Acid dye - Wikipedia
Acidic dyes can be classified according to their dyeing behavior. This includes their wet fastness, migration ability, and dyeing pH: Leveling acid dyes: These dyes have relatively low molecular weights. Consequently, they migrate more readily before fixation and they exhibit low wet fastness. They are not normally suited for use as apparel fabric. They require an a… See more
- Dyes can be classified by their substantivity, which depends, in part, on the nature of the substituents in the dye molecule. Attractive ionic interactions are operative in the case of anionic (acid) and cationic (basic) dyes, which have negatively and positively charged groups, respectively.www.britannica.com/technology/dye/General-features-of-dyes-and-dyeing
