| titleOfInvention | Method for the production of cellulosic flat films |
| abstract | A method for the production of cellulosic flat films, comprising the steps of - shaping a solution of cellulose in an aqueous tertiary amine oxide into the form of a film by means of an extrusion die with an elongated extrusion gap - transporting the shaped solution via an air gap into a precipitation bath, whereupon the cellulosic flat film is formed in said precipitation bath, - stretching the cellulosic flat film in the transversal direction after having entered the precipitation bath, - washing the cellulosic flat film and - drying the cellulosic flat film. The method is characterized in that stretching in the transversal direction is performed in two steps, wherein in the first step the flat film is stretched to a stretching degree being higher than the stretching degree finally desired, and in the second step the flat film is allowed to relax to the stretching degree finally desired. |
