cotton fabric is dyed with natural indigo dyes using glucose as a reducer instead of sodium hydrosulfite, and the reduction and dyeing processes are optimized via single factor tests and orthogonaf experiments. The results show that under natural indigo dyes of 10% （omf） and bath ratio of 1 ：50, the optimum reduction process is at 50 %; for 20 minutes with glucose 30 g/L and caustic soda 10 g/L; under bath ratio of 1 ：20, the optimum dyeing process is at 40 ℃ for 100 minutes with sodium chloride 100 g/L. Compared with conventional dyeing process with sodium hydrosulfite, the new dyeing process with glucose features similar color fastness, higher K/S value and lower CODcr of dyeing effluents.
