Fiber Reactive Dye/Procion MX Dyes (dichlorotriazine):
Fiber reactive dyes are used to dye plant based/cellulose fibers (cotton, linen, canvas, hemp, jute, ramie, sisal, paper, rayon etc) in cold water (75F-95F). Addition of salt and dye activator (soda ash, washing soda, Sodium Carbonate, Na2CO3) are necessary. Techniques that can be used with these dyes: tie dye, immersion dyeing, batik, screen printing, direct application, gradation/ombré dyeing, sprinkle dyeing. Instructions for techniques other than full immersion can be found in Jacquard’s Procion MX Dye – Instructions. Scour fabric prior to dyeing following these instructions. Natalya can scour muslin and canvas in large quantities, if asked ahead of time. WEAR N95 MASKS WHEN MEASURING OUT DYE POWDER. IMMEDIATELY CLEAN UP ANY DYE POWDER SPILLS. For full immersion dyeing, use:

Pure colors/single hue dyes are available under different names from retailers. Retailers and manufacturers mix these single hue dyes to produce proprietary color mixes.
