Acid dyes are water-soluble anionic dyes that are applied to fibers such as silk, wool, nylon and modified acrylic fibers using neutral to acid dye baths.

Acrylic fibers are dyed with basic dyes, while nylon and protein fibers such as wool and silk are dyed with acid dyes, and polyester yarn is dyed with disperse dyes.
13.
Acid dyes set best with water near boiling, which won't damage the wool as long as you don't move it around vigorously, wring it out, or rub it.

16.
It now has become a general term to describe any histological staining method which uses two or more acid dyes in conjunction with a " polyacid " to differentially stain two basic materials in contrasting colours.

"' Acid Blue 25 "'( C 20 H 13 N 2 NaO 5 S ) is an acid dye that is water-soluble and anionic and used for adsorption researches.
18.
A second acid dye ( blue or green ) in dilute acetic acid is applied which, in turn, displaces the polyacid, resulting in collagen stained in a contrasting colour to the initial dye used.

Normally it would be expected that acid dyes would all stain the same basic proteins, but by applying them sequentially the staining pattern may be manipulated by removing dye from less intensely stained components with a " polyacid ", usually molybdophosphoric or tungstophosphoric acids.
