- STUDY ON ADSORPTION OF MONOBASIC DYES ON THREE KINDS OF NYLON 6 FIBERS HAVING DIFFERENT AMINO GROUP CONTENTS
抄録
The adsorption isotherms of nine monobasic dyes on three kinds of Nylon fibers at constant pH (4.0) have been determined at 90°C. The Nylon fibers, Nylon-1, -2 and -3 had amino group analyses of 25, 54 and 95meq/kg, respectively. From the adsorption isotherms the saturation values of the dyes on each Nylon are calculated. For the dyes of high affinity, these values were found to be approximately equal to the amino group content. For the dyes of low affinity, however, the saturated values reduced, and the deviation from the stoichiometric uptake increased with a decrease in the affinity of the dye. The deviation was explained by assuming the presence of, (1) the electrical repulsion between carboxylate anion of Nylon and dye anion (2) the change in the affinity of dye with variations of the orientation of amorphous region.
