Wool and silk Acid Dye 639 Jet Black

Acid dyes are used to color silk, wool, feathers, other protein fibers and 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 during immersion dyeing. They exhaust well and won’t bleed or fade with washing. Of all the colorants in the world, acid dyes are known to produce the most luscious colors of all, and Jacquard’s palette is unsurpassed for quality, intensity and consistency.

In addition to yarn, fiber and fabric dyeing, Jacquard Acid Dyes may also be used for direct painting or printing applications, using steam setting.

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.
