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, which is known from the document GB-A-1 592 665.
  • 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 for the yarns, 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 core loops are important for the appearance and the textile feel of the products. Although 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 that 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 transmission from 1.03 to 1.2 and at least one fancy yarn strand with a transmission from 1.2 to 4.
  • the object of the invention is to design the blow texturing device specified at the outset in such a way 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 an equal mixing of 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 guided out of the axis of the guide body bore by means of a thread guide or on a baffle surface.
  • the running yarn is always deflected in such a way that the yarn remains in a central plane which contains the axis of the guide body bore and the axis of the blowing medium supply bore.
  • the stated object can be achieved by designing the blast texturing device in such a way that a yarn emerging from the outlet opening of the guide body is deflected out of a central plane which defines the axis of the guide body bore and the area center of gravity of the mouth cross section or Mouth cross-sections of one or more blowing medium supply bores opening into said annular space contains which surface center of gravity is at a distance from the axis of the guide body bore.
  • the device according to the invention is characterized in a first embodiment in that a thread guide pin is arranged on the impact body, which deflects a yarn emerging from the outlet opening of the guide body bore and guided around the thread guide pin out of a central plane, which axis the axis of the guide body bore and contains 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 device according to the invention is characterized in that the impact body has a thread guide groove which deflects a yarn emerging from the outlet opening of the guide body bore and guided through the thread guide groove out of a central plane, which axis the axis of the guide body bore and the center of area of the mouth cross section or contains the mouth cross-sections of one or more blowing medium supply bores opening into said annular space, which area center of gravity is at a distance from the axis of the guide body bore.
  • the device according to the invention is characterized in that the impact body has a cylindrical circumferential surface at least in the region of the outlet opening of the guide body bore and that the axis of this cylindrical circumferential surface with a normal to a central plane, the axis of the guide body bore and the center of area of the mouth cross section or contains the cross-sections of one or more blowing medium supply bores opening into the said annular space, which area center of gravity is at a distance from the axis of the guide body bore, forms an acute angle, for example an angle of 2 to 30 °, so that the impact body deflects a yarn emerging from the outlet opening of the guide body bore and laid around the impact body out of the said central plane.
  • 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.
  • a baffle 9 is arranged on the exit side of the bore of the guide body 1 and has, for example, 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 into the annular space 7 through preferably two blowing medium supply bores 11 and 12.
  • 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 circumferential area of the impact body 9 that extends over an obtuse angle ⁇ 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.
  • 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.
  • the same texturing device was used for comparison purposes, but with only one air supply hole and without the thread guide pin (not according to the invention).
  • the tensile force in the textured yarn leaving the impact body was 7.5 cN.
  • the yarn had a fairly closed structure, but with sometimes larger, unevenly distributed loops.
  • the device according to the invention thus achieved an increase in the thread tension by 50% and at the same time an improvement in the yarn uniformity, which can be estimated at about 25%.
  • 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 from 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 shapes, or even just one feed bore or more than two feed bores, are also possible.
  • 6 to 11 show, in views similar to FIG. 3, the mouths of various usable feed bores.
  • the center of gravity A of the muzzle cross section or the muzzle cross sections is also shown in each case, and likewise 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 hole consists of two approximately circular sections which are connected to one another by a narrow slot section.
  • FIG. 9 shows, similar to FIG. 3, two feed bores 11.4 and 12.4, which, however, have oval cross-sectional shapes.
