REACTIVE DYES CONTAINING(N-METHYL-β-SULFOETHYLAMINO)ETHYLSULFONYL GROUPS FOR SILK FIBRES 总被引:1,自引:0,他引:1
Silk dyeing with several classes of reactive dyes was studied.A class of reactive dyes con-taining(N-methyl-β-sulfoethylamino)ethylsulfonyl groups for silk is presented.A new method forintroducing such a reactive group and a kinetic studies on the reaction mechanism involved are pro-posed.A kinetic isotopic effect on dyeing mechanism with silk is discussed and the optimum dyeingtechniques recommended.Dyeing or printing was carried out in neutral media;brilliant shades,goodfastness,high fixation and excellent storage stability are given. 相似文献
