Description
Verfahren zur Entwicklung von Küpenfarbstoffen auf der Faser. In der Praxis pflegte man bisher die Leukoverbindungen von Küpenfarbstoffen entweder langsam durch Einwirkung von Luftsauerstoff oder rasch durch Einwirkung geeigneter Sauerstoff abgebender Chemikalien, wie z. B: I',ichromat, Kupferv itriolsalzsäure, verdünnte Chlorkalklösung, Eisensalze von Halogenwasserstoffsäuren usw., ztt den Farbstoffen %ti oxydieren.Process for developing vat dyes on the fiber. In the In practice, the leuco compounds of vat dyes were either kept slowly by exposure to atmospheric oxygen or rapidly by exposure to suitable oxygen releasing chemicals such as B: I ', ichromate, copper vitriolic acid, dilute Chlorinated lime solution, iron salts of hydrohalic acids, etc., add to the dyes % ti oxidize.
Es wurde nun die bemerkenswerte Beobachtung gemacht, daß eine solche Oxydation \-orteilliaft mit Nitriten in sauerer Lösung wusgeführt werden kann. Man kann auch von sauren Nitratlösungen ausgehen, denen zwecks Reduktion zu Nitrit Metalle, gewisse Metalloxyr_le oder sonstige hierzu geeignete Mittel zugesetzt worden sind. Eine solche Oxydation der Leukov erbindungen hat neben einer größeren Sparsamkeit noch den Vorteil, daß die so erzielten Färbungen bzw. Drucke klarer und reiner erscheinen. Bei Verwen-,lting der in der britischen Patentschrift r 96o57 beschriebenen Produkte hat diese neue Entwicklungsart noch den besonderen Vorzug, daß man z. B. beim Entwickeln von Indigoestern mit den üblichen Oxydationsmitteln nicht so rasch die gleiche Wirkung erzielen kann. Außerdem bleibt bei Anwendung der vorliegenden Entwicklungsmethode der sogenannte Indigotest vollständig erhalten. Das Blau ist von großer Klarheit und Frische des Tones, die evtl. vorhandenen Weißpartien einwandfrei. Das aufgefundene Zerfahren führt zur vollständigen Ausnutzung der Farbstoffe.The remarkable observation has now been made that such a Oxidation can be carried out with nitrites in an acidic solution. Man can also start from acidic nitrate solutions, which for the purpose of reduction to nitrite metals, certain metal oxyres or other suitable agents have been added. Such an oxidation of the Leukovian linkages is also more economical nor the advantage that the dyeings or prints obtained in this way appear clearer and purer. When using the products described in British patent specification r 96o57 this new type of development still has the special advantage that z. B. in developing Indigoesters do not have the same effect as quickly with the usual oxidizing agents can achieve. In addition, using the present development method remains the so-called indigo test completely received. The blue is very clear and freshness of the tone, the possibly existing white areas flawless. The found Disintegration leads to the complete utilization of the dyes.
Zur Ausübung desselben wird z. B. eine Lösung von 3 g Natriumnitrit und 6 g Schwefelsäure von 66 g Be auf i Liter verwendet, man passiert auf einer Rollenkufe, spült und wascht.To exercise the same z. B. a solution of 3 g of sodium nitrite and 6 g sulfuric acid of 66 g Be used per 1 liter, one happens on one Roller skid, rinses and washes.
