Definitions
- the invention relates to a method for air texturing of threads made of glass fibers, in which the threads are fed to a first delivery unit, from there to a texturing nozzle and then to a second delivery unit. It also relates to a device for carrying out such a method with a first and a second delivery mechanism and a texturing nozzle arranged between the two.
- a disadvantage of this method is that twisting as a separate work process before being fed to the texturing nozzle represents a considerable cost.
- Another disadvantage is that the twisting of brittle material requires the use of aids. So it is known, for example, to apply so-called textile sizing to glass fiber material in order to enable this material to be twisted at all.
- a disadvantage of this procedure is not only the additional cost, but also the fact that the textile size used is disadvantageous when the yarn is used later, for example by making it more difficult to embed it in a matrix.
- the blowing units causing a twist are therefore in front of the actual texturing zone and are intended to confuse the filaments of the threads and to break any connections between the filaments.
- the threads are loosened before entering the actual texturing device. Accordingly, there is a fear that when the threads subsequently run into a texturing nozzle, the flow into this nozzle will be disturbed by the filaments of the threads puffing up, clogging the nozzle and causing operational interruptions.
- the object of the present invention is now to provide a method of the type mentioned at the outset, with which the threads to be textured can be reliably fed to the texturing nozzle and textured uniformly there with considerably less effort.
- the threads should only be subjected to a slight load, so that the use of auxiliaries is also required for critical starting materials can at least largely be dispensed with.
- the object is achieved according to the invention in a method of the type mentioned at the outset in that the threads are fed separately or in a fan to the first delivery mechanism and in that the threads are given a false twist at least for the area between the inlet of the texturing nozzle and its outlet, which is the whole the threads fed into a unit.
- the method according to the invention can also be carried out in such a way that the threads between the texturing nozzle and the second delivery mechanism are guided via a false twister which gives the threads rotation in the region between the first delivery mechanism and the false twister.
- the method according to the invention can also be carried out in such a way that the yarn in the area of the texturing nozzle is given a rotation of up to 150 T / m.
- the method according to the invention can also be carried out in such a way that the yarn in the area of the texturing nozzle has a Z- or an S-turn is given. This enables a special effect to be achieved on the textured yarn.
- the method according to the invention can also be carried out in such a way that twisted and / or untwisted threads are fed to the first delivery mechanism.
- the textured yarns to be produced can have very special properties, in particular with regard to strength, elongation and volume.
- a device provided for carrying out the method according to the invention is characterized according to the invention in that a false twister is arranged between the texturing nozzle and the second delivery mechanism, the deflection body of which is a twist pin rotatably mounted about its axis, the axis of which is inclined to the direction of transport of the threads and the diameter of which is larger than 4 mm.
- the rotatable bearing of the twist pin avoids friction and thus stress on the individual threads when passing through the false twister.
- the threads can be guided in such a way that contact between the turns is avoided when passing through the swirl pin.
- the inclination of the twist pin with respect to the direction of transport of the threads prevents contact between the turns of the yarn when passing through the twist pin and thus also protects the material.
- a diameter of more than 4 mm also enables the processing of relatively brittle materials.
- the device according to the invention can be designed such that the false twister can be adjusted in its distance from the texturing nozzle.
- three unthreaded threads 1, 2, 3 are fed as multifilaments to a first delivery mechanism 4 of a conventional type.
- the threads 1, 2, 3 reach the feed mechanism 4 via an inlet 5 into a texturing nozzle 6, from which they emerge at the outlet 7.
- the threads 1, 2, 3 are then guided via a false twister 9 to a second delivery unit 10 and are drawn off from there in the direction of the arrow 11.
- the texturing nozzle 6 is of a known type. In it the threads 1, 2, 3 are blown up by blowing in compressed air in a manner known per se.
- the false twister 9 is provided with a drive, not shown, which rotates the false twister 9 about an axis running in the transport direction. It has a ring 12, in which a swirl pin 13 is held, which is freely rotatable according to arrow 14 about an axis running diametrically to the ring 12. The axis of the twist pin 13 does not run transversely to the direction of transport of the threads, but inclined to it.
- the threads form a loop on the swirl pin 13, the beginning and end of which do not touch due to the inclination of the swirl pin 13.
- the swirl pin 13 rotates according to the speed of transport of the threads.
- the relative speed between the outer surface of the swirl pin 13 on the one hand and the threads on the other hand is zero.
- the false twist sensor 9 can be adjusted in its distance from the texturing nozzle 6 in order to be able to adapt the device to the particular circumstances with regard to material and yarn titer.
- the take-off speeds of the delivery mechanisms 4, 10 are coordinated with one another in a known manner in order to take account of the shortening that occurs as a result of the bulging of the material.
- the threads 1, 2, 3 are fed to the false twister 9 via the first delivery mechanism 4 and the texturing nozzle 6.
- the threads 1, 2, 3 receive a rotation which is preferably below 100 T / m.
- the threads 1, 2, 3 fed individually to the first delivery mechanism 4 are combined to form a closed unit and, as such, are drawn into the texturing nozzle 6 at the inlet 5.
- the number of twists per unit length given to the threads is determined depending on the properties of the threads selected. The condition of the material must also be taken into account and it must be ensured that the number of rotations does not overload any of the materials used.
- the textured yarn leaving the outlet 7 still has the given twists. Due to the known false-wire effect, it has no more rotation after passing the false twister 9, which results in a further bulging.
- Bulkable threads can be processed using the method according to the invention and the device provided for this purpose.
- the processing of relatively brittle threads e.g. those made of glass fibers, possible because the method and device ensure gentle handling of these threads.
Abstract
Description
Die Erfindung betrifft ein Verfahren zum Lufttexturieren von Fäden aus Glasfasern, bei dem die Fäden einem ersten Lieferwerk, von dort einer Texturierdüse und anschließend einem zweiten Lieferwerk zugeführt werden. Sie betrifft ferner eine Vorrichtung zur Durchführung eines solchen Verfahrens mit einem ersten und einem zweiten Lieferwerk und einer zwischen beiden angeordneten Texturierdüse.The invention relates to a method for air texturing of threads made of glass fibers, in which the threads are fed to a first delivery unit, from there to a texturing nozzle and then to a second delivery unit. It also relates to a device for carrying out such a method with a first and a second delivery mechanism and a texturing nozzle arranged between the two.
Es ist bereits aus der US-A-33 81 346 bekannt, Fäden, z.B. auch solche aus Glasfasern, nicht verdreht über ein erstes Lieferwerk einer Texturierdüse zuzuführen und von dort einem zweiten Lieferwerk zuzuleiten. Bei diesem Vorgehen sind Brüche einzelner Filamente der zugeführten Fäden am Einlauf in die Texturierdüse zu befürchten, die zu Aufschiebungen und letztlich zum Fadenbruch führen können. Derartige einzeln geführte, unverdrehte Fäden führen in der Texturierdüse zu einem unkontrollierten und ungleichmäßigen Aufbauschen. Das so erhaltene texturierte Garn ist dann für viele Anwendungen nicht zufriedenstellend.It is already known from US-A-33 81 346 to thread, e.g. also those made of glass fibers, not twisted, to be fed via a first delivery unit to a texturing nozzle and from there to a second delivery unit. With this procedure, breakages of individual filaments of the supplied threads at the inlet into the texturing nozzle are to be feared, which can lead to postponements and ultimately to thread breaks. Such individually guided, untwisted threads lead to an uncontrolled and uneven bulging in the texturing nozzle. The textured yarn thus obtained is then unsatisfactory for many applications.
Es ist weiter bereits bekannt, Fäden ausgehend von Spinnspulen zusammenzufassen und mit einer Drehung zu versehen. Das so erzeugte Material kann dann einer Texturierdüse zugeführt werden. Aufgrund der Verzwirnung erfolgt eine Einbindung von etwa vorstehenden gebrochenen Filamenten. Diese Einbindung verhindert ein Aufschieben von gebrochenen Filamenten am Einlauf der Texturierdüse. Weiter ergibt dieses Material ein gleichmäßig gebauschtes texturiertes Garn.It is also already known to combine threads starting from spinning bobbins and to provide them with a twist. The material produced in this way can then be fed to a texturing nozzle. Due to the twisting, any broken filaments protruding above are integrated. This integration prevents broken filaments from being pushed onto the inlet of the texturing nozzle. This material also results in an evenly bulked textured yarn.
Nachteilig ist bei diesem Verfahren allerdings, daß das Verzwirnen als separater Arbeitsprozeß vor der Zuführung zur Texturierdüse einen erheblichen Kostenaufwand darstellt. Nachteilig ist weiter, daß das Verzwirnen bei spröderem Material die Anwendung von Hilfsmitteln erfordert. So ist es z.B. bekannt, bei Glasfasermaterial sogenannte Textilschlichte aufzubringen, um das Verzwirnen dieses Materials überhaupt zu ermöglichen. Nachteilig ist bei diesem Vorgehen nicht nur der zusätzliche Kostenaufwand, sondern auch die Tatsache, daß die angewandte Textilschlichte bei der späteren Verwendung des Garns von Nachteil ist, indem sie z.B. das Einbetten in eine Matrix erschwert.A disadvantage of this method, however, is that twisting as a separate work process before being fed to the texturing nozzle represents a considerable cost. Another disadvantage is that the twisting of brittle material requires the use of aids. So it is known, for example, to apply so-called textile sizing to glass fiber material in order to enable this material to be twisted at all. A disadvantage of this procedure is not only the additional cost, but also the fact that the textile size used is disadvantageous when the yarn is used later, for example by making it more difficult to embed it in a matrix.
Schließlich ist es aus der US-A 4 003 111 bekannt, Fäden jeweils von einer Spule abzuziehen und jeden für sich über eine Antriebswalze und eine Umlenkrolle einer Blaseinheit zuzuführen. Diese Blaseinheiten sollen in den Fäden einen Falschdrall bewirken, der ihren Zustand für ein nachfolgendes Lufttexturieren geeigneter macht. Nach dem bekannten Verfahren gelangen also die einzelnen Fäden jeder für sich nach dem Austreten aus den Blaseinheiten in die eigentliche Texturierzone und damit in den Wirkungsbereich von Texturierstrahlen. Die Fäden werden dann weiter einzeln über Rollen auf einen Haspel zu separaten Paketen aufgewickelt.Finally, it is known from US Pat. No. 4,003,111 to pull threads from a bobbin and to feed each of them individually to a blowing unit via a drive roller and a deflection roller. These blowing units are intended to cause a false twist in the threads, which makes their condition more suitable for subsequent air texturing. According to the known method, the individual threads each reach the actual texturing zone after exiting the blowing units and thus reach the area of effect of texturing jets. The threads are then wound up individually onto rolls on a reel to separate packages.
Bei der bekannten Vorrichtung befinden sich die einen Drall bewirkenden Blaseinheiten also vor der eigentlichen Texturierzone und sollen die Filamente der Fäden verwirren und etwaige Verbindungen zwischen den Filamenten aufbrechen. Die Fäden werden also vor dem Eintritt in die eigentliche Texturiereinrichtung aufgelockert. Demnach ist zu befürchten, daß beim nachfolgenden Einlaufen der Fäden in eine Texturierdüse der Einlauf in diese Düse gestört wird, indem die Filamente der Fäden sich aufbauschen, die Düse verstopfen und Betriebsunterbrechungen verursachen.In the known device, the blowing units causing a twist are therefore in front of the actual texturing zone and are intended to confuse the filaments of the threads and to break any connections between the filaments. The threads are loosened before entering the actual texturing device. Accordingly, there is a fear that when the threads subsequently run into a texturing nozzle, the flow into this nozzle will be disturbed by the filaments of the threads puffing up, clogging the nozzle and causing operational interruptions.
Die Aufgabe der vorliegenden Erfindung besteht nun darin, ein Verfahren der eingangs erwähnten Art anzugeben, mit dem bei erheblich reduziertem Aufwand die zu texturierenden Fäden zuverlässig der Texturierdüse zugeführt und dort gleichmäßig texturiert werden können. Dabei soll nur eine geringe Belastung der Fäden erfolgen, so daß auch bei kritischen Ausgangsmaterialien auf die Verwendung von Hilfsmitteln zumindest weitgehend verzichtet werden kann. Ferner ist es Aufgabe der Erfindung, eine zur Durchführung dieses Verfahrens geeignete Vorrichtung anzugeben.The object of the present invention is now to provide a method of the type mentioned at the outset, with which the threads to be textured can be reliably fed to the texturing nozzle and textured uniformly there with considerably less effort. In this case, the threads should only be subjected to a slight load, so that the use of auxiliaries is also required for critical starting materials can at least largely be dispensed with. It is also an object of the invention to provide a device which is suitable for carrying out this method.
Die gestellte Aufgabe wird bei einem Verfahren der eingangs erwähnten Art erfindungsgemäß dadurch gelöst, daß die Fäden separat oder gefacht dem ersten Lieferwerk zugeführt werden und daß den Fäden zumindest für den Bereich zwischen dem Einlauf der Texturierdüse und deren Auslauf ein Falschdrall aufgegeben wird, der die Gesamtheit der zugeführten Fäden zu einer Einheit zusammenfaßt.The object is achieved according to the invention in a method of the type mentioned at the outset in that the threads are fed separately or in a fan to the first delivery mechanism and in that the threads are given a false twist at least for the area between the inlet of the texturing nozzle and its outlet, which is the whole the threads fed into a unit.
Eine vorbereitende Bearbeitung, z.B. ein Verzwirnen, ist vor der Zuführung zum ersten Lieferwerk nicht erforderlich. Durch das Aufgeben eines Falschdralls und das daraus resultierende Zusammenschließen der Fäden zu einer Einheit werden etwa vorliegende Fadenbrüche eingebunden, so daß es am Düseneinlauf nicht zu Stauungen und Versetzungen kommen kann. Der somit in die Texturierdüse einlaufende Zusammen schluß von Fäden führt zu einer gleichmäßigen Aufbauschung des Garns.Preparatory processing, such as twisting, is not necessary before being fed to the first supplier. By giving up a false twist and the resulting joining of the threads to form a unit, any thread breaks present are incorporated, so that there can be no jams and dislocations at the nozzle inlet. The combination thus entering the texturing nozzle closure of threads leads to an even bulging of the yarn.
Das erfindungsgemäße Verfahren kann ferner so ausgeführt werden, daß die Fäden zwischen der Texturierdüse und dem zweiten Lieferwerk über einen Falschdrallgeber geführt werden, der den Fäden im Bereich zwischen dem ersten Lieferwerk und dem Falschdrallgeber eine Drehung gibt.The method according to the invention can also be carried out in such a way that the threads between the texturing nozzle and the second delivery mechanism are guided via a false twister which gives the threads rotation in the region between the first delivery mechanism and the false twister.
Indem die Fäden nach Passieren der Texturierdüse über einen Falschdrallgeber geführt werden, wird ihnen im Bereich zwischen dem ersten Lieferwerk und dem Falschdrallgeber eine Drehung gegeben, welche die Gesamtheit der zugeführten Fäden zu einer Einheit zusammenbindet, welche etwa vorhandene Brüche von einzelnen Filamenten einschließt. Ein ordnungsgemäßer Einlauf des so gedrehten Garns ist damit sichergestellt. Die auf diese Weise gebildete Einheit wird auch in der Texturierdüse als Gesamtheit der eingeblasenen Luft ausgesetzt. Dies führt dazu, daß nicht einzelne Fäden für sich angegriffen werden, sondern die gesamte Einheit. Das Ergebnis ist eine gleichmäßige Aufbauschung dieses Garns. Dieser Vorteil wird also nicht durch gesonderte Zwirn- und Umspulvorgänge erreicht, sondern lediglich durch Einschaltung eines Falschdrallgebers beliebiger bekannter Bauart in den Garnfluß.By passing the threads over a false twister after passing through the texturing nozzle, they are given a rotation in the area between the first delivery unit and the false twister, which combines the entirety of the threads fed into one unit, which includes any breaks in individual filaments. This ensures that the twisted yarn is properly fed in. The unit formed in this way is also exposed in the texturing nozzle as a whole to the blown-in air. This means that not individual threads are attacked, but the entire unit. The result is an even bulging of this yarn. This advantage is therefore not achieved by separate twisting and rewinding processes, but only by switching on a false twister of any known type in the yarn flow.
Das erfindungsgemäße Verfahren kann ferner so ausgeführt werden, daß dem Garn im Bereich der Texturierdüse eine Drehung bis zu 150 T/m aufgegeben wird. In vielen Fällen ist es vorteilhaft, den Fäden im Bereich der Texturierdüse eine Drehung von weniger als 100 T/m aufzugeben. Diese Drehung sichert die angestrebten vorteilhaften Effekte bei der Einleitung der Fäden in die Texturierdüse sowie beim Blasvorgang in der Düse selbst. Dabei wird aber durch eine reduzierte Drehung der Fäden die Belastung der einzelnen Filamente und damit die Gefahr von Brüchen reduziert.The method according to the invention can also be carried out in such a way that the yarn in the area of the texturing nozzle is given a rotation of up to 150 T / m. In many cases it is advantageous to give the threads a rotation of less than 100 T / m in the area of the texturing nozzle. This rotation ensures the desired advantageous effects when the threads are introduced into the texturing nozzle and during the blowing process in the nozzle itself. In this case, however, a reduced rotation of the threads reduces the load on the individual filaments and thus the risk of breakage.
Das erfindungsgemäße Verfahren kann ferner so ausgeführt werden, daß dem Garn im Bereich der Texturierdüse eine Z- oder eine S-Drehung gegeben wird. Dadurch kann ein besonderer Effekt am texturierten Garn erzielt werden.The method according to the invention can also be carried out in such a way that the yarn in the area of the texturing nozzle has a Z- or an S-turn is given. This enables a special effect to be achieved on the textured yarn.
Das erfindungsgemäße Verfahren kann ferner so ausgeführt werden, daß dem ersten Lieferwerk gedrehte und/oder ungedrehte Fäden zugeführt werden. Durch Abstimmung der Materialien und der Drehung der Fäden können die zu erzeugenden texturierten Garne ganz spezielle Eigenschaften insbesondere hinsichtlich Festigkeit, Dehnung und Volumen erhalten.The method according to the invention can also be carried out in such a way that twisted and / or untwisted threads are fed to the first delivery mechanism. By coordinating the materials and the rotation of the threads, the textured yarns to be produced can have very special properties, in particular with regard to strength, elongation and volume.
Eine zur Durchführung des erfindungsgemäßen Verfahrens vorgesehene Vorrichtung zeichnet sich erfindungsgemäß dadurch aus, daß zwischen der Texturierdüse und dem zweiten Lieferwerk ein Falschdrallgeber angeordnet ist, dessen Umlenkkörper ein um seine Achse drehbar gelagerter Drallstift ist, dessen Achse geneigt zur Transportrichtung der Fäden verläuft und dessen Durchmesser größer als 4 mm ist.A device provided for carrying out the method according to the invention is characterized according to the invention in that a false twister is arranged between the texturing nozzle and the second delivery mechanism, the deflection body of which is a twist pin rotatably mounted about its axis, the axis of which is inclined to the direction of transport of the threads and the diameter of which is larger than 4 mm.
Die drehbare Lagerung des Drallstifts vermeidet Reibung und damit Belastung der einzelnen Fäden beim Passieren des Falschdrallgebers. Die Führung der Fäden kann dabei so erfolgen, daß beim Passieren des Drallstiftes Berührungen zwischen den Windungen vermieden werden. Die Neigung des Drallstiftes bezüglich der Transportrichtung der Fäden verhindert Berührungen zwischen den Windungen des Garns beim Passieren des Drallstifts und schont somit ebenfalls das Material. Ein Durchmesser von mehr als 4 mm ermöglicht auch die Verarbeitung von relativ spröden Materialien.The rotatable bearing of the twist pin avoids friction and thus stress on the individual threads when passing through the false twister. The threads can be guided in such a way that contact between the turns is avoided when passing through the swirl pin. The inclination of the twist pin with respect to the direction of transport of the threads prevents contact between the turns of the yarn when passing through the twist pin and thus also protects the material. A diameter of more than 4 mm also enables the processing of relatively brittle materials.
Schließlich kann die erfindungsgemäße Vorrichtung so ausgebildet sein, daß der Falschdrallgeber in seinem Abstand von der Texturierdüse einstellbar ist.Finally, the device according to the invention can be designed such that the false twister can be adjusted in its distance from the texturing nozzle.
Es ist für jeden Fachmann selbstverständlich, daß die Einstellung und Auswahl der einzelnen Maße, so z.B. des Durchmessers des Drallstifts, der Position des Falschdrallgebers zur Texturierdüse und die in den Lieferwerken erfolgenden Umlenkungen den jeweiligen Erfordernissen des betroffenen Materials sowie dem Garntiter anzupassen sind.It is self-evident for every specialist that the setting and selection of the individual dimensions, for example the diameter of the swirl pin, the position of the false twister to the texturing nozzle and the deflections taking place in the supplying plants must be adapted to the respective requirements of the material concerned and the yarn titer.
