Description

Die Erfindung betrifft ein Verfahren zur Herstellung lufttexturierter Fäden aus zumindest einem Steherfaden und zumindest einem Effektfaden, bei dem zumindest der Steherfaden verstreckt wird, bevor er gemeinsam mit dem Effektfaden einer Texturiereinheit zugeführt wird und bei dem das texturierte, aus Steher- und Effektfaden bestehende Garn erhitzt wird.The invention relates to a method for producing air-textured Threads from at least one upright thread and at least an effect thread in which at least the upright thread is drawn before using a Texturing unit is supplied and in which the textured, yarn consisting of stand and effect thread is heated.

Derartige Verfahren machen sich den Effekt zunutze, daß während der nach der Texturiereinheit erfolgenden Erhitzung des texturierten Garns der vor der Texturierung verstreckte Steherfaden weniger stark schrumpft als der Effektfaden. Dies hat zur Folge, daß bei der Texturierung vom Effektfaden gebildete Schlingen während der genannten Erhitzung zusammengezogen werden, wodurch der Faden letztlich in wünschenswerter Weise eine relativ glatte Oberfläche erhält.Such methods take advantage of the effect that during the heating of the after the texturing unit textured yarn of the upright thread stretched before texturing shrinks less than the effect thread. This has the consequence that formed by the effect thread during texturing Loops contracted during said heating be, which ultimately makes the thread more desirable Way gets a relatively smooth surface.

Gemäß Stand der Technik wurde das beschriebene Verfahren bisher lediglich zur Herstellung von eine grobe Feinheit (tex) aufweisenden Fäden bzw. zur Herstellung von relativ dicken Fäden eingesetzt.According to the prior art, the method described has so far been used only for the production of a coarse fineness (tex) having threads or for the production of relatively thick Threads used.

Eine Aufgabe der Erfindung besteht darin, das Verfahren der eingangs genannten Art derart weiterzuentwickeln, daß auch dünne, sehr feine Fäden bei ausreichender Festigkeit derselben herstellbar sind.An object of the invention is the method of continue to develop in such a way that also thin, very fine threads with sufficient strength are producible.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß ein Steherfaden mit einer Feinheit zwischen 80 und 200 dtex und ein Effektfaden mit einer Feinheit zwischen 60 und 165 dtex verwendet wird, wobei der Effektfaden feiner ist als der Steherfaden. According to the invention this object is achieved in that a Upright thread with a fineness between 80 and 200 dtex and an effect thread with a fineness between 60 and 165 dtex is used, the effect thread is finer than the upright thread.

Durch den Einsatz von Steher- und Effektfäden mit den genannten Feinheiten lassen sich beispielsweise problemlos Fäden mit einer unter 200 dtex liegenden Feinheit bei einer Festigkeit von über 30 cN/tex erzeugen. Insbesondere lassen sich Feinheiten des Fadens von ungefähr 130 dtex erzielen, wobei gleichzeitig Festigkeiten zwischen 36 und 38 cN/tex sichergestellt werden können. Die Dehnung erfindungsgemäß hergestellter Fäden beträgt beispielsweise zwischen 11 und 12 %, d.h., der texturierte Faden kann in seiner Länge um 11 bis 12 % gedehnt werden, ohne zu reißen.By using upright and effect threads with the above Subtleties can easily be made into threads, for example with a fineness below 200 dtex with a firmness of over 30 cN / tex. In particular, Achieve yarn finenesses of approximately 130 dtex, whereby strengths between 36 and 38 cN / tex ensured at the same time can be. The elongation produced according to the invention Threads is, for example, between 11 and 12%, i.e. the length of the textured thread can be stretched by 11 to 12% be without tearing.

Durch das erfindungsgemäße Verfahren sind somit sehr feine Fäden herstellbar, die sowohl eine hohe Festigkeit als auch eine hohe Gleichmäßigkeit bei ebenfalls hoher Fehlerfreiheit aufweisen.The method according to the invention therefore makes them very fine Threads can be produced that are both high strength as well a high degree of uniformity with a high degree of freedom from errors exhibit.

Bevorzugt ist es, wenn ein Steherfaden mit einer Feinheit zwischen 140 und 160 dtex und/oder ein Effektfaden mit einer Feinheit zwischen 70 und 90 dtex verwendet wird. Steher- und/oder Effektfäden können jeweils zwischen 36 und 144 Filamente aufweisen.It is preferred if a stand thread with a fineness between 140 and 160 dtex and / or an effect thread with a Fineness between 70 and 90 dtex is used. Standing and / or Effect threads can have between 36 and 144 filaments each exhibit.

Um den Effekt des stärkeren Schrumpfes des Effektfadens verglichen mit dem Steherfaden nach der Texturiereinheit zu begünstigen, ist es von Vorteil, wenn der Steherfaden vor der Texturiereinheit um das 1,8- bis 2,6-fache, insbesondere um das 2- bis 2,4-fache verstreckt wird. Weiterhin ist es von Vorteil, wenn zusätzlich zum Steherfaden auch der Effektfaden vor der Texturiereinheit verstreckt wird, wobei die Verstreckung des Effektfadens vorzugsweise kleiner ist als die Verstreckung des Steherfadens. Der Effektfaden kann beispielsweise um das 1,5- bis 1,9-fache, insbesondere um das 1,6- bis 1,8-fache verstreckt werden. To compare the effect of the stronger shrinkage of the effect thread with the stand thread after the texturing unit, it is an advantage if the upright thread is in front of the Texturing unit by 1.8 to 2.6 times, in particular by stretched 2 to 2.4 times. Furthermore, it is from Advantage if, in addition to the upright thread, the effect thread is stretched in front of the texturing unit, the stretching of the effect thread is preferably smaller than the stretching of the thread. The effect thread can, for example by 1.5 to 1.9 times, in particular by 1.6 to Be stretched 1.8 times.

Vorteilhaft ist es weiterhin, wenn der Steher- und/oder der Effektfaden vor der Texturiereinheit erhitzt wird. Der Steherfaden kann dabei stärker erhitzt werden als der Effektfaden, wobei sich bezüglich der Erhitzung des Steherfadens Temperaturen zwischen 150° und 240°, insbesondere zwischen 160° und 220° anbieten.It is also advantageous if the upright and / or the Effect thread is heated before the texturing unit. The upright thread can be heated more than the effect thread, with temperatures regarding the heating of the standing thread between 150 ° and 240 °, in particular between 160 ° and offer 220 °.

Hinsichtlich der Erhitzung des Effektfadens sind beispielsweise Temperaturen zwischen 100°C und 200°C, insbesondere zwischen 140°C und 180°C sinnvoll.With regard to the heating of the effect thread, for example Temperatures between 100 ° C and 200 ° C, in particular between 140 ° C and 180 ° C makes sense.

Zur technischen Realisierung des erfindungsgemäßen Verfahrens kann der Steher- und/oder der Effektfaden vor der Texturiereinheit jeweils über zwei aufeinanderfolgende Galetten geführt werden. Die Verstreckung von Steher- und/oder Effektfaden kann dann beispielsweise durch unterschiedliche Antriebsgeschwindigkeiten zweier aufeinanderfolgender Galetten bewirkt werden, wobei die in Föderrichtung hintere Galette schneller läuft als die vordere Galette. Zusätzlich oder alternativ zur Verstreckung kann mittels der Galetten auch eine Erhitzung von Steher- und/oder Effektfaden bewirkt werden, indem mindestens eine der jeweils Steher- und/oder Effektfaden zugeordneten Galetten erwärmt wird. Hierbei können die Galetten auf die vorstehend bereits genannten Temperaturen erhitzt werden.For the technical implementation of the method according to the invention can the upright and / or the effect thread in front of the texturing unit each over two successive godets be performed. The drawing of upright and / or effect thread can then, for example, by different drive speeds two successive godets are effected, the rear godet in the direction of the conveyor runs faster than the front godet. Additionally or alternatively a stretching can also be carried out using the godets Heating of stand and / or effect thread can be effected, by at least one of the upright and / or effect threads assigned godets is heated. Here, the Godets to the temperatures already mentioned above be heated.

Um zu verhindern, daß zwischen den Galetten und Steher- und/oder Effektfaden Rutsch auftritt, können die Fäden jeweils zwischen 5 und 20 mal, insbesondere zwischen 6 und 10 mal schraubenförmig um eine Galette geschlungen werden, so daß die Reibungskräfte zwischen Galetten und Fäden ausreichend hoch sind. Durch die genannten Umschlingungen wird zudem im Falle der Beheizung der Galetten erreicht, daß die Fäden ausreichend lange mit der jeweiligen Galette in Kontakt sind, so daß genügend Wärme von der Galette auf die Fäden übertragen werden kann.To prevent that between the godets and standing and / or Effect thread slip occurs, the threads can each between 5 and 20 times, in particular between 6 and 10 times helically around a godet, so that the frictional forces between godets and threads are sufficient are high. The above-mentioned wraps also in the case of heating the godets that the threads sufficiently in contact with the respective godet are so that enough heat from the godet to the threads can be transferred.

Gemäß einer vorteilhaften Ausführungsform der Erfindung wird das texturierte Garn hinter der Texturiereinheit nachverstreckt. Diese Verstreckung kann beispielsweise um einen Faktor zwischen 0,95 und 1,1, insbesondere zwischen 1,01 und 1,05 erfolgen. Die Verstreckung erfolgt bevorzugt derart, daß derjenige Abstand des texturierten Garnes, welcher gerade erhitzt wird, auch gleichzeitig eine Nachverstreckung erfährt. So kann verhindert werden, daß sich das texturierte Garn während der Erhitzung insgesamt zu stark zusammenzieht. Konkret wird durch einen Nachverstreckungsfaktor größer 1 erreicht, daß die Steherfaden-Komponente des texturierten Garns während des Erhitzungsvorgangs gedehnt wird. Bei einem Nachverstreckungsfaktor kleiner 1 wird sichergestellt, daß die Steherfaden-Komponente maximal um den Nachverstreckungsfaktor schrumpfen kann.According to an advantageous embodiment of the invention the textured yarn is stretched behind the texturing unit. This stretching can, for example, by a factor between 0.95 and 1.1, in particular between 1.01 and 1.05. The stretching is preferably carried out in such a way that the distance of the textured yarn that is currently heating is also post-stretched at the same time. This can prevent that the textured yarn during the heating contracted too much overall. Concrete is achieved by a post-stretching factor greater than 1, that the main thread component of the textured yarn during of the heating process is stretched. With a post-stretch factor less than 1 ensures that the upright component maximum by the post-stretching factor can shrink.

Der Schrumpf der Steherfaden-Komponente des texturierten Garns ist somit durch die genannte Nachverstreckung begrenzt, und die durch den Effektfaden gebildeten Schlingen können sich durch die Erhitzung in gewünschter Weise verkleinern bzw. zusammenziehen.The shrinkage of the upright component of the textured Yarn is thus limited by the post-stretching mentioned, and the loops formed by the effect thread can decrease in size in the desired manner due to the heating or contract.

Die Erhitzung des texturierten Garns nach der Texturiereinheit wird bevorzugt derart vorgenommen, daß die Temperatur des texturierten Garns in dem genannten Bereich zwischen 200°C und 300°C, insbesondere zwischen 210°C und 260°C beträgt.The heating of the textured yarn after the texturing unit is preferably carried out such that the temperature of the textured yarn in the range between 200 ° C and 300 ° C, in particular between 210 ° C and 260 ° C.

Von Vorteil ist es, wenn auch das texturierte Garn über zwei aufeinanderfolgende Galetten geführt ist, wobei die Verstreckung des texturierten Garns in diesem Fall analog zur Verstreckung der Fäden vor der Texturiereinheit erfolgen kann. It is an advantage if the textured yarn over two successive godets is guided, the stretching of the textured yarn in this case analogous to the drawing the threads can be done in front of the texturing unit.

Auch bezüglich des texturierten Garns ist es aus den bereits genannten Gründen sinnvoll, wenn die Galetten vom texturierten Garns jeweils zwischen 5 und 20 mal, insbesondere zwischen 6 und 10 mal umschlungen werden.Regarding the textured yarn, it is already out of the mentioned reasons makes sense if the godets from the textured Yarns between 5 and 20 times, especially between To be wrapped 6 and 10 times.

Bei Durchführung des erfindungsgemäßen Verfahrens kann das texturierte Garn die Texturiereinheit mit einer Geschwindigkeit zwischen 300 m/min und 500 m/min, insbesondere mit 400 m/min verlassen.When carrying out the method according to the invention, this can textured yarn the texturing unit at a speed between 300 m / min and 500 m / min, especially at 400 leave m / min.

Um die Ausbildung von ausreichenden Schlingen des Effektfadens während des Texturiervorgangs zu ermöglichen ist es von Vorteil, wenn die Anliefergeschwindigkeit des Effektfadens höher als die Anliefergeschwindigkeit des Steherfadens ist, so daß im fertigen Faden letztlich die Länge des verarbeiteten Effektfadens größer ist als die Länge des verarbeiteten Steherfadens.For the formation of sufficient loops of the effect thread It is necessary to enable during the texturing process Advantage if the speed of delivery of the effect thread is higher than the delivery speed of the stand thread, so that in the finished thread ultimately the length of the processed Effect thread is greater than the length of the processed Standing thread.

Bevorzugt ist es, wenn sowohl Effektfaden als auch Steherfaden mit einer Geschwindigkeit angeliefert werden, welche über der Geschwindigkeit liegt, mit der das texturierte Garn die Texturiereinheit verläßt.It is preferred if both effect thread and upright thread are delivered at a speed which is above the speed at which the textured yarn Texturing unit leaves.

Die Anliefergeschwindigkeit des Steherfadens liegt bevorzugt zwischen 4 % und 8 %, insbesondere ungefähr 6 % über der Geschwindigkeit, mit der das texturierte Garn die Texturiereinheit verläßt.The delivery speed of the standing thread is preferred between 4% and 8%, especially about 6% above speed, with which the textured yarn the texturing unit leaves.

Die Anliefergeschwindigkeit des Effektfadens liegt bevorzugt zwischen 14 % und 20 %, insbesondere zwischen 16 % und 18 % über der Geschwindigkeit, mit der das texturierte Garn die Texturiereinheit verläßt. The speed of delivery of the effect thread is preferred between 14% and 20%, in particular between 16% and 18% over the speed at which the textured yarn Texturing unit leaves.

Die Texturiereinheit, die bevorzugt als Texturierdüse ausgebildet ist, kann beispielsweise mit einem Druck zwischen 6 und 14 bar betrieben werden.The texturing unit, which is preferably designed as a texturing nozzle with a pressure between 6 and operated at 14 bar.

Von Vorteil ist es, wenn der Steherfaden vor der Texturiereinheit mit Wasser beaufschlagt wird, wobei der Wasserdurchsatz beispielsweise zwischen 0,1 l/h und 1 l/h, insbesondere ungefähr 0,25 l/h betragen kann. Für die Wasserbeaufschlagung des Steherfadens kann beispielsweise normales Trinkwasser verwendet werden, welches zuvor ein Aktivkohlefilter passiert.It is advantageous if the upright thread in front of the texturing unit is charged with water, the water throughput for example between 0.1 l / h and 1 l / h, in particular can be approximately 0.25 l / h. For the application of water the thread can be normal, for example Drinking water can be used, which previously had an activated carbon filter happens.

Steher- und/oder Effektfaden können aus Polyester, Polyamid, Polyamid 6, Polyamid 6.6, Polyamid 4.6, Polyethylen und/oder Viskose bestehen.Standard and / or effect thread can be made of polyester, polyamide, Polyamide 6, polyamide 6.6, polyamide 4.6, polyethylene and / or Viscose exist.

Anstelle der Verwendung von lediglich einem Steher- und einem Effektfaden ist es alternativ möglich, der Texturiereinheit einen Steher- und zwei Effektfäden oder zwei Steher- und einen Effektfaden oder je zwei Steher- und Effektfäden zuzuführen.Instead of using only one standing and one It is alternatively possible to effect threads, the texturing unit one stand and two effect threads or two stand and one Feed effect thread or two upright and effect threads.

Um aus dem erfindungsgemäß hergestellten Faden letztlich einen Nähfaden zu erzeugen, kann das texturierte Garn insbesondere nach seiner Erhitzung verdreht werden. Die Verdrehung beträgt beispielsweise zwischen 150 und 600, insbesondere zwischen 300 und 500 Drehungen pro Meter.To ultimately one from the thread produced according to the invention The textured yarn can in particular produce sewing thread be twisted after heating. The twist is, for example, between 150 and 600, in particular between 300 and 500 turns per meter.
