Abstract (en)
[origin: WO9607778A1] A process for producing a cellulose moulding, especially cellulose fibres, by the combination of steps in which a cellulose-containing material is introduced into an aqueous solution of a tertiary amine oxide in order to put it in suspension, water is extracted from the suspension with intensive mixing and the application of high temperature and reduced pressure until a cellulose solution is formed, and the solution is moulded using a moulding tool, especially a spinneret, in order to precipitate the dissolved cellulose, with the condition that the dissolved cellulose consists essentially of shredded waste paper, shredded waste cellulose-containing fabrics and/or shredded, mechanically and/or chemically digested annual plants.
