Description

mittel zum Einfetten von Leder Durch das Patent 514 399 ist ein Hilfsmittel für die Ledergerberei unter Schutz gestellt, welches aus einer Mischung von Lecithin mit fettem Öl besteht, die zum Einfetten des Leders verwendet wird.means for greasing leather By the patent 514 399 is an aid placed under protection for leather tannery, which consists of a mixture of lecithin with fatty oil, which is used to grease the leather.

Wie nun gefunden wurde, lassen sich aus einem Gemisch von Lecithin (Phosphatiden), Tran und einem dasselbe um ein Mehrfaches überschreitenden Zusatz von Wasser Emulsionen herstellen, die mit besonderem Erfolg für den angegebenen Zweck benutzt werden können.As has now been found, a mixture of lecithin (Phosphatiden), Tran and an additive that exceeds the same by several times of water to produce emulsions with particular success for the specified Purpose can be used.

Man mischt beispielsweise 5 bis io°/o Pflanzenlecithin, das z. B. aus Sojabohnen gewonnen worden ist, mit 9o bis 95°/o Tran, der gegebenenfalls vorher mit Ammoniak neutralisiert wurde. Das Lecithin läßt sich in dem Tran gleichmäßig verteilen, während man das auf diese Weise gewonnene Gemenge in jedem gewünschten Verhältnis mit Wasser mischen kann, um eine dauernde Emulsion zu erzielen, aus welcher sich nachträglich das Öl nicht wieder abscheidet. Um das Ausscheiden der Kalkseifen zu vermeiden, verwendet man zweckmäßig kalkfreies Wasser bei der Herstellung der Emulsion, wie es z. B. als Kondenswasser zur Verfügung steht.For example, 5 to 10% vegetable lecithin is mixed, which z. B. obtained from soybeans, with 90 to 95 ° / o oil, which may have been obtained beforehand neutralized with ammonia. The lecithin settles in the oil evenly distribute while adding the mixture obtained in this way in any desired Ratio can mix with water to achieve a lasting emulsion from which the oil does not separate again afterwards. About the excretion of lime soaps to avoid, it is advisable to use lime-free water in the preparation of the Emulsion, as it is e.g. B. is available as condensation.

Weiterhin kann man so verfahren, daß man eine Mischung verwendet, welche aus i Teil Sojalecithin mit einem Lecithingehalt von 65°/o und 4 Teilen kältebeständigem Tran besteht. Von dieser Mischung finden zum Einfetten des Leders, welche z. B. im Walkfaß bei einer Temperatur von 5o ° C vorgenommen wird, 3°/o Verwendung. Das Lecithin wird unter Erwärmen in dem Tran aufgelöst; hierauf gibt man etwas Ammoniak hinzu und schüttelt kräftig durch, bis sich eine gleichmäßige Emulsion gebildet hat. Alsdann gibt man unter Umrühren allmählich so viel warmes Wasser zu, bis die Flüssigkeitsmenge 200°/o des Falzgewichtes des einzufettenden Leders beträgt. Auf ioo Teile Falzgewicht sind somit o,6 Teile Lecithin, 2,4 Teile Tran und Zoo Teile Wasser erforderlich. In dieser wässerigen Fettemulsion wird z. B. Kalbleder 45 Minuten lang im Walkfaß gewalkt; das Fett ist dann gleichmäßig und vollständig von dem Leder aufgenommen worden.Furthermore, one can proceed in such a way that one uses a mixture which consists of 1 part soy lecithin with a lecithin content of 65% and 4 parts cold-resistant Tran exists. From this mixture find for greasing the leather, which z. B. is carried out in a fulling barrel at a temperature of 50 ° C, 3% use. That Lecithin is dissolved in the oil with heating; a little ammonia is then added and shake vigorously until an even emulsion forms Has. Then gradually add enough warm water, while stirring, until the The amount of liquid is 200% of the shaved weight of the leather to be greased. on 100 parts folding weight are thus 0.6 parts lecithin, 2.4 parts oil and zoo parts Water required. In this aqueous fat emulsion z. B. Calf leather 45 minutes for a long time in a full drum; the fat is then evenly and completely removed from the leather been recorded.

An Stelle von Sojalecithin kann aus Erbsen oder Erbsenschähnehl sowie aus anderen Hülsenfrüchten gewonnenes Lecithin mit dem gleichen Erfolge Verwendung finden. Ebenso eignet sich hierfür durch Extraktion mit Alkohol oder Alkoholbenzol aus Fischrogen gewonnenes tierisches Lecithin, wobei der Rogen durch Behandeln mit Aceton vorher von Wasser und Tran befreit wird und der Tran nachträglich bei der Herstellung der Emulsion von Lecithin, Tran und Wasser wieder Verwendung finden kann.Instead of soy lecithin, peas or pea shavings can be used as well Lecithin obtained from other legumes has been used with the same success Find. Extraction with alcohol or alcohol benzene is also suitable for this Animal lecithin obtained from fish roe, the roe being treated with Acetone is freed from water and oil beforehand and the oil is subsequently removed from the Production of the emulsion of lecithin, oil and water can be used again can.
