ABSTRACT:
The present invention relates to new polymer solutions which make it possible to produce shaped articles, such as yarns and fibres, films, sheets and the like.
These solutions consist of cellulose having a degree of polymerisation of at least 200, polyamide-imide, dimethyl sulphoxide and formaldehyde, with a weight ratio cellulose/polyamide-imide of 0.05 to 1, preferably 0.1 to 1, a ratio formaldehyde/cellulose of 0.2 to 2 and a total concentration of 6 to 25%, preferably 15 to 20%.
These solutions are particularly suitable for the production of filaments which consist of fibrils substantially orientated along the axis of the fibre and closely intersecting, the cellulose macromolecules being partially involved in a crystal lattice characteristic of cellulose II. The filaments possess valuable properties for use in textiles.
