Soda Ash dye fixer is a mild alkali that promotes the chemical reaction between Procion MX fiber reactive dyes and cellulose fiber. It is also known as sodium carbonate, washing soda or sal soda. Soda Ash is necessary to activate and set Procion MX dye, which, when added to water, produces exceptionally brilliant color ideal for all natural materials such as cotton, rayon, linen, silk, wool, paper, reeds and wood. This fixer allows you to experiment with a variety of applications including tie-dyeing, vat dyeing, batik, airbrush, hand painting, printing and spatter painting.
