Definitions

  • This invention relate to the manufacture of filaments, threads, yarns, ribbons, staple, or similar fibres and the products made therefrom, having the characteristics of natural wool in respect to appearance, feel, serimetric and physical properties.
  • I produce such wool imitation filaments, etc., from cellulose containing vegetable sources according to the viscose method.
  • Fig. 2 is a cross-sectional view of the improved filaments produced by the invention.
  • the viscosity referred to hereinafter is determined according to the ball-fall method, carried out-gin the following manner: The viscose under examination is poured into a vertical glass tube of 300 mm. length and 25 mm. diameter.
  • the composition of the viscose and of the spinning bath cause the filaments produced to have a rough or cracked surface, similar to the scales of natural wool. Furthermore, the filaments twist in such a manner as to have a cross sectionsimilar to a horse shoe, the ends of which touch or overlap, as illustrated in Fig. 2 and Fig. i.
  • Zinc sulphate retards the complete regeneration of the cellulose by quickly forming be able to treat the filaments in the surface, and a hollow, air-enclosing space or canal in the center, as shown in Figs. 2, 3, and 4.
  • a method for the production of artificial wool imitation filaments and the like comprise ing projecting viscose with undcosity of at least 500 into an acid spinning bath containing at least 4% zinc sulphate and approximately 28% sodium-sulphate, withdrawing the filaments under as little tension as possibie by means 0! a first godet wheel and then applying stretch to through a spinneret by'precipitating said viscose into an acid spinning bath containing more than 4%- zinc sulphate and approximately 23% so* chum-sulphate to form filaments, and stretching said filaments to cause said membranes to burst in circumferential .direction of the filaments to impart to the filaments a rough surface.
