Abstract

In the preparation of viscose, the caustic alkali solution is cooled to a temperature not exceeding 5 DEG C., for example to 2 DEG C. before addition to the cellulose material. To assist the penetration of the caustic alkali solution into the cellulose, the air in the vessel in which the treatment is carried out may be evacuated or may be replaced by a gas that is soluble in or reacts chemically with alkali solution, such as ammonia gas or sulphur dioxide.
