Description

Gegenstand der Erfindung ist eine Vorrichtung zur Herstellung einer durch Wasserstrahlbehandlung verfestigten und/oder strukturierten Warenbahn, bestehend aus einem Vlies oder Gewirke aus synthetischen Stapelfasern, natürlichen Fasern, Endlosfasern oder Mischungen der genannten Fasern.The invention relates to a device for producing a web of material solidified by water jet treatment and / or structured, consisting of a nonwoven or knitted fabric of synthetic staple fibers, natural fibers, continuous fibers or mixtures of said fibers.

Aus der DE 101 52 075 A1 ist bereits eine Vorrichtung zur Erzeugung dreidimensionaler farbloser Muster einer Warenbahn mittels Wasservernadelung bekannt. Eine Vorrichtung zur Herstellung von perforierten Vliesstoffen durch mit hohem Druck beaufschlagte Wasserstrahlen oder heiße Luft wird in der EP 0 511 025 A1 beschrieben. Auch in den EP 0 223 614 B1 , EP 0 215 684 B1 und EP 1 001 964 B1 werden Vorrichtungen beschrieben, die ein vorgefertigtes Vlies mit einer Lochstruktur versehen. Dabei wird durch mit Druck beaufschlagte Wasserstrahlen der Vliesbahn, die sich auf einem mit empor stehenden plastischen Erhöhungen versehenen Band oder auf einer mit empor stehenden plastischen Erhöhungen versehenen Trommel befindet, eine Lochstruktur verliehen. Darüber hinaus sind aus der EP 0 705 932 B1 Stoffe bekannt, die sowohl reliefartige Strukturen als auch Löcher in einer ganz bestimmten Anordnung aufweisen.From the DE 101 52 075 A1 already a device for producing three-dimensional colorless pattern of a web by means of water needling known. An apparatus for producing perforated nonwoven fabrics by high pressure jets of water or hot air is disclosed in US Pat EP 0 511 025 A1 described. Also in the EP 0 223 614 B1 . EP 0 215 684 B1 and EP 1 001 964 B1 describes devices that provide a prefabricated nonwoven with a hole structure. In this case, a perforated structure is imparted by pressurized water jets of the nonwoven web, which is located on a belt provided with upstanding plastic elevations or on a drum provided with upstanding plastic elevations. In addition, from the EP 0 705 932 B1 Substances are known which have both relief-like structures and holes in a very specific arrangement.

Aufgabe der vorliegenden Erfindung ist es, eine Vorrichtung zur entwickeln, die sowohl zur Strukturgebung einer Warenbahn als auch zu deren Verfestigung eingesetzt werden kann. Diese Aufgabe lässt sich durch unterschiedliche Schrumpfsiebe lösen, die als endloser Schlauch auf eine Lochtrommel aufgeschrumpft werden. Mit derartigen unterschiedlichen Schrumpfsieben können zwei ganz verschiedene Funktionen der erfindungsgemäßen Vorrichtung erfüllt werden, nämlich einmal eine Strukturgebung der Warenbahn und andererseits deren Verfestigung.The object of the present invention is to develop a device which can be used both for structuring a material web and for solidifying it. This task can be solved by different shrink sieves, which are shrunk as an endless tube on a perforated drum. With such different shrink sieves two completely different functions of the device according to the invention can be fulfilled namely, a structuring of the web and, on the other hand, its consolidation.

Gegenstand der Erfindung ist deshalb eine Vorrichtung zur Herstellung einer durch Wasserstrahlbehandlung verfestigen und/oder strukturierten Warenbahn, bestehend aus einem Vlies oder einem Gewirke aus synthetischen Fasern, natürlichen Fasern, Endlosfasern oder Mischungen der genannten Fasern, bei der auf einer Lochtrommel 1 ein grobes Untersieb 2 und darüber ein feineres Schrumpfsieb 3 angeordnet sind und das Schrumpfsieb aus einem Siebband besteht, das als endloser Schlauch aufgeschrumpft ist.The invention therefore relates to an apparatus for producing a fabric web which is solidified by water jet treatment and / or structured, consisting of a nonwoven or a knitted fabric of synthetic fibers, natural fibers, continuous fibers or mixtures of said fibers, in which a coarse lower wire 2 is provided on a perforated drum 1 and above a finer shrink sieve 3 are arranged and the shrink sieve consists of a sieve belt, which is shrunk in an endless tube.

Wird diese Vorrichtung zur Strukturgebung eingesetzt, werden grobe Schrumpfsiebe verwendet, die etwa 5 Drähte/cm haben (Kette und Schuss). Hierbei wird ein schon zuvor verfestigtes Vlies mit einer textilen Struktur versehen und zwar so, dass die Strukturen in Warenlaufrichtung und rechtwinklig dazu verlaufen. Dies wird durch ein grobes Schrumpfsieb erreicht, dessen schrumpffähige Kettfäden orthogonal um die Trommel herum verlaufen und deren nicht schrumpfende Schussfäden achsparallel zur Trommel angeordnet sind. Bei der so durchgeführten Strukturierung kann auch mit schwerer Ware, die mehr als 100 g/m2 aufweist, gearbeitet werden, weil ein Rückpralleffekt der bei der Vernadelung angewendeten Wasserstrahlen nicht auftritt und auch nicht erforderlich ist, da schwere Vliese für die energiereichen Wasserstrahlen eine Barriere darstellen und somit ein "Durchschießen" verhindern. Eine Verfestigung der Warenbahn wird bei dem so durchgeführten Strukturieren nicht erzielt, so dass das Vlies vorher schon seine Festigkeit erhalten haben muss.When this device is used for patterning, coarse shrink sieves are used which have about 5 wires / cm (warp and weft). Here, a previously solidified nonwoven fabric is provided with a textile structure in such a way that the structures run in the direction of travel and at right angles to it. This is achieved by a coarse shrink sieve whose shrinkable warp threads are orthogonal around the drum and whose non-shrinking weft threads are arranged axially parallel to the drum. In the structuring thus carried out can also with heavy goods, which has more than 100 g / m 2 , be worked because a rebound effect of the water jets used in the needling does not occur and is not required, since heavy nonwovens for the high-energy water jets a barrier represent and thus prevent a "shooting through". A solidification of the web is not achieved in the structuring thus carried out, so that the web must have previously received its strength.

Üblicherweise wird das zur Strukturierung eingesetzte Schrumpfsieb als letztes Band in der Anlage eingesetzt, da nach der Strukturierung keine weitere Vernadelungsstufe mehr verwendet werden kann. Jede weitere Vernadelung würde die erzeugte Struktur wieder zerstören. Bei dieser Verfahrensführung ist auch ein Endabsaugschlitz vorgesehen, der das nasse Vlies bestmöglichst entwässert, um die Ware mit einer definierten Restfeuchte in den nachfolgenden Trocknungsprozess oder andere Folgeprozesse zu fahren.Usually, the shrink screen used for structuring is used as the last belt in the system, since after structuring no further needling can be used more. Any further needling would destroy the structure created again. In this procedure, a Endabsaugschlitz is provided, the best way dewatering the wet web to drive the goods with a defined residual moisture in the subsequent drying process or other follow-up processes.

Eine weitere Anwendungsmöglichkeit der erfindungsgemäßen Vorrichtung besteht darin, dass ein auf die Lochtrommel aufgebrachtes Schrumpfsieb auch als Ersatz für die bisher zur Verfestigung eines leichten Vlieses (Flächengewicht kleiner als 100 g/m2) eingesetzte mikro-poröse Schale ersetzt werden kann.A further possible application of the device according to the invention is that a shrinkage screen applied to the perforated drum can also be replaced as a substitute for the microporous shell previously used for solidifying a light nonwoven (basis weight less than 100 g / m 2 ).

Der bisher übliche Einsatz der mikro-porösen Schale ist mit Nachteilen verbunden. Bei Verwendung einer MPS muss die Lochtrommel mit engen Toleranzen gefertigt werden, da die MPS mit wenig Spiel auf die Trommel geschoben werden muss, um im Betrieb nicht durch erhöhte Walkarbeit beschädigt zu werden. Wenn es gelingen würde, die MPS zum Beispiel durch ein Schrumpfsieb zu ersetzen, könnte die tragende Lochtrommel mit größeren Toleranzen gefertigt werden, da ein Schrumpfsieb größere Durchmesserunterschiede der Trommel ausgleichen kann. Hinzu kommt, dass ein Schrumpfsieb gegenüber einer MPS deutlich geringere Investitionskosten erfordert und ein beschädigtes oder verschlissenes Schrumpfsieb relativ einfach ausgetauscht werden kann, wogegen eine neue MPS aufgrund des Toleranzfeldes mit einem anderen Durchmesser geliefert wird und höchstwahrscheinlich nicht so gut auf die Trommel passt wie die bisher verwendete MPS:The hitherto customary use of the micro-porous shell is associated with disadvantages. When using an MPS, the hole drum must be manufactured with tight tolerances, since the MPS must be pushed onto the drum with little play so that it is not damaged by increased flexing during operation. For example, if it were possible to replace the MPS with a shrink sieve, the load bearing punch drum could be made to greater tolerances since a shrink wire can accommodate larger diameter differences in the drum. In addition, a shrink screen requires significantly less investment cost than an MPS and a damaged or worn shrink screen can be relatively easily replaced, whereas a new MPS due to the tolerance field is supplied with a different diameter and most likely will not fit as well on the drum as before used MPS:

Wird erfindungsgemäß jedoch ein Schrumpfsieb 3 eingesetzt, das Drähte mit Durchmessern von 0,15 bis 0,2 mm und 25 bis 45 Drähte/cm (Kette und Schuss) längs und quer zur Laufrichtung aufweist, dann werden hervorragende Verfestigungseffekte erzielt. Bei leichten Vliesen besteht die Gefahr, dass die energiereichen Wasserstrahlen, die mit einer Geschwindigkeit von mehr als 200 km/h auf das Vlies auftreffen, einfach das Vlies durchschlagen. Damit ist die kinetische Energie des Wasserstrahls wirkungslos und geht verloren. Das würde den Wirkungsgrad der Maschine senken und die aufzuwendende Energie pro kg Fertigware würde erheblich ansteigen.However, according to the present invention, when using a shrink wire 3 having wires with diameters of 0.15 to 0.2 mm and 25 to 45 wires / cm (warp and weft) along and in the direction of running, excellent solidification effects are obtained. For light nonwovens there is a risk that the high-energy water jets, which impinge on the fleece at a speed of more than 200 km / h, simply penetrate the fleece. Thus, the kinetic energy of the water jet is ineffective and is lost. This would reduce the efficiency of the machine and the energy required per kg of finished product would increase significantly.

Erfindungsgemäß wird nun aber die kinetische Energie der Wasserstrahlen dazu genutzt, die Lage der einzelnen Fasern zu ändern und damit die Festigkeit des vorher losen Faserverbandes zu erhöhen. Das wird erfindungsgemäß bei leichten Vliesen dadurch erreicht, dass auf der Trommel 3 ein sehr feines Schrumpfsieb aufgezogen wird und durch die feine Struktur eine homogene Oberfläche erreicht werden kann, an der ein Wasserstrahl auch wieder zurückprallt. Die mit hoher Geschwindigkeit auf das Vlies treffenden Wasserstrahlen passieren dieses, treffen dann auf das Schrumpfsieb 3 und werden von dort gegen das Vlies zurückgeworfen. Der dabei auftretende Rückpralleffekt führt dazu, dass das Vlies nun auch von der Unterseite vernadelt wird und dadurch wesentlich höhere Festigkeiten erzielt werden.According to the invention, however, the kinetic energy of the water jets is now used to change the position of the individual fibers and thus to increase the strength of the previously loose fiber structure. This is according to the invention light nonwovens achieved in that on the drum 3, a very fine shrinkage screen is mounted and the fine structure, a homogeneous surface can be achieved at which a water jet rebounds again. The water jets hitting the fleece at high speed pass through this, then hit the shrink sieve 3 and from there are thrown back against the fleece. The occurring rebound effect causes the fleece is now also needled from the bottom and thus significantly higher strengths are achieved.

Natürlich kann eine so verfestigte Warenbahn anschließend in eine Strukturierungsstufe laufen, die oben im Einzelnen beschrieben worden ist.Of course, such a consolidated web can then run into a structuring stage, which has been described in detail above.

In den in der erfindungsgemäßen Vorrichtung eingesetzten Siebbändern sind offenen Flächen zum Ableiten der aus den vielen Austrittsöffnungen eines Düsenbalkens mit Hochdruck aufgespritzten Flüssigkeit vorgesehen. Die schrumpffähigen Siebbänder enthalten Kett- und Schussfäden, die aus thermoplastischen Homo- oder Copolymerisaten bestehen können. Besonders vorteilhaft ist es allerdings, wenn das schrumpffähige Siebband Schussfäden enthält, die aus Metalldraht bestehen.In the screen belts used in the device according to the invention, open surfaces are provided for discharging the liquid sprayed from the many outlet openings of a nozzle beam at high pressure. The shrinkable screen belts contain warp and weft threads, which may consist of thermoplastic homo- or copolymers. However, it is particularly advantageous if the shrinkable screen belt contains weft threads, which consist of metal wire.

Außerdem kann in besonderen Fällen eine Vorrichtung besonders vorteilhaft sein, bei der zwischen das grobe Untersieb 2 und das Schrumpfsieb 3 ein weiteres Sieb eingefügt wird, so dass auf der Lochtrommel 1 insgesamt drei Siebe übereinander liegen. Das ist besonders bei großen Unterschieden in der Maschenweite und/oder der Drahtstärke des Untersiebes und des Schrumpfsiebes ratsam.In addition, in special cases, a device may be particularly advantageous in which a further sieve is inserted between the coarse lower sieve 2 and the shrink sieve 3 so that a total of three sieves are superimposed on the perforated drum 1. This is particularly advisable for large differences in the mesh size and / or the wire thickness of the bottom wire and the shrink screen.

Mit der erfindungsgemäßen Vorrichtung lässt sich zum Beispiel ein Vlies von 57 g/m2 herstellen, das bei einer Zusammensetzung aus Viskose/Polyester 70:30 und bei einer Produktionsgeschwindigkeit von 70 m/min folgende Kenndaten aufweist:With the device according to the invention, it is possible, for example, to produce a fleece of 57 g / m 2 , which has the following characteristics with a composition of viscose / polyester 70:30 and at a production speed of 70 m / min:

Bei Anwendung des erfindungsgemäßen Schrumpfsiebes wird eine Festigkeit von 93 N in Maschinenrichtung und eine Festigkeit von 20 N in Querrichtung bei einer Vliesdicke von 0,72 mm erzielt.When using the shrinkage screen according to the invention, a strength of 93 N in the machine direction and a strength of 20 N in the transverse direction is achieved with a nonwoven thickness of 0.72 mm.

Würde man eine derartige Warenbahn mit der üblichen mikro-porösen Schale herstellen, dann beobachtet man eine Festigkeit von 95 N in Maschinenrichtung und 20 N in Querrichtung sowie eine Vliesdicke von 0,73 mm.If one were to produce such a web with the usual micro-porous shell, then one observes a strength of 95 N in the machine direction and 20 N in the transverse direction and a web thickness of 0.73 mm.

Die beiliegende Fig. 1 zeigt schematisch den Aufbau der Trommel. Die unterste Schicht bildet die Lochtrommel 1. Über ihr liegt das grobe Untersieb 2, indem auch die Kettfäden 4 zu erkennen sind. Nach oben abgeschlossen wird die Schichtstruktur durch das Schrumpfsieb 3.The accompanying Fig. 1 shows schematically the structure of the drum. The lowermost layer forms the perforated drum 1. Above it lies the coarse lower wire 2, in which the warp threads 4 can also be seen. The layer structure is closed at the top by the shrink sieve 3.
