摘　　要：天然染料具有的环保性日益受到人们的青睐,但是大多数天然染料的染色性能不好,必须使用媒染剂才能提高上染率。媒染剂的种类很多,但大多数都是重金属,染色结束后染浴中残留的重金属离子排放到自然环境中,会对自然环境产生污染,这就违背了现在的环保理念。所以,开发新型环保媒染剂是扩大天然染料应用领域的重要途径。综述了近年来对媒染剂染色机理及新型环保型媒染剂的研究。Natural dyes have aroused more and more attention due to the environmental protection property. But for most natural dyes, the dyeing performance was very poor. And mordant should be used to improve the dyeing rate. There are many kinds of mordant, but most of them belong to heavy metals. So environment pollution may be caused by the residual emissions containing heavy mental ions, which goes against the latest green issues. Therefore, developing new type of mordant which is environmental friendly is an important way to expand the application field of natural dyes. Recent studies on the dyeing mechanism of mordant and new environment protection type of mordant were summarized.
