Description
Verfahren zum Durchfärben von Zeder. Es wurde gefunden, dass es gelingt, Leder, insbesondere Chromleder, vollständig durchzufärben, wenn man dazu den bordeaux roten Farbstoff 4-Nitro-4'-diäthylamino-l,l'- azobenzol-2,6'-disulfonsäure verwendet. Die Oberfläche des Leders wird bordeauxrot, das Innere tief bordeauxrot gefärbt.
<I>Beispiel:</I> Die neutralisierten Felle werden im Fass mit 150-200% Wasser von 65 C versetzt; das Fass wird laufen gelassen und eine Auf lösung des Farbstoffes 4-@Titro-4'-diäthyl- amino-1,1'-azobenzol-2,6'-disulfonsäure durch die hohle Achse zugegeben. Im allgemeinen genügen 1.-2% des auf das Falzgewicht berechneten Farbstoffes, um kräftige Durch färbungen zu erzielen. Nach 45 Minuten setzt man den Fatliquor zu und bewegt weitere 45 Minuten. Handelt es sich um sehr schwere Häute, so ist die Färbedauer entsprechend zu verlängern.
Method of dyeing cedar. It has been found that it is possible to dye leather, in particular chrome leather, completely if the burgundy red dye 4-nitro-4'-diethylamino-l, l'-azobenzene-2,6'-disulfonic acid is used for this purpose. The surface of the leather is colored burgundy, the inside is deep burgundy.
<I> Example: </I> The neutralized skins are mixed with 150-200% water at 65 C in the barrel; the barrel is run and a solution of the dye 4- @ Titro-4'-diethylamino-1,1'-azobenzene-2,6'-disulfonic acid is added through the hollow axis. In general, 1.-2% of the dye calculated on the shaved weight is sufficient to achieve strong through-coloring. After 45 minutes, add the fat liquor and stir for another 45 minutes. If the hides are very heavy, the dyeing time must be extended accordingly.
