PURPOSE: To provide a cellulose shaped article having flexibility by forcing a cellulose amine oxide solution through a nozzle or through a gap, subsequently conducting it under a specific condition and coagulating and stretching the shaped article. CONSTITUTION: When a cellulose amine oxide solution is forced through a nozzle or through a gap, subsequently conducted through an air gap and finally coagulated in a coagulation bath, the ratio of marching-off velocity to hole exit velocity is at most 1 and the cellulose shaped article is stretched or deep drawn only after coagulation to obtain the objective cellulose shaped article. |
