Definitions

  • the present invention relates to an improvement made to the process implemented on the device which is the subject of FR-A-2520389 corresponding to 1 US-A-4488397.
  • This patent application describes a device which makes it possible to stretch, condense and transport a wick of fibers during a spinning operation.
  • a condenser element is arranged following the drawing system proper, said condenser element being in the form of a movable guide surface on which the fibers are delivered tangentially, this guide surface allowing to exert a tensile force on the end of the fibers delivered by the drawing system and being arranged upstream of a conventional spinning system, for example with rings and sliders.
  • the conventional spinning system can be constituted by a false twist spindle.
  • a false twist pin makes it possible to communicate a certain cohesion to the yarn which, in certain cases, makes it possible to obtain a wire which can be used directly without having to communicate additional twist to it.
  • the invention therefore relates to an improvement to the method allowing the implementation of the device which is the subject of FR-A-2520389 , process which consists, during a spinning operation making it possible to transform a wick of fibers into a spun to stretch said wick by passing it through the drawing system proper followed by a condenser element which is in the form of a movable guide surface on which the fibers are delivered tangentially and which tends to exert a tensile force on the free end of said fibers, the yarn formed being, before winding, subjected to the action of a false twist spindle disposed at the outlet of the condenser element, the method according to the invention is characterized in that the false twist spindle is chosen from the spindles which tend to exert a tensile force on the yarn.
  • an installation which comprises, in a manner similar to that which is the subject of FR_A-2520389 a drawing device d '' a wick of fibers (1) (or ribbon), wick coming from a power source not shown, this drawing system comprising, in the case present, a conventional drawing train designated by the general reference (2) and which consists of a pair of food cylinders (3), a sleeve system (4) and a pair of drawing cylinders (5).
  • the drawing of the wick (1) is carried out between these elements by communicating to them different speeds.
  • a condenser guide (6) driven in rotation at a speed V 2 which can be either equal is different from the speed V 1 of exit from the wick of the cylinders (5).
  • this condenser guide (6) is rotated by any suitable means not shown and is essentially in the form of two truncated cones joined by their top so as to obtain a groove V-shaped whose branches are substantially inclined relative to each other by an angle of about 120 °.
  • the bottom of this groove is pierced with orifices and a suction system is provided inside the condenser (6).
  • a false twist pin (7) is arranged downstream of this condenser guide (6) which not only communicates a twist which rises freely up to the surface of the condenser guide but also, tends to exert a tensile force T on the spun yarn formed.
  • a spindle of known type with crossed belts is used as the false twist spindle (7).
  • a system is arranged call (8), the spun yarn being returned in (9) on a conventional system not imparting additional twist to the spun yarn formed.
  • the yarn formed has improved cohesion compared to the previous yarn obtained by using another type of false twist spindle which does not exert any tensile force on the yarn during its formation.
  • a fiber spun is produced according to the method according to the invention from a polyester wick having a titer of 35,000 Dtex, the fiber cut being 40 mm.
  • the stretching system (2) is adjusted so as to have a stretch of 100, the speed V 1 of the call cylinders (5) being regulated at 15.0 m / min.
  • the condenser guide (6) is driven at a speed of rotation such that the speed V 2 at the bottom of the groove is 150 m / min.
  • the belts of the spindle (7) will be inclined with respect to each other so as to form an angle of 90 ° and the linear speed of said belts is adjusted to 350 m / min.
  • the yarn formed is called at a speed V 3 of 148 m / min
  • a yarn is obtained in (9) having a titer of 350 Dtex which has very good cohesion and can be used as it is without further twisting.
  • the invention is not limited to the embodiment described above, but it covers all the variants produced in the same spirit.
  • it could be envisaged, not to produce simple yarns but core yarns by introducing, in a known manner, a core yarn upstream of the stretching cylinders (5), or even to obtain doubled yarns by treating simultaneously two wicks.
