Aluminum acetate is a purified mordant powder that creates bright colors on plant fibers. It is an alternative mordant to traditional tannins. Mordanting is an important step in natural dyeing as it helps improve light and washfastness. Its purpose is to provide a bond between the fiber and the dye molecule. Without a mordant bond, natural dye colors will fade, change color and wash out.
