Description

Verfahren zum Färben von Pelzen, Haaren und ähnlichen Stoffen. Bekanntlich lassen sich Anilinchlorhyd!rat und ähnliche Salze unter Mitverwendung von geeigneten Oxydationsmitteln, wie Kupfersalzen, Bichromat, Alkalichloraten und Salzsäure, zum Färben von Pelzwerk und, ähnlichen Stoffen, besonders im Tauchverfahren, nicht verwenden, da die sehr stark dissozierte Mineralsäure sehr schädlich auf das Leder des Pelzes einwirkt.Process for dyeing fur, hair and similar fabrics. As is well known aniline chlorohydrate and similar salts can be used with the use of suitable Oxidizing agents, such as copper salts, bichromate, alkali chlorates and hydrochloric acid, for Do not use dyeing of fur and similar fabrics, especially in the dipping process, as the very strongly dissociated mineral acid is very harmful to the leather of the fur acts.

Drückt man aber die Dissoziation der Säure durch Zugabe von Neutralsalzen, wie Chlornatrium, Natriumsulfat usw., herab, so erhält man sehr gute Färbeergebnisse, besonders in bezug auf Erhaltung der Weichheit des Leders und der Haare. Der hervorragende technische Effekt liegt aber nicht nur im letztgenanntem Umstand, sondern vielfach auch in der erzielten, sehr guten Lichtechtheit der Färbung.But if the dissociation of the acid is suppressed by adding neutral salts, like sodium chloride, sodium sulphate etc., very good staining results are obtained, especially with regard to maintaining the softness of the leather and the hair. The excellent one The technical effect lies not only in the last-mentioned circumstance, but in many ways also in the very good lightfastness of the dyeing achieved.

Es lassen sich nach diesem Färbeverfahren die Salze der aromatischen Amino- und Iminoverbindungen verwenden, die einen stark @ sauren Charakter aufweisen, also dadurch bisher für Pelzfärberei nicht geeignet Beispiel. Man stellt sich -eine etwa ioprozentige Chl'ornatriumlösung her und verwendet diese sowohl zum Lösen des Färbesalzes, als auch zur Ergänzung der Färbeflottenmenge in folgender Weise: Die gegebenenfalls wie üblich vorgebeizten Pelzfelle kommen in folgende Flotte: 3 bis 5 g Anilinchlorhydrat im Liter gelöst als Farbflotte. Zusatz Kupfersulfatlösünk i : 1o -- 20 ccm + Bichromat i : 1o - 3occm. fleißig bewegen, nach einer Stunde Zusatz von einer Mischung aus 40 ccm Natriumchlorat i : io + 2o ccm Salzsäure (37prozentig) i : io.It can be the salts of the aromatic Use amino and imino compounds that have a strongly acidic character, so so far not suitable for fur dyeing example. One poses - one about 10% sodium chloride solution and uses this to dissolve the Dyeing salt, as well as to supplement the amount of dye liquor in the following way: The If necessary, as usual pre-stained fur skins are in the following liquor: 3 to 5 g of aniline chlorohydrate per liter dissolved as a dye liquor. Addition of copper sulfate solution i: 1o - 20 ccm + bichromate i: 1o - 3occm. Moving diligently after an hour Addition of a mixture of 40 ccm sodium chlorate io + 2o ccm hydrochloric acid (37 percent) i: io.

Bei öfterer Bewegung bleiben die Pelze in dieser Flotte etwa 3 bis 24 Stunden, je nach gewünschtem Ton. Etwa % Stunde bevor man die Pelze herausnimmt, neutralisiert man gegebenenfalls mit Boraxlösung bis zur schwach boraxalkalischen Reaktion, nimmt heraus, spült gut und behandelt wie üblich weiter. Man erhält neben einem lichtechten Grau ein tadellos weiches und zügiges Leder.With frequent movement, the pelts remain in this liquor for about 3 to 24 hours, depending on the tone you want. About% hour before taking out the furs, if necessary, it is neutralized with borax solution until it is slightly alkaline with borax Reaction, take out, rinse well and continue handling as usual. One receives besides a lightfast gray an impeccably soft and fast leather.

Mit stark sauer reagierenden Salzen anderer Basen der aromatischen Reihe oder Gemischen davon, kann das Verfahren in gleicher Weise ausgeführt werden, z. B. erhält man aus Monobenzylanilinchlorhydrat ein Blaugrau, aus Monjbenzyl-2 - 6-toluylend iaminchlorhyd'rat ein helles Gelblichgrau, aus Mono-ß-naphtyl-2 - 6-toluylendiaminchlorhvdrat ein helles Rehbraun.With strongly acidic salts of other aromatic bases Series or mixtures thereof, the process can be carried out in the same way, z. B. Monobenzylanilinechlorhydrat gives a bluish gray, Monjbenzyl-2 - 6-tolylenediamine chlorohydrate a light yellowish gray, from mono-ß-naphthyl-2 - 6-toluylenediamine chlorohydrate a light fawn brown.
