Process for preparing a cellulose molding article according to the amine oxide process, whereby a suspension of cellulose in an aqueous tertiary amine oxide is transferred into a spinnable solution, extruded through a spinning nozzle and the molded article is passed through a precipitation bath. Procedure (a) uses a suspension containing a substance that reacts with the cellulose and which can introduce functional groups that are more nucleophilic than the hydroxy groups in the cellulose, and / or (b) a cellulose is used. containing functional groups that are more nucleophilic than the hydroxy groups in the cellulose, and / or (c) a suspension containing a polymer having functional groups that are more nucleophilic to the uydiruksyg Loups in the cellulose is used, and / or (d) it is added to the spinnable solution is a substance that reacts with the cellulose and which can introduce functional groups, the groups being more nucleophilic than the hydroxy groups in the cellulose, and / or (e) adding to the spinnable solution a polymer containing functional groups which are more nucleophilic than the hydroxy groups in the cellulose. |
