Jacquard Procion MX fiber reactive dye is a cold water concentrated powdered dye which produces exceptionally brilliant color. The dyes are intermixable, and the resulting colors are permanent, colorfast and completely washable. It is ideal for a variety of applications including tie-dyeing, vat dyeing, batik, airbrush, hand painting, printing and spatter painting. Procion MX will dye all cellulose (plant) fibers, such as cotton, linen, jute, rayon, sisal and paper. It can also be used to dye some protein (animal) fibers, such as wool and silk. Generally, one 2/3 oz. jar can dye more than five yards of fabric – about nine T-shirts.
