PHYSICAL CHEMISTRY APPROACH TO DYEING THEORY
Dyeing is concerned with colored organic compounds which are soluble in appropriate solvents and which can become absorbed on to molecular surfaces of textile substrates in a controllable manner, and of diffusing within these substrates. Consequently, the physical chemistry of dyeing covers aspects of the nature of solutions of complex molecules, adsorption and related interfacial phenomena, and diffusion. Further, it is often convenient to treat dyeing systems as being in a state of equilibrium, so thermodynamics is an important tool.
KINETIC APPROACH TO VS REACTIVE DYEING
Reactive dyes have become one of the most typical and conventional coloring matters for cellulose, since they have good color-fastness, bright hues, and good cost performance. They are classified into two categories, i.e., dye nucleus with halogeno-heteroaromatics or sulfatoethylsulfonyl(sodium salt, SES) reactive end-groups, in which the latter one is called vinyl sulfonyl(VS) dye and has large market.. This research aims to clarify the following problems; a) the reaction mechanism of hydrolysis of VS reactive dyes. b) the quantitative reaction with cellulose.
