| description | The present invention is directed towards a method for spinning neutral or anionically modified cellulose comprising the steps of: (a) preparing a suspension of the neutral or anionically modified cellulose in a continuous phase; (b) subjecting the suspension to high shear rate; (c) performing spinning by extruding the cellulose suspension into an airgap region comprising at least one heated zone to obtain spun fibers, (d) subjecting the spun fibers to at least one washing stages and (e) isolating the spun fibers from the at least one washing stages; as well as fibers obtained based on the method of the invention and paper or board products derived from such fibers. |
