ABSTRACT:
The removal of water from viscose rayon yarns in the continuous spinning of such yarns is improved by subjecting the yarns to the action of an air jet before the thermal drying treatment. The air jet impinges on the yarns adjacent their passage from the last liquid treatment zone to the drying zone and is directed approximately tangentially to the treatment roller, that is to the helicoidal path of the yarn. The removal of the water is completed by thermal drying. Up to 50% of the water content, and several times the dry weight of the yarn, is eliminated by the pneumatic treatment. The air jet is directed on the yarn by means of a slit-shaped nozzle having its larger dimension substantially parallel to the treatment roller. A plurality of yarns can be treated concurrently on the same device having a plurality of guide rollers.
