Description
Verfahren zum Durchfärben von Zeder. Es wurde gefunden, dass es gelingt, Leder, insbesondere Chromleder, vollständig durch zufärben, wenn man dazu den blauen Farb stoff aus diazotierter 5-Diäthylamino-2- aminobenzol-l-sulfonsäure und 8-Amino-l- oxynaphthalin-3,6-disulfonsäure verwendet. Die Oberfläche des Leders wird blau, das Innere tiefblau gefärbt.
<I>Beispiel:</I> Die neutralisierten Felle werden im Fass mit 150 bis<B>':)00%</B> Wasser von 65 C ver setzt; das Fass wird laufen gelassen und eine Auflösung des Farbstoffes aus diazotierter 5 - Diäthylamino -2 -aminobenzol-l-sulf onsäure und 8-Amino-l-oxynaphthalin-3,6-disulfon- säure durch die hohle Achse zugegeben. Im allgemeinen genügen 1 bis 2'% des auf das Falzgewicht berechneten Farbstoffes, um kräftige Durchfärbungen zu erzielen.
Nach .15 Minuten setzt man .den Fatliquor zu und bewegt weitere 45 Minuten. Handelt es sich um sehr schwere Häute, so ist die Färbe dauer entsprechend zu verlängern.
Method of dyeing cedar. It has been found that it is possible to dye leather, especially chrome leather, completely if you add the blue dye from diazotized 5-diethylamino-2-aminobenzene-1-sulfonic acid and 8-amino-l-oxynaphthalene-3,6- disulfonic acid used. The surface of the leather is colored blue, the inside is deep blue.
<I> Example: </I> The neutralized skins are put in a barrel with 150 to <B> ':) 00% </B> water at 65 C; the barrel is allowed to run and a solution of the dye from diazotized 5-diethylamino -2-aminobenzene-1-sulfonic acid and 8-amino-1-oxynaphthalene-3,6-disulfonic acid is added through the hollow axis. In general, 1 to 2% of the dye calculated on the shaved weight is sufficient to achieve strong through-coloring.
After 15 minutes, add the fat liquor and stir for another 45 minutes. If the hides are very heavy, the dyeing time must be extended accordingly.
