摘要(Abstract)：

为深入研究秦皮天然染料在染色加工中的应用,采用水浸提法从中药秦皮中提取天然染料对羊毛进行染色,通过测试染后样品K/S值对比了直接染色及不同媒染剂媒染染色工艺对染色效果的影响,并研究了染色温度及时间、染浴pH值、媒染剂硫酸铜用量、媒染温度及时间等后媒法染色工艺对羊毛染色效果的影响。结果表明:以硫酸铜作为媒染剂,采用后媒法染色工艺染色效果最好。秦皮天然染料对羊毛的最佳工艺为:后媒染染色工艺,染色温度100℃,染色时间45 min,染液pH值4.0,媒染剂硫酸铜用量2.0%(owf),媒染温度100℃,媒染时间30 min,染后样品K/S值及耐摩擦色牢度、耐皂洗色牢度显著提升。
