Definitions

  • the invention relates to a method and a device for the treatment of filament yarn in a yarn duct of a nozzle, with supply of the blowing medium in the yarn channel.
  • Endlösfilamentgarn has two main tasks.
  • the yarn made of industrially produced filaments, should be given a textile character and also textile-technical properties.
  • the yarn is treated for specific quality characteristics for further processing and / or for the final product. Part yarn qualities must be produced which are not necessary and unavailable in the products made with natural fibers.
  • the application areas are in the industrial processing of. Textiles, e.g. for the construction sector, the automotive industry, but also for carpet production and for special textile products in the sports and leisure industry.
  • spun yarn is to be treated by certain preparations for the best possible industrial processing and the processing process for yarns and fabrics to be optimized. Optimization here also means maintaining or increasing certain quality criteria and reducing production costs, including in terms of downtime throughout the entire process.
  • the yarn is provided with protective substances immediately after the spinning process or the production of individual filaments.
  • the protective substances should be an aid for subsequent processing.
  • the substances used for the preparation give oelige sliding property, so that the sliding friction of the yarn throughout the way the processing remains as deep as possible, the risk of damage or a Gambruches reduced and the abrasion of the sliding surfaces of the transport and processing plants as small as possible can be kept. But there are a whole series of other factors that are favorably influenced by the preparation or the preparation, such as static charges. A wide area is the protection against püzbefall of the yarn during, the storage times between the different stages of processing.
  • DE 41 02 790 deals with a special problem with false twisting crimping machines and proposes a delivery nozzle.
  • the conveying air is for this purpose at an angle of e.g. 20 ° to the Garnläufraum blown into the nozzle channel. With the almost exclusive conveying effect, the yarn remains virtually unchanged.
  • US Pat. No. 4,214,352 proposes a texturing nozzle for the production of a looping yarn. An injection angle of approx. 45 ° is shown.
  • the aim was to make the connection even at the highest speeds of yarn transport immediately after the spinneret and e.g. directly in connection with the application of spin finish of e.g. 3'000 - 7'000 m / min. It was part of the task to improve the conditions for the treatment of yarn with regard to preparation agents, the productivity, in particular the yarn quality, even at the highest speeds.
  • the method according to the invention is characterized in that the blowing medium is directed slightly in the thread running direction and introduced into the yarn channel at an insertion angle with an angular deviation .alpha. From the perpendicular to the thread running direction greater than 15.degree., But smaller than 45.degree., Without the filaments of the prepared yarn Generation of. Knots are mixed and easily crossed.
  • the inventive device is characterized in that the device is designed as a migration nozzle, with a directed in Garnlaufraum pressure medium supply channel in the yarn channel, which with an angular deviation ⁇ from a perpendicular to Garnlaufraum or to the longitudinal center axis of the Garnkanales greater than 15 ° but less than 45 ° in the yarn channel is directed.
  • the invention further relates to the use of the device for a thorough mixing and uniform distribution of spin finish on filament yarn, whereby the filaments are connected to a slightly crossed but knot-free yarn and at the same time the spin finish is distributed more optimally on the whole yarn.
  • the new solution fulfills a dual function, namely the crossing and the optimization of the spin finish and its distribution. Characterized in that the air flow is given a strong conveying effect in Garnlaufraum, not only the transport speed of the yarn can be increased, but the effect of the air, in the sense of intense air vortices, be increased without the generation of knots.
  • the practice can be provided by a new element with very positive effects, which were previously not possible in this way, and allows a variety of applications. In the majority of applications air is the optimal blowing medium. It turns out, however, that in particular applications, steam is also usable as a medium, e.g. for relaxing.
  • the new process stage is referred to as the migration stage and the new air nozzle as a migration nozzle.
  • a pressure of about 0.5 bar has been found to be optimal.
  • the closest technique is swirling. In the swirling a mixing and connection of the individual filaments of a yarn is sought, which is recognizable as a result by visible nodes.
  • no nodes should be formed, which is achieved on the one hand by an injection angle of greater than 15 °, preferably 20-60 °, particularly preferably less than 45 ° and on the other hand with a lower pressure of the treatment air.
  • the air jet directed in the yarn running direction has a sufficiently intensive distribution and mixing function for the spin finish in the yarn duct.
  • the spin finish is distributed much more evenly throughout the yarn by means of the swirling flow and the very intense movement of the filaments relative to each other by local spinning and rubbing movements of the filaments and, with the quite good bonding effect for the filaments of a yarn, gives a visibly more stable yarn path even at the currently highest transport speeds for the yarn.
  • the said skipping was no longer found after the use of the new solution, so that the risk of yarn breakage can be significantly reduced.
  • the treatment in the migration nozzle takes place in the context of the spinning process, preferably immediately after the preparation, at very high transport speeds of the yarn.
  • the migration nozzle has a continuous and in many applications extending in the thread running direction treatment channel with a directed in the transport direction compressed air supply into the yarn channel, which opens with a deviation from a vertical greater than 15 in the yarn channel.
  • the migration nozzle is placed at a free distance immediately after a spin agent application device.
  • the effective yarn channel length is preferably formed continuously widened with the smallest cross section in the region of the yarn feed and the largest cross section in the region of the yarn take-off from the yarn channel of the migration nozzle.
  • the previous experiments have shown that good results are achieved when the ratio inlet cross section to outlet cross section is about 1: 2.
  • the air supply leads in at the end of the first third of the treatment channel.
  • the migration nozzle has a threading slot over the length of the yarn channel. This is preferably arranged in the upper third of the Garnakanels in the parting plane between the nozzle plate and baffle plate.
  • the migration nozzle can be designed as a simple, double or multiple nozzle.
  • the same or a slightly modified nozzle can also be used for retaxation, where steam is needed instead of compressed air.
  • the nozzle can be closed or open. Nozzle can be used with threading slot.
  • the connecting means are preferably arranged in a common orientation, preferably in alignment with the yarn run. Surprisingly, it could be determined with a corresponding pin connection that, compared to the prior art, the entire nozzle body can be built much smaller, as it were in miniaturized form.
  • the pitch between two adjacent yarn runs is much smaller selectable than before. In some applications, this even has a repercussion on the size of the godet.
  • On one and the same machine size Due to the possibility of miniaturization, thanks to the new connection, additional yarn runs can be provided and accordingly the overall performance of the machine can be increased. This means that the otherwise rather used in the watch technology fasteners on completely different levels brings unexpected benefits.
  • the powerful cohesion of the parts can be ensured as in the prior art by a classic screw connection.
  • the new solution is particularly advantageous when used as Verwirbelungsdüse and as a thermal treatment body and, as will be shown, as a migration nozzle ..
  • the treatment medium is directed as precisely as possible to the longitudinal center axis of the yarn channel, but with a slope greater than 15 ° in the yarn transport direction. This produces uniform vortices on both sides but no nodes.
  • FIG. 1 shows a detail of a yarn treatment stage 1, wherein on the left the chemical preparation stage 2 and on the right the migration stage 3 are shown.
  • the yarn 4 comes directly from a spinning process and is guided over a preparation device 5, which has a main body 17 in which a feed channel for the preparation agent CH.Pr is guided from below into the area of the thread run and ends with the so-called preparation lips 7.
  • a preparation device 5 which has a main body 17 in which a feed channel for the preparation agent CH.Pr is guided from below into the area of the thread run and ends with the so-called preparation lips 7.
  • U-shaped two guide webs 8 are arranged, which guide the yarn 4 laterally over the preparation lips 7.
  • the main body 17 preferably has a curved guide groove 9, such that the yarn path is forcibly guided over the point of contacting the yarn 4 with the preparation means CH.Pr.
  • the order of the preparation agent CH.Pr on the yarn 4 is carried out in the manner of a Mitreiss bines by sliding contact. Because the preparation CH.Pr in the feed channel 6 is under pressure only to the extent that a safe Nachfliessen is guaranteed, it is not possible to uniformly wet all the filaments of the yarn. The result is that the yarn 4 can not be homogeneously provided with the spin finish on the preparation lips 7. Depending on the nature of the preparation agent, the spin finish film, which is partly applied on one side, dries rapidly, so that the effectiveness remains reduced.
  • this problem can be overcome by subjecting the yarn 4 to a more intense swirling air flow in a migration nozzle 10 at a distance FA shortly after preparation.
  • a double vortex flow has proven to be optimal, which produces a good mixing of the preparation agent in the entire yarn composite and at the same time a crossing of the filaments in the yarn 4 '.
  • swirling nodes FIG. 6c
  • the yarn is opened by the double vortex flow and the individual filaments are slightly crossed against each other (see Figure 6b).
  • a migration nozzle 10 is again shown in section on a larger scale in FIG. 2a.
  • the migration nozzle 10 is formed in two parts and consists of an upper cover plate or baffle plate 11 and a lower nozzle plate. 12 with the connection 13 for the treatment medium. From the port 13, the medium via a first bore 14 and a Druckmediumzuf mulkanal 15 is guided in the yarn channel 16. Important here is the blowing direction, which is designated by the angle ⁇ .
  • the angle ⁇ must be greater than 10 ° to a vertical with respect to the Garnlauf in the yarn channel 16. According to previous experiments, the angle ⁇ should be even greater than about 15 °.
  • the angular range of 15 ° - 60 ° still produces a double vortex, but at the same time a strong conveying effect in the yarn transport direction.
  • the mouth of the Druckmediumzu technologicalkanales 15 is located approximately at the end of the first third of the Garnkanales 16, as can be seen from the measures X and Y.
  • the free cross section of the yarn channel 16 in the yarn transport direction becomes increasingly larger.
  • the size of the narrowest cross section depends on the denier of the yarn, as is already known with swirl nozzles.
  • the area F3 is approximately twice as large as F1, depending on the angle, F2 proportionally proportional between the two values F1 and F3.
  • the migration stage 3 works with a gaseous medium. It may be mere compressed air, heated air or steam, depending on the nature of the intended treatment.
  • a free distance FA between the preparation device 5 and the migration nozzle 10 is of great advantage for the subsequent installation of a migration nozzle in existing plants.
  • the gaseous medium used in the migration nozzle 10 should act at least predominantly in Gamtransportides, such that as little as possible of the gaseous medium in the inlet region 20 of the yarn channel 16 blows back and thereby disturb the order of the chemical preparation agent CH.Pr.

  • Each flow chamber has a yarn inlet 38, a fermentation outlet 39 and in the middle region a medium supply opening 15. If the medium is hot steam, the yarn transport speeds that are very high today result in a disadvantage for the yarn that has been treated with preparations at some point before, for extremely aggressive conditions.
