Die Erfindung liegt auf dem Gebiet der Luftblastexturierung. Um die gewünschten Effekte bei der Luftblastexturierung zu erreichen, werden heute sehr hohe Luftdrücke im Bereich von 10 bar und mehr benötigt, was aber für viele Textilbetriebe, die mit einer in der Regel auf Drücke um etwa 6 bar beschränkten Druckluftversorgung ausgerüstet sind, zu hoch ist. Wenn ein solcher Betrieb in den Bereich Luftblastexturierung investieren wollte, müsste er auch in eine neue Druckluftversorgung mit höheren Drücken investieren, was viele Betriebe abschreckt.The invention is in the field of airblast texturing. To get the desired effects To achieve airblast texturing today are very high air pressures in the range of 10 bar and more needed, but for many textile companies that are usually at pressures To about 6 bar limited compressed air supply are equipped, is too high. When a would like to invest in the field of airblast texturing, he would also have to invest in one invest new compressed air supply with higher pressures, which deters many companies.

In the following the invention will be explained in more detail with reference to an embodiment and the drawings; showing:
Fig. 1
an axial section through a texturing; and
Fig. 2
a schematic sectional view of an inventive yarn treatment device.

Die in Fig. 1 dargestellte Texturierdüse 1 besteht in bekannter Weise aus einem zylindrischen Düsenkörper 2 mit einem den Düsenkopf bildenden Flansch 3, einem in der Längsachse der Texturierdüse 1 geführten Garnkanal 4, der von dem zu behandelnden Garn in Richtung des Pfeiles A durchlaufen wird, und aus mehreren, vorzugsweise zwei oder drei, unter einem spitzen Winkel α in den Garnkanal 4 einmündenden Druckluftkanälen 5. Der Garnkanal 4 weist einen konisch zusammenlaufenden Einlaufteil 6, einen zylindrischen Mittelteil 7 und einen sich konisch öffnenden Auslaufteil 8 auf. Die Druckluftkanäle 5 münden in den zylindrischen Mittelteil 7 des Garnkanals, der unmittelbar nach der Einmündung der Druckluftkanäle 5 in den konischen Auslaufteil 8 übergeht. Die Druckluftkanäle 5 werden über eine Druckluftzuleitung 9 (Fig. 2) mit hochkomprimierter Luft gespeist, was durch einen Pfeil P symbolisiert ist, und blasen diese in den Garnkanal 4 ein, wobei sich im konischen Auslaufteil 8 des Garnkanals 4 eine Überschallströmung einstellt. Die dabei entstehenden Stosswellen erzeugen die Texturierung des Garns.The Texturierdüse 1 shown in Fig. 1 consists in a known manner of a cylindrical Nozzle body 2 with a nozzle head forming flange 3, one in the longitudinal axis of the Texturing 1 guided yarn channel 4, of the yarn to be treated in the direction of Arrows A is traversed, and from several, preferably two or three, under one acute angle α in the yarn channel 4 opening compressed air channels 5. The yarn channel 4 points a conically converging inlet part 6, a cylindrical middle part 7 and a conically opening outlet part 8. The compressed air channels 5 open into the cylindrical middle part 7 of the yarn channel, the immediately after the confluence of the compressed air channels 5 in the conical outlet part 8 passes. The compressed air channels 5 are via a compressed air supply line. 9 (Fig. 2) fed with highly compressed air, which is symbolized by an arrow P, and they blow into the yarn channel 4, wherein in the conical outlet part 8 of the yarn channel 4th adjusts a supersonic flow. The resulting shock waves generate the Texturing of the yarn.

Fig. 2 zeigt eine schematische Darstellung einer die Texturierdüse 1 und die an einen Druckluftvorrat (nicht dargestellt) angeschlossene Druckluftzuleitung 9 umfassenden Garnbehandlungseinrichtung. Darstellungsgemäss ist in zwischen Druckluftzuleitung 9 und Texturierdüse 1, und zwar möglichst nahe an der Texturierdüse 1, ein durch ein beheiztes Rohr gebildetes Heizelement 10 angeordnet. Dieses kann direkt in die Druckluftzuleitung 9 eingesetzt oder durch ein spezielles Teil gebildet sein, welches an seinem einen Ende eine Zuleitung zur Texturierdüse 1 und an seinem anderen Ende einen Druckluftanschluss aufweist. Die Strömungsrichtung der Druckluft in der Druckluftzuleitung 9 ist mit einem Pfeil P bezeichnet.Fig. 2 shows a schematic representation of a Texturierdüse 1 and to a compressed air reservoir (not shown) connected compressed air supply 9 comprehensive yarn treatment device. Darstellungsgemäss is in between compressed air supply line 9 and texturing 1, and Although as close as possible to the texturing 1, a formed by a heated tube heating element 10 arranged. This can be used directly in the compressed air supply line 9 or by a be formed special part, which at its one end a supply line to the texturing 1 and at its other end has a compressed air connection. The flow direction of Compressed air in the compressed air supply line 9 is designated by an arrow P.

Um den bei der Luftblastexturierung gewünschten Effekt, nämlich die Umformung von strukturlosen Chemiefaser-Endlosgarnen in gekräuselte Garne mit einem in Griff und Aussehen "gespinstähnlichen" Aussehen, zu erreichen, werden relativ hohe Luftdrücke von 10 bar und mehr benötigt. Da aber viele Textilbetriebe, die noch nicht mit Lufttexturierung arbeiten, mit einer in der Regel auf 6 bar beschränkten Druckluftversorgung ausgerüstet sind, würde für diese Betriebe eine Umrüstung auf Lufttexturierung die Anschaffung einer neuen Druckluftversorgungmit höherem Druck bedeuten. Durch die in Fig. 2 dargestellte Garnbehandlungseinrichtung wird nun die Möglichkeit geschaffen, die bei der Luftblastexturierung gewünschten Effekte schon mit Luftdrücken im Bereich von 6 bar zu erreichen.To the desired effect in the Luftblastexturierung, namely the transformation of structureless Synthetic fiber endless yarns in curled yarns with a handle and appearance To achieve "spinstelike" appearance, relatively high air pressures of 10 bar and more needed. But as many textile companies that are not yet working with air texturing, with a usually limited to 6 bar compressed air supply would be for these companies upgraded to air texturing the purchase of a new compressed air supply mean higher pressure. By the yarn treatment device shown in Fig. 2 now the possibility is created, which is desired in the Luftblastexturierung To achieve effects even with air pressures in the range of 6 bar.

Ermöglicht wird dieser Fortschritt durch das in die Druckluftzuleitung 9 eingesetzte oder zwischen Druckluftzuleitung 9 und Texturierdüse 1 angeordnete Heizelement 10. Alternativ kann auch die Texturierdüse 1 oder deren Gehäuse geheizt werden. Das Heizelement 10 weist beispielsweise eine elektrische Widerstandsheizung mit einem Heizdraht, einer Heizpatrone einem Heizband oder dergleichen auf. Es ist aber auch eine Gasheizung oder eine elektrische Induktionsheizung denkbar.This progress is made possible by the inserted into the compressed air supply line 9 or between the compressed air supply line 9 and texturing 1 arranged heating element 10. Alternatively it is also possible to heat the texturing nozzle 1 or its housing. The heating element 10 has For example, an electrical resistance heater with a heating wire, a heating cartridge a heating tape or the like. But it is also a gas heater or an electric Induction heating conceivable.

Wenn man von einer bekannten Texturierdüse 1, die mit Druckluft mit einem Druck von 10 bar betrieben wird, ausgeht, dann reduziert sich bei Absenkung des Luftdrucks von 10 bar auf 6 bar die adiabate Arbeitsleistung um gut 40%, wobei sich einerseits der Energieträger Luftstrom und andererseits die Energiedicht reduziert. Um wieder das gewünschte Energieniveau zu erreichen, ist es erforderlich, der Luft eine bestimmte Energiemenge zuzuführen, was durch das Heizelement 10 erfolgt. Zusätzlich kann man zur Erhöhung des Energieträgers Luftstrom die verwendete Texturierdüse 1 durch eine grössere Düse mit einem höheren Luftdurchsatz ersetzen, wodurch ein Teil der Reduktion der adiabaten Arbeitsleistung kompensiert wird.If one of a known texturing 1, with compressed air at a pressure of 10 bar is operated, then reduced by lowering the air pressure from 10 bar to 6 bar the adiabatic work performance by a good 40%, whereby on the one hand the energy carrier air flow and On the other hand, the energy density is reduced. To return to the desired energy level reach, it is necessary to supply the air with a certain amount of energy, which by the Heating element 10 takes place. In addition, you can increase the energy carrier air flow the used texturing 1 through a larger nozzle with a higher air flow replace part of the reduction in adiabatic work performance.

Wenn beispielsweise einer Luftmenge von etwa 14'000 Nm3/h eine Leistung von 300 W zugeführt werden muss, dann muss die Luft um etwa 65° K aufgeheizt werden, wofür das Heizelement 10 bei einem Rohrinnnendurchmesser von 10mm eine Länge von etwa 200 mm und eine Temperatur von etwa 550° C aufweisen müsste.If, for example, a power of 300 W has to be supplied to an air quantity of approximately 14,000 Nm 3 / h, then the air must be heated by approximately 65 ° K., for which the heating element 10 has a length of approximately 200 mm and 10 mm inside diameter of 10 mm should have a temperature of about 550 ° C.

Bei einer kleineren Texturierdüse 1 mit weniger Luftdurchsatz ist bei gleicher Absenkung des Luftdrucks von 10 bar auf 6 bar eine deutlich geringere Erwärmung der Luft erforderlich, was mit einer Reduktion der Dimensionen und des Energieverbrauchs des Heizelements 10 verbunden ist. In a smaller Texturierdüse 1 with less air flow is at the same lowering of the Air pressure of 10 bar to 6 bar significantly less heating of the air required with a reduction in the dimensions and energy consumption of the heating element 10 connected is.

Bei Auswahl einer Düse, die bei reduziertem Druck einen deutlich höheren Luftverbrauch aufweist, könnte der geschilderte Effekt auch ohne Verwendung eines Heizelements 10 erzielt werden. Wegen der doch relativ hohen Kosten der Druckluft wäre diese Lösung gegenüber der Lösung mit dem Heizelement 10 aber wirtschaftlich weniger interessant.If you select a nozzle, which at reduced pressure significantly higher air consumption has the described effect could be achieved without the use of a heating element 10 become. Because of the relatively high cost of compressed air, this solution would be compared to the Solution with the heating element 10 but less economically interesting.
