In der deutschen Patentschrift Nr. 228693 ist ein Verfahren zur Hsrstellsng mehr farbiger Effekte in pflanzlichen Gespinsten und Geweben beschrieben, das dadurch gekennzeichnet ist, dass auf die gefärbten oder ungefärbten Fasern oxydieren wirkende Mangansauerstoffverbindungen niedergeschlagen werden, worauf man die so vorbehandelten Fasern mit unbehandelten zusammen verarbeitet, die so erhaltenen Waren ausfärbt und dann mit Mitteln, welche die Mangansauerstoffverbindungen zerstören, nachbehandelt.
Es wurde nun gefunden, dass sich mit Hilfe von Sauerstoffverbindnngen des Cers, wie man sie auf der Faser erhält, wenn man diese mit einem löslichen Cersalz imprägniert. oder bedruckt und dann in ein alkalisches mit einem Oxydationsmittel versetztes Bad einbringt, ähnliche aber noch vielseitigere Mehrfarbeneffekte erzeugen lassen, wobei ausserdem die Arbeitsweise gegenüber der, bei welcher Manganverbindungen benutzt werden, noch mit besonderen Vorteilen verknüpft ist
Gespinste und Gewebe, welche neben unbehandelten Fasern solche enthalten, auf denen Ceroxyde niedergeschlagen sind,
lassen sich in verschiedenster Weise zwei-und mehrfarbig ausfärben. Behandelt man die mit Direktfarbstoffen oder anderen durch Oxydationswirkung leicht zerstörbaren Farbstoffe gefärbte Faser mit Säuren oder sauren Salzen, so wird der Anteil von Farbstoff, der auf die mit Ceroxyd behandelte Faser aufgezogen war, zerstört und man erzielt mit einer Reihe von Farbstoffen weisse Musterung im farbigen Grunde. Werden solche Fasern, die vorher mit oxydationsbeständigen Farbstoffen, wie z. B. Thioindigoderivaten, Autbrachinonküpenfarbstoffen, unlöslichen Azokörpern gefärbt wurden, der Präparation mit Ceroxyden unterworfen, so erzielt man vielfarbige Effekte in einem - den unbehandelten Fasern entsprechenden - baliebig gefärbten Grunde.
Die Vorbehandlung der Fasern geschieht in der Weise, dass man sie mit einer Lösung eines Cersalzes, beispielsweise mit einer Lösung von Cerchlorid von 20 bis 300 Bd, imprägniert, trocknet, dann in ein stark alkalisches Bad einbringt, das mit einem Oxydationsmittel, z. B. Natriumhypochlorit versetzt ist, spült und trocknet. Statt die Fasern im Ganzen mit Cerchlorid zu imprägnieren, kann man auch Gespinste und Gewebe durch Aufdruck verdickter Cersalze örtlich in der Aufnahmefähigkeit für Farbstoffe verändern.
Es scheint, dass der Zusatz von Sauerstoffüberträgern, z. B. Vanadiumverbindungen, sei es in der Cerchloridlösung, sei es in den sauren Abziehbädern, die Schönheit der Farbeffekte noch verbessert.
Die Vorteile des vorliegenden Verfahren gegenüber dem älteren mit Manganbister sind darin zu erblicken, dass erstens die Ceroxyde die Faser nicht anfärben, was die Arbeiten in der Weberei sehr erleichtert, zweitens die Losiösung des Sauerstoffs in den Abziehbädern glatter erfolgt, also schwächere Abziehbäder mit besserem Effekt zur Wirkung kommen können, drittens mit den Cersalzen ein noch kaum benutztes Abfallprodukt zu nützlicher industrieller Verwendung gebracht wird.

EMI1.1
German Patent No. 228693 describes a process for producing more colored effects in vegetable webs and fabrics, which is characterized in that oxidizing manganese-oxygen compounds are deposited on the dyed or undyed fibers, whereupon the pretreated fibers are processed together with untreated fibers , colors the goods obtained in this way and then post-treats them with agents that destroy the manganese-oxygen compounds.
It has now been found that with the help of oxygen compounds of the cerium, as is obtained on the fiber when the latter is impregnated with a soluble cerium salt. or printed and then placed in an alkaline bath mixed with an oxidizing agent, producing similar but even more versatile multicolor effects, the method of operation being linked to particular advantages over that in which manganese compounds are used
Spun webs and fabrics which, in addition to untreated fibers, contain those on which cerium oxides are deposited,
can be colored in two and more colors in a wide variety of ways. If the fibers dyed with direct dyes or other dyes that can easily be destroyed by oxidation are treated with acids or acid salts, the proportion of dye that was absorbed onto the ceria-treated fiber is destroyed and a series of dyes results in white patterns in the colored Reasons. Are such fibers previously treated with oxidation-resistant dyes, such as. B. thioindigo derivatives, autbrachinon vat dyes, insoluble azo bodies were dyed, the preparation with cerium oxides, so you achieve multicolored effects in a - the untreated fibers - similarly colored base.
The pretreatment of the fibers is done in such a way that they are impregnated with a solution of a cerium salt, for example with a solution of cerium chloride from 20 to 300 Bd, dried, then introduced into a strongly alkaline bath, which is treated with an oxidizing agent, e.g. B. sodium hypochlorite is added, rinses and dries. Instead of impregnating the fibers as a whole with cerium chloride, webs and fabrics can also be locally changed in their absorption capacity for dyes by printing on thickened cerium salts.
It appears that the addition of oxygen carriers, e.g. B. Vanadium compounds, be it in the cerium chloride solution or in the acidic stripping baths, the beauty of the color effects is improved.
The advantages of the present process compared to the older one with manganese can be seen in the fact that, firstly, the cerium oxides do not dye the fibers, which makes work in the weaving mill much easier, and secondly, the dissolution of the oxygen in the stripping baths is smoother, i.e. weaker stripping baths with a better effect Third, with the cerium salts, a hardly used waste product is brought to useful industrial use.
