含金属毛用染料的生态问题和取代品

Ecological Problems of Metal-Contained Dyestuffs Used for Wool and Substitutes

含金属毛用染料是提高毛织物附加价值的重要化学品。本文阐述了含金属毛用染料特别是铬媒染料的生态问题：染色排出液中的铬污染问题、毛织物上铬污架问题，无使用价值的染织物的铬污染问题，并把新型毛用活性染料与铬媒染料的性能进行比较，指出新型毛用活性染料是铬媒染料的最佳取代品之一。

The metal-contained dyestuffs used for wool were an important chemicals to raise the additive value of the wool fabrics.The ecological problems of the metal-contained dyestuffs used for wool,especially the chrome dyestuff, were described in this article that is,the pollution problem of chromium discharged in the effluent,the pollution problem of extractable chromium to be present on the garments,a concern from the pollution aspect of disposal of such products at the end of the useful life of the garments. Also,the properties of the new type of reactive dyestuff used for wool were compared with the properties of the chrome dyestuff It Was Pointed out that the new type of reactive dyestuff was one of the best substitutes of the chrome dyestuff.
