Notes:
The physical model of the reactive dyeing system proposed by Sada et al. is extended in this communication to the case with a conentration-dependent diffusion coefficient of dye. The present model with an exponential concentration dependence of the diffusion coefficient is shown to predict the observed data better than did the previous one with a constant diffusion coefficient. Effects of the concentration dependence of the diffusion coefficient, dye reaction rate, degree of mixing, and volume ratio of fiber substrate to the dyebath on the rate of fractional fiber fixation and the dye concentration in the dyebath are investigated parametrically. It has been found that the effect of the volume ratio of the fiber substrate to the dyebath on the fractional fiber fixation is not of the same order of magnitude as those of the other three factors.
