Tag der Anmeldung: 14. August 1954 Bekanntgemacht am 16. Februar 1956Registration date: August 14, 1954. Advertised on February 16, 1956
Es ist bekannt, daß sich Oxyanthrachinone nur in einem umständlichen Färbeverfahren in Form ihrer Metallkomplexe auf Baumwolle fixieren lassen. Ohne eine vorhergehende Beize zeigen sie nur eine sehr geringe Affinität zur Faser, und die Anfärbungen sind sehr alkaliempfindlich.It is known that oxyanthraquinones can only be shaped in a laborious dyeing process fix their metal complexes on cotton. Without a previous stain, they show only a very low affinity for the fiber, and the dyeings are very sensitive to alkali.
Es wurde nun gefunden, daß man die Oxyanthrachinone zum Färben von auf der Basis von Polyestern hergestellten synthetischen Fasern verwenden kann, ohne daß die obenerwähnten Nachteile auftreten.It has now been found that the oxyanthraquinones for dyeing on the basis of Synthetic fibers made from polyesters can be used without the disadvantages mentioned above appear.
Die Farbtöne, die dabei erhalten werden, sind weitgehend von der Zahl und der Stellung der Hydroxylgruppen in den Oxyanthrachinonen abhängig. So erhält man z. B. bei Verwendung von ι-Oxy-, ι, 2-, ι, 5- und 1, 8 - Dioxyanthrachinon gelbe, mit 1,4-Dioxy-, 1,2,4-Trioxy- und i, 4, 5-Trioxyanthrachinon orange Ausfärbungen. Die höher hydroxylierten Oxyanthrachinone ergeben orange, braune oder rote Färbungen.The hues that are obtained are largely dependent on the number and position of the Hydroxyl groups in the oxyanthraquinones dependent. So you get z. B. when using ι-Oxy-, ι, 2-, ι, 5- and 1, 8 - dioxyanthraquinone yellow, with 1,4-dioxy, 1,2,4-trioxy and i, 4, 5-trioxyanthraquinone orange colorations. The higher hydroxylated oxyanthraquinones result orange, brown or red colors.
Vor der Verwendung bringt man die Oxyanthrachinone vorteilhafterweise in einen Zustand feiner Verteilung. Das kann nach einer der gebräuchlichen Methoden geschehen, z. B. durch Umlösen aus Schwefelsäure und Vermählen oder Verkneten mit Dispergiermitteln.Before use, the oxyanthraquinones are advantageously brought into a finer state Distribution. This can be done by one of the common methods, e.g. B. by releasing Sulfuric acid and grinding or kneading with dispersants.

Die Ausführungsmethoden für die Färbungen entsprechen denen, die üblicherweise für die Anfärbungen der Polyesterfasern angewendet werden. So kann man die Oxyanthrachinone z.B. in Wasser suspendieren und die Anfärbung in der warmen oder kochenden Flotte vornehmen oder bei erhöhten Temperaturen unter Druck arbeiten. Erforderlichenfalls kann man die üblichen »Carrier«, wie z. B. Benzoesäure, zusetzen.The execution methods for the dyeing correspond to those which are usually used for the dyeing of polyester fibers. For example, the oxyanthraquinones can be suspended in water and staining can be carried out in the warm or boiling liquor or work under pressure at elevated temperatures. If necessary, you can use the usual »carriers«, such as B. benzoic acid, add.
Die Färbungen zeigen eine sehr gute Licht- und ausgezeichnete Waschechtheit.The colorations show a very good light and excellent washfastness.
i. kg Polyesterfaser wird in einer Flotte von 40 1 Wasser mit einer Suspension von 10 g 1, 4-DiQxyanthrachinon gefärbt. Man geht hierbei zweckmäßig bei 500 ein, treibt langsam zum Kochen und färbt 1V2 Stunden bei Kochtemperatür. Man erhält eine klare orange Färbung .von sehr guten Echtheiten. .i. kg of polyester fiber is dyed in a liquor of 40 l of water with a suspension of 10 g of 1,4-diQxyanthraquinone. It is expedient here at 50 0, drives slowly to the boil and dyeing 1V2 hours at boiling temperature door. A clear orange coloration with very good fastness properties is obtained. .
In entsprechender Weise kann man andere Oxyanthrachinone verwenden, , wie z.B. i-Oxy-, i, 2-DiO'Xy-, i, 5-Dioxy-, i,:8'Dioxy-, 1, 2, 4-Trioxy- und 1,4, 5-Trioxyanthrachinon. Erforderlichenfalls kann man der Flotte »Carrier« zusetzen, z. B. 100 bis 400 g Benzoesäure.In a corresponding manner one can use other Oxyanthrachinone, such as i-oxy, i, 2-DiO'Xy-, i, 5-dioxy, i: 8'Dioxy-, 1, 2, 4-Trioxy- and 1,4,5-trioxyanthraquinone. If necessary, you can add "carriers" to the fleet, e.g. B. 100 to 400 g of benzoic acid.
