Description

  • Verfahren zur Herstellung von Gegenständen aus kunstlederartigen Materialien Die Erfindung betrifft ein Verfahren zur Herstellung eines kunstlederähnlichen Materials, welches bei der Herstellung von Koffern, Handtaschen usw. Verwendung finden kann0 Es ist bereits bekannt, derartige Produkte aus echten bzw. künstlichem Leder herzustellen, Zu diesem Zwecke mussten die nicht selbst tragenden Leder- und Kunstlederstücke entspreche zugeschnitten werden. Anschliessend wurden die so vorbereiteten Stücke vernäht, verleimt und mitStützteilen versehen.
  • Gemäss der vorliegenden Erfindung wird nun ein Material zur Herstellung derartiger Produkte verwendet, welches durch Pressen zwischen einer Matrize und einer Patrize sofort in die gewünschte Form übergeführt werden kann. Zu diesem Zweck imprägniert man ein Faservlies mit einem vulkanisierbaren oder aushärtbaren Bindemittel. Nach dem Trocknen kann dieses Zwischenmaterial monatelang gelagert werden, ohne dass das im Faservlies nunmehr enthaltene vulkanisierbare oder härtbare Bindemittel in den vulkanisierten oder ausgehärteten Endzustand übergeht. Dies erfolgt erst beim Pressen zwischen einer heissen Matrize und Patrize. Während dieses Heisspressens findet einmal die Formgebung statt und zum anderen die Ausvulkanisation bzw. Aushärtung des Bindemittels. Nach dem Entnehmen aus der Form ist der verformte Gegenstand beständig. Er verliert also seine Form weder beim Lagern noch beim Gebrauch.
  • Als Ausgangsvlies können die verschiedensten Fasern nd Faserkombinationen, die in der Vliesstoffindustrie bereits üblich sind, verwendet werden. Die Fasern sind vorzugsweise so lang, dass sie kardiert werden können0 Mit anderen Worten: Ihre Länge beträt im allgemeinen zwischen 0,4 und 8 cm, vorzugsweise - 6 cm. Die Überführung der Fasern in ein Vlies kann ausser durch Kardieren mit Hilfe des sog. "Rando-Webber" erfolgen, Mehrere Lagen, z.B. 3 - 20, eines Vlieses mit einem Gewicht von 15 - 35 g/m2 werden aufeinanergelegt und zu einem vlies der gewünschten Dicke zusammengepresst. Das Endgweicht beträgt @@@n zwischen 40 und 500 g/m2. Um eine Gleichförmigkeit zu erreichen, werden die einzelnen Lagen in verschiedenen Winkeln aufeinander gelegt. Auf diese Weise wird, falls in einer Lage die Fasern in einer Richtung ausgerichtet sind, im Endprodukt durch Uberlagerung eine gleiche Stärke in allen Richtungen erhalten. Es empfiehlt sich, diese Ausgangsfaservliese zu nadeln, um dadurch ihre Festigkeit und ihren Verbund nochmals zu erhöhen.
  • Diese vorzugsweise genadelten Faservliese werden anschliessend mit üblichen vulkanisierbaren bzw. härtbaren Bindemitteln, wie z,B, Pliolite Latex 460 der Goodyear Tiere & Rubber Company oder Latex QX-3367 der Dow Chemical Company oder Hycar Latex der Goodrich Chemical Company oder Ucar Latex der Union Carbide Corporation imprägnirrt. Das Verhältnis von Faser zu Bindemittel soll ungefähr 1:1 - 1:6 sein. Besonders günstig ist ein Bereich von 1:1 - 1:2,5. Nach dem Imprägnieren, das durch Tauchen oder einer Schaumimprägnierung mit Hilfe von Walzen erfolgen kann, trocknet man die Produkte unter gelinden Bedingungen.
  • Es soll beim Trocknen lediglich das Wasser verdampfen, jedoch noch keine Vulkanisation oder Aushärtung eintreten. Die trockenen Materialien können gerollt werden, ohne dass eine Verklebung stattfindet0 Die Lagerfähigkeit ist in diesem Zustand praktisch unbegrenzt.
  • Will man mit diesem Zwischenmaterial nun Gegenstände herstellen, so muss das Vlies zunächst wieder angewärmt werden, um es möglichst verformbar zu machen. Man legt es anschliessend zwischen eine Matrize und eine Patrize, welche auf beliebiger Temperatur und beliebigen Druck einreguliert werden kann. Im allgemeinen genügt es, die Flächengebilde 3 1/2 Minuten bei einer Temperatur von 1600 zu pressen. Sie sind nach der Entnahme aus der Form beständig. Zur Erhöhung der Pormbeständigkeit kann man die Flächengebilde mit weiteren Stützschichten versehen.
  • Es ist z. B. möglich, ein Versteifungsgewebe zusammen mit dem Zwischenmaterial in die Form einzulegen. Es wird aber in einem Arbeitsgang ein mit einer Stlltzschicht versehener kunstlederartiger Gegenstand erzeugt. Es ist jedoch auch möglich, die Stützschicht nach dem Verformen zwischen Matrize und Patrize aufzukleben.
