摘　　要：以葡萄糖为还原剂对植物靛蓝进行还原,研究还原工艺中各因素对还原性能的影响,并通过正交分析优化工艺。最佳还原工艺为:以KCl-NaOH为碱剂,植物靛蓝10 g/L,葡萄糖40 g/L,pH=12.4,还原温度55℃,还原时间为25min。所染阳离子改性棉织物染色性能明显提升,K/S值与保险粉还原接近,耐湿摩擦色牢度可达3~4级、耐皂洗色牢度中沾色和变色牢度均达3~4级。The research mainly focused on the reduction of plant indigo with glucose as reducing agent.A variety of influences on reduction performance were examined,and an orthogonal analysis was used to optimize the procedure.The research shows that optimum reduction conditions are 55℃for 25 min with plant indigo 10 g/L and glucose 40 g/L,pH=12.4and KCl-NaOH as alkaline agent.The dyeing property of the cationic modified cotton fabric is obviously improved and its K/S value is close to Sodium dithionite,the wet rubbing fastness reachingGrade 3-4,staining and changing colorfastness to washing reachingGrade 3-4.
