Description
Verfahren zum Fetten von Schweinsleder Der Verwendung von Schweinsleder als Sr,'huhoberl-eder steht dessen Großporigkeit als wesentlicher Nachteil entgegen.Process for greasing pigskin The use of pigskin as Sr, 'huhoberl-eder, its large pores are a major disadvantage.
Es wurde nun gefunden, daß man chromgares Schweinsleder in ausgezeichneter Weise als Schuhoberleder verwenden kann, wenn manesmitSalzenhechinelekulareraliphatischer oder cycloaliphatischer Amine oder Ammoniumverbindungen und vorher oder nachher in an sich bekannter Weise mit Fettemulsionen behandelt, die mit anionwirksamen Emulgiermitteln hergestellt sind. Im Gegensatz zu der an sich bekannten Fettung von chromgarem Schweinsleder mit den genannten Fettemulsionen allein erzielt man nach der vorliegenden Erfindung einen wirksamen und dauerhaften Verschluß der Poren und damit eine den an Schuhoberleder zu. stellenden Anforderungen entsprechende Wasserundurühlässigkeit.It has now been found that chromed pigskin can be obtained in excellent Way to use as shoe upper if onees with salt hechinelekulareraliphatic or cycloaliphatic amines or ammonium compounds and before or after treated in a manner known per se with fat emulsions which act with anionic Emulsifiers are made. In contrast to the well-known greasing from pigskin with low chromium content with the fat emulsions mentioned alone is obtained according to the present invention an effective and permanent closure of the pores and thus one of the shoe upper leathers too. corresponding requirements Impermeability to water.
Man verfährt beispielsweise wie folgt: ioo kg chromgare, gefalzte Schweinshäute werden im Walkfaß mit-,einer Emulsion von o,5 kg Helltran in einer Lösung von 1,5 kg eines bis zur Wasserlöslichkeit sulfonierten Türkischrotöls in 3oo 1 Wasser bei 5o bis 6o' 40 Minuten lang gewalkt. Das so behandelte Leder wird ngn in einem zweiten Bad bei 4o' weiterbehandelt, das aus einer Lösung von 3oo g Oktodecylaminacetat in 3oo 1 Wasser besteht. Man walkt das Leder in dieseni Bad 3o bis 4o, Minuten lang und verarbeitet es üi üblicher Weise weiter. Das so erhaltene Leder kann ebenso wie ein übliches Kalb- oder Ziegenleder als Schuhoberleder dienen.The procedure is for example as follows: ioo kg chrome-tanned, folded pig hides are with- in Walkfaß, an emulsion of o.5 kg Helltran in a solution of 1.5 kg of a up to the water sulfonated Türkischrotöls in 3oo 1 water at 5o to 6o '40 Walked for minutes. The so treated leather is NGN further treated in a second bath at 4o ', which consists of a solution of 3oo g Oktodecylaminacetat in 3oo 1 water. The leather is milled in this bath for 30 to 40 minutes and processed in the usual way. The leather obtained in this way can serve as a shoe upper leather, just like a conventional calfskin or goat leather.
Man kann die Behandlung auch in der umgekehrten Reihenfolge vornehmen.The treatment can also be carried out in the reverse order.
An Stelle des Oktodecylaniinacetats können. auch die Acetate oder Formiate anderer hochmolekularer Amine angewandt werden, z. B. von Diodecylaniln, Ok-t#od-ecenylarnin oder Dicyclohexylarnin.Instead of Oktodecylaniinacetats can. also the acetates or Formates of other high molecular weight amines are used, e.g. B. of Diodecylaniln, Ok-t # od-ecenylamine or dicyclohexylamine.
