Verfahren zum Enthaaren und Reinmachen von Häuten und Fellen.
In der Fabrikation von Leder spielt eine Hauptrolle die sogenannte Reinmacharbeit, d. h. die Entfernung der Haare und des Schmutzes aus den Fellen und Häuten. Man erzielt dies gegenwärtig durch den Äscher und die Beize.
Es hat sich gezeigt, dass man beide Arbeiten ersetzen kann, indem man die geweichen Häute und Felle in eine Lösung von Tryptasen, x. B. Pankreastryptase, einlegt. Man unterstützt die Wirkung der Tryptasen zweckmässig durch alkalische Reaktion der Tryptaselösung und kann auch in der Weise arbeiten, dass man die Felle zunächst kurze Zeit in der alkalisch reagierenden Lösung vorbehandelt und dann die Tryptase zusetzt.
Auch kann die Wirkung der Tryptase durch Zusatz von Aminosäuren unterstützt werden Man kann z. B. in der Weise verfahren, dass man die geweichten Häute oder Felle einen Tag in eine 0.5%ige Sodalösung legt und dann die Tryptase zusetzt und etwa einen Tag in dieser Flüssigkeit weiterbphandplt.
Das Verfahren hat verschiedene Vorteile vor dem bisherigen ; es bringt erhebliche Ersparnis an Zeit, da damit in zwei Tagen dasselbe erreicht wird, wie sonst in 12 bis 20 Tagen ; es bringt weiterhin Ersparnis an Arbeit, ferner bessere Qualität der Haare und Wolle, welche während des Äschers sehr geschädigt werden. Das Verfahren bietet ferner bedeutend hygienische Vorteile für die Arbeiter und wesentliche Fortschritte in der für

EMI1.1
Process for dehairing and cleaning hides and skins.
In the manufacture of leather, the so-called cleaning work plays a major role. H. the removal of hair and dirt from the pelts and skins. This is currently achieved by liming and pickling.
It has been shown that both types of work can be replaced by placing the softened hides and pelts in a solution of tryptases, x. B. pancreatic cryptase. The effect of the tryptases is expediently supported by an alkaline reaction of the tryptase solution and it is also possible to work in such a way that the pelts are first pretreated for a short time in the alkaline solution and then the tryptase is added.
The effect of tryptase can also be supported by adding amino acids. For example, proceed in such a way that the soaked hides or pelts are placed in a 0.5% sodium carbonate solution for one day and then the tryptase is added and continued in this liquid for about a day.
The process has several advantages over the previous one; it saves a considerable amount of time, since the same thing can be achieved in two days as otherwise in 12 to 20 days; it also saves work and improves the quality of the hair and wool, which are very damaged during liming. The process also offers significant hygienic advantages for the workers and significant advances in the for
