WO 2015/074870 A1 describes the use of a two-layer carpet with a usable velor surface in a motor vehicle. US 2008/220200 A1 describes a tufted carpet made of PET fibers for use in the automotive sector. DE 102 25 072 CI discloses a floor covering for motor vehicles with a tufted velor carpet layer, comprising a tuft carrier carrying tufts, on the underside of which there are longitudinal rows of tufts with backstitching in a zigzag pattern.
Gemäß DE 101 34 934 Al werden Flachnadelbahnen beschrieben, die aus Natur- und / oder Chemiefasern bestehen und 200-1600 g/m2 wiegen. Mindestens eine der Hauptflächen weist eine Beschichtung in Form eines Musters auf. Das Grundmaterial kann Pflanzenfasern wie Baumwolle, Ka pok, Hanf, Jute, Sisal und Kokos umfassen. Das Muster ist über die ge samte Hauptfläche oder einen Teil davon verteilt und besteht aus Nop pen, Linien und Kreisen. According to DE 101 34 934 A1, flat needle webs are described which consist of natural and / or chemical fibers and weigh 200-1600 g / m 2 . At least one of the main surfaces has a coating in the form of a pattern. The base material can include vegetable fibers such as cotton, ka pok, hemp, jute, sisal and coconut. The pattern is distributed over the entire main surface or part of it and consists of knobs, lines and circles.
US 2018/ 0142387 Al beschreibt ein Verfahren zur Bildung eines Vlies verbundes, das mit der Bildung eines ersten Vlieses aus mehreren Pri märfasern und gegebenenfalls Bindefasern besteht. Eine zweite Vlies schicht wird aus einer Vielzahl von Füllfasern und Bindefasern gebildet. Eine thermoplastische Elastomerfolie wird zwischen die beiden Vlies schichten gelegt, wobei die Folie ein thermoplastisches Elastomer mit ei ner Reißdehnung von mehr als 300% und einem maximalen Erwei chungspunkt (thermomechanischer Analyseendpunkt) zwischen 150 ° C und 200 ° C enthält (geprüft nach ASTM E2347-04). Die Schichten wer den zusammengenadelt, wodurch mehrere Löcher in der thermoplasti schen Elastomerschicht erzeugt werden und ein Teil der Primärfasern von der ersten Vliesschicht in die zweite Vliesschicht bewegt wird. Die gen adelten gestapelten Schichten werden erwärmt, um die mittlere Größe der Löcher in der thermoplastischen Elastomerfolie zu ändern, die den Vliesverbundstoff bildet. US 2018/0142387 Al describes a method for forming a nonwoven composite which consists of several primary fibers and possibly binding fibers with the formation of a first nonwoven. A second nonwoven layer is formed from a large number of filler fibers and binding fibers. A thermoplastic elastomer film is placed between the two fleece layers, the film containing a thermoplastic elastomer with an elongation at break of more than 300% and a maximum softening point (thermomechanical analysis end point) between 150 ° C and 200 ° C (tested according to ASTM E2347- 04). The layers are needled together, creating several holes in the thermoplastic's elastomer layer and moving part of the primary fibers from the first nonwoven layer into the second nonwoven layer. The needle-punched stacked layers are heated to the middle size of the holes in the thermoplastic elastomer sheet that forms the nonwoven composite.
In US2011/0186381 Al ist die Aufgabe der Erfindung, ein Schallabsorp tionsmaterial mit einem geringen Gewicht und einem ausgezeichneten Schallabsorptionsvermögen sowie ein Schallabsorptionsmaterial bereit zustellen, das aus einer Faserschicht aus Fasern besteht, die mindestens 50 Massen-% einer porösen Faser mit vielen winzigen Poren enthält , wobei sich die winzigen Poren auf die Oberfläche der porösen Faser öffnen und einen Luftströmungswiderstand im Bereich zwischen 0,05 und 3,0 kPa s/m aufweisen. Die poröse Faser mit vielen winzigen Poren, von de nen sich jede auf die Oberfläche der porösen Faser öffnet, hat eine Luft durchlässigkeit und somit eine Schallabsorptionseigenschaft an sich. Wei tere schallabsorbierende Eigenschaften, die durch die Zwischenräume zwischen den porösen Fasern erzeugt werden, führen dazu, dass die Folie zu einem schallabsorbierenden Material mit einer extrem hohen Schallabsorptionseffizienz wird. In US2011 / 0186381 A1 the object of the invention is to provide a sound absorption material with a low weight and excellent sound absorption capacity and a sound absorption material which consists of a fiber layer of fibers which contains at least 50% by mass of a porous fiber with many tiny pores wherein the tiny pores open onto the surface of the porous fiber and have an air flow resistance in the range between 0.05 and 3.0 kPa s / m. The porous fiber having many minute pores each of which opens onto the surface of the porous fiber has air permeability and thus sound absorption property in itself. Further sound-absorbing properties, which are generated by the spaces between the porous fibers, mean that the film becomes a sound-absorbing material with an extremely high sound-absorbing efficiency.
Gemäß EP1190647 A2 umfasst eine Schutzschicht ein flexibles Trä gersubstrat für eine flache Oberfläche und mehrere Elemente für eine flache Oberfläche, die über die Oberfläche des Substrats verteilt sind und eine größere Schneidfestigkeit als das Substrat. Die ebenen Flächenele mente sind versetzt zueinander angeordnet, so dass sich in einer Projek tion von Grenzlinien, die zwischen zwei benachbarten Elementen verlau fen, weitere Elemente befinden, um die Projektion der Grenzlinien über die Oberfläche des Substrats aufzubrechen. Alle ebenen Flächenelemente können die gleiche Form haben und ohne Überlappung nebeneinander angeordnet werden. Bei Tufting-Teppichen werden im Stand der Technik insbesondere PA6.6, PA6, PP, rPA und PET, rPET sowie die bio-basierenden Polyamide (PA 5.10; PA 6.10) oder Wolle als Garn-/Fasermaterial eingesetzt. Im Bereich der Velours- und Flachnadelvlies-Teppichen finden vorwiegend PET, PET/PP, PP, PA/PET und rPET als Garn-/Fasermaterial Verwendung. Der Tuftingträger bei den Tufting-Qualitäten besteht zumeist aus PET/PP, PET/coPET oder PET/PA. According to EP1190647 A2, a protective layer comprises a flexible carrier substrate for a flat surface and several elements for a flat surface, which are distributed over the surface of the substrate and have a greater cutting resistance than the substrate. The flat surface elements are arranged offset to one another, so that in a projection of boundary lines that run between two adjacent elements, further elements are located in order to break up the projection of the boundary lines over the surface of the substrate. All flat surface elements can have the same shape and be arranged next to one another without overlapping. In the prior art, tufted carpets in particular use PA6.6, PA6, PP, rPA and PET, rPET and the bio-based polyamides (PA 5.10; PA 6.10) or wool as yarn / fiber material. In the area of velor and flat needle felt carpets, PET, PET / PP, PP, PA / PET and rPET are mainly used as yarn / fiber material. The tufting backing for the tufting qualities mostly consists of PET / PP, PET / coPET or PET / PA.
Die hier angewandten Fasereinbindungen umfassen bei Tufting-Teppich vorwiegend EVA sowie PE und bei den Velours- und Flachnadelvlies-Tep- pichen SBR-Latex oder Acrylat. Weiterhin werden bei Velours- und Flach nadelvlies-Teppichen Folien, Vliese, Klebstoffe (hot melts), thermoplasti sche Kunststoffe (vorwiegend PE) sowie das in EP 1 598 476 Bl beschrie bene Thermo-Bonding-Verfahren eingesetzt. Des Weiteren finden zuneh mend Bindefasern, EVA oder thermoplastische Dispersionen Anwendung. The fiber bindings used here mainly comprise EVA and PE for tufted carpets and SBR latex or acrylate for velor and flat needle felt carpets. Furthermore, foils, fleeces, adhesives (hot melts), thermoplastic plastics (predominantly PE) and the thermo-bonding process described in EP 1 598 476 B1 are used in velor and flat needle-punched carpets. Binding fibers, EVA or thermoplastic dispersions are also increasingly used.
Unter der Nutzfläche befinden sich Klebeschichten, Akustik-/Verstei- fungs-Vliese, Dicht- und Schwerfolien sowie Kontakt-/Folienvliese. Die Beschichtung, meist als Klebeschicht für Untervliese, aber auch zur Ver steifung, umfasst vorwiegend PE oder PP. Adhesive layers, acoustic / reinforcement fleeces, sealing and heavy foils as well as contact / foil fleeces are located under the usable area. The coating, mostly as an adhesive layer for sub-fleece, but also for stiffening, mainly comprises PE or PP.
Die Unterschichten, wie Akustik- und/oder Versteifungsvliese, bestehen in der Regel aus PET- und Mischfaservliesen, oftmals mit einem BiCo- Faseranteil. Als Dicht- oder Dämmfolien finden PE/PA- und PE/PA/PE- Folien sowie Folienvliese PE/PA/PE+PET Anwendung. Je nach akustischen Anforderungen werden auch sogenannte Schwerfolien partiell oder voll flächig als Dämmfolien eingesetzt. Zwischen Oberware (Nutzschicht plus Unterschichten) und Karosseriebo den befindet sich üblicherweise eine Isolationsschicht, die insbesondere aus PUR-Schaum oder Vliesstrukturen (Vliese oder Faser-Flock- (FIMP)Verbunde) gebildet sein kann. Wird ein Schaum eingesetzt, ist die ser mit der Oberware fest verbunden (angeschäumt). Vlies-/Faser- Flockstrukturen können mit der Oberware ebenfalls fest verbunden sein, wobei diese dann in der Regel verklebt sind. Es findet aber auch ein reines Übereinanderlegen ohne feste Verbindung Anwendung. The lower layers, such as acoustic and / or stiffening fleece, usually consist of PET and mixed fiber fleeces, often with a BiCo fiber content. PE / PA and PE / PA / PE foils as well as foil fleece PE / PA / PE + PET are used as sealing or insulating foils. Depending on the acoustic requirements, so-called heavy-duty foils are used partially or fully as insulating foils. Between the upper material (wear layer plus lower layers) and the body floor there is usually an insulation layer that can be formed in particular from PUR foam or nonwoven structures (nonwovens or fiber-flock (FIMP) composites). If a foam is used, this is firmly connected to the upper fabric (foamed). Fleece / fiber flock structures can also be firmly connected to the outer fabric, whereby these are then usually glued. However, pure laying on top of one another without a fixed connection is also used.
Insbesondere bei VANs, SUVs, Pickups und leichten Nutzfahrzeugen sind im Stand der Technik auch Gummi, PUR-RIM, PVC und zunehmend TPO als Nutzfläche im Einsatz. So offenbart beispielsweise DE 10 2008 046 915 Al ein mehrschichtiges, insbesondere tiefgezogenes Formteil, insbe sondere einen Bodenbelag zur Auskleidung eines Fahrzeugbodens, mit einer TPO-Folie als Deckschicht, die auf einer Trägerschicht fest angeord net ist, wobei die TPO-Folie als Trägerschicht eine Fasermatte, insbeson dere eine Polymerfasermatte, aufweist. In the prior art, rubber, PUR-RIM, PVC and increasingly TPO are also used as usable surfaces, particularly in VANs, SUVs, pickups and light commercial vehicles. For example, DE 10 2008 046 915 A1 discloses a multilayer, in particular deep-drawn molded part, in particular a floor covering for lining a vehicle floor, with a TPO film as the cover layer, which is firmly angeord net on a carrier layer, the TPO film as a carrier layer Fiber mat, in particular a polymer fiber mat, has.
Die zuvor genannten im Stand der Technik beschriebenen Bodenverklei- dungs-, Gepäckraumverkleidungs- und Ladeboden-Nutzflächen, weisen keine besonderen, über die heute von den OEM ' s spezifizierten hinaus gehenden Gebrauchswert-Eigenschaften auf, insbesondere im Hinblick auf das Verschleiß- und Reinigungsverhalten. The Bodenverklei- described in the prior art aforementioned Droppings, Gepäckraumverkleidungs- and load floor-land, have no particular, on the day of the OEM's specified beyond use-value properties, particularly in terms of wear and cleaning properties.
In der WO 2018/219844 Al wird eine Bodenverkleidung mit geflockter Nutzfläche beschrieben, wobei diese insbesondere ein verbessertes Ver schleißverhalten aufweist. Aus WO 2018/170115 Al ist ein dekoratives Vliesstofflaminat bekannt. DE 10 2017 103 943 Al offenbart ein Verklei dungsteil für ein Kraftfahrzeug mit bedruckten thermoplastische Folien, deren Trägerschichten Faservliesschichten und/oder Schwerschichten sind. In WO 2018/219844 A1, a floor covering with a flocked usable area is described, which in particular has improved wear behavior. From WO 2018/170115 Al is a decorative Known nonwoven laminate. DE 10 2017 103 943 A1 discloses a cladding part for a motor vehicle with printed thermoplastic films, the carrier layers of which are fiber fleece layers and / or heavy layers.
Darüber hinaus sind textile Flächengebilde als Nutzfläche in der Möbelin dustrie bekannt, bei denen keramische Partikel und/oder Glaspartikel und/oder metallische Partikel als Füllstoffe von plättchenförmigen Be schichtungselementen Anwendung finden. So offenbart beispielsweise DE 10 2014 110 611 Al ein textiles Flächengebilde mit einem flexiblen Sub strat, auf das eine Vielzahl von plättchenförmigen Elementen aus einem abriebfesten und steiferen Material als das Substrat aufgebracht sind. In addition, textile fabrics are known as a usable surface in the furniture industry in which ceramic particles and / or glass particles and / or metallic particles are used as fillers of platelet-shaped coating elements. For example, DE 10 2014 110 611 A1 discloses a flat textile structure with a flexible substrate to which a large number of platelet-shaped elements made of an abrasion-resistant and stiffer material than the substrate are applied.
Aus DE 20 2016 006 953 Ul ist ein flexibles Flächenprodukt, insbeson dere aus Textilien, Kunstleder oder Netzstoffen mit einer in definierten Bereichen aufgebrachten Beschichtung, die eine hohe Dehn- oder Stauchfähigkeit aufweist bekannt. DE 20 2016 006 953 U1 discloses a flexible flat product, in particular made of textiles, synthetic leather or mesh materials with a coating applied in defined areas which has a high degree of elasticity or compressibility.
Dieser Stand der Technik betrifft jedoch zweidimensionale Verformungen, mit geringem Ausziehverhalten. Die Anforderungen, die im Automobilbe reich an Bodenverkleidungen, Gepäckraumverkleidungen und Ladeboden vorzufinden sind, stehen hier nicht im Fokus. Grundsätzlich sei erwähnt, dass die in der Automobilindustrie spezifizierten Eigenschaften, unter an derem, hinsichtlich Akustik, Trittfestigkeit, mechanischem Verschleiß, Biegesteifigkeit, Reinigungsfähigkeit, Medienbeständigkeit, Verfor mungsverhalten, Klima- und Wärmealterungsbeständigkeit im beschrie benen Stand der Technik keine Beachtung finden. Gegenüber diesem Stand der Technik liegt der vorliegenden Erfindung daher die Aufgabe zugrunde, eine verformungsgerechte und verfor mungsstabile Oberware (Nutzschicht plus Unterschichten) für ein Verklei dungsteil eines Kraftfahrzeugs mit verbesserten Gebrauchswerteigen schaften bereitzustellen, die insbesondere eine verschleiß- und reini gungsoptimierten Nutzfläche umfasst und den spezifizierten Anforderun gen der Automobilindustrie gerecht wird. However, this prior art relates to two-dimensional deformations with low pull-out behavior. The requirements that are to be found in the automotive sector in terms of floor panels, luggage compartment panels and loading floors are not in focus here. Basically, it should be mentioned that the properties specified in the automotive industry, including with regard to acoustics, impact resistance, mechanical wear, flexural rigidity, cleanability, media resistance, deformation behavior, climatic and thermal aging resistance are not considered in the state of the art described. Compared to this prior art, the present invention is therefore based on the object of providing a deformation-compatible and deformation-stable upper material (wear layer plus underlayers) for a cladding part of a motor vehicle with improved utility properties, which in particular comprises a wear and cleaning-optimized usable area and the specified Meets the requirements of the automotive industry.
