Zw. Wu et al., REACTIVE DYES CONTAINING (N-METHYL-BETA-SULFOETHYLAMINO) ETHYLSULFONYL GROUPS FOR SILK FIBERS, CHINESE JOURNAL OF CHEMICAL ENGINEERING, 4(1), 1996, pp. 1-10
Silk dyeing with several classes of reactive dyes was studied. A class
of reactive dyes containing (N-methyl-beta-sulfoethylamino) ethylsulf
onyl groups for silk is presented. A new method for introducing such a
reactive group and a kinetic studies on the reaction mechanism involv
ed are pro, posed. A kinetic isotopic effect on dyeing mechanism with
silk is discussed and the optimum dyeing techniques recommended. Dyein
g or printing was carried out in neutral media; brilliant shades, good
fastness, high fixation and excellent storage stability are given.
