The object of this paper is studied to the possibility of extracting colourants from carthani flos and coptidis thizoma 研究发现两种天然染料对羊毛以酸性媒染染法染色最具染色性，且因不同的媒染剂的结合而有不同的色相及坚牢度。

The results showed that the directly dyed samples had rate 3 ~ 4 rubbing and soaping color fastnesses , and the iron mordant dyed ones had rate 4 rubbing and soaping fastnesses 试验结果表明：直接染色样品的摩擦色牢度3 ~ 4级，皂洗色牢度3 ~ 4级，铁媒染后摩擦色牢度和皂洗色牢度提高为4级。

To solve the problem of adverse influence on the environment exerted by the residue dye liquid from traditional dyeing of wool with acid mordant dyes by after - chroming , and to lessen the pressure of chromium - containing waste water treatment , the dyeing method was modified by adopting two - bath dyeing technique in which the initial dyeing liquid and mordant dyeing liquid could be used in the recycled way , thus saving dyestuff and reducing the drainage of chromium - containing waste water 摘要为解决传统羊毛酸性媒介染料后媒法染色残液对环境的影响，减轻含铬废水处理压力，采用二浴循环染色技术对传统羊毛酸性媒介染料后媒浴染色法进行改进，改进后的染色新工艺可以做到初染液及媒染液循环使用，节约了染料，并降低了含铬废水的排放。
