| Summary: | The ability of the channel flow cell to probe reactions at a solution/non-conducting solid interface makes it a powerful method for investigating dyeing reactions. The technique gives direct information about the surface concentrations of dye at the fibre surface and thus allows the elucidation of dyeing mechanisms and the determination of kinetic parameters. The experimental realisation of the channel flow cell in this context and its basic theory are outlined and the strength of the methodology illustrated with investigations of various reactive dyes and model acid dyes. These studies ailow a generalised model of dyeing phenomena to be proposed. |
