摘要

New polymer solutions, processes for producing such solutions, shaped articles made from these solutions, and process of making such articles, are disclosed. The polymer solutions contain cellulose having a degree of polymerization of at least 200, an acrylonitrile polymer, dimethylsulphoxide and formaldehyde. The weight ratio of cellulose/acrylonitrile polymer is 0.05 to 1, preferably 0.1 to 1, the weight ratio of formaldehyde/cellulose is 0.2 to 2, and the total concentration of polymer in the solution is 12 to 30% by weight, preferably 18 to 26% by weight. The solutions of the present invention are particularly suitable for the production of filaments consisting of fibrils orientated approximately along the axis of the fibre and closely interwoven, with the cellulose macromolecules being partially involved in a crystal lattice characteristics of cellulose II. The filaments possess valuable properties for use in textiles, such as, for instance, in garments.
