Definitions

  • the invention relates to a method for false twist texturing of a synthetic Thread to a crimp yarn and the crimp yarn.
  • a curling yarn is produced, which is a very uniform structure with a low bulk.
  • the filaments on the drawing pin become a relatively closed filament composite created a low bulk and thus a low fullness of Curled gams.
  • the crimped yarns produced in this way receive a more artificial look.
  • the object is achieved according to the invention by a method with the features Claim 1 and a crimped yarn with the features of claim 8 solved.
  • the method according to the invention is based on the finding that the setting the thread tension in the drawing zone in front of the drawing pin an immediate Influences the uniformity of the stretching. So it was found that with particularly low thread tensile forces the thread during the run-up on the stylus is excited to vibrate, which leads to an uneven thermal stress on the thread on the drawing pin and thus to an uneven Stretching the thread leads.
  • the effects are used, that the evaporating volatile constituents of the thread on emergence exert forces on the hot straightening pin which are proportional to the low thread tension acting transversely to the thread running direction and a swinging movement of the thread on the drawing pin.
  • the uneven stretching and uneven thermal stress on the thread has an effect the false twist texturing in the false twist zone such that the synthetic Filaments are so unevenly intertwined that they alternate Thread pieces with a loose filament waistband and thread pieces with a closed filament waistband are present.
  • the loose filament band forms a larger thread cross-section than the fixed filament bundle, so that a Crimp yarn with a thick-thin effect is created.
  • the synthetic thread is fed to a heated stretching pin in a stretching zone with a delivery speed w 1.1 and a low absolute thread tension F 1 of at most 5 cN.
  • the thread is drawn in the drawing zone by wrapping the drawing pin with a wrap angle ⁇ ⁇ 270 ° and drawn off by a downstream delivery mechanism, the thread tension F 2 in the thread path behind the drawing pin being significantly greater than the thread tension F 1 in front of the drawing pin.
  • the thread is fed into the false twist zone by the feed mechanism at a feed speed w 1 , the feed speed w 1 being greater than the delivery speed w 1.1 for stretching the thread in the draw zone.
  • the false twist is fixed at a temperature of over 180 ° C.
  • the thread is then slightly stretched in the false twist zone, but the take-off speed w 2 is not greater than 1.1 times the feed speed w 1 .
  • the crimped yarn is then wound up into a bobbin.
  • the method variant according to claim 2 has proven particularly useful.
  • the thread tension F 2 is set in the range from 0.5 cN / dtex to 1.2 cN / dtex in front of the delivery mechanism for pulling the thread out of the drawing zone.
  • the drawing pin is in the range when the thread is stretched to a temperature heated from 80 ° C to 160 ° C, preferably above 100 ° C, the thread Wrapping pin partially wrapped with a wrap angle in the range of at least 90 °. This has an influence on the crystallinity of the filament strands, so that the differences in the filament composites have a high stability.
  • post-stretching is carried out in the false twist zone of the thread.
  • setting of post-stretching according to the method variant according to claim 5 particularly advantageous.
  • the process variant is used to produce less highly elastic crimp yarns proposed according to claim 7.
  • the thread after the False twist generation and before winding to the coil by heating post-treated so that the thread can shrink.
  • the process according to the invention enables the production of a crimped yarn possible, which has properties that are otherwise only known from fancy yarns are.
  • the natural character of the crimped yarn according to the invention becomes due to the irregular changes in the sequence and size of the filament bundles particularly reinforced.
  • the uneven thread cross section of the invention Crimped yarn occurs especially when dyeing the filament yarn or even stronger with a fabric made from it forth. Not only that the thread pieces with the open filament band one have completely different color rendering than the thread pieces with closed Filamentbund, but have the thread pieces with closed filament bundle also a higher crystallinity than the thread pieces with an open filament band. A structured dyeability is thus achieved, that in a flat structure leads to a uniform color structure.
  • the different pieces of thread can range from a few millimeters to several centimeters have.
  • Such crimped yarns can be opened with a filament waistband due to the thread pieces advantageous to a composite thread from several individual threads produce different polymers, for example.
  • This is the procedure proposed according to claim 11.
  • At least one of the threads is in front of the Connecting to the composite thread according to the invention textured according to the method steps according to claim 1.
  • the composite threads thus produced stand out also characterized by a natural character.
  • the threads are connected preferably by air swirling using a swirling nozzle. there an air jet is directed essentially across the bundle of threads, so that intertwine the filaments of the threads.
  • the device has been used to produce the crimped yarn according to the invention with the features according to claim 14 particularly proven.
  • the Device a supplying plant, a drawing pin, a first supplying plant, a heating device, a cooling device, a false twister, a second delivery plant and a winder.
  • a thread guide in Thread run downstream of the straightening pin, which for setting a predetermined
  • the wrap angle of the thread is designed to be adjustable on the stretching pin is. This allows the characteristic uneven stretching on Drawing pin by changing the wrap of the thread within wide limits to adjust.
  • the thread guide is preferably adjusted on a guideway with a is formed substantially constant distance from the circumference of the stretching pin.
  • the thread tension forces set in the drawing zone thus remain essentially unchanged even when changing the wrap angle on the stretching pin.
  • FIG. 1 an embodiment of the device according to the invention for performing the method according to the invention is shown schematically.
  • the device has a feed unit 17 which draws a multifilament thread 4 from a supply spool 1 via a head thread guide 15.
  • the feed unit 17 is driven in such a way that the thread 4 is guided into a drawing zone at a delivery speed w 1.1 .
  • a heated stretching pin 18 is arranged within the stretching zone, which extends between the supply unit 17 and a downstream supply unit 2.
  • the stretching pin 18 is heated to a surface temperature in the range from 80 ° C to 160 ° C.
  • the stretching pin 18 is wrapped by the thread 4 with a wrap angle in the range of at least 90 °.
  • a thread guide 19 is arranged on the outlet side of the stretching pin 18.
  • the thread guide 19 can be adjusted in a guide 20 essentially parallel to the stretching pin in such a way that a wrap angle ⁇ of 90 ° to 270 ° can be set on the stretching pin. After setting a wrap angle, the thread guide 19 is fixed in its respective position, so that the thread wrap on the stretching pin remains unchanged during the process.
  • the heating device 5 is designed such that the thread is heated to a temperature in the range from 180 to 200 ° C.
  • the heating device can have a heat transfer fluid which heats a heating surface contacted by the thread.
  • the heating device it is also possible for the heating device to be electrically heated at a temperature above the melt temperature of the thread material. In this case, the thread is guided at a distance from the heating surface.
  • the heating device 5 is followed by the cooling device 6, by means of which the thread is cooled to a temperature of approximately 80 to 100 ° C.
  • the cooled thread passes through the false twist sensor 7.
  • the thread 4 is then drawn out of the false twist zone by the second delivery mechanism 3 at a take-off speed w 2 .
