Bei der Fixation von Farbstoffen mit Hilfe von Metallbeizen auf der Faser können bekanntlich verschiedene Reaktionen einzeln oder zusammen, neben-oder hintereinander verlaufen ; während es bei pflanzlichen Fasern und gewissen Beizenfarbatoffen nur die reine Lackbildung ist, kommt in anderen Fällen auch noch eine Oxydation hinzu, die sich entweder nur auf den Farbstoff erstreckt, so z.

Process for the production of real dyes and prints on animals and plants
Fibers by treatment with chromium compounds.
When dyes are fixed on the fiber with the aid of metal stains, it is known that various reactions can take place individually or together, next to one another or one behind the other; while in the case of vegetable fibers and certain stain dyes it is only the pure lacquer formation, in other cases there is also an oxidation which either only extends to the dye, e.g.
B. in the wood and extract colors, blue wood, Catochu, or the fiber concerns, as is the case with the Chromietvorgengen on the animal fiber, which can experience a split by

up to a third of the previous sentences, and not only get milled, but also livelier colors and a softer, smoother, better spin-capable and easier felting fiber if you work with a miay slope of dichromate and persalts instead of pure Biehromat A mixture of equal amounts of perborate and persulfate has proven to be particularly useful. This becomes an essential one

The goods pre-dyed with Chromotrop F 4 B, Höchst Farbwerke, are, instead of as stated in the original instructions, only 3% chromium potassium and 1 # 5% sulfuric acid, only 1% chromium potassium, 0 # 5% perborate, 0 # 5% persulfate and 1'5% sulfuric acid or even easier
