Verfahren zur Herstellung eines elastischen, hornartigen Produktes aus tierischen
Hautblössen.
Durch die Patentschrift Nr. 56536 ist bereits ein Verfahren zum Härten und Wasserdichtmachen tierischer Hautblössen bekannt geworden, bei welchen die Hautblössen zuerst gehärtet und hierauf mit einen) entsprechenden Überzug versehen wurden. Dieses Verfahren zeigt aber ausser seiner ziemlichen Kostspieligkeit den Nachteil, dass die hiebei zur Verwendung gelangenden Stoffe, d. i. Amylazetat. Azeton, Zelluloid und die Kautschuklösung, feuergefährlich sind. so dass auch die Verwendung des hergestellten Materials sehr beschränkt ist.
Diese Übelstände werden gemäss vorliegender Erfindung in der Weise behoben, dass
EMI1.1
gehärtet, d. i. gegen Nässe und Feuchtigkeit unempfindlich gemacht und hierauf in ein Bad von mit Wasser verdünnter Salpetersäure getaucht werden.
Es ist bereits bekannt (siehe die Patentschrift Nr. 999), die Haute mit schwachen Formaldehydlösungen zu behandeln, welche je nach dem Gerbgut wechselnde Mengen freier Säure enthalten, doch ergibt diese Häutebehandlung ausschliesslich ein lederartiges Produkt.
EMI1.2
kann nun getrocknet und gestreckt werden und erhält das Ausseben und die Eigenschaften des Hornes.

Process for the production of an elastic, horn-like product from animal
Bare skin.
A method for hardening and waterproofing animal skin pores has already become known through patent specification No. 56536, in which the skin pores are first hardened and then provided with a corresponding coating. However, in addition to its rather expensive nature, this process has the disadvantage that the substances used here, i. i. Amyl acetate. Acetone, celluloid and the rubber solution are flammable. so that the use of the material produced is very limited.
According to the present invention, these deficiencies are remedied in such a way that
EMI1.1
hardened, d. i. Made insensitive to moisture and moisture and then immersed in a bath of nitric acid diluted with water.
It is already known (see patent specification No. 999) to treat the skins with weak formaldehyde solutions which contain varying amounts of free acid depending on the tanned material, but this skin treatment results exclusively in a leather-like product.
EMI1.2
can now be dried and stretched and maintains the appearance and properties of the horn.
