METHOD OF MANUFACTURING MOLDED CELLULOSE PRODUCTS Russian patent published in 2004 - IPC

Abstract RU 2221091 C2

FIELD: cellulose materials. SUBSTANCE: molded cellulose products such as fibers and filaments are prepared by dissolving cellulose in aqueous solution of N- methylmorpholine oxide and extruding cellulose solution using molding tool through air slot into spinning bath to coagulate extruded products. Cellulose solution and/or spinning bath solution contain surfactant in concentration between 5 and 100 ppm and width of slot ranges from 2 to 20 mm. EFFECT: prevented deterioration or great fluctuations in textile-physic properties of molded fibers and filaments when width of slot is narrowed. 12 cl, 1 tbl, 6 ex
