Procion MX dyes are cold water dyes that are fixed chemically instead of with heat. This unique property sets them as the undisputed king of backyard dyeing, batik and tie dye. They are also the ideal colors 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 tap water to create the most vibrant colors possible for cotton, linen and other plant-based fabrics (may also be used with protein fibers if acidified). Available in a variety of colors, each sold separately. This package contains Jacquard Procion MX Dye 8oz. Made in the USA.
