mit Wasser und wäscht beliebig, nachdem man zweckmässig ein sellwach-alkaliselhes Bad, wie beispielsweise Seifenlösung, gegeben hat.
Für die Behandlung von Kunstseide gilt das Beispiel mit der Abänderung, dass an Stelle der 3% igen alkoholischen Lauge eine 1'5%ige angewendet wird.
2. 5 g Baumwolle werden in Wasser getaucht, gut abgepresst und in eine Lösung von 5 < jf Phosphoroxychlorid in 150cm3 Tetrachlorkohlenstoff gebracht. Nach etwa 30 Minuten nimmt man sie heraus,

dann mit Wasser, oder allein mit Wasser und wäscht beliebig, nachdem man zweckmässig ein schwach alkalisches Bad, wie beispielsweise Seifenlösung, gegeben hat.
Die Einwirkung des Phosphoroxychlorids auf das feuchte Material kann auch in gasförmigem Zustande geschehen. Man kann auch Phosphoroxychlorid mit Hilfe eines feuchten Luftstromes auf das Gut zur Einwirkung bringen.
Für gasförmige Behandlung wird die Alkalisierung in derselben Weise ausgeführt. Das Gut wird darauf etwa, fünf Minuten in eine Atmosphäre von Phosphoroxyehlorid gehängt. In beschriebener Weise wird gewaschen und nachbehandelt.
Unter die Erfindung fallen natürlich nicht nur Ligno-und Peetozellulosen, sondern auch Hydrat-, Oxy-und andere Zellulose.
Das Verfahren kann auch bei Garnen und Geweben Verwendung finden.
Das vorliegende Verfahren, sowohl mit als auch ohne vorherige Alkalisierung, hat besonders für Kunstseide oder andere glänzende Zellulosefasern, Bändchen usw. hervorragende Bedeutung, da im Gegensatz zu den bisherigen Verfahren zur Veränderung der Farbaufnahmefähigkeit, bei denen immer der Glanz des zu behandelnden Produktes verloren ging, der Glanz der Kunstseide usw. in keiner Weise beeinträchtigt wird.
PATENT-ANSPRÜCHE :
1. Verfahren zur Veränderung der Farbaufnahmefähigkeit von zellulosehaltigem Material, dadurch gekennzeichnet, dass man nach Vorbehandlung mit Alkalien Phosphoroxyehlorid darauf einwirken lässt.

with water and washes as often as you like, after you have given a salt wax-alkaline bath, such as a soap solution.
For the treatment of rayon, the example applies with the modification that a 1'5% solution is used instead of the 3% alcoholic lye.
2. 5 g of cotton are immersed in water, squeezed well and placed in a solution of 5% phosphorus oxychloride in 150 cm3 carbon tetrachloride. After about 30 minutes you take them out,
EMI2.1
then with water, or with water alone, and washes as desired, after having expediently given a weakly alkaline bath such as a soap solution.
The action of the phosphorus oxychloride on the moist material can also take place in a gaseous state. Phosphorus oxychloride can also act on the material with the aid of a stream of moist air.
For gaseous treatment, the alkalization is carried out in the same way. The goods are then hung in an atmosphere of phosphorus oxychloride for about five minutes. Washing and aftertreatment are carried out in the manner described.
The invention naturally not only includes lignocelluloses and peeto celluloses, but also hydrate, oxy and other cellulose.
The process can also be used for yarns and fabrics.
The present process, both with and without prior alkalization, is particularly important for rayon or other shiny cellulose fibers, ribbons, etc., since, in contrast to the previous processes for changing the color receptivity, in which the gloss of the product to be treated was always lost , the luster of the rayon, etc. is not affected in any way.
PATENT CLAIMS:
1. A method for changing the color absorption capacity of cellulosic material, characterized in that phosphorus oxychloride is allowed to act on it after pretreatment with alkalis.
