Description
Verfahren zum Durelifärben Fon Leder. Es wurde gefunden, dass es gelingt, Leder, insbesondere Chromleder, vollständig durch zufärben, wenn man dazu den rotvioletten Farbstoff aus diazotierter 5-Diäthylamino-2- amino - 1 - methylbenzol -'3 - sulfonsäure und 8-Amino-l-oxynaphthalin - 3,6 - disülfonsäure verwendet. Oberfläche und Kern des Leder werden rotviolett gefärbt.
<I>Beispiel:</I> Die neutralisierten Felle werden im Fass mit 150 bis --)00% Wasser von<B>65'</B> C ver setzt; das Fass wird laufen gelassen und eine Auflösun',. des Farbstoffes aus diazotierter @i -Diäthylamino - ? - amino-l-methylbenzol- < 3- sulfonsäure und 8-Amino-l-oxynaphthaIin- 8,6-disulfonsäure durch die hohle Achse zu gegeben. Im allgemeinen genügen 1 bis 2 des auf das Falzgewieht berechneten Farb stoffes, um kräftige Durchfärbungen zu er zielen.
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 ver längern.
Process for Dureli coloring Fon leather. It has been found that leather, in particular chrome leather, can be completely colored by adding the red-violet dye of diazotized 5-diethylamino-2-amino-1-methylbenzene-3-sulfonic acid and 8-amino-1-oxynaphthalene - 3,6 - disulfonic acid used. The surface and core of the leather are colored red-violet.
<I> Example: </I> The neutralized skins are put in a barrel with 150 to -) 00% water of <B> 65 '</B> C; the barrel is run and a dissolution. of the dye from diazotized @i -diethylamino -? - Amino-1-methylbenzene- <3-sulfonic acid and 8-amino-1-oxynaphthaIin- 8,6-disulfonic acid added through the hollow axis. In general, 1 to 2 of the dye calculated on the folding weight are 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.
