| titleOfInvention | PROCESS FOR THE MANUFACTURE OF YARNS OR FILMS |
| abstract | Process for the manufacture of yarns or films of regenerated cellulose, where the cellulose is dissolved in a solvent mixture of dimethylsulfoxide and formaldehyde, preferably paraformaldehyde, and the solution treated with a regenerating medium, characterized in that the finely divided cellulose, with a DP polymerization rate of 230 to 400 is mixed, preferably kneaded, with the solvent at a temperature of 120 to 150 degrees C, optionally under the simultaneous action of ultrasound, which makes it possible to obtain clear solutions of a content of 20 to 10% by weight of cellulose, after which these solutions are spun in an aqueous spinning bath or precipitated in an aqueous precipitating bath, then stretched and optionally reprocessed with an aqueous washing agent. |
