Abstract: 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.
