Description

Verfahren zum Ätzen von mit Tanninersatzmitteln hergestellten Färbungen basischer Farbstoffe Der Ätzdruck basischer Farben wird meist durch Ätzen der tannierten Gewebe vor dem Färben ausgeführt, wie dies bei dem bekannten Tanninätzartikel mittels Natronlauge der Fall ist. Man kann zwar auch die fertigen Färbungen ätzen, jedoch erhält man hierbei mit den meisten basischen Farben kein genügendes Weiß.Process for etching dyeings produced with tannin substitutes basic dyes The discharge printing of basic colors is mostly done by etching the tannic ones Fabric carried out before dyeing, as in the case of the known Tanninätzartikel Caustic soda is the case. You can also etch the finished colorations, however you won't get enough white with most basic colors.

Bei Anwendung der bekannten Tanninersatzmittel, wie beispielsweise der Schwefelungsprodukte der Phenole und deren Derivate sowie die nach dem Verfahren der Patentschriften 388 186 und 389 36o hergestellten Produkte, versagt jedoch die Methode des Tanninätzartikels, da die genannten Produkte nicht genügend von der Faser entfernt werden. Das Fehlen einer solchen Ätzmöglichkeit auf diesen Tanninersatzprodukten war ein Mangel, der sich bei deren Einführung in die Färbereipraxis empfindlich geltend machte.When using the known tannin substitutes, such as the sulphurization products of phenols and their derivatives as well as the products manufactured according to the process of patents 388 186 and 389 36o, however, the method of the tannin etch article fails because the products mentioned are not sufficiently removed from the fiber. The lack of such a possibility of etching on these tannin substitute products was a deficiency that made itself felt when they were introduced into dyeing practice.

Es wurde nun die überraschende Beobachtung gemacht, daB diese Tanninersatzmittel sich vor dem Färben mit basischen Farben leicht vollständig durch Oxydationsmittel, wie namentlich durch Chlorate, entfernen lassen und dann beim Nachfärben an den geätzten, d. h. von der Beize befreiten Stellen sehr schöne Weißeffekte zu erzielen sind, welche den auf Tanninbeize hergestellten Ätzungen nicht nachstehen. Beispiel i Die in bekannter Weise mit dem Schwefelungsprodukte aus o-Chlorphenol nach Patent 390 931 (oder anderen Tanninersatzprodukten) vorgebeizte Ware wird mit einer Ätze folgender Zusammensetzung bedruckt 22o g Britishgum 320 g Wasser - 2oo g chlorsaures Natron 2o g rotes Blutlaugensalz ioo g citronensaures Ammon 220 B6 ioo g Leukotrop O (Dimethylphenylbenzyl- ammoniumchlorid) o. dgl. 40 g Glycerin 1000 g. Nach dem Aufdruck wird gedämpft, hierauf in Wasser gut gewaschen, worauf dann das Färben mit basischen Farben, in der für den Tanninätzartikel üblichen Weise, erfolgen kann.The surprising observation has now been made that these tannin substitutes can easily be completely removed by oxidizing agents, such as chlorates, before dyeing with basic colors, and that very beautiful white effects can then be achieved on the etched, i.e. freed of the stain, areas during re-dyeing which are not inferior to the etchings produced on tannin stain. EXAMPLE i The goods which have been pre-pickled in a known manner with the sulphurisation product from o-chlorophenol according to Patent 390 931 (or other tannin substitute products) are printed with an etch of the following composition 22o g of Britishgum 320 g water - 2oo g of sodium chloride 20 g red blood liquor salt 100 g of citric acid ammonium 220 B6 100 g Leukotrope O (Dimethylphenylbenzyl- ammonium chloride) or the like. 40 g of glycerin 1000 g. After the imprint is steamed, then washed well in water, whereupon the dyeing with basic colors, in the usual manner for the tannin etching article, can take place.

Beispiel 2 Die Ware wird mit dem Schwefelungsprodukte aus o-Chlorphenol nach Patent 390 931 (oder einem anderen Tanninersatzprodukt) in bekannter Weise gebeizt, hierauf mit nachstehender Ätze bedruckt: 56o g Gummiwasser x : i Zoo g chlorsaures Natron 6o g Ferricyanammonlösung 25' B6 qo g Weinsäure i : i ioo g Leukotrop O (Dimethylphenylbenzyl- ammoniumchlorid) o. dgl. 409 Glycerin I000 g. Nach dem Trocknen wird gedämpft, gespült, evtl. schwach geseift, gespült und. ausgefärbt.Example 2 The goods are stained in a known manner with the sulphurisation product from o-chlorophenol according to patent 390 931 (or another tannin substitute product), then printed with the following etch: 56o g gum water x: i Zoo g sodium chloride 60 g of ferricyanammon solution 25 ' B6 qo g tartaric acid i: i 100 g Leukotrope O (Dimethylphenylbenzyl- ammonium chloride) or the like. 409 glycerin 1000 g. After drying, it is steamed, rinsed, possibly lightly soaped, rinsed and. colored.
