Acid dyeing

A fabric finish as anionic dye bonding to wool and silk protein—the acid dyeing process on textile finishing, distinct from [[disperse-dyeing|Disperse dyeing]] as related cousin and from [[direct-dyeing|Direct dyeing]] without acid dyeing naming.

How to recognize it

Acid dyeing shows acid dyeing as sulfonic acid dye attaching to protein fiber amine groups below pH 4.

Disperse dyeing is the related cousin finish. Direct dyeing names a different textile process.
