Reverse tie-dyeing is a form of discharge dyeing, which is when chemicals are used to remove existing dye from a piece of fabric. Sodium hypochlorite, or common household bleach, is the chemical of choice that is used with reverse tie-dyeing. Reverse tie-dyeing with bleach works best on cellulose fabrics, such as cotton or linen. Bleach should not be used on polyester, spandex, wool, silk, or other synthetic or animal-based fibers.
