The associated installation features a feed package (2) and a take-up package (3) as well as a yarn singeing burner (6). The wax applicator (5) is located between the feed package (2) and the burner (6).

Description

Die Erfindung betrifft ein Verfahren zur Behandlung von Garn gemäss dem Oberbegriff des Anspruchs 1 sowie eine Vorrichtung zur Durchführung des Verfahrens.The invention relates to a method for treating yarn according to the preamble of claim 1 and an apparatus for performing the method.

Es ist schon seit langem bekannt, die Haarigkeit von Garnen, die bei bestimmten Anwendungen störend ist, indem sie z. B. eine gewisse Flauschigkeit des Gewebes bewirkt, durch Sengen zu reduzieren und dadurch vor allem für die Herstellung glatter, glänzender Gewebe geeignete Garne herzustellen. Das Sengen wird auf eigens dafür vorgesehenen Sengmaschinen ausgeführt, auf welchen das Garn von einer Vorlagespule auf eine Aufwickelspule umgespult und dabei durch einen Garnsengbrenner gezogen wird. Derartige Sengmaschinen sind z. B. in DE-C-3 031 797 und in Dipl.-Ing. J. Schneider: Vorbereitungsmaschinen für die Weberei, Springer Verlag 1955, S. 59 - 65 beschrieben.It has been known for a long time, the hairiness of yarns, which is annoying in certain applications, e.g. B. causes a certain fluffiness of the fabric to reduce by singeing and thereby especially suitable yarns for the production of smooth, shiny fabrics. The singeing is carried out on specially provided singeing machines, on which the yarn is rewound from a supply spool to a take-up spool and pulled through a yarn singe burner. Such scorching machines are e.g. B. in DE-C-3 031 797 and in Dipl.-Ing. J. Schneider: Preparation machines for weaving, Springer Verlag 1955, pp. 59-65.

Ausserdem ist es seit langem bekannt, den Reibwert von Garnen durch Aufbringen von Wachs, z. B. von Trockenparaffin, zu beeinflussen, vor allem, ihn im Hinblick auf eine Verwendung derselben in Wirk- oder Strickmaschinen herabzusetzen. Im Prosekt "Präparations-Systeme" der SSM Schärer Schweiter Mettler AG sind mehrere Typen von Aufbringvorrichtungen beschrieben und dargestellt.In addition, it has long been known to reduce the coefficient of friction of yarns by applying wax, e.g. B. of dry paraffin, especially to reduce it with a view to using the same in knitting or knitting machines. Several types of application devices are described and illustrated in the "Preparation Systems" prosect from SSM Schärer Schweiter Mettler AG.

Für bestimmte Anwendungen müssen Garne sowohl gesengt als auch durch Aufbringen von Wachs präpariert werden. Wegen der Hitzeempfindlichkeit des Wachses war man immer davon ausgegangen, dass ein Sengen von bereits gewachstem Garn zum Abdampfen oder zu untragbaren chemischen Veränderungen des Wachses führen müsse, auch Zerstörung oder mindestens Beschädigung des Garns bewirken dürfte, weshalb das Garn unbedingt zuerst gesengt und dann gewachst werden müsse. Da Garn beim Sengen zu heiss wird, als dass es in einem einzigen Umspulvorgang nacheinander gesengt und gewachst werden könnte, sind bei dieser Reihenfolge stets zwei Umspulvorgänge erforderlich, was natürlich hohen Zeit- und auch apparativen Aufwand für die kombinierte Behandlung bedeutet.For certain applications, yarns have to be scorched as well as prepared by applying wax. Because of the heat sensitivity of the wax, it had always been assumed that singeing wax that had already been waxed would lead to evaporation or intolerable chemical changes to the wax, and that the thread would also be destroyed or at least damaged, which is why the thread must be scorched first and then waxed. Since yarn becomes too hot during singeing to be seared and waxed one after the other in a single rewinding process, two rewinding processes are always required in this sequence, which of course means a lot of time and equipment for the combined treatment.

Ueberraschenderweise hat sich jedoch herausgestellt, dass beim Sengen von gewachstem Garn nicht nur keine Minderung seiner Qualität oder gar Zerstörung oder Beschädigung desselben auftritt, sondern in vielen Fällen sogar Garn mit besonders tiefen Reib- und Haarigkeitswerten entsteht, welche unter den Werten liegen, die bei gleichem Ausgangsmaterial durch Sengen und anschliessendes Aufbringen von Wachs erzielt werden.Surprisingly, however, it has been found that when waxed yarn is singed, not only does its quality not deteriorate, nor does it destroy or damage it, but in many cases even yarn with particularly low friction and hairiness values is produced, which are below the values of the same Starting material can be obtained by singeing and then applying wax.

Die erfindungsgemässe Behandlung von Garn führt in völlig unerwarteter Weise zu Resultaten, die günstiger sind als die mit dem bisher üblichen Verfahren erzielten. Darüberhinaus erlaubt sie eine wesentliche Vereinfachung und Beschleunigung des Verfahrens, da Aufbringen von Wachs und anschliessendes Sengen ohne weiteres in einem Arbeitsgang ausgeführt werden können.The treatment of yarn according to the invention leads in completely unexpected ways to results which are more favorable than those achieved with the previously customary method. In addition, it allows a significant simplification and acceleration of the process, since the application of wax and subsequent singeing can easily be carried out in one operation.

Die Erfindung schafft ausserdem eine zur Behandlung von Garn durch Aufbringen von Wachs und anschliessendes Sengen während eines einzigen Umspulvorgangs geeignete Vorrichtung.The invention also provides a device suitable for treating yarn by applying wax and then singeing during a single rewinding operation.

Im folgenden wird die Erfindung anhand einer Figur dargestellt, die in Seitenansicht ein Beispiel einer erfindungsgemässen Vorrichtung zur Durchführung des erfindungsgemässen Verfahrens zeigt.The invention is illustrated below with the aid of a figure which shows an example of a device according to the invention for carrying out the method according to the invention in side view.

Die Vorrichtung weist am Fuss eines Gehäuses 1 eine Vorlagespule 2 auf und oben eine Auflaufspule 3, welche von einer Nutentrommel 4, die gleichzeitig als Fadenverlegevorrichtung dient, angetrieben wird. Oberhalb der Vorlagespule 2 ist ein Paraffineur 5 bekannter Bauart, bei welchem das Garn über die Stirnfläche eines rotierenden Zylinders aus Trockenparaffin gezogen wird, angeordnet, darüber ein Garnsengbrenner 6, vorzugsweise ein Gasbrenner ebenfalls bekannter Ausführung. Statt des Paraffineurs 5 könnte auch eine bekannte Aufbringvorrichtung für Heiss- oder Kaltwachs eingesetzt werden. Zwischen dem Garnsengbrenner 6 und der Nutentrommel 4 ist ein Fadenwächter 7 zur Feststellung von Fadenbrüchen angebracht. Zur Regelung der Fadenspannung und damit des Paraffinauftrags am Paraffineur 5 sowie der Dichte der Auflaufspule 3 ist vor und hinter dem Paraffineur 5 je eine Fadenbremse 9a bzw. 9b angeordnet. Schliesslich ist die Vorrichtung mit einer oberhalb des Garnsengbrenners 6 angebrachten Absaugeinrichtung versehen (nicht dargestellt), die beim Sengen entstandene Verunreinigungen vom Garn absaugt.The device has at the foot of a housing 1 a supply spool 2 and above a package 3, which by a groove drum 4, which at the same time Thread laying device is used, driven. A paraffin 5 of a known type, in which the yarn is drawn over the end face of a rotating cylinder made of dry paraffin, is arranged above the supply spool 2, and a yarn burner 6, preferably a gas burner likewise of a known design, is arranged above it. Instead of the paraffin 5, a known application device for hot or cold wax could also be used. Between the yarn singe burner 6 and the grooved drum 4, a thread monitor 7 is attached for the detection of thread breaks. To regulate the thread tension and thus the paraffin application on the paraffin 5 and the density of the package 3, a thread brake 9a and 9b is arranged in front of and behind the paraffin 5. Finally, the device is provided with a suction device (not shown), which is attached above the yarn singe burner 6 and which sucks off impurities formed during the singeing process from the yarn.

Beim Betrieb der Vorrichtung wird ein Faden 8 von der Vorlagespule 2 abgezogen und nacheinander durch die Fadenbremse 9a, den Paraffineur 5, die Fadenbremse 9b und den Garnsengbrenner 6 sowie über den Fadenwächter 7 und die Nutentrommel 4 gezogen und auf der Auflaufspule 3 aufgewickelt. Der Faden 8 wird also bei einem einzigen Umspulvorgang zuerst paraffiniert und dann gesengt. Bei Fadenbruch wird die Nutentrommel 4 angehalten.When the device is operating, a thread 8 is drawn off the supply spool 2 and successively pulled through the thread brake 9a, the paraffin 5, the thread brake 9b and the yarn burner 6 as well as over the thread monitor 7 and the grooved drum 4 and wound on the package 3. The thread 8 is thus first paraffined in a single rewinding operation and then scorched. If the thread breaks, the grooved drum 4 is stopped.

Vergleichsversuche wurden z. B. mit Baumwollgarnen der Feinheit Nm 36 durchgeführt und haben dort zu folgenden Ergebnissen geführt: durchschnittlicher Reibwert: unbehandelt: 0,2 nur gesengt: 0,18 nur paraffiniert: 0,145 erst gesengt, dann paraffiniert: 0,105 erst paraffiniert, dann gesengt: 0,1 Haarigkeit*: unbehandelt: 9,55 nur paraffiniert: 9,53 nur gesengt: 5,13 erst gesengt, dann paraffiniert: 5,74 erst paraffiniert, dann gesengt: 5,06 *) gemessen auf "USTER-TESTER 3" der Firma Zellweger Uster Comparative tests were carried out e.g. B. carried out with cotton yarn of fineness Nm 36 and have led to the following results: average coefficient of friction: untreated: 0.2 just scorched: 0.18 only paraffinated: 0.145 first scorched, then paraffinated: 0.105 first paraffinated, then scorched: 0.1 Hairiness *: untreated: 9.55 only paraffinated: 9.53 just scorched: 5.13 first scorched, then paraffinated: 5.74 first paraffinated, then scorched: 5.06 *) measured on "USTER-TESTER 3" from Zellweger Uster
