Description

Technisches GebietTechnical area

Die Erfindung betrifft einen Veloumadelvliesstoff, welcher durch Ablegen eines gegebenenfalls vorverfestigten Vlieses auf einer bürstenartigen Unterlage und Nadeln des Vlieses auf dieser Unterlage hergestellt wird. Des Weiteren betrifft die Erfindung bevorzugte Verwendungen des Veloumadelvliesstoffs.The invention relates to a Veloumadelvliesstoff which is prepared by depositing an optionally pre-bonded nonwoven on a brush-like pad and needles of the web on this pad. Furthermore, the invention relates to preferred uses of the Veloumadelvliesstoffs.

Stand der TechnikState of the art

Aus der DE 34 44 763 A1 sind eine Vorrichtung und ein Verfahren zur Herstellung eines Veloumadelvliesstoffs bekannt, bei welchem ein vorgenadeltes Stapelfaservlies auf eine umlaufende, bürstenartige Stichunterlage aufgelegt und dann unter einer Polausbildung auf der der Stichunterlage zugekehrten Seite genadelt wird. Da bei diesem Verfahren die von den Nadeln erfassten Fasern in die Bürste der Stichunterlage hineingenadelt werden, erhält der in dieser Weise genadelte Vliesstoff ein velourartiges Aussehen.From the DE 34 44 763 A1 An apparatus and a method for producing a Veloumadelvliesstoffs are known in which a pre-needled Stapelfaservlies is placed on a rotating, brush-like stitch backing and then needled under a Polausbildung on the stitch backing facing side. In this method, since the fibers grasped by the needles are needled into the brush of the stitch backing, the nonwoven fabric needled in this manner becomes a velor-like appearance.

Um die Verzugsfestigkeit eines solchen Veloumadelvliesstoffs zu steigern, wird in der DE 44 09 771 A1 weiter vorgeschlagen, das Stapelfaservlies unter Zwischenlage einer Schicht mit einer höheren Verzugsfestigkeit als das Stapelfaservlies, insbesondere eines Spinnvlieses, auf die bürstenartige Stichunterlage aufzulegen und dann das Verfahren so zu führen, dass beim Nadeln die Polfasern durch die Schicht mit der höheren Verzugsfestigkeit gezogen werden. Hierbei ist gemäß dem Dokument insbesondere darauf zu achten, dass das Flächengewicht der Zwischenschicht aus Spinnvlies möglichst gering ist, so dass zum einen die Polausbildung durch die Zwischenschicht nicht behindert wird und zum anderen die Zwischenschicht im optischen Erscheinungsbild des Veloumadelvliesstoffs aus Stapelfasern nicht in Erscheinung tritt.In order to increase the draft resistance of such a Veloumadelvliesstoffs, is in the DE 44 09 771 A1 further proposed, the staple fiber fleece with the interposition of a layer with a higher tensile strength than the staple fiber fleece, in particular a spunbonded, on the brush-like Apply the underlay and then run the procedure so that when needling the pile fibers are pulled through the layer with the higher resistance to distortion. In this case, according to the document, particular care must be taken that the basis weight of the intermediate layer of spunbonded is minimized, so that on the one hand the Polausbildung is not hindered by the intermediate layer and on the other hand, the intermediate layer does not appear in the optical appearance of Veloumadelvliesstoffs of staple fibers.

Veloumadelvliesstoffe der beschriebenen Art werden im zunehmenden Maße zur Auskleidung von Kraftfahrzeuginnenräumen eingesetzt. Nachteilig ist dabei, dass, um die für diese Anwendung erforderlichen Abriebsfestigkeit zu erreichen, dem Veloumadelvliesstoff 200 bis 300 g/m2 tiefziehfähiger Latex-Binder zugegeben werden muss. Latex-Binder ist nicht nur sehr teuer, er enthält auch flüchtige organische Verbindungen (VOCs), die in den Kraftfahrzeuginnenraum entweichen (Fogging). Im Hinblick auf das allgemein steigende Umwelt-, Gesundheits- und Qualitätsbewusstsein sind solche Emissionen in Innenräumen zum Beispiel in Kraftfahrzeugen, Bauprodukten, oder auch Wohninnenräumen nicht mehr hinnehmbar.Veloumwoven nonwovens of the type described are increasingly used for lining of motor vehicle interiors. The disadvantage here is that in order to achieve the abrasion resistance required for this application, 200 to 300 g / m 2 of deep-drawable latex binder must be added to the velor needling fabric. Latex binder is not only very expensive, it also contains volatile organic compounds (VOCs) that escape into the vehicle interior (fogging). In view of the general increase in environmental, health and quality awareness, such indoor emissions are no longer acceptable, for example in motor vehicles, construction products or residential interiors.

Darstellung der ErfindungPresentation of the invention

Aufgabe der Erfindung ist, einen Veloumadelvliesstoff, insbesondere zur Auskleidung von Innenräumen, bereitzustellen, welcher den hohen Anforderungen an Umwelt-, Gesundheitsverträglichkeit und Qualität genügt und sich gleichwohl durch sehr gute mechanische Eigenschaften, wie zum Beispiel eine hohe Abriebfestigkeit, auszeichnet.The object of the invention is to provide a Veloumadelvliesstoff, especially for the lining of interiors, which meets the high demands on environmental, health and quality and yet characterized by very good mechanical properties, such as a high abrasion resistance.

Diese Aufgabe wird mit einem Veloumadelvliesstoff nach Patentanspruch 1 gelöst. Patentanspruch 9 betrifft eine textile Verkleidung, welche einen erfindungsgemäßen Veloumadelvliesstoff enthält. Die Patentansprüche 19 und 20 sind auf bevorzugte Verwendungen der textilen Verkleidung gerichtet. Die Unteransprüche betreffen bevorzugte Ausgestaltungen der Erfindung.This object is achieved with a Veloumadelvliesstoff according to claim 1. Claim 9 relates to a textile covering, which a Veloumwoven nonwoven fabric according to the invention contains. The claims 19 and 20 are directed to preferred uses of the textile covering. The subclaims relate to preferred embodiments of the invention.

Im Folgenden sollen im Sinne der Erfindung unter Filamenten Endlosfasern verstanden werden. Unter Stapelfasern oder Fasern sollen demgegenüber im Folgenden Fasern mit endlicher Länge verstanden werden.In the following, filaments mean continuous fibers within the meaning of the invention. By contrast, staple fibers or fibers are to be understood below to mean fibers of finite length.

Gemäß der Erfindung ist bei einem Veloumadelvliesstoff, welcher durch Ablegen eines gegebenenfalls vorverfestigten Vlieses auf einer bürstenartigen Stichunterlage und Nadeln des Vlieses auf dieser Stichunterlage vorgesehen, dass das Vlies ein Spinnvlies mit Filamenten umfasst, wobei die Filamente Mehrkomponentenfilamente mit wenigstens einer hochschmelzenden und wenigstens einer thermisch aktivierbaren niedrigschmelzenden Komponente umfassen.According to the invention, in a Veloumadelvliesstoff which by depositing an optionally pre-bonded nonwoven on a brush-like stitch backing and needles of the web on this stitch backing provided that the fleece comprises a spunbonded with filaments, wherein the filaments Mehrkomponentenfilamente with at least one refractory and at least one thermally activatable low-melting component include.

Es wurde in überraschender Weise festgestellt, dass mit einem Veloumadelvliesstoff der oben beschriebenen Art auch ohne Verwendung eines zusätzlichen chemischen Bindemittels sehr hohe Abriebsfestigkeiten erreicht werden, Der bei Anwendungen in Kraftfahrzeuginnenräumen zur Erhöhung der Abriebfestigkeit eines Veloumadelvliesstoffs üblicherweise auf die Vliesstoffrückseite aufgetragene Latexanstrich kann komplett entfallen. Ein erfindungsgemäßer Veloumadelvliesstoff ist damit frei von fogging-aktiven Stoffen. Die mit dem bekannten Latexanstrich verbundene gesundheitschädliche Emission flüchtiger Kohlenwasserstoffe wird bei einem erfindungsgemäßen Veloumadelvliesstoff vollständig vermieden. Der erfindungsgemäße Veloumadelvliesstoff genügt damit den höchsten Anforderungen an Gesundheits-, Umweltverträglichkeit und Qualität. Der Verzicht auf Latexbinder führt darüber hinaus noch zu einem deutlichen Kostenvorteil.It has surprisingly been found that with a Veloumadelvliesstoff of the type described above, even without the use of an additional chemical binder very high abrasion resistance can be achieved, which in applications in motor vehicle interiors to increase the abrasion resistance of a Veloumadelvliesstoffs usually applied to the nonwoven back latex paint can be completely eliminated. An inventive Veloumadelvliesstoff is thus free of fogging-active substances. The harmful emissions of volatile hydrocarbons associated with the known latex paint are completely avoided in a bicomponent nonwoven fabric according to the invention. The Veloumadelvliesstoff invention thus meets the highest standards of health, environmental compatibility and quality. The absence of latex binder also leads to a significant cost advantage.

Gemäß der Erfindung umfasst der Veloumadelvliesstoff ein Spinnvlies mit Filamenten. Die Verwendung eines Spinnvlies hat nicht nur den Vorteil, dass es dem textilen Flächengebilde in an sich bekannter Weise eine gewisse Festigkeit verleiht. Spinnvliese sind auch sehr kostengünstig herzustellen. Allerdings zeichnen sich Spinnvliese im Gegensatz zu Stapelfaservliesen üblicherweise durch ein sehr glattes, wenig voluminöses Erscheinungsbild aus. Die Filamente liegen nahezu ausschließlich in einer horizontalen Ebene. Den Materialien fehlt es völlig an Bausch und velourartiger Charakteristik. Sie scheinen daher auf den ersten Blick ungeeignet für die Ausbildung eines velourartigen Nadelvlieses zu sein. So wird auch in der eingangs beschriebenen DE 44 09 771 A1 ausdrücklich erwähnt, dass das Flächengewicht des als Verstärkungslage eingefügten Spinnvlieses so gering gewählt werden muss, dass es optisch nicht in Erscheinung tritt.According to the invention, the Veloumadelvliesstoff comprises a spunbonded with filaments. The use of a spunbonded fabric not only has the advantage that it gives the textile fabric a certain strength in a manner known per se. Spunbonded fabrics are also very inexpensive to produce. However, unlike staple fiber webs, spunbonded webs are usually characterized by a very smooth, less voluminous appearance. The filaments lie almost exclusively in a horizontal plane. The materials are completely lacking in bulk and velor-like characteristics. At first glance, therefore, they seem to be unsuitable for the formation of a velor-like needle felt. So also in the beginning described DE 44 09 771 A1 expressly mentioned that the basis weight of the inserted as a reinforcing layer spunbonded fabric must be chosen so low that it does not appear visually.

Es hat sich nun aber in überraschender Weise gezeigt, dass sich auch bei Spinnvliesen auch bei hohen Flächengewichten beim Vemadeln auf einer bürstenartigen Stichunterlage, so wie beispielsweise in der DE 43 44 763 A1 beschrieben, ein bauschiges, textiles Flächengebilde erzielen lässt, das ein velourartiges Erscheinungsbild aufweist. Sogar die für Veloumadelvliesstoffe wichtige Wiedererholung des Bausches bei Belastung wird erreicht. Dabei behält das genadelte Spinnvlies seine an sich bekannten guten Eigenschaften, wie hohe Verzugsfestigkeit, sehr gute Verformbarkeit, hohe Dimensionsstabilität und Abriebfestigkeit bei.However, it has now surprisingly been found that also in spunbonded fabrics, even at high basis weights when needling on a brush-like stitch backing, such as in the DE 43 44 763 A1 described, can achieve a bulky, textile fabric, which has a velor-like appearance. Even the recovery of bulking under load, which is important for velor needles, is achieved. In this case, the needled spunbonded retains its well-known good properties, such as high tensile strength, very good ductility, high dimensional stability and abrasion resistance.

Das Wiedererholungsvermögen, die Verzugsfestigkeit und Dimensionsstabilität eines erfindungsgemäßen Veloumadelvliesstoffs lassen sich noch steigern, wenn es nach dem Nadeln noch thermisch verfestigt wird.The recovery, the tensile strength and dimensional stability of a Veloumadelvliesstoffs invention can be increased even if it is still thermally solidified after needling.

Ein erfindungsgemäßer Veloumadelvliesstoff kann mittels eines Verfahrens hergestellt werden, wie es beispielsweise in der oben erwähnten DE 34 44 763 A1 beschrieben wird. Besondere Verfahrensvarianten, die zum Beispiel zu einer Strukturierung der Oberfläche eines Veloumadelvliesstoffs führen, sind noch aus der EP 0 411 647 A1 bekannt. Dabei kommen beispielsweise je nach gewünschter Strukturierung Gabel- und/oder Kronnadeln zum Einsatz. Entsprechend werden auch ein- oder mehrstufige Verfahren beschrieben. Auch diese Verfahren sind ohne Beschränkung der Allgemeinheit auf einen erfindungsgemäßen Veloumadelvliesstoff anwendbar.An inventive Veloumadelvliesstoff can be prepared by a method, as for example in the above-mentioned DE 34 44 763 A1 is described. Special process variants that lead, for example, to a structuring of the surface of a Veloumadelvliesstoffs are still from the EP 0 411 647 A1 known. Depending on the desired structuring, fork and / or crown needles are used, for example. Accordingly, one or more stages are described. These methods are also applicable without limitation to the generality of a Veloumadelvliesstoff invention.

Gemäß der Erfindung umfassen die Filamenten Mehrkomponentenfilamente mit wenigstens einer hochschmelzenden und wenigstens einer thermisch aktivierbaren niedrigschmelzenden Komponente, vorzugsweise Bikomponentenfilamente. Bikomponentenfilamente sind an sich bekannt. Sie weisen eine niedrigschmelzende Komponente aus einem niedrigschmelzenden Polymer und eine hochschmelzende Komponente aus einem hochschmelzenden Polymer auf.According to the invention, the filaments comprise multi-component filaments with at least one refractory component and at least one thermally activatable low-melting component, preferably bicomponent filaments. Bicomponent filaments are known per se. They have a low-melting component of a low-melting polymer and a high-melting component of a high-melting polymer.

Die oben erwähnte thermisch aktivierbare niedrigschmelzende Komponente übemimmt erfindungsgemäß die Funktion eines Bindemittels bzw. des Latexbinders, ohne jedoch die mit der Verwendung dieses Binders bzw. des sonstigen chemischen Bindemittels verbundenen Nachteile, wie Fogging, geringe Recyclebarkeit usw., aufzuweisen. Der Schmelzpunkt der niedrigschmelzenden Komponente sollte vorzugsweise etwa 10 °C bis 20 °C unterhalb des Schmelzpunktes der höher schmelzenden Komponente liegen, damit diese beim thermischen Aktivieren nicht zerstört wird.The above-mentioned thermally activatable low-melting component according to the invention performs the function of a binder or of the latex binder, but without the disadvantages associated with the use of this binder or the other chemical binder, such as fogging, low recyclability, etc., exhibit. The melting point of the low melting component should preferably be about 10 ° C to 20 ° C below the melting point of the higher melting component so that it will not be destroyed upon thermal activation.

Der Anteil an Bikomponentenfilamenten im Spinnvlies sollte einen Anteil von 5 % (bezogen auf das Gesamtflächengewicht des Veloumadelvliesstoffs) nicht unterschreiten, das sich ansonsten die Abriebfestigkeit zu stark verschlechtern würde. Vorzugsweise liegt der Anteil über 15 %The proportion of bicomponent filaments in the spunbonded fabric should not account for 5% (based on the total basis weight of the bicomponent nonwoven fabric) fall below, otherwise the abrasion resistance would deteriorate too much. Preferably, the proportion is over 15%

Das Spinnvlies kann ein- oder mehrlagig aufgebaut sein. Es kann aus einer oder mehreren Filamentarten bestehen. Auch die Beimischung von Stapelfasern ist möglich. Der Anteil an Stapelfasern sollte hierbei jedoch einen Wert von 75% bezogen auf das Gesamtflächengewicht des Veloumadelvliesstoffs nicht überschreiten, da bei höheren Werten die Abriebsfestigkeit wie auch die Zugfestigkeit und Formstabilität stark abnehmen.The spunbonded fabric can be constructed in one or more layers. It can consist of one or more filament types. The addition of staple fibers is possible. The proportion of staple fibers should, however, not exceed a value of 75% based on the total basis weight of the Veloumadelvliesstoffs, since at higher levels, the abrasion resistance as well as the tensile strength and dimensional stability decrease sharply.

Auch die Stapelfasern können aus Mehr-, vorzugsweise Bikomponentenfasem, ausgebildet sein, wobei bezüglich der bevorzugt verwendeten Polymere die obigen Ausführungen gelten.The staple fibers may also be formed from multi-component, preferably bicomponent fibers, the above statements being applicable to the polymers used with preference.

Die Beimischung von Stapelfasern kann einerseits so erfolgen, dass die Stapelfasern in den Spinnvliesfilamentstrom injiziert werden. Es ist jedoch auch möglich, die Stapelfasern auf einer Spinnvlieslage abzulegen oder zwischen zwei Spinnvlieslagen und das Einbringen der Fasern in die Spinnvlieslagen über den Nadelprozess vorzunehmen. Des Weiteren können beide Lagen separat produziert werden und erst in einem nachgelagerten Schritt, beispielsweise mittels des Vemadelungsschritts, zusammengefügt werden.The admixture of staple fibers on the one hand can be done so that the staple fibers are injected into the spunbond filament stream. However, it is also possible to deposit the staple fibers on a spunbonded layer or to make between two spunbonded layers and the introduction of the fibers into the spunbonded layers via the needle process. Furthermore, both layers can be produced separately and assembled in a subsequent step, for example by means of the needling step.

Durch Beimischung von gekräuselten Stapelfasern lassen sich der Bausch und das Wiedererholungsvermögen des Bauschs noch verbessern. Dieser Effekt lässt sich auch durch den Einsatz gekräuselter Endlosfilamente erreichen.The addition of crimped staple fibers improves the bulk and the recovery of bulk. This effect can also be achieved by using crimped endless filaments.

Die Zugabe von Stapelfasern kann aber in vorteilhafter Weise auch dazu genutzt werden, um eine reproduzierbare und homogene Einfärbung des Veloumadelfilzes zu erzielen. Dabei sind alleine die Stapelfasern die Farbträger. Die Einstellung der Farbe erfolgt über die Zudosierung. Eine solche reproduzierbare Farbeinstellung lässt sich auch über die Einfärbung der Endlosfilamente im kontinuierlichen Spinnprozess erzielen. Allerdings ist der Stapelfaserprozess in der Regel wesentlich flexibler und kann daher Farbänderungen schneller umsetzen.However, the addition of staple fibers can also be used to advantage in order to achieve a reproducible and homogeneous coloring of Veloumadelfilzes. Only the staple fibers are the color carrier. The adjustment of the color takes place via the metering. Such reproducible color adjustment can also be achieved by coloring the continuous filaments in the continuous spinning process. However, the staple fiber process is usually much more flexible and can therefore implement color changes faster.

Erfindungsgemäß können mehrere unterschiedliche Fasern bzw. Filamente zum Einsatz kommen. Die Unterschiede können beispielsweise in der Zusammensetzung oder aber auch in der Faser- bzw. Filamentdicke liegen. Hierbei kann ein stufenartiger oder auch gradientenartiger Aufbau der Lagen aus unterschiedlichen Fasern und/oder Filamenten vorgesehen sein. So ist beispielsweise die Ausbildung diskreter Übergänge zwischen Lagen mit unterschiedlichen Fasern und/oder Filamenten oder aber eine kontinuierliche Anreicherung einer Filament- oder Faserart zu einer der Oberflächen hin denkbar. Umfasst eine solche Faser bzw. ein solches Filament ein niedrigschmelzendes, wärmeaktivierbares Bindepolymer, so kann auf diese einfache Weise eine Haftvermittlerschicht ausgebildet werden. Bei gradientenartigem Aufbau führt ein solches Bindepolymer noch zusätzlich im Inneren der Lage zu einer Verfestigung und Stabilisierung.According to the invention, a plurality of different fibers or filaments can be used. The differences may be, for example, in the composition or else in the fiber or filament thickness. Here, a step-like or even gradient-like structure of the layers of different fibers and / or filaments can be provided. For example, the formation of discrete transitions between layers with different fibers and / or filaments or a continuous enrichment of a filament or fiber type to one of the surfaces is conceivable. If such a fiber or filament comprises a low-melting, heat-activatable binding polymer, then an adhesion promoter layer can be formed in this simple manner. With a gradient-like structure, such a binder polymer additionally leads to solidification and stabilization in the interior of the layer.

Eine textile Verkleidung, die einen erfindungsgemäßen Veloumadelvliesstoff umfasst, ist aufgrund ihrer besonderen mechanischen Stabilität wie auch Umwelt-, Gesundheitsverträglichkeit und Qualität ganz besonders gut für Anwendungen im Objektbereich geeignet. Zu diesem zählen alle Zielgruppen, auch die nicht dem privaten Bereich zuzuordnen sind, wie zum Beispiel Büros, Schulen, Banken, Versicherungen, Hotels, der Sozial- und Pflegebereich, Sportstätten, insbesondere auch die Innenausstattungen im Automobilbereich, in der Schifffahrt, der Bahn usw.A textile cover comprising a velor spunbonded fabric according to the invention is particularly well suited for applications in the field of objects due to its special mechanical stability as well as environmental, health and quality. This includes all target groups, even those not belonging to the private sector, such as offices, schools, banks, insurance companies, hotels, the social and care sector, sports facilities, in particular also the interiors in the automotive sector, in shipping, railways, etc ,

Im Objektbereich werden extrem hohe Anforderungen an die technische Qualität gestellt. Diesen Anforderungen wird ein erfindungsgemäße textile Verkleidung gerecht. Bevorzugt sind hier Anwendungen im Bereich Kraftfahrzeuginnenraumauskleidung, sowohl Fahrgastraum- als Kofferrauminnenauskleidung, sowie Teppichböden, sowohl als Bahnenware als auch in Form von Fliesen. Aber auch andere Anwendungen für eine solche textile Verkleidung sind möglich, z. B. als Wandverkleidung, Trennwänden usw. Aufgrund der obigen Ausführungen liegt es auf der Hand, dass eine erfindungsgemäße textile Verkleidung natürlich auch im privaten Bereich, beispielsweise im Wohnbereich, Anwendung finden kann.In the commercial sector, extremely high demands are placed on the technical quality. These requirements is a textile according to the invention Fairing fair. Preference is given here to applications in the field of motor vehicle interior lining, both passenger compartment and trunk interior lining, as well as carpets, both as sheet goods and in the form of tiles. But other applications for such a textile cladding are possible, for. As wall cladding, partitions, etc. Due to the above, it is obvious that a textile cladding according to the invention, of course, in the private sector, for example in the living area, application can be found.

Eine erfindungsgemäße textile Verkleidung kann für die oben genannten Anwendungen beispielsweise auch flammfest, antistatisch oder antimikrobiell ausgerüstet sein.A textile covering according to the invention may, for example, also be made flame-resistant, antistatic or antimicrobial for the abovementioned applications.

Die Verwendungsmöglichkeiten eines erfindungsgemäßen Veloumadelvlieses bzw. einer erfindungsgemäßen textilen Verkleidung sind keinesfalls auf die oben genannten konkreten Anwendungsgebiete beschränkt.The possible uses of a velor spun web or a textile cladding according to the invention are by no means limited to the specific fields of application mentioned above.

Insbesondere für Anwendungen im Bereich der Auskleidung von Kraftfahrzeuginneräumen oder im Bereich Teppichböden kann es vorteilhaft sein, wenn die erfindungsgemäße textile Verkleidung mit einer so genannten Schwerschicht versehen ist. Der Einsatz von Schwerschichten ist im Bereich der Kraftfahrzeuginnenraumauskleidung an sich bekannt. Sie dienen der Entkopplung nach dem Masse-Feder-Prinzip. Die Schwerschicht wird entweder mittels einer Schicht aus PE unter Zufuhr von Wärme oder direkt auf den Teppich extrudiert und braucht dann keinen weiteren Haftvermittler. Die Schwerschicht besteht üblicherweise aus CaCO3 und EVA. Darauf wird dann ein Entkoppler wie ein Cotton Shoddy oder ein Schaum aufgebracht. Die Schwerschicht kann gemäß einer bevorzugten Ausführungsform der Erfindung aber auch in Form eines Vliesstoffs, insbesondere eines Spinnviiesstoffs aufgebracht werden. Hierdurch vereinfacht sich nicht nur die Verfahrensführung, auch unter dem Gesichtspunkt der Recyclebarkeit können sich hieraus, wie weiter unten noch ausgeführt wird, Vorteile ergeben.In particular for applications in the field of lining of motor vehicle interior spaces or in the area of carpets, it can be advantageous if the textile covering according to the invention is provided with a so-called heavy layer. The use of heavy layers is known per se in the field of automotive interior lining. They are used for decoupling according to the mass-spring principle. The heavy layer is extruded either by means of a layer of PE with the addition of heat or directly onto the carpet and then needs no further adhesion promoter. The heavy layer usually consists of CaCO 3 and EVA. Then a decoupler such as a cotton shoddy or a foam is applied. However, according to a preferred embodiment of the invention, the heavy layer can also be applied in the form of a nonwoven fabric, in particular a spun-lye fabric. This not only simplifies the Process management, also from the viewpoint of recyclability, this can, as will be explained below, provide advantages.

Weiterhin kann eine erfindungsgemäße Verkleidung gemäß einer weiteren bevorzugten Ausführungsform entweder in Kombination mit der Schwerschicht oder alleine mit einer Schalldämpfungslage ausgerüstet sein. Die Schalldämpfungslage kann in an sich bekannter Weise durch ein sog. Cotton Shoddy mit Zwischenlage, die die Luftdurchlässigkeit begrenzt, gebildet werden, oder aber auch durch ein Mikrofaservlies in Verbindung mit einem Cotton Shoddy oder einem Nadelvlies oder durch ein Nadelvlies selbst.Furthermore, according to a further preferred embodiment, a lining according to the invention can be equipped either in combination with the heavy layer or alone with a sound damping layer. The sound-damping layer can be formed in a manner known per se by a so-called cotton shoddy with an intermediate layer which limits the air permeability, or else by a microfiber fleece in conjunction with a cotton shoddy or a needle fleece or by a needle fleece itself.

Die oben beschriebenen Lagen und/oder Schichten werden vorzugsweise mittels Bindeschichten miteinander verbunden. Für die Bindeschichten können herkömmliche Binder verwendet werden. Unter dem Gesichtspunkt der Umwelt- und Gesundheitsverträglichkeit wie auch unter ökonomischen Gesichtspunkten (vereinfachte Verfahrensführung, weniger Prozessschritte) kommen für diese Bindeschichten gemäß einer besonders bevorzugten Ausführungsform der Erfindung ebenfalls Lagen aus Mehrkomponentenfilamenten und/oder -fasern, vorzugsweise aus Bikomponentenfilamenten und/oder -fasern zum Einsatz. Es können auch zusätzlich oder alleine auch Monofilamente oder -fasern, die aus einem niedrigschmelzenden Polymer, wie zum einem Copolymer, bestehen, für die Bindeschicht verwendet werden. Auf chemische Bindemittel, die zu dem bekannten Fogging-Problem führen können, kann bei diesen zuletzt genannten Ausführungsformen dann ganz verzichtet werden.The layers and / or layers described above are preferably connected to one another by means of bonding layers. Conventional binders can be used for the tie layers. According to a particularly preferred embodiment of the invention, layers of multicomponent filaments and / or fibers, preferably of bicomponent filaments and / or fibers, also come from the point of view of environmental and health compatibility as well as from an economic point of view (simplified process control, fewer process steps) Commitment. Monofilaments or fibers consisting of a low melting polymer, such as a copolymer, may also be used in addition or alone for the bonding layer. On chemical binders that can lead to the known fogging problem, can be completely dispensed with in these last-mentioned embodiments.

Als Bikomponentenfilamente und/oder -fasern werden für die in der vorliegenden Anmeldung beschriebenen Anwendungen gemäß einer bevorzugten Ausführungsform der Erfindung Kern-/Mantel-, Side-By-Side-Island -In The-Sea und/oder PIE(auch Hollow-PIE) -Filamente bzw. -fasern eingesetzt. Bikomponentenfilamente oder -fasern mit trilobaler Geometrie oder Fasern oder Filamente aus Spinndüsen mit knochenförmiger Kapillar-Geometrie (=konzentrierte Anordnung von Binde- und Matrixpolymer) führen zu einer besseren Verankerung der Fasern oder Filamente im Vliesstoff und damit zu einer noch weiter erhöhten Zugfestigkeit und Abriebfestigkeit des Materials.As bicomponent filaments and / or fibers, for the applications described in the present application according to a preferred embodiment of the invention, core / shell, side-by-side Iceland-In The-Sea and / or PIE (also Hollow-PIE) -Filamente or fibers used. Bicomponent filaments or fibers with trilobal geometry or Fibers or filaments from spinnerets with bone-shaped capillary geometry (= concentrated arrangement of binder and matrix polymer) lead to a better anchoring of the fibers or filaments in the nonwoven fabric and thus to an even higher tensile strength and abrasion resistance of the material.

Über den Anteil an Mehrkomponenten- oder Bikomponentenfilamenten und/oder -fasern lässt sich auch in einfacher Weise die Steifigkeit der textilen Verkleidung einstellen. Je höher dieser Anteil ist, desto steifer wird das Material.By way of the proportion of multicomponent or bicomponent filaments and / or fibers, the stiffness of the textile covering can also be adjusted in a simple manner. The higher this proportion, the stiffer the material becomes.

Die niedrigschmelzende Komponente der Bikomponentenfilamente oderfasern umfasst ohne Beschränkung der Allgemeinheit vorzugsweise CoPET (Copolyester), CoPA (Copolyamid), PA (Polyamid), PP (Polypropylen), Copolypropylen (CoPP), ataktisches PP und/oder PE (Polyethylen), die hochschmelzende Komponente vorzugsweise PET (Polyester), PA (Polyamid), PLA (Polylactid), PBT (Polybutylen) und/oder PP (Polypropylen). Gleiches gilt auch für die wenigstens eine niedrigschmelzende Komponente bzw. die wenigstens eine hochschmelzende Komponente von erfindungsgemäß eingesetzten Mehrkomponentenfilamenten und -fasern.The low melting component of the bicomponent filaments or fibers preferably includes, but is not limited to, CoPET (copolyester), CoPA (copolyamide), PA (polyamide), PP (polypropylene), copolypropylene (CoPP), atactic PP, and / or PE (polyethylene), the refractory component preferably PET (polyester), PA (polyamide), PLA (polylactide), PBT (polybutylene) and / or PP (polypropylene). The same also applies to the at least one low-melting component or the at least one high-melting component of multi-component filaments and fibers used according to the invention.

Gemäß einer weiteren besonders bevorzugten Ausführungsform der Erfindung bestehen die Filamente und/oder Fasern aller Lagen und/oder Schichten aus ein- und demselben Polymer und/oder seinen Derivaten. Dies hat den Vorteil der einfacheren Recyclebarkeit. Vorzugsweise besteht die Textile Verkleidung aus Polypropylen und/oder seinen Derivaten oder aus Polyester und/oder seinen Derivaten oder aus Polyamid und/oder seinen Derivaten. Insbesondere bei textilen Auskleidungen werden häufig Formteile aus der Bahnenware ausgestanzt. Die Ausstanzabfälle können bei Verwendung der obigen Materialien wieder für die Filament und/oder Stapelfaserherstellung verwendet werden.According to a further particularly preferred embodiment of the invention, the filaments and / or fibers of all layers and / or layers consist of the same polymer and / or its derivatives. This has the advantage of easier recyclability. The textile cladding preferably consists of polypropylene and / or its derivatives or of polyester and / or its derivatives or of polyamide and / or its derivatives. In particular, in textile liners moldings are often punched out of the sheet goods. The stamping waste can be reused for filament and / or staple fiber making using the above materials.
