20090309256 | Method for stabilizing the spinning solution for production of cellulose composite molded bodies - The invention stabilizes spinning solutions used to produce cellulose composite molded bodies incorporating functional materials by the dry-wet extrusion method. The invention incorporates active materials detrimentally affecting the spinning process and materials which are unstable in the cellulose spinning solution, using separate active material and cellulose streams. The active material stream is produced, stabilized and stored separately and mixed with the cellulose stream directly before the forming apparatus, for example, a spinning bar. The active material stream includes amine oxide, functional materials, additives and water. The cellulose stream includes cellulose in amine oxide. The inventive method avoids heat build-up in the moulding or spinning solution, produces cellulose molded bodies with an adequately high degree of polymerisation and excellent functional properties and restricts the decomposition of the amine oxide. The interactions between cellulose and additive are restricted and storage life for the additive suspension improved. | 12-17-2009 |
