Definitions

  • the invention relates to a false twist crimping machine according to the preamble of claim 1.
  • a false twist crimping machine is known from DE-OS 39 62 182.
  • False twist crimping machines are used to crimp endless thermoplastic threads. Such threads are initially spun as smooth threads. In the false twist crimping machine, a large number of threads are processed in parallel work areas. Each thread is first withdrawn from its bobbin by a first delivery mechanism, then heated in a heating system to approx. 220 ° C., then cooled and passed through a false twister. The thread is withdrawn from the false twist zone by a second delivery unit. The false twist gives the thread a crimp. Crimp values (according to DIN 53840) are 40 - 50%. In many areas of application, however, the aim is to significantly reduce this end-curling behavior. For this purpose, a so-called set heater is used in each work area.
  • This heater is arranged between the second delivery plant and a third delivery plant.
  • the set heater for each thread consists of a heatable tube, in particular an externally heatable one. Steam in particular can be used for heating. This ensures good uniformity from area to area.
  • the effect of the set heater depends on the process parameters of the set zone.
  • the decisive parameters are in particular the speed of the third delivery unit, the temperature of the set heater and its length.
  • a certain lag of the third delivery plant is to be aimed at in order to reduce the thread tension in the set heater.
  • this lag i.e. the speed difference between the second delivery plant and the third delivery plant does not become too large, since otherwise the thread sags and the thread breaks.
  • there is an unstable thread run which leads to so-called voids, i.e. Unevenness in the thread, which later becomes noticeable in the fabric.
  • the object of the invention is to improve and intensify the set effect by appropriately training the set heater.
  • the solution has the advantage that, compared to currently known heater designs, it is possible to work with a considerably increased lag. Furthermore, the temperatures can be significantly reduced with the same set effect, with the result of gentle thread treatment and energy saving. With a heater temperature of approx. 180 ° C, crimping values (e.g. 12%) can be achieved, which in the case of conventional set heaters can only be achieved by temperatures of more than 200 ° C.
  • the actual set heater can be made considerably shorter than before according to this invention. Due to the essentially sealing, preferably seamless connection of the compensating tube, which is from the outside is not heated and - as experience shows - does not have to be insulated, a heat balance can take place within the entire thread cross-section, which in places replaces the previous active thread heating.
  • the connection of the compensating pipe to the heating pipe referred to here as sealing or seamless, does not mean that the two pipes merge into one another without interruption, but that there is no air access at the transition point from one pipe to the other.
  • the crimping machine shown schematically in the figure has a supply spool 10 on which a thermoplastic thread 12 is wound.
  • the thread 12 is drawn off by a delivery mechanism 18 via deflection rollers 14 and 16 under a certain tension.
  • Behind the radiator 20 there is a further deflecting thread guide 22 with which the thread is deflected and fed to a cooling rail 24.
  • Radiator 20 and cooling rail 24 can be aligned approximately roof-shaped to one another, the deflection 22 being in the top of the roof-shaped structure.
  • Behind the cooling rail 24 there is a schematically illustrated false twist sensor 28.
  • This false twist sensor 28 can be designed according to DE-PS 22 13 881 or US-PS 4,339,915.
  • Following the false twist sensor 28 there is a further feed mechanism 30 which serves to pull the thread 12 both over the heater 20 and the cooling rail 24.
  • a set heater which is preferably designed as a curved heating tube 34, which is surrounded by a heating jacket 32.
  • Straight versions of the heating tube 34 are also possible.
  • the heating jacket serves to heat the heating tube 34 from the outside to a certain temperature with steam.
  • the spatial conditions of the false twist crimping machine appropriately, the heating tube 34 and its jacket are preferably arranged upright.
  • a compensating tube 42 connects seamlessly to the heating tube 34, i.e. essentially airtight. It is thereby achieved that the thread 12 transports the atmosphere of the heating tube 34 into the compensating tube 42.
  • a thread guide 44 which is designed as a pin provided with a circumferential groove or as a roller. The groove serves to transfer the thread 12 from the heating tube 34 into the compensating tube 42 with as little friction as possible. It has surprisingly been found that the heated air entrained by the thread 12 from the set heating tube 34 in the compensating tube 42 leads to the fact that the crimp given to the thread 12 in the false twisting zone 28 despite the relatively low temperature, e.g. approx. 160 - 180 ° C, the set heater 42 is further reduced than is possible with known set heaters.
  • a further delivery mechanism 46 Behind it is a device (not shown) which applies a finishing agent to the thread 12.
  • the thread is wound on a take-up spool 50, which is driven by a friction roller 52 on the circumference.
  • a traversing device 54 In front of the friction roller 52 there is a traversing device 54, by means of which the thread 12 is guided back and forth on the bobbin 50 and wound thereon as a cross winding.
  • the false twist crimping machine shown in FIGS. 2 and 3 corresponds completely to the machine according to FIG. 1, to the description of which reference is made.
  • the following also applies:
  • the machine according to FIG. 2 differs from that according to FIG. 1, however, by a mouth 47 provided at the outlet of the compensating tube 42 in the form of a funnel-shaped extension of the tube.
  • the suction nozzle or mouth 48 can be connected to this mouthpiece 47 via conventional connections, e.g. Hoses, suction gun 62 connected to a vacuum source, are drawn in order to pull a thread through the heating tube 34 and the compensation tube 42, as is usually the case at the beginning of a new winding process.
  • the end of the thread 12 coming from the supply spool 10 is drawn in a simple working step to the inlet of the heating tube 34 and then with the gun 62 through both tubes.
  • the thread 12 is then fed to the take-up spool 50 via the traversing device 54.
  • the machine according to FIG. 3 differs from the machine shown in FIG. 2 by another thread threading device.
  • it is a device working with overpressure.
  • a compressed air source 36 via a pipe 40 provided with a valve 37 behind the connection point between heating and Compensating pipes connected to the channel 38.
  • a blast of compressed air is passed through the compensating tube 42 via the channel 38, which triggers a suction effect in the heating tube 34, by means of which a thread 12 held in front of the inlet opening of the heating tube 34 is sucked or blown through the heating and equalizing tube can be.
  • the heating tube 34 corresponds in its dimensions, in terms of diameter and length, to the dimensions of the compensating tube 42.
  • the compensating tube 42 is unheated, but is heated to a certain extent by the warm air entrained by the running thread 12 from the heating tube 34. However, the influence of heat from the inlet to the outlet of the balance tube 42 is continuously reduced, which may contribute to the unexpectedly beneficial effect of the balance tube device.
  • the dimensions of the heating and equalizing tube are the same, except that the heating tube 34 is curved, e.g. B. by a radius between 4 and 10 m, while the compensating tube 42 is substantially straight.
  • the length is in the range between 1 m and 1.5 m, and they have an inner diameter between 3 and 12 mm.
  • the heating tube 34 had a length of 1300 mm and an inner diameter of 4 mm.
  • the compensating tube 42 was 1300 mm long and had an inner diameter of 4 mm.
