Notes:
The processes of adsorptive and reactive dyeings of polymer film in a finite bath were formulated on the basis of pore model concept. The influence of the bath ratio on the fractional uptake or fixation was numerically analyzed. The time of half-dyeing is proportional to the bath ratio to the power of about 0.9 within the present computational conditions. This fact is in contrast to the finding that, in an infinite bath with the same dye concentration as the initial value in a finite bath, the time of half-dyeing is inversely proportional to the dye concentration. The relation of the total uptake or fixation to the dimensionless dyeing time θ multiplied by γ0.9 is independent of the bath ratio within an error of 5% or 8%.
