Abstract

Die Erfindung betrifft ein Verfahren zum Betrieb einer Luftspinnmaschine, wobei die Luftspinnmaschine wenigstens eine Spinnstelle mit einer Spinndüse (2) zur Herstellung eines Garns (6) aufweist, wobei der Spinndüse (2) während des Betriebs der Spinnstelle ein Faserverband (3) über einen Einlass (4) und in einer vorgegebenen Transportrichtung (T) zugeführt wird, wobei der Faserverband (3) innerhalb einer Wirbelkammer (5) der Spinndüse (2) mit Hilfe einer Wirbelluftströmung eine Drehung erhält, so dass aus dem Faserverband (3) ein Garn (6) gebildet wird, das die Spinndüse (2) schließlich über einen Auslass (7) verlässt, wobei das den Auslass (7) verlassende Garn (6) mit Hilfe wenigstens einer Sensorik (11) hinsichtlich definierter Garnfehler (26) überwacht wird, und wobei die Herstellung des Garns (6) bei einer Detektion eines entsprechenden Garnfehlers (26) unterbrochen wird. Erfindungsgemäß wird vorgeschlagen, dass zwischen der Detektion des genannten Garnfehlers (26) und der Unterbrechung der Garnherstellung zumindest gelegentlich ein Reinigungsvorgang durchgeführt wird, während dessen der Spinnstelle ein Additiv (9) zugeführt und auf den Faserverband (3) und/oder das aus dem Faserverband (3) hergestellte Garn (6) und/oder auf Teile der Spinndüse (2) aufgebracht wird. Darüber hinaus wird eine Luftspinnmaschine zur Durchführung des Verfahrens vorgeschlagen.

The invention relates to a method for operating an air-jet spinning machine, wherein the air-spinning machine has at least one spinning station with a spinneret (2) for producing a yarn (6), wherein the spinneret (2) during operation of the spinning station a fiber strand (3) via an inlet (4) and in a predetermined transport direction (T) is fed, wherein the fiber structure (3) within a vortex chamber (5) of the spinneret (2) by means of a vortex air flow receives a rotation, so that from the fiber structure (3) a yarn ( 6), which finally leaves the spinneret (2) via an outlet (7), wherein the yarn (6) leaving the outlet (7) is monitored for defined yarn defects (26) by means of at least one sensor (11); wherein the production of the yarn (6) is interrupted upon detection of a corresponding yarn defect (26). According to the invention, it is proposed that between the detection of said yarn defect (26) and the interruption of the yarn production at least occasionally a cleaning process is carried out, during which the spinning station an additive (9) and fed to the fiber structure (3) and / or from the fiber structure (3) produced yarn (6) and / or on parts of the spinneret (2) is applied. In addition, an air-spinning machine is proposed for carrying out the method.
