Dyeing process are value-added treatments for most textile materials. A dyeing process is the interaction between a dye and a fibre, which involves adsorption (transfer of dyes from the aqueous solution onto the fibre surface) and diffusion (dyes diffused into the fibre).
In the dyeing process, various dyeing auxiliary agents such as levelling agents for level dyeing, soaping agents for washing off unfixed dyes for improving dye fastness, fixing agents for fixing dyes to fibers or fabric are used.
