Beschreibung
Zusammenfassung:	The present invention is directed towards a method for spinning anionically modified cellulose comprising the steps of: (a) preparing a suspension of the anionically modified cellulose in a continuous phase; (b) subjecting the suspension to high shear rate; (c) performing spinning by extruding the cellulose suspension through a spinneret into a spin bath comprising a cationic complexing agent, and (d) isolating the spun fibres from the spin bath; as well as fibres obtained based on the method of the invention and paper or board products derived from such fibres. La présente invention concerne un procédé de filage de cellulose modifiée au plan anionique comprenant les étapes de : (a) préparation d'une suspension de cellulose modifiée au plan anionique dans une phase continue ; (b) soumission de la suspension à un taux de cisaillement élevé ; (c) mise en uvre du filage par extrusion de la suspension de cellulose par une filière dans un bain de filage comprenant un agent complexant cationique, et (d) isolement des fibres filées du bain de filage ; ainsi que des fibres obtenues par le procédé de l'invention et des produits de papier ou de carton dérivés de ces fibres.
