METHOD OF PRODUCTION OF THE FINE FILAMENT CELLULOSE THREAD Russian patent published in 2006 - IPC D01D5/06 

FIELD: chemical industry; medicine; methods of production of the fine filament chemical threads.

SUBSTANCE: the invention is dealt with chemical industry and medicine, in particular, with the method of production of the fine filament cellulose thread with the superfine filaments and may be used in production of filter materials for filtration of the blood and its components. The method of production of the fine filament cellulose thread is characterized according to the invention by the fact, that the molding process is realized at the outflow of the spinning solution with the speed of 10.5 - 11.5 m/minute and with the drawdown of 40-70 % with production of the superfine filaments of the linear density less than 0.05 tack. The plasticization drawdown makes 70-90 %. The filament washdown is conducted in four stages using the soft water. The filament is subjected to spinning of 40-50 rounds per a minute. The technical result of the invention is production of the cellulose threads out of the superfine filaments of the linear density less than 0.05 tack.

EFFECT: the invention ensures production of the cellulose threads out of the superfine filaments of the linear density.
