Description
Die vorliegende Erfindung betrifft eine Vorrichtung zum Texturieren von Garn, bestehend aus einer Kontaktröhre, der koaxial ein Einlaßrohr für ein Hochtemperaturfiuid vorgeschaltet ist und einem Garnauslaß, welcher seitlich am Eingang der Kontaktröhre mündet. The present invention relates to a device for texturing yarn, consisting of a contact tube, which is coaxially preceded by an inlet tube for a high temperature fluid and a yarn outlet which opens laterally at the entrance of the contact tube.
Texturierungsdüsen der genannten Art, so z. B. die in US-PS 34 09 956 erwähnte Düse, werden gegenwärtig dazu verwendet, eine kontinuierliche, fortlaufende Länge Kunststoff- bzw. Nylongarn zu texturieren, so daß es zu Teppichen getuftet oder verwebt werden kann. Die bekannten Düsen verwenden überhitzten Dampf, dessen Temperatur über dem Schmelzpunkt des Garnes liegt. Wenn das Garn in Bewegung ist, reicht die Wärmeübertragung auf das Garn nicht aus, um es zu schmelzen. Es können jedoch aus den verschiedensten Gründen Unterbrechungen im Verfahren eintreten. |cde Verführensunterbrechung, welche ein Anhalten des Garnes in der Düse bedingt, kann ein Schmelzen des Garnes in der Düse verursachen. Die Düse muß dann entfernt und gereinigt werden, um das geschmolzene Polymer mit einem Lösungsmittel oder auf andere Art zu entfernen. Das geschmolzene Garn verursacht den längeren Ausfall eines Abschnittes des kontinuierlichen Garntexuiricrungsverfahrens und zusätzlich Kosten für die Reinigung der Düse.Texturing nozzles of the type mentioned, so for. B. the nozzle mentioned in US-PS 34 09 956 are present used to texturize a continuous length of synthetic or nylon yarn, see above that it can be tufted or woven into carpets. The known nozzles use superheated Steam at a temperature above the melting point of the yarn. If the yarn is in motion, that's enough Heat transfer to the yarn does not cause it to melt. However, it can come from the most diverse Reasons for interruptions in the proceedings. | cde seduction break which a halt of the yarn in the nozzle, the Cause twine in the nozzle. The nozzle must then be removed and cleaned to remove the melted Remove polymer with a solvent or other means. The melted yarn causes that prolonged failure of a section of the continuous yarn threading process and additional costs for cleaning the nozzle.
Der Erfindung liegt die Aufgabe zugrunde, das Schmelzen des Garns in der Düse /u verhindern, wenn aufgrund einer Verfahrensunterbrechung das Garn in der Düse angehalten wird. The invention is based on the object of preventing the yarn from melting in the nozzle / u if the yarn is stopped in the nozzle due to a process interruption.
Diese Aufgabe wird durch die Vorrichtung gemäß Anspruch 1 gelöst This object is achieved by the device according to claim 1
Die erfindungsgemäße Vorrichtung liefert einen Strahl von Hochdruckfluid, z. B. Luft, um das Hochtemperaturfiuid, z. B. Dampf, aus der Texturierungsdüsen- vorrichtung hinauszuführen. Die Vorrichtung sieht vor, daß das Anhalten des Garnes mit einem SensorThe device of the invention provides a jet of high pressure fluid, e.g. B. air to the Hoch Temperaturfiuid, z. B. steam, out of the texturing nozzle device. The device provides that the stopping of the yarn with a sensor
to abgetastet und ein Ventil in einer Hochdruckfluidleitung betätigt wird, welche mit einer dem Garneinlaß in der Texturierungsdüsenvorrichtung gegenüberliegenden Öffnung in Verbindung steht, und daß das Hochtemperaturfiuid, das quer über den Garneinlaß strömt, mit dem Strahl Hochdruckfluid durch den Garneinlaß aus der Texturierungsdüsenvorrjchtung abgeleitet wird. Ein Teil des Hochtemperaturfluids kann weiter quer über den Gamschlutz strömen, es wird jedoch durch das Hochdruckfluid verdünnt und abgekühlt. Dadurchto is scanned and a valve in a high pressure fluid line is actuated which is in communication with an opening opposite the yarn inlet in the texturing nozzle device, and that the high temperature fluid which flows across the yarn inlet is discharged with the jet of high pressure fluid through the yarn inlet from the texturing nozzle device. Some of the high-temperature fluid can continue to flow across the gauntlet, but it is diluted and cooled by the high-pressure fluid. Through this
Μ werden alle Elemente in der Texturierungsdüsenvorrichtung stromabwärts vom Garneinlaß, wie in der obenangeführten US-PS 34 09 956 gezeigt, bei Anhalten des Garnes nicht langer von dem Hochtemperaturfiuid erhitzt. Dadurch wird das Schmelzen des in der Hochtemperatur-Texturierungsdüse festsitzenden Garnesvermieden. Μ will all elements in the texturing nozzle device downstream of the yarn inlet, as shown in the above-referenced US Pat. No. 3,4.09,956, when stopped of the yarn is no longer heated by the high temperature fluid. This will cause the melting of the in the High-temperature texturing nozzle avoids stuck yarn.
Bevorzugte Sensoren sind ein Fühlerarm oder eine Rolle bzw. Walze, welche so angebracht sind, daß sie die kontinuierlich fortlaufende Garnlänge berühren.Preferred sensors are that they touch a feeler or a roller, which are mounted so that continuously continuous length of yarn.
