Es sind Verfahren und Vorrichtungen zum Texturieren von mindestens teilweise aus thermoplastischem Material bestehenden Textilgarnen bekannt, mit welchen dem Garn ein hoher Falschdrall erteilt wird. Dabei wird das Garn im hochgedrehten Zustand durch Erhitzen vorübergehend in einen plastisehen Zustand übergeführt, worauf durch Abkühlen die Wiedererhärtung und damit die Fixierung der spiraligen Deformation der Faserfibrillen erfolgt. Bei den bekannten Falschdrallvorrichtungen zum Texturieren erfolgt die Erhitzung der Garne z. B. mittels eines von diesen durchlaufenen Heißluftkanals oder durch Kontakt mit einer heißen Fläche, und die Abkühlung erfolgt in der Regel beim Durchlaufen einer Raumtemperatur aufweisenden Luftstrecke.There are methods and devices for texturing at least partially thermoplastic Material existing textile yarns known, with which the yarn is given a high false twist will. The yarn is temporarily turned into a plastic when it is turned up State transferred, whereupon the re-hardening and thus the fixation of the spiral by cooling Deformation of the fiber fibrils takes place. In the known false twist devices for texturing the heating of the yarns z. B. by means of one of these traversed hot air duct or by contact with a hot surface, and cooling usually occurs when passing through a Air gap at room temperature.
Es hat sich jedoch gezeigt, daß bei höheren Garndurchlaufgeschwindigkeiten diese Luftstrecke relativ lang sein müßte, um eine genügende Abkühlung zu erreichen, weshalb man in solchen Fällen genötigt ist, durch intensivere Kühlung mittels einer besonderen, sich an die Erhitzungsvorrichtung anschließenden Kühlvorrichtung die Abkühlstrecke so kurz wie möglich zu machen.However, it has been shown that at higher yarn speeds this air gap would have to be relatively long in order to achieve sufficient cooling, which is why it is necessary in such cases, through more intensive cooling by means of a special one connected to the heating device Cooling device to make the cooling distance as short as possible.
Es sind deshalb auch Falschdrallvorrichtungen zum Texturieren von Garnen bekanntgeworden, bei welchen als Kühlvorrichtung z. B. ein vom Garn durchlaufenes Rohr dient, das von gekühlter Luft oder Gas durchströmt ist. Diese Vorrichtungen haben jedoch den Nachteil, daß die damit erzielbare Kühlung noch nicht intensiv genug ist für sehr hohe Garndurchlaufsgeschwindigkeiten, wie sie mit den modernen, hochtourigen Falschdrallvorrichtungen möglich geworden sind.False twist devices for texturing yarns have therefore also become known at which as a cooling device z. B. a tube traversed by the yarn is used, which is cooled by air or gas is flowing through it. However, these devices have the disadvantage that the cooling that can be achieved therewith is not yet intensive enough for very high yarn throughput speeds, as is the case with modern, high-speed false twist devices have become possible.
Es ist ferner eine Vorrichtung zum Verhindern des Austretens von Öldämpfen aus den Heizrohren von Falschdraht-Zwirnmaschinen bekannt, wobei bei jedem Heizrohr eine mit Unterdruck arbeitende Absaugstelle vorgesehen ist. Es wird dabei zusätzlich von oben her Raumluft im Gegenstrom an den Fäden vorbeigeführt, wodurch auch eine gewisse Kühlung der Fäden erzielt wird (deutsches Gebrauchsmuster 1 898 539).It is also a device for preventing the Leakage of oil vapors from the heating pipes of false twisting machines is known, with each Heating pipe a suction point working with negative pressure is provided. It is doing this in addition From above, ambient air is led past the threads in countercurrent, which also provides a certain amount of cooling of the threads is achieved (German utility model 1 898 539).
Der Erfindung liegt die Aufgabe zugrunde, eine Kühlvorrichtung mit hohem Wirkungsgrad zu schaffen, wodurch sich die Länge der Kühlstrecke auf ein Minimum verkürzen und damit den Raumbedarf der Texturiervorrichtung verringern läßt. Die Aufgabe wird durch die im Anspruch 1 angegebene Erfindung gelöst. Ausgestaltungen der Erfindung sind in den Unteransprüchen beschrieben.The invention is based on the object of creating a cooling device with high efficiency, whereby the length of the cooling section is reduced to a minimum and thus the space requirements of the Can reduce texturing device. The object is achieved by the invention specified in claim 1 solved. Refinements of the invention are described in the subclaims.
Die erfindungsgemäße Vorrichtung eignet sich nicht nur für die üblichen, eine Falschdrallvorrichtung enthaltenden Texturiervorrichtungen, sondern auch für solche zur vorübergehenden, gegenseitigen Verzwirnung von mehreren Garnen ohne Drallgeber und einer Einrichtung zur Hitzebehandlung der Garne im verzwirnten Zustand, wie sie z.B. in der schweizerischen Patentschrift 392767 und 425 076 beschrieben sind.The device according to the invention is not only suitable for the usual, false twist device containing texturing devices, but also for those for temporary, mutual Twisting of several yarns without a twist generator and a device for heat treatment of the Twisted yarns, such as those in Swiss Patent 392767 and 425 076 are described.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben. Es zeigtAn embodiment of the invention is shown in the drawing and will be described in more detail below described. It shows
F i g. 1 eine schematische Darstellung der gesamten Texturiervorrichtung,F i g. 1 a schematic representation of the entire texturing device,
F i g. 2 eine Ausführungsform der Saugvorrichtung im Aufriß unF i g. Figure 2 shows an embodiment of the suction device in elevation
F i g. 3 die gleiche Ausführungsform der Saugvorrichtung im Querschnitt.F i g. 3 shows the same embodiment of the suction device in cross section.
Gemäß F i g. 1 gelangt das von der Lieferspule 1 kommende Textilgarn 2 über ein erstes Förderwalzenpaar 3 in die Erhitzungsvorrichtung 4, in welcher es z. B. mittels Heißluft oder durch Kontakt mit einer heißen Fläche in einen plastischen Zustand übergeführt wird. Danach wird das Garn 2 durch die Saugvorrichtung 5 geführt, wo es durch Kühlung wieder erhärtet.According to FIG. 1, the textile yarn 2 coming from the delivery spool 1 passes over a first pair of conveyor rollers 3 in the heating device 4, in which there is z. B. by means of hot air or by contact with a hot surface is converted into a plastic state. After that, the yarn 2 is passed through the suction device 5, where it hardens again by cooling.
Das Garn 2 passiert sodann nacheinander den Drallgeber 6 zur Erteilung des Falschdralls sowie ein zweites Förderwalzenpaar 7 und gelangt sodann zu einer nicht dargestellten Aufwickelvorrichtung. Die Saugvorrichtung 5 besteht, wie aus den F i g. 2 und 3 ersichtlich ist, aus einem verschlossenen Rohr 8 mit rechteckigem Querschnitt, dessen obere Wandfläche 9 eine Rinne 10 aufweist, in welcher in regelmäßigen Abständen von etwa 0,5 cm Löcher 11 mit einem Durchmesser von etwa 2,5 mm angebracht sind. An der unteren Wandfläche 12 ist ein Stutzen 13 angebracht, über welchen die Saugvorrichtung 5 mit einem nicht dargestellten Ventilator verbunden ist. Letzterer erzeugt eine Saugkraft von etwa 20 bis 100 mm Wassersäule, welche je nach der zwischen 100 und 500 m/min betragenden Garndurchlaufsgeschwindigkeit entsprechend eingestellt wird.The yarn 2 then successively passes the twist generator 6 for issuing the false twist and a second pair of conveyor rollers 7 and then arrives at a winding device, not shown. the Suction device 5 consists, as shown in FIGS. 2 and 3 can be seen, from a sealed tube 8 with rectangular cross-section, the upper wall surface 9 has a groove 10 in which in regular At intervals of about 0.5 cm holes 11 with a diameter of about 2.5 mm are. A nozzle 13 is attached to the lower wall surface 12, via which the suction device 5 is connected to a fan, not shown. The latter generates a suction force of around 20 to 100 mm water column, which depending on the yarn passage speed between 100 and 500 m / min is set accordingly.
Wenn das von der Erhitzungsvorrichtung 4 kommende Garn 2 die Rinne 10 durchläuft, hat die durch die Löcher 11 einströmende Luft folgende Wirkungen: When the yarn 2 coming from the heating device 4 passes through the channel 10, it has through Air flowing into the holes 11 has the following effects:
a) die heiße, das Garn umgebende Grenz-Luftschicht, welche es aus der Erhitungsvorrichtung 4 mitschleppt, wird abgetrennt,a) the hot boundary layer of air surrounding the yarn which it exits the heating device 4 dragged along, is separated,
b) das Garn wird mit der angesaugten, kalten Luft direkt in Berührung gebracht,b) the yarn is brought into direct contact with the cold air that is sucked in,
c) der Hohlkörper bzw. die Rinne 10 wird durch die angesaugte Luft selbst gekühlt,c) the hollow body or the channel 10 is cooled by the sucked in air itself,
d) das Garn wird in die Rinne 10 hineingezogen und ist in engem Kontakt mit derselben (Kontaktkühlung). d) the yarn is drawn into the channel 10 and is in close contact with the same (contact cooling).
Mit der erfindungsgemäßen Saugvorrichtung werden außerdem die Dämpfe von Schlichtemitteln und anderen Präparaten, mit welchen die Textilgarne vorgängig behandelt worden sind, abgesogen, wodurch eine Verschmutzung der Texturiermaschine und des Raumes, in welchem diese aufgestellt ist, unterbleibt. Eine nachteilige Erscheinung bei den der Falschdrallung unterworfenen Textilgarnen besteht bekanntlich darin, daß sie infolge ihrer raschen Rotation um ihre Achse zu einer mehr oder weniger starken Ballonbildung neigen, welche die Qualität des texturierten Garns ungünstig beeinflussen kann. Mit der erfindungsgemäßen Saugvorrichtung läßt sich diese Ballonbildung infolge Ansaugung des Garns in der Rinne weitgehend vermeiden.With the suction device according to the invention, the vapors of sizing agents and other preparations with which the textile yarns have previously been treated, sucked off, whereby the texturing machine and the room in which it is set up are not soiled. It is known that there is a disadvantageous phenomenon in the case of the textile yarns subject to false twist in the fact that, as a result of their rapid rotation around their axis, they lead to a more or less strong balloon formation tend, which can adversely affect the quality of the textured yarn. With the invention Suction device can this balloon formation as a result of suction of the yarn in the Avoid gutters as much as possible.
