Removal of Dyes
If things go wrong in the dyeing process, the dyer may be forced to remove the dye already applied by a process called "stripping". This normally means destroying the dye with powerful reducing agents such as sodium hydrosulphite or oxidizing agents such as hydrogen peroxide or sodium hypochlorite. The process often risks damaging the substrate (fiber). Where possible, it is often less risky to dye the material a darker shade, with black often being the easiest or last option.
