Definitions

  • the invention relates to a method for pulling a endless, synthetic thread according to the generic term of Claim 1 or according to the preamble of claim 14. These methods are known. The first is e.g. B. in the Magazine "chemical fibers / textile industry” September 1991, S. 1002, 1004, described (see also DE-A 22 04 397).
  • the known process is a one-step spinning process for the production of a multifilament thread in which the thread through a delivery plant at high speed from the Spinneret withdrawn and then by means of a winding device is wound up.
  • the delivery plant exists from two godets, each of which the thread wraps at 180 °. This means that the thread tension is above the Godets, starting with the lower trigger voltage and to the godets due to air friction and other frictional influences is continuously increased up to the bobbin thread tension, with which the thread on the godets accumulates. The thread tension is increased so that a total or partial stretching of the freshly spun Fadens occurs.
  • these speeds have to be independent be adjustable from each other, but they must Tearing or swapping (thread tension too low) to prevent it from being adjusted very precisely and there is also a risk of thread damage here or business interruption due to tearing or winder formation.
  • the peripheral speed the take-up spool may be slightly lower than that Circumferential speed of the delivery plant.
  • it may but not be significantly lower than that geometric sum of the circumferential speed of the coil and traversing speed with which the thread runs lengthways the spool is moved back and forth.
  • the same Effect can be achieved in that the thread first via a traversing device, then via a smooth roller that with higher peripheral speed than the take-up spool can rotate, and then over a guided second traversing device and fed to the coil becomes. Because a smooth roller is used and wrapping at 180 ° is the danger at Winder formation also exist here and there are also here the difficulty in putting on the thread. Even with the Setting the roller relative to the speed setting of coil and traversing device it holds very precisely.
  • a winding machine is known from EP 00 16 942 A1, in which a rotationally driven grooved roller, which partially wraps around the thread, is arranged between the traversing device and the winding spindle in order to reduce thread tensions, in particular the thread tension fluctuations induced by the thread traversing device during winding of the thread - And speed adjustable.
  • the wrap angle of the thread on the grooving roller can be adjusted by the change in position in such a way that the thread slides on the thread guide surfaces of the grooving roller at a predeterminable speed difference between the thread speed and the peripheral speed of the grooving roller.
  • the known arrangement allows thread tensions and thread tension fluctuations to be reduced shortly before the thread is fixed on the spool, so that the spool structure and the quality of the spools are improved.
  • the delivery unit can consist of a driven roller, in particular but consist of two driven rollers that are arranged one behind the other so that the thread with them a wrap angle of at least 45 ° each wraps around. So the total wrap angle is anyway greater than 90 °. However, it is well below 360 °, preferably below 270 °. Because the delivery plant is driven at a peripheral speed, which is higher than the thread speed that the on the Has accumulating thread exists between the Surface of the delivery mechanism and the thread a speed difference (Slip) and thus sliding friction. It now shows that in the event of a speed difference the coefficient of friction of the sliding friction changes Dependent on the amount of slip, sometimes erratic and not reproducibly changes.
  • the friction behavior of a body with dry sliding friction is characterized in that the sliding friction coefficient is smaller than the static friction coefficient and furthermore the sliding friction coefficient is independent of the speed.
  • the resistance force that acts on a moving body is independent of the speed and therefore reproducible.
  • the importance of the invention is to have recognized that this independence is necessary for a slip delivery plant, by means of which the thread tension is to be reduced, and also that there is a slip area in such a delivery plant in which this independence exists.
  • the surface is designed so that it has a low coefficient of friction compared to the thread.
  • the surface is therefore by no means smooth or shiny, but rather rough or matt.
  • Wear-resistant surfaces of this type can, for. B. by plasma coating with metal oxides. It is particularly preferred to also carry out the thread treatment with liquids before entering the delivery plant in such a way that the coefficient of friction is low. A coefficient of friction of 0.2 for slip friction is desirable.
  • the range of the total wrap angle becomes after two Criteria preferred.
  • One criterion is the sufficient one and significant reduction in thread tension, the other criterion is a smooth, trouble-free thread run.
  • the height of the wrap angle also has a - but not very big - influence on the Height of the minimum value of the slip, which is specified must have the same sliding friction behavior as with to achieve dry friction. Such limits are in Claim 2 specified.
  • the speed difference between the run-up speed of the thread on the delivery mechanism and the surface speed the supplying plant must be that there is sliding friction in every case. It is too take into account that the thread when running onto the The delivery plant is not a fixed structure, but rather through itself Stretching or shortening the surface speed of the Can adjust delivery plant. This adjustment must be avoided become.
  • the minimum value of the slip is from surface to the surface of the delivery plant on the one hand and from thread to Thread on the other hand may be different. It has however, it emerged that - in the previously examined Use cases according to claim 3 - the speed difference, i.e. the slip to at least 3%, but preferably set to more than 5% should.
  • the method of claim 1 is particularly useful to the filaments of a thread at high speed of the spinneret and pull it off completely or partially stretch.
  • the delivery plant according to the invention has the Advantage that no winders are formed on it and that on the one hand high thread tensile forces for stretching on the Thread can be exercised, but on the other hand a more targeted Thread tension reduction possible in the winding zone is.
  • Tangled nozzle In this is an air jet blown across the thread direction and thereby the formation of individual ones distributed over the yarn length Knots causes. This creates cohesion the individual filaments in the thread improved.
  • the method according to this invention is particularly suitable also for the so-called "short spinning". It will Delivery plant at a short distance of less than 2 m arranged below the spinneret. The thread is through the delivery plant is withdrawn so quickly that sufficient Cooling takes place over this short distance. At the same time the high air resistance that acts on the thread causes together with the residual heat remaining in the thread an almost complete stretching of the thread. The speeds are over 7000 m / min.
  • the surprising discovery underlying this invention is that when the slip increases Values not previously practiced that are above 2%, preferably but more than 3%, the thread tension change after the godet or after the delivery plant no longer from is dependent on the surface speed of the godet. Therefore, this method is very stable in operation possible because of the inclination of the delivery plant due to filament breaks and / or winder formation for a business interruption is practically eliminated.
  • the high of Thread tension on the other hand, is changed with the wrap angle alpha clearly and stably defined. As a result of the height of slip is also the risk of winder formation at the delivery plant despite the low thread tension, with which the thread runs from the delivery plant, eliminated. So it can be a very strong stress relief occur.
  • the first godet works in the field of static friction with the advantage of great thread tension reduction.
  • the second godet causes a further reduction in thread tension and an equalization and stabilization the operating conditions. Because of the strong stress relief the method is particularly suitable for Insertion of the post-treatment procedures described the stretching process. It is therefore between the delivery plant and shrinking the head thread guide proposed where the thread is exposed to heat and / or a tangle treatment in which an air jet directed at the thread transverse to the thread axis and thereby a bond between the individual filaments will be produced.
  • the wrap angle can be set by one of the rolls of the delivery plant or another roll, which is upstream of the delivery plant, such under the Thread tension is arranged to be movable against spring force, that the wrap angle changes with their movement.
  • a sensor can also be provided with a Adjuster by which the relative position of the Roles of the delivery plant is changed so that the Wrap angle changes.
  • the freshly spun and stretched thread through a hot air or steam nozzle into a pitot tube promoted and compressed there to a thread plug.
  • the thread plug is under the impact of the thread and the hot air (steam) is conveyed through the pitot tube and pulled out of the pitot tube and wound onto a cooling roller. Before the thread plug runs off the cooling roller the thread plug is released. This leads to considerable Thread tension fluctuations. It was therefore with Difficulties connected, the now curled thread subject to an even tangle treatment, because the thread tension fluctuations too different Tangle results led. Also interposing one usual delivery godet between cooling drum and tangle nozzle brought no remedy, since the supply godet the thread tension fluctuations transmits.
  • claim 14 also advantageous due to the features of the claims already described 2 and 3 can be trained, because those in these Range specified for the total wrap angle a and those available at the supplying plant Slip can also be advantageous on the from Use thread stopper with the textured thread removed.
  • a thread brake between the The delivery plant and the Tangled nozzle can be used to further homogenize the thread tension.

  • the godets can by a motor with gearbox connection, but also be driven by two independently controllable motors.
  • the speed of the first godet 9 can thus be lower than that of the godet 10 can be set so that at the godet 9 static friction, on the godet 10, however significant sliding friction with a slip of 3% or more consists.
  • FIG. 10 shows a diagram in which the dependence of the thread tension force (F) between the supply unit 7 and the winding, measured in cN, on the slip is shown.
