Verfahren, die Wolle oder die Haare beim Anschwöden der Felle gegen schädliche
Einflüsse zu schützen.
Die durch Enthaarungsmittel von den Fellen nach bekannten Verfahren abgetrennte Wolle hat einen viel geringeren Verkaufs- und Verwendnngswert als die Wolle, die durch das Schwitzverfahren gewonnen wird ; diesem allerdings haftet der Nachteil an, dass die Häute angegriffen werden. Die Schwächung der Wolle und ihr mattes Aussehen nach dem Anschwöden rühren von der Durchtränkung durch die angewendeten Enthaarungsmittel her, denn diese letzteren dringen durch die Haut und steigen durch Kapillarität in die Haare, wie in gewissen Verfahren, bei denen die Felle vor dem Anschwöden mit einer Schicht von Natriumsulfat überzogen werden.
Die Haare oder die Wolle werden durch die Behandlung mit einem Neutralsalz mürbe, sie verlieren an Elastizität und nehmen ein stumpfes Aussehen an. Wenn man dieses Verfahren zur Zubereitung von Fellen für die Huterzeugung anwendet, zeigt sich ein vollständiger Mangel an Form-und Widerstandsvermögen, und die so erhaltenen Produkte sind vielfach Fehlresultate.
Der Zweck des vorliegenden Verfahrens ist, den Angriff der Haare im Verlaufe des Anschwödens durch die Enthaarungsmittel hintanzuhalten, welch letztere bekanntlich eine alkalische Reaktion aufweisen.
Die Einwirkung der Enthaarungsmittel auf die Haare vermeidet man durch Tränkung der Haare mit einer schwach angesäuerten Lösung, die den Zweck hat, das Schwödemittel zu neutralisieren, wenn

Die vom angesäuerten Wasser durchtränkt Haut ist leicht durchgängig für die Enthaarungsmittel nach Neutralisation durch den Kalk, das Haar jedoch bzw. die Wolle behalten eine verhältnismässig grössere Menge angesäuerten Wassers zurück und sind daher nicht mehr fähig, durch Kapillarwirkung Flüssigkeit aufzunehmen.
Sie behalten auf diese Art ihren Glanz und ihre Festigkeit.

Procedure that the wool or the hair when swelling the pelt against harmful
Protect influences.
The wool separated from the skins by depilatory means according to known processes has a much lower sales and use value than the wool obtained by the sweating process; this, however, has the disadvantage that the skins are attacked. The weakening of the wool and its dull appearance after swelling are due to the impregnation of the depilatory agents used, because the latter penetrate the skin and rise through capillarity into the hair, as in certain processes in which the pelts with a hair before swelling Layer to be coated by sodium sulfate.
Treatment with a neutral salt causes hair or wool to become brittle, it loses its elasticity and takes on a dull appearance. If this method is used to prepare pelts for hat production, there is a complete lack of shape and resistance, and the products thus obtained are often false results.
The purpose of the present method is to prevent the hair from being attacked in the course of the depilatory process, which is known to have an alkaline reaction.
The action of the depilatory agent on the hair is avoided by soaking the hair with a weakly acidified solution, which has the purpose of neutralizing the swelling agent, if
EMI1.1
the skins, skin against skin, by separating each pair from the neighboring pairs by an impermeable fabric, so that the skins are protected against the harmful influence of the swelling agent of the other skins. The skin soaked in the acidified water is easily permeable to the depilatory after neutralization by the lime, but the hair or the wool retain a relatively large amount of acidified water and are therefore no longer able to absorb liquid through capillary action.
In this way they keep their shine and firmness.
