Description

Verfahren zur Erzielung einer künstlichen Narbung auf der Oberfläche von Kautschukkunstleder Bekanntlich besteht Leder aus gegerbter Haut, deren Oberfläche, die sogenannte Narbe, dichter und zusammenhängender als. die darunterliegende Lederhaut ist. Bei einem Stück Leder ist es die Narbe, die das schöne Aussehen der Oberfläche bedingt. In gewissen Fällen preßt man in Leder, besonders in Lederspalte, eine künstliche Narbe ein, um dadurch zu erreichen, das billigeres Leder das Aussehen eines teueren erhält. Eine eingepreßte Narbe kann aber nie die Narbung des natürlichen Leders ersetzen, da die eingepreßte Narbe nur als eine rein äußere Formgebung der Oberfläche bezeichnet werden kann, während eine natürliche Narbe mehr oder weniger tief im Leder sitzt und dessen äußerste Schicht bildet.Process for creating an artificial grain on the surface of synthetic rubber leather It is well known that leather consists of tanned skin, the surface of which the so-called scar, denser and coherent than. the underlying dermis is. On a piece of leather, it is the grain that gives the surface its beautiful appearance conditional. In certain cases an artificial one is pressed into leather, especially into leather crevices Scar to make the cheaper leather look like an expensive one receives. A pressed-in grain, however, can never be the same as the grain of natural leather replace, since the pressed-in scar is only a purely external form of the surface can be referred to as a natural scar more or less deep in the Leather sits and forms its outermost layer.

Der Zweck der vorliegenden Erfindung ist, Kunstleder aus Kautschuk in Verbindung mit . anderen Stoffen herzustellen und mit einer Oberfläche zu versehen, die durch ihr dichteres Gefüge in hohem Grade dem natürlichen Narben des ungespaltenen Leders ähnlich wird. Ein Kunstleder, das mit einer solchen dichteren Oberflächenschicht versehen ist oder = wenn man das vorzieht -'eine wirkliche Narbe besitzt, kann in weit höherem Grad als die bisher bekannten Arten von Kunstleder als Ersatz für Naturleder benutzt werden, indem die Narbe dichter und undurchdringlicher für Feuchtigkeit als die unteren Schichten des Kunstleders ist. Gleichzeitig gibt die Narbe dem Kunstleder ein ähnliches Aussehen und einen. ähnlichen Narbenbruch wie Naturleder.The purpose of the present invention is to make synthetic leather from rubber combined with . to manufacture other materials and to provide them with a surface, which, due to their denser structure, are in a high degree to the natural stigma of the unsplit Leather becomes similar. An artificial leather with such a denser surface layer is provided or = if one prefers that - 'has a real scar, in to a far higher degree than the previously known types of artificial leather as a substitute for natural leather used by making the scar denser and more impervious to moisture than is the lower layers of synthetic leather. At the same time, the grain gives the artificial leather a similar look and one. similar grain hernia as natural leather.

Um Kunstleder, @ das z. B. aus einem Gemisch von Kautschuk und Lederfasern mit einem Zusatz von verschiedenen Zusatzstoffen besteht und nach der Mischung vulkanisiert ist, mit einer. nachgeahmten Naturnarbe zu versehen, verährt man erfindungsgemäß derart, daß man vor der eigentlichen Vulkanisierung des Kunst- oder Kautschukkunstleders dessen Oberfläche mit einem Schwefelvulkanisation in der Kälte bewirkenden Stoff bestreicht oder auf andere Weise diesen Stoff auf die Oberfläche des Kautschukkunstleders einwirken läßt. Solche Vulkanisiermittel sind z. B. Chlorschwefel oder Pentametlh'ylen, dithiocarbarninsaures Piperidin. Durch diese Behandlung wird die Außenfläche des Kautschukkunstleders ' fester und steifer als die darunterliegende Masse, so daß man dadurch das sonst nur beim Leder bekannte Narbenbild erhält. Nach erfolgter kalter Oberflächenvulkanisierung. wird die Kautschukmischung der gewöhnlichen Warmvülkanisierung mit dem Ergebnis unterworfen, daß seine Oberfläche ihre Glätte und Dichtheit bewahrt, indem alle Faserteilchen in der' äußersten Schicht selbst in ähnlicher Weise wie die Fasern in def Narbe im natürlichen Leder festgebunden sind.To artificial leather, @ the z. B. from a mixture of rubber and leather fibers with an addition of various additives and vulcanized after mixing is, with a. To provide imitated natural grain, one proceeds according to the invention in such a way that before the actual vulcanization of the synthetic or synthetic rubber leather its surface with a substance that vulcanizes sulfur in the cold brushes or in some other way this material on the surface of the rubber synthetic leather can act. Such vulcanizing agents are e.g. B. chlorosulfur or pentamethylene, dithiocarbaric acid piperidine. With this treatment, the outer surface of the Synthetic rubber leather is stronger and stiffer than the mass underneath, so that you get the grain pattern that is otherwise only known from leather. After cold surface vulcanization. becomes the rubber compound of the usual hot vulcanization subject with the result that its surface retains its smoothness and impermeability, putting all fiber particles in the 'outermost layer itself in a similar manner as The fibers are tied in the def grain in the natural leather.

Erfindungsgemäß hergestelltes Kautschukkunstleder ist Naturleder ähnlich und ist deshalb in hohem Grade zur Verwendung als Oberleder und für Reiseeffekten sowie als Leder zur Herstellung von Bekleidungsgegenständen geeignet. Außer mit der nachgeahmten Naturnarbe kann das Kunstleder in bekannter Weise mit einem künstlichen Narben durch Pressen versehen werden. Benutzt man als Ausgangsstoff ein Gemisch von Kautschuk und tierischen oder Pflanzenfasern, versieht solches Leder mit einer künstlichen Narbe und preßt man ihm außerdem noch eine Narbe auf, so erhält man ein Erzeugnis, das äußerlich in hohem Grade Leder ähnlich sieht.Synthetic rubber leather produced according to the invention is similar to natural leather and is therefore highly suitable for use as a Upper leather and suitable for travel effects as well as leather for the manufacture of clothing items. In addition to the imitated natural grain, the artificial leather can be used in a known manner an artificial scar can be provided by pressing. Used as a raw material a mixture of rubber and animal or vegetable fibers provides such leather with an artificial scar and if you also press a scar on it, this is how it is obtained a product that looks very similar to leather on the outside.
