A study of available knowledge on the application of dyes to woven fabrics on the jigger has led to the formulation of a model– ‘the ideal system’– which can be used to yield predictions in close agreement with observation. The model is based on new experimental and theoretical work, and the assumptions made can be justified. The most important conclusion is that the normal jigger process, to which most successful dyeings conform, is independent of the rates of dyeing of the dyes used. The course of dye absorption can be characterised by a single parameter, the exhaustion exponent (A), which is defined in terms of experimentally determinable jigger and fabric quantities.
