摘要： The invention relates to a method for producing cellulose flat sheets and cellulose membranes in the form of flat membranes. By this method, a solution of cellulose in an aqueous tertiary amino oxide is extruded by means of an extrusion die having an extrusion gap, the solution taking the shape of a sheet, and is passed via an air gap into a regenerating bath. The method is characterized in that an extrusion die having an extrusion gap at least 40 cm long is used.

摘要： The invention relates to a method for joining objects which each have a surface consisting of a cellulosic material. A joining agent is applied to at least one of the surfaces consisting of cellulosic material and the surfaces consisting of cellulosic material are brought into contact with each other. The inventive method is characterised in that a solution of cellulose in an aqueous tertiary amine oxide, especially N-methylmorphine-N-oxide (NMMO), is used as the joining agent.

摘要： The invention relates to a method for producing flat cellulosic films. A solution of cellulose in an aqueous tertiary amine oxide is shaped into a sheet (4) of film using an extrusion nozzle (2) with a longitudinal extrusion gap (3) and transported through an air gap (5) into a precipitation bath (6), where the flat cellulosic film (12) is formed. The inventive method is characterised in that the side edges (7) of the solution which is shaped into a sheet (4) are brought into contact with and joined to cellulosic strips (8), and in that said cellulosic strips (8) are guided on the side edges of the solution which is shaped into a sheet and optionally of the cellulosic flat film in such a way as to prevent transversal shrinkage.

摘要： The invention relates to a method for producing cellulosic shaped bodies, especially flat or tubular films and cellulosic membranes in the form of flat or tubular films. According to said method, a solution of cellulose in an aqueous tertiary amino oxide, said solution optionally also containing additives such as stabilisers, plasticisers, pore-forming agents and similar, is extruded using an extrusion die to obtain a shaped solution with two surfaces. The extruded shaped solution is guided over a gap into a precipitation bath, then drawn off from said precipitation bath. The method is characterised in that the two surfaces of the shaped solution are each exposed to at least one gaseous medium in the gap, the medium to which the first surface is exposed being different from the medium to which the second surface is exposed in terms of composition, characteristics and/or state of motion.

摘要： The invention relates to a method for producing cellulosic flat films, whereby a solution of cellulose is extruded in an aqueous tertiary amine oxide using an extrusion nozzle comprising an extrusion gap. The solution is shaped in a film-like manner and the extruded solution is guided over an air gap into a precipitating bath. The inventive method is characterized in that an extrusion nozzle is used which has an extrusion gap with a width b for which 220 νm≤b≤280 νm is valid. The invention also relates to flat films which can be obtained according to the amine oxide method and which comprise a thickness d of less than 20 νm, a width B of greater than 30 cm, and a factor f of 65 or less, whereby f is defined as f = d * (MD/TD), d is expressed in νm, and whereby MD represents the strength of the film in the longitudinal direction (N/mm2), and TD represents the strength of the film in a transverse direction (N/mm2).
