Abstract

Die Erfindung betrifft eine Methode zur Behandlung von Tierhäuten, bestehend aus:
- der Behandlung der Tierhäute mit einem Phenolgruppen enthaltenden Gerbstoff zur Ermöglichung einer Reaktion zwischen dem Hydroxylgruppen (OH-) mit den Alu-lonen einerseits zur Alu-lonen Komplexbildung und Wasserstoffbruckenbildung (nebenvalensig) an die verschiedenen Seitenketten der Polypeptidketten der Haut. Der Bindung Alu-lonen hauptvalentig an die Carboxylgruppen der Polypeptidketten der Haut, mit dem Ergebnis einer irreversible Gerbung, ähnlich der Chromgerbung.

dadurch gekennzeichnet,
dass die Aluminiumbehandlung wenigstens teilweise nach der Fettbehandlung durchgeführt wird.
