Application and Dyeing Process of Substantive Dye

This paper reports the studies available on the theory of substantive dye, the application properties of substantive dye and dye ability of fibers in relation to dye structure. Dyeing with substantive dyes and comparison with acid dyes; some properties of aqueous solutions of the substantive dyes; adsorption of substantive dyes from aqueous solution; distribution of a colloid between an interface and the distribution medium was discussed. The interaction between dye and fibre under given dyeing conditions was presented. Different researchers studied the process of dyeing with substantive or colloidal dyes and the factors which affect the dispersion and stability of the dye.
