Abstract (en)

[origin: US5863478A] PCT No. PCT/AT97/00041 Sec. 371 Date Oct. 30, 1997 Sec. 102(e) Date Oct. 30, 1997 PCT Filed Mar. 3, 1997 PCT Pub. No. WO97/33020 PCT Pub. Date Sep. 12, 1997The invention is concerned with a process for the production of cellulose fibers wherein a solution of cellulose in a tertiary amine-oxide is extruded through spinning holes of a spinneret, whereby filaments are extruded, the extruded filaments are conducted across an air gap, a precipitation bath and a drawing device whereby the filaments are drawn, the drawn filaments are further processed into cellulose fibers, the drawn filaments being exposed during further processing to a tensile stress in longitudinal direction not exceeding 5.5 cN/tex.
