Definitions
- the invention relates to a method for guiding and swirling a multifilament yarn during melt spinning according to the preamble of claim 1, and to an apparatus for carrying out the method according to the preamble of claim 9.
- a polymer melt is extruded through a spinneret having a plurality of nozzle bores to form stranded filaments. After cooling these very fine filament strands, the filaments are combined to form the synthetic thread.
- the thread is treated, for example, by stretching, relaxing or curling.
- the synthetic thread is wound up into a bobbin. In order to ensure a cohesion of the individual filaments both in the treatment and in the subsequent further processing in the thread, it is known to vortex the multi-thread.
- the thread closing required for further processing is performed by swirling a stretched between two godets piece of thread.
- This can be the thread after expiry of a last galette lead directly to a take-up device.
- the thread tension for swirling advantageously remains unaffected by the winding tension in the thread produced by the takeup device.
- the swirling device is preferably placed in the last thread loop, in order to prevent the stretching tension from being influenced by the tension of the thread and to enable easy handling of the method.
- FDY fully stretched yarns
- individual yarn tensions for swirling can hardly be realized independently of the drawing tension and independently of the winding tension.
- Another object of the invention is to provide a method and apparatus for guiding and swirling a multifilament yarn in which the highest possible number of swirling knots can be produced reproducibly on the yarn.
- the object is achieved by a method having the features of claim 1 and by a device having the features of claim 9.
- the invention has the advantage, in particular when producing fully drawn threads, that the thread tension for swirling remains independent of the draw tension and largely independent of the take-up tension.
- a yarn tension set on a thread piece stretched between the godets is maintained, since the yarn guided on the smooth peripheral regions of the guide shells can essentially not carry out any relative movement to the surface of the guide casing.
- a chucking length of the thread piece is determined by the leadership of the thread piece before swirling and after swirling by a smooth peripheral region, which leads due to their fixed length to a uniform Verwirbelungst with reproducible number of Verwirbelungsknoten.
- the godets for guiding the thread can be formed both by godets with the same guide sheaths or else by godets with guide shunts of different diameters.
- the godets for guiding the thread in a Mehifachumschlingung advantageous by a galette executed with a larger diameter guide sheath and a godet with a smaller diameter guide sheath.
- the godet with a smaller guide sheath in professional circles is also referred to as a so-called Kochlaufrol- Ie or Beilaufrolle.
- the thread tension is preferably adjusted by changing the circumferential speed of the guide jacket, which is upstream of the Verwirbelungseiruichtung. Due to the high adhesion between the smooth circumferential area of the guide jacket, a changed circumferential speed leads directly to an increase or a reduction in the thread tension in the thread section between the two godets. To reduce the yarn tension during swirling, the circumferential speed of the guide casing is slightly increased. In order to obtain a higher yarn tension, the peripheral speed of the godet can be reduced accordingly.
- the development of the invention is particularly preferably used, in which the thread is guided to the expiration of the godets on one of the smooth peripheral regions of the guide shells.
- the smooth peripheral regions are each formed at a free end of the guide shells.
- the guide shells are formed according to a preferred embodiment of the invention with a plurality zonenf ⁇ rmig side by side arranged peripheral regions, wherein in addition to the smooth peripheral region each run a non-smooth peripheral region with a larger average roughness of above 0.2 microns , This makes it possible to realize compensation processes when guiding the thread, without the thread tension being influenced during swirling.
- the yarn in the last loop can be advantageously transported to the outlet from the godet roll over a circumference area of the guide casing which is reduced in diameter. This reduces the circumferential speed of the downstream guide casing, which leads to a reduced thread tension.
- This embodiment of the invention is particularly suitable for being able to wind threads with the lowest possible winding tensions, despite a pre-arranged swirling action.
- the variant of the invention has proven in which the yarn is heated to a temperature of 80 ° C to 25O 0 C before swirling.
- the heating of the thread can be done in principle by any known type of yarn heating.
- at least one of the guide shells is designed to be heatable by a heating device.
- a plurality of threads for example, 8, 10, 12 or 16 threads are usually produced simultaneously in a spinning station.
- the threads are there advantageously parallel juxtaposed and treated simultaneously.
- the development of the invention has proven particularly useful in which the tensioned thread pieces are guided at a distance in the range of 3 mm to 8 mm side by side .
- the Verwirbelungseiniichtung for this purpose preferably has a plurality of thread channels, each forming a distance in the range of 3 to 8 mm between them.
- Each of the thread channels is advantageously associated with at least one arranged on the inlet side yarn guide.
- the support points that are essential for the swirling of a thread can be defined before and possibly behind the swirling device.
- the fiction, contemporary method and the erfmdungs proper device are basically suitable to make in a melt spinning process, a swirling of the yarn or several side by side sensed threads in parallel.
- the inventive method can be integrated into all known spinning processes such as for the production of POY threads, FDY threads, BCF threads or technical threads.

- the guide casing 26 is heated in such a way that the yarn pieces 29 for swirling have a temperature which could be in the range of 8O 0 C to 25O 0 C. It has been shown that, in particular by the swirling of a heated thread, the number of knots per unit length in the thread can be increased.
- Fig. 3 The embodiment shown in Fig. 3 is thus particularly suitable to be arranged as Contestgalette in a drafting field.
- FIG. 4 schematically shows a further exemplary embodiment in the device according to the invention for carrying out the method according to the invention in a view.
- the device has two spaced apart godets 15 and 16.
- the godets each have a guide casing 23 and 26, which are driven by a drive not shown here with a predetermined peripheral speed.
- the guide sheaths 23 and 26 have a smooth peripheral region which exhibits a surface roughness in the range of R a ⁇ 0.2 ⁇ m.
- the threads 11 are thus guided with relatively good adhesion to the guide sheaths 23 and 26.
- a Vewirbelungs worn 22 with a plurality of thread pieces 29 associated thread channels 30.
- Each of the thread channels 30 is assigned to the inlet side Einlauffadenschreiber 32 and on the outlet side a Auslauffadenmony 35. This makes it possible to adjust for the turbulence of between the godets 15 and 16 stretched pieces of thread individual support for swirling.
- Both the inlet yarn guides 32 and the outlet yarn guides 35 can be varied in position, for example to improve the intensity of the swirling accounts.
- inventive method and the device according to the invention are suitable for being able to carry out intensive turbulence in any melt spinning processes for the production of synthetic threads.
