Definitions

  • the invention relates to a method for drawing off an endless, synthetic thread according to the preamble of claim 1. This method is known and z. B. in the magazine "Chemical fibers / textile industry” September 1991, pp 1002, 1004, described (see also DE-A 22 04 397).
  • the known method is a single-stage spinning process for producing a multifilament thread, in which the thread is drawn off the spinning nozzle by a delivery mechanism at high speed and then wound up by means of a winding device.
  • the delivery unit consists of two godets, each of which the thread wraps around at 180 °. This means that the thread tension above the godets, starting with the lower take-off tension and up to the godets by air friction and other frictional influences, is continuously increased up to the run-up thread tension with which the thread runs onto the godets. The thread tension is increased so that complete or partial stretching of the freshly spun thread occurs. It is now undesirable and inappropriate to wind the thread on the bobbin with such a high thread tension.
  • the two godets have a shiny, surface hard chrome plating. Thereby, there is between Thread and the godet surface a high friction resistance for kinetic friction and for static friction.
  • spinning take-off machines should require two godets or godets with a laying roller in order to achieve sufficient thread tension reduction and good uniformity (Uster value) of the thread.
  • this process has the disadvantage, in the production of filaments which consist of very thin filaments, that filaments break and that broken filaments are no longer conveyed by the godet, but by which the godet surrounding air flow are entrained and then form a winder on the godet.
  • Thread threading is also very difficult, since here the thread breaks due to the large speed difference. It is also very difficult to set the speeds of the delivery mechanism on the one hand and of the winding device and traversing device on the other. On the one hand, these speeds must be adjustable independently of each other, but they must be adjusted very precisely to one another to prevent tearing or folding (thread tension too low) and there is also the risk of thread damage or business interruption due to tearing or winding.
  • the peripheral speed of the take-up reel must be slightly lower than the peripheral speed of the delivery mechanism. On the other hand, however, it must not be significantly lower than the geometric sum of the peripheral speed of the bobbin and the traversing speed with which the thread is moved back and forth along the bobbin. Finally, the desired thread tensions are difficult and unstable to set in this method.
  • the delivery mechanism can consist of a driven roller, but in particular of two driven rollers, which are arranged one behind the other so that the thread wraps around them with a wrap angle of at least 45 ° in each case.
  • the total wrap angle is in any case greater than 90 °. However, it is clearly below 360 °, preferably below 270 °. Because the delivery mechanism is driven at a circumferential speed that is higher than the thread speed that the thread running onto the delivery mechanism has, there is a speed difference (slip) and thus sliding friction between the surface of the delivery mechanism and the thread. It can now be seen that, in the event of a difference in speed, the coefficient of friction of the sliding friction changes, depending on the amount of slippage, in part by leaps and bounds and is not reproducible.
  • 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 is therefore reproducible.
  • the importance of the invention is to have recognized that this independence is required 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 e.g. B. by plasma coating with metal oxides. It is particularly preferred to also carry out the thread treatment with liquids before they enter 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 feed mechanism is located in front of the traversing triangle, so that the thread is relaxed above the top thread guide, which forms the tip of the traversing triangle.
  • the traversing in which the thread is moved back and forth at high speed transversely to its direction of travel and thereby describes a traversing triangle, causes strongly fluctuating thread tension with, thread tension peaks in the end regions of the traversing.
  • these thread tension peaks add up with the high thread tension that occurs after the thread is pulled off the spinneret during stretching. Therefore, these thread tension peaks cannot adversely affect the quality of the thread.
  • the range of the total wrap angle is preferably specified according to two criteria.
  • One criterion is the sufficient and significant reduction in thread tension, the other criterion is a smooth, trouble-free thread run.
  • the height of the wrap angle also has an influence - albeit not very large - on the height of the minimum value of the slip, which must be specified in order to achieve the same sliding friction behavior as with dry friction. Such limits are specified in claim 2.
  • the speed difference between the running speed of the thread on the delivery unit and the surface speed of the delivery unit must be such that there is sliding friction in every case. It should be taken into account that the thread is not a solid structure when it runs onto the supplying plant, but can adapt to the surface speed of the supplying plant by stretching or shortening. This adjustment must be avoided.
  • the minimum value of the slip will differ from surface to surface of the supply unit on the one hand and from thread to thread on the other hand. However, it has been found that - in the previously examined application cases according to claim 3 - the speed difference, ie the slip, should be set to at least 3%, but preferably to more than 5%.
  • the method according to claim 1 is particularly useful for withdrawing the filaments of a thread from the spinneret at high speed, thereby stretching all or part of it.
  • the delivery mechanism according to the invention has the advantage that no winders are formed on it and that on the one hand high thread tensile forces can be exerted on the thread for stretching, but on the other hand a targeted reduction of thread tension in the winding zone is possible.
  • the use of the delivery mechanism according to the invention is also expedient between such a godet and the top thread guide of the winding zone for reducing the tension in the thread, since with this delivery mechanism it is achieved that the thread with sufficient Thread tension is subtracted from the godet, but the winding is fed with a low thread tension.
  • a heat treatment z. B. is provided by a steam-fed nozzle.
  • a steam-fed nozzle Such a method can be used in particular to produce polyamide threads at high speeds of more than 3500 m / min by rapid spinning, but also polyester threads which in this case are wound at speeds of more than 5000 m / min.
  • a heating pipe in front of the delivery plant, as is the case, for. B. in US-PS (Bag. 1641 or 1584 or 1571, see also US-PS 3,229,330).
  • the method according to this invention is also particularly suitable for the so-called "short spinning".
  • the delivery unit is located at a short distance of less than 2 m below the spinneret.
  • the thread is drawn off by the delivery system so quickly that sufficient cooling takes place over this short distance.
  • the high air resistance that acts on the thread, together with the residual heat remaining in the thread causes the thread to stretch almost completely.
  • the speeds are over 7000 m / min.
  • the first godet in the static friction area works with the advantage of great thread tension reduction.
  • the second godet causes a further reduction in thread tension and an equalization and stabilization of the operating conditions.
  • the process is also particularly suitable for the insertion of the post-treatment processes described after the stretching process. It is therefore between the delivery plant and the head thread guide is proposed a shrinking treatment in which the thread is exposed to heat, and / or a tangle treatment in which an air jet is directed onto the thread transversely to the thread axis, thereby producing a bond between the individual filaments.
  • the method according to the invention is characterized in that reproducible method parameters, in particular thread tensions and thread speed, can be set.
  • reproducible method parameters in particular thread tensions and thread speed
  • cases are conceivable in which maximum accuracy is important, but on the other hand, cases are also conceivable in which, in long-term operation, changes in the surface quality or changes in the thread quality lead to changes in the process parameters and thus also to a change in the thread properties.
  • it is further proposed to regulate the thread tension by adjusting the wrap angle as a function of the measured thread tension.
  • the wrap angle can also be set by the measuring device, in that one of the rollers of the delivery mechanism or another roller, which is arranged upstream of the delivery mechanism, is arranged so as to be movable under the thread tension against spring force in such a way that the wrap angle changes with its movement.
  • a sensor can also be provided with an adjuster, by means of which the relative position of the rollers of the delivery mechanism is changed such that the wrap angle changes.
  • Novel process variants of the short spinning and heating tube spinning already mentioned can be realized with the delivery plant according to the invention. These process variants are the subject of claims 11 and 12.
  • the freshly spun and stretched thread is conveyed through a hot air or steam nozzle into a pitot tube, where it is compressed into a thread stopper.
  • the thread stopper is conveyed through the pitot tube under the impact of the thread and the hot air (steam) and pulled out of the pitot tube as a thread stopper and wound onto a cooling roller. Before the thread plug runs off the cooling roller, the thread plug is pulled off. This leads to considerable thread tension fluctuations. It was therefore difficult to subject the now crimped thread to a uniform tangle treatment, since the thread tension fluctuations also led to different tangle results. The interposition of a usual delivery godet between the cooling drum and tangle nozzle did not help, since the delivery godet transmits the thread tension fluctuations.
  • claim 14 can also be advantageously developed by claims 2 and 3 already described.
  • the thread tension can be further equalized.
  • the embodiment shown in the drawing shows in Fig. 1 and 2 a spinning system for four threads 1, which are wound on a common winding spindle 2 to form a bobbin.
  • the traversing device 3 Before the winding is the traversing device 3, through which each of the threads is guided back and forth along the spool assigned to it.
  • Each of the threads between the fixed top thread guide 4 and the traversing device 3 describes a traversing triangle.
  • the delivery mechanism 7 lies between the collecting thread guides 5 and the head thread guides 4.
  • the collecting thread guides 5 have the Function to reduce the mutual spacing of the threads, which initially corresponds to the pitch of the spinnerets 8, to the pitch of the bobbins on the spindle 2.
  • the delivery unit 7 extends over the total distance of the collecting thread guides 5.
  • the delivery unit 7 consists of two rollers 9 and 10, which are arranged parallel to one another and with a height offset which is exactly the same here as the diameter. This results from FIG. 2.
  • Fig. 1 shows a larger height offset for reasons of drawing, in order to be able to illustrate that there are two rollers 9, 10.
  • the rollers are driven in opposite directions at essentially the same peripheral speed.
  • You are wrapped by the thread with a wrap angle alpha of at least 90 ° and have a low coefficient of friction compared to the thread 1, z. B. 0.2 to 0.6.
  • the peripheral speed is higher, e.g. B. 3% to 30% higher than the thread speed.
  • the thread speed is the geometric sum of the constant peripheral speed of the bobbins and the traversing speed of the traversing device 3.
  • the two godets of the delivery mechanism can be displaceable relative to one another in order to be able to place the thread on the winding head without touching the godets.
  • the godets 9, 10 z. B. on a rotatable bearing plate 17 can be rotatably mounted.
  • the godets can be driven by a motor with a gear connection, but also by two independently controllable motors.
  • the speed of the first godet 9 can thus be set lower than that of the godet 10, so that static friction exists on the godet 9, while on the godet 10 there is significant sliding friction with a slip of 3% or more.
  • FIG. 10 shows a diagram in which the dependency of the thread tension force (F) between the supply unit 7 and the winding, measured in cN, on the slip is shown.
  • the slip here is the difference between the surface speed (v LW ) immediately in front of the feed unit 7 minus the thread speed (v F ) of the feed unit, divided by the thread speed (v F ) mentioned in percent. This applies when the slip is below a certain value. In this area, the relationship between the thread tension and the slip cannot be represented practically and reproducibly, especially if the slip is below one percent. This does result in an essentially reproducible relationship. However, it turns out that the thread tension is dependent on the amount of slip.
  • FIGS. 3 to 9 show a modification of the delivery unit 7.
  • the delivery unit consists of a driven roller 10, to which the thread is fed through a freely rotatable overflow roller 11.

  • Fig. 4 shows a modification of the delivery plant.
  • the delivery mechanism consists of two driven rollers 9 and 10.
  • the first roller 9 is driven precisely at a peripheral speed which is equal to the thread speed (v F ). Therefore, the wrap angle alpha, which is required for the desired reduction in thread tension or thread tension, must be set on the roller 10. It is the roller 10 whose peripheral speed is higher than the thread speed or the surface speed of the preceding roller 9 by the desired slip.
