DYEING OF TEXTILE ASSEMBLY BY LIQUOR FLOW UNDER INFINITE BATH CONDITION

Abstract

The formulation of sample distribution in column-chromatography, which was given in our previous paper, has been extended to a model dyeing of textile assembly by liquor flow. The equation derived for the dyeing from infinite bath was in general agreement with the observation on the dyeing practice of polyamide-powder column. From the theoretical and the practical distribution profiles obtained under several conditions we could conclude that “level dyeing” is attained rapidly by the rapid flow or by the low affinity of dye to substrate.
The most interesting result was that the distribution profile of dye in the column depended not only on the flow rate and the affinity, but also on the particle size (corresponding fiber diameter).
