Jacquard Procion Dyes and Acid Dyes

Jacquard Procion Dyes, cold water dye for natural fibers

"Procion MX dyes are “cold water dyes” that are fixed chemically instead of with 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 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). 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. Typically, one 2/3 oz/18.71 g bottle will dye more than 1 lb/0.45 kg of dry fabric (very bright colors will require more dye and pastel colors will require less)."

Jacquard Acid Dyes

"Acid dyes are used to color silk and wool and other protein fibers (as well as some nylons), and nothing
does it better! Extremely brilliant and colorfast, Jacquard Acid Dyes are highly concentrated, powdered
hot water dyes that produce level, uniform color when immersion dyeing. They exhaust extremely well
and won't bleed or fade with washing. Of all the colorants in the world, acid dyes are known to produce
the most vibrant colors of all, and Jacquard's palette is unsurpassed both for quality and intensity."

"Don't be alarmed by the name-the only acid involved is the white vinegar or citric acid that you add to the
dye bath."

"In addition to yarn, fiber and fabric dyeing, Jacquard Acid Dyes may also be used for direct painting."
