- Patentanspruch:Verfahren zur Herstellung eines Kunstleders, bei dem aus zahlreichen fadenförmigen Verbundfasern mit einer Einbett- und einer Inselkomponente durch Nadeln ein Vliesstoff gebildet, dieser mit einer wasserlöslichen hochpolymeren Substanz imprägniert, die Einbettkomponente durch Behandlung mit ihrem Lösungsmittel aus dem imprägnierten Vliesstoff entfernt wird, wodurch die Bündel der verbleibenden Inselkomponenten aus der Bindung durch die wasserlösliche hochpolymere Substanz befreit werden, der die Bündel der Inselkomponenten entfaltende Vliesstoff mit einer elastischen hochpolymeren Substanz imprägniert und diese verfestigt wird, bei bzw. nach, der Verfestigung aus dem so imprägnierten Vliesstoff die wasserlösliche hochpolymere Substanz entfernt und auf einer Oberfläche des Vliesstoffs eine Schicht aus einer hochpolymeren Substanz gebildet wird, während die andere Oberfläche der Fasergrundschicht gerauht wird, dadurch gekennzeichnet, daß der Vliesstoff nach Entfernen der wasserlöslichen Substanz vor bzw. nach dem Entfernen der Einbettkomponente parallel zur Oberfläche des Vliesstoffs in zwei Stücke geschnitten wird.Die Erfindung betrifft ein Verfahren zur Herstellung eines Kunstleders, bsi dem aus zahlreichen fadenförmigen Verbundfasern mit einer Einbett- und einer Inselkomponente durch Nadeln ein Vliesstoff gebildet, dieser mit einer wasserlöslichen hochpolymeren Substanz imprägniert, die Einbettkomponente durch Behandlung mit ihrem Lösungsmittel aus dem imprägnierten Vliesstoff entfernt wird, wodurch die Bündel der verbleibenden Inselkomponenten aus der Bindung durch die wasserlösliche hochpolymere Substanz befreit werden, der die Bündel der Inselkomponenten enthaltende Vliesstoff mit einer elastischen hochpolymeren Substanz imprägniert und diese verfestigt wird, bei bzw. nach der Verfestigung aus dem so imprägnierten Vliesstoff die wasserlösliche hochpolymere Substanz entfernt und auf einer Oberfläche des Vliesstoffs eine Schicht aus einer hochpolymerenίο Substanz gebildet wird, während die andere Oberfläche der Fasergrundschicht gerauht wird.Bei diesem Verfahren wird aus den Verbundfaden mittels eines Nadelverfahrens ein Vliesstoff gebildet. Dann wird der Vliesstoff mit einer wasserlöslichen hochpolymeren Substanz imprägniert. Danach wird die Einbp.ttkotnponente entfernt, so daß Bündel extrem feiner Fasern (Inselkomponentea^ entstehen, die durch die wasserlösliche Substanz lose miteinander verbunden sind (von Bündel zu Bündel). Danach wird der die Bündel enthaltende Vliesstoff mit einer elastischen hochpolymeren Substanz imprägniert und daraufhin die wasserlösliche Substanz entfernt. Schließlich wird eine Oberfläche der Fasergrundschicht mit einer Schicht aus einer hochpolymeren Substanz bedeckt und die andere Oberfläche beispielsweise mittels Schmirgelpapier gerauht.Es hat sich herausgestellt, daß die Qualität des durch dieses Verfahren hergestellten Kunstleders im Hinblick auf die Gleichmäßigkeit und Feinheit der Rauhup.g noch etwas zu wünschen übrigläßt.Aufgabe dieser Erfindung ist es, die Unterseite des Kunstleders auf einfache Weise mit einer gleichmäßigen, feinen Rauhung zu versehen.Diese Aufgabe wird erfindungsgemäß dadurch gclöst, daß der Vliesstoff nach Entfernen der wasserlöslichen Substanz vor bzw. nach dem Entfernen der Einbettkomponente parallel zur Oberfläche des Vliesstoffs in zwei Stücke geschnitten wird.Es hat sich herausgestellt, daß bei dem darauffolgenden Rauhprozeß der zerschnittenen Fläche ein gleichmäßiger und dichter Flor entsteht.
