Acid Dyes

USE FOR: Immersion (tub) dyeing and direct application techniques when followed by steaming for colour fixation.

USE ON: Protein fibers such as wool and silk, as well as hair (fur), feathers, and nylon. Some shades may also be used on leather, particularly pre-metalized colours.


Dyer Depot acid dyes are concentrated powdered dyes formulated for use on protein fibers and nylon. They are economical, easy to measure, and designed to deliver reliable, repeatable results when used with proper heat and acidity.

These dyes can be used in many creative approaches, including solid immersion dyeing, low-water methods, microwaving, baking, printing, spraying, painting, and steaming. Different fibers, heat levels, and application methods will produce different effects, making sampling an important part of the process.

Colour results may vary between different materials, and appearance can differ across screens and lighting conditions. When accuracy matters, testing is strongly recommended. For results closest to our colour charts, most shades perform well at 1.5–2% on weight of goods (OWG) for immersion dyeing. Colours marked with an asterisk (*) are best used at 4% OWG. Adjust usage to achieve the depth of shade you prefer. Finished items dyed with acid dyes should be washed in cold water.

Citric Acid

$6.00

Citric acid is used as an acidifier when dyeing protein fibers such as wool, alpaca, silk, and other animal fibers with acid dyes. It lowers the pH of the dye bath, helping the dye bond with the fiber for effective color fixation and good washfastness.

Easy to measure and dissolve in water. Suitable for hand-dyeing and professional dyeing applications.
