摘　　要：采用直接染色、同浴媒染法、预媒染色及后媒染对真丝织物进行红蓝草色素染色,分析媒染条件对织物K/S值及耐摩擦色牢度的影响。结果表明:最佳染色方法为后媒染法,即采用质量分数为4%(omf)的硫酸亚铁或3%(omf)的硫酸铜或硫酸铝钾为媒染剂,45℃媒染45 min,染色真丝织物的K/S值较高,颜色为棕红色,耐干摩擦色牢度为4~5级,耐湿摩擦色牢度为3~4级。Direct dyeing and mordant dyeings are carried out to dye silk fabrics with natural colorants extracted from peristrophe roxburghian.The effects of mordant dyeing conditions on the K/S value and rubbing fastness of the fabric are analyzed.The results show that the best method is post mordant dyeing.The optimized process is ferrous sulfate 4%(omf)or copper sulfate/aluminium potassium sulfate 3%(omf),dyeing at 45℃for 45 min.The dyed silk fabric has a high K/S value,the color is brownish red,color fastness to dry rubbing and wet rubbing are Grades 4-5 and 3-4 respectively.
