   Die Gewinnung der Kautschuklösung kann   in üblicher Weise durch Kneten von reinem Parakautschuk in Solventnaphta in einem geeigneten Behälter geschehen. Es ist jedoch wichtig, dass die Lösung des Kautschuks klar durchsichtig und von der Konsistenz von gelbem Sirup ist. Die Lösung sollte so vollkommen als möglich sein. Aus diesem Grunde ist es wünschenswert, echte   Kautschukiösungsmittei,   wie z. B.   Solventnaphta,   zu benutzen und die Beimischung unerwünschter Kohlenwasserstoffe, wie z. B. Benzin, zu vermeiden. 



  Anstatt Solventnaphta können zur Extraktion der fettigen, öligen und wachsartigen Stoffe aus dem Leder auch andere neutrale Lösungsmittel, welche die Eigenschaft besitzen, auch Kautschuk zu lösen, wie Benzin, Schwefelkohlenstoff und dgl. benutzt werden. Wenn Schwefelkohlenstoff benutzt wird, kann die Extraktion bei dem Siedepunkt dieses Stoffes (46 C) ausgeführt werden. Die Durchführung der Extraktion geschieht dabei zweckmässig

   The rubber solution can be obtained in the usual way by kneading pure para rubber in solvent naphtha in a suitable container. However, it is important that the solution of the rubber is clear, transparent and of the consistency of yellow syrup. The solution should be as perfect as possible. For this reason, it is desirable to use real rubber solvents, such as. B. solvent naphtha to use and the admixture of undesirable hydrocarbons, such as. B. gasoline to avoid.



  Instead of solvent naphtha, other neutral solvents which have the property of also dissolving rubber, such as gasoline, carbon disulfide and the like, can be used to extract the fatty, oily and waxy substances from the leather. If carbon disulfide is used, the extraction can be carried out at the boiling point of this substance (46 C). The extraction is expediently carried out

PATENT-ANSPRUCH : Verfahren zur Zurichtung von Leder durch Einverleibung von Kautschuk in seine Poren nach voraufgegangener Behandlung mit einem Fettlösungsmittel, dadurch gekenn- zeichnet, dass die Imprägnierung mit Kautschuk unmittelbar an die bis zur völligen Entfernung des Fettes getriebene Behandlung angeschlossen wird, wobei zur Entfernung des Fettes und zur Herstellung der Kautschuklösung ein Lösungsmittel benutzt wird, das die Eigenschaft hat, gleichzeitig ein Lösungsmittel für Fett und für Kautschuk zu sein. PATENT CLAIM: Process for finishing leather by incorporating rubber into its pores after previous treatment with a fat solvent, characterized in that the impregnation with rubber is immediately connected to the treatment carried out until the fat is completely removed, with the removal of the fat and for Preparation of the rubber solution is used a solvent that has the property of being a solvent for both fat and rubber.
