Textile threads containing basic groups are prepared - form acetic acid containing solutions of anionic dyestuffs

摘要

Composition is made from solutions of anionic dyestuffs in homogeneous mixtures containing acetic acid and an aliphatic hydrocarbon or aliphatic halogenated hydrocarbon derivative, or a mixture of both. Specifically it may contain an alcohol or a phenol. It may involve the formation of an acetate from the alcohol and acetic acid. Fibres may be dyed by a known immersion process, Fullers Earth treatment or pulverisation at 10-50 degrees C.
