发明名称 Process and device for the production of cellulosic moulded bodies
摘要 The invention relates to a process for the production of a spunlaid fabric containing solvent-spun cellulosic fibres. The process is characterised in that a solution of cellulose in an aqueous tertiary amine oxide is extruded through a spinneret (1) with orifices and the extruded filaments (3) are stretched in an air gap and led into a precipitation bath (2), the filaments in the precipitation bath (2) are intercepted by a first conveyor device (5) whereby a curtain of threads of filaments basically arranged parallel to each other and basically of constant thickness is formed on the first conveyor device (5), the curtain of threads is transported by means of the first conveyor device (5) out of the precipitation bath (2) onto a second conveyor device inclined downwards (8), and the curtain of threads is transported downwards on the second conveyor device (8) onto a third conveyor device (10), where the third conveyor device (10) draws off the curtain of threads at a speed less than the speed of the curtain of threads transported downwards on the second conveyor device.
