多活性基活性染料进展

Progress in reactive dyes with multi-reactive groups

同一染料母体上引入多个活性基团是提高活性染料固色率及改进染深性的有效方法,近年国外不断开发该类染料新品种,使之应用性能更加完善。目前,活性染料向染色型发展,而且以竭染法为主。多活性基活性染料最适于竭染法染色。因此,该类染料的发展有着广阔的前景。

An effective way to enhance the fixation rate of reactive dyes and improve the depth of dyeing is to introduce multi-reactive groups into the dye molecule. In recent years new products of reactive dyes have been vigorously developed with an aim to perfect their application characteristics. At present the development of reactive dyes of dyeing type, particularly the exhausting dyeing is the main trend of development of reactive dyes and reactive dyes with multi-groups are most suitable to exhausting dyeing. Therefore this kind of dyes has bright prospects.
