Description

Kunstleder aus einem oder mehreren Faservliesen und Kautschuk Es ist bereits bekannt, zur Herstellung von Kunstleder .ein Faservlies zu verwenden und dieses mit Kautschuklösung oder Kautschukmilch zu imprägnieren. Die Fasern der bisher verwendeten Vliese sind verfilzt. Sie liegen also vor der Imprägnierung nicht in einer Richtung, sondern werden erst beim Durchleiten zwischen Preßwalzen meinem gewissen Grade gerichtet, so daß man beim fertigen Produkt von einer Hauptfaserrichtung sprechen kann.Artificial leather made of one or more nonwovens and rubber It is already known to use .ein fiber fleece for the production of artificial leather and to impregnate this with rubber solution or rubber milk. The fibers of the so far The fleeces used are matted. So they are not in before the impregnation one direction, but are only mine when passing between press rolls Directed to a certain extent, so that one main fiber direction in the finished product can speak.

Der Erfindung gemäß werden zur Herstellung von Kunstleder ein oder mehrere für sich imprägnierte Faservliese verwendet, deren Fasern im wesentlichen m einer Richtung liegen. Ein solches Faservlies saugt die Kautschuklösung oder Kautschukmilch besser auf als ein Vlies mit verfilzten Fasern, denn an den gleichgerichteten Fasern können sich keine Luftblasen festsetzen, die ein völliges Eindringen der -Lösung in das Vlies verhindern, was sich als nachteilig bei Vliesen mit verfilzten Fasern herausgestellt hat. Außerdem ist die Zugfestigkeit eines Faservlieses mit im wesentlichen gleichgerichteten, durch ]Kautschuk miteinander verbundenen Fasern höher als die eines Vlieses mit verfilzten Fasern. Da nach der Erfindung die Fasern bereits vor der Imprägnierung meiner Richtung liegen, geht das Vlies sehr gut zwischen Preßwalzen hindurch, deren Antriebskraft nicht so groß sein muß wie beim Pressen von verfilzten Faservliesen, deren Fasern durch die Walzen in geringem Maße gerichtet werden, wozu jedoch .eine erhebliche Kraft erforderlich ist.The invention according to a or for the production of artificial leather several individually impregnated fiber webs are used, the fibers of which are essentially m in one direction. Such a fiber fleece sucks the rubber solution or rubber milk better than a fleece with matted fibers, because on the fibers in the same direction no air bubbles can accumulate, which would prevent the solution from penetrating completely Prevent into the fleece, which turns out to be disadvantageous for fleeces with matted fibers has turned out. In addition, the tensile strength of a nonwoven fabric is essential unidirectional fibers interconnected by] rubber higher than that a fleece with matted fibers. Since according to the invention, the fibers already before the impregnation in my direction, the fleece goes very well between press rolls through which the driving force does not have to be as great as when pressing matted ones Nonwovens, the fibers of which are straightened to a small extent by the rollers, for what purpose however. a significant amount of force is required.

Wird zur Imprägnierung Kautschukmilch verwendet, so ist nachher nur das Wasser der Kautschukmilch wegzuschaffen, was keine . Schwierigkeiten bereitet. Das Imprägnierungsprodukt wird durch bekannte Trockenvorrichtungen, z. B. geheizte Zylinder, geführt, wobei das Wasser verdampft. Der Kautschukmilch können vorher Schwefel und Beschleuniger für die Vulkaniserung und ändere Zusätze beigemischt werden. Das Rohprodukt kann also ohne weiteres in an sich bekannter Weise vulkanisieren, falls es gewünscht wird.If rubber milk is used for impregnation, then only afterwards to dispose of the water from the rubber milk, which is not. Causes difficulties. The impregnation product is dried by known drying devices, e.g. B. heated Cylinder, with the water evaporating. The rubber milk can beforehand Added sulfur and accelerators for vulcanization and other additives will. The crude product can therefore easily vulcanize in a manner known per se, if so desired.

Vorteilhaft verwendet man ein Faservlies aus gleichgerichteten, gespritzten Kunstspinnfasern (Kunstseide). Es entsteht hierdurch -ein Produkt von ganz außerordentlicher Festi"keit in der BicchWng,--in der die Fasern liegen, weil diese praktisch unendlich lang gemacht werden können.It is advantageous to use a non-woven fabric made from unidirectional, injected man-made staple fibers (artificial silk). This creates - a product of very extraordinary strength in the bending, - in which the fibers lie, because they can be made practically infinitely long.

Um ein Produkt zu erhalten, das eine erhöhte Dehnbarkeit besitzt, kann man !ein Faservlies verwenden, dessen im wesentlichen gleichgerichtete. Fasern gewellt sind. Die Wellung kann in jeder bekannten Weise, z. B. durch fein geriffelte Walzen, vorgenommen werden. 'Die erhöhte Dehnbarkeit des Vlieses ist ähnlich wie bei einer gewirkten Einlage, bei der sich jedoch die Fäden und somit die Fasern kreuzen. Der Erfindung gemäß kreuzen sich die Fasern nicht, sondern liegen zueinander etwa parallel im Kunstleder. Das Produkt kann zur Herstellung von Treibriemen, Reifen, Schläuchen, Dichtungsmaterial und ähnlichen Gegenständen verwendet werden.To obtain a product that has increased elasticity, you can use a fiber fleece whose essentially unidirectional. Fibers are wavy. The corrugation can be made in any known manner, e.g. B. by finely fluted Rolling, are made. 'The increased elasticity of the fleece is similar to a knitted insert, but with the threads and thus the fibers cross. According to the invention, the fibers do not cross, but lie about parallel to each other in the artificial leather. The product can be used to manufacture drive belts, Tires, tubes, sealing material and similar items can be used.

Man kann natürlich im Kunstleder auch mehrere sich kreuzende, für sich imprägnierte Faservliese anordnen, deren Fasern. in jeder Schicht im wesentlichen gleichgerichtet sind. Auch kann man an Stelle von Kautschuk andere bekannte Bindemittel verwenden.You can of course also use several intersecting ones in artificial leather arrange impregnated nonwovens, their fibers. in each layer essentially are rectified. Other known binders can also be used instead of rubber use.
