APPLICATIONS
|
|
Acid dyes are water-soluble dyes employed mostly in the form of sodium salts of
the sulfonic or carboxylic acids. They are anionic which attach strongly to
cationic groups
in the fibre directly. They can be applicable to all kind of natural fibres like
wool, cotton and silk as well as to synthetics like polyesters, acrylic and
rayon. But they are not substantive to cellulosic fibres. They are also used in
paints, inks, plastics and leather.
