Definitions

  • This invention relates to the production of filaments and more particularly to thermoplastic filaments having a crimp making them suitable for use in bulked yarn.
  • Thermoplastic filaments have been produced by extruding them through a spinnerette and taking them up on a suitable take-up apparatus, the filaments being quenched by contact with air which impinges on them just after their formation.
  • the art is crowded with various ways of providing the quenching air.
  • the filaments are then gathered into so-called yarn and the filaments are oriented by drawing and annealed by relaxing them at an elevated temperature.
  • specific conditions are employed in this process with specific thermoplastic materials, bulked yarns having special characteristics are provided.
  • FIGURE 3 is a vertical cross-section along the line 3-3 of FIGURE 2.
  • the wall 23a is provided with a ring of air openings 24 inside the skirt and spaced a given distance from the position the filaments F assume when the spinning operation is being carried out.
  • the ring of" air openings 24 is also concentric with the ring of spinning orifices 15.
  • the end of the extrusion tube 13 is externally threaded as at 13a.
  • the manifold 17 is internally threaded as at 17a and thereby mounted on the end of the extrusion tube with a gasket 16 intervening the end of the extrusion tube 13 and a part of the manifold 17.
  • the take-up speed be less than about 200 linear feet per minute, with the curtain of air formed by the air jets having an effective length from approximately one-half inch to two and one-half inches below the spinnerette.
  • the curtain of air formed by the air jets having an effective length from approximately one-half inch to two and one-half inches below the spinnerette.
  • the air leaving the feed holes can be at room temperature and need not be cooled, but must not be too warm to impair its quenching effect.
  • Yarn take-up speeds of between sixty and two hundred feet per minute are effective.
  • yarns of 3750 denier were spun at one hundred and twenty feet per minute and grams tension. This corresponds to 24 mg. per denier.
  • the applicant prefers a tension between about 70 and about 120, corresponding to about 19 to about 32 mg. per denier.
  • Example 2 A yarn of '615 denier, 50 filaments, was extruded from a polypropylene Pro-fax of a 3.5 Melt Index as manufactured by Hercules Powder Company. Yarn was taken up at a speed of 190 feet per minute. The yarn was cooled using 0.5 c.f.m. of air at the spinnerette. Extrusion temperature as measured in the melt just before it entered the spinnerette was 271 C. Yarn tension between the spinnerette and the first guide was found to be 17 grams corresponding to 28 mg. per denier. The yarn was then drawn at a temperature of 70 C. by a ratio of 2.5, the actual draw on the yarn being about 2.1 as the yarn tends to shrink between the outlet roll and the take-up mechanism.
