Description

Verfahren zum Behandeln von fertig zugerichtetem sämischgarem Leder Verfahren zur überführung von Leder in einen Zustand kautschukartiger Elastizität sind nicht bekanntgeworden. Es hat sich nun gezeigt, daß fertig zugerichtetes sämisch-gares Leder bei Behandlung mit handelsüblichen wäßrigen Lösungen von Zinkchlorid oder Calciumrhodanid einen elastischen Zustand annimmt. Solche Lösungen des Handels werden auf das Leder aufgesprüht, aufgetragen, oder man kann auch das Leder direkt mit der Lösung tränken und dann zweckmäßig den Überschuß abpressen.Process for treating finished, chamois leather Process for converting leather into a state of rubber-like elasticity have not become known. It has now been shown that ready-made chamois-cooked Leather when treated with commercially available aqueous solutions of zinc chloride or Calcium rhodanide assumes an elastic state. Such solutions will be of trade sprayed on the leather, applied, or you can also use the leather directly soak the solution and then expediently squeeze off the excess.

Das Leder zeigt bei dem Behandeln leine gewisse Schrumpfung und nimmt schon nach kurzer Behandlung, insbesondere aber nach erfolgter Trocknung, eine Elastizität an, die ein kautschukartiges Ausziehen ,über die ursprüngliche Länge hinaus gestattet. Obgleich in erster Linie Zinkchlorid geeignet ist, hat es sich ,gezeigt, daß auch z. B. eine etwa 2o- bis q.o%ige Lösung von Calciumrhodanid, wenn auch nicht so gut wie Zinkchlorid, zur Erreichung des elastischen Zustandes benutzt werden kann.The leather shows a certain amount of shrinkage on treatment and increases already after a short treatment, but especially after drying, an elasticity that allows a rubber-like extension beyond the original length. While zinc chloride is primarily suitable, it has been found that too z. B. an about 2o to q.o% solution of calcium rhodanide, although not so good like zinc chloride, can be used to achieve the elastic state.
