Description
Verfahren zur Herstellung von Handschuhleder. Gegenstand des Hauptpatents ist ein Verfahren zur Herstellung von Handschuhleder ohne Verwendung von Eigelb, bei dem eine glyzerinfreie, alkoholische Lösung, von Fettsäuren verseift, als Ersatz des Eigelbs dient.Process for the production of glove leather. Subject of the main patent is a process for the production of glove leather without the use of egg yolk, in which a glycerine-free, alcoholic solution, saponified by fatty acids, is used as a substitute of the egg yolk.
Weitere Verssuche haben gezeigt, daß das zur Handschuhledererzeugung mitver wendete Kochsalz Neigung zur Ausflockung der kolloiden Lösungen des glyzerinfreien, alkoholischen, fettsauren Ammoniaks zeigt, die das mitv erwendete phosphorsaure Natron nicht ganz beseitigt.Further experiments have shown that the glove leather production table salt also used, tendency to flocculate colloidal solutions of the glycerol-free, alcoholic, fatty acid ammonia shows the phosphoric acid used Soda not completely eliminated.
Da sich aus diesem Grunde zuweilen leichte Auflagerungen von fettsaurem Ammonium auf den Narben der Häute zeigten, die dem leichten Eindringen desselben in die Haut hinderlich wurden, wird nun wie folgt verfahren: Tierisches oder pflanzliches Eiweiß, Kasein oder fettarme Milchprodukte (Milchzucker natürlich ausgeschlossen) werden durch Ammoniak gelöst. Die so erhaltenen Lösungen werden dazu verwendet, die glyzerinfreien, alkoholischen Fettsäuren zu verseifen.Since for this reason there are sometimes slight deposits of fatty acid Ammonium on the scars of the skins showed the easy penetration of the same into the skin, the procedure is as follows: animal or vegetable Protein, casein or low-fat dairy products (lactose excluded, of course) are dissolved by ammonia. The solutions thus obtained are used to to saponify the glycerine-free, alcoholic fatty acids.
Man verwendet auf ioo Gewichtsteile Fettsäure: 6 Gewichtsteile Pflanzen- oder Tiereiweiß und 5o Gewichtsteile Ammoniak (o,96 sp. G.) oder 6 Gewichtsteile Kasein und 5o Gewichtsteile Ammoniak (o,96 sp. G.) oder 8,6 Gewichtsteile Quark und. -,5o .Gewichtsteile Ammoniak (o,96 sp. G.) oder 3o Gewichtsteile Mager- oder Buttermilch und 5o Gewichtsteile Ammoniak (o,96 sp. G.).For every 100 parts by weight of fatty acid: 6 parts by weight of vegetable or animal protein and 50 parts by weight of ammonia (0.96 sp. G.) or 6 parts by weight Casein and 50 parts by weight of ammonia (o.96 sp. G.) or 8.6 parts by weight of quark and. -, 50 parts by weight of ammonia (o, 96 sp. G.) or 3o parts by weight of lean or Buttermilk and 50 parts by weight of ammonia (0.96 sp. G.).
Die auf diese Weise erhaltenen Lösungen genügen zur vollständigen Verseifung der Zoo Gewichtsteile Fettsäure, d. h. zur Herstellung des glyzerinfreien, alkoholhaltigen, fettsauren Ammoniums.The solutions obtained in this way are complete Saponification of the zoo parts by weight of fatty acid, d. H. for the production of the glycerine-free, alcohol-containing, fatty acid ammonium.
Zur Herstellung von reinem fettsaurem Ammonium werden auch 5o Gewichtsteile Salmiakgeist von o-96 sp. G. gebraucht, also die gleiche Menge, wie sie zur Herstellung vorgenannter Lösungen nötig ist.For the production of pure fatty acid ammonium also 50 parts by weight are required Ammonia from o-96 sp. G. used, i.e. the same amount as used for production the aforementioned solutions is necessary.
Das Verfahren ist nun das folgende: Die zu verwendende Fettsäure wird unter leichter Erwärmung in Alkohol gelöst und dann in dünnem Strahl in eine der nach vorerwähnter Art erhaltenen Lösungen unter lebhaftem Umrühren eingegossen, wobei der Verseifungsvorgang sich glatt und vollständig vollzieht.The procedure is now as follows: The fatty acid to be used becomes Dissolve in alcohol while warming slightly and then pour a thin stream into one of the Pour in the solutions obtained in the aforementioned manner while stirring vigorously, the saponification process takes place smoothly and completely.
Die mit diesen glyzerinfreien, alkoholhaltigen Ammoniakseifen erhaltenen kolloiden Lösungen, wie sie zur Herstellung von Handschuhleder Verwendung finden, werden durch Kochsalz nicht mehr ausgeflockt, gleichviel, ob man solche allein oder mit phosphorsaurem Natron zusammen zur Herstellung von Handschuhleder benutzt.The ones obtained with these glycerin-free, alcohol-containing ammonia soaps colloidal solutions, such as those used in the manufacture of glove leather, are no longer flocculated by table salt, regardless of whether you use them alone or Used with sodium phosphate to make glove leather.
