Verbundmaterial aus einem Vlies und einem einseitig beschichteten SubstratComposite material consisting of a fleece and a one-sided coated substrate

Anmelder: Renker GmbH & Co. KG, Kreuzsuer Str. 33, 5160 DürfenApplicant: Renker GmbH & Co. KG, Kreuzsuer Str. 33, 5160 Dürfen Gegenstand der Neuerung ist. ein flächenförmig&sThe subject of the innovation is a surface-like

Verbundsüsrialien aus mehreren ichich» -n sind generell beirannt. Herkömmliche Wirkpflaster sind Verbund: .terialien isit einer heilaktiven Schicht ^ind Traget,schichten. In der Rege} wird der direkte Kontakt der heüaktiven Schicht »&iacgr;&idiagr; mn- Haut dadurch verhindert, del über die heilaktive Schicht ein Gazematerial aufgelegt und an Rand &ugr;it d&j Trägermaterial z. B. vernäht wird. Dieses Verbundmaterial kanr anschließend nicht mehr in kleinere Formate geschnitten «erden, ohne die Verbindung des Gazematerials mit c_s Trägermaterial zumindest teilweise zu lösen.Composite materials made of several layers are generally used. Conventional plasters are composite materials with a healing layer and support layers. Direct contact between the healing layer and the skin is usually prevented by placing a gauze material over the healing layer and sewing it to the edge with the support material, for example. This composite material can then no longer be cut into smaller formats without at least partially breaking the connection between the gauze material and the support material.

Aufgabe der Neuerung ist es, ein Verbundmaterial aus mehreren Schichten zu schaffen, bei dem ein einseitig beschichtetes flächenförmiges Material so verändert wird, daß die einseitige Schicht mit einer relativ voluminösen durchlässigen Schicht gegen Berührungskontakt abgedeckt wird.The aim of the innovation is to create a composite material made up of several layers, in which a sheet-like material coated on one side is modified in such a way that the one-sided layer is covered with a relatively voluminous permeable layer to prevent contact.

Diese Aufgabe wird gelöst durch ein flächenförmiges Verbundmaterial mit mehreren Schichten, das dadurch gekennzeichnet ist, daß es aus einem Substrat, auf dessen Oberfläche eine dünne Metallschicht oder Schicht einer Metallverbindung angeordnet ist und einem auf die gegenüberliegende Substratoberfläche derart aufgenadelten Vlies besteht, daß ein Teil der Vliesfäden durch die beim Nadeln entstehende Perforierung des Substrates hindurch' geführt ist und auf der dünnen Metallschicht oder Metallverbindungsschicht eine Vliesschicht ausgebildet ist.This object is achieved by a sheet-like composite material with several layers, which is characterized in that it consists of a substrate, on the surface of which a thin metal layer or layer of a metal compound is arranged, and a fleece needled onto the opposite substrate surface in such a way that some of the fleece threads are guided through the perforation of the substrate created during needling and a fleece layer is formed on the thin metal layer or metal compound layer.

Auf diese Weise ist die Metallschicht vor direkter Berührung geschützt, aber flächenmäßig nicht vollständig abgedeckt. Durch die beim Kadeln entstehende Perforation der Trägerfolie wird das Verbündeter iai luftdurchlässig und atmungsAirtii. Vorzugsweise wird ein flächenförmiges flexibles Substrat für das VerbL-itLiaterial verwendet - so daS dieses als ein Wirkpflaster verwendet werden kann, wenn es sich bei der Metallschicht oder Metallverbindungsschicht um eine heilaktive Schicht handelt. Die neuerungsgemäße Ausbildung des Verbundmaterials ermöglicht bei Verwendung als Wirkpflaster eine flache Auflage auf die zu heilende Stelle unter Vermeidung des direkten Xontaktes zwischen der mit einem Metall oder einer Metallverbindung beschichteten Substratoberfläche und der zu heilenden Stelle, obwohl eine großflächige Auflage vorhanden ist. Der Abstand und die Dichte der abdeckenden Vliesschicht läßt sich über die Intensität beim Nadeln und über die Zahl der durch das Substrat hindurchgeführten Fäden einstellen.In this way, the metal layer is protected from direct contact, but not completely covered. The perforation of the carrier film during needling makes the material permeable to air and breathable. Preferably, a flat, flexible substrate is used for the composite material - so that it can be used as an active plaster if the metal layer or metal compound layer is a healing layer. The innovative design of the composite material enables it to be applied flatly to the area to be healed when used as an active plaster, avoiding direct contact between the substrate surface coated with a metal or metal compound and the area to be healed, even though a large area is covered. The distance and density of the covering fleece layer can be adjusted by the intensity of needling and the number of threads passed through the substrate.

Im Gegensatz zu bekannten Wirkpflastern aus Verbundmaterial kann das neuerungsgemäße, in Bahnform hergestellte, flächenförmige Verbundmaterial vor der Verwendung auf das gewünschte Format geschnitten werden, ohne daß sich die Verbindungen der einzelnen Schicht zn des Laminats voneinander lösen. Vorzugsweise besteht das Vlies aus Baumwolle, Viskose oder synthetischen Polymerfasern mit einem Flächengewicht von 100 bis 200 g/qm.In contrast to known active plasters made of composite material, the new, sheet-like composite material, which is produced in web form, can be cut to the desired format before use without the connections between the individual layers of the laminate coming apart. The fleece is preferably made of cotton, viscose or synthetic polymer fibers with a surface weight of 100 to 200 g/m².

Als Sttbstrat sind Celluloseschichten oder Kunststoffolien oder Gewebe in einer Dicke von 50 bis 150 &mgr;&pgr;&igr; geeignet. Geeignete Kunststoffe für Folien oder die bereits genannten flächenförmigen Substrate sind Polyethylenterephthalat, Polypropylen, Polyethylen.Cellulose layers or plastic films or fabrics with a thickness of 50 to 150 μια are suitable as a substrate. Suitable plastics for films or the sheet-like substrates already mentioned are polyethylene terephthalate, polypropylene, polyethylene.

Aul das Substrat wird vorzugsweise eine wenige /Um oder auch weniger dicke Metallschicht oder Schicht einer Metallverbindung aufgebracht. Die Schichtdicke ist ausreichend, um eine kompakte und möglichst gut reflektierende Schichtoberfläche auszubilden. Derartige Schichten lassen sich z. B. durch Kahtodenstrahlzerstäubung (Spufctertecnnik) der entsprechenden Metalle, Metalllegierungen, Oxiden oder Nitriden aufbringen. Das Aufbringen kann auch durch Aufdampfen im Vakuum erfolgen. Besonders bevorzugte Metalle für die Schicht sind Zinn, Eisen, Gold, Silber, Blei, Quecksilber, Kupfer oder Metallegierungen dieser Metalle, oder Oxide oder Nitride dieser Metalle. Es können auch Mischoxide oder Mischnitride der vorstehend genannten Metalle aufgebracht werden.A metal layer or layer of a metal compound a few µm or less thick is preferably applied to the substrate. The layer thickness is sufficient to form a compact and as highly reflective as possible layer surface. Such layers can be applied, for example, by cathode ray sputtering (sputtering technology) of the corresponding metals, metal alloys, oxides or nitrides. The application can also be carried out by vapor deposition in a vacuum. Particularly preferred metals for the layer are tin, iron, gold, silver, lead, mercury, copper or metal alloys of these metals, or oxides or nitrides of these metals. Mixed oxides or mixed nitrides of the above-mentioned metals can also be applied.

Die neuerungsgemäße Ausbildung des Verbundmaterials vermeidet bei Verwendung als Wirkpfiaster einen direkten Kontakt der Haut mit der Wirksubstanz und einen Hitzestau, indem ein hautverträgliches Vlies als Abstandhalterschicht zwischen der Metallschicht und der Oberfläche des Verbundmaterials ausgebildet ist, wobei diese Äbstandhaiterschichfc die heilaktive Schicht nur sehr wenig abdeckt.The innovative design of the composite material avoids direct contact of the skin with the active substance and heat build-up when used as an active plaster, as a skin-friendly fleece is designed as a spacer layer between the metal layer and the surface of the composite material, whereby this spacer layer only covers the healing layer to a very small extent.

Beim Verbinden des Substrats mit dem Vlies auf der unbeschichteten Seite durch Nadeln wird auf der beschichteten Seite ein Vliesanteil mit sehr geringem Volumengewicht ausgebildet. Durch die Anwendung der Nadelung als Verbindungstechnik werden nicht nur die benötigten Fäden durch das Substrat hindurchgezogen, sondern es wird auch das im Falle einer Kunststoffolie als Substrat diffusionsdichte Trägermaterial ausreichend perforiert. Die Verbindungstechnik des vollflächigen Vernadelns verbindet die Schichten vollflächig miteinander, so daß ein Aufteilen des Materials auf kleinere Formate ohne weiteres möglich ist. Das neuerungsgemäSe Verbundmaterial benötigt zur KaschierungWhen the substrate is connected to the fleece on the uncoated side by needling, a fleece part with a very low volume weight is formed on the coated side. By using needling as a connection technique, not only are the required threads pulled through the substrate, but the carrier material, which is diffusion-tight in the case of a plastic film as the substrate, is also sufficiently perforated. The connection technique of full-surface needling connects the layers to one another over the entire surface, so that the material can be divided into smaller formats without any problems. The new composite material requires

The thin, healing metal layer can also be made up of several thin layers of different composition.

Der ächicntauiDau aes neuerungsgemauen verounamateriais wiru nun an Hand der Figur noch näher erläutert.The technical properties of the new construction material will now be explained in more detail using the figure.

Die Figur zeigt ein Substrat, beispielsweise eine Kunststofffolie (1), auf dessen einer Oberfläche eine oder meluöre dünne Schichten (2) eines Metalls, einer Metallegierung oder Giner Metallverbindung aufgebracht sind. Auf der gegenüberliegendan Oberfläche ist durch Nadelungstechnik ein Vlies (3) so angeordm/C, daß ein Ttiil der Fäden der Vliesschicht (3) durch das Substrat (1) und durch Schicht (2) hindurchgeführt sind und eine Abstandhalterschicht (4) ausbilden. Diese dünnere Vliesschicht kann in ihrer Abstandhalter- und Pufferwirkung dadurch beeinflußt werden, daß der Nadelverbund zwischen Substrat (1) und Vliesschicht (3) den Erfordernissen entsprechend intensiv gestaltet wird, um die dünne Vliesscnicht (4) auf der Schicht (2) des Substrats (1) auszubilden.The figure shows a substrate, for example a plastic film (1), on one surface of which one or several thin layers (2) of a metal, a metal alloy or a metal compound are applied. On the opposite surface, a fleece (3) is arranged using a needling technique in such a way that a portion of the threads of the fleece layer (3) are passed through the substrate (1) and through layer (2) and form a spacer layer (4). The spacer and buffer effect of this thinner fleece layer can be influenced by designing the needle connection between the substrate (1) and the fleece layer (3) as intensively as required in order to form the thin fleece layer (4) on the layer (2) of the substrate (1).
