Abstract
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.
