Description
Verfahren zuin Durchfärben von Zeder. Es wurde gefunden, dass es gelingt, Leder, insbesondere Chromleder, vollständig durchzufärben, wenn man dazu den gelben Farbstoff 3-Nitro-3'-ch@or-2',4'-diamino-1,1'- azobenzol-6.6'-disulfonsäure verwendet. Die Oberfläche des Leders wird fahl gelb, das Innere gelborange 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 3-Nitro-3'-chlor-2',4'- diamino - IX- azobenzol - 6,6'- disulfonsäure durch die hohle Achse zugegeben. Im allge meinen genügen 1-2.% des auf das Falz- gewicht berechneten Farbstoffes, um kräf tige Durchfärbungen zu erzielen. Nach 45 Minuten setzt man den Fatliquor zu und be wegt weitere 45 Minuten.
Handelt es sich um sehr schwere Häute, so ist die Färbe dauer entsprechend zu verlängern.
Process for inking through cedar. It has been found that it is possible to dye leather, in particular chrome leather, completely if the yellow dye 3-nitro-3'-ch @ or-2 ', 4'-diamino-1,1'-azobenzene-6.6' -disulfonic acid is used. The surface of the leather turns pale yellow, the interior yellow-orange.
<I> Example: </I> The neutralized skins are mixed with 150-200% water at 65 C in the barrel; the barrel is run and a dissolution of the dye 3-nitro-3'-chloro-2 ', 4'-diamino-IX-azobenzene-6,6'-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 move for another 45 minutes.
If the hides are very heavy, the dyeing time must be extended accordingly.
