摘　　要：针对传统的空气氧化制约了植物染料青黛现代化生产的问题,研究用含天然靛蓝的植物染料青黛对羊毛织物进行染色,并利用双氧水代替空气对其进行氧化,探索青黛染料染色的工业化生产可能性。通过改变工艺参数,研究双氧水浓度、氧化温度、氧化液pH值、氧化时间等因素对染色效果的影响,并对比了双氧水氧化和空气氧化的效果。结果显示双氧水氧化后染样的K/S值较高,染色牢度与染色重现性较好。与传统的空气氧化相比,采用双氧水氧化易于控制生产工艺,更适用于现代化生产。Traditional air oxidation of the plant dye indigo naturalis have hindered its modem production. For this reason, this article studied dyeing wool fabrics with indigo naturalis which contained natural indigo and oxidized it with hydrogen peroxide in replace of the air, to explore the possibility of industrial scale dyeing using indigo naturalis. The effects of hydrogen peroxide＇s concentration, oxidative temperature, pH value and time on the result of dyeing were studied. The oxidative effect of hydrogen peroxide is compared with that of the air. The results indicated that the K/S value, color fastness and reproducibility of the dyed fabric employing hydrogen peroxide oxidation were better. Compared to the traditional air oxidation, hydrogen peroxide oxidation is easier to control and more applicable to modem production.
