The Adsorption of Dye Mixtures by Cellophane Sheet. II. A Quantitative Discussion of the Adsorption of Dyes

Abstract 1. The single dyeings of Chlorazol Sky Blue FF and Chrysophenine G and the mixture dyeing of them were carried out at 50, 70 and 90°C. 2. In the single dyeing, the surface layer volume in Vickerstaff’s equation was adjusted so as to obtain constant values of the standard affinity. 3. In the mixture dyeing, the behavior of dyes was explained quantitatively on the basis of the information of the single dyeing and the interaction between both dyes in the dyebath.
