Abstract
Description
Die Erfindung betrifft ein Verfahren zum Herstellen eines elastischen Zwirns, bei dem ein Elastomerfaden von etwa 140 bis 200 den mit zwei Garnen, deren Stärke jeweils etwa nur 1/10 des Elastomerfadens beträgt, haftend verzwirnt wird, wobei als Garne vorzugsweise im Rotorverfahren hergestellte OE-Garne aus Polyvinylchlorid, Polyvinylzwanid, Polyacrylnitril- und/oder wollfdäen verwendet und die Garne vor dem Verzwirnen zum Auflockern bei einem Unterdruck zwischen etwa 0,1 und 0,2 bar in Heißdampf von etwa 70° C bis zu 10 Minuten an ihrer Oberfläche angequollen werden sowie dem Elastomerfaden bei der Verzwirnung gegenüber den Garnen eine Vorspannung gegeben wird.The invention relates to a method for producing an elastic thread, in which an elastomer thread of approximately 140 to 200 is adhesively twisted with two yarns, the strength of each of which is only about 1/10 of the elastomer thread, the yarns preferably being produced by the rotor method. yarn of polyvinyl chloride, Polyvinylzwanid, polyacrylonitrile and / or wollfdäen used and the yarns prior to twisting for loosening at a negative pressure between about 0,1 and 0,2 bar in hot steam of about 70 ° C up to 10 minutes at its surface on g be equollen as well as the elastomer thread is given a pretension when twisting against the yarns.
Elastische Zwirne bestehen üblicherweise aus einem Elastomerfaden und zwei Garnen aus Natur- oder Synthetilfäden, welche diesen meist ungefärbten Elastomerfaden verbergen. Bisher war es schwierig, aus preiswerten OE-Garnen und einem Elastomerfaden elastische Zwirne herzustellen. OE-Garne werden nämlich im Rotorverfahren hergestellt, sind sehr hart und weisen einen etwa kreisrunden Querschnitt auf. Derartige runde Garne neigen nicht dazu, an der Oberfläche des Elastomerfadens zu haften und derart beim Auseinancerrecken und Zusammenziehen des Elastomerfadens an einem einmal einge-nommenen Platz zu bleiben, sondern gleiten auf dem Elastomerfaden hin und her, wodurch nach einiger Zeit das äußerst unerwünschte "Grinsen" des nicht eingefärbten, meist weißlichen Elastomerfadens auftritt. Aus diesem Grunde wurde in der US-PS 21 46 966 vorgeschlagen, derartige Garne, die nicht selbsttätig am Elastomerfaden haften, mit Hilfe eines geeigneten, beispielsweise wärmeaktivierbaren Klebstoffes am Elastomerfaden festzukleben. Dabei wird der Elastomerfaden vor dem Verzwirnen mit einem wärmeaktivierbaren Klebstoff versehen, verzwirnt und nach dem Zwirnvorgang durch eine Wärmebehandlung aktiviert, wodurch die Garne mit dem Elastomerfaden fest verklebt werden. Dieses Verfahren benötigt also stets mit Klebstoff getränkte Garne, welche unter Umständen unliebsame Eigenschaften haben können - beispielsweise kann der Klebstoff auf Dauer Farben verändern, ist teuer, ruft unter Umständen Allergien hervor und reagiert, insbesondere bei erhöhten Temperaturen, unerwünscht mit freien Valenzen der Chemiefasern.Elastic threads usually consist of an elastomer thread and two yarns made of natural or synthetic threads, which hide this mostly undyed elastomer thread. So far, it has been difficult to produce elastic threads from inexpensive OE yarns and an elastomer thread. OE yarns are made using the rotor process, are very hard and have an approximately circular cross-section. Such round yarns do not tend to adhere to the surface of the elastomeric thread and g to remain so during Auseinancerrecken and contraction of the elastomer yarn at a once an e-taken place but slide on the elastomer thread back and forth, which after some time the extremely undesirable "Grin" of the non-colored, mostly whitish elastomer thread occurs. For this reason, it was proposed in US Pat. No. 2,146,966 to glue such yarns that do not automatically adhere to the elastomer thread to the elastomer thread using a suitable, for example heat-activatable adhesive. Before the twisting, the elastomer thread is provided with a heat-activatable adhesive, twisted and activated after the twisting process by a heat treatment, as a result of which the yarns are firmly bonded to the elastomer thread. This process therefore always requires yarns impregnated with glue, which may have undesirable properties - for example, the glue can change colors in the long run, is expensive, may cause allergies and, particularly at elevated temperatures, undesirably reacts with free valences of the synthetic fibers.
In der DE-OS 28 11 329 ist daher ein verbessteres Verfahren, der gattungsgemäßen Art vorgesehen worden, bei dem durch Verwendung durch Dämpfen aufcerauhter und angequollener Garne, die derart leichter am Elestomerfaden haften, jedenfalls ein guter Verbund mit dem Elastomerfaden erreicht werden kann, ohne daß ein Hinsatz teurer und sich nachteilig auf die Produktgualität auswirkender Klebstoffe notwendig wäre. Dabei wird der Elastomerfaden bevorzugt unter einer etwa 3,5-fachen Vorspannung verzwirnt.In DE-OS 28 11 329, therefore, a better method of the generic type has been provided, in which a good bond with the elastomer thread can in any case be achieved by using roughened and swollen yarns which adhere more easily to the elastomer thread that it would be necessary to add expensive and adversely affecting adhesives. The elastomer thread is preferably twisted under approximately 3.5 times the pretension.
Es hat sich nun herausgestellt, daß bei der Herstellung dieser Zwirne beim Anlaufen und Anhalten der Zwirnvorrichtung häufig Fadenrisse auftreten, insbesondere dann, wenn eine Maschine kurzzeitig abgestellt werden muß, ohne daß beispielsweise Garnrollen oder dergleichen ausgetauscht werden.It has now been found that thread breaks often occur in the manufacture of these twists when the twisting device starts up and stops, especially when a machine has to be stopped for a short time without, for example, spools of thread or the like being replaced.
Der Erfindung liegt daher die Aufgabe zugrunde, dieses Abreißen von Fäden während der Anlaufphase der Zwirnvorrichtung zu vermeriden, wobei die Vorteile des Verfahrens nach der DE-OS 28 11 329 beibehalten und eine erhöhte Produktivität mit geringeren Ausfallzeiten ermöglicht werden sollen.The invention is therefore based on the object of avoiding this tearing of threads during the start-up phase of the twisting device, the advantages of the method according to DE-OS 28 11 329 being retained and increased productivity with less downtime being made possible.
Diese Aufgabe wird bei einem Verfahren der eingangs ge-nannten Art erfindungsgemäß dadurch gelöst, daß die Spannung des Elastomerfadens bei Ingangsetzen der Zwirnvorrichtung in etwa gleich der Spannung der Garne gehalten und erst nach einem vorherbestimmten Zeitraum nach Ingangsetzen der Zwirnvorrichtung dem Elastomerfaden gegenüber den Garnen eine zwischen etwa 2- bis etwa 5-fache Vorspannung gegeben wird.This object is achieved with a method of the type mentioned g-e according to the invention achieved in that the tension of the elastomeric yarn during starting the twisting device held equal to the tension of the yarns in approximately and only after a predetermined period of time after Starting the twisting device between about 2 and about 5 times the pre-tension is given to the elastomer thread.
Die erfindungsgemäß vorgeschlagene Vorrichtung zur Durchführung dieses Verfahrens zeichnet sich dadurch aus, daß zwei Getriebe mit unterschiedlichen Übersetzungen zur Übertragung des Drehmoments einer Antriebswelle auf Liefer-und Druckzylinder einer Zwirnvorrichtung vorgesehen sind, wobei das eine Getriebe mit einer Übersetzung, die in etwa gleiche Liefergeschwindigkeit für Garn- und Elastomerfäden ergibt, von einer Kupplung an die Antriebswelle bei Einschalten der Zwirnvorrichtung an- und nach einem vorherbestimmten Zeitraum abgekuppelt und das andere Getriebe, das eine etwa 2- bis 5-fach kleinere Liefergeschwindigkeit des Elastomerfadens gegenüber den Garnen bewirkt, gleichzeitig eingekuppelt wird.The device proposed according to the invention for carrying out this method is characterized in that two gears with different ratios are provided for transmitting the torque of a drive shaft to the delivery and pressure cylinders of a twisting device, the one gear with a ratio that has approximately the same delivery speed for yarn - And elastomeric threads results from a clutch on the drive shaft when switching on the twisting device and uncoupled after a predetermined period of time and the other gear, which causes an approximately 2 to 5 times lower delivery speed of the elastomeric thread compared to the yarns, is simultaneously coupled.
Dadurch, daß die Vorspanung erst nach Anlaufen der Vorrichtung aufgebaut wird, kann erreicht werden, daß der Elastomerfaden nicht in der Anlaufphase überdehnt wird oder die Garnfäden plötzlich so hoch beim Anfahren belastet, daß sie reißen.Because the pretensioning is built up only after the device has started up, it can be achieved that the elastomer thread is not overstretched in the start-up phase or the yarn threads are suddenly loaded so high when starting that they tear.
Weitere Merkmale und Vorteile der Erfindung ergeben sich aus den Ansprüchen und aus der nachfolgenden Beschreibung, in der ein Ausführungsbeispiel an Hand der aus einer einzigen Figur bestehenden Zeichnung, welche eine schematische Darstellung einer Vorrichtung zur Durchführung des erfindungsgemaßen Verfahrens zeigt, beschrieben ist.Further features and advantages of the invention result from the claims and from the following description, in which an exemplary embodiment is described with reference to the drawing consisting of a single figure, which shows a schematic representation of an apparatus for carrying out the method according to the invention.
Bei dem erfindungsgemäßen Verfahren wird ein elastischer Zwirn 11 aus einem Elastemerfaden 10 und zwei Garnen, bevorzugt OE-Garnen, obwohl sich die Erfindung allgemein auf das Herstellen von Elastomerfaden richtet, hergestellt. Wie im Hauptpatent beschrieben und in der einzigen Figur dargestellt ist, werden die drei Fäden über eine Umlenkrolle 24 für den Elastomerfaden bzw. Führungsrollen 26, 27, 28 im wesentlichen parallel ausgerichtet in einem Zwirnring 21 verzeirnt Dabei werden die nicht-elastischen Garne 13 und 14 von ihren Garnrollen 16, 17 durch das Zusammenwirken eines Druckzvlinders 19, der bedarfsweise auf dem Ljeferzylinder 18 aufliegt, abgezogen. Die Fördergeschwindigkeit der Garne wird dabei. durch die Drehgeschwindigkeit des Lieferzylinders 18 bestimmt. Der Elsstomerfaden 10 wird von seiner Vorratsrolle 22 mit Hilfe eines Lieferzylincers 23 abgezogen, wobei die Vorspannung des Elzstonerfadens von der Drehgeschwindigkeit des Lieferzylinders 23 abhängt. Der Lieferzylinder 23 sowie der Lieferzylinder 18 werden durch eine gemeinsame Antriebswelle 38 angetrieben, wobei die jeweiligen Umdrehungsgeschwindigkeiten über Übersetzungsgetriebe 34, 36 geregelt werden.In the method according to the invention, an elastic one Thread 11 is made from an
Dabei sind in der Figur zwei verschiedene Übersetzungen dargestellt. Die erste Übersetzung, die durch das Getriebe 34 erfolgt, welches bei der dargestellten Betriebsweise gerade eingekuppelt ist und daher wirksam ist, führt zu einer Liefergeschwindigkeit von Elastomerfaden und Garnen von etwa 1 : 1. Der Elastomerfaden ist also gegenüber den Garnen nicht vorgespannt. Das andere, in der Zeichnung als nicht-eingekuppelt dargestellte Getriebe 36 führt zu einer etwa 2- bis etwa 5-fachen Vorspannung des Elhstomerfadens, indem der Lieferzylinder 23 sich gegenüber dem Lieferzylinder 18 langsainer dreht.Two different translations are shown in the figure. The first translation, which takes place through the
Das Ingangsetzen der Vorrichtung, die zur Durchführung des erfindungsgemäßen Verfahrens verwendet wird, verläuft folgendermaßen:The device which is used to carry out the method according to the invention is started up as follows:
Zunächst wird durch das Anschalten die erste Kupplung 30 beaufschlagt, welche eingekuppelt - wie in der Figur gezeigt -, wodurch das Drehmoment der Antriebswelle 38 bei einer etwa 1 : 1-fachen Übersetzung zu etwa gleicher Liefergeschwindigkeit für elastisches Garn und OE-Garn führt. Kach einer vorbestimmten Zeit wird, beispielsweise durch einen elektrischen Zeitkreis oder ähnliche, dem Fachmann wohlbekannte Einrichtungen, die zweite Kupplung 32 beaufschlagt und gleichzeitig die Kunplung 30 getrennt, so daß das Drehmoment der Antriebswelle 38 nunmehr über das Getriebe 36 wirkt. Bei diesem Antrieb wird dem Elastomerfaden eine etwa 2- bis 5-fache, bevorzugt 3,5-fache Vorspannung gegenüber den unelastischen Garnfäden gegeben.First of all, the
Selbstverständlich liegt es im Bereich des Erfindungs-gedankens, statt einer Elektrokupplung mechanische Kupplungen vorzusehen, welche auch beliebig manuell geschaltet sein können. Es ist jedoch bevorzugt, die Kupplungen derart zu kuppeln, daß lediglich eine Kupplung eingerastet sein kann und wirksam ist.Of course, it is within the Erfindun g s-thought, instead of providing an electrical coupling mechanical couplings, which can also be connected arbitrarily manually. However, it is preferred to couple the clutches such that only one clutch can be engaged and is effective.
Die in der vorstehenden Beschreibung, in der Zeichnung sowie in den Ansprüchen offenbarten Merkmale der Erfindung können sowohl einzeln als auch in beliebiger Kombination für die Verwirklichung der Erfindung in ihren verschiedenen Ausführungsformen wesentlich sein.The features of the invention disclosed in the above description, in the drawing and in the claims can be essential both individually and in any combination for realizing the invention in its various embodiments.
