To add color by a process to textile products such as fibers, yarns or fabrics is called Dyeing. Normally dyeing is done on a special solution containing dyes and particular chemical material. Dye liquor is defined as, the process of coloring textile materials with dyes in an aqueous solution. Dyeing is done by the interaction between fiber, water and chemicals material.

Sequence of Dyeing Process: The sequence of dyeing process is given below,

            Dye dispersed in a dye bath

                                    ↓ Diffusion

            Dye in the diffusion layer

                                    ↓ Molecular diffusion

            Dye in the electrical double layer

                                    ↓Absorption

            Dye absorbed in the fiber surface

                                    ↓ Sorption

            Dye diffused in the fiber

                                    ↓ Fixation

            Dye physically/chemically bonded with the fiber
