  • Patent number: 4045532
    Abstract: A continuous process for producing viscose yarn including feeding a viscose solution through spinneret dies into a spinning bath to spin viscose yarn, and finally regenerating and concurrently cooling the spun yarn, now carrying entrapped carbon bisulfide in the form of an emulsion, from said spinning bath at a temperature below the boiling point of the carbon bisulfide. Thereafter, while maintaining the finally regenerated yarn in a cooled condition, washing the yarn with water whereby some water, in addition to the carbon bisulfide, becomes entrapped in the yarn, subjecting the washed yarn to avivage treatment, and finally drying the resulting yarn at an elevated temperature sufficient to concurrently remove both the entrapped water and the carbon bisulfide from the yarn. Thereafter, the resulting dried and carbon bisulfide-free yarn is wound into a package.

  • Patent number: 3972209
    Abstract: An apparatus for washing freshly spun artificial yarn during its movement relates to the finishing of yarn such as viscose yarn. By this apparatus, yarn is intermittently saturated with a finishing solution on that portion of a rotating roll which extends outside the finishing solution contained in a tank. Between the saturation zones, the yarn is spaced apart from the roll surface for diffusion and squeezing of yarn. In order to ensure the intermittent saturation of yarn with the finishing solution, the yarn is displaced in the direction opposite to the rotational direction of the roll. An additional roller engages with the driven roller displacing the yarn so as to form a squeezing pair therewith, and there is an additional tank having a scraper. The scraper is in permanent contact with the roll surface below the zone of feeding the yarn thereto and is adapted to remove the layer of finishing solution from the roll surface.
