Abstract

The dye bath consists of water-free, liq. NH3 in which the dye is dissolved. Suitable dyes include direct, dispersion, naphthol, reactive and sulphur dyes, and a wide range of synthetic and natural fibres and films may be dyed. Dyeing times are much reduced (20 secs.) and deep shades are obtd. on some fibres e.g. cellulose triacetate with dyes e.g. direct and reactive dyes, which are unsuitable for use in usual aq. dye baths.
