Description

Stand der Technik:State of the art:

Die Beschichtung und Färbung von Leder ist ein seit langen bekanntes Verfahren der Veredlung von Leder. Ausgeführt wird die Beschichtung durch handelsübliche polymere Produkte, beispielsweise auf Basis von Polyacrylaten, Polyuethanen und vernetzbaren organischen Silanen.The coating and coloring of leather is a long-known method of finishing leather. The coating is carried out by commercially available polymeric products, for example based on polyacrylates, polyurethanes and crosslinkable organic silanes.

Insbesondere im Automobilbereich schätzt man die Anwendung dünner und weicher Leder aufgrund des besseren Sitzkomforts. Nachteilig bei diesen Ledern ist die mit abnehmender Schichtdicke des Leders auch abnehmende Reißfestigkeit. Häufiger treten irreversible Risse auf, die ein Ersatz des ansonsten sehr nachhaltigen Ledermaterials erfordern.Particularly in the automotive sector, the application of thin and soft leather is appreciated for its better seating comfort. A disadvantage of these leathers is the decreasing tear strength with decreasing layer thickness of the leather. More often, irreversible cracks occur which require replacement of the otherwise very sustainable leather material.

Die vorliegende Erfindung dient der Verlängerung der Lebensdauer dünner Leder wie z. B. Spaltleder oder Narbenspaltledern von 0,3–1,5 mm Stärke mit der Option gleichzeitig eine aktive Funktionsschicht einzubringen.The present invention serves to extend the life of thin leather such. B. split leather or grain split leather 0.3-1.5 mm thickness with the option at the same time to introduce an active functional layer.

Bei der Funktionsschicht kann es sich um verschiedene Arten von Funktionalitäten handeln wie beispielsweise eine elektrisch leitfähige Schicht, eine zusätzlich flammhemmende Schicht sowie eine elektrostatische Barriere handeln. Ebenso kann eine Barriere für organische Organismen wie z. B. Milben sowie eine antimikrobielle Funktionsschicht, beispielsweise durch Anwendung von Silber oder antimikrobiellen Substanzen aufgebracht werden. Die Funktionsschicht wird mit Hilfe oben genannter polymerer Produkte auf dem Leder oder der textilen Schicht erzeugt. Dabei werden die gelösten oder dispergierten Funktionssubstanzen mit dem polymeren Binder vermischt und die Beschichtung auf marktgängigen Beschichtungsanlagen aufgebracht. Als Funktionssubstanzen zur Erreichung elektrischer Leitfähigkeit eignen sich beispielsweise handelsübliche Leitsalze, leitfähige Polymere sowie verschiedene Produkte auf Basis von Kohlenstoff.The functional layer may be a variety of functionalities, such as an electrically conductive layer, an additional flame retardant layer, and an electrostatic barrier. Likewise, a barrier for organic organisms such. As mites and an antimicrobial functional layer, for example by application of silver or antimicrobial substances are applied. The functional layer is produced by means of the abovementioned polymeric products on the leather or the textile layer. In this case, the dissolved or dispersed functional substances are mixed with the polymeric binder and the coating is applied to commercially available coating systems. Suitable functional substances for achieving electrical conductivity are, for example, commercially available conductive salts, conductive polymers and various products based on carbon.

Die Verstärkung des Leders wird realisiert durch vollflächige oder partielle Verklebung, Vernähung oder Verschweißung mit einem hochfesten und flammhemmenden textilen Materials wie Gewebe, gestrickte und vemadelte Vliese. Beispielsweise jedoch nicht ausschließlich eignen sich textile Flächengebilde bevorzugt aus Glas- sowie Basaltfaser und Carbonfasern, aber auch aus flammhemmenden polymeren Fasern wie Poly-meta und para-Aramide, Modacryl, flammhemmend ausgerüstete Polyester, Polycarbonate und Polyamide. Des weiteren eignen sich auch Polykondensatfaser auf Basis Melamin und analogen Produkten als auch, bis zu einem gewissen Grad, flammhemmend ausgerüstete Naturfasern wie beispielsweise Baumwolle, Leinen, Flachs, Sisal, Hanf, Capok, aber auch Wolle und analoge Tierhaare. Das Textile Material erhöht einerseits deutlich die Reißfestigkeit, insbesondere die Weiterreißfestigkeit des Leders und ermöglich gleichzeitig eine Kosteneinsparung durch die Verwendung noch dünneren Ledern. Besonders hervorzuheben wäre die Gewichtseinsparung des deutlich dünneren Ledermaterials im Automobil – und Flugzeugbereich und der Kostenvorteil durch die Möglichkeit der mehrfachen Spaltung des Rohleders.The reinforcement of the leather is realized by full-surface or partial bonding, sewing or welding with a high-strength and flame-retardant textile material such as woven fabric, knitted and needled nonwovens. For example, but not exclusively, textile fabrics are preferably made of glass and basalt fiber and carbon fibers, but also from flame-retardant polymeric fibers such as poly-meta and para-aramids, modacrylic, flame retardant polyester, polycarbonates and polyamides. Also suitable are polycondensate based on melamine and analog products as well as, to a certain extent, flame retardant treated natural fibers such as cotton, linen, flax, sisal, hemp, capok, but also wool and analogous pet hair. On the one hand, the textile material significantly increases the tear strength, in particular the tear propagation resistance of the leather, and at the same time enables a cost saving through the use of even thinner leathers. Particularly noteworthy would be the weight savings of the much thinner leather material in the automotive and aircraft sector and the cost advantage of the possibility of multiple splitting of the rawhide.

Ein weiteres Problem hinsichtlich des Brandschutzes stellen die Schaumstoffe der Sitzpolster dar. Trotz Flammschutzmittel ist der Flammschutz unzureichend. Im Brandfall besteht die Gefahr, dass sich giftige Zersetzungsprodukte bilden. Die flammhemmende Textile Schicht dient dabei als wirksame Flammschutzbarriere zwischen Sitzpolster und Polsterbezug und reduziert so die Masse brennbarer Substanzen im Innenraum. Im gleichen Maße wirkt eine solche Flammschutzbarriere durch die Verarbeitung mit und in Kombination mit beliebigen Bezugsmaterialien aus textilen Fasern.Another problem in terms of fire protection is the foam of the seat cushion. Despite flame retardants, the flame retardant is insufficient. In case of fire there is a risk that toxic decomposition products will form. The flame-retardant textile layer serves as an effective flame-retardant barrier between the seat cushion and the upholstery cover and thus reduces the mass of combustible substances in the interior. To the same extent, such a flame retardant barrier acts by processing with and in combination with any textile fiber cover materials.
