KAISERLICHESIMPERIAL
PATENTAMTPATENT OFFICE
Die vorliegende Erfindung besteht in einer neuen Methode bezw. einem neuen Verfahren zum Gerben von Häuten und bezieht sich auf jene Operationen, welche nach dem Behandeln der Häute mit gelöschtem Kalk und dem Entfernen der Haare stattfinden.The present invention consists in a new method BEZW. a new process for tanning hides and refers to those operations that are carried out after treating the skins with slaked lime and hair removal take place.
Seit langer Zeit ist es bekannt, dafs Eisenvitriol Leder gerbt, aber das bisher in dieser Weise gegerbte Leder entsprach nicht den gewünschten Anforderungen und ist deshalb nicht in Aufnahme gekommen.It has been known for a long time that iron vitriol tans leather, but so far in this one Wisely tanned leather did not meet the desired requirements and is therefore not got into admission.
Die vorliegende Erfindung bezweckt nun die Herstellung eines Leders von besserer Qualität, das mittelst Eisenvitriol gegerbt ist.The present invention now aims to produce a leather of better quality, which is tanned by means of iron vitriol.
Das Verfahren ist folgendes:The procedure is as follows:
Nachdem die Häute vorher mit Kalk behandelt und entweder in gewöhnlicher Weise wie zum Gerben durch Eichenborke durch Schwitzen oder Behandlung mit Schwefelnatrium u. s. w. enthaart sind, werden sie in ein Bad von kohlensaurem Eisenoxydul gelegt, in welchem sie ungefähr zwei Tage bleiben, während welcher Zeit sie zuweilen bewegt werden.Having previously treated the skins with lime and either in an ordinary way like for tanning through oak bark by sweating or treatment with sodium sulphide and so on. are depilated, they are placed in a bath of carbonate of iron oxide, in which they remain for about two days, during which time they are sometimes moved.
Zu diesem Bade wird vom Erfinder schwefelsaures Eisenoxydul und Soda, in Wasser gelöst, benutzt. Die Beschaffenheit des Wassers ist dabei nebensächlich, ebenso die Quantität im Verhältnifs zu den benutzten Chemikalien. Selbst mit Kohlensäure gesättigtes Wasser löst das Carbonat nur in geringen Mengen, und mufs deshalb darauf geachtet werden, dafs sich in dem Bassin oder Bottich stets überschüssiges, nicht gelöstes kohlensaures Eisenoxydul befindet, damit die Lösung stets gesättigt ist.For this bath the inventor uses sulfuric acid iron oxide and soda, dissolved in water, used. The nature of the water is irrelevant, as is the quantity in the water Relation to the chemicals used. Even water saturated with carbonic acid dissolves the carbonate only in small quantities, and care must therefore be taken to ensure that it diffuses itself there is always excess, undissolved carbonate of iron oxide in the basin or vat, so that the solution is always saturated.
Wenn kohlensaures Quellwasser benutzt wird, das in der Regel die Kohlensäure in grofsen Mengen gelöst enthält, so nimmt man am zweck mäfsigsten 5 kg Eisenvitriol und 5 kg Soda pro 100 1 Wasser.If carbonated spring water is used, the carbonic acid is usually greater Contains dissolved quantities, the most convenient solution is 5 kg of iron vitriol and 5 kg of soda per 100 liters of water.
Aufserdem setzt man vortheilhaft etwas Schwefelsäure hinzu, damit das Wasser mit Kohlensäure gesättigt wird.It is also advantageous to add a little sulfuric acid to keep the water with it Carbonic acid becomes saturated.
Wenn Wasser benutzt wird, das nur geringe Mengen freier Kohlensäure enthält, benutzt man ein Bad aus 5 kg Eisenvitriol und 3 x/2 kg doppeltkohlensaurem Natron pro 100 1 Wasser. Dieser Flüssigkeit kann man Zucker zusetzen, und zwar auf je 1 kg Eisenvitriol Y2 kg Zucker. Der Zweck des Zuckers ist, eine Verwandlung des Eisenoxyduls in Eisenoxyd zu verhindern. Die Anwendung einer zuckerhaltigen Masse ist aber für den Procefs nicht wesentlich.If water is used that contains only small amounts of free carbon dioxide, a bath of 5 kg of iron vitriol and 3 x / 2 kg of bicarbonate of soda per 100 liters of water is used. Sugar can be added to this liquid, namely 2 kg of sugar for every 1 kg of iron vitriol Y. The purpose of sugar is to prevent the iron oxide from turning into iron oxide. The use of a sugary mass is not essential for the process.
Bei beständigem Gebrauch desselben Bottichs wird, wenn schwefelsaures Eisenoxydul und kohlensaures Natron verwendet wird, die Flüssigkeit bald mit schwefelsaurem Natron übersättigt, und ist es daher wünschenswerth, dafs die Flüssigkeit sich von Zeit zu Zeit setzen kann, damit man den klaren Theil derselben, der schwefelsaures Natron in gelöstem Zustande enthält, ablaufen lassen und auf das am Boden des Bottichs zurückgebliebene kohlensaure Eisenoxydul frisches Wasser giefsen kann. Dann setzt man, um ein Aufbrausen hervorzurufen, genügend Schwefelsäure hinzu und wiederholt dieses ungefähr jeden zweiten Tag, damit stets etwas Kohlensäure frei wird. Man mufs aber darauf achten, dafs man nicht zu viel oder zu häufig Schwefelsäure hinzusetzt, damit man nicht alle Kohlensäure des Carbonats heraustreibt. Die Flüssigkeit mufs aber stets mit Kohlensäure gesättigt sein.With constant use of the same vat, if sulphate of iron oxide and Carbonate of soda is used, the liquid soon with sulfuric acid soda is supersaturated, and it is therefore desirable that the liquid should become from time to time so that one can set the clear part of it, the sodium sulphate in solution Contains states, let them run off and put them on what was left at the bottom of the vat carbonic iron oxide can pour fresh water. Then you put on a flare add enough sulfuric acid and repeat this about every time second day, so that there is always some carbonic acid released. One must, however, make sure that this is the case you don't add too much or too often sulfuric acid so that you don't get all the carbon dioxide of the carbonate. The liquid must always be saturated with carbonic acid.
