Item PMX3KIT Includes: 2—1 lb/0.45 kg Soda Ash dye fixer Instruction Sheet/Color Chart 13—2/3 oz/18.71 g jars of Procion MX dye powder with the following colors: 010 Golden Yellow 011 Antique Gold 020 Brilliant Orange 030 Fire Engine Red 034 Magenta 040 Fuchsia 058 Marine Violet 068 Turquoise 072 Medium Blue 076 Cobalt Blue 094 Emerald Green 119 Chocolate Brown 150 Jet Black 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). Procion MX dyes are typically used with a soda ash fixative, which can be added directly to the dye bath or used to pretreat the fabric as in tie dyeing and other “batch setting” techniques.
