Die uns vom Orient überkommenen Kotbeizen spielen in der Lederfabrikation eine wichtige Rolle. Man verwendet hierzu Hundekot, zuweilen auch Tauben- und Hühnermist. Der Zweck dieser Beize besteht nicht nur in der Entfernung des von den Hautblößen während des Äscherprozesses aufgenommenen Kalkes, sondern in erster Linie darin, die stark geschwollenen Felle matt und flach zuThe manure stains handed down to us from the Orient play one role in leather production important role. Dog droppings are used for this, and sometimes pigeon and chicken droppings are also used. The purpose of this stain is not just to remove the skin from the skin lime absorbed during the liming process, but primarily in it, the heavily swollen skins dull and flat too
ίο machen, die in den Hauteinstülpungen zurückgebliebenen Haarböden, Grundhaare, Fett- und Schleimdrüsen zu lösen und die gebildeten Kalkseifen so zu zersetzen, daß eine leichte Entfernung durch das sogenannte Abziehen und Glätten auf mechanischem Wege möglich wird.ίο make the ones left behind in the skin protuberances To dissolve hair bases, basic hair, fat and mucous glands and to decompose the lime soaps so that a light Removal by so-called peeling and smoothing possible by mechanical means will.
Felle, bei denen dieser Zweck nicht erreicht wird, sind untauglich zur Herstellung eines guten Leders, besonders Glaceleders.Skins that fail to achieve this purpose are unsuitable for making one good leather, especially glazed leather.
so Über die Art der Wirkung der Kot-, namentlich der Hundekotbeize kann man heute noch keine erschöpfende Erklärung abgeben. Man schreibt sie tryptischen und proteolytischen Enzymen, in erster Linie dem Pankreastrypsin zu oder auch der Wirkung von Bakterien, und darauf stützen sich einige Verfahren, den Hundekot zu ersetzen. Versuche des Erfinders mit Pankreatin, die schon im Jahre 1893 ausgeführt' wurden, hatten, keinen vollen Erfolg, da eine genügende Lockerung des Grundes nicht erreicht wurde. Dr. Wood, der ebenfalls sehr instruktive Versuche über die Wirkung des Pankreatins ausführte, fand, daß »obwohl Trypsin zu der Wirkung der Hundekotbeize beitragen mag, der Haupteffekt anderen Ursachen zuzuschreiben sei.«so about the nature of the effect of the feces, namely the dog excrement stain cannot be given an exhaustive explanation today. They are written as tryptic and proteolytic Enzymes, primarily to the pancreatic trypsin or the effect of Bacteria, and this is what some methods rely on to replace dog poop. try of the inventor with pancreatin, which had already been carried out in 1893, not a complete success, as a sufficient one Loosening of the reason was not achieved. Dr. Wood, who is also very instructive Experiments on the effect of pancreatin carried out, found that "although trypsin to the Effect of the dog feces stain may contribute to ascribing the main effect to other causes may be."
Erfinder stellte durch Versuche weiter fest, daß filtrierter Hundekot, der doch das Pankreastrypsin gelöst enthält, seine Wirksamkeit fast einbüßt und die volle Beizwirkung erst wieder eintritt, wenn man den Rückstand wieder mit dem Filtrat vereinigt hat.The inventor further established through experiments that filtered dog excrement, which still contains pancreatic trypsin contains dissolved, almost loses its effectiveness and the full pickling effect only occurs again when you remove the residue has reunited with the filtrate.
Eine analoge Beobachtung machten auch Dr. Wood und Dr. Becker:. welche fanden, daß die Reinkulturen von Hundekot sich als wenig wirksam erwiesen und erst zur vollen Wirkung kamen, wenn sie sie mit Kleie, Mehl o. dgl. mischten.Dr. Wood and Dr. Becker :. who found that the pure cultures of dog feces proved to be ineffective and only came to their full effect when they were mixed with bran, flour or the like.
Hieraus ist zu schließen, daß bei der Kotbeize nicht nur Enzyme oder Bakterien, sondern in erster Linie katalytische Erscheinungen, Kontaktwirkungen und Colloidreaktionen eine wichtige Rolle spielen. Da der Erfinder weiter bei der Hundekotbeize das Auftreten von freiem Sauerstoff wie bei der Kleienbeize feststellen konnte, so baute er darauf sein neues Verfahren auf, um Felle und Häute zu entkalken und zu beizen.From this it can be concluded that in the manure dressing not only enzymes or bacteria, but primarily catalytic phenomena, contact effects and colloid reactions to play an important role. Since the inventor continues to stain dog excrement, the occurrence of free oxygen like in the bran pickle, so he built his new one on it Procedure to decalcify and pickle hides and hides.
Die Verwendung von Sauerstoff allein oder Sauerstoff abgebenden Verbindungen führte zu keinem Resultat. Die Blößen wurden rauh und verfielen nicht genügend, auch war eine Lösung des sogenannten Grundes im Felle nicht eingetreten. Sobald aber Sauerstoff zugleich mit schleimgebenden organischen Stoffen zur Anwendung gebracht wurde, ergab sich ein voller Beizeffekt, ja dieser war bei Blößen, die einen starken Äscher aus Auripigment und Kalk erhalten hatten, gün-The use of oxygen alone or oxygen-releasing compounds led to no result. The nakedness became rough and did not deteriorate sufficiently, and there was one too Solution of the so-called reason in the skin did not occur. But as soon as oxygen was brought into use at the same time as slimy organic substances, resulted a full staining effect, yes this was on pelts that had a strong ash from auripigment and had received lime,
