Definitions

  • Hollow artificial textile fibers have been heretofore obtained by various means either by spinning or drawing a solution adapted to yield artificial textile fibers, for instance suitably matured viscose, forming an emulsion with air or some other suitable fiuid, or by spinning or drawing a viscose, in which has been embodied a body calculated to emit under chemical action gaseous bubbles within the fiber after the latters issue from the spinning machine or draw-plate; or by spinning or drawing viscose, in which has been dissolved air or any other gas that has been kept dissolved until after or immediately before issue from the spinning machine or draw-plate.
  • the object of my invention is to provide a novel hollow textile fiber, continuous, discontinuous, or in flocks, endowed with all the properties of the gas-imprisoning hollow textile fiber but afi ording besides. most valuable qualities of suppleness and elasticitv.
  • This artificial textile fiber according to my invention is manufactured like the'aforementioned fiber either by means of a suitable matured viscose emulsion. or by means of any other spinnable or drawable matter and of a neutral gas such as air or by means of a viscous or other substance capable of emitting during or before coagulation a gas producing a hollow fiber.
  • the product After the gas-cored fiber has been obtained the product is subjected to the action of a fiuid calculated to condense, dissolve or absorb the gas contained within the fiber.
  • a fiuid calculated to condense, dissolve or absorb the gas contained within the fiber.
  • the imprisoned gas is air, for instance, water deprived of air by boiling will achieve the result, or the textile fiber may merely be treated with water under pressure.
  • carbonic acid is employed to produce the hollow fiber, plain water or such baths as areused to treat the thread after its issue from the spinning machine or draw plate will generally quite readily dissolve the imprisoned gas. Of course elimination of the said gas can be either complete or partial.
  • Figure 1 is a sectional view of a solid artificial textile fiber, that is to say of an ordinary fiber as seen through a microscope; the shapes of such sections varying very much indeed.
  • Figure 2 is a sectional view of a hollow artificial textile fiber.
  • Figure 3 is a sectional view of a hollow artificial textile fiber, from the interior of which the gas has been partly eliminated.
  • Figure 4 is a sectional view of a hollow artificial textile fiber with the gas practically entirely exhausted.
  • Figures 5 and 6 are theoretical views showing sections of a solid artificial textile fiber and of a hollow artificial textile fiber obtained by the process according to my invention, and allowing a comparison as to siz s.
  • Figures 1, 2, 3 and 4 afi'ord a clear demonstration of the difierences that exist in cross section between a solid fiber a, a hollow fiber I) with gas inside, and a hollow fiber c from which the gas has been removed by, say, dissolving.
  • the herein-described process comprising the steps of forming, from a suitablymatured viscose solution, a filament containing air, and then extractingthe air to cause the walls of the filament to collapse.
