The copolymerizations of vinyl sulphone dyes with acrylonitile were carried out in the media of water and DMF, and in an emulsion system.

对乙烯砜型染料在较高浓度下与丙烯腈在沉淀、溶液、乳液等不同体系中的共聚反应进行了研究。

The mid-temperature vinyl sulphone reactive dyes are the most commonly used in most of domestic dyeing factories at present. Owing to three prime color dyes are the basis of match dyeing ,the stability of the three prime colors property determines the performance of the matched color ,so it is very important to select a team of low cost three prime color dyes with high light-perspiration fastness .

目前国内染厂大多数染色都采用中温型含乙烯砜活性基的染料，由于染料三原色是进行拼色染色的基础，三原色性能的稳定与否决定着拼出的色相的稳定性，选择一组具有较高耐光汗复合色牢度且拼色性能较好的低成本三原色具有重要意义。

In this dissertation , the fading status of several mid-temperature vinyl sulphone reactive dyes with different color and relatively low cost in light and perspiration has been tested according to the ATTS standard. A team of three prime color reactive dyes with high light-perspiration fastness (Levafix Fast Red CA、Reactive Yellow 3RS、Reactive Navy RGB) has been selected and the influence of different dyeing process parameter on their match performance were studied and finally the proper normal dyeing process was confirmed.
