Definitions
- the invention relates to a method for producing a crimped composite thread according to the preamble of claim 1 and to an apparatus for carrying out the method according to the preamble of claim 12.
- a plurality of synthetic monofilaments are first extruded, cooled, and drawn, respectively, as a plurality of rope-shaped filaments.
- the individual threads in this case have different properties, preferably different colors, so that the coloring of the composite thread is determined by mixing the individual threads. Depending on the application for the composite thread, this results in different requirements in the color image of the composite thread.
- There is a desire to produce a mixing of the individual threads which leads neither to a dominant emergence of the monofilament, nor to a complete mixing of the individual threads in the composite thread.
- the dominant emergence of a color component in the composite thread can - if this is too long - lead to so-called "flames" as elongated portions of the same color are named.
- flames are desirable in most cases.
- the multifilament monofilaments are guided by a common crimping to form a composite thread.
- the monofilaments are guided together with the aid of a delivery nozzle in a stuffer box.
- the filaments of the monofilaments lay to loops and bows and form a common thread plug.
- a crimping of the filaments and, on the other hand a mixing of the filaments of the monofilaments is produced.
- each of the monofilaments is vortexed separately before the common crimping, so that the entanglement of the filaments within the monofilament form a Clfaden gleich.
- the mixing of the monofilaments in the composite yarn could be improved in terms of color separation.
- there is a desire for color design in the composite thread such that both composite threads can be produced in a mixed color with strong mixing of the individual threads or with strong thread separation without intensive mixing of the individual threads.
- Another object of the invention is to provide a reproducible adjustability for the color image of the composite thread.
- the invention is based on the finding that the swirling of multifilament threads can be used with very different effects.
- the swirling of a multifilament yarn can be used to create a blending or knotting of the filaments of the yarn.
- the intensity of the thread conclusion which is essentially also directed to the respective treatment step on the thread, determined.
- the invention begins, which provides for multiple turbulences of at least one of the multifilament yarns.
- the treatment steps carried out, in particular, until the individual threads have been crimped can be carried out with individually adjusted turbulences to form a thread closure.
- at least one of the multifilament monofilaments is vortexed several times before crimping in several preliminary stages.
- a further advantage of the invention is given by the fact that the common texturing of the monofilaments can be maintained to the composite thread. Just the multiple turbulence of the individual threads allows a flexible design of the coloring in the composite thread. Thus, to set a high color separation, each of the individual threads can be swirled in several preliminary stages. In order to obtain mixing phenomena in the composite thread, preferably only one of the multifilament monofilaments is swirled into a plurality of precursors.
- the method variant in which each of the multifilament monofilaments is vortexed separately in a first precursor before being drawn, is characterized from that the individual threads in the drawing device with high smoothness and small distance from each other by the drawing device can be guided.
- the swirling of the individual threads introduced in the first preliminary stage can be exclusively geared to obtaining an optimum thread closure for the stretching of the individual threads.
- the method variant is preferably used, in which at least one of the individual threads or all individual threads are separately entangled in a second preliminary stage after stretching.
- the thread closure produced by the turbulence on the individual threads can be turned off solely on the subsequent common crimping of the individual threads.
- the adjustability and the bandwidth of the coloring of the composite thread can also be improved by swirling the individual threads in at least one of the preliminary stages, each with different compressed air control values of a compressed air supply.
- different Verwirbelungsgrade can be adjusted at the parallel guided individual threads.
- the color-determining single thread can be swirled with relatively high compressed air control values.
- the height of the compressed air control values is proportional to the braiding node produced in the thread.
- a pulsation of the pressure to turbulence can be carried out in order to vary the color mixture. This makes it possible to produce special yarn effects for the production of fancy yarns.
- the process variant has proven particularly useful in which the multifilament monofilaments are swirled by a heated compressed air. Alternatively, however, it is also possible to heat the monofilament before swirling. In this case, it was possible to determine influences on the generated entanglement of the filaments in the monofilaments as well as effects on crimping of the composite thread.
- the process variant is particularly advantageous in which the monofilaments before curling with multiple wrapping led to a godet unit and in a thread piece of wraps before expiration of the Galettenhim be swirled.
- the composite thread after the crimping of the individual threads and before winding wound into a coil, wherein the color produced by the vortex swirling in the precursors and by the crimping of the individual threads of the composite thread substantially preserved.
- the inventive method is particularly suitable for the production of a composite thread, which is formed from a plurality of preferably different partial threads.
- the invention is not limited to partial threads of different Texture, since in particular an individual pretreatment of the monofilaments can also be used advantageously in composite threads, which are formed of identical partial threads.
- structural features of the monofilaments are in the foreground, which can be generated by the different Vorverwirbelung carried out in two stages.
- the inventive method is also suitable, after a separate turbulence in a first stage to swirl all the individual threads together in the second precursor. Due to the multi-stage turbulence before texturing, the invention offers a very high degree of flexibility in the pretreatment of the monofilaments before texturing. Thus, it is also possible that the monofilaments in the first precursor are mixed together and in the second precursor are vortexed separately.
- inventive method is not limited to that the individual threads are crimped together.
- each of the individual threads is textured separately before merging the individual threads.
- a further variant of the method can also be carried out in such a way that, after a common or separate texturing and merging of the individual threads into the composite thread, the composite thread is separated again into partial threads after cooling, which are subsequently swirled together before being wound up into the final composite thread.
- Such a variant of the method can be used with differently dyed individual threads in order to obtain additional color settings.
- the device according to the invention has a swirling device formed from a plurality of swirling units, wherein the swirling units are arranged one behind the other in the yarn path of the monofilaments.
- a first swirling unit of the stretching unit is advantageously arranged upstream, wherein the first swirling unit has a swirling nozzle for each of the individual threads.
- a second turbulence unit with a plurality of fluidizing nozzles is advantageously arranged between the drawing device and the curling device.
- the swirling nozzles are each assigned a controllable compressed air supply.
- the compressed air supply both simultaneously supply a plurality of swirling nozzles or can be used for the separate supply of a swirling nozzle.
- the device according to the invention can be expanded in such a way that at least one of the turbulence units is assigned a heating means by which compressed air can be heated.
- the turbulence unit could be preceded by a heating device, by means of which the individual filaments can be heated.
- the device according to the invention is preferably used, in which the stretching device has a godet unit upstream of the curling device, on which the monofilaments are guided with multiple wrapping, and in which the swirling nozzles of the second turbulence unit of the godet unit are assigned such that the individual threads are vortexed before expiry of the godet unit.
- the second Verwirbelsaku in a Umschlingungsast between two Godets can be set in the arrangement of the Verwirbelungsdüsen in the last wrap a lowering of the thread tension in the swirl that the individual threads at expiration of the godet unit to a step jump of the godet with reduced Diameter to be guided.
- any Umschlingungsast between the godet duo is suitable for the arrangement of the Verwirbelungsdüse in order to carry out a swirling in the second stage.
- the godet unit can be formed according to an advantageous development of the device at least by two driven godets, wherein at least one of the godets is formed heatable.
- Tangel founded on the composite thread For the final production of a thread closure in the composite thread a Tangel founded on the composite thread.
- the device variant in which the crimping device has a stuffer box and a delivery nozzle assigned to the delivery nozzle has proved particularly useful.
- the individual threads are conveyed together by means of the delivery nozzle in the stuffer box and popped up to a yarn plug.
- a first embodiment of a device according to the invention for carrying out the method according to the invention is shown schematically.
- the device has a spinning device 1, which is connected to one or more melt generators (not shown here).
- the spinning device has a heated spinning beam 2, which carries a plurality of spinnerets 3.1 to 3.3 next to each other.
- the spinnerets 3.1 to 3.3 each have on their undersides a plurality of nozzle bores through which the spinnerets 3.1 to 3.3 each supplied polymer melt streams are extruded under pressure to a plurality of individual filaments.
- a cooling device 4 is provided, through which the extruded filaments are guided, so that the emerging at approximately melt temperature individual filaments are cooled.
- the cooling device 4 could be formed, for example, by an injection, through which a cooling air is blown substantially transversely onto the filaments. After the filaments have cooled, the respective filament strands 13.1, 13.2 and 13.3 assigned to one of the spinnerets 3.1, 3.2 and 3.3 are combined to form a single filament 6.1, 6.2 and 6.3 at the outlet of the cooling device 4.
- a preparation device 7 and the yarn guides 5.1, 5.2 and 5.3 associated with the individual threads 6.1, 6.2 and 6.3 are provided at the outlet of the cooling device 4.

- the crimping device 11 is formed in this Ausyogbrungsbeispiel by a delivery nozzle 15 and a cooperating with the delivery nozzle 15 stuffer box 16.
- the delivery nozzle 15 is connected to a pressure source (not shown) through which a delivery medium of the delivery nozzle 15 is supplied. Due to the pumped medium, the monofilaments 6.1, 6.2 and 6.3 are drawn into the delivery nozzle 15 and then popped up in the stuffer box 16 to form a thread stopper. In this case, partial mixing of the individual threads 6.1 to 6.3 occurs.
- the yarn plug 22, preferably produced by a hot conveying medium, is subsequently guided to a cooling drum 17 and cooled.
- a first swirling unit 8.1 and a second swirling unit 8.2 between the stretching device 10 and the cooling device 11 are arranged between the dissection device 7 and the stretching device 10.
- the first turbulator 8.1 has several Vortex nozzles 9.1, 9.2 and 9.3, which are each assigned to the individual threads 6.1, 6.2 and 6.3.
- Each of the swirl nozzles 9.1, 9.2 and 9.3 contains a thread channel through which the monofilament is guided.
- a pressure channel opens laterally in the thread channel in order to introduce a fluid, preferably with high energy, into the thread channel.
- the pressure channels are connected via a compressed air supply 12.1 and a pressure actuating means 14.1 with a pressure source. To set a compressed air control value, the pressure actuating means 14.1 is coupled to a control device 24.

- the second turbulence unit 8.2 upstream of the crimping device 11 likewise has a plurality of turbulence nozzles, which are identified by the reference numerals 9.4 to 9.6.
- the structure of the Verwirblungsdüsen 9.4 to 9.6 of the second Verwirbelungsaku 8.2 is substantially identical to the structure of the Verwirbelungsdüsen 9.1 to 9.3 of the first Verwirbelungsaku 8.1.
- the swirl nozzles 9.4 to 9.6 are connected via the compressed air supply 12.2 and the pressure actuating means 14.2 with a pressure source, not shown here.
- the pressure adjusting means 14.2 is coupled with the control device 24 for setting and changing a compressed air control value.
- the swirling units 8.1 and 8.2 can thus be operated independently of each other for swirling the individual threads 6.1 to 6.3.
- the crimping device 11 For post-treatment of the crimped composite thread 21 formed by the individual threads 6.1 to 6.3, the crimping device 11 is followed by a tangling device 19. Within the tangle device 19, the composite thread 21 receives a last thread-finishing treatment required for further processing.
- the composite yarn 21 is taken up by the take-up device 20 and wound into a coil 23.
- the take-up device 20 simultaneously serves as a take-off member to remove the crimped composite yarn 21 from the yarn plug 22.
- the composite yarn 21 can also be deducted by a Abzugsgalette from the yarn plug 22 and lead by another of the Tangel worn 19 downstream godet unit to the take-up device 20.
- the configuration of the devices in the aftertreatment zone does not affect the method according to the invention, so that any desired processing units and treatment stages can be executed on the composite thread 21 until it has been wound up into a coil 23.
- Fig. 1 illustrated embodiment of the device according to the invention are spun by the spinnerets 3.1, 3.2 and 3.3 three parallel side by side guided filament bundles 13.1, 13.2 and 13.3, each with a plurality of filament strands.
- the filament bundles 13.1, 13.2 and 13.3 in this case have different properties, preferably a different coloring of the base polymer.
- the filament bundles contain different base polymers or in each case different additive admixtures.

- the filament bundles 13.1, 13.2 and 13.3 are each supplied with a preparation medium by the preparation device 7 and connected by the thread guides 5.1, 5.2 and 5.3 to the respective monofilaments.
- a first turbulence is performed by the turbulence unit 8.1 in a first preliminary stage immediately after preparation.
- each of the individual threads 6.1 to 6.3 is guided through a swirl nozzle 9.1 to 9.3.
- the swirling unit 8.1 has a pressure set value of the supplied compressed air, which leads to an interlacing which leads to the filament forming filaments.
- a homogenization of the preparation application is achieved on the one hand, and on the other hand, a minimum thread closure required for the subsequent godet guide in the stretching device 10 is established.
- care must be taken that no excessive knotting of the filaments of the individual threads occurs.
- the individual threads 6.1 to 6.3 are each guided and swirled separately through the swirling nozzles 9.4 to 9.6.
- the entanglement of the filaments introduced in the individual threads 6.1 to 6.3 is selected so that a certain mixing occurs during the crimping of the individual threads 6.1 to 6.3 to form the composite thread 2.1
- the coloring of the composite thread 21 in FIG wide limits are influenced.
- a composite thread 21 with strong color separation can be produced in that during the swirling in the second swirling unit 8.2 a relatively high pressure control value of the supplied compressed air is inserted. This produces an intensive intertwining of the filaments of the monofilament, which can be little solved even during the subsequent crimping treatment. Conversely, by setting a low pressure set value in the swirling unit 8.2, it is possible for the composite thread 21 to have a more or less strong mixed color.
- the individual threads 6.1 to 6.3 are co-crimped together and combined to form the composite thread 21.
- the monofilaments 6.1 to 6.3 are conveyed through the delivery nozzle 15 with a delivery fluid into an adjacent stuffer box 16.
- the filaments of the individual threads 6.1 to 6.3 wrap themselves in loops and sheets to form a thread stopper 22, which is dissolved after thermal treatment to form the crimped composite thread 21.
- the composite thread 21 is dangled prior to winding to a coil 23 in the Tangel liked 19.

Abstract
Description
Die Erfindung betrifft ein Verfahren zur Herstellung eines gekräuselten Verbundfadens gemäß dem Oberbegriff des Anspruchs 1 sowie eine Vorrichtung zur Durchführung des Verfahrens gemäß dem Oberbegriff des Anspruchs 12.The invention relates to a method for producing a crimped composite thread according to the preamble of
Bei der Herstellung eines gekräuselten Verbundfadens in einem einstufigen Herstellungsprozess werden zunächst mehrere synthetische Einzelfäden jeweils als eine Vielzahl von strangförmigen Filamente extrudiert, abgekühlt und verstreckt. Die Einzelfäden weisen dabei unterschiedliche Eigenschaften bevorzugt unterschiedliche Farben auf, so dass die Farbgebung des Verbundfadens durch ein Vermischen der Einzelfäden bestimmt ist Je nach Anwendungsfall für den Verbundfaden ergeben sich hierbei unterschiedliche Anforderungen in dem Farbbild des Verbundfadens. Hierbei besteht der Wunsch, eine Vermischung der Einzelfäden zu erzeugen, die weder zu einem dominanten Hervortreten der Einzelfaden, noch zu einem völligen Vermischen der Einzelfäden in dem Verbundfaden führt. Insbesondere das dominante Hervortreten eines Farbanteils in dem Verbundfaden kann - wenn dieses zu lang ist - zu sogenannten "Flammen" führen, wie langgestreckte Anteile gleicher Farbe benannt sind. Derartige Flammen sind jedoch in den meisten Fällen erwünscht.In producing a crimped composite yarn in a one-step manufacturing process, a plurality of synthetic monofilaments are first extruded, cooled, and drawn, respectively, as a plurality of rope-shaped filaments. The individual threads in this case have different properties, preferably different colors, so that the coloring of the composite thread is determined by mixing the individual threads. Depending on the application for the composite thread, this results in different requirements in the color image of the composite thread. There is a desire to produce a mixing of the individual threads, which leads neither to a dominant emergence of the monofilament, nor to a complete mixing of the individual threads in the composite thread. In particular, the dominant emergence of a color component in the composite thread can - if this is too long - lead to so-called "flames" as elongated portions of the same color are named. However, such flames are desirable in most cases.

Es ist nun Aufgabe der Erfindung, ein Verfahren und eine Vorrichtung der gattungsgemäßen Art derart weiterzubilden, dass der Verbundfaden mit einer möglichst hohen Flexibilität in der Farbgestaltung von einer Mischfarbe bis hin zu einer Farbtrennung herstellbar ist.It is an object of the invention to develop a method and a device of the generic type such that the composite thread with the highest possible flexibility in the color design of a mixed color to a color separation can be produced.
Ein weiteres Ziel der Erfindung liegt darin, eine reproduzierbare Einstellbarkeit für das Farbbild des Verbundfadens zu ermöglichen.Another object of the invention is to provide a reproducible adjustability for the color image of the composite thread.
Diese Aufgabe wird erfindungsgemäß durch ein Verfahren mit den Merkmalen nach Anspruch 1 sowie durch eine Vorrichtung mit den Merkmalen nach Anspruch 12 gelöst.This object is achieved by a method with the features of
Vorteilhafte Weiterbildungen der Erfindung sind durch die Merkmale und Merkmalskombinationen der jeweiligen Unteransprüche definiert.Advantageous developments of the invention are defined by the features and feature combinations of the respective subclaims.
Die Erfindung liegt die Erkenntnis zugrunde, dass das Verwirbeln von multifilen Fäden mit sehr unterschiedlicher Wirkung einsetzbar ist. So kann das Verwirbeln eines multifilen Fadens dazu genutzt werden, um eine Vermengung oder eine Verknotung der Filamente des Fadens zu erzeugen. Damit ist die Intensität des Fadenschlusses, die sich im wesentlichen auch auf den jeweiligen Behandlungsschritt an dem Faden richtet, bestimmt. Hier setzt nun die Erfindung ein, die eine mehrfache Verwirbelung zumindest eines der multifilen Fäden vorsieht. Damit kann die speziell bis zum Kräuseln der Einzelfäden durchgeführten Behandlungsschritte mit individuell eingestellten Verwirbelungen zur Bildung eines Fadenschlusses durchgeführt werden. Hierzu wird zumindest einer der multifilen Einzelfäden vor dem Kräuseln in mehreren Vorstufen mehrmals verwirbelt. Ein weitere Vorteil der Erfindung ist dadurch gegeben, dass das gemeinsame Texturieren der Einzelfäden zu dem Verbundfaden beibehalten werden kann. Allein die mehrfache Verwirbelung der Einzelfäden ermöglicht eine flexible Gestaltung der Farbgebung in dem Verbundfaden. So lassen sich zur Einstellung einer hohen Farbseparierung jeder der Einzelfäden in mehreren Vorstufen verwirbeln. Um Mischerscheinungen in dem Verbundfaden zu erhalten, wird vorzugsweise nur einer der multifilen Einzelfäden in mehrere Vorstufen verwirbelt.The invention is based on the finding that the swirling of multifilament threads can be used with very different effects. Thus, the swirling of a multifilament yarn can be used to create a blending or knotting of the filaments of the yarn. Thus, the intensity of the thread conclusion, which is essentially also directed to the respective treatment step on the thread, determined. This is where the invention begins, which provides for multiple turbulences of at least one of the multifilament yarns. In this way, the treatment steps carried out, in particular, until the individual threads have been crimped, can be carried out with individually adjusted turbulences to form a thread closure. For this purpose, at least one of the multifilament monofilaments is vortexed several times before crimping in several preliminary stages. A further advantage of the invention is given by the fact that the common texturing of the monofilaments can be maintained to the composite thread. Just the multiple turbulence of the individual threads allows a flexible design of the coloring in the composite thread. Thus, to set a high color separation, each of the individual threads can be swirled in several preliminary stages. In order to obtain mixing phenomena in the composite thread, preferably only one of the multifilament monofilaments is swirled into a plurality of precursors.
Die Verfahrensvariante, bei welcher jeder der multifilen Einzelfäden in einer ersten Vorstufe vor dem Verstrecken separat verwirbelt wird, zeichnet sich dadurch aus, dass die Einzelfäden in der Verstreckeinrichtung mit hoher Laufruhe und geringem Abstand zueinander durch die Verstreckeinrichtung führbar sind. Hierbei kann die in der ersten Vorstufe eingebrachte Verwirbelung der Einzelfäden ausschließlich darauf abgestellt sein, einen für das Verstrecken der Einzelfäden optimalen Fadenschluß zu erhalten.The method variant, in which each of the multifilament monofilaments is vortexed separately in a first precursor before being drawn, is characterized from that the individual threads in the drawing device with high smoothness and small distance from each other by the drawing device can be guided. In this case, the swirling of the individual threads introduced in the first preliminary stage can be exclusively geared to obtaining an optimum thread closure for the stretching of the individual threads.
Um spezielle Farbmischungen oder Farbseparierungen in dem Verbundfaden zu erhalten, ist die Verfahrensvariante bevorzugt verwendet, bei welcher zumindest einer der Einzelfäden oder alle Einzelfäden in einer zweiten Vorstufe nach dem Verstrecken separat verwirbelt werden. Hierbei kann der durch die Verwirbelung an den Einzelfäden erzeugte Fadenschluß allein auf die nachfolgende gemeinsame Kräuselung der Einzelfäden abgestellt sein.In order to obtain special color mixtures or color separations in the composite thread, the method variant is preferably used, in which at least one of the individual threads or all individual threads are separately entangled in a second preliminary stage after stretching. In this case, the thread closure produced by the turbulence on the individual threads can be turned off solely on the subsequent common crimping of the individual threads.
Die Einstellbarkeit und die Bandbreite der Farbgebung des Verbundfadens lässt sich dadurch auch verbessern, indem die Einzelfäden in zumindest einer der Vorstufen mit jeweils unterschiedlichen Druckluftstellwerten einer Druckluftzufuhr verwirbelt werden. So können an den parallel geführten Einzelfäden unterschiedliche Verwirbelungsgrade eingestellt werden. Wird beispielsweise ein Verbundfaden gewünscht, welcher neben einer dominanten Einzelfarbe eine zweite Komponente als Mischfarbe aufweisen sollte, lässt sich der die Farbe bestimmende Einzelfaden mit relativ hohen Druckluftstellwerten verwirbeln. Hierbei ist die Höhe der Druckluftstellwerte proportional der im Faden erzeugten Flechtknoten zu sehen.The adjustability and the bandwidth of the coloring of the composite thread can also be improved by swirling the individual threads in at least one of the preliminary stages, each with different compressed air control values of a compressed air supply. Thus, different Verwirbelungsgrade can be adjusted at the parallel guided individual threads. If, for example, a composite thread is desired which should have a second component as a mixed color in addition to a dominant single color, the color-determining single thread can be swirled with relatively high compressed air control values. Here, the height of the compressed air control values is proportional to the braiding node produced in the thread.
Es ist jedoch auch möglich, die Verwirbelung der Einzelfäden in den Vorstufen mit jeweils unterschiedlichen Druckluftstellwerten der Druclckuftzuführungen auszuführen. So wird zum Verstrecken der Fäden ein geringerer Fadenschluss benötigt, um das einzelne Verziehen der Filamente nicht zu behindern. Demgegenüber wird für die gemeinsame Kräuselung der Einzelfäden eine auf die Farbstellung abgestellte Verwirbelung gewünscht.However, it is also possible to carry out the turbulence of the monofilaments in the preliminary stages, each with different compressed air control values of the pressure air feeds. Thus, a lesser thread closure is needed to stretch the threads, so as not to hinder the individual distortion of the filaments. In contrast, a parked on the color position swirling is desired for the common crimping of the individual threads.
Ebenso kann beispielsweise in der zweiten Vorstufe eine Pulsung des Druckes zu Verwirbelung durchgeführt werden, um die Farbvermischung zu variieren. So lassen sich besondere Garneffekte zur Herstellung von Fancy-Garnen herstellen.Likewise, for example, in the second preliminary stage, a pulsation of the pressure to turbulence can be carried out in order to vary the color mixture. This makes it possible to produce special yarn effects for the production of fancy yarns.
Zur Intensivierung der Verwirbelungsbehandlung vor dem Kräuseln der Einzelfäden hat sich die Verfahrensvariante besonders bewährt, bei welcher die multifilen Einzelfäden durch eine beheizte Druckluft verwirbelt werden. Alternativ ist es jedoch auch möglich, den Einzelfaden vor dem Verwirbeln zu beheizen. Dabei konnten sowohl Einflüsse auf die erzeugte Verflechtung der Filamente in den Einzelfäden als auch Auswirkungen auf Kräuselung des Verbundfadens festgestellt werden.To intensify the Verwirbelungsbehandlung before crimping the monofilaments, the process variant has proven particularly useful in which the multifilament monofilaments are swirled by a heated compressed air. Alternatively, however, it is also possible to heat the monofilament before swirling. In this case, it was possible to determine influences on the generated entanglement of the filaments in the monofilaments as well as effects on crimping of the composite thread.
Um die für das Kräuseln der Einzelfäden maßgeblichen Fadenspannungen unabhängig von den Fadenspannungen der vorgeordneten Verwirbelung einstellen zu können, ist die Verfahrensvariante besonders vorteilhaft, bei welcher die Einzelfäden vor dem Kräuseln mit mehrfache Umschlingung an einer Galetteneinheit geführt und in einem Fadenstück der Umschlingungen vor Ablauf von der Galetteneinheit verwirbelt werden.In order to adjust the decisive for the crimping of the individual filaments thread tensions independent of the thread tensions of the upstream turbulence, the process variant is particularly advantageous in which the monofilaments before curling with multiple wrapping led to a godet unit and in a thread piece of wraps before expiration of the Galetteneinheit be swirled.
Bei Verwendung beheizter Galetten lässt sich dabei vorteilhaft gleichzeitig eine temperierte Verwirbelung an dem Einzelfaden durchführen.When using heated godets can thereby advantageously simultaneously perform a tempered turbulence on the monofilament.
Um den für die endgültige Weiterverarbeitung des Verbundfadens erforderlichen Fadenschluss zu erhalten, wird der Verbundfaden nach dem Kräuseln der Einzelfäden und vor einem Aufwickeln zu einer Spule getangelt, wobei die durch die Verwirbelung in den Vorstufen sowie durch die Kräuselung der Einzelfäden erzeugte Farbgebung des Verbundfadens im wesentlichen erhalten bleibt.In order to obtain the thread closure required for the final further processing of the composite thread, the composite thread after the crimping of the individual threads and before winding wound into a coil, wherein the color produced by the vortex swirling in the precursors and by the crimping of the individual threads of the composite thread substantially preserved.
Das erfindungsgemäße Verfahren ist insbesondere zur Herstellung von einem Verbundfaden geeignet, der aus mehreren vorzugsweise unterschiedlichen Teilfäden gebildet wird. Die Erfindung beschränkt sich jedoch nicht auf Teilfäden unterschiedlicher Beschaffenheit, da insbesondere eine individuelle Vorbehandlung der Einzelfäden auch vorteilhaft bei Verbundfäden genutzt werden kann, die aus identischen Teilfäden gebildet sind. Dabei stehen insbesondere Strukturmerkmale der Einzelfäden im Vordergrund, die durch die unterschiedliche in zwei Stufen durchgeführte Vorverwirbelung erzeugt werden können.The inventive method is particularly suitable for the production of a composite thread, which is formed from a plurality of preferably different partial threads. However, the invention is not limited to partial threads of different Texture, since in particular an individual pretreatment of the monofilaments can also be used advantageously in composite threads, which are formed of identical partial threads. In particular, structural features of the monofilaments are in the foreground, which can be generated by the different Vorverwirbelung carried out in two stages.
Das erfindungsgemäße Verfahren ist auch dazu geeignet, nach einer separaten Verwirbelung in einer ersten Stufe alle Einzelfäden gemeinsam in der zweiten Vorstufe zu verwirbeln. Durch die mehrstufige Verwirbelung vor dem Texturieren bietet die Erfindung eine sehr hohe Flexibilität in der Vorbehandlung der Einzelfäden vor dem Texturieren. So ist es auch möglich, dass die Einzelfäden in der ersten Vorstufe gemeinsam und in der zweiten Vorstufe getrennt verwirbelt werden.The inventive method is also suitable, after a separate turbulence in a first stage to swirl all the individual threads together in the second precursor. Due to the multi-stage turbulence before texturing, the invention offers a very high degree of flexibility in the pretreatment of the monofilaments before texturing. Thus, it is also possible that the monofilaments in the first precursor are mixed together and in the second precursor are vortexed separately.
Desweiteren ist das erfindungsgemäße Verfahren nicht darauf beschränkt, dass die Einzelfäden gemeinsam gekräuselt werden. Grundsätzlich besteht auch die Möglichkeit, dass vor dem Zusammenführen der Einzelfäden jeder der Einzelfäden separat texturiert wird. Eine weitere Verfahrensvariante lässt sich dabei auch derart ausführen, so dass nach einer gemeinsamen oder separaten Texturierung und Zusammenführung der Einzelfäden zu dem Verbundfaden der Verbundfaden nach dem Abkühlen wieder zu Teilfäden separiert wird, die anschließend gemeinsam vor dem Aufwickeln zu dem endgültigen Verbundfaden verwirbelt werden. Eine derartige Verfahrensvariante lässt sich bei unterschiedlich eingefärbten Einzelfäden nutzen, um zusätzliche Farbeinstellungen zu erhalten.Furthermore, the inventive method is not limited to that the individual threads are crimped together. In principle, there is also the possibility that each of the individual threads is textured separately before merging the individual threads. A further variant of the method can also be carried out in such a way that, after a common or separate texturing and merging of the individual threads into the composite thread, the composite thread is separated again into partial threads after cooling, which are subsequently swirled together before being wound up into the final composite thread. Such a variant of the method can be used with differently dyed individual threads in order to obtain additional color settings.
Zur Durchführung des erfindungsgemäßen Verfahrens weist die erfindungsgemäße Vorrichtung eine aus mehreren Verwirbelungseinheiten gebildete Verwirbelungseinrichtung auf, wobei die Verwirbelungseinheiten im Fadenlauf der Einzelfäden hintereinander angeordnet sind.To carry out the method according to the invention, the device according to the invention has a swirling device formed from a plurality of swirling units, wherein the swirling units are arranged one behind the other in the yarn path of the monofilaments.
Um zwischen den einzelnen Verwirbelungsstufen Behandlungsschritte an den Einzelfäden durchführen zu können, ist vorteilhaft eine erste Verwirbelungseinheit der Verstreckeinrichtung vorgeordnet, wobei die erste Verwirbelungseinheit zu jedem der Einzelfäden jeweils eine Verwirbelungsdüse aufweist.In order to be able to carry out treatment steps on the monofilaments between the individual swirling stages, a first swirling unit of the stretching unit is advantageously arranged upstream, wherein the first swirling unit has a swirling nozzle for each of the individual threads.
Eine mit mehreren Verwirbelungsdüsen zweite Verwirbelungseinheit ist dabei vorteilhaft zwischen der Verstreckeinrichtung und der Kräuseleinrichtung angeordnet.A second turbulence unit with a plurality of fluidizing nozzles is advantageously arranged between the drawing device and the curling device.
Um die Verwirbelung der Einzelfäden in den einzelnen Vorstufen mit unterschiedlichen Druckluflstellwerten vornehmen zu können, sind die Verwirbelungsdüsen jeweils eine steuerbare Druckluftzuführung zugeordnet. Dabei kann die Druckluftzuführung sowohl gleichzeitig mehrere Verwirbelungsdüsen versorgen oder zur separaten Versorgung einer Verwirbelungsdüse eingesetzt werden.In order to be able to carry out the swirling of the individual threads in the individual preliminary stages with different compressed air setting values, the swirling nozzles are each assigned a controllable compressed air supply. In this case, the compressed air supply both simultaneously supply a plurality of swirling nozzles or can be used for the separate supply of a swirling nozzle.
Um die zuvor durch eine thermische Verwirbelung hervorgerufenen Sondereffekte zu erhalten, lässt sich die erfindungsgemäße Vorrichtung derart erweitern, dass zumindest einem der Verwirbelungseinheiten ein Heizmittel zugeordnet ist, durch welche eine Druckluft beheizbar ist.In order to obtain the special effects previously caused by thermal turbulence, the device according to the invention can be expanded in such a way that at least one of the turbulence units is assigned a heating means by which compressed air can be heated.
Alternativ könnte jedoch der Verwirbelungseinheit eine Heizeinrichtung vorgeordnet sein, durch welche die Einzelfäden beheizbar sind.Alternatively, however, the turbulence unit could be preceded by a heating device, by means of which the individual filaments can be heated.
Zur Durchführung einer unabhängigen Fadenspannungseinstellung beim Kräuseln und beim Verwirbeln der Einzelfäden ist die erfindungsgemäße Vorrichtung bevorzugt verwendet, bei welcher die Verstreckeinrichtung eine der Kräuseleinrichtung vorgeordnete Galetteneinheit aufweist, an welcher die Einzelfäden mit mehrfacher Umschlingung geführt sind, und bei welcher die Verwirbelungsdüsen der zweiten Verwirbelungseinheit der Galetteneinheit derart zugeordnet sind, dass die Einzelfäden vor Ablauf von der Galetteneinheit verwirbelbar sind.In order to carry out an independent thread tension adjustment during curling and during swirling of the monofilaments, the device according to the invention is preferably used, in which the stretching device has a godet unit upstream of the curling device, on which the monofilaments are guided with multiple wrapping, and in which the swirling nozzles of the second turbulence unit of the godet unit are assigned such that the individual threads are vortexed before expiry of the godet unit.
Bei der Anordnung der Verwirbelungsdüsen der zweiten Verwirbelungseinheit in einem Umschlingungsast zwischen zwei Galetten lässt sich bei der Anordnung der Verwirbelungsdüsen in der letzen Umschlingung eine Absenkung der Fadenspannung in der Verwirbelung dadurch einstellen, dass die Einzelfäden bei Ablauf von der Galetteneinheit auf einen Stufensprung der Galette mit reduziertem Durchmesser geführt werden. Grundsätzlich ist jedoch bei Anordnung der Verwirbelungsdüse jeder Umschlingungsast zwischen dem Galettenduo geeignet, um eine Verwirbelung in zweiter Vorstufe ausführen zu können.In the arrangement of the Verwirbelungsdüsen the second Verwirbelseinheit in a Umschlingungsast between two Godets can be set in the arrangement of the Verwirbelungsdüsen in the last wrap a lowering of the thread tension in the swirl that the individual threads at expiration of the godet unit to a step jump of the godet with reduced Diameter to be guided. In principle, however, any Umschlingungsast between the godet duo is suitable for the arrangement of the Verwirbelungsdüse in order to carry out a swirling in the second stage.
Um zusätzliche thermische Effekte beim Verwirbeln der Filamente zu erhalten, lässt sich die Galetteneinheit gemäß einer vorteilhaften Weiterbildung der Vorrichtung zumindest durch zwei angetriebene Galetten bilden, bei welcher zumindest eine der Galetten beheizbar ausgebildet ist.In order to obtain additional thermal effects in the swirling of the filaments, the godet unit can be formed according to an advantageous development of the device at least by two driven godets, wherein at least one of the godets is formed heatable.
Zur endgültigen Herstellung eines Fadenschlusses in dem Verbundfaden ist zwischen der Kräuselvorrichtung und einer zum Aufspulen des Verbundfadens vorgesehene Aufwickeleinrichtung eine Tangeleinrichtung angeordnet.For the final production of a thread closure in the composite thread a Tangeleinrichtung is arranged between the crimping device and a winding device provided for winding the composite thread.
Zur Herstellung einer intensiven und gleichmäßigen Kräuselung der Einzelfäden hat sich insbesondere die Vorrichtungsvariante bewährt, bei welcher die Kräuseleinrichtung durch eine Förderdüse und eine der Förderdüse zugeordnete Stauchkammer aufweist. Dabei werden die Einzelfäden mittels der Förderdüse gemeinsam in die Stauchkammer gefördert und zu einem Fadenstopfen aufgestaucht.In order to produce an intensive and uniform crimping of the monofilaments, the device variant in which the crimping device has a stuffer box and a delivery nozzle assigned to the delivery nozzle has proved particularly useful. The individual threads are conveyed together by means of the delivery nozzle in the stuffer box and popped up to a yarn plug.

Hierzu ist am Ausgang der Kühlleinrichtung 4 eine Präparationseinrichtung 7 sowie die den Einzelfäden 6.1, 6.2 und 6.3 zugeordnete Fadenführer 5.1, 5.2 und 5.3 vorgesehen.For this purpose, a
Um die Einzelfäden 6.1, 6.2 und 6.3 von den Spinndüsen 3.1, 3.2 und 3.3 abzuziehen, ist eine Streckeinrichtung 10 vorgesehen, die zumindest eine Abzugsgaletteneinheit 18 (gestrichelt dargestellt) enthält. Hierbei werden die Einzelfäden 6.1, 6.2 und 6.3 im parallelen Lauf durch die Streckeinrichtung 10 geführt. Die Einzelfäden können dabei durch eine Abzugsgaletteneinheit gemeinsam abgezogen werden oder alternativ jeweils durch Einzellieferwerke, die den Einzelfäden zugeordnet sind.In order to remove the individual threads 6.1, 6.2 and 6.3 from the spinnerets 3.1, 3.2 and 3.3, a stretching
Nach dem Abziehen und Verstrecken der Einzelfäden 6.1, 6.2 und 6.3 durch die Streckeinrichtung 10 werden die Einzelfäden 6.1, 6.2 und 6.3 in einer Kräuseleinrichtung 11 zusammengeführt und gemeinsam zu einem Verbundfaden 21 verbunden.After stripping and stretching of the individual threads 6.1, 6.2 and 6.3 by the stretching
Die Kräuseleinrichtung 11 wird in diesem Ausfübrungsbeispiel durch eine Förderdüse 15 und eine mit der Förderdüse 15 zusammenwirkende Stauchkammer 16 gebildet. Die Förderdüse 15 ist mit einer Druckquelle (nicht dargestellt) verbunden, durch welche ein Fördermedium der Förderdüse 15 zugeführt wird. Durch das Fördermedium werden die Einzelfäden 6.1, 6.2 und 6.3 in die Förderdüse 15 eingezogen und anschließend in der Stauchkammer 16 zu einem Fadenstopfen aufgestaucht. Hierbei tritt eine Teilvermengung der Einzelfäden 6.1 bis 6.3 ein. Der vorzugsweise durch eine heißes Fördermedium erzeugte Fadenstopfen 22 wird anschließend zu einer Kühltrommel 17 geführt und abgekühlt.The crimping
Zur Vorbehandlung der Einzelfäden 6.1 bis 6.3 sind zwischen der Präparationseinrichtung 7 und der Streckeinrichtung 10 eine erste Verwirbelungseinheit 8.1 sowie zwischen der Streckeinrichtung 10 und der Kühleinrichtung 11 eine zweite Verwirbelungseinheit 8.2 angeordnet. Die erste Verwirbelungseinheit 8.1 weist mehrere Verwirbelungsdüsen 9.1, 9.2 und 9.3 auf, die jeweils den Einzelfäden 6.1, 6.2 und 6.3 zugeordnet sind. Jede der Verwirbelungsdüsen 9.1, 9.2 und 9.3 enthält einen Fadenkanal, durch welchen der Einzelfaden geführt ist. In dem Fadenkanal mündet seitlich ein Druckkanal, um ein Fluid vorzugsweise eine Druckluft mit hoher Energie in den Fadenkanal einzuleiten. Die Druckkanäle sind über eine Druckluftzuführung 12.1 und ein Druckstellmittel 14.1 mit einer Druckquelle verbunden. Zur Einstellung eines Druckluftstellwertes ist das Druckstellmittel 14.1 mit einer Steuereinrichtung 24 gekoppelt.For the pretreatment of the individual threads 6.1 to 6.3, a first swirling unit 8.1 and a second swirling unit 8.2 between the stretching
Der Aufbau der Verwirbelungsdüsen 9.1, 9.2 oder 9.3 ist grundsätzlich bekannt und beispielsweise in der
Die der Kräuseleinrichtung 11 vorgeordnete zweite Verwirbelungseinheit 8.2 weist ebenfalls mehrere Verwirbelungsdüsen auf, die mit dem Bezugszeichen 9.4 bis 9.6 gekennzeichnet sind. Der Aufbau der Verwirblungsdüsen 9.4 bis 9.6 der zweiten Verwirbelungseinheit 8.2 ist im wesentlichen identisch zu dem Aufbau der Verwirbelungsdüsen 9.1 bis 9.3 der ersten Verwirbelungseinheit 8.1. Die Verwirbelungsdüsen 9.4 bis 9.6 sind über die Druckluftzuführung 12.2 und dem Druckstellmittel 14.2 mit einer hier nicht dargestellten Druckquelle verbunden. Das Druckstellmittel 14.2 ist zur Einstellung und Veränderung eines Druckluftstellwertes mit der Steuereinrichtung 24 gekoppelt. Die Verwirbelungseinheiten 8.1 und 8.2 können somit unabhängig voneinander zum Verwirbeln der Einzelfäden 6.1 bis 6.3 betrieben werden.The second turbulence unit 8.2 upstream of the crimping
Zur Nachbehandlung des durch die Einzelfäden 6.1 bis 6.3 gebildeten gekräuselten Verbundfadens 21 ist der Kräuseleinrichtung 11 eine Tangeleinrichtung 19 nachgeordnet Innerhalb der Tangeleinrichtung 19 erhält der Verbundfaden 21 eine letzte für die Weiterbearbeitung erforderliche Fadenschlussbehandlung.For post-treatment of the crimped
Nach dem Tangeln wird der Verbundfaden 21 von der Aufwickeleinrichtung 20 aufgenommen und zu einer Spule 23 gewickelt.After tangling, the
Hierbei dient die Aufwickeleinrichtung 20 gleichzeitig als Abzugsorgan um den gekräuselten Verbundfaden 21 aus dem Fadenstopfen 22 abzuziehen. Um die Fadenspannungen zum Aufwickeln und zum Tangeln des Verbundfadens 21 einstellen zu können, lässt sich der Verbundfaden 21 auch durch eine Abzugsgalette aus dem Fadenstopfen 22 abziehen und durch eine weitere der Tangeleinrichtung 19 nachgeordnete Galetteneinheit zur Aufwickeleinrichtung 20 führen. Die Ausgestaltung der Einrichtungen in der Nachbehandlungszone wirkt sich jedoch auf das erfindungsgemäße Verfahren nicht aus, so dass beliebige Prozessaggregate und Behandlungsstufen an dem Verbundfaden 21 bis zum Aufwickeln zu einer Spule 23 ausführbar sind.In this case, the take-up
Bei dem in
Jeder der Filamentbündel 13.1, 13.2 und 13.3 wird zu einem Einzelfaden 6.1, 6.2 und 6.3 zusammengeführt. Dazu wird den Filamentbündeln 13.1, 13.2 und 13.3 durch die Präparationseinrichtung 7 jeweils ein Präparationsmittel zugeführt und durch die Fadenführer 5.1, 5.2 und 5.3 zu den jeweiligen Einzelfäden verbunden.Each of the filament bundles 13.1, 13.2 and 13.3 is merged into a single thread 6.1, 6.2 and 6.3. For this purpose, the filament bundles 13.1, 13.2 and 13.3 are each supplied with a preparation medium by the
Zur weiteren Behandlung der Einzelfäden 6.1 bis 6.3 erfolgt in einer ersten Vorstufe unmittelbar nach dem Präparieren eine erste Verwirbelung durch die Verwirbelungseinheit 8.1. Hierzu wird jeder der Einzelfäden 6.1 bis 6.3 durch eine Verwirbelungsdüse 9.1 bis 9.3 geführt. Die Verwirbelungseinheit 8.1 weist dabei einen Druckstellwert der zugeführten Druckluft auf, welcher zu einer Verflechtung der den Einzelfaden bildenden Filamente führt. Hierbei wird einerseits eine Vergleichmäßigung des Präparationsauftrages erreicht und andererseits ein für die nachfolgende Galettenführung in der Streckeinrichtung 10 erforderlicher Mindestfadenschluß hergestellt Bei Einstellung des Druckstellwertes ist darauf zu achten, dass keine zu intensive Verknotung der Filamente der Einzelfäden eintritt.For further treatment of the monofilaments 6.1 to 6.3, a first turbulence is performed by the turbulence unit 8.1 in a first preliminary stage immediately after preparation. For this purpose, each of the individual threads 6.1 to 6.3 is guided through a swirl nozzle 9.1 to 9.3. In this case, the swirling unit 8.1 has a pressure set value of the supplied compressed air, which leads to an interlacing which leads to the filament forming filaments.

Nachdem die Einzelfäden 6.1 bis 6.3 ausgezogen und verstreckt sind, erfolgt eine zweite Verwirbelung der Einzelfäden 6.1 bis 6.3 in der zweiten Vorstufe durch die Verwirbelungseinheit 8.2. In der Verwirbelungseinheit 8.2 werden die Einzelfäden 6.1 bis 6.3 jeweils separat durch die Verwirbelungsdüsen 9.4 bis 9.6 geführt und verwirbelt. Hierbei wird die in den Einzelfäden 6.1 bis 6.3 eingebrachte Verflechtung der Filamente derart gewählt, dass ein eine bestimmte Vermengung bei der Kräuselung der Einzelfäden 6.1 bis 6.3 zu dem Verbundfaden 2.1 entsteht Insbesondere bei der Herstellung eines mehrfarbig gekräuselten Verbundfadens kann damit die Farbgebung des Verbundfadens 21 in weiten Grenzen beeinflusst werden. So lässt sich beispielsweise ein Verbundfaden 21 mit starker Farbseparierung dadurch erzeugen, dass bei der Verwirbelung in der zweiten Verwirbelungseinheit 8.2 ein relativ hoher Druckstellwert der zugeführten Druckluft eingesellt wird. Damit wird eine intensive Verflechtung der Filamente des Einzelfadens erzeugt, die selbst bei der anschließenden Kräuselbehandlung wenig gelöst werden kann. Umgekehrt lässt sich durch Einstellung eines niedrigen Druckstellwertes in der Verwirbelungseinheit 8.2 erreichen, dass der Verbundfaden 21 eine mehr oder weniger starke Mischfarbe aufweist.After the monofilaments 6.1 to 6.3 are pulled out and stretched, a second swirling of the monofilaments 6.1 to 6.3 in the second preliminary stage by the swirling 8.2. In the swirling unit 8.2, the individual threads 6.1 to 6.3 are each guided and swirled separately through the swirling nozzles 9.4 to 9.6. In this case, the entanglement of the filaments introduced in the individual threads 6.1 to 6.3 is selected so that a certain mixing occurs during the crimping of the individual threads 6.1 to 6.3 to form the composite thread 2.1 Thus, in particular in the production of a multicolored crimped composite thread, the coloring of the
Nach dem Verwirbeln in der zweiten Vorstufe werden die Einzelfäden 6.1 bis 6.3 gemeinsam gekräuselt und zu dem Verbundfaden 21 zusammengeführt. Hierzu werden die Einzelfäden 6.1 bis 6.3 durch die Förderdüse 15 mit einem Förderfluid in eine angrenzende Stauchkammer 16 gefördert. Innerhalb der Stauchkammer 16 legen sich die Filamente der Einzelfäden 6.1 bis 6.3 in Schlingen und Bögen zu einem Fadenstopfen 22, der nach einer thermischen Behandlung zu dem gekräuselten Verbundfaden 21 aufgelöst wird. Zur Herstellung eines endgültigen Fadenschlusses wird der Verbundfaden 21 vor dem Aufwickeln zu einer Spule 23 in der Tangeleinrichtung 19 getangelt.After vortexing in the second preliminary stage, the individual threads 6.1 to 6.3 are co-crimped together and combined to form the
