Beispiel 3 : Eine 3' igeFärbungvonBenzolichtrot 8BL (Schultz, Farbstofftabellen, 7. Aufl. [1931], Nr. 566) auf Baumwolle wird im Flottenverhältnis 1 : 20 1/2 Stunde bei Raumtemperatur in einem Bad nachbehandelt, das im Liter 3 g der nachstehend beschriebenen Lösung einer erfindungsgemäss in Betracht kommenden polyquartemären Verbindung enthält. Die Nassechtheiten der Färbung sind dann bedeutend verbessert.
Die verwendete Lösung der polyquarternären Verbindung wird auf folgende Weise bereitet :
Eine Mischung von 11,6 g l, 2-Bis-(dimethylamino)-äthan und 12, 7 g 1, 4-Dichlorbutan wurde etwa 40 Stunden auf 90-95 C erhitzt. Das entstandene Umsetzlmgsprodukt wurde dann in 50 cm ? Wasser gelöst und die Lösung wurde unter Zusatz von 30 g Ammoniumsulfat mit Wasser auf ein Gesamtgewicht von 140 g gebracht.
Die Nassechtheiten der Färbung können ebenfalls bedeutend verbessert werden, wenn man an Stelle der oben beschriebenen Lösung eine Lösung verwendet, die unter Austausch des 1, 4-Dichlorbutans durch die äquivalente Menge 1, 4-Dibrombutan hergestellt wird.
PATENTANSPRÜCHE :
1. Verwendung von solchen polyquartemären Verbindungen, die durch Umsetzung von ditertiären Äthylendiaminen mit aliphatischen Dihalogenverbindungen erhalten worden sind, als Nachbehandlungsmittel, insbesondere für Direktfärbungen.

Example 3: A 3 'dyeing of benzene light red 8BL (Schultz, Farbstofftabellen, 7th edition [1931], no. 566) on cotton is aftertreated in a liquor ratio of 1:20 1/2 hour at room temperature in a bath containing 3 g per liter contains a solution described below of a polyquaternary compound which can be considered according to the invention. The wet fastness properties of the dye are then significantly improved.
The polyquarternary compound solution used is prepared in the following way:
A mixture of 11.6 g of 1,2-bis (dimethylamino) ethane and 12.7 g of 1,4-dichlorobutane was heated to 90-95 ° C. for about 40 hours. The resulting conversion product was then in 50 cm? Dissolved water and the solution was brought to a total weight of 140 g with the addition of 30 g of ammonium sulfate with water.
The wet fastness properties of the dyeing can also be significantly improved if, instead of the solution described above, a solution is used which is prepared by replacing the 1,4-dichlorobutane with the equivalent amount of 1,4-dibromobutane.
PATENT CLAIMS:
1. Use of such polyquaternary compounds which have been obtained by reacting ditertiary ethylenediamines with aliphatic dihalogen compounds as aftertreatment agents, especially for direct dyeing.
