Abstract

A method and device for producing melt-spun continuous threads, whereby a thread is initially prepared according to a method known per se and subsequently compacted in order to obtain a closed threadline. A large amount of compressed air is consumed during compacting and part of the preparation agent is expelled from the thread by the compressed air and atomized. The novel method provides for a closed threadline and dispenses with the disadvantages mentioned in association therewith. Two preparations are used at a distance from each other in order to provide good thread properties during the production process. A partial amount of the preparation agent is deposited thereon. A first preparation occurs upstream from a first unwinding element. A second preparation occurs downstream from said first unwinding element, resulting in greater cohesion of the filaments in said threads. The invention is used in the production of synthetic fibers.

Description

Die Erfindung betrifft ein Verfahren zur Herstellung von schmelzersponnenem endlosem Mehrfarbengarn gemäß dem Oberbegriff des Anspruchs 1 sowie eine Vorrichtung zur Durchführung des Verfahrens gemäß dem Oberbegriff des Anspruchs 5.The invention relates to a method for producing melt-spun endless Multi-color yarn according to the preamble of claim 1 and a device for performing the method according to the preamble of claim 5.

Bei der Herstellung von schmelzersponnenen Endlosfäden besteht das Problem, daß die Fäden, die nicht weiter behandelt werden, beim Abziehen und Verstrecken auf den Galetten aufspleißen, daß heißt, die einzelnen Filamente laufen auseinander und einzelne Fäden vermischen sich untereinander. Hierdurch werden die Laufruhe des Fadens, die maximal mögliche Belegung einer Galette und bei mehrfarbigen Fäden die Klarheit der einzelnen Farben negativ beeinflußt.The problem with the production of melt-spun continuous filaments is that the threads that are not further treated, when pulling and stretching on the Splicing off godets means that the individual filaments diverge and individual ones Threads mix together. This will make the Thread, the maximum possible occupancy of a godet and, for multi-colored threads, the Clarity of the individual colors is negatively affected.

Die DE 196 49 809 A1 beschreibt ein Verfahren zum Spinnen, Verstrecken und Aufspulen eines synthetischen Fadens, bei dem der Faden einer Wärmebehandlung unterworfen wird. Vor der Wärmebehandlung erhält der Faden eine Vorpräparation und nach der Wärmebehandlung eine Nachpräparation. Das Verfahren ist nicht für gekräuselte mehrfarbige Garne einsetzbar.DE 196 49 809 A1 describes a method for spinning, drawing and winding a synthetic thread in which the thread is subjected to heat treatment is subjected. Before the heat treatment, the thread receives a preparation and a post-treatment after the heat treatment. The procedure is not for crimped multi-colored yarns can be used.

Aus der EP 0 485 871 B1 sind ein Verfahren und eine Vorrichtung bekannt geworden, wobei unterschiedlich gefärbte Teilfäden nach einer Präparation einzeln vorkompaktiert, vereinzelt auf Galetten verstreckt und anschließend gemeinsam texturiert, kompaktiert und auf einer Spule aufgewickelt werden, wobei die Vorkompaktierung während des Verstreckens wieder rückgängig gemacht wird. Durch das Vorkompaktieren soll erreicht werden, daß die Teilfäden einen gewissen Zusammenhalt während der Verarbeitung haben und das fertige Garn klar unterscheidbare Farben aufweist.A method and a device have become known from EP 0 485 871 B1, differently dyed partial threads individually precompacted after preparation, occasionally stretched on godets and then textured and compacted together and wound on a spool, the pre-compaction during of the stretching is reversed again. By precompacting should be achieved that the part threads a certain cohesion during the Have processing and the finished yarn has clearly distinguishable colors.

In der EP 0 784 109 A2 sind ein Verfahren und eine Vorrichtung zur Erzeugung eines mehrfarbigen Garnes beschrieben, bei dem unterschiedlich gefärbte oder anders anfärbende Teilfäden so behandelt werden, daß vor einer endgültigen gemeinsamen Kompaktierung die Teilfäden wieder vereinzelt, einzeln einer weiteren sogenannten Nachkompaktierung unterworfen, zusammengeführt, kompaktiert und aufgespult werden. Auch hier ist es das Ziel, eine Kompaktheit der Teilfäden und unterscheidbare Farben im Garn zu erzielen.EP 0 784 109 A2 describes a method and a device for generating a described multi-colored yarns, in which differently colored or differently colored Partial threads are treated so that before a final joint Compacting the individual threads again, individually another so-called Subcompacted, merged, compacted and wound up. Again, the goal is a compactness of the threads and distinguishable To achieve colors in the yarn.

Die bekannten Verfahren weisen eine Reihe von Nachteilen auf. Eine Kompaktierung erfolgt meistens mittels Druckluft; diese Energieart ist sehr teuer, so daß die Herstellungskosten der Fäden mit der Anzahl der Kompaktiervorgänge stark ansteigen. Eine erste Kompaktierung ist unmittelbar hinter der Präparation angeordnet; dies bewirkt, daß durch die Kompaktierung ein Teil des Präparationsmittels aus dem Faden ausgetrieben wird und somit für den Herstellprozeß verloren ist. Weiterhin wird dieser Teil des Präparationsmittels infolge der Wirkung der Druckluft vernebelt; da hierdurch eine Gefährdung der Gesundheit des Bedienungspersonals und der Umwelt entsteht, muß jener Nebel aufgefangen und entsorgt werden. Schließlich bilden die durch die Kompaktierung erzeugten Knoten eine Inhomogenität und stören die Verstreckung.The known methods have a number of disadvantages. A compacting mostly done with compressed air; this type of energy is very expensive, so that the manufacturing costs of threads increase sharply with the number of compacting processes. A the first compacting is arranged directly behind the preparation; this causes, that part of the preparation is driven out of the thread by the compacting is and is therefore lost to the manufacturing process. This part continues nebulizing the preparation due to the action of compressed air; because of this one There is a risk to the health of the operating personnel and the environment that mist is caught and disposed of. Finally, they form through the compacting created nodes an inhomogeneity and disrupt the stretching.

Die Erfindung ist für die Herstellung verschiedener mehrfarbiger Garnqualitäten wie z.B. BCF (Bulced Continuous Filament; Teppichfaser) geeignet. Der Prozeß umfaßt die Schritte Spinnen und Kühlen der Filamente, Präparieren und Abziehen der zu Teilfäden zusammengefaßten Filamente, Verstrecken, Texturieren, Kompaktieren und Aufspulen. Filament beschreibt in den Ausführungen eine einzelne Faser, während Faden oder Garn eine zusammengefaßte Vielzahl von Filamenten ist. Ein Faden bzw. ein Garn ist aus mehreren Teilfäden zusammengesetzt, die vor einem Zusammenschluß getrennt bearbeitet werden.The invention is for the production of various multicolored yarn qualities such as e.g. BCF (Bulced Continuous Filament; carpet fiber) suitable. The process includes the Steps spinning and cooling the filaments, preparing and stripping the filaments summarized filaments, drawing, texturing, compacting and winding. Filament describes in the designs a single fiber, while thread or yarn is an aggregated variety of filaments. A thread or a Yarn is composed of several threads, which are before a merger processed separately.

Aufgabe der Erfindung ist es, ein Verfahren zur Herstellung schmelzersponnener Endlosfäden aufzuzeigen, bei dem mit minimalem Einsatz von Hilfsmitteln, wie z.B. Druckluft und Präparationsmittel, ein optimaler Fadenlauf auf den Galetten bei einer gleichzeitig hohen Belegung, besseres Verhalten bei weiteren Behandlungsschritten, wie Verstrecken und Texturieren, und bei mehrfarbigen Fäden ein großer Farbkontrast erzielt wird. Eine weitere Aufgabe besteht darin, eine Vorrichtung zur Durchführung des erfindungsgemäßen Verfahrens zu schaffen.The object of the invention is a method for producing melt-spun continuous filaments with the minimal use of aids, such as compressed air and preparation agent, an optimal thread run on the godets at the same time high occupancy, better behavior in further treatment steps, such as Stretching and texturing, and a great color contrast for multi-colored threads is achieved. Another object is to provide a device for performing the to create method according to the invention.

Die erste Aufgabe ist erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. Das Präparationsmittel, das an einer ersten Stelle aufgetragen wird, hat auf diese Weise genügend Zeit, weit in den Faden einzudringen und sich hier zu verteilen; dieser Prozeß wird besonders bei der Umlenkung am Abzugsorgan verstärkt, wo der Faden einer Walkarbeit unterworfen ist. Die zweite Präparation bewirkt, daß das Präparationsmittel insgesamt weitestgehend gleichmäßig auf die gesamte Oberfläche aller Filamente und ohne wesentlichen Überschuß aufgetragen werden kann. Dies begünstigt den Wärmeübergang zwischen Faden und Galetten und die weitere Bearbeitung, wie z.B. eine Verstreckung. Ein Faden behält eine kompakte Form ohne aufzuspleißen. Hierdurch ist es möglich, viele Fäden über eine Galette zu ziehen, und/oder eine große Umschlingungszahl zu fahren, ohne daß hierfür eine Kompaktierung erforderlich ist. Gleichzeitig sind sehr hohe Fadengeschwindigkeiten möglich. Die Gefahr eines Filamentbruches ist reduziert.The first object is according to the invention by the characterizing features of the claim 1 solved. The preparation agent that is applied in a first place in this way has enough time to penetrate far into the thread and to close here to distribute; this process is particularly intensified when the deflection element is deflected, where the thread is subjected to flexing. The second preparation causes the preparation as a whole largely evenly over the entire surface of all filaments and can be applied without a significant excess. This favors the heat transfer between thread and godet and further processing, such as. a stretch. A thread keeps a compact shape without splitting. This makes it possible to pull many threads over a godet, and / or to drive a large number of loops without a compacting for this is required. At the same time, very high thread speeds are possible. The The risk of filament breakage is reduced.

Die Begrenzung der Präparationsmittelmenge nach Anspruch 3 verhindert Verluste und Umweltbeeinträchtigungen durch Abspritzen des Mittels vom Faden.The limitation of the amount of preparation agent according to claim 3 prevents losses and environmental damage from spraying the agent off the thread.

Nach Anspruch 4 können die für die nachfolgenden Verfahrensschritte optimal wirkenden Präparationsmittel eingesetzt werden.According to claim 4, those acting optimally for the subsequent process steps can Preparations are used.

Anspruch 5 löst die zweite Aufgabe.Claim 5 solves the second problem.

Die Zeichnung dient der Erläuterung der Erfindung anhand eines vereinfacht und schematisch dargestellten Ausführungsbeispiels.The drawing serves to explain the invention using a simplified and schematic illustrated embodiment.

Die Figur zeigt eine Vorrichtung zur Herstellung eines mehrfarbigen schmelzersponnenen Endlosgarns am Beispiel für drei Farben.The figure shows an apparatus for producing a multi-colored melt-spun Continuous yarn using the example of three colors.

Bei der in der Figur dargestellten Vorrichtung ist jeweils unmittelbar unter drei Düsenplatten 1.1, 1.2, 1.3 ein Spinnschacht 2.1, 2.2, 2.3 angeordnet, in dem die unterschiedlich gefärbten oder anfärbenden Filamente 3.1, 3.2, 3.3, welche die Düsenplatten 1.1, 1.2, 1.3 verlassen, gekühlt werden. Eine Vielzahl Filamente 3.1, 3.2, 3.3 wird vor der weiteren Behandlung jeweils zu einem einzelnen Faden 4.1, 4.2, 4.3 zusammengefaßt. Hinter jedem Spinnschacht 2.1, 2.2, 2.3 ist eine erste Präparationsvorrichtung 5.1, 5.2, 5.3 angeordnet, die aus mehreren Präpariereinheiten, die unmittelbar hintereinander angeordnet sind, aufgebaut sein kann. Die präparierten Fäden 4.1, 4.2, 4.3 umschlingen mehrfach, z.B. 1,5 bis 2-fach eine antreibbare Galette 6 und eine Umlenkrolle 7. Galette 6 und Umlenkrolle 7 bilden das erste Abzugsorgan. Zwischen der Galette 6 und einem ersten Galettenpaar 8 ist jeweils eine zweite Präparationsvorrichtung 9.1, 9.2, 9.3 angeordnet. Das Galettenpaar 8 besteht aus zwei vertikal beabstandeten, jeweils antreibbaren und beheizbaren Galetten 8.1, 8.2 und ist mehrfach, z.B. 5 bis 13-fach von den Fäden 4.1, 4.2, 4.3 umschlungen. Dahinter befindet sich ein zweites Galettenpaar 10, das ebenfalls mehrfach von den Fäden 4.1, 4.2, 4.3 umschlungen ist. Die zugehörigen Galetten 10.1, 10.2 sind jeweils antreibbar und sowohl horizontal als auch vertikal beabstandet. Hinter der Galette 10.1 sind die Fäden 4.1, 4.2, 4.3 zusammengefaßt. Es ist weiter eine Texturiereinrichtung 11 angeordnet, gefolgt von einer antreibbaren Kühlwalze 12. Nach der Kühlwalze 12 gelangt der Faden 4 über eine antreibbare Galette 13 und eine Umlenkrolle 14 zur Kompaktiervorrichtung 15. Der Faden 4 ist dann über eine antreibbare Galette 16 und eine Umlenkrolle 17 zu einer Aufspulvorrichtung 18 geführt. Die gesamte Vorrichtung ab der ersten Präparationsvorrichtung 5, aber ohne die Aufspulvorrichtung 18, ist zweckmäßig auf einem Gestell 19 montiert.In the device shown in the figure is directly under three nozzle plates 1.1, 1.2, 1.3 a spinning shaft 2.1, 2.2, 2.3 arranged in which the different dyed or staining filaments 3.1, 3.2, 3.3, which the nozzle plates 1.1, 1.2, 1.3 leave, be cooled. A large number of filaments 3.1, 3.2, 3.3 is in front of the further treatment in each case combined into a single thread 4.1, 4.2, 4.3. Behind each spinning shaft 2.1, 2.2, 2.3 there is a first preparation device 5.1, 5.2, 5.3 arranged, which consist of several preparation units, the one behind the other are arranged, can be constructed. Loop the prepared threads 4.1, 4.2, 4.3 several times, e.g. 1.5 to 2 times a drivable godet 6 and a deflection roller 7. Galette 6 and deflection roller 7 form the first trigger element. Between the godet 6 and a first pair of godets 8 is a second preparation device 9.1, 9.2, 9.3 arranged. The pair of godets 8 consists of two vertically spaced, each drivable and heatable godets 8.1, 8.2 and is multiple, e.g. 5 to 13 times wrapped in threads 4.1, 4.2, 4.3. Behind it is a second one Pair of godets 10, which is also wrapped several times by the threads 4.1, 4.2, 4.3. The associated godets 10.1, 10.2 can each be driven and both horizontally and also vertically spaced. The threads 4.1, 4.2, 4.3 are combined behind the godet 10.1. A texturing device 11 is also arranged, followed by one drivable cooling roller 12. After the cooling roller 12, the thread 4 passes over a drivable Galette 13 and a deflection roller 14 to the compacting device 15. The thread 4 is then via a drivable godet 16 and a deflection roller 17 to a winding device 18 led. The entire device from the first preparation device 5, but without the winding device 18, is expediently mounted on a frame 19.

Im Betrieb wird geschmolzener, unterschiedlich gefärbter oder anfärbender Kunststoff durch die Düsenplatten 1.1, 1.2, 1.3 gepreßt und zu Filamenten 3.1, 3.2, 3.3 ersponnen. Diese werden im Spinnschacht 2 durch z.B. einen Luftstrom abgekühlt, so daß der Kunststoff der Filamente 3.1, 3.2, 3.3 erstarrt. Die zu einzelnen Fäden 4.1, 4.2, 4.3 zusammengefaßten Filamente 3 sind bis vor der Texturierung 11 getrennt gehalten, so daß jeweils eine separate Behandlung erfolgt. Dies ist zum einen durch eine entsprechende Fadenführung und zum anderen durch die Kompaktheit eines Fadens 4.1, 4.2, 4.3 infolge der Präparierung gewährleistet. Die Fäden 4.1, 4.2, 4.3 werden in der ersten Präparationsvorrichtung 5.1, 5.2, 5.3 mit Präparationsmittel benetzt; die Menge beträgt z.B. ca. 75 % der insgesamt erforderlichen Menge. Das Präparationsmittel bewirkt, daß die Fäden 4.1, 4.2, 4.3 während der weiteren Verarbeitung weitestgehend kompakt sind und daß ein guter Wärmeübergang zwischen Fäden und z.B. Galette erzielt wird. Die Fäden 4.1, 4.2, 4.3 werden über die Galette 6 und die Umlenkung 7 abgezogen und der zweiten Präparationsvorrichtung 9 zugeführt. Da das Präparationsmittel, das bei der ersten Präparationsvorrichtung 5.1, 5.2, 5.3 aufgetragen wurde, weitgehend in die Fäden 4.1, 4.2, 4.3 eindringen konnte, ist es jetzt möglich, die fehlende Menge an Präparationsmittel für die optimale Weiterverarbeitung aufzutragen. ohne daß ein nennenswerter Überschuß erforderlich ist. Es ist auch möglich, ein zweites Präparationsmittel zu benutzen. Die Fäden 4.1, 4.2, 4.3 werden dann in bekannter Weise mittels der Galettenpaare 8, 10 verstreckt und dann zusammengefaßt in der Texturiervorrichtung 11 gekräuselt, auf der Kühlwalze 12 gekühlt, in der Kompaktiervorrichtung 15 getangelt und schließlich mittels der Aufspulmaschine 18 auf Spulen gewickelt. Die Galetten 13, 16 mit den Umlenkrollen 14, 17 dienen jeweils dem Abzug des Fadens 4.Melted, differently colored or staining plastic is used in operation pressed through the nozzle plates 1.1, 1.2, 1.3 and spun into filaments 3.1, 3.2, 3.3. These are in the spinning shaft 2 by e.g. cooled an air stream so that the plastic of the filaments 3.1, 3.2, 3.3 solidifies. The individual threads 4.1, 4.2, 4.3 summarized filaments 3 are kept separate until texturing 11, so that there is a separate treatment. On the one hand, this is due to a corresponding Thread guidance and on the other hand through the compactness of a thread 4.1, 4.2, 4.3 guaranteed as a result of the preparation. The threads 4.1, 4.2, 4.3 are in the first preparation device 5.1, 5.2, 5.3 wetted with preparation agent; the amount is e.g. approx. 75% of the total amount required. The preparation agent causes that the threads 4.1, 4.2, 4.3 largely during the further processing are compact and that good heat transfer between threads and e.g. Galette is achieved. The threads 4.1, 4.2, 4.3 are on the godet 6 and the deflection 7 withdrawn and fed to the second preparation device 9. Because the preparation, that was applied to the first preparation device 5.1, 5.2, 5.3, could largely penetrate the threads 4.1, 4.2, 4.3, it is now possible to remove the missing Apply the amount of preparation for optimal processing. without a significant excess being required. It is also possible to have a second one To use preparative. The threads 4.1, 4.2, 4.3 are then known Stretched by means of the pairs of godets 8, 10 and then combined in the Texturing device 11 crimped, cooled on the cooling roll 12, in the compacting device 15 tangled and finally by means of the winding machine 18 on spools wound. The godets 13, 16 with the deflection rollers 14, 17 each serve the trigger of thread 4.

Die in der Figur beispielhaft dargestellte Vorrichtung kann auch so ausgeführt sein, daß mehrere, z.B. 2, 4, 6 oder 8 Fäden 4 gleichzeitig und parallel verarbeitet werden.The device shown as an example in the figure can also be designed such that several, e.g. 2, 4, 6 or 8 threads 4 can be processed simultaneously and in parallel.
