An anionic dye applied from an acidic or neutral dye bath. It has affinity for fibres containing basic groups
An anionic dye characterised by its substantivity (q.v.) for protein fibres and polyamide fibres and usually applied from an acidic or neutral dyebath.
Acid dyes are made for dyeing wool, silk and nylon and nothing does it better. If you have skeins of yarn or yards of fabric to dye, you've come to the right place. These powdered dyes are intended for vat-dyeing yardage, yarns or clothing. They can also be used for painting but they're not our first choice. If you intend to paint on silk or wool, choose one of the silk dyes from elsewhere in the catalog. You can use these dyes either on top of your stove or in a washing machine but they do require very hot water to work properly. The only other thing needed is a little white vinegar from your pantry. Acid dyes are very economical, as they react fast, they exhaust well and the results are Very Permanent- light and wash fast!
A dye which is applied to fabric or fiber from an acid dye solutions. It can be used on nylon, wool and other animal protein fibers, silk, acrylic, polypropylene and blends of the above. It is reasonably colorfast to light and laundering.
A class of dyes used on wool, other animal fibers, and some manufactured fibers. Acid dyes are seldom used on cotton or linen since this process requires a mordant.

Negatively charged coloring material used primarily on nylon carpet fibers. See Dyes.
