摘　　要：从红王子锦带花中提取天然染料并对其在柞蚕丝绸上的染色性能进行研究。测试了提取液的耐热及耐酸碱稳定性,优化了提取液对柞蚕丝绸染色的工艺。探讨了媒染剂和染色方法对织物染色效果的影响。分析比较了染色丝绸的颜色特性及染色牢度。结果表明:红王子锦带花染料具有良好的耐热稳定性,在酸性条件下具有稳定的颜色,红王子锦带花染料可直接染色织物,直接染色工艺条件为:染液质量浓度0.8A,温度70℃,时间60 min,pH=4.5,浴比1:30。媒染可提高染色织物的染色深度和色牢度,各项色牢度指标都符合国家标准。Natural dyes extracted from Weigela florida cv.Red Prince and on the silk fabrics dyeing proper- ties were studied. The heat-resisting, acid and alkaline stability of the extraction were tested, and the process of extract dyeing were optimized. The effect of mordant and dyeing methods for silk fabrics dyeing properties were discussed. The color characteristics and fastness of the dyed silk fabrics were analyzed and compared. The results showed that the Weigela florida cv.Red Prince dyeing has good heat-resisting, acid and alkaline stability. It has the stable color in the condition of acid. Weigela florida cv.Red Prince could be directly dyed fabric, the dyeing conditions included the solution mass concentration of 0.8A, dyeing temperature 70℃, dye- ing time 60 min, pH=4.5, bath ratio 1 ： 30. Mordant could improve the dyeing depth and the color fastness of dyed fabric, and the color fastness indicators accorded with the national standards.
