Verfahren zur Herstellung von Mochaleder.
Bei der Herstellung von Mochaleder ist es bereits bekannt, die Felle durch starkes Äschern mit Kalk und nachheriges Säuern einer Schnellbehandlung zu unterziehen, wodurch die sonst übliche Behandlungszeit von mehreren Monaten auf eben so viele Wochen herabgedrückt wird.
Gegenstand vorliegender Erfindung ist nun ein weiterhin verbessertes und beschleunigtes Beizverfahren, bei dem die Felle nach vorheriger zweimaliger Kalkäscherung und nachträglicher Waschung in einer verduften Salpetersäurelösung behandelt werden, um eine äusserst beschleunigte Entkä ! kung zu erzielen, worauf die Felle ausgestrichen einer Nachbehandlung mit eine. verdünnten Boraxlösung zwecks vollständiger Entkälkung ausgesetzt worden, so dass die gesamte Behandlungsdauer auf etwa fünf Tage herab- gedrückt wird.
Die zu verarbeitenden Felle werden bei der Behandlung zunächst geweicht und dann

sie eingesetzt in ein entsprechendes Fass, um darin aufgerührt zu werden.
Alsdann werden sie in lauwarmem Wasser und später in kaltem Wasser abgewaschen und auf dem Baum enthaart. Hienach kommen die Häute nochmals für fünf bis sechs Stunden in denselben Äscher, um danach zweimal im Walkfasse gewaschen und be-

von Salpetersäure, z. B. 300 9 Säure auf 100 l Wasser, etwa 30 Minuten lang ans- gesetzt, hinach geläutert und Ausgestrichen, um endlich der Einwirkung einer verdünnten Boraxlösung, 1 kg Borax auf 100 l Wasser bel 200, ausgesetzt zu worden, worauf ein nochmaliges Läutern und Garmachbn erfolgt. Auf diese Weise lassen sich die Felle in zirka fünf Tagen zu einwandfreiem Mocbaleder verarbeiten.

Method of making mocha leather.
In the production of mocha leather, it is already known to subject the skins to a rapid treatment by heavy liming with lime and subsequent acidification, whereby the otherwise usual treatment time is reduced from several months to just as many weeks.
The subject of the present invention is a further improved and accelerated pickling process in which the skins are treated after two previous lime ashes and subsequent washing in an evaporated nitric acid solution in order to achieve an extremely accelerated decaling! kung to achieve, whereupon the skins spread an after-treatment with a. diluted borax solution has been exposed for the purpose of complete deliming, so that the total duration of treatment is reduced to about five days.
The skins to be processed are first softened during the treatment and then
EMI1.1
they are placed in a suitable barrel to be stirred up.
They are then washed in lukewarm water and later in cold water and hair removed on the tree. The hides are then placed in the same liming again for five to six hours, after which they are washed and loaded twice in the drum.
EMI1.2
of nitric acid, e.g. B. 300 9 acid to 100 l of water, set for about 30 minutes, refined and smeared out, in order to finally be exposed to the action of a dilute borax solution, 1 kg of borax per 100 l of water bel 200, whereupon a second purification and Garmachbn takes place. In this way, the skins can be processed into perfect mocha leather in about five days.
