Description
Verfahren zum Äsehern von Häuten und Fellen. Durch mehrjährige Beobachtung in einem Gerbereibetriebewurde die Tatsache festge stellt, dass in einem bis zu einem gewissen Grade mit Hautsubstanz angereicherten Ascher, der vor Fäulnis geschützt wird, die eingebrachten Häute keine Hautsubstanz mehr verlieren.
Unter Ausnutzung obiger Feststellung kommt beim Verfahren zum Aschern von Häuten und Fellen, das Gegenstand vorlie gender Erfindung bildet, ein Erdalkali äscher (Erdalkalilauge) zur Anwendung; der mit eiweissartigen Stoffen mindestens so weit angereichert ist, dass sich ein an näherndes Gleichgewicht zwischen diesen Stoffen und dem in der Haut gelöst eritlial- tenen Eilweiss ergibt, so class der Ascher der Haut keine Eiweissstoffe mehr entzieht.
Als Erdalkaliäscher kann Barytlauge oder ein mit einem fäulnishindernden Desinfektions mittel, wie z. B. Kreosot, versetzter Kalk äscher verwendet werden.
Die Anreicherung der Ascher finit. eiweiss artiger Substanz erfolgt praktisch auf bil ligste Weise durch Einbringen von Leim- leger. Hautabfällen, Ohren. Schnauzen oder

Method of sowing hides and skins. Through several years of observation in a tannery, the fact was established that in an ashtray enriched to a certain extent with skin substance, which is protected from rot, the hides no longer lose any skin substance.
Taking advantage of the above finding, an alkaline earth ash (alkaline earth lye) is used in the method for ashing hides and skins, which is the subject matter of the present invention; which is enriched with protein-like substances at least so far that an approaching equilibrium results between these substances and the egg white dissolved in the skin, so that the ashtray no longer removes any protein substances from the skin.
As alkaline earth ash, barite or a medium with a putrefactive disinfectant, such. B. Creosote, offset lime ash can be used.
The enrichment of the ashtrays is finite. Protein-like substance is practically done in the cheapest way by introducing glue layers. Skin debris, ears. Snout or
