It is an ancient process, with evidence of dyed fabric dating back as far as the Neolithic era. The most basic method of dyeing involves simply dipping the material into a hot dye bath and allowing the fibers to absorb or bond with the dye until the desired color is reached. However, there are often steps performed beforehand to prepare the fiber to absorb the dye such as scouring, bleaching, and mordanting.
