Definitions
- the invention relates to a device for interlacing multifilament yarns according to the preamble of claim 1.
- the object of the invention is to design this device in such a way that, in comparison with known devices, a more uniform interlacing of multifilament yarns, in particular more uniform distances between the successive interlacing points, and a higher interlacing density, measured in interlacing points per meter, can be achieved. Furthermore, the formation of many and regular strong swirling points per meter or the formation of many and regular weak swirling points per meter should be possible, as desired.
- the object is achieved in the device according to the invention in that the two wall surfaces are curved so convexly on average with the plane of symmetry that the distance between the two wall surfaces measured in the plane of symmetry gradually decreases from a minimum at the mouth of the blowing nozzle towards both ends of the yarn channel increases.
- the energy of the fluid usually air, supplied through the blowing nozzle and flowing out through the yarn channel, has an adverse effect on the intermingled yarn, for example by dissolving weak intermingling points and thereby making the intermingling irregular and at the same time reducing the intermingling density.
- the thread tension in the yarn section moving past the mouth of the blow nozzle is additionally increased by the fluid flowing out toward both ends of the yarn channel, which makes the intermingling more difficult.
- Document DE-A-2917218 describes a generic intermingling device in which the one wall surface of the yarn channel, in which a blowing nozzle opens, is convexly curved in the plane of symmetry. This is supposed to be achieved that the yarn can be passed over the mouth of the blow nozzle in a non-linear way.
- both wall surfaces of the yarn channel are convexly curved in the plane of symmetry.
- the distance measured in the plane of symmetry between the two wall surfaces toward the ends of the yarn channel can increase more with the same radius of curvature than with only one curved wall surface.
- Swirling devices are usually designed in such a way that in the vicinity of the mouth of the blowing nozzle only an insignificantly higher pressure than the ambient pressure prevailing outside the device is formed. This is the only way to effectively use the energy gradient in the device.
- the velocity of the outflowing medium has to be reduced because the enlargement of the cross-sectional area towards the ends of the yarn channel gradually takes place so that the flow does not detach from the walls of the yarn channel.
- the width of the yarn channel preferably remains essentially constant over the entire length of the yarn channel. Maintaining the optimal yarn channel width results in a better quality of the interlacing and in particular a high swirl density.
- the blow jet divides the filament bundle into two approximately equal-sized bundles when they are pressed against the second wall surface, which only come together again at a certain distance from the blower nozzle to the intermingling nodes forming on both sides of the blower nozzle mouth. A further spreading of the two filament bundles in a yarn channel, which would widen towards the ends, would cause the swirl knots to form further away from the blow nozzle. This would reduce the turbulence density and the distance between the turbulence points would be greater.
- a device for intermingling multifilament yarns has a two-part body with a nozzle body part 1 and a baffle body part 2, which is attached to the nozzle body part 1 interchangeably by means of a screw 3 and two centering pins 4 and 5.
- a continuous yarn channel 6 extends through the two-part body 1, 2 and is delimited by a first wall surface 7 with a concave cross section, formed by a groove in the nozzle body part 1, and by a second hollow wall surface 8, formed by a groove in the impact body part 2
- the two wall surfaces 7 and 8 are each symmetrical with respect to a plane of symmetry which is identical to the sectional plane AA in FIG.
- the nozzle body part 1 contains a blowing nozzle 9, which is approximately in the middle the length of the yarn channel 6 opens laterally into the yarn channel.
- the mouth of the blowing nozzle 9 lies in the first wall surface 7.
- the second wall surface 8 lies opposite the opening of the blowing nozzle 9.
- the axis of the blowing nozzle 9 suitably lies in the plane of symmetry A - A.
- the nozzle body part 1 could also contain more than one blow nozzle.
- each blowing nozzle could be symmetrical with respect to the plane of symmetry A - A or, for example, two blowing nozzles could also be arranged symmetrically to one another on both sides of the plane A - A.
- the first wall surface 7 and the second wall surface 8 are curved in section with the plane of symmetry A - A as shown in FIG. 3 such that the distance between the two wall surfaces 7 and 8 measured in the plane of symmetry A - A is at a minimum at the mouth the blowing nozzle 9 gradually increases towards both ends of the yarn channel 6.
- the width of the yarn channel 6 measured perpendicular to the plane of symmetry A - A remains constant over the entire length of the yarn channel
- the cross-sectional area of the yarn channel increases from a minimum size at the mouth of the blowing nozzle 9 towards both ends of the yarn channel, for example except for 1.2 to 4 times the minimum size, preferably 1.5 to 2 times the minimum size.
- the curvature of the first wall surface 7 extends in such a way that the flow of the blowing medium from the mouth of the blowing nozzle 9 to the ends of the yarn channel 6 does not detach from the wall surface 7.
- the curve has no kinks, which means that the first derivative of the function mentioned is also a continuous function.
- the curvature of the curve should preferably not change abruptly; in other words, the second should also Deriving the function represented by the curve should preferably be a continuous function (without jumps).
- the second wall surface 8 is curved on average with the plane of symmetry.
- the curvature of the second wall surface 8 runs continuously in the same way as described above for the first wall surface 7, so that the flow does not separate from the second wall surface 8 either.
- a continuous threading slot 10 opens laterally into the yarn channel 6 between the two wall surfaces 7 and 8.
- the threading slot 10 lies between flat surfaces of the nozzle body part 1 and the impact body part 2.
- the yarn channel 6 ends at both ends in a groove 11 or 12.
- thread guide pins 13 or 14 are inserted outside the ends of the yarn channel, e.g. Sapphire pins that extend across grooves 11 and 12, respectively.
- a multifilament yarn M (FIG. 3), which in operation runs through the yarn channel 6 and is swirled by the blowing medium entering the yarn channel 6 from the blowing nozzle 9, is guided very precisely in the yarn channel 6.
- the thread guide pins have not been shown in FIG. 4.
- the second wall surface 8 extends beyond the ends of the yarn channel 6 to the outside.
- the first wall surface 7 is approximately V-shaped in cross-section with a rounded transition between the two V-legs. In other embodiments, the first wall surface could be approximately semicircular in cross section. Furthermore, the threading slot 10 could be omitted if desired.
Description
Die Erfindung bezieht sich auf eine Vorrichtung zum Verwirbeln von Multifilamentgarnen gemäss dem Oberbegriff des Patentanspruchs 1.The invention relates to a device for interlacing multifilament yarns according to the preamble of
Die Aufgabe der Erfindung besteht darin, diese Vorrichtung derart auszubilden, dass damit im Vergleich mit bekannten Vorrichtungen eine gleichmässigere Verwirbelung von Multifilamentgarnen, insbesondere gleichmässigere Abstände zwischen den aufeinanderfolgenden Verwirbelungsstellen, und eine höhere Verwirbelungsdichte, gemessen in Verwirbelungsstellen pro Meter, erzielt werden können. Ferner soll je nach Wunsch die Bildung vieler und regelmässiger starker Verwirbelungsstellen pro Meter oder die Bildung vieler und regelmässiger schwacher Verwirbelungsstellen pro Meter möglich sein.The object of the invention is to design this device in such a way that, in comparison with known devices, a more uniform interlacing of multifilament yarns, in particular more uniform distances between the successive interlacing points, and a higher interlacing density, measured in interlacing points per meter, can be achieved. Furthermore, the formation of many and regular strong swirling points per meter or the formation of many and regular weak swirling points per meter should be possible, as desired.
Die Aufgabe wird in der erfindungsgemässen Vorrichtung dadurch gelöst, dass die beiden Wandflächen im Schnitt mit der Symmetrieebene derart konvex gekrümmt sind, dass der in der Symmetrieebene gemessene Abstand zwischen den beiden Wandflächen von einem Minimum bei der Mündung der Blasdüse gegen beide Enden des Garnkanals hin allmählich zunimmt.The object is achieved in the device according to the invention in that the two wall surfaces are curved so convexly on average with the plane of symmetry that the distance between the two wall surfaces measured in the plane of symmetry gradually decreases from a minimum at the mouth of the blowing nozzle towards both ends of the yarn channel increases.
In bekannten Verwirbelungsvorrichtungen übt die Energie des durch die Blasdüse zugeführten und durch den Garnkanal abströmenden Fluids, zumeist Luft, eine nachteilige Wirkung auf das verwirbelte Garn aus, indem sie zum Beispiel schwache Verwirbelungsstellen wieder auflöst und dadurch die Verwirbelung unregelmässig macht und gleichzeitig die Verwirbelungsdichte herabsetzt. Auch wird die Fadenspannung in dem an der Mündung der Blasdüse vorbeibewegten Garnabschnitt durch das nach beiden Enden des Garnkanals hin abströmende Fluid zusätzlich erhöht, was die Verwirbelung erschwert.In known intermingling devices, the energy of the fluid, usually air, supplied through the blowing nozzle and flowing out through the yarn channel, has an adverse effect on the intermingled yarn, for example by dissolving weak intermingling points and thereby making the intermingling irregular and at the same time reducing the intermingling density. The thread tension in the yarn section moving past the mouth of the blow nozzle is additionally increased by the fluid flowing out toward both ends of the yarn channel, which makes the intermingling more difficult.
Im Dokument DE-A-2917218 ist eine gattungsgemäße Verwirbelungsvorrichtung beschrieben, in der die eine Wandfläche des Garnkanals, in welcher eine Blasdüse mündet, in der Symmetrieebene konvex gekrümmt ist. Damit soll erreicht werden, dass das Garn auf einem nicht geradlinigen Weg über die Mündung der Blasdüse geführt werden kann.Document DE-A-2917218 describes a generic intermingling device in which the one wall surface of the yarn channel, in which a blowing nozzle opens, is convexly curved in the plane of symmetry. This is supposed to be achieved that the yarn can be passed over the mouth of the blow nozzle in a non-linear way.
Demgegenüber sind in der Vorrichtung gemäss vorliegender Erfindung beide Wandflächen des Garnkanals in der Symmetrieebene konvex gekrümmt. Dadurch kann der in der Symmetrieebene gemessene Abstand zwischen den beiden Wandflächen gegen die Enden des Garnkanals hin bei gleichem Krümmungsradius stärker zunehmen als mit nur einer gekrümmten Wandfläche.In contrast, in the device according to the present invention, both wall surfaces of the yarn channel are convexly curved in the plane of symmetry. As a result, the distance measured in the plane of symmetry between the two wall surfaces toward the ends of the yarn channel can increase more with the same radius of curvature than with only one curved wall surface.
In der erfindungsgemässen Vorrichtung ergibt sich durch die Vergrösserung des Abstandes zwischen den Wandflächen gegen die Enden des Garnkanals hin, wenn die Breite des Garnkanals in der bevorzugten Weise etwa konstant bleibt, eine entsprechende Vergrösserung der Querschnittsfläche des Garnkanals gegen die Enden hin. Verwirbelungsvorrichtungen werden üblicherweise so ausgelegt, dass sich in der Nähe der Mündung der Blasdüse nur ein unwesentlich höherer Druck als der ausserhalb der Vorrichtung herrschende Umgebungsdruck bildet. Nur so kann das Energiegefälle in der Vorrichtung effektiv genutzt werden. In der erfindungsgemässen Vorrichtung muss daher durch die Vergrösserung der Querschnittsfläche des Garnkanals gegen die Enden hin, da praktisch keine Druckabsenkung mehr möglich ist, nach der Kontinuitätsgleichung von Bernoulli eine Reduktion der Geschwindigkeit des abströmenden Mediums eintreten, weil die Vergrösserung der Querschnittsfläche gegen die Enden des Garnkanals hin allmählich erfolgt, so dass sich die Strömung nicht von den Wänden des Garnkanals ablöst. Die Geschwindigkeit geht in der Energieformel
Die Breite des Garnkanals, senkrecht zur Symmetrieebene gemessen, bleibt wie schon erwähnt vorzugsweise über die ganze Länge des Garnkanals im wesentlichen konstant. Die Beibehaltung der optimalen Garnkanalbreite bewirkt eine bessere Qualität der Verwirbelung und insbesondere eine hohe Verwirbelungsdichte. Der Blasstrahl teilt das Filamentbündel im Moment des Anpressens an die zweite Wandfläche in zwei etwa gleichgrosse Bündel auf, die erst in einem gewissen Abstand von der Blasdüse zu den beiderseits der Blasdüsenmündung sich bildenden Verwirbelungsknoten wieder zusammenfinden. Ein weiteres Spreizen der beiden Filamentbündel in einem Garnkanal, der sich gegen die Enden hin verbreitern würde, würde die Bildung der Verwirbelungsknoten weiter von der Blasdüse weg bewirken. Dadurch würde die Verwirbelungsdichte herabgesetzt, der Abstand zwischen den Verwirbelungsstellen würde grösser.As already mentioned, the width of the yarn channel, measured perpendicular to the plane of symmetry, preferably remains essentially constant over the entire length of the yarn channel. Maintaining the optimal yarn channel width results in a better quality of the interlacing and in particular a high swirl density. The blow jet divides the filament bundle into two approximately equal-sized bundles when they are pressed against the second wall surface, which only come together again at a certain distance from the blower nozzle to the intermingling nodes forming on both sides of the blower nozzle mouth. A further spreading of the two filament bundles in a yarn channel, which would widen towards the ends, would cause the swirl knots to form further away from the blow nozzle. This would reduce the turbulence density and the distance between the turbulence points would be greater.

Gemäss der Zeichnung besitzt eine Vorrichtung zum Verwirbeln von Multifilamentgarnen einen zweiteiligen Körper mit einem Düsenkörperteil 1 und einem Prallkörperteil 2, der mittels einer Schraube 3 und zweier Zentrierstifte 4 und 5 auswechselbar auf dem Düsenkörperteil 1 befestigt ist. Durch den zweiteiligen Körper 1, 2 erstreckt sich ein durchgehender Garnkanal 6, der begrenzt ist durch eine erste, im Querschnitt konkave Wandfläche 7, gebildet von einer Nut im Düsenkörperteil 1, und durch eine zweite hohle Wandfläche 8, gebildet von einer Nut im Prallkörperteil 2. Die beiden Wandflächen 7 und 8 sind je symmetrisch bezüglich einer Symmetrieebene, die mit der Schnittebene A - A in Fig. 2 identisch ist. Der Düsenkörperteil 1 enthält eine Blasdüse 9, die etwa in der Mitte der Länge des Garnkanals 6 seitlich in den Garnkanal einmündet. Die Mündung der Blasdüse 9 liegt in der ersten Wandfläche 7. Die zweite Wandfläche 8 liegt der Mündung der Blasdüse 9 gegenüber. Die Achse der Blasdüse 9 liegt zweckmässig in der Symmetrieebene A - A.According to the drawing, a device for intermingling multifilament yarns has a two-part body with a
Der Düsenkörperteil 1 könnte auch mehr als eine Blasdüse enthalten. In einem solchen Fall könnte jede Blasdüse bezüglich der Symmetrieebene A - A symmetrisch sein oder könnten auch beispielsweise zwei Blasdüsen zueinander symmetrisch auf beiden Seiten der Ebene A - A angeordnet sein.The
Die erste Wandfläche 7 und die zweite Wandfläche 8 sind im Schnitt mit der Symmetrieebene A - A wie in Fig. 3 dargestellt derart gekrümmt, dass der in der Symmetrieebene A - A gemessene Abstand zwischen den beiden Wandflächen 7 und 8 von einem Minimum bei der Mündung der Blasdüse 9 gegen beide Enden des Garnkanals 6 hin allmählich zunimmt. Dadurch nimmt, obwohl die senkrecht zur Symmetrieebene A - A gemessene Breite des Garnkanals 6 über die ganze Länge des Garnkanals konstant bleibt, die Querschnittsfläche des Garnkanals von einer Minimalgrösse bei der Mündung der Blasdüse 9 gegen beide Enden des Garnkanals hin zu, beispielsweise bis auf das 1,2- bis 4-fache der Minimalgrösse, vorzugsweise auf das 1,5- bis 2-fache der Minimalgrösse.The
Die Krümmung der ersten Wandfläche 7 verläuft derart, dass sich die Strömung des Blasmediums von der Mündung der Blasdüse 9 zu den Enden des Garnkanals 6 nicht von der Wandfläche 7 ablöst. Das heisst zunächst, dass die erste Wandfläche 7 im Schnitt mit der Symmetrieebene A - A nach einer Kurve verläuft, die eine stetige Funktion in Abhängigkeit von der Entfernung von der Mündung der Blasdüse 9 darstellt. Die Kurve weist keine Knicke auf, das heisst, dass auch die erste Ableitung der genannten Funktion eine stetige Funktion ist. Ferner sollte sich auch die Krümmung der Kurve vorzugsweise nicht sprunghaft ändern, es sollte mit anderen Worten auch die zweite Ableitung der von der Kurve dargestellten Funktion vorzugsweise eine stetige Funktion (ohne Sprünge) sein.The curvature of the
Ebenso wie die erste Wandfläche 7 ist auch die zweite Wandfläche 8 im Schnitt mit der Symmetrieebene gekrümmt. Die Krümmung der zweiten Wandfläche 8 verläuft dabei in gleicher Weise stetig wie vorstehend für die erste Wandfläche 7 beschrieben, so dass sich auch von der zweiten Wandfläche 8 die Strömung nicht ablöst.Like the
In der dargestellten Ausführungsform mündet in den Garnkanal 6 zwischen den beiden Wandflächen 7 und 8 seitlich ein durchgehender Einfädelschlitz 10. Der Einfädelschlitz 10 liegt zwischen ebenen Oberflächen des Düsenkörperteils 1 und des Prallkörperteils 2.In the embodiment shown, a
Im Düsenkörperteil 1 endet der Garnkanal 6 beiderends in je einer Nut 11 bzw. 12. In den Düsenkörperteil 1 sind ausserhalb der Enden des Garnkanals 6 Fadenführerstifte 13 bzw. 14 eingesetzt, z.B. Saphirstifte, die sich quer durch die Nuten 11 bzw. 12 erstrecken. Mit diesen Fadenführerstiften 13 und 14 ist ein Multifilamentgarn M (Fig. 3), das im Betrieb durch den Garnkanal 6 läuft und durch das aus der Blasdüse 9 in den Garnkanal 6 eintretende Blasmedium verwirbelt wird, im Garnkanal 6 sehr genau geführt. In Fig. 4 sind die Fadenführerstifte nicht eingezeichnet worden. Die zweite Wandfläche 8 erstreckt sich über die Enden des Garnkanals 6 hinaus nach aussen.In the
In der dargestellten Ausführungsform ist die erste Wandfläche 7 im Querschnitt etwa V-förmig mit gerundetem Uebergang zwischen den beiden V-Schenkeln. In anderen Ausführungsformen könnte die erste Wandfläche im Querschnitt etwa halbkreisförmig sein. Ferner könnte gewünschtenfalls der Einfädelschlitz 10 weggelassen werden.In the embodiment shown, the
