活性染料的进展(二)——纪念国产活性染料诞生40周年

Progress of Reactive Dyes Developments (Ⅱ)

2.2 活性基不同的双活性基染料2.2.1 一氯均三嗪和乙烯砜复合含有乙烯砜和一氯均三嗪双活性基的活性染料,由于其性能优良,具有高固色率,优级染色牢度和良好的染色性能,是最有发展前途的活性染料.1980年日本住友开发了SumifixSupra染料,1984年德国赫司特开发了Rema-zol S型和SN型染料.嗣后,相继有上海染化八厂的ME型,上海万得化工有限公司的Megafix B型,德国BASF公司的Basilen FM型等染料.这些品种比国内开发的M型活性染料约晚十年,但其品种系列化及开发研究深度均领先于M型活性染料.它的结构通式为:

Reactive dyes have been developed greatly both at home and abroad for nearly fourty years. The present situation of reactive dyes development particular in new reactive radical and parent dyes, related to low salt and new a-gent-style reactive dyes are described in details.
