Zusammenfassung:A process for the production of a shaped cellulose body, comprises the steps of: ```- providing a solution of non-chemically derivatised cellulose, wherein said solution comprises at least one solvent for dissolving said cellulose and at least one processing aid for assisting the extrusion of said solution through an orifice; and ```- extruding said cellulose solution through said office. The solvent is preferably N-methylmorpholine N-oxide. The processing aid is preferably a second solvent that is miscible with N-methylmorpholine N-oxide, and may be selected from dimethyl sulfoxide, tetramethyl ammonium chloride or N-methylol caprolactam.
