Abstract
Die Erfindung betrifft ein Kunstledermaterial (10), umfassend eine Trägerschicht (5) und eine erste Auflageschicht (4), wobei die erste Auflageschicht (4) Partikel aus einem nachwachsenden Rohstoff umfasst. Ferner betrifft die Erfindung ein Fahrzeug, aufweisend ein mit einem derartigen Kunstledermaterial bezogenes Interieur.The invention relates to an artificial leather material (10) comprising a carrier layer (5) and a first supporting layer (4), the first supporting layer (4) comprising particles made from a renewable raw material. The invention also relates to a vehicle having an interior covered with such an artificial leather material.
Description
Leder findet unter anderem Anwendung als Bezugsmaterial für Automobilinterieurs, beispielsweise Automobilsitze, und wird als belastbares, optisch ansprechendes und insgesamt hochwertiges Material geschätzt. Allerdings stellt die Verarbeitung des Rohleders zum Endprodukt eine erhöhte Umweltbelastung durch die in der Gerbung eingesetzten Chemikalien dar.Leather is used, among other things, as a cover material for automobile interiors, for example automobile seats, and is valued as a resilient, visually appealing and overall high-quality material. However, the processing of rawhide into the end product represents an increased environmental impact due to the chemicals used in tanning.
Kunstleder ist ein Lederimitat. Als Grundgedanke steht hinter der Verwendung von Kunstleder der Verzicht auf Echtleder als tierischem Produkt und die Vermeidung der durch die Echtlederproduktion verursachten ökologischen Probleme.Synthetic leather is an imitation leather. The basic idea behind the use of artificial leather is to dispense with real leather as an animal product and avoid the ecological problems caused by real leather production.
In der Regel wird bei der Kunstlederherstellung ein Verbund aus einem textilen Grundträger, insbesondere ein Gestrick, und einer Kunststoffdeckschicht verwendet. Die Textilwerkstoffe können Naturfaser-, Chemiefaser- oder Mischtextilien sein und wiederum beschichtet sein, beispielsweise mit Weich-PVC. Diese Beschichtung kann je nach Anwendung kompakt oder geschäumt ausgeführt werden. Der Oberfläche kann eine Narbenprägung verliehen werden, sodass sie auch in der optischen bzw. haptischen Struktur dem Leder ähnelt.As a rule, a composite of a textile base carrier, in particular a knitted fabric, and a plastic cover layer is used in the manufacture of artificial leather. The textile materials can be natural fiber, chemical fiber or mixed textiles and in turn be coated, for example with soft PVC. This coating can be made compact or foamed, depending on the application. The surface can be given a grain embossing so that it also resembles leather in terms of its optical or haptic structure.

CN 108978250 A
Ebenso wie die Lederherstellung begegnet auch die Kunstlederherstellung, vor dem Hintergrund eines immer stärker werdenden ökologischen Bewusstseins, Bedenken. Kunstledermaterialien weisen nämlich aufgrund ihres petrochemischen Ursprungs materialspezifische Nachteile auf, die im Besonderen einen negativen Einfluss auf die ökologische Bilanz des Werkstoffes haben. Die verbreitet eingesetzten Kunststoffe Polyvinylchlorid (PVC) und Polyurethan (PU) weisen eine petrochemische Basis auf - es handelt sich somit um einen nicht-nachwachsenden Rohstoff beziehungsweise eine endliche Ressource.Just like leather production, artificial leather production also encounters concerns against the background of an ever increasing ecological awareness. Because of their petrochemical origin, artificial leather materials have material-specific disadvantages, which in particular have a negative impact on the ecological balance of the material. The widely used plastics polyvinyl chloride (PVC) and polyurethane (PU) have a petrochemical basis - it is therefore a non-renewable raw material or a finite resource.
Der Erfindung liegt daher die Aufgabe zugrunde, ein belastbares, optisch ansprechendes und insgesamt hochwertiges Material bereitzustellen, welches gleichzeitig in ökologischer Hinsicht die Nachteile bekannter Ledermaterialien und Kunstledermaterialen zumindest teilweise überwindet.The invention is therefore based on the object of providing a resilient, visually appealing and overall high-quality material which at the same time at least partially overcomes the disadvantages of known leather materials and synthetic leather materials from an ecological point of view.
Gemäß einem ersten Aspekt betrifft die Erfindung ein Kunstledermaterial umfassend:
- - eine Trägerschicht; und
- - eine erste Auflageschicht,
dadurch gekennzeichnet, dass die erste Auflageschicht Partikel aus einem nachwachsenden Rohstoff umfasst.According to a first aspect, the invention relates to an artificial leather material comprising:
- - a carrier layer; and
- - a first layer of overlay,
characterized in that the first coating layer comprises particles made from a renewable raw material.
Das erfindungsgemäße Kunstledermaterial vermindert also den Einsatz nicht-nachwachsender Rohstoffe mittels des Einsatzes von nachwachsenden Rohstoffen. Anders ausgedrückt wird ein belastbares, optisch ansprechendes und insgesamt hochwertiges Material bereitgestellt, welches gleichzeitig in ökologischer Hinsicht die Nachteile bekannter Ledermaterialien und Kunstledermaterialen weitestgehend überwindet. Die Erfindung stellt also eine Verringerung des ökologischen Fußabdrucks von herkömmlich verwendetem Leder oder Kunstleder dar.The artificial leather material according to the invention thus reduces the use of non-renewable raw materials by means of the use of renewable raw materials. In other words, a resilient, visually appealing and overall high-quality material is provided, which at the same time largely overcomes the disadvantages of known leather materials and synthetic leather materials from an ecological point of view. The invention thus represents a reduction in the ecological footprint of conventionally used leather or artificial leather.
Gemäß einer bevorzugten Ausführungsform wird ein Kunstledermaterial beschrieben, wobei der nachwachsende Rohstoff der ersten Auflageschicht ausgewählt ist aus einem oder mehreren der folgenden Gruppe: Holzmehl, Kaffeefrüchte, Maiskolbenspindeln, Zuckerrübenmehl, Getreidestängelmehl, Biertrebermehl.According to a preferred embodiment, an artificial leather material is described, the renewable raw material of the first layer being selected from one or more of the following group: wood flour, coffee fruits, corn cobs, sugar beet flour, grain stalk flour, beer grain flour.

Gemäß einer bevorzugten Ausführungsform wird ein Kunstledermaterial beschrieben, wobei der nachwachsende Rohstoff in der ersten Auflageschicht und/oder in der zweiten Auflageschicht in einer Menge von wenigstens 10 Gew.-%, bevorzugt von wenigstens 20 Gew.-% vorliegt.According to a preferred embodiment, an artificial leather material is described, the renewable raw material being present in the first layer and / or in the second layer in an amount of at least 10% by weight, preferably at least 20% by weight.
Gemäß einer bevorzugten Ausführungsform wird ein Kunstledermaterial beschrieben, wobei die erste Auflageschicht als Haftschicht ausgebildet ist, die die Trägerschicht mit der zweiten Auflageschicht verbindet.According to a preferred embodiment, an artificial leather material is described, the first support layer being designed as an adhesive layer which connects the carrier layer to the second support layer.
Gemäß einer bevorzugten Ausführungsform wird ein Kunstledermaterial beschrieben, wobei die erste Auflageschicht Polyurethane oder Polyole umfasst.According to a preferred embodiment, an artificial leather material is described, the first covering layer comprising polyurethanes or polyols.
Die Haftschicht bindet die Auflageschicht oder die Auflageschichten an die Trägerschicht.The adhesive layer binds the overlay layer or layers to the carrier layer.
Es wurde festgestellt, dass es selbst bei hohen Anteilen an nachwachsenden Rohstoffen in der Haftschicht möglich ist, mittels der Haftschicht ein sicheres Haften der Auflageschicht oder der Auflageschichten an die Trägerschicht zu bewirken.It has been found that even with high proportions of renewable raw materials in the adhesive layer, it is possible, by means of the adhesive layer, to ensure that the support layer or layers adhere reliably to the carrier layer.
Gemäß einer bevorzugten Ausführungsform wird ein Kunstledermaterial beschrieben, wobei die Trägerschicht einen nachwachsenden Rohstoff umfasst, insbesondere Naturfasern, die bevorzugt ausgewählt sind aus einem oder mehreren der folgenden Gruppe: Leinen, Nessel, Hanf, Ramie, Ananas, und Baumwolle.According to a preferred embodiment, an artificial leather material is described, the carrier layer comprising a renewable raw material, in particular natural fibers, which are preferably selected from one or more of the following groups: linen, nettle, hemp, ramie, pineapple and cotton.
Gemäß einer bevorzugten Ausführungsform wird ein Kunstledermaterial beschrieben, wobei das Kunstledermaterial ferner umfasst:
- - eine zweite Auflageschicht,
- - a second layer of overlay,
Gemäß einer bevorzugten Ausführungsform wird ein Kunstledermaterial beschrieben, wobei die erste Auflageschicht Partikel aus einem nachwachsenden Rohstoff, insbesondere Silberhaut von Kaffeefrüchten, umfasst und der nachwachsende Rohstoff in einer Menge von wenigstens 10 Gew.-%, bevorzugt von wenigstens 20 Gew.-%, in der ersten Auflageschicht vorliegt und wobei die zweite Auflageschicht Partikel aus einem nachwachsenden Rohstoff, insbesondere Silberhaut von Kaffeefrüchten, umfasst und der nachwachsende Rohstoff in einer Menge von wenigstens 10 Gew.-%, bevorzugt von wenigstens 20 Gew.-% vorliegt, und die Trägerschicht im Wesentlichen aus einem Gestrick gefertigt ist.According to a preferred embodiment, an artificial leather material is described, wherein the first layer comprises particles of a renewable raw material, in particular silver skin from coffee fruits, and the renewable raw material in an amount of at least 10% by weight, preferably at least 20% by weight, in the first support layer is present and wherein the second support layer comprises particles of a renewable raw material, in particular silver skin from coffee fruits, and the renewable raw material is present in an amount of at least 10% by weight, preferably at least 20% by weight, and the carrier layer in the Is essentially made of a knitted fabric.
Hierdurch ist es möglich, dass das Ledermaterial insgesamt einen Anteil von nachwachsenden Rohstoffen von wenigstens 10 Gew.-%, bevorzugt von wenigstens 20 Gew.-%, weiter bevorzugt von wenigstens 30 Gew.-% aufweist.This makes it possible for the leather material to have a total proportion of renewable raw materials of at least 10% by weight, preferably of at least 20% by weight, more preferably of at least 30% by weight.
Gemäß einer bevorzugten Ausführungsform wird ein Kunstledermaterial beschrieben, wobei die zweite Auflageschicht schaumstoffartig ausgebildet ist.According to a preferred embodiment, an artificial leather material is described, the second support layer being formed like a foam.
Es wurde herausgefunden, dass insbesondere, wenn die erste Auflageschicht und die zweite Auflageschicht Silberhautpartikel in einer Menge von wenigstens 20 Gew.-% aufweisen und die Trägerschicht im Wesentlichen aus einem Gewebe gefertigt ist, ein Gesamtanteil von nachwachsenden Rohstoffen von 30 Gew.-% oder mehr in dem Kunstledermaterial möglich ist, ohne dass die Eigenschaften des Kunstleders, etwa wie die Reißfestigkeit, wesentlich eingeschränkt werden. Es ist damit also möglich, ein belastbares, optisch ansprechendes und insgesamt hochwertiges Material bereitzustellen, welches gleichzeitig in ökologischer Hinsicht die Nachteile bekannter Ledermaterialien und Kunstledermaterialen zumindest teilweise überwindet.It has been found that, in particular when the first coating layer and the second coating layer have silver skin particles in an amount of at least 20% by weight and the carrier layer is essentially made of a fabric, a total proportion of renewable raw materials of 30% by weight or more is possible in the artificial leather material without the properties of the artificial leather, such as tear resistance, being significantly restricted. It is thus possible to provide a resilient, visually appealing and overall high-quality material which at the same time at least partially overcomes the disadvantages of known leather materials and synthetic leather materials from an ecological point of view.
