Definitions

  • the present invention relates to a process for obtaining continuous ring spinning of composite yarns with a core of long fiber yarns surrounded by an outer envelope.
  • the friction spinning process can use continuous, multi or monofilament filaments as well as fiber yarns and does not impart any twist to the core thread
  • the continuous ring spinning processes they use long fibers or short fibers, can use, as thread constituting the core, only continuous filaments, multifilaments or drawn monofilaments.
  • the core is designated by 2 and the cover by 3 .
  • Figure 1 shows a composite wire element made a core 2 and covering fibers 3 , none of these elements having received torsion.
  • the elements 2 and 3 of initial length lo will have a length l ⁇ lo after application of the torsion.
  • This interval covers the range of coefficients commonly used on ring spinning machines, whether long fibers or hem fibers.
  • the core 2 will be overstrained compared to the cover 3 , and the reduction in length ⁇ l of the core 2 will be greater than the reduction in length ⁇ l of the cover 3 .
  • the Applicant in view of this practical impossiblity of making "Core-spun" yarns with a core spun of fibers on a ring spinning machine, firstly endeavored to determine a method of calculating the total coefficient of twist core yarn, so as to be able to optimize the twist coefficient of the fiber yarn to be used as core yarn in order to obtain optimum strength.
  • ⁇ is a function of three variables: ⁇ , ⁇ and h, and is independent of the metric number of yarns.
  • the invention therefore relates to a process for obtaining a composite yarn with a core surrounded by an outer envelope which is characterized in that the core produced, made of long fibers, is twisted during the very operation of spinning performed on continuous ring spinning without reaching its critical twist coefficient, the covering of said core being made of long fibers or short fibers.
  • the twist coefficient of the core wire is between 20 and 85.
  • the material intended to constitute the core consists of a spun of long fibers of high modulus aramid, Nm 90.
  • N dem 27.
  • the coefficient of torsion ⁇ determined on the complete yarn and necessary in short fiber spinning is 90.
  • the resistance of a composite short cover fiber depends only on the resistance of the core wire.
  • R ⁇ Km is the Anac resistance of the complete wire in Km
  • RKm is the mileage resistance of the core wire
  • F ⁇ is the breaking resistance of the whole wire
  • the wires thus obtained which can be obtained in a plate of metric numbers between 1 and 100 have, moreover, and as said above, a quite remarkable resistance.
