Patentiert im Deutschen Reiche vom 7. Juli 1910 ab.Patented in the German Empire on July 7, 1910.
Es ist bekannt, daß beim Bleichen von Waren, die neben pflanzlicher Rohfaser mit Küpenfarbstoffen gefärbte enthalten, sehr leicht ein Ausbluten der Küpenfarbstoffe stattfindet. Die Ursache dieser Erscheinung ist die, daß das zum Abkochen verwendete Alkali, wie Natronlauge, Soda usw., im Verein mit der Faser eine Reduktionswirkung auf die Küpenfarbstoffe ausübt, diese löslich machtIt is known that when bleaching goods, in addition to vegetable crude fiber with If vat dyes contain colored vat dyes, bleeding of the vat dyes very easily takes place. The cause of this phenomenon is that the alkali used for boiling, such as caustic soda, soda, etc., in combination with the fiber has a reducing effect on the vat dyes, making them soluble
ίο und so das Ausbluten herbeiführt.ίο and so causes bleeding.
Man hat diesem Übelstand in verschiedener Weise abzuhelfen versucht, so zt B. indem man organische reduzierbare Körper, wie Nitrobenzolsulfosäure, Anthrachinonsulfosäure u. dgl, oder anorganische reduzierbare Körper, wie Chromate, Permanganat, Bromate u. dgl., der Bäuchflotte zufügt.Attempts have been made to remedy this drawback in various ways, such as by organic t reducible body, such as nitrobenzenesulfonic acid, Anthrachinonsulfosäure u. The like, or inorganic reducible body, such as chromates, permanganate, bromates u. The like., The Bäuchflotte inflicts.
Es wurde nun die Beobachtung gemacht, daß die beabsichtigte Wirkung in viel sicherer Weise erzielt wird, wenn man solche mit Küpenfarbstoffen gefärbte Fasern verwendet, auf welche oxydierend wirkende anorganische Körper, wie insbesondere Manganbister, niedergeschlagen sind. Hierdurch wird ein Ausbluten sicher vermieden, weil die Reduktionswirkung der Bäuchlaugen im Keime an der Stelle aufgehoben wird, wo sie . ihren Ursprung nimmt. Es ist bei dieser Arbeitsweise eine Veränderung des üblichen Bäuch- und Bleichprozesses zunächst gar nicht erforderlich; außerdem kann sparsamer gearbeitet werden, weil das Schutzmittel nur auf den gefärbten Fasern aufgebracht wird und seine Menge entsprechend zu bemessen ist, während bei den früher erwähnten Verfahren die Menge des Schutzmittels der gesamten Menge der Bäuchlauge entsprechend bemessen werden muß.It has now been observed that the intended effect is much more certain Is achieved by using such fibers dyed with vat dyes, on which oxidizing inorganic bodies, such as manganese in particular, are deposited are. This reliably prevents bleeding, because the reducing effect of the abdominal lye in the germ on the Place where it is lifted. takes its origin. It is with this way of working a change in the usual bulging and bleaching process is not necessary at first; In addition, you can work more economically because the protective agent is only applied to the colored fibers and its amount is to be measured accordingly, while in the case of the previously mentioned methods measure the amount of protective agent according to the total amount of the stomach liquor must become.
Nach beendetem Bauch- und Bleichprozesse wird durch Behandeln mit Säure und Bisulfit, Wasserstoffsuperoxyd, Oxalsäure o. dgl. das Schutzmittel von den gefärbten Fasern wieder entfernt.After the abdominal and bleaching processes have ended, treatment with acid and bisulfite, Hydrogen peroxide, oxalic acid or the like. The protective agent from the dyed fibers again removed.
Für dieses Verfahren können alle Küpenfarbstoffe in Anwendung gebracht werden, die ein genügendes Maß von Widerstandsfähigkeit gegen Oxydationsmittel besitzen.All vat dyes can be used for this process have a sufficient degree of resistance to oxidizing agents.
Die mit beliebigen oxydationsbeständigen Küpenfarbstoffen gefärbte Faser wird in ein Bad von Manganchlorür von 50 Be. eingebracht, darin gut genetzt, der Überschuß der Manganlösung wird durch Abquetschen, Schleudem o. dgl. entfernt, hierauf wird getrocknet und in einem alkalischen Bade, z. B. von verdünnter Natronlauge, dem ein Hypochlorit oder ein anderes Oxydationsmittel zugesetzt werden kann, fixiert, gespült und getrocknet. Die so vorbehandelten Fasern können in Bleichartikeln verarbeitet werden, ohne daßThe dyed with vat dyes any oxidation resistant fiber is in a bath of manganous of 5 0 Be. introduced, well wetted therein, the excess of the manganese solution is removed by squeezing, slinging or the like. It is then dried and soaked in an alkaline bath, e.g. B. of dilute sodium hydroxide solution, to which a hypochlorite or another oxidizing agent can be added, fixed, rinsed and dried. The fibers pretreated in this way can be processed into bleaching articles without
