Verfahren zum Beizen und Entkälken von Hautblössen und Leimieder.
Es hat sich gezeigt, dass die bisher für keinen industriellen Zweck verwendbare, bei der Fabrikation der Weinsäure aus Weinhefe und Weinstein von der Fällung des wein. sauren Kalkes resultierende Chlorkalium sowie Chlorkalzium, ferner Pentosen, stickstoffhaltige und andere organische Substanzen enthaltende Ablauge sich in ausgezeichneter Weise zum Beizen der Blössen in der Lederindustrie eignet. Die mit dieser Lauge durch- gefthrten Beizversuche haben ergeben, dass die Haut sehr schön verfällt und eine äusserst zarte Narbe erhält, ohne dass die Hautsubstanz geschädigt wird. Es ist sehr wahrscheinlich,
EMI1.1
auf die Haut in erster Linie hervorgerufen wird.
Weiters wirkt günstig der Gehalt an Pentose, welcher das Entkalken der Haut beschleunigt ; diese günstige Wirkung konnte bei nach verschiedenen Fabrikationsarten gewonnenen Ablaugen des weinsauren Kalkes von der Weinsäurefabrikation beobachtet worden. Das Chlorkalzium und Chlprkalium wirkt

an weinsauren Salzen wirkt bei dem nachfolgendem Gerbprozess sehr fördernd.

Process for pickling and deliming skin pores and glue.
It has been shown that the previously usable for no industrial purpose in the manufacture of tartaric acid from wine yeast and tartar from the precipitation of the wine. Calcium chloride resulting from acid lime and calcium chloride, also pentoses, waste liquor containing nitrogen and other organic substances, are excellently suited for pickling pelts in the leather industry. The staining tests carried out with this lye have shown that the skin decays beautifully and receives an extremely delicate scar without damaging the skin substance. It is very likely
EMI1.1
on the skin in the first place.
The pentose content, which accelerates the decalcification of the skin, also has a beneficial effect; This beneficial effect could be observed in the leaching of the tartaric acid lime obtained by various types of production. The calcium chloride and potassium chloride work
EMI1.2
tartaric salts have a very beneficial effect on the subsequent tanning process.
