Definitions

  • the present invention relates to a process for the production of polyester monofilaments with a titer of 1 to 30 dtex and the monofilaments produced thereafter.
  • Fine monofilaments up to about 33 dtex are spun at spinning speeds of less than 1000 m / min, cooled with blown air, wound up and drawn separately in a second operation at about 750 m / min.
  • EP-A-0176937 describes a method for producing a smooth multifilament yarn, the filament bundle being combined into a thread, then wetted with liquid by means of a water nozzle and then stretched over a brake pin.
  • the multifilament plain yarn obtained in this way is intended as a roving for texturing or for the production of stretch yarn.
  • GB-A-712 799 describes a method and an apparatus for drawing polyamide yarns.
  • a further cylinder pair or pin pair is provided between a drafting system consisting of a delivery godet and a take-off godet, which is able to stabilize the thread tension during the stretching process via a spring system.
  • a drafting system consisting of a delivery godet and a take-off godet
  • Such a system is unsuitable for the rapid spinning of polyester monofilaments, if only because of its complex composition.
  • the object of the invention is to provide a process for the production of fine monofilaments which achieves and / or improves the properties of known monofilaments without a separate stretching process at high winding speeds.
  • Another object is to vary the method in such a way that desired properties of the monofilaments can be achieved by the setting parameters of the device.
  • the winding speed is 3000 to 6000 m / min., Preferably 4000 to 5000 m / min.
  • thermoplastics such as all kinds of polyesters, polyamides, especially those known as nylon 66 or nylon 6, and polyacrylic, polyvinylidene fluoride, made of polyethylene or polypropylene.
  • the device for carrying out the method essentially consists of a friction element which is arranged between the spinneret and the device for the preparation application.
  • the friction element is preferably fork-shaped formed, rotatable and movable in its distance from the spinneret.
  • the two opposite friction surfaces, an upper friction surface and a lower friction surface are arranged axially parallel.
  • a friction element which has been set and fixed once at a distance from the spinneret can be rotated about its axis continuously or in fixed steps in such a way that a desired tension can be provided on the thread lying between the friction surfaces.
  • the step-by-step adjustment has the advantage that the desired positions can be precisely re-adjusted at any time and a constant, reproducible thread tension is guaranteed.
  • the friction element can consist of several pins, which have a cylindrical but also oval surface. However, other bodies with curved surfaces can also be used.
  • a distance of the friction elements from the spinneret that is 20 to 280 cm, depending on the desired final titer of the monofilament.
  • the twist angle ⁇ between the thread path and the common axis of the friction element surfaces should be 0 to 40 degrees and the wrap angle of the friction element / monofilament should be 50 ° to 150 °.
  • the invention is to be illustrated schematically on the basis of a drawing.

  • a friction element 3 is arranged between the spinneret 1 and a winder 7.
  • the height of the friction element 3, as indicated by arrows, is adjustable.
  • the friction element 3 consists of a friction surface 4 and a friction surface 5, which are arranged about an axis 8.
  • the friction element 3 is rotatable so that a monofilament 2 or a family of monofilaments which is passed between the friction surface 4 and the friction surface 5 and which is represented by the monofilaments 2 and 2 ′ delimiting the thread family can be subjected to a frictional force.
  • a device 6 for applying a spin finish is provided between the friction element 3 and the winder 7.
  • Fig. 2 the rotatability of the friction element is indicated by arrows.
  • Fig. 2a the monofilament 2 passes between the friction surface 4 and the friction surface 5.

  • Fig. 3a the thread passes between the frosted surface 4 and the friction surface 5.
  • Figure 3b is a side view of Figure 3a.
  • Fig. 4b is a side view of Fig. 4a.
  • a group of threads emerges from the spinneret 1, consisting of the monofilaments 2, 2 'delimiting the group, which run parallel through the friction element at high speed and are stretched over the friction surface 4 and the friction surface 5 by means of the winder 7.
  • a suitable spin preparation 6 is applied on the path between the friction element 3 and the winder 7. If necessary, a godet can also be arranged between the friction element and the winder.
  • the resulting monofilament is a finished product for further processing.
  • Polyester with a V.I. of 74 dl / g and a melt temperature of approx. 287 ° C is extruded through a spinneret 1 x 6 / 0.33 / 4D and drawn off at a speed of 5000 m / min and blowing air at 0.25 - 0.4 m / s chilled.
  • the distance between the spinneret and the friction element is 30-160 cm, depending on the titer.
  • a spinning preparation is applied to the thread at a distance of h + 40 cm.

Abstract

Dans ce procédé pour le filage rapide simultané de plusieurs monofilaments ayant un titre de 1 à 30 dtex, les monofils sont refroidis par soufflage d'air, levés sur un frottoir et bobinés directement. Le dispositif se compose d'un frottoir (3) avec des surfaces de frottement parallèles (4, 5). Le frottoir (3) se déplace dans le sens de la hauteur et peut pivoter pour régler le frottement entre ce frottoir et un monofil (2) ou un groupe de monofils. Le monofilament produit possède une résistance de 36 à 60 cN/tex, un allongement de 20 à 40 % et un retrait à la cuisson de 2 à 15 %.
