Abstract
Results are given for the absorption of three disperse dyes by secondary cellulose acetate from solutions n benzene at 25° C. and 35° C. Additional results are given on the absorption of one of the dyes from solutions in methanol, butyl acetate, and carbon tetrachloride at 25° C. Formally the isotherms can be well represented by Langmuir's equation. The results obtained using different solvents show that, in general, the solvents do not act as inert transfer media but effect the basic absorption process for the dye. It is shown that the results can be explained if it is assumed that some solvents compete with the dye for absorption sites within the fiber.Keywords
