Description

Die vorliegende Erfindung betrifft eine Anlage und ein Verfahren zur Herstellung eines Velours, bei dem ein Vlies von einem ersten zu einem zweiten Transportband übergeben wird, wobei zwischen den Transportbändern eine Vorrichtung angeordnet ist, die ausgebildet ist, einzelne Fasern oder Polschlingen aus einer Seite des Vlieses heraus zu drücken.The present invention relates to a system and a method for producing a velor, in which a fleece is transferred from a first to a second conveyor belt, a device being arranged between the conveyor belts, which device is designed to separate fibers or pile loops from one side of the fleece to push out.

Üblicherweise wird ein textiles Velours dadurch hergestellt, in dem einzelne Fasern mittels Nadeln aus dem Verbund herausgestoßen werden. Bei textilen Geweben werden Schlingen aus dem Verbund mittels Nadeln herausgedrückt und diese aufgeschnitten.A textile velor is usually produced by pushing individual fibers out of the composite using needles. In the case of textile fabrics, loops are pressed out of the composite using needles and these are cut open.

Die EP 0183952 B1 beschreibt ein Verfahren zur Herstellung einer strukturierten Velournadelfilzbahn, bei dem die Nadeln in eine endlos umlaufende Bürstenplatte eintauchen und dabei die Fasern aus dem Verbund herausdrücken.The EP 0183952 B1 describes a process for producing a structured velor needle felt web, in which the needles are immersed in an endlessly rotating brush plate and thereby push the fibers out of the composite.

Nachteilig ist, dass die Fasern oder Filamente durch die mechanische Beanspruchung der Nadeln mehr oder weniger stark geschädigt werden. Die scharfen Kanten und Spitzen der Nadeln erzeugen auch an den benachbarten Fasern Dünnstellen und Beschädigungen, die nicht aus dem Verbund ausgestoßen werden. Weiterhin besteht die Gefahr von Nadelbrüchen, wobei die abgebrochenen Nadeln im Endprodukt auffindbar sind. Ebenfalls von Nachteil ist, dass das Vlies eine gewisse Grundfestigkeit und damit ein vorbestimmtes Flächengewicht benötigt, damit es bei dieser Art der Weiterverarbeitung nicht beschädigt wird. Das Vlies benötigt Vliesstoffeigenschaften, wie beispielsweise eine Mindestzugfestigkeit und eine Abriebfestigkeit, damit es für die weitere Verarbeitung geeignet ist. Ein sehr dünnes Velours mit einem minimalen Flächengewicht ist nach diesem Verfahren nur sehr aufwändig herstellbar. Aufgrund der diskontinuierlichen Arbeitsweise der Nadelmaschine ist eine kontinuierliche Produktion mit hohen Arbeitsgeschwindigkeiten nicht möglich.The disadvantage is that the fibers or filaments are more or less severely damaged by the mechanical stress on the needles. The sharp edges and tips of the needles also create thin spots and damage on the neighboring fibers that are not ejected from the composite. There is also a risk of needle breaks, and the broken needles can be found in the end product. Another disadvantage is that the fleece has a certain Basic strength and thus a predetermined basis weight is required so that it is not damaged during this type of processing. The nonwoven needs nonwoven properties, such as a minimum tensile strength and abrasion resistance, so that it is suitable for further processing. A very thin velor with a minimal weight per unit area can only be produced with great effort using this method. Due to the discontinuous operation of the needle machine, continuous production at high working speeds is not possible.

Es ist Aufgabe der Erfindung ein alternatives Verfahren mit einer Vorrichtung zur Herstellung eines Velours bereitzustellen, dass die zuvor beschriebenen Nachteile nicht aufweist.It is the object of the invention to provide an alternative method with a device for producing a velor that does not have the disadvantages described above.

Diese Aufgabe wird ausgehend von einer Anlage gemäß dem Oberbegriff des Anspruches 1 in Verbindung mit den kennzeichnenden Merkmalen gelöst. Die Aufgabe wird ebenfalls durch ein erfindungsgemäßes Verfahren mit den Merkmalen nach Anspruch 10 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben.This object is achieved on the basis of a system according to the preamble of claim 1 in conjunction with the characterizing features. The object is also achieved by an inventive method with the features of claim 10. Advantageous developments of the invention are specified in the dependent claims.

Die Erfindung schließt die technische Lehre ein, dass ein Vlies von einem ersten zu einem zweiten Transportband übergeben wird, wobei zwischen den Transportbändern eine Vorrichtung angeordnet ist, die ausgebildet ist, einzelne Fasern oder Polschlingen aus einer Seite des Vlieses heraus zu drücken.The invention includes the technical teaching that a fleece is transferred from a first to a second conveyor belt, a device being arranged between the conveyor belts, which device is designed to press individual fibers or pile loops out of one side of the fleece.

Kerngedanke der Erfindung ist, dass die Vorrichtung im Bereich einer ersten Oberfläche des Vlieses mindestens einen Wasserbalken zur Erzeugung einer Vielzahl von Wasserstrahlen umfasst, sowie mindestens eine Auflagefläche für die zweite Oberfläche des Vlieses, wobei zumindest ein Teil der Auflagefläche als Bürste ausgebildet ist, und eine Absaugvorrichtung mit der zumindest einen Bürste zusammenwirkt.The main idea of the invention is that the device in the region of a first surface of the nonwoven comprises at least one water bar for generating a plurality of water jets, and at least one support surface for the second surface of the nonwoven, at least part of the support surface being designed as a brush, and one Suction device cooperates with the at least one brush.

Die Verwendung einer Wasserstrahlvernadelung ist trotz der Absaugung und Bereitstellung des Wassers eine kostengünstigere Variante als die bekannte Nadelmaschine. Diese ist vom Bauraum so aufwendig und teuer, dass die Nachrüstung einer bestehenden Anlage damit nicht möglich ist. Durch die Änderung bzw. Kürzung eines Transportbandes um rund 0,5m lässt sich mit geringem Aufwand eine bestehende Anlage umrüsten. Die Wasserstrahlvernadelung bzw. Verfestigung ermöglicht auch bei geringen Flächengewichten des Vlieses eine zuverlässige und qualitativ hochwertige Herstellung eines Velours. Die Fasern werden durch die Wasserstrahlen nicht mechanisch geschädigt und über die Variation von Wasserdruck und Austausch der Düsenplatten lassen sich sehr schnell Veloure unterschiedlicher Qualität herstellen, was durch den Austausch eines Nadelbettes nach dem Stand der Technik deutlich aufwendiger ist. Die Verwendung von Wasserstrahlen ermöglicht einen kontinuierlichen Produktionsfluss.The use of water jet needling is a cheaper option than the known needle machine, despite the suction and provision of the water. The installation space is so complex and expensive that it is not possible to retrofit an existing system. By changing or shortening a conveyor belt by around 0.5m, an existing system can be converted with little effort. The water jet needling or consolidation enables reliable and high-quality production of a velor even with low basis weights of the fleece. The fibers are not mechanically damaged by the water jets and by varying the water pressure and replacing the nozzle plates, velours of different quality can be produced very quickly, which is much more complex due to the replacement of a needle bed according to the prior art. The use of water jets enables a continuous flow of production.

Mit weiterem Vorteil ist die Auflagefläche unter dem zu verarbeitenden Vlies als rotierende Bürstenwalze ausgebildet, die einerseits mit der Arbeitsgeschwindigkeit der Anlage rotiert, gleichzeitig ausgebildet ist, die Wasserstrahlen abzusaugen. Mit diesem Verfahren lassen sich Veloure mit geringem Flächengewicht herstellen.Another advantage is that the support surface under the fleece to be processed is designed as a rotating brush roller which, on the one hand, rotates at the operating speed of the installation, and at the same time is designed to suck off the water jets. This process can be used to produce velor with a low weight.

Insbesondere bei leichten Vliesen kann mit einer hydrodynamischen Vorverfestigung, die mit einem Druck von 20 bis 100 bar erfolgen kann, eine höhere Prozesssicherheit und eine höhere Arbeitsgeschwindikgeit erzielt werden.In the case of lightweight nonwovens in particular, hydrodynamic pre-consolidation, which can be carried out at a pressure of 20 to 100 bar, can achieve higher process reliability and higher working speed.

Figur 1 zeigt eine Anlage 1 zur Herstellung eines Velours 2b, bei dem ein unverfestigtes Vlies 2a aus einer Vorverarbeitung, beispielsweise durch eine Krempel oder ein Spinnvliesverfahren hergestellt wird. Damit kann das Vlies 2a aus Stapelfasern mit natürlichen und/oder synthetischen Fasern bestehen, aus einem Nassvliesstoff oder einer Kombination aus den zuvor aufgeführten Fasern. Das Vlies 2a wird mittels eines Transportbandes 7 unter einen Wasserbalken 4 geführt und an ein weiteres Transportband 8 übergeben. Zwischen den Transportbändern 7, 8 ist unter dem Wasserbalken 4 eine Absaugvorrichtung 3 angeordnet, auf der das Vlies 2a aufliegt. Der Wasserbalken 4 weist eine Vielzahl von Düsen 5 auf, aus denen Wasserstrahlen 6 auf das Vlies 2a treffen. Die Wasserstrahlen 6 treffen mit einem Druck von 40 bis 200 bar auf das Vlies 2a auf und verdichten das Vlies 2a. Dabei drücken die Wasserstrahlen 6 einzelne Fasern bzw. Polschlingen aus der Unterseite des Vlieses teilweise2a heraus, so dass ein Velours 2b entsteht. Die Absaugvorrichtung 3 weist einen Absaugschlitz 3b auf, der die Wasserstrahlen 6 in eine Absaugkammer 3 durchlässt. Diese kann besaugt sein und führt das Wasser des Wasserbalkens 4 ab. Beidseitig des Absaugschlitzes 3b sind Bürsten 3c angeordnet, auf denen das Vlies 2a zwischen den Transportbändern 7, 8 aufliegt. Die Bürsten 3c bilden die Auflagefläche für das Vlies 2a für den Bereich der Wasserstrahlverarbeitung und ermöglichen das Austreten von einzelnen Fasern bzw. Polschlingen aus dem verdichteten Vlies 2a. Demnach wird eine vertikale Faser- bzw. Polschicht erzeugt, die aus der Unterseite des Vlieses 2a, also der den Wasserstrahlen 6 gegenüberliegenden Seite austritt. Alternativ zum durchgehenden Absaugschlitz 3b kann auch eine Platte mit Bürsten 3c versehen sein, wobei zwischen den einzelnen Bündeln von Bürsten 3c Absaugbohrungen angeordnet sein können. Die Bürsten 3c können aus einem harten Kunststoff oder Metalldrähten bestehen. Über das Transportband 8 wird der Velours 2b einer weiteren Verarbeitung zugeführt. Die Arbeitsbreite der Anlage 1 kann zwischen 0,1 m bis 3,8 m betragen, wobei der Wasserbalken 4 und die Absaugung 3 sich über die gesamte Arbeitsbreite erstrecken. Figure 1 shows a system 1 for the production of a velor 2b, in which an unconsolidated nonwoven 2a is produced from a preprocessing, for example by a carding machine or a spunbonding process. The fleece 2a can thus consist of staple fibers with natural and / or synthetic fibers, of a wet nonwoven or a combination of the fibers listed above. The fleece 2a is guided by a conveyor belt 7 under a water bar 4 and transferred to another conveyor belt 8. Between the conveyor belts 7, 8, a suction device 3 is arranged under the water bar 4, on which the fleece 2a rests. The water bar 4 has a plurality of nozzles 5, from which water jets 6 strike the fleece 2a. The water jets 6 hit the fleece 2a with a pressure of 40 to 200 bar and compress the fleece 2a. The water jets push 6 individual fibers or pile loops out of the underside of the fleece partially 2a so that a velor 2b is produced. The suction device 3 has a suction slot 3b which allows the water jets 6 to pass into a suction chamber 3. This can be suctioned and drains the water from the water bar 4. On both sides of the suction slit 3b are arranged brushes 3c on which the fleece 2a lies between the conveyor belts 7, 8. The brushes 3c form the contact surface for the fleece 2a for the area of water jet processing and enable individual fibers or pile loops to emerge from the compressed fleece 2a. Accordingly, a vertical fiber or pile layer is produced, which emerges from the underside of the fleece 2a, that is to say the side opposite the water jets 6. As an alternative to the continuous suction slot 3b, a plate can also be provided with brushes 3c, wherein suction bores can be arranged between the individual bundles of brushes 3c. The brushes 3c can consist of a hard plastic or metal wires. The velor 2b is fed to a further processing via the conveyor belt 8. The working width of the system 1 can be between 0.1 m and 3.8 m, the water bar 4 and the suction 3 extending over the entire working width.

Optional, als zuschaltbare Einheit kann in Arbeitsrichtung im Bereich vor dem Wasserbalken 4, mit dem das Velours erzeugt wird, mindestens ein weiterer Wasserbalken 20 mit einer Absaugung 23 angeordnet sein. Dieser Wasserbalken 20 wird mit einem geringeren Druck von beispielsweise 20 bis 100 bar betrieben, und kann insbesondere bei leichten Vliesen oder einer hohen Arbeitsgeschwindigkeit betrieben werden. Die Düsenreihe 21 kann eine höhere Düsendichte aufweisen, als die Düsenreihe 5 zur Bildung eines Velours. Auch die Düsendurchmesser können einen geringeren Durchmesser aufweisen, so dass hier mit feineren Wasserstrahlen 22 vorverfestigt wird, als mit dem Wasserbalken 4. Mit diesem mindestens einen Wasserbalken 20 kann eine Vorbefeuchtung oder Vorverfestigung des unverfestigten Vlieses 2a erfolgen, so dass eine höhere Prozesssicherheit und/oder eine höhere Arbeitsgeschwindigkeit der Anlage insbesondere bei Vliesen mit geringen Flächengewichten erzielt wird.Optionally, as a switchable unit, at least one further water bar 20 with a suction device 23 can be arranged in the working direction in the area in front of the water bar 4 with which the velor is produced. This water bar 20 is operated at a lower pressure of, for example, 20 to 100 bar, and can be operated in particular in the case of light nonwovens or a high working speed. The nozzle row 21 can have a higher nozzle density than the nozzle row 5 to form a velor. The nozzle diameter can also have a smaller diameter, so that pre-consolidation is carried out with finer water jets 22 than with the water bar 4. With this at least one water bar 20, pre-moistening or pre-consolidation of the unconsolidated fleece 2a can take place, so that greater process reliability and / or a higher operating speed of the system is achieved, especially with nonwovens with low basis weights.

Im Ausführungsbeispiel der Figur 2 sind mindestens zwei Wasserbalken 4 in Arbeitsrichtung hintereinander oberhalb, aber zwischen den Transportbändern 7, 8 angeordnet. Statt der Absaugvorrichtung 3 nach Figur 1 ist jedem Wasserbalken 4 eine Bürstenwalze 10 zugeordnet. Jede Bürstenwalze 10 kann eine Absaugkammer 10a und mehrere auf dem Umfang verteilte Absaugschlitze 10b aufweisen. Zwischen den Absaugschlitzen 10b sind Bürsten 10c angeordnet, die in Form von Einschubleisten in oder an der Bürstenwalze 10 austauschbar befestigbar sind. In diesem Ausführungsbeispiel weist jede Bürstenwalze 10 sechs Absaugschlitze 10b mit dazwischen angeordneten Bürsten 10c auf. Die Bürstenwalzen 10 sind vorzugsweise angetrieben und weisen die gleiche Umfangsgeschwindigkeit am äußeren Durchmesser der Bürsten 10c auf, wie die Arbeitsgeschwindigkeit des Vlieses. Im Gegensatz zum Ausführungsbeispiel der Figur 1 wird das hergestellte Velours 2b nicht über feststehende Bürsten gezogen, wodurch die Qualität insbesondere bei den geringen Flächengewichten leiden kann, sondern kontinuierlich durch die rotierenden Bürstenwalzen 10 fast reibungsfrei zum Transportband 8 bewegt.In the embodiment of the Figure 2 at least two water bars 4 are arranged one behind the other in the working direction, but between the conveyor belts 7, 8. Instead of the suction device 3 after Figure 1 a brush roller 10 is assigned to each water bar 4. Each brush roller 10 can have a suction chamber 10a and a plurality of suction slots 10b distributed over the circumference. Brushes 10c are arranged between the suction slots 10b and can be exchangeably fastened in the form of slide-in strips in or on the brush roller 10. In this exemplary embodiment, each brush roller 10 has six suction slots 10b with brushes 10c arranged between them. The brush rollers 10 are preferably driven and have the same peripheral speed on the outer diameter of the brushes 10c as the working speed of the fleece. In contrast to the embodiment of the Figure 1 the velor 2b produced is not pulled over fixed brushes, as a result of which the quality can suffer, particularly in the case of the low basis weights, but is continuously moved almost without friction to the conveyor belt 8 by the rotating brush rollers 10.

Alternativ zu den hier abgebildeten Bürstenwalzen 10 können die Bürsten auch bündelweise an der Bürstenwalze 10 angeordnet sein, wobei zwischen den Bürsten eine Vielzahl von nicht dargestellten Bohrungen angeordnet sind, über die das Wasser des Wasserbalkens abgesaugt wird. Auch in diesem Ausführungsbeispiel werden die Wasserbalken 4 mit einem Druck von 40 bis 200 bar betrieben.As an alternative to the brush rollers 10 shown here, the brushes can also be arranged in bundles on the brush roller 10, with a plurality of bores (not shown) being arranged between the brushes, through which the water of the water bar is suctioned off. In this embodiment too, the water bars 4 are operated at a pressure of 40 to 200 bar.

Statt der Bürstenwalze 10 kann auch ein umlaufendes perforiertes Transportband mit einem Bürstenbelag verwendet werden, wobei dann unterhalb der Auflagefläche für das Vlies des Transportbandes eine Absaugung einzurichten ist.Instead of the brush roller 10, a circumferential perforated conveyor belt with a brush covering can also be used, in which case suction must be set up below the support surface for the fleece of the conveyor belt.

Auch dieses Ausführungsbeispiel weist optional als zuschaltbare Einheit, mindestens einen weiteren Wasserbalken 20 mit einer Absaugung 23 in Arbeitsrichtung im Bereich vor dem Wasserbalken 4 auf, mit dem das Velours erzeugt wird. Dieser Wasserbalken 20 wird mit einem geringeren Druck von beispielsweise 20 bis 100 bar betrieben, und kann insbesondere bei leichten Vliesen oder einer hohen Arbeitsgeschwindigkeit betrieben werden. Die Düsenreihe 21 kann eine höhere Düsendichte aufweisen, als die Düsenreihe 5 zur Bildung eines Velours. Auch die Düsendurchmesser können einen geringeren Durchmesser aufweisen, so dass hier mit feineren Wasserstrahlen 22 vorverfestigt wird, als mit dem Wasserbalken 4. Mit diesem mindestens einen Wasserbalken 20 kann eine Vorbefeuchtung oder Vorverfestigung des unverfestigten Vlieses 2a erfolgen, so dass eine höhere Prozesssicherheit und/oder eine höhere Arbeitsgeschwindigkeit der Anlage insbesondere bei Vliesen mit geringen Flächengewichten erzielt wird.This exemplary embodiment also optionally has, as a switchable unit, at least one further water bar 20 with a suction 23 in the working direction in the area in front of the water bar 4 with which the velor is produced. This water bar 20 is operated at a lower pressure of, for example, 20 to 100 bar, and can be operated in particular in the case of light nonwovens or a high working speed. The nozzle row 21 can have a higher nozzle density than the nozzle row 5 to form a velor. The nozzle diameters can also have a smaller diameter, so that pre-consolidation is carried out with finer water jets 22 than with the water bar 4. The at least one water bar 20 can be used for pre-moistening or pre-consolidation of the unconsolidated fleece 2a, so that greater process reliability and / or a higher operating speed of the system is achieved, especially with nonwovens with low basis weights.

In dem Ausführungsbeispiel der Figur 3 erfolgt die Beaufschlagung des Vlieses durch die Wasserstrahlen 6 von unten, da das Vlies unterhalb einer drehenden Bürstenwalze 10 geführt wird. Auch diese Bürstenwalze weist eine nicht weiter bezeichnete Absaugkammer und Absaugschlitze oder Absaugbohrungen auf, durch die zumindest ein Teil des Wassers vom Wasserbalken 4 abgeführt werden kann. Die dann entstehende Schicht eines Velours 2b liegt mit den Polfasern nicht mehr auf dem Transportband 8 auf. Auch dieses Ausführungsbeispiel kann eine Vorbefeuchtung oder Vorverfestigung mit mindestens einem weiteren Wasserbalken 20 mit Zubehör vorsehen, der mit einem geringeren Druck betrieben wird, als der Wasserbalken 4.In the embodiment of the Figure 3 the fleece is acted upon by the water jets 6 from below, since the fleece is guided below a rotating brush roller 10. This brush roller also has an unspecified suction chamber and suction slots or suction bores through which at least part of the water can be removed from the water bar 4. The then created layer of a velor 2b no longer lies on the conveyor belt 8 with the pile fibers. This exemplary embodiment can also provide a pre-moistening or pre-consolidation with at least one further water bar 20 with accessories, which is operated at a lower pressure than the water bar 4.

Mit der erfindungsgemäßen Anlage 1 der Ausführungsbeispiele der Figuren 1 bis 3 können Vliese mit einem Flächengewicht von 50 g/m2 bis 500 g/m2 verarbeitet werden. Insbesondere bei Verwendung einer Vorverfestigung kann die Arbeitsgeschwindigkeit bis zu 300m/min betragen. Vorzugsweise weisen die Fasern des Vlieses mindestens eine Länge von 20 mm auf. Die über der Bürstenwalze 10 oder der Absaugvorrichtung 3 vorstehende Länge der einzelnen Bürsten kann bis zu 15 mm betragen.With the system 1 of the embodiments of the invention Figures 1 to 3 nonwovens with a basis weight of 50 g / m 2 to 500 g / m 2 can be processed. Especially when using a Pre-consolidation, the working speed can be up to 300m / min. The fibers of the nonwoven preferably have a length of at least 20 mm. The length of the individual brushes protruding above the brush roller 10 or the suction device 3 can be up to 15 mm.

Die Erfindung beschränkt sich in ihrer Ausführung nicht auf das vorstehend angegebene bevorzugte Ausführungsbeispiel. Vielmehr ist eine Anzahl von Varianten denkbar, welche von der dargestellten Lösung auch bei grundsätzlich anders gearteten Ausführungen Gebrauch macht. Sämtliche aus den Ansprüchen, der Beschreibung oder den Zeichnungen hervorgehenden Merkmale und/oder Vorteile, einschließlich konstruktiver Einzelheiten oder räumlicher Anordnungen, können sowohl für sich als auch in den verschiedensten Kombinationen erfindungswesentlich sein.The embodiment of the invention is not limited to the preferred exemplary embodiment specified above. Rather, a number of variants are conceivable which make use of the solution shown, even in the case of fundamentally different types. All of the features and / or advantages arising from the claims, the description or the drawings, including structural details or spatial arrangements, can be essential to the invention both individually and in the most varied of combinations.
