The fact that dyes in solution in the dye bath leave the bath and are sobned by the fibre/yarn material during the dyeing process has been of interest to chemist and physicists for many years. Theories of dyeing the describe the Sorption (or desorption) process and the resulting dye-fiber bonds using the tools of thermodynamics have increased in complexity over the year. Further more, it must be recognised that the dyeing process in dynamic in nature. It normally entails changes in the dyeing temperature the dye concentration the bath composition and the fiber structure.

Affinity and diffusion are fundamental aspect of the dyeing process. The former describes the force by which the dye is attracted by the fiber and the latter describes the speed with which it travels within the fiber/yarn a from areas of higher concentration to areas of lower concentration. Alone or together with fiber characteristics, affinity and diffusion determine the speed of dyeing, its temperature dependency, the equilibrium exhaustion of the dye, and some of its fastness properties.
