Description
Verfahren zur Herstellung eines Leder- oder pergamentartigen Werkstoffes Die Erfindung betrifft ein Verfahren zur Herstellung eines Leder- oder pergamentartigen Werkstoffes nach Patent 895 585, bei dem durch an sich bekanntes Verspinnen von. Superpolyamiden im elektrischen Fell gewgn Vliese, insbesondere Wirrvliese, durch Druck und gegebenenfalls Wärme mit oder ohne Zusatz von Quellmitteln zu dem Werkstoff verwalzt oder verpreßt werden.Process for the production of a leather or parchment-like material The invention relates to a method for producing a leather or parchment-like one Material according to patent 895 585, in which by known spinning of. Super polyamides in the electric fur are made of nonwovens, especially random nonwovens Pressure and possibly heat with or without the addition of swelling agents to the material be rolled or pressed.
Es hat sich gezeigt, daß an Stelle von Superpolyamidlösungen auch Lösungen anderer linearer Polymerer zur Herstellung der Vliese durch Verspinnen im elektrischen Feld mit gleichem Erfolg verwendet werden können, z. B. Lösungen von Polyuretanen, Polyestern oder Mischkondensationsprodukten, z. B. solchen, welche neben Diaminen oder Dicarbonsäuren bzw. Amincarbonsäuren auch die Di-Isocyanate und zweiwertige Alkohole enthalten.It has been shown that instead of superpolyamide solutions, too Solutions of other linear polymers for producing the nonwovens by spinning can be used with equal success in the electric field, e.g. B. Solutions of polyurethanes, polyesters or mixed condensation products, e.g. B. those, which in addition to diamines or dicarboxylic acids or amine carboxylic acids, also the di-isocyanates and dihydric alcohols.
Die Verarbeitungsweise ist im übrigen die gleiche wie gemäß Hauptpatent, die Wirrfaservliese können jedoch, wie dies zur Weiterverarbeitung von Wirrfaservliesen aus Superpolyamidlösungen schon vorgeschlagen wurde, vor oder nach dem Verwalzen oder Verpressen mit Lösungen oder Dispersionen von Bindemitteln, z. B. von Polyvinyl- oder Polyacrylsäureverbindungen imprägniert werden.The processing is otherwise the same as according to the main patent, However, the tangled fiber fleeces can, as is the case for the further processing of tangled fiber fleeces from superpolyamide solutions has already been proposed, before or after rolling or pressing with solutions or dispersions of binders, z. B. be impregnated by polyvinyl or polyacrylic acid compounds.
