A process is disclosed for producing a cellulose shaped body by the aminoxide process. A suspension of cellulose in an aqueous tertiary aminoxide is transformed into a spinnable solution, is extruded through a spinneret and the thus obtained shaped body passes through a spinning bath. The process has the following characteristics: (a) a suspension is used containing a substance capable of reacting with cellulose and of contributing functional groups that are more nucleophilic than the cellulose hydroxy groups; and/or (b) a cellulose is used that bears functional groups that are more nucleophilic than the cellulose hydroxy groups; and/or (c) a suspension is used containing a polymer that bears functional groups that are more nucleophilic than the cellulose hydroxy groups; and/or (d) a substance is added to the spinnable solution that can react with cellulose and contribute functional groups that are more nucleophilic than the cellulose hydroxy groups; and/or (e) a polymer is added to the spinnable solution that bears functional groups that are more nucleophilic than the cellulose hydroxy groups.
