VERFAHREN ZUR HERSTELLUNG CELLULOSISCHER FORMKÖRPER
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.
