Definitions

  • the invention relates to a method and a device for heating a synthetic thread according to the preamble of claims 1 and 19, respectively.
  • a freshly spun synthetic thread (polyester) is conveyed from a spinning zone into a drawing zone by means of a take-off godet and drawn between the take-off godet and a draw godet.
  • the thread is heated in two stages by contact using the heated take-off godet and a directly connected heated metal plate.
  • the fume cupboard is heated to a temperature of 60 to 90 ° C and the metal plate to a temperature of 160 to 200 ° C.
  • the take-off speed is in the range of less than 1,000 m / min.
  • a disadvantage of this method is that the heating of the thread depends exclusively on the contact between the heated surfaces and the thread.
  • the large contact length and the contact force lead to increased thread friction, which adversely affects the thread quality. These effects increase rapidly at higher take-off speeds, so that uniform heat transfer is not possible.
  • the object of the invention is, in the thermal treatment of a running synthetic thread - it can be polyester, but in particular also act polyamide, polytrimethylene terephthalate and polypropylene - to achieve a uniform heating of the thread with a correspondingly uniform stretching and uniform, easily adjustable thread properties.
  • the surface temperature of at least one of the heating surfaces is higher than the melting temperature of the thread material, preferably higher than 100 Kelvin above the melting temperature of the thread material, and that the thread is subjected to a thread tensile force which is necessary for plastic deformation.
  • the high temperature of the heating surface causes a shock-like heating of the thread immediately shortly after entering the heating zone.
  • the so-called stretching point can be localized precisely.
  • the stretch point is a very narrow area of the thread, in which the plastic deformation begins by flowing evenly.
  • the shock-like heating means that structural changes take place preferentially.
  • the frictional mechanical stress on the thread is reduced to a minimum, so that the thread tension, which is required for plastic deformation, has a stable course.
  • a particular advantage lies in the fact that with the continuous stretching and fixing, the thread tension does not need to be increased, but can remain essentially constant. Due to the shock-like heat treatment, a sufficiently good fixing effect is already achieved with the stretching tension. Another advantage is that agents such. B. godets, to increase the thread tension between the individual stages of heat treatment can be omitted.
  • the method variant according to claim 3 can be used advantageously wherever materials are processed, such as. B. polypropylene, which require post-stretching.
  • the process variant according to claim 4 has the advantage that the heat treatment in the first stage can be carried out in particular by means of a heated stretching pin in such a way that, despite the short contact length and high withdrawal speeds, the high surface temperatures cause the stretching point to be formed on the stretching pin.
  • the stretching pin can have a curved surface with a radius of, for example, 10 cm or even much higher. It is fixed and not attached to rotate. His coat is partially touched or wrapped in the thread. Due to the high surface temperatures, the contact length and the contact force can be kept very small. This reduces wear on the stretching pins. In addition, there are very low frictional forces on the thread, so that thread damage is avoided.
  • the stretching pin can also be replaced by a plate which is touched by the thread.
  • the invention deliberately turns away from the "only" contact-free thread guide.
  • the heat transfer takes place in the first stage by contact, which is designed so that there are only low frictional forces on the thread.
  • the first stage of the heat treatment can in particular be carried out by means of a hot godet through which the thread is drawn off the spinneret. This godet lies at a point where the freshly spun thread has cooled down considerably (approx. 40 ° C). This godet can be heated to a temperature of 70 to 120 ° C.
  • a subsequent stretching godet the thread is drawn off from the first godet with such a thread tension that immediately when the Thread from the godet forms the stretching point.
  • a draw pin or a heated plate can be used to replace the extraction godet.
  • the contact length on the stretching pin is so small that the resulting frictional forces are just sufficient for the first time that flow occurs on the stretching pin and a stretching point is accordingly formed.
  • the thread is guided essentially without contact, ie with very precise guidance at a close distance to a heating surface which is heated to a temperature between 350 and 550 ° C.
  • the distance between the thread and the heating surface is in the range of 0.5 to 3.5 mm, so that the thread is heated in a shock-like manner when it enters the heating zone.
  • the thread is guided by thread guides, which on the one hand ensure that the thread runs smoothly, and on the other hand also ensure the exact distance to the heating surface.
  • the thread can then also be guided contact-free and at a close distance from another heating surface which is heated to a temperature between 300 and 500 ° C.
  • the embodiment according to claim 8 allows a very precise adjustment of the draw ratio.
  • the directly heated stretching pin reliably leads to the formation of the stretching point even at take-off speeds above 5,000 m / min.
  • the method variant according to claim 9 has the advantage that larger wrap angles are possible to generate high thread tension.
  • the method modification according to claim 11 offers the advantage that the entrained spinning heat can already be used in the first stage of the heat treatment. It is not necessary to guide the thread over a curved heating surface. With this, take-off speeds in the range of 6,000 to 7,500 m / min can be achieved.
  • the process variant according to claim 14 has the advantage that the thread forms a precisely localized stretching point at low drawing tension and undergoes a preferred structural transformation in the first step of drawing due to the shock-like heating.
  • the process can be applied to all common types of polymer. It can be advantageous for the mechanical properties of threads that they are spun from a formulation of different polymers. For example, it is known that the addition of up to 5% PBT (polybutylene terephthalate) to PET improves the spinnability and the elastic properties of the fibers.
  • PBT polybutylene terephthalate
  • This process can preferably be used to process polypropylenes with a narrow molecular weight distribution in the range less than 3, in particular types made from a metallocene base.
  • the device is characterized in that a very short heating device is made possible, but on the other hand, due to its design, it has the advantage that a very specific temperature control in the thread, which is matched to the speed of the thread, and a very uniform heating over the length of the thread is made possible.
  • the shock-like supply of heat when the flow begins prevents the crystal structure from being disturbed and thus enables optimal orientation of the thread molecules.
  • the development of the device according to claim 22 has the advantage that it can be operated easily, in particular that the thread can be easily inserted. Monitoring is also possible.
  • the embodiment according to claim 23 ensures a smooth thread guide and also allows a temperature control adapted to the needs. In this way, the strength, extensibility and tendency to shrink of the thread can be influenced to a very large extent and set to the desired values.
  • the embodiment according to claim 24 serves to fix the thread path relative to the heated surface but also to calm the thread path.
  • the embodiment according to claims 25 and 26 is shown in a simple mechanical manner.
  • the wrapping of the thread on the stretching pin can be adjusted very simply by positioning the stretching pin in such a way that, taking into account the temperature of the stretching pin, the thread tension is increased to such an extent that the stretching point is formed on the stretching pin.

  • the pump 9 conveys the melt flow to the heated spin box 10, on the underside of which the spinneret 11 is located.
  • the melt emerges from the spinneret 11 in the form of fine filament strands 12.
  • the filament strands pass through a cooling shaft 14.
  • an air flow 15 is directed transversely or radially onto the filament sheet 12 by blowing. This cools the filaments.
  • the filament sheet is combined into a thread 1 by a preparation roller 13 or a preparation pin and provided with a preparation liquid.
  • the thread is drawn out of the cooling shaft 14 and from the spinneret 11 through a take-off godet 16.
  • the thread wraps around the take-off godet 16 several times.
  • an overflow roller 17 is arranged which is crossed over to the godet 16.
  • the overflow roller 17 is freely rotatable.
  • the godet 16 is driven by the godet motor 18 and frequency transmitter 23 at a presettable speed. This withdrawal speed is many times higher than the natural exit speed of the filaments 12 from the spinneret 11 and higher than the filament speed after solidification in the blowing.

On the one hand, they contribute to a calming of the thread running and a heating of the thread by running contact, and on the other hand they have only a slight friction on the thread due to the low looping. The important thing, however, is the contact-free guidance in close proximity to the highly heated heating surface.
