摘　　要：用天然靛蓝染料对牛仔布纱线进行染色试验,探讨了碱用量(石灰)、染色温度、染色时间对染色深度的影响,得到了最适宜的染色工艺,并对比测试了该染料和化学靛蓝染色的染色深度和各项染色牢度。试验表明,天然靛蓝具有良好的染色深度和染色牢度,可代替化学靛蓝用于牛仔布的染色,特别是用于贴身穿着的衬衣和牛仔裤的中浅色染色,对人体无毒无害。The plant indigo pigment was used to dye denim yarns in this paper. The influence of dyeing depth was evaluated by analyzing sodium hydroxide dosage, dyeing temperature and time. The optimum condition of the dyestuff was obtained. The dyeing depth and color fastness of this dyestuff and chemical dyestuff were compared. The experiment showed that the dyeing depth and color fastness of plant indigo were better, which could substitute for chemical dyestuff dyeing denim fabrics, especially dyeing skin touch shirt and middle light color of jeans. Furthermore, it was non toxic and harmless.
