Description

Verfahren zur Erzeugung von Färbungen und Drucken mit Küpenfarbstoffen. In dem Hauptpatent 48487 ist unter anderm ein Verfahren zum Färben oder Bedrucken von Textilfasern beschrieben, welches darin besteht, daß die Faser mit einer Lösung eines durch Behandlung von Leukoküpenfarbstoffen mit Chlorsulfonsäure in Gegenwart einer tertiären Base beispielsweise erhältlichen Stoffes, die gleichzeitig noch ein Oxydationsmittel enthält, imprägniert wird. Dieses Oxydationsmittel soll in neutralem oder schwach alkalischem Medium unwirksam sein; es soll seine Wirksamkeit in saurem Medium entfalten. Die so geklotzte Faser wird getrocknet und durch ein Säurebad gezogen, wobei das Oxydationsmittel die Entwicklung der Färbung bewirkt. Als Oxydationsmittel für diese Zwecke haben sich geeignet erwiesen u. a. die Salze der Chromsäure, ferner Nitrite, namentlich Natriumnitrit.Process for producing dyeings and prints with vat dyes. In the main patent 48487, among other things, a method for dyeing or printing of textile fibers described, which consists in that the fiber with a solution one by treating leuco vat dyes with chlorosulfonic acid in the presence a tertiary base, for example, available substance that at the same time contains an oxidizing agent, is impregnated. This oxidizer is said to be in neutral or weakly alkaline medium will be ineffective; it is supposed to be effective unfold in acidic medium. The fiber padded in this way is dried and through a Acid bath drawn, whereby the oxidizing agent causes the development of the color. Oxidizing agents which have proven suitable for this purpose include: the salts chromic acid, and nitrites, especially sodium nitrite.

Wird auf so geklotzter Faser ferner ein llydrosulfitpräparat aufgedruckt, so wird an den betreffenden Stellen die Wirkung des Oxydationsmittels aufgehoben. Die Entwicklung der Färbung bei der Säurebehandlung wird verhindert, und es werden weiße Effekte erzeugt.If a lydrosulfite preparation is also printed on the fiber padded in this way, in this way the effect of the oxidizing agent is neutralized in the places concerned. The development of the color on the acid treatment will be prevented and it will creates white effects.

Es wurde nun gefunden, daß das Hydrostilfitpräparat ganz oder teilweise durch andere billigere Reduktionsmittel, wie z. B. Natritimstilfit, Natritimthiosulfat usw., oder all-, gemein durch irgendeinen chemischen Stob ersetzt werden kann, der geeignet ist, die Wirkung des angewendeten Oxydationsmittels aufzuheben.It has now been found that the Hydrostilfitpräparat wholly or partially by other cheaper reducing agents, such as. B. Natritimstilfit, Natritim thiosulfate etc., or generally, can be replaced by any chemical substance which is suitable to neutralize the effect of the oxidizing agent used.

Diese Reduktionsmittel wirken weniger energisch als Hydrosulfitpräparate. Sollen an Stelle von weißen farbige Effekte erzeugt «-erden, so können daher bei Verwendung der vorgenannten R eduktionsinittel mit Vorteil an Stelle von Küpenfarbstoffen, wie in dein Hauptpatent, hier die folgenden verwendet werden a) basische Farbstoffe, b) Beizenfarbstoffe, c) Farbstoffe, die sich mit Eiweiß fixieren lassen, (1) Entwicklungsfarbstoffe, wie z. B. Nitrosaminrotfarben bei Verwendung von Nati-itnnthiosulfat als Reservemittel, e) allgemein Farbstoffe, die sich fixieren lassen und die dein Reservemittel widerstehen.These reducing agents act less vigorously than hydrosulfite preparations. If colored effects are to be created instead of white, then at Use of the aforementioned reducing agents with advantage instead of vat dyes, as in your main patent, here the following are used a) basic dyes, b) mordant dyes, c) dyes that can be fixed with protein, (1) development dyes, such as B. Nitrosamine red colors when using sodium thiosulfate as a reserve agent, e) generally dyes that can be fixed and that withstand your reserve agent.
