Zusammenfassung:The effect of inorganic salts on the melting point and viscosity of a carbamide melt and its solvating power with respect to disperse dyes and polyester fibre was investigated. The high effectiveness of the carbamide--LiCl and carbamide--CaCl systems in fixation of disperse dyes on polyester fibre was established. A probable mechanism is proposed for the activating effect of inorganic salts on fixation of disperse anthraquinone dyes on polyester fibre in the presence of carbamide.[PUBLICATION ABSTRACT]
