Procion MX dyes are “cold water dyes” that do not require heat. This unique property sets Procion MX apart from all other dyes and establishes them as the undisputed king of backyard dyeing, batik and tie dye. Because Procion MX dyes can be used away from the stovetop, they are also perfect for shibori, ice dyeing, tub and low water immersion dyeing, printing, direct painting and other alternative” dye applications. As a fiber reactive dye, Procion MX forms a strong covalent bond with cellulosic fibers, making it the most permanent and washfast of all dyestuffs. Mix the concentrated dye powder with warm tap water to create the most vibrant of all colours for cotton, linen and other plant-based fabrics. Procion MX dyes are typically used with a soda ash fixative, which can be added directly to the dye bath or used to pre-treat the fabric, as in tie dyeing. Typically, one 2/3 oz/18.71 g bottle will dye more than 1 lb/0.45 kg of dry fabric. (Very bright colours will require more dye and pastel colours will require less.)
