Traditional acid dyes refer to water-soluble dyes containing acidic groups in the dye structure, which are usually dyed under acidic conditions. The acidic groups in acid dyes are generally sulfonic acid groups (-SO3H), which exist on the dye molecules in the form of sodium sulfonate (-SO3Na). Some dyes also use sodium carboxylate (-COONa) as acid Group.
