Dyeing refers to the process in which a dye is transferred from the dyeing solution to the fiber and forms a uniform, firm and bright color on the fiber. The chemical composition of various fibers is different, and the applicable dyes are also different. The commonly used dyeing methods include high temperature method, carrier method and hot-melt method.

If there are multiple fibers in a fabric, the dyes and temperatures required for coloring these fibers are different, which can be completed by one-time dyeing.
