Beschreibung
Zusammenfassung:	A manufacturing process for acrylic fibres with noncircular cross-section is disclosed. The acrylic fibres are prepared by extruding the solution containing acrylic polymer and sodium thiocyanate through circular orifices and coagulating the extruded fibres in a coagulation bath containing a coagulating agent. L'invention concerne un processus de fabrication pour fibres acryliques dotées d'une section transversale non circulaire. Les fibres acryliques sont préparées par extrusion de la solution contenant du polymère acrylique et du thiocyanate de sodium à travers des orifices circulaires et coagulation des fibres extrudées dans un bain de coagulation contenant un agent coagulant.
