Definitions

  • Glitter is the property of the yarn relating to the yarn's ability to reflect incident light.
  • the amount of glitter exhibited by a yarn is a measure of the relative fraction of light that is reflected by the yarn.
  • Bath is the property of the yarn, which most closely correlates to surface coverage ability of a given yarn.
  • the orifices 56-1, 56-2 and 56-3 are arranged with respect to each other such that one leg of each orifice 56-1, 56-2 and 56-3, e.g., the leg 62A, extends from the junction point 68 in a radially outward direction relative to the central point 58. Stated alternatively, the radially outwardly extending leg 62A of each orifice 56-1, 56-2 and 56-3 is oriented such that its axis 64A aligns with a radius 70 extending outwardly from the central point 58. Each junction point 68 of the orifices 56-1, 56-2, 56-3 respectively corresponds to a major apex 34A, 34B, 34C of the void 30 of the filament being spun.
  • Trilobal cross sections with voids have been practiced in the past [e.g., United States Patent 6,048,615 (Lin)].
  • hollow filament yarns are difficult to make because of cross section shape control.
  • Void percent and exterior modification ratio are both sensitive to polymer viscosity and quench air flow.
  • lack of cross section shape uniformity can result in streaks when the yarns are finally tufted into a carpet.
  • the polymer was extruded through the different spinnerets and divided into two (2) sixty-eight filament (68) segments.
  • the capillary dimensions for the spinnerets are described below.
  • the molten fibers were then rapidly quenched in a chimney, where cooling air at about nine degrees Centigrade ( ⁇ 9 °C) was blown past the filaments at three hundred cubic feet per minute [300 cfm (732 m/min)] through the quench zone.
  • the filaments were then coated with a lubricant for drawing and crimping.
  • the coated yarns were drawn at 2197 yards per minute (2.75 x draw ratio) using a pair of heated draw rolls.
  • the draw roll temperature was one hundred ninety degrees Centigrade (190°C).
