Description
Die Erfindung betrifft ein Bezugsmaterial, insbesondere für ein Fahrzeug-Interieurbauteil, gemäß dem Oberbegriff des Anspruches 1. Solche Interieurbauteile umfassen exemplarisch eine Türverkleidung, eine Instrumententafel, Wandteile, Konsolenteile, Lenkrad, Dachhimmel oder dergleichen. Alternativ kann das Bezugsmaterial auch ein Sitzbezug für einen Fahrzeugsitz sein. Die Erfindung betrifft zudem ein Verfahren zur Herstellung eines solchen Bezugsmaterials gemäß dem Anspruch 7.The invention relates to a cover material, in particular for a vehicle interior component, according to the preamble of claim 1. Such interior components include, for example, a door panel, an instrument panel, wall parts, console parts, steering wheel, headliner or the like. Alternatively, the cover material can also be a seat cover for a vehicle seat. The invention also relates to a method for producing such a cover material according to
Ein Fahrzeug- Interieurbauteil kann auf seiner Sichtseite mit einem Bezugsmaterial überzogen sein, das dem Interieurbauteil ein gehobenes ästhetisches Erscheinungsbild sowie eine gesteigerte mechanische Beständigkeit verleiht. Beispielhaft kann das Bezugsmaterial aus Echtleder, Kunstleder, Folien, Holzmaterialien oder Textilien gefertigt sein. Deren Material-Eigenschaften erfüllen im Hinblick auf eine Dehnbarkeit sowie Festigkeit die Anforderungen an ein im Fahrzeug-Interieurbereich eingesetztes Bezugsmaterial.A vehicle interior component can be covered on its visible side with a cover material that gives the interior component a superior aesthetic appearance and increased mechanical durability. For example, the cover material can be made of real leather, imitation leather, foils, wood materials or textiles. Their material properties meet the requirements for a cover material used in vehicle interiors in terms of elasticity and strength.
Speziell die Herstellung eines Echtleder-Bezugsmaterials ist mit aufwendigen Verarbeitungsschritten verbunden, bei dem das Rohleder in einer umfangreichen Prozessabfolge (Weichen, Äschern, Beizen, Pickeln, Gerben, Zurichten) bis zum einsatzfähigen Leder-Bezugsmaterial verarbeitet wird. Diese Verarbeitung ist energieintensiv sowie mit dem Einsatz von Prozesschemikalien verbunden, die eine ökologische Belastung darstellen. Darüber hinaus handelt es sich bei Echtleder um ein tierisches Produkt.In particular, the production of a genuine leather covering material involves complex processing steps in which the rawhide is processed in an extensive process sequence (soaking, liming, staining, pickling, tanning, dressing) into the ready-to-use leather covering material. This processing is energy-intensive and involves the use of process chemicals, which represent an ecological burden. In addition, real leather is an animal product.
Allgemein ist ein alternatives Bio-Bezugsmaterial bekannt, das aus bakteriell synthetisierter Cellulose hergestellt ist. Dessen Material-Eigenschaften genügen jedoch nicht den Anforderungen für den Einsatz im Fahrzeug-Innenraum. Beispielhaft ist aus der

Die Aufgabe der Erfindung besteht darin, ein Bezugsmaterial sowie ein Verfahren zur Herstellung eines solchen Bezugsmaterials bereitzustellen, das im Vergleich zum Stand der Technik mit reduziertem Energieaufwand herstellbar ist und mit reduzierter ökologischer Belastung verbunden ist.The object of the invention is to provide a cover material and a method for producing such a cover material, which can be produced with reduced energy consumption compared to the prior art and is associated with a reduced ecological burden.
Die Aufgabe ist durch die Merkmale des Anspruches 1 oder 7 gelöst. Bevorzugte Weiterbildungen der Erfindung sind in den Unteransprüchen offenbart.The object is solved by the features of
Die Erfindung geht von einem Bezugsmaterial aus, das eine sichtseitige Cellulose-Deckschicht aus bakteriell synthetisierter Cellulose aufweist. Gemäß dem kennzeichnenden Teil des Anspruches 1 ist die Cellulose-Deckschicht Bestandteil eines Mehrlagenaufbaus, bei dem die Cellulose-Deckschicht über eine Klebschicht mit einer Trägerschicht verbunden ist.The invention is based on a cover material that has a cellulose cover layer on the visible side made of bacterially synthesized cellulose. According to the characterizing part of claim 1, the cellulose top layer is part of a multi-layer structure in which the cellulose top layer is connected to a carrier layer via an adhesive layer.
Auf diese Weise wird ein ökologisches Bezugsmaterial als eine Alternative zu einem herkömmlichen Bezugsmaterial aus Leder/Kunstleder zur Verfügung gestellt, das aus einer Oberflächenschicht bakterieller Cellulose, einer zum Beispiel textilen Verstärkung (vorzugsweise ein Gestrick aus Naturfasern) sowie einer verbindenden Klebschicht besteht.In this way, an ecological upholstery material is provided as an alternative to a conventional leather/imitation leather upholstery material, consisting of a surface layer of bacterial cellulose, a e.g. textile reinforcement (preferably a knitted fabric made of natural fibers) and a connecting adhesive layer.
In einer technischen Umsetzung kann die Trägerschicht des Bezugsmaterials eine quer zur Bezugsmaterial-Dickenrichtung erhöhte Reißfähigkeit aufweisen. Auf diese Weise kann die Material-Eigenschaft des Bezugsmaterials im Hinblick auf die Anforderungen beim Einsatz im Fahrzeug-Interieurbereich erhöht werden. Insbesondere wird mit der Trägerschicht die automobile Anforderung hinsichtlich einer Weiterreißkraft (DIN EN ISO 377-1) erhöht.In a technical implementation, the carrier layer of the cover material can have increased tearability transversely to the cover material thickness direction. In this way, the material properties of the cover material can be increased with regard to the requirements when used in vehicle interiors. In particular, the automotive requirement with regard to tear propagation strength (DIN EN ISO 377-1) is increased with the carrier layer.
Die Trägerschicht kann bevorzugt ein Faserhalbzeug, etwa ein Gestrick, ein Gewebe, ein Gewirk oder ein Vlies sein. Das Faserhalbzeug kann bei der Herstellung des Bezugsmaterials in einem Trockenzustand, das heißt ohne Binder, bereitgestellt sein.The carrier layer can preferably be a semi-finished fiber product, such as a knitted fabric, a woven fabric, a knitted fabric or a fleece. During the manufacture of the cover material, the semi-finished fiber product can be provided in a dry state, ie without a binder.
In einer ersten Ausführungsvariante kann das Faserhalbzeug aus Naturfasern hergestellt sein, insbesondere aus Leinen, Baumwolle, Ramie, Tecel. In einer alternativen Ausführungsvariante kann das Faserhalbzeug aus synthetischen Fasern hergestellt sein. Insbesondere aus Polyester, Nylon oder dergleichen. Zudem kann das Faserhalbzeug eine Fasermischung aus synthetischen Fasern sowie Naturfasern aufweisen.In a first embodiment variant, the semi-finished fiber product can be made from natural fibers, in particular from linen, cotton, ramie, tecel. In an alternative embodiment, the semi-finished fiber product can be made of synthetic fibers. In particular, made of polyester, nylon or the like. In addition, the semi-finished fiber product can have a fiber mixture of synthetic fibers and natural fibers.
Im Hinblick auf die Material-Anforderungen im Fahrzeug-Interieurbereich ist es bevorzugt, wenn die Klebschicht aus einem elastisch nachgiebigen Material, insbesondere Schaummaterial, realisiert ist, etwa ein PU-Schaum. Ein solches elastisch nachgiebiges Schaummaterial ist im Hinblick auf eine gesteigerte Haftung der Trägerschicht an der Cellulose-Deckschicht sowie im Hinblick auf eine verbesserte Haptik von Vorteil.With regard to the material requirements in the vehicle interior area, it is preferred if the adhesive layer is made of an elastically yielding material, in particular foam material, such as PU foam. Such an elastically flexible foam material is advantageous with regard to increased adhesion of the carrier layer to the cellulose cover layer and with regard to improved haptics.
Ein Verfahren zur Herstellung des erfindungsgemäßen Bezugsmaterials kann die folgende Prozesskette aufweisen: So kann in einem Bereitstellungsschritt zunächst ein Vorformling aus einer flächigen Roh-Celluloseschicht bereitgestellt werden. Die flächige Roh-Celluloseschicht kann in einem anschließenden Kalandrierschritt bearbeitet werden, und zwar unter Bildung der Cellulose-Deckschicht. In einem nachfolgenden Endbearbeitungsschritt kann die Sichtseite der Cellulose-Deckschicht in einem Pulver- oder Sprühverfahren mit Farblack beschichtet werden. Anschließend erfolgt ein Fügeprozess, bei dem die Cellulose-Deckschicht unter Zwischenlage der Klebschicht mit der Trägerschicht verbunden wird.A method for producing the cover material according to the invention can have the following process chain: In a preparation step, a preform made of a flat layer of raw cellulose can first be provided. The flat raw cellulose layer can be processed in a subsequent calendering step, specifically with the formation of the cellulose cover layer. In a subsequent finishing step, the visible side of the cellulose top layer can be coated with colored lacquer in a powder or spray process. This is followed by a joining process in which the cellulose top layer is bonded to the carrier layer with the adhesive layer in between.
Bevorzugt kann der Fügeschritt in einer Schäumungsanlage durchgeführt werden. Hierzu werden die Cellulose-Deckschicht und die Trägerschicht als Einlegerteile in eine Werkzeugkavität der Schäumungsanlage eingelegt, und zwar mit Abstand zueinander. Anschließend erfolgt ein Schäumungsprozess, bei dem die Cellulose-Deckschicht und die Trägerschicht mit der als Schaummaterial realisierten Klebschicht hinterschäumt werden.The joining step can preferably be carried out in a foaming plant. For this purpose, the cellulose cover layer and the carrier layer are placed as insert parts in a mold cavity of the foaming plant, specifically at a distance from one another. This is followed by a foaming process in which the cellulose top layer and the carrier layer are back-foamed with the adhesive layer realized as foam material.

Bei der Klebschicht muss es sich nicht zwingend um eine Schaumschicht handeln. Bei einer späteren Verarbeitung würde höchstwahrscheinlich eine zusätzliche Schaumkaschierung (vergleiche eine herkömmliche Weiterverarbeitung von Leder oder Kunstleder zum finalen Bauteil) folgen.The adhesive layer does not necessarily have to be a foam layer. If processed later, an additional foam lamination would most likely follow (compare to conventional further processing of leather or artificial leather to the final component).
Das Bezugsmaterial 1 kann eine Schichtdicke s von beispielhaft 1 bis 7 mm aufweisen und ist für den Einsatz im Fahrzeug-Interieurbereich ausgelegt. Beispielhaft kann das Bezugsmaterial 1 ein Innenverkleidungsteil überziehen, etwa eine Instrumententafel, eine Türverkleidung, Wandteile, Konsolenteile, Dachhimmel oder dergleichen. Alternativ dazu kann das Bezugsmaterial 1 auch als Sitzbezug für Fahrzeugsitze eingesetzt werden.The cover material 1 can have a layer thickness s of 1 to 7 mm, for example, and is designed for use in the vehicle interior. For example, the cover material 1 can cover an interior trim part, such as an instrument panel, a door panel, wall parts, console parts, headliner or the like. As an alternative to this, the cover material 1 can also be used as a seat cover for vehicle seats.
