ABSTRACT:
An optically anisotropic solution containing cellulose and inorganic acids of phosphorus contains 94-100 wt % of the following constituents: cellulose; phosphoric acid and/or its anhydrides; and water; and 0-6 wt % of other constituents. This solution can be prepared in an apparatus in which intensive mixing is made possible by the shearing forces generated by mixers and kneaders in the apparatus. The solution can be used in making pulp, hollow fibres, staple fibre, membranes, nonwovens, or films.
