摘　　要：橘皮色素是一种天然无害植物染料,通过单因素试验和正交试验,探讨了橘皮色素最佳提取工艺及橘皮色素对羊毛纤维的最佳染色工艺,并测试了染色织物的色牢度。结果表明,橘皮色素提取最佳工艺为:90%乙醇溶液,料液比1∶5(1 g橘皮对应的浸提溶剂量),70℃下浸提90 min,重复4次。橘皮色素对羊毛纤维的最佳染色工艺为:橘皮提取色素质量浓度10 g/L,50℃始染,以1.5℃/min升温至100℃,保温70 min,降温至60℃,加入6%(omf)氯化铈,升温至90℃,保温30 min,浴比1∶50。染色后织物各项色牢度均满足服用性能的要求。The orange peel pigment is one kind of a natural harmless plant dyestuff. Through single fac- tor experiment and orthogonal experiment, the optimal extraction process of orange peel pigment and the optimal dyeing process of wool fiber with the pigment are discussed, and the color fastness of the dyed fabric is also tested. The results show that the optimal extraction process of orange peel pigment is： 90% ethanol solution, the solid-liquor ratio of 1：5 （the amount of solvent extraction of 1 g orange peel）, extracting at 70 ℃ for 90 min, and 4-cycle extraction. The optimal dyeing process of wool fiber with orange peel pigment is： orange peel pigment concentration of 10 g/L and initial dyeing temperature at 50 ℃, rising to 100 ℃ at a speed of 1.5 ℃/min and holding for 70 min, then cooling to 60 ℃ and adding 6%（omf） cerium chloride, rising to 90 ℃ and holding for 30 min, bath ratio of ! ： 50. The color fastness of the dyed fabric is up to the requirement of wearability.
