Description

Die Erfindung betrifft ein Isoliermaterial, das einseitig mit einer Trägerbahn versehen ist und aus einer Vielzahl von Fasern aus Schafwolle besteht.The invention relates to an insulating material which is provided on one side with a carrier web and consists of a plurality of sheep wool fibers.

Bereits in der DE-PS 12 217 ist ein Isoliermaterial beschrieben, das aus zwei Lagen zähen und starken Papiers besteht, zwischen denen Watte aus Wolle eingeklebt ist.Already in DE-PS 12 217 an insulating material is described, which consists of two layers of tough and strong paper, between which cotton wool is glued.

Schafwolle hat sich als hervorragendes Isoliermaterial erwiesen, da ein aus Schafwolle hergestelltes Isoliermaterial eine niedrige Wärmeleitzahl und damit eine gute thermische Dämmung aufweist. Darüber hinaus hat Schafwolle ein sehr gutes Brandverhalten, da sie im Entzündungsfall nur glimmt und selbsttätig erlischt. Die Schafwolle ist im Stande, auch größere Mengen Feuchtigkeit aufzunehmen und behält dabei ihre guten Wärmedämm-Eigenschaften. Darüber hinaus belastet Schafwolle im Falle der Entsorgung die Umwelt nicht, da sie vollständig biologisch abbaubar und wiederverwertbar ist. Als Naturprodukt fällt Schafwolle in großer Menge an und bedarf nur geringer Energiemengen zum Aufbereiten als Isoliermaterial.Sheep wool has proven to be an excellent insulating material, since an insulating material made from sheep wool has a low thermal conductivity and therefore good thermal insulation. In addition, sheep's wool has very good fire behavior, since it only glows in the event of ignition and goes out automatically. The sheep's wool is also able to absorb large amounts of moisture while maintaining its good thermal insulation properties. In addition, sheep's wool does not pollute the environment when it is disposed of, as it is completely biodegradable and recyclable. As a natural product, sheep's wool is produced in large quantities and requires only a small amount of energy to process it as an insulating material.

Der Erfindung liegt die Aufgabe zugrunde, ein Isoliermaterial zu schaffen, das unter Verwendung von Schafwolle hergestellt ist und dabei möglichst wenig Fremdstoffe benötigt.The invention has for its object to provide an insulating material that is made using sheep's wool and requires as little foreign matter as possible.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Fasern durch Eindrücken von Nadeln (vernadeln) wenigstens geringfügig miteinander verbunden sind.This object is achieved in that the fibers are at least slightly connected to each other by pushing in needles.

Dadurch wird eine sehr gute Verflechtung der Schafwollefasern untereinander erreicht, ohne daß Kleber oder dergleichen Hilfsmittel notwendig wären um einen ausreichenden Zusammenhalt der Wollefasern zu erreichen.This results in a very good interweaving of the sheep's wool fibers with one another without the need for glue or the like to achieve sufficient cohesion of the wool fibers.

Eine so hergestellte Isoliermatte kann je nach dem vorgesehenen Einsatzzweck mit einem sehr niedrigen Raumgewicht ausgestattet sein.An insulating mat produced in this way can be equipped with a very low density depending on the intended use.

Sehr vorteilhaft ist es auch, wenn erfindungsgemäß die Trägerbahn ebenfalls aus Schafwolle-Fasern hergestellt und beim Vernadeln vorzugsweise höher verdichtet ist als die eigentliche Isolierbahn und wenn die beiden Bahnen durch das die eigentliche Isolierbahn verfestigende Vernadeln miteinander verbunden sind.It is also very advantageous if, according to the invention, the carrier web is also made of sheep's wool fibers and is preferably compressed to a higher degree than the actual insulating web when needling, and if the two webs are connected to one another by needling that solidifies the actual insulating web.

Durch die höhere Verdichtung der Trägerbahn erhält diese auch eine höhere Reißfestigkeit und kann ihre Funktion als Trägerbahn ohne weitere Hilfsmittel wahrnehmen. Auch für die Verbindung von Trägerbahn und Isolierbahn ist bei dieser Ausgestaltung kein weiteres Verbindungsmittel oder Verbindungsmaterial notwendig, so daß das Isoliermaterial völlig frei von Fremdstoffen ist.Due to the higher compression of the carrier web, it also has a higher tear resistance and can perform its function as a carrier web without any additional aids. Also for the connection of the carrier sheet and the insulating sheet, no further connecting means or connecting material is necessary in this embodiment, so that the insulating material is completely free of foreign substances.

Eine weitere vorteilhafte Ausgestaltung der Erfindung liegt darin, daß die Trägerbahn an ihren beiden Längsrändern wenigstens geringfügig über die eigentliche Isolierbahn vorsteht.A further advantageous embodiment of the invention lies in the fact that the carrier web protrudes at least slightly beyond the actual insulating web at its two longitudinal edges.

Mit den beiden über die eigentliche Isolierbahn vorstehenden Trägerbahnstreifen kann das Isoliermaterial befestigt werden. Dieses ist vorteilhaft, wenn das Isoliermaterial z.B. für die Isolierung von Dachschrägen oder dergleichen Räumen, bei denen das Isoliermaterial keine Unterstützung von unten erfährt und es aufgrund der Weichheit des Materials Probleme geben kann, verwendet wird. Mit den beiden vorstehenden Trägerbahnstreifen kann das Isoliermaterial an den Sparren eines Daches befestigt werden und erfährt so einen ausgezeichneten Halt. Gleichzeitig trägt die Trägerbahn aber auch zur Isolierung bei und unterstützt die eigentliche Isolierbahn ganz wesentlich.The insulating material can be fastened with the two carrier strip strips projecting over the actual insulating sheet. This is advantageous if the insulating material e.g. for the insulation of sloping ceilings or similar rooms where the insulating material is not supported from below and where there may be problems due to the softness of the material. With the two carrier strip strips above, the insulating material can be attached to the rafters of a roof and thus has an excellent hold. At the same time, the carrier sheet also contributes to the insulation and supports the actual insulating sheet significantly.

Ebenfalls sehr vorteilhaft ist es, wenn erfindungsgemäß die eigentliche Isolierbahn aus mehreren dünneren Teilbahnen aufgebaut ist, welche miteinander vernadelt sind.It is also very advantageous if, according to the invention, the actual insulating sheet is constructed from a plurality of thinner partial sheets which are needled together.

Damit ist es möglich, das Isoliermaterial auch in großen Dicken herzustellen, wobei keine unnötig langen Nadeln zum Vernadeln eingesetzt werden müssen. Darüber hinaus ist es dabei möglich, die einzelnen Lagen unterschiedlich stark zu vernadeln, um so das Isoliermaterial an die unterschiedlichsten Isolierbedingungen anpassen zu können.This makes it possible to produce the insulating material even in large thicknesses, without needlessly long needles being used for needling. In addition, it is possible to needle the individual layers to different degrees, so that the insulation material can be adapted to the most varied of insulation conditions.

Sehr vorteilhaft ist es auch, wenn die Trägerbahn zusätzlich mit einer weiteren, auf der von der Isolierbahn abgekehrten Seite angebrachten Abdeckbahn versehen ist.It is also very advantageous if the carrier web is additionally provided with a further covering web attached to the side facing away from the insulating web.

Diese zusätzliche Abdeckbahn kann sowohl die mechanische Festigkeit der Trägerbahn erhöhen, ohne ihre Isoliereigenschaften zu beeinträchtigen, sie kann aber auch als zusätzliche Dampfsperre ausgebildet sein.This additional cover sheet can both increase the mechanical strength of the carrier sheet without impairing its insulating properties, but it can also be designed as an additional vapor barrier.

Als sehr vorteilhaft hat es sich erwiesen, wenn erfindungsgemäß die Abdeckbahn aus Papier od. dgl. besteht.It has proven to be very advantageous if, according to the invention, the cover sheet consists of paper or the like.

Papier in der entsprechenden Ausgestaltung ergibt eine hohe zusätzliche Festigkeit und kann gleichzeitig als Dampfsperre ausgebildet sein.Paper in the corresponding configuration results in a high additional strength and can also be designed as a vapor barrier.

Mit 1 ist in Fig.1 eine Isoliermatte bezeichnet, die aus einer Isolierbahn 2 und einer Trägerbahn 3 aufgebaut ist. Sowohl die Isolierbahn 2 als auch die Trägerbahn 3 sind aus lose aufeinandergelegten Schafwollefasern aufgebaut, die miteinander vernadelt sind. Dabei ist die Trägerbahn 3 verhältnismäßig stark vernadelt, wodurch sie eine günstige Reißfestigkeit aufweist und der Isoliermatte die nötige Verarbeitungsfestigkeit verleiht. Die Isolierbahn ist dagegen nur geringfügig vernadelt, so daß die Fasern zwar zusammenhalten aber nicht unnötig zusammengepreßt sind. Dabei ist es möglich, die Fasern beim Auflegen zu verwirbeln, um den Zusammenhalt noch weiter zu verbessern. Zum Vernadeln der Isolierbahn 2 wird diese auf die Trägerbahn aufgelegt und von oben vernadelt, wobei infolge von durchgreifenden Nadeln auch gleichzeitig eine Verbindung der beiden Bahnen geschaffen wird.1 in FIG. 1 denotes an insulating mat which is constructed from an insulating sheet 2 and a carrier sheet 3. Both the insulating sheet 2 and the carrier sheet 3 are made up of loosely laid sheep's wool fibers, which are needled together. The carrier web 3 is needled comparatively strongly, as a result of which it has a favorable tensile strength and gives the insulating mat the necessary processing strength. The insulating sheet, on the other hand, is only slightly needled, so that the fibers hold together but are not unnecessarily compressed. It is possible to swirl the fibers when laying them on to further improve cohesion. For needling the insulating sheet 2, it is placed on the carrier sheet and needled from above, whereby a connection of the two sheets is created at the same time as a result of penetrating needles.

Beim Ausführungsbeispiel nach Fig.2 ist eine Isoliermatte 21 dargestellt, die aus drei Lagen aufgebaut ist, nämlich einer Isolierlage 22, einer Trägerlage 23 und einer zwischen beiden angeordneten weiteren Lage 24. Die Isolierlage 22 und die Trägerlage 23 entsprechen weitgehend den Bahnen 2 und 3 nach Fig.1. Die weitere Lage 24 ist geringfügig fester genadelt als die Isolierlage 22 und wird als erste auf die Trägerlage aufgebracht und mit dieser beim Nadeln verbunden. Die Isolierlage und die weitere Lage können jede beliebige, durch Vernadeln erzeugte Festigkeit aufweisen und jeweils aus beliebig vielen Einzellagen aufgebaut sein. Die Verbindung jeder Lage mit der darunterliegenden erfolgt jeweils wieder beim Vernadeln.In the exemplary embodiment according to FIG. 2, an insulating mat 21 is shown which is composed of three layers, namely an insulating layer 22, a carrier layer 23 and a further layer 24 arranged between the two. The insulating layer 22 and the carrier layer 23 largely correspond to the tracks 2 and 3 according to Fig. 1. The further layer 24 is needled slightly firmer than the insulating layer 22 and is applied first to the carrier layer and connected to it when needling. The insulating layer and the further layer can have any strength generated by needling and can each be constructed from any number of individual layers. The connection of each layer with the one underneath takes place again when needling.

Bei dem in Fig.3 dargestellten Ausführungsbeispiel ist wieder eine Isolierbahn 32 und eine Trägerbahn 33 vorgesehen, die wie vorher beschrieben hergestellt und miteinander verbunden sind. An der von der Isolierbahn 32 abgekehrten Seite der Trägerbahn 33 ist eine einseitig gewellte Wellpappebahn 35 aufgebracht, die an ihrer glatten Außenseite eine Aluminiumfolie 36 trägt. Bei dieser Ausgestaltung dienen die Wellpappebahn 35 und die Aluminiumfolie 36 zur weiteren Versteifung und als Dampfsperre.In the exemplary embodiment shown in FIG. 3, an insulating sheet 32 and a carrier sheet 33 are again provided, which are produced and connected to one another as previously described. On the side of the carrier web 33 facing away from the insulating web 32, a corrugated cardboard web 35 corrugated on one side is applied, which carries an aluminum foil 36 on its smooth outside. At this Design the corrugated cardboard web 35 and the aluminum foil 36 serve for further stiffening and as a vapor barrier.

Das in Fig.4 gezeigte Ausführungsbeispiel hat eine Isolierbahn 42 und eine Trägerbahn 43, die wieder durch vernadeln hergestellt und verbunden sind. Die Trägerbahn 43 ist auf ihrer von der Isolierbahn 42 abgekehrten Seite mit einer Aluminiumfolie 46 abgedeckt, die als Dampfsperre dient.The exemplary embodiment shown in FIG. 4 has an insulating sheet 42 and a carrier sheet 43, which are again produced and connected by needling. The carrier web 43 is covered on its side facing away from the insulating web 42 with an aluminum foil 46 which serves as a vapor barrier.

In Fig.5 ist ein Ausführungsbeispiel eines Isoliermaterials 51 dargestellt, das aus einer Isolierbahn 52 und einer Trägerbahn 53 besteht. Die beiden Bahnen 52,53 sind aus Schafwollefasern hergestellt, die durch Vernadeln zu einem innigen Verband zusammengefügt sind. Dabei ist die Trägerbahn höher verdichtet als die Isolierbahn, wodurch sie eine größere Festigkeit aufweist. Auch die Verbindung zwischen der Trägerbahn und der Isolierbahn ist durch dieses Vernadeln herbeigeführt. Die Trägerbahn 53 steht an beiden Längsseiten über die Isolierbahn 52 vor, wodurch Streifen 54 bzw. 55 entstanden sind, die zum Annageln des Isoliermaterials, beispielsweise an Dachsparren, dienen.5 shows an embodiment of an insulating material 51, which consists of an insulating sheet 52 and a carrier sheet 53. The two webs 52, 53 are made from sheep's wool fibers, which are joined together to form an intimate association by needling. The carrier sheet is more densely compressed than the insulating sheet, which makes it stronger. The connection between the carrier sheet and the insulating sheet is also brought about by this needling. The carrier sheet 53 protrudes on both longitudinal sides over the insulating sheet 52, whereby strips 54 and 55 are formed which serve to nail the insulating material, for example to rafters.

Beim Ausführungsbeispiel nach Fig.6 ist eine Trägerbahn 63, auf ihrer von einer Isolierbahn 62 abgewandten Seite, mit einer Abdeckbahn 66 versehen, die aus Papier hergestellt ist. Es kann sich dabei um einfaches Kraftpapier handeln, es ist aber auch möglich, imprägniertes Papier zu verwenden, das dann auch als Dampfsperre dienen kann. Die Trägerbahn 63 steht auch bei diesem Ausführungsbeispiel an beiden Längsseiten über die Isolierbahn 62 vor, wodurch Streifen 64 bzw. 65 entstehen.In the embodiment according to FIG. 6, a carrier web 63, on its side facing away from an insulating web 62, is provided with a cover web 66 which is made of paper. It can be simple kraft paper, but it is also possible to use impregnated paper, which can then also serve as a vapor barrier. In this exemplary embodiment as well, the carrier web 63 projects over the insulating web 62 on both longitudinal sides, as a result of which strips 64 and 65 are formed.

Das Ausführungsbeispiel gemäß Fig.7 zeigt ein Isoliermaterial aus einer Isolierbahn 72, einer Trägerbahn 73 und einer Abdeckbahn 77, welche mehrschichtig aufgebaut ist. Dabei können je nach Einsatzzweck für die einzelnen Schichten der Abdeckbahn 77 unterschiedliche Materialien verwendet werden. So ist beispielsweise der Einsatz von Aluminiumfolie oder Kunststoffolie denkbar, beides beispielsweise in Kombination mit einer dünnen Papierlage. Durch die über die Isolierbahn 72 überstehenden Trägerbahn 73 entstehen auch bei diesem Ausführungsbeispiel Streifen 74 bzw. 75 zum Annageln des Isoliermaterials.The exemplary embodiment according to FIG. 7 shows an insulating material composed of an insulating sheet 72, a carrier sheet 73 and a cover sheet 77, which is constructed in multiple layers. Depending on the application, this can be done for the individual Layers of cover sheet 77 different materials can be used. For example, the use of aluminum foil or plastic foil is conceivable, both in combination with a thin paper layer, for example. The carrier web 73 projecting beyond the insulating web 72 also produces strips 74 and 75 for nailing the insulating material in this exemplary embodiment.
