Patentiert im Deutschen Reiche vom 14. Dezember 1913 ab.Patented in the German Empire on December 14, 1913.
Es ist bekannt, daß die Reib- und Schabechtheit mit Indigo gefärbter Wollwaren dadurch erhöht werden kann, daß man die Wolle vor dem Färben. mit Metallsalzen, im besonderen mit Chromsalzen, beizt.It is known that the resistance to rubbing and scraping of woolen goods dyed with indigo can be increased by removing the wool before dyeing. pickles with metal salts, especially with chromium salts.
Ferner ist die Herstellung von Wollmelangen bekannt, bei denen die helle Melierwolle mit ' Chrom- und Kupfersalzen zur Erzielung einer besseren Lichtechtheit vorgefärbt ist.Furthermore, the production of wool melanges is known, in which the light melange wool with 'Chromium and copper salts are pre-colored to achieve better lightfastness.
ίο Während man früher nur Indigo als Küpenfarbstoff kannte, sind in den letzten Jahren eine ganze Reihe neuer Küpenfarbstoffe hergestellt worden, die wegen ihrer hervorragenden Echtheitseigenschaften dem Indigo ohne weiteres zur Seite gestellt werden können.ίο While one used to only use indigo as a vat dye a whole range of new vat dyes have been produced in recent years which, because of their excellent fastness properties, can easily be placed alongside the indigo.
Bei dem bekannten Waschverfahren für Schafwolle mit Seife und Soda erzielt man eine Reinigung, die je nach dem Ursprung •und der Natur der Wolle zum Färben mit Küpenfarbstoffen noch nicht genügt. Es ergeben sich hieraus teils ungleichmäßige Färbungen, teils starkes Nachlassen der Färbungen während der Fabrikation. Am meisten zeigen sich diese Übelstände aber erst beim Tragen der Stoffe.In the known washing process for sheep's wool with soap and soda one achieves a cleaning which, depending on the origin • and the nature of the wool to be dyed with Vat dyes are not enough. This sometimes results in uneven colors, partly strong weakening of the color during manufacture. The most However, these inconveniences only show up when the fabrics are worn.
Wird die Wollfaser aber vor dem Färben mit Küpenfarbstoffen (außer Indigo) mit chromsauren oder doppeltchromsauren Salzen behandelt, so tritt hierdurch eine nochmalige ganz energische Reinigung der Wollfaser ein. Die Farbstoffe dringen beim Ausfärben besser in das Innere ein, und die Färbungen werden natürlich widerstandsfähiger gegen atmosphärische und mechanische Einflüsse.However, if the wool fiber is dyed with vat dyes (except indigo) with chromic acid or double chromate treated salts, a repeated whole occurs hereby vigorous cleaning of the wool fiber. The dyes penetrate better when they are colored the interior, and the colors naturally become more resistant to atmospheric agents and mechanical influences.
Man kocht Wolle mit Kaljumbichromat und Ameisensäure oder einer anderen Hilfsbeize. Die Chromsäure muß jedoch vollkommen reduziert werden, um keine Störungen beim Verküpen hervorzurufen.Wool is boiled with Kaljumbichromate and formic acid or another auxiliary stain. However, the chromic acid must be completely reduced in order not to interfere with vetting to evoke.
