A clearer appreciation of the significance of the conventional standard affinity of dyeing (–μo)can be obtained if the nature of the driving forces behind dyeing in simple, model dyeing systems is analysed. It is then seen that the standard affinity of dyeing is the driving force behind dyeing in a particularly well–defined model of the dyeing system, at a particular stage of dyeing. The simple assumption that the rate of dyeing is directly proportional to the magnitude of the driving force behind dyeing provides a unifying link between the thermodynamics and the kinetics of dyeing and is consistent with modern theories of nonequilibrium thermodynamics. The extension of these ideas to an analysis of the nature of the driving forces in systems in which the rate of dyeing is determined by diffusion processes within the fibre produces a rather surprising result that reveals the true complexity of the concept of ‘affinity’ in dyeing.
