Acid dyes are highly effective, vibrant, and water-soluble colorants specifically designed to bond with (wool, silk, alpaca, mohair, cashmere) and nylon in a mildly acidic environment. They are known for exceptional colorfastness and producing deep, brilliant shades. Despite the name, the "acid" refers only to the necessary addition of white vinegar or citric acid to the dye bath, not the dye itself. Essential Supplies Protein Fibers: Wool or silk yarn/fabric. acid dye
Acid dyes are anionic (negatively charged) and, when added to hot, acidic water, form a strong ionic bond with the cationic (positively charged) amino groups in protein fibers.
Acid dyes "exhaust" exceptionally well, meaning nearly 96-100% of the dye moves from the water to the fiber, making them environmentally friendly with little chemical residue. Heat Set: Heat is crucial for fixing the dye to the fiber. Basic Immersion Dyeing Technique Do not use dyeing pots or utensils for food preparation
Always use a respirator when handling dry dye powder to avoid inhaling fine particles.
Stainless steel or enamel pot (non-food-safe), measuring spoons, scale, and stirring utensils. How Acid Dye Works Working with wool or nylon
Add the wet fiber to the pot before the dye is at full temperature to ensure an even, level color.
