    摘要: 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.

    摘要: A process is disclosed for producing shaped cellulose bodies, in particular foils and fibres. A solution of cellulose in a tertiary amine oxide is extruded through a shaping device, for example a spinning nozzle, and the extruded shaped body is drawn as it is led into a aqueous regenerating bath, in which it coagulates. The coagulated shaped body is then washed with an aqueous washing liquid. The process is characterised in that the regenerating bath used for coagulating and/or the liquid used for washing the shaped body contain a dissolved surfactant.
