The tracer diffusion coefficients of three S35-labeled dyes in nylon 6 film have been determined. The diffusion coefficients show marked concentration dependence, but this takes a form different from that shown by chloride ions in a related study. It is not possible to explain the data on the basis
The dyeing kinetics of an acid dye (C.I. Acid Blue 40) in a nylon 6 film were investigated using partition-cell and film-roll methods at 80Β°C and pHs 2.3 and 3.05. The concentration dependence of diffusion coefficient of the dye in the nylon substrate measured by both methods was interpreted in term
