Definitions
- the invention relates to a device for treating at least one running multifilament yarn with a blown medium, with a continuous yarn channel which is circular in cross-section and has a cylindrical central section, into which a number of blown medium supply bores open laterally.
- blowing medium generally compressed air
- the blowing medium serves to change the mutual spatial arrangement of the filaments in the multifilament yarn, to change the appearance and feel of the yarn and / or to improve the cohesion of the filaments in the yarn for further processing.
- the known devices are, for example, texturing devices to which one or more multifilament yarns are fed at a speed which is higher than the speed at which the yarn is drawn out of the device.
- the speed difference usually referred to as tradition, can be about 10 to 30%.
- the yarns fed are generally smooth yarns, on which the blowing medium in the yarn channel from one or more blowing medium supply holes inclined to the axis of the yarn channel impinges.
- the treated textured yarn has a compact core in which the filaments are closely intertwined and from which filament loops protrude.

This gives the filaments the necessary cohesion for further processing of the yarn. Filament loops practically do not arise.
- the multifilament yarn supplied can be smooth or, for example, false twist textured. If it is elastic, then the yarn is still elastic after treatment in the intermingling device.
- the non-uniform structure of the yarn with the discrete interlacing knots separated by non-interlaced areas, can interfere with certain applications.
- the separate intermingling knots do not completely disappear during further processing (e.g. during weaving or knitting and possibly finishing) and can produce undesired moiré effects in the end product.
- the invention has now set itself the task of designing the device specified at the outset in such a way that multifilament yarns can be treated in such a way that the filaments of the multifilament yarn or multifilament yarns fed in are interwoven uniformly along the length of the yarn, without forming separate interlacing knots and form practically no protruding filament loops.
- the device according to the invention is characterized in that the number of blowing medium supply bores is three and that these bores are arranged at equal angular intervals from one another such that their axes align the axis of the yarn channel at a common point under each Cut angles from 15 to 40 °.

Description
Die Erfindung bezieht sich auf eine Vorrichtung zum Behandeln wenigstens eines laufenden Multifilamentgarns mit einem Blasmedium, mit einem durchgehenden, im Querschnitt kreisrunden Garnkanal, der einen zylindrischen mittleren Abschnitt aufweist, in welchen eine Anzahl Blasmedium-Zufuhrbohrungen seitlich einmünden.The invention relates to a device for treating at least one running multifilament yarn with a blown medium, with a continuous yarn channel which is circular in cross-section and has a cylindrical central section, into which a number of blown medium supply bores open laterally.
Solche Vorrichtungen, in denen ein Blasmedium, in der Regel Druckluft, im wesentlichen mit Umgebungstemperatur durch die Zufuhrbohrungen auf ein durch den Garnkanal laufendes Multifilamentgarn geblasen wird, sind in zahlreichen Ausführungen bekannt. Das Blasmedium dient dazu, die gegenseitige räumliche Anordnung der Filamente im Multifilamentgarn zu ändern, um das Aussehen und den Griff des Garns zu verändern und/oder um den Zusammenhalt der Filamente im Garn für die Weiterverarbeitung zu verbessern.Devices of this type, in which a blowing medium, generally compressed air, are blown at ambient temperature essentially through the feed bores onto a multifilament yarn running through the yarn channel, are known in numerous designs. The blowing medium serves to change the mutual spatial arrangement of the filaments in the multifilament yarn, to change the appearance and feel of the yarn and / or to improve the cohesion of the filaments in the yarn for further processing.
Die bekannten Vorrichtungen (siehe US-A-3 638 291) sind beispielsweise Texturiervorrichtungen, denen ein Multifilamentgarn oder mehrere Multifilamentgarne mit einer Geschwindigkeit zugeführt werden, die höher ist als die Abzugsgeschwindigkeit des Garns aus der Vorrichtung. Der Geschwindigkeitsunterschied, in der Regel als Ueberlieferung bezeichnet, kann etwa 10 bis 30% betragen. Die zugeführten Garne sind in der Regel glatte Garne, auf welche das Blasmedium im Garnkanal aus einer oder mehreren zur Achse des Garnkanals geneigten Blasmedium-Zufuhrbohrungen auftrifft. Das behandelte texturierte Garn hat einen kompakten Kern, in welchem die Filamente eng miteinander verflochten sind und von welchem Filamentschlingen abstehen. Das Garn ist nicht elastisch. Auch sind für manche Anwendungen die von der Oberfläche abstehenden Filamentschlingen nachteilig, da sie leicht hängenbleiben können.The known devices (see US-A-3 638 291) are, for example, texturing devices to which one or more multifilament yarns are fed at a speed which is higher than the speed at which the yarn is drawn out of the device. The speed difference, usually referred to as tradition, can be about 10 to 30%. The yarns fed are generally smooth yarns, on which the blowing medium in the yarn channel from one or more blowing medium supply holes inclined to the axis of the yarn channel impinges. The treated textured yarn has a compact core in which the filaments are closely intertwined and from which filament loops protrude. The yarn is not elastic. The filament loops protruding from the surface are also disadvantageous for some applications, since they can easily get caught.
Andere bekannte Vorrichtungen werden lungsvorrichtungen genannt. In diesen werden ein Multifilamentgarn oder mehrere Multifilamentgarne mit nur geringer Ueberlieferung, höchstens etwa 10%, durch den Garnkanal geführt, in welchem sie mit Blasmedium aus einer Blasmedium-Zufuhrbohrung beaufschlagt werden, deren Achse zur Achse des Garnkanals etwa senkrecht steht. Durch diese Behandlung entstehen im Garn in mehr oder weniger regelmässigen Abständen voneinander Verwirbelungsknoten, in denen die Filamente des Garns miteinander verflochten sind. Dadurch erhalten die Filamente den nötigen Zusammenhalt für die Weiterverarbeitung des Garns. Filamentschlingen entstehen praktisch nicht. Das zugeführte Multifilamentgarn kann glatt oder auch beispielsweise falschdralltexturiert sein. Wenn es elastisch ist, dann ist auch das Garn nach der Behandlung in der Verwirbelungsvorrichtung noch elastisch. Jedoch kann sich die ungleichförmige Struktur des Garns, mit den diskreten Verwirbelungsknoten, die durch unverwirbelte Stellen voneinander getrennt sind, für gewisse Anwendungen störend auswirken. Die voneinander getrennten Verwirbelungsknoten verschwinden bei der Weiterverarbeitung (z.B. beim Weben oder Wirken und ggf. Ausrüsten) nicht vollständig und können im Endprodukt unerwünschte Moiré-Effekte erzeugen.Other known devices are called lungs devices. In these, a multifilament yarn or several multifilament yarns with only a small amount Traditionally, at most about 10%, passed through the yarn channel in which they are supplied with blowing medium from a blowing medium supply bore, the axis of which is approximately perpendicular to the axis of the yarn channel. This treatment creates swirling nodes in the yarn at more or less regular intervals, in which the filaments of the yarn are intertwined. This gives the filaments the necessary cohesion for further processing of the yarn. Filament loops practically do not arise. The multifilament yarn supplied can be smooth or, for example, false twist textured. If it is elastic, then the yarn is still elastic after treatment in the intermingling device. However, the non-uniform structure of the yarn, with the discrete interlacing knots separated by non-interlaced areas, can interfere with certain applications. The separate intermingling knots do not completely disappear during further processing (e.g. during weaving or knitting and possibly finishing) and can produce undesired moiré effects in the end product.
Die Erfindung hat sich nun die Aufgabe gestellt, die eingangs angegebene Vorrichtung derart auszubilden, dass Multifilamentgarne darin so behandelt werden können, dass die Filamente des zugeführten Multifilamentgarns bzw. der zugeführten Multifilamentgarne auf der Länge des Garns gleichförmig, ohne Bildung voneinander getrennter Verwirbelungsknoten, miteinander verflochten werden und dabei praktisch keine abstehenden Filamentschlingen bilden.The invention has now set itself the task of designing the device specified at the outset in such a way that multifilament yarns can be treated in such a way that the filaments of the multifilament yarn or multifilament yarns fed in are interwoven uniformly along the length of the yarn, without forming separate interlacing knots and form practically no protruding filament loops.

Vorzugsweise besitzt der Garnkanal vor dem zylindrischen mittleren Abschnitt einen sich konisch verengenden Einlassabschnitt und nach dem zylindrischen mittleren Abschnitt einen sich trompetenförmig erweiternden Auslassabschnitt.The yarn channel preferably has a conically narrowing in front of the cylindrical central section Inlet section and after the cylindrical central section a trumpet-shaped widening outlet section.
Mit einer solchen Vorrichtung kann ein Garn mit den vorstehend angegebenen erwünschten Eigenschaften erhalten werden, wenn der Vorrichtung ein Multifilamentgarn oder Multifilamentgarne mit einer Ueberlieferung im Bereich von 0 bis höchstens 15% zugeführt werden und das behandelte Garn vom Auslass der Vorrichtung quer zur Achse des Garnkanals, vorzugsweise unter einem Winkel von annähernd 90° zur Garnkanalachse, abgezogen wird.With such a device, a yarn with the desired properties specified above can be obtained if the device is fed a multifilament yarn or multifilament yarns with a delivery in the range from 0 to at most 15% and the treated yarn from the outlet of the device transversely to the axis of the yarn channel, preferably at an angle of approximately 90 ° to the yarn channel axis.

Der in den Fig. 1 bis 3 dargestellte Körper besteht aus zwei aufeinanderliegenden Teilen 11 und 12. In einander zugekehrten Seitenflächen der beiden Teile 11 und 12 sind Ausnehmungen vorgesehen, die in der Betriebsstellung der beiden Teile, gemäss den Fig. 1 und 2, zusammen einen durchgehenden, im Querschnitt kreisrunden Garnkanal begrenzen, welcher aus einem sich konisch verengenden Einlassabschnitt 13, einem zylindrischen mittleren Abschnitt 14 und einem sich trompetenförmig erweiternden Auslassabschnitt 15 besteht. Der zylindrische mittlere Abschnitt 14 des Garnkanals hat einen Durchmesser von 1 bis 2 mm, vorzugsweise etwa 1,2 mm.The body shown in FIGS. 1 to 3 consists of two
In den zylindrischen mittleren Abschnitt 14 des Garnkanals münden seitlich drei Blasmedium-Zufuhrbohrungen 16, 17 und 18, die in gleichen Winkelabständen voneinander um die Achse des Garnkanals verteilt sind. Die Achsen der Bohrungen 16, 17 und 18 schneiden die Achse des Garnkanals 13, 14, 15 in einem gemeinsamen Punkt je unter einem Winkel im Bereich von 15 bis 40°, vorzugsweise 25 bis 35° und am besten etwa 30°. Die drei Bohrungen 16, 17 und 18 haben alle gleiche Durchmesser oder leicht unterschiedliche Durchmesser im Bereich von 0,4 bis 0,8 mm. Vorzugsweise haben alle drei Bohrungen einen gleichen Durchmesser im Bereich von 0,55 bis 0,65 mm, am besten etwa 0,6 mm.Three blowing medium supply bores 16, 17 and 18 open laterally into the
Dem Garnkanal 13, 14, 15 wird ein Multifilament-garn M1 oder mehrere Multifilamentgarne (nicht dargestellt) zugeführt. Die zugeführten Multifilamentgarne können glatte und/oder texturierte Garne aus z.B. Polyamid und/oder aus Polyester sein.A multifilament yarn M1 or more multifilament yarns (not shown) are fed to the
Den Blasmedium-Zufuhrbohrungen 16, 17 und 18 wird ein Blasmedium, in der Regel Druckluft mit Umgebungstemperatur, zugeführt aus einem Einlass 19 über eine Speisebohrung 20, die zur Bohrung 16 führt, und eine Speisebohrung 21, die zur Bohrung 18 und zu einer Kammer 22 führt, von welcher die Bohrung 17 ausgeht.The blowing medium supply bores 16, 17 and 18 are supplied with a blowing medium, generally compressed air at ambient temperature, from an
Dank der beschriebenen Geometrie, mit den drei Blasmedium-Zufuhrbohrungen 16, 17 und 18, die mit der Achse des Garnkanals 13, 14, 15 einen kleinen Winkel von weniger als 40° bilden, gelingt es, das zugeführte Multifilamentgarn M1 bzw. die zugeführten Multifilamentgarne so zu behandeln, dass nach der Behandlung ein kompaktes Multifilamentgarn M2 erhalten wird, in welchem die Einzelfilamente über die Länge des Garns gleichförmig eng miteinander verflochten sind, welches jedoch keine abstehenden Filamentschlingen aufweist. Voraussetzung für die Erzielung dieses Resultates ist lediglich, dass das Multifilamentgarn M1 bzw. die zu behandelnden Multifilamentgarne dem Garnkanal 13, 14, 15 je mit einer Ueberlieferung im Bereich von 0 bis höchstens 15%, vorzugsweise höchstens 10%, zugeführt werden und dass das behandelte Garn aus dem Auslass des Garnkanals wie dargestellt in einer Richtung quer zur Achse des Garnkanals abgezogen wird. Wenn mehrere Multifilamentgarne gleichzeitig zugeführt werden, kann die Ueberlieferung, d.h. der Prozentsatz, um den die Zufuhrgeschwindigkeit höher ist als die Abzugsgeschwindigkeit des behandelten Garns, bei allen zugeführten Garnen gleich oder auch bei verschiedenen zugeführten Garnen unterschiedlich sein, immer im angegebenen Bereich bis höchstens 15%.Thanks to the geometry described, with the three blowing
Der Körper der dargestellten bevorzugten Ausführungsform der erfindungsgemässen Vorrichtung besteht wie angegeben aus den beiden Teilen 11 und 12. Diese sind in einer in Fig. 3 schematisch angedeuteten Halterung 23 derart angeordnet, dass der eine Teil 12 bezüglich des anderen Teils 11 verschiebbar ist zwischen der Betriebsstellung gemäss Fig. 1 und 2 und einer Einfädelstellung gemäss Fig. 3. In der Betriebsstellung begrenzen die Ausnehmungen in den einander zugekehrten Seitenflächen der beiden Teile 11 und 12 wie angegeben den Garnkanal 13, 14, 15. In der in Fig. 3 gezeigten Einfädelstellung ist hingegen wenigstens eine-der beiden Ausnehmungen, im speziellen Fall die Ausnehmung im Teil 12, für das Einlegen von Multifilamentgarn freigelegt.The body of the preferred embodiment of the device according to the invention shown consists of the two
Die Halterung 23 enthält einen Blasmedium-Zufuhrkanal 24. In der Betriebsstellung des Teils 12, gemäss Fig. 1 und 2, ist die in diesem Teil 12 vorgesehene Blasmedium-Einlassöffnung 19 mit der Mündung des Blasmedium-Zufuhrkanals 24 ausgerichtet, so dass Blasmedium aus diesem Kanal 24 in die Zufuhrbohrungen 16, 17 und 18 gelangt und durch diese in den Garnkanal 13, 14, 15 ausgestossen wird. Wenn der Teil 12 durch einen nicht dargestellten Mechanismus aus der Betriebsstellung in die Einfädelstellung gemäss Fig. 3 verschoben wird, verschliesst der Teil 12 die Mündung des Blasmedium-Zufuhrkanals 24, und die Zufuhr von Blasmedium in den Einlass 19 wird unterbrochen.The
Ein teilweise orientiertes Polyester-Multifilamentgarn mit dem Titer 90f40 wurde einer konventionellen Strecktexturierung bei 500 m/min unterworfen. Das Produkt der Strecktexturierung war ein hochelastisches Polyestergarn mit dem Titer 50f40. Die Dicke dieses Garns in Abhängigkeit von der Garnspannung ist in Fig. 4 durch die Kurve A dargestellt. Nach der Abzugswalze der Strecktexturiermaschine wurde eine Behandlungsvorrichtung wie vorstehend anhand der Fig. 1 bis 3 beschrieben angeordnet. An dieser Stelle ist der Strecktexturierungsprozess beendet. Das hochelastische texturierte Garn wurde mit einer Ueberlieferung von 5% in den Garnkanal der Behandlungsvorrichtung eingeführt, und zwar ohne Benetzung. Der Behandlungsvorrichtung wurde Druckluft mit einem Druck von 3 bar zugeführt, und das behandelte Garn wurde unter einem Winkel von 90° zur Achse des Garnkanals 13, 14, 15 aus der handlungsvorrichtung abgeführt. Die Filamente des erhaltenen Garns waren auf der Länge des Garns kontinuierlich miteinander verflochten und bildeten keine abstehenden Schlingen. Die Dicke dieses Garns in Abhängigkeit von der Garnspannung ist in Fig. 4 durch die Kurve B dargestellt.A partially oriented polyester multifilament yarn with the titer 90f40 was subjected to conventional stretch texturing at 500 m / min. The product of the stretch texturing was a highly elastic polyester yarn with the titer 50f40. The thickness of this yarn as a function of the yarn tension is represented by curve A in FIG. 4. After the draw-off roller of the stretch texturing machine, a treatment device was arranged as described above with reference to FIGS. 1 to 3. At this point, the stretch texturing process has ended. The highly elastic textured yarn was introduced with a tradition of 5% into the yarn channel of the treatment device, without wetting. Compressed air at a pressure of 3 bar was fed to the treatment device, and the treated yarn was removed from the treatment device at an angle of 90 ° to the axis of the
Zum Vergleich wurde das als Produkt der Strecktexturierung erhaltene hochelastische Garn echt gedreht, mit 200 Drehungen pro Meter. Die Dicke des spinngedrehten Garns in Abhängigkeit von der Spannung ist in Fig. 4 durch die Kurve C dargestellt.For comparison, the highly elastic yarn obtained as the product of the stretch texturing was real twisted, with 200 twists per meter. The thickness of the spun yarn as a function of the tension is represented by curve C in FIG. 4.
Aus Fig. 4 ist zu ersehen, dass das in der erfindungsgemässen Vorrichtung behandelte Garn (Kurve B) im Vergleich zum zugeführten strecktexturierten Garn (Kurve A) hinsichtlich der Dicke eine Verbesserung zeigt, jedoch noch nicht so dick ist wie das gedrehte Garn (Kurve C). Eine visuelle Untersuchung der drei Garne ergibt ähnliche Resultate: Das in der erfindungsgemässen Vorrichtung wie beschrieben behandelte Garn ist kompakter als das zugeführte strecktexturierte Garn, jedoch weniger kompakt als das spinngedrehte Garn.It can be seen from FIG. 4 that the yarn treated in the device according to the invention (curve B) shows an improvement in thickness compared to the drawn textured yarn (curve A), but is not yet as thick as the twisted yarn (curve C ). A visual examination of the three yarns gives similar results: the yarn treated as described in the device according to the invention is more compact than the drawn-textured yarn supplied, but less compact than the spun-twisted yarn.
Die Weiterverarbeitbarkeit des in der erfindungsgemässen Vorrichtung behandelten Garns ist im Vergleich zum zugeführten strecktexturierten Garn stark verbessert, was sich z.B. beim Abwickeln mit hoher Geschwindigkeit und beim Schusseintrag beim Weben zeigt. Die Filamente in dem Garn sind in einer Weise miteinander verflochten, dass sich mit dem Garn Gewebe mit sehr gleichförmiger Struktur und gleichförmiger Anfärbbarkeit erzeugen lassen.The further processability of the yarn treated in the device according to the invention is greatly improved in comparison to the drawn textured yarn, which is e.g. when unwinding at high speed and when inserting weft during weaving. The filaments in the yarn are intertwined in such a way that the yarn can be used to produce fabrics with a very uniform structure and uniform dyeability.
