Die mit Küpenfarbstoffen gefärbten pflanzlichen Fasern zeigen den Übelstand, beim Auskochen mit Natronlauge, Soda usw., wie es für die Zwecke der Bleicherei von Buntgeweben oft erforderlich ist, auszubluten.The vegetable fibers dyed with vat dyes show the problem with Boil with caustic soda, soda, etc., as it is for the purpose of bleaching colored fabrics is often required to bleed out.
Man hat diesem Übelstand in verschiedener Weise abzuhelfen versucht, z. B. durch Zugabe von Permanganat oder von Bichromat zur Bäuchflotte. Wenn hierdurch auch dasAttempts have been made to remedy this deficiency in various ways, e.g. B. by adding from permanganate or from bichromate to the belly liquor. If that too
ίο Ausbluten des Küpenfarbstoffs auf die mitversponnene oder mitverwebte ungefärbte Faser verhindert wurde, so färbte sich letztere doch durch die Metalloxydniederschläge an und mußte durch eine Nachbehandlung mit Säuren wieder weiß gemacht werden.ίο bleeding of the vat dye on the spun or interwoven undyed fiber was prevented, the latter was colored anyway due to the metal oxide deposits and had to be treated with acids to be made white again.
Es wurde nun gefunden, daß ein Zusatz von bromsauren Alkalien zur Bäuchflotte die Wirkung hat, das Ausbluten beim Bäuchen im offenen Übergußkessel wie auch unter Druck zu verhindern und damit die Färbung selbst zu schützen.It has now been found that an addition of bromic acid alkalis to the belly liquor the Has an effect, the bleeding when the stomach in the open over-pouring kettle as well as under Preventing pressure and thus protecting the coloring itself.
Beispiel: Man bereitet eine Bäuchflotte, die 1,2 Prozent festes Ätznatron vom Gewicht des zu bauchenden Stoffes enthält, und setzt dieser Lauge 0,2 bis 0,5 Prozent Kaliumbromat, ebenfalls auf das Gewicht der Ware berechnet, zu.Example: You prepare a belly liquor that is 1.2 percent solid caustic soda by weight of the substance to be bulged, and this lye contains 0.2 to 0.5 percent potassium bromate, also calculated based on the weight of the goods.
Mit dieser Lauge wird die zu behandelnde Ware in der in Bleichereien üblichen Weise zwei oder mehr Stunden offen oder unter Druck gebaucht.With this lye, the goods to be treated are processed in the usual way in bleaching plants two or more hours open or bulged under pressure.
Das in der französischen Patentschrift 392858 beschriebene Verfahren zum Bäuchen von Küpenfarbstoff-Färbungen unter Zusatz reduktionsfähiger Stoffe zwecks Verhinderung des Ausblutens dieser Farbstoffe bedient sich nur bestimmter organischer Körper; demgegenüber beruht das vorliegende Verfahren auf der Verwendung eines bestimmten anorganischen Körpers, der im Gegensatz zu anderen seither versuchten anorganischen Substanzen nicht nur das Ausbluten verhindert, sondern auch den Stoff völlig weiß läßt.The method described in French patent 392858 for bulging Vat dye dyeings with the addition of substances capable of reduction in order to prevent the Bleeding of these dyes makes use of only certain organic bodies; on the other hand the present method is based on the use of a certain inorganic Body, which in contrast to other since then tried inorganic substances not only prevents bleeding, but also leaves the fabric completely white.
