Abstract

<PICT:0925741/IV(a)/1> The gases evolved during the production of viscose rayon are recovered undiluted by air by extruding bundles of filaments upwards from a row of spinning nozzles 3 (Fig. 1) situated in a spinning bath 2, each bundle of filaments being drawn into and through a vertical tube 4 situated above the corresponding spinning nozzle and forming one of the inlet limbs of a syphon. The lower end of each tube 4 dips into the spinning bath 2 and the upper end of each vertical tube 4 opens into the substantially horizonal portion 1 of the syphon into which the bundles of filaments are drawn to form a tow of increasing cross-section as the tow travels towards the outlet or discharge limb of the syphon. The tow is drawn from the portion 1 of the syphon into and through the vertical discharge limb of the syphon, the lower end of which limb dips into a body of spinning bath liquid located at a lower level than the spinning bath 2 and contained in a tank 5, the syphon outlet being thereby hydraulically sealed. The tow is withdrawn from the discharge limb of the syphon round the guide 12 and out of the liquid in the tank 5 by means of the squeeze rolls 7. The spinning bath liquid flows through the syphon at a linear velocity lower than that of the tow into the tank 5 which is covered by a hood 5a the side walls of which dip into the spinning bath liquid in the tank 5 so that the gas space under the hood is hydraulically sealed, the gas being discharged from the hood by the pipe 10 the outlet end of which is also hydraulically sealed. The lower or inlet end of each vertical tube 4 is provided with a funnel-shaped enlargement. The horizontal portion 1 of the syphon and also the curved portion thereof are provided with transverse ribs 12 which serve as stationary guides for the individual fibre bundles drawn from the top of each tube 4 and for the tow of increasing size formed by the assembling of these bundles. The ribs 12 also cause the flow of liquid through the syphon to be turbulent.
