Definitions

  • the invention is in the field of connecting an endless elastane thread with or multiple staple fiber yarns or two or more staple fiber yarns by air turbulence.
  • Such connections of yarns have so far been used for the production of elastic yarns used, the possible uses of which have increased significantly recently (e.g. underwear, Sportswear, outerwear, shirts, pullovers).
  • Elastic yarns are increasing Mass processed as composite yarns, namely in the form of wrapping yarns (wrapping twists), Double wire twisting and wound yarns (core yarns).
  • the filament yarn is aerodynamically interlaced with the elastane a kind of loop yarn (thread).
  • the swirled yarn shows large Volume differences, whereby the elastane component with the filament yarn is only punctiform connected and the elastane is partially visible.
  • the thread is the Depending on the selected expansion factor, the elastane component is largely encased and practical invisible, and the twisted yarn shows a relatively even structure.
  • this device is now to be improved in such a way that it enables high yarn speeds and the lowest possible cost of the device, the economy of the AC process can be increased significantly.
  • the present invention relates to a device for connecting an endless elastane thread with at least one staple fiber yarn or two or more staple fiber yarns by means of one behind the other arranged nozzles in which a twist is applied to the threads.
  • the device according to the invention is characterized in that two nozzles are provided and that in the yarn running direction before and after the second nozzle and between them a swirl stopper is arranged.
  • the ends of the staple fibers become binders used by wrapping the protruding ends of the flax fibers around the entire endless thread or around the whole staple fiber yarn, which makes the twisted yarn one shows uniform structure and the wrapping yarn formed has a high stability and very well processed, for example twisted, twisted (counter wire or on wire) or can be knitted.
  • the device according to the invention serves as an accompanying function for folding to form the elastic yarn with one or more staple yarns and enables the perfect "twisting" of elastic yarns made of pure cotton on double wire machines, which was previously not possible.
  • the device according to the invention differs from the device mentioned at the beginning with the three nozzles arranged one behind the other by eliminating one nozzle and by the use of the swirl stopper, the middle swirl stopper functioning as the middle nozzle takes over and the other two swirl stoppers the necessary force for fixing the Opposing twists in the yarn.
  • the elimination of the middle nozzle affects both the Manufacturing costs of the swirling unit as well as the energy consumption during swirling positive.
  • the absence of the third nozzle has the added benefit of being gentler Yarn treatment.
  • a first preferred embodiment of the device according to the invention is characterized in that that the swirl stoppers are formed by rotatably mounted rollers.
  • a second preferred embodiment of the device according to the invention is characterized in that that the swirl stoppers are aligned with the axes of the nozzles, and that the outer twist stoppers are wrapped in the yarn by at least 90 ° and the medium twist stopper by at least 180 °.
  • a third preferred embodiment of the device according to the invention is characterized in that that the two nozzles impart a twist in the same direction to the yarn.
  • the nozzles can also impart an opposite twist to the yarn.
  • a fourth preferred embodiment is characterized in that the nozzles and the swirling unit having swirl stoppers has a symmetrical arrangement of the nozzles and twist stoppers with opposing nozzles and thread sections of the same length between each nozzle and the swirl stoppers assigned to it.
  • a fifth preferred embodiment is characterized in that each nozzle connects to one individual compressed air supply is connected.
  • the drawing shows a schematic representation of an inventive Air swirling device for one or more staple yarns with elastane or for interlacing two or more staple yarns (without elastane).
  • the swirling device designated by the reference symbol V essentially exists from a plate-shaped carrier 1, from two mounted on the carrier 1 and individual Compressed air lines 2, 2 'fed nozzles 3, 3' and three swirl stoppers 4, 4 'and 5.
  • the Swirling device V is at least one staple yarn F and a second yarn E for swirling fed, the second yarn E an elastane yarn or also a staple yarn can be. If the second yarn E is referred to below as elastane yarn, this should be the case should not be understood as restrictive.
  • Both the staple yarn F and the elastane yarn E are obtained from a supplier, from which only the delivery mechanism 7 for the elastane yarn E is shown.
  • the delivery unit 7 is on the side of the yarn path of the staple yarn F arranged, the supply of the elastane yarn E to the staple yarn F is carried out by means of a deflecting roller 8.
  • the twisting yarn that is created during the intermingling U is led from the swirling device V to a winding 9.
  • the thread running direction is indicated by an arrow A.
  • the nozzles 3, 3 'and the swirl stoppers 4, 4' and 5 are on the carrier 1 arranged symmetrically; the nozzles 3, 3 'lie opposite one another and the thread sections have between each nozzle 3 and 3 'and the swirl stoppers 4, 5 and 4', 5 associated therewith the same length L.
  • the yarn F + E of the intermingling device V fed in the vertical or horizontal direction by 90 ° from its feed direction deflected, whereby a yarn loop is formed, the legs of which by the two Nozzles 3 and 3 'are guided, and then aligned with the feed direction for winding 9 dissipated.
  • the yarn loop with the feed and discharge direction of the Include yarn at an acute angle; it is essential that the wrap angle the twist stop 4 and 4 'is at least 90 ° and is the same size for both twist stoppers.
  • a twist is impressed on the yarn in the nozzles 3 and 3 ', the two nozzles either in the same direction, in the SS or ZZ direction, or rotating in opposite directions, in the SZ or ZS direction, can be trained.
  • the swirl stoppers 4, 4 'and 5 can be rotated by on the carrier 1 stored thread guide rollers are formed, which are aligned with the axes of the nozzles 3, 3 ' are arranged. The latter means that the axes of the nozzles 3, 3 'and the guideways of the yarn around the twist stoppers 4, 4 'and 5 lie in a common plane.
  • the two swirl stoppers 4 and 4 ' serve at the inlet or outlet of the swirling device V. in addition, the swirl caused by the nozzles 3 and 3 ', that from these nozzles to the swirl stoppers runs to block at the swirl stoppers so that it can not continue.
  • the middle Dralistopper 5 sets the necessary rotations in the nozzles 3, 3 ' Counterforce to fix these twists in the yarn. So that's the yarn through the twist imparted to the nozzle 3 between the yarn stoppers 4 and 5 and the twist through the nozzle 3 ' Imprinted twist fixed by the yarn stoppers 4 'and 5.
  • the middle yarn stopper 5 thus acts like a third nozzle, but has the advantage of lower manufacturing costs compared to such a nozzle, lower energy consumption (since no compressed air supply is required) and the gentler yarn treatment.
  • the three yarn stoppers 4, 4 'and 5 have the same diameter, this being about 15 to 30 mm, preferably 22 mm.
  • the vertical Distance from the center of the nozzles 3, 3 'to the axes of the swirl blockers 4, 5 and 4', 5 and thus the length L of the respective thread sections is approximately 25 to 50 mm each and is preferably at 30 mm.
  • a controlled thread insulation for example a plate brake can be provided which increases the clamping force when starting Thread speed reduced and when stopping with decreasing thread speed elevated.
  • the air supply in the compressed air lines 2, 2 'of the thread speed through proportional valves can be optimally adjusted.
  • the support 1 it is also possible to design the support 1 as a wall of a chamber-like air reservoir, which has two compressed air connections for the two nozzles 3 and 3 '. In this case, precautions should be taken be taken that there is a uniform air flow at both nozzles
