Definitions

  • the invention relates to a device for treating at least one running multifilament yarn with a blowing medium, with a continuous yarn channel which is circular in cross-section and has a cylindrical middle section, into which a number of blowing medium supply bores open laterally.
  • blowing medium generally compressed air
  • the blowing medium serves to change the mutual spatial arrangement of the filaments in the multifilament yarn, to change the appearance and feel of the yarn and / or to improve the cohesion of the filaments in the yarn for further processing.
  • the known devices are, for example, texturing devices to which one or more multifilament yarns are fed at a speed which is higher than the rate at which the yarn is drawn out of the device.
  • the speed difference usually referred to as tradition, can be about 10 to 30%.
  • the yarns fed are generally smooth yarns, on which the blowing medium in the yarn channel from one or more blowing medium supply holes inclined to the axis of the yarn channel impinges.
  • the treated textured yarn has a compact core in which the filaments are closely intertwined and from which filament loops protrude.
  • the yarn is not elastic.
  • the filament loops protruding from the surface are also disadvantageous for some applications, since they can easily get caught.
  • swirling devices Other known devices are called swirling devices.
  • a multifilament yarn or several multifilament yarns with only a small amount Traditionally, at most about 10%, passed through the yarn channel, in which they are supplied with blowing medium from a blowing medium supply bore, the axis of which is approximately perpendicular to the axis of the yarn channel.
  • This treatment creates swirling nodes in the yarn at more or less regular intervals, in which the filaments of the yarn are intertwined. This gives the filaments the necessary cohesion for further processing of the yarn. Filament loops practically do not arise.
  • the multifilament yarn supplied can be smooth or, for example, false twist textured. If it is elastic, then the yarn is still elastic after treatment in the intermingling device.
  • the non-uniform structure of the yarn with the discrete interlacing knots separated by non-interlaced areas, can interfere with certain applications.
  • the separate intermingling knots do not completely disappear during further processing (e.g. during weaving or knitting and possibly finishing) and can produce undesired moiré effects in the end product.
  • the invention has now set itself the task of designing the device specified at the outset in such a way that multifilament yarns can be treated in such a way that the filaments of the fed multifilament yarn or multifilament yarns are interwoven uniformly along the length of the yarn without forming separate interlacing knots and form practically no protruding filament loops.
  • the device according to the invention is characterized in that the number of blowing medium supply bores is three and that these bores are arranged at equal angular intervals from one another such that their axes align the axis of the yarn channel at a common point under each Cut angles from 15 to 40 °.
  • the yarn channel preferably has a conically narrowing in front of the cylindrical central section Inlet section and after the cylindrical central section a trumpet-shaped widening outlet section.
  • a yarn with the desired properties specified above can be obtained if the device is fed a multifilament yarn or multifilament yarns with a delivery in the range from 0 to at most 15% and the treated yarn from the outlet of the device transversely to the axis of the yarn channel, preferably at an angle of approximately 90 ° to the yarn channel axis.
  • the body shown in FIGS. 1 to 3 consists of two superimposed parts 11 and 12.
  • recesses are provided which together in the operating position of the two parts, according to FIGS. 1 and 2 define a continuous yarn channel with a circular cross section, which consists of a conically narrowing inlet section 13, a cylindrical middle section 14 and an outlet section 15 that widens in the shape of a trumpet.
  • the cylindrical middle section 14 of the yarn channel has a diameter of 1 to 2 mm, preferably about 1.2 mm.
  • Three blowing medium supply bores 16, 17 and 18 open laterally into the cylindrical middle section 14 of the yarn channel and are distributed at equal angular intervals from one another about the axis of the yarn channel.
  • the axes of the bores 16, 17 and 18 intersect the axis of the yarn channel 13, 14, 15 at a common point each at an angle in the range from 15 to 40 °, preferably 25 to 35 ° and most preferably about 30 °.
  • the three bores 16, 17 and 18 all have the same diameter or slightly different diameters in the range from 0.4 to 0.8 mm. All three bores preferably have the same diameter in the range from 0.55 to 0.65 mm, ideally about 0.6 mm.
  • a multifilament yarn M1 or more multifilament yarns are fed to the yarn channel 13, 14, 15.
  • the fed multifilament yarns can be smooth and / or textured yarns from e.g. Be polyamide and / or polyester.
  • blowing medium supply bores 16, 17 and 18 are supplied with a blowing medium, generally compressed air at ambient temperature, from an inlet 19 via a feed bore 20 which leads to the bore 16 and a feed bore 21 which leads to the bore 18 and to a chamber 22 leads from which the bore 17 starts.
  • a blowing medium generally compressed air at ambient temperature
  • the multifilament yarn M1 or the multifilament yarns to be treated are each fed to the yarn channel 13, 14, 15 with a tradition in the range from 0 to at most 15%, preferably at most 10%, and that the treated Yarn from the Pull the outlet of the yarn channel as shown in a direction transverse to the axis of the yarn channel. If several multifilament yarns are fed in at the same time, the delivery, ie the percentage by which the feed speed is higher than the take-off speed of the treated yarn, can always be the same for all yarns fed or also different for different yarns fed, in the specified range up to a maximum of 15% .
  • the body of the preferred embodiment of the device according to the invention shown consists of the two parts 11 and 12. As indicated, these are arranged in a holder 23 schematically indicated in FIG 1 and 2 and a threading position according to FIG. 3. In the operating position, the recesses in the mutually facing side surfaces of the two parts 11 and 12 limit the yarn channel 13, 14, 15 as indicated. In the threading position shown in FIG however, at least one of the two recesses, in the special case the recess in part 12, is exposed for the insertion of multifilament yarn.
  • the holder 23 contains a blowing medium supply channel 24.
  • the blowing medium inlet opening 19 provided in this part 12 is aligned with the mouth of the blowing medium supply channel 24, so that blowing medium is removed therefrom Channel 24 enters the feed bores 16, 17 and 18 and is ejected through them into the yarn channel 13, 14, 15. If the part 12 is shifted from the operating position into the threading position according to FIG. 3 by a mechanism (not shown), the part 12 closes the mouth of the blowing medium supply channel 24 and the supply of blowing medium into the inlet 19 is interrupted.
  • a partially oriented polyester multifilament yarn with the titer 90f40 was subjected to conventional stretch texturing at 500 m / min.
  • the product of the stretch texturing was a highly elastic polyester yarn with the titer 50f40.
  • the thickness of this yarn as a function of the yarn tension is represented by curve A in FIG. 4.
  • a treatment device was arranged as described above with reference to FIGS. 1 to 3. At this point, the stretch texturing process has ended.
  • the highly elastic textured yarn was introduced with a tradition of 5% into the yarn channel of the treatment device, without wetting.
  • the highly elastic yarn obtained as a product of the stretch texturing was spun with 200 twists per meter.
  • the thickness of the spun yarn as a function of the tension is represented by curve C in FIG. 4.
  • the further processability of the yarn treated in the device according to the invention is greatly improved in comparison to the drawn textured yarn, which is e.g. when unwinding at high speed and when inserting weft during weaving.
  • the filaments in the yarn are intertwined in such a way that the yarn can be used to produce fabrics with a very uniform structure and uniform dyeability.
