Definitions

  • the invention relates to a device for blast texturing of at least one multifilament yarn, with a guide body, which has a continuous bore with a conical inlet section and an outlet opening, with a needle body, which contains a continuous yarn channel which is approximately coaxially aligned with the bore of the guide body extends with one end into said conical entry section and has a circumferential surface which forms with the wall of the conical entry section a passage gap for a blowing medium which can be introduced into the annular space surrounding the needle body in front of the passage gap, and with one on the exit side of the bore of the Guide body arranged impact body.
  • the cohesion of the filaments plays an important role. Yarns with good internal cohesion are not only easier to work with, they also have a higher abrasion resistance in use. This results in a higher utility value of the yarn, e.g. as sewing threads, or the textile fabrics made with the yarns.
  • the inner cohesion of textured multifilament yarns is often referred to as the entanglement level.
  • the textured multifilament yarns have the property that filaments protrude from a thread core part and are formed into loops.
  • the shape and distribution of the from the thread core part outstanding loops are important for the appearance and the textile feel of the products.
  • the shape and distribution of the loops are largely determined by the type of yarn and the settings (pressure of the blowing medium and yarn feed and take-off speed into and out of the texturing device), the blowing texturing device also makes an important contribution.
  • a good texturing device should have the ability to distribute the loops evenly and press them against the thread core part.
  • the distribution of the filaments in the yarn structure is also important, for example it is responsible for the uniformity of the color component distribution in yarns which are produced from master yarns with filaments of different colors or with differently colored filaments. Such yarns are typically used to make seat covers. Massages of individual color components are very disruptive in the finished product.
  • An effective blowing texturing device is expected to produce a uniform, compact texture even with a high yarn delivery.
  • the yarn delivery is defined as the ratio of the yarn feed speed into the texturing device to the take-off speed, and is calculated separately for each individual strand of yarn fed to the nozzle.
  • at least two multifilament yarns or skeins are supplied for high-handed yarns, namely a core yarn or stand-up yarn with a tradition of 1.03 to 1.2 and at least one fancy yarn skein with a tradition of 1.2 to 4.
  • the object of the invention is to design the blow texturing device specified at the outset so that the textured yarn emerging from the device has a higher tension than in known blow texturing devices, as a result of which the entanglement level of the yarn is higher, and at the same time that the filaments in the yarn and a more evenly distributed loop structure with loops tied more tightly to the thread core can be achieved.
  • a feed hole for the blowing medium opens into the annular space surrounding the needle body in front of the passage gap at a distance from the axis of the guide body bore.
  • the yarn leaving the exit opening of the guide body is deflected on a cylindrical impact body surface, the axis of which is perpendicular to a central plane which passes through the axis of the guide body bore and through the axis of the blowing medium supply bore.
  • the running yarn remains in this middle plane.
  • the device according to the invention is characterized by such a configuration and / or arrangement of the impact body and / or of thread guiding elements that a yarn emerging from the outlet opening of the guiding body is deflected out of a central plane, which is the axis contains the guide body bore and the area center of gravity of the mouth cross section or the mouth cross sections of one or more blowing medium supply holes opening into said annular space, which area center of gravity is at a distance from the axis of the guide body bore.
  • the needle body contains two ends that open into said annular space Blowing medium supply bores, which are arranged symmetrically to one another with respect to the central plane.
  • the device for blast texturing of at least one multifilament yarn has a guide body 1, for example made of ceramic material, which contains a continuous bore with a conical inlet section 2 and an outlet opening 3. Furthermore, the device has a needle body 4 which contains a continuous yarn channel 5 which is aligned coaxially with the bore of the guide body 1.
  • the needle body 4 extends at one end into the conical entry section 2 of the bore of the guide body 1 and has on this end a conical circumferential surface which, with the wall of the conical entry section 2, forms an annular passage gap 6 for a blowing medium, which in the The annular body 7 surrounding the needle body 4 can be inserted in front of the passage gap 6.
  • an impact body 9 is arranged, which for example has the shape of a cylindrical pin.
  • a circumferential recess 10 in the needle body 4 stands with one, not shown Blowing medium connection, eg compressed air connection, in connection.
  • the blowing medium is guided out of the recess 10 through preferably two blowing medium supply bores 11 and 12 into the annular space 7.
  • the area center of gravity A of the cross sections of the mouths of the bores 11 and 12 in the annular space 7 has a distance a of, for example, 3 to 10 mm from the axis of the bore of the guide body 1.
  • the center of area A and the axis of the bore of the guide body 1 determine a central plane M of the device.
  • the yarn channel 5 of the needle body 4 is supplied, for example, with two multifilament yarns to be combined and textured, namely a core yarn F1 and a fancy yarn F2.
  • the core yarn F1 can be wetted by an applicator (not shown), for example with water, immediately before entering the yarn channel 5.
  • the multifilament yarns are blown through the blown medium jacket, which emerges from the passage gap 6. This will swirl the yarns together.
  • the combined yarn is deflected on the impact body 9. It runs around the impact body 9 and then as a textured yarn FT to a thread guide 13.
  • This thread guide 13 is arranged in such a way that the yarn wraps around a peripheral region of the impact body 9 which extends over a blunt whirl ⁇ and then one to the axis of the bore of the guide body 1 parallel plane E penetrates, which goes through the center of area A and is perpendicular to the central plane M.
  • the yarn emerging from the outlet opening 3 of the guide body 1 is deflected out of the center plane M.
  • a tension of the textured yarn leaving the impact body 9 can be achieved FT can be achieved, which is higher than a yarn that remains between the outlet opening 3 and the impact body 9 in the central plane.
  • This increases the yarn's entanglement level accordingly.
  • a more equal mixing of the individual filaments and more evenly distributed loops, more tightly bound to the thread core, are achieved.
  • a thread guide pin 14 is arranged on the impact body 9 for deflecting the yarn from the central plane M.
  • the deflection y of the yarn out of the central plane M is at least 0.5 mm, preferably 2 to 8 mm.
  • a textured yarn was produced from a core yarn made of polyester dtex 167f72, which was wetted by a water-carrying applicator before entering the texturing device, and a fancy yarn made of polyester dtex 167f72x2.
  • the withdrawal speed of the textured yarn was 300 m / min.
  • the feed speed of the core yarn was 336 m / min (tradition 12%).
  • the feed speed of the fancy yarn was 555 m / min (tradition 85%).
  • a texturing device as shown in FIGS. 1 to 3 was used, with two air supply bores of 1.41 mm in diameter on a pitch circle with a radius of 8.3 mm.
  • the thread tension in the textured yarn leaving the impact body 9 was 11.5 cN.
  • the textured yarn had one compact structure with many small, evenly distributed loops.
  • FIG. 4 shows, in a view similar to FIG. 2, a modified embodiment of the invention, in which the impact body 9.1 instead of the thread guide pin 14 of FIG. 2 has a groove 15 which the yarn emerging from the outlet opening 3 out of the central plane M. distracts.
  • the impact body 9 again has the shape of a cylindrical pin.
  • the thread guide pin 14 is also omitted here.
  • the axis p of the impact body is inclined at an acute angle ⁇ to a normal n to the center plane M, so that the cylindrical peripheral surface of the impact body 9 deflects the yarn out of the center plane M.
  • the angle ⁇ can be approximately 2 to 30 °.
  • the two feed holes 11 and 12 shown in FIGS. 1 to 3, which are circular in cross section, are preferably used, not only because of their simple shape, but also because of the good effect which is achievable.
  • feed bores with any other cross-sectional shape, or even just one feed bore or more than two feed bores, are also possible.
  • 6 to 11 show the mouths of various usable feed bores in views similar to FIG. 3.
  • the center of gravity A of the cross section of the mouth or the cross sections of the mouth is also shown in each case, as is the central plane M passing through this center of gravity A and the axis of the guide body bore, from which the yarn emerging from the guide body bore is deflected as described.
  • FIG. 6 shows a feed bore 11.1 in the form of a slot curved around the axis of the guide body bore.
  • the slot could also be straight.
  • Fig. 7 shows a feed bore 11.2, which has the shape of a profiled slot.
  • the cross section of this bore consists of two approximately circular sections which are connected to one another by a narrow slot section.
  • FIG. 9 shows, similarly to FIG. 3, two feed bores 11.4 and 12.4, which, however, have oval cross-sectional shapes.
