  Verfahren zur Herstellung von mineralisch, insbesondere chromgegerbtem Sohlen- und dgl. Leder. 



   Als Sohlen-und dgl. Leder für Strapazschuhe wurde bisher ausschliesslich vegetabilisch gegerbtes Leder verwendet. Chromgegerbtes bzw. mineralisch gegerbtes Leder ist als Sohlenleder für Strapazschuhe ungeeignet und alle Versuche, die bisher unternommen wurden, um aus mineralisch bzw. chromgegerbtem Leder einen gleichwertigen Ersatz für vegetabilisch gegerbtes Sohlenleder zu machen, haben zu keinem Ergebnis geführt. Gegenstand der Erfindung ist nun ein Verfahren, durch welches chromgegerbtes bzw. mineralisch gegerbtes Leder als Sohlen-und dgL Leder geeignet gemacht und zu einem gleichwertigen Ersatz für das vegetabilisch gegerbte Leder ausgebildet wird. Die Erfindung besteht darin, dass chromgegerbtes bzw. mineralisch gegerbtes Leder einem Äscherprozess unterworfen wird. 



  Die Erfindung beruht nämlich auf der Feststellung, dass mineralisch bzw. chromgegerbtes Leder bei Behandlung mit Kalkmilch oder dgl. die Eigenschaften eines guten vegetabilisch gegerbte Sohlenleders in erhöhtem Masse erhält und insbesondere gegen Feuchtigkeit und Kälte widerstandsfähiger und fester wird und an Schlüpfrigkeit verliert, sowie auch gegenüber vegetabilisch gegerbtem Leder gleicher Stärke eine höhere Gebrauchsdauer aufweist. 



   Das Verfahren gemäss der Erfindung kann in der Weise ausgeführt werden, dass das in üblicher Weise chromgegerbte Leder geäschert wird. Für die Äscherung ist eine Zeit- dauer von ungefähr zwei bis drei Tagen ausreichend. 



   Gegebenenfalls kann das Leder vor oder zweckmässiger nach der   Äscherung   noch einem Imprägnierungsverfahren zur Erhöhung der Wasserdichtheit unterworfen werden. 



   Ein chromgegerbtes Leder dieser Art ist auch für Dichtungen und dgl. technische
Verwendung vorzüglich geeignet.

  Process for the production of mineral, in particular chrome-tanned soles and similar leather.



   So far, exclusively vegetable-tanned leather has been used as sole and similar leather for hard-wearing shoes. Chrome-tanned or mineral-tanned leather is unsuitable as sole leather for hard-wearing shoes and all attempts that have been made to make an equivalent substitute for vegetable-tanned sole leather from mineral or chrome-tanned leather have not led to any result. The subject matter of the invention is a method by which chrome-tanned or mineral-tanned leather is made suitable as sole and other leather and is made into an equivalent substitute for the vegetable-tanned leather. The invention consists in that chrome-tanned or mineral-tanned leather is subjected to a liming process.



  The invention is based on the finding that mineral or chrome-tanned leather, when treated with milk of lime or the like, has the properties of a good vegetable-tanned sole leather to a greater extent and, in particular, becomes more resistant and firm to moisture and cold and loses its slipperiness, as well as to Vegetable tanned leather of the same thickness has a longer useful life.



   The method according to the invention can be carried out in such a way that the conventionally chrome-tanned leather is ashed. A period of approximately two to three days is sufficient for the liming.



   If necessary, the leather can be subjected to an impregnation process to increase the water tightness before or more appropriately after the liming.



   A chrome-tanned leather of this type is also used for seals and the like. Technical
Excellent use.
