Acid dyes (the ‘acid’ is white vinegar or citric acid) are used to colour silk and wool and other protein fibers (as well as some nylons), and nothing does it better! Extremely brilliant and colourfast, Jacquard Acid Dyes are highly concentrated, powdered hot water dyes that produce level, uniform colour when immersion dyeing. They exhaust extremely well and won’t bleed or fade with washing. Of all the colourants in the world, acid dyes are known to produce the most vibrant colours of all, and Jacquard’s palette is unsurpassed both for quality and intensity. Use on protein fibers such as silk, wool, cashmere, alpaca, feathers, etc. and some nylons. 1/2oz / 14.17gm Bottles
