摘　　要：为系统研究新疆紫草色素在羊毛织物染色中的应用效果,以正交试验优化了紫草色素在羊毛织物上的染色工艺条件。结果表明,采用直接染色工艺,在色素质量分数4%(omf)、温度80℃、pH 4.0及时间60 min的条件下,织物可获得较高的染色深度(K/S值9.2)。将铝盐、铁盐作为媒染剂,用新疆紫草色素对羊毛织物分别进行预媒染、同浴媒染以及后媒染染色,染后织物的各项色牢度比直接染色法均有所提高。In order to study the dyeing effect of Arnebia euchroma pigment on wool fabrics,the dyeing condi⁃tions are optimized by orthogonal test.The results show that the fabric can obtain a higher dyeing depth(K/S value 9.2)under the conditions of pigment concentration 4%(omf),temperature 80℃,pH 4.0 and time 60 min.Using aluminum salt and ferric salt as mordant,the wool fabric is dyed with Arnebia euchroma pigment using pre-mordant,one-bath mordant and post-mordant method respectively.The color fastness of the dyed fabric is improved compared with that of direct dyeing.
