Description
Verfahren zur Verbesserung der Echtheitseigenschaften. von Färbungen mit substantiven Farbstoffen auf Cellulosefasern Gegenstand des Patentes 7279z7 (z268) ist ein Verfahren zur Verbesserung der Echtheitseigenschaften von Färbungen mit substantiven Farbstoffen auf Cellulosefasern, das dadurch gekennzeichnet ist, daß man die gefärbte Faser mit Lösungen von Salzen quaternärer Ammoniumbasen nachbehandelt, die durch energische Peralkyllierung von Basengemischen hergestellt sind, welche im wesentlichen Polyalkylenpolyamine der allgemeinen Formel enthalten. Gemäß vorliegender Erfindung ist festgestellt worden, daß für dieses Verfahren Lösungen von hochmolekularen quaternären Ammoniumverbindungen, die durch Umsetzung von a-Dichlorhydrin oder Formal-a-dichlorhydrin mit Ammoniak oder Aminen und, sofern die Produkte noch nicht quaternär sind, anschließende Peralkylierung erhältlich sind, ebenfalls geeignet sind.Process for improving the fastness properties. of dyeings with substantive dyes on cellulose fibers The subject of patent 7279z7 (z268) is a process for improving the fastness properties of dyeings with substantive dyes on cellulose fibers, which is characterized in that the dyed fiber is post-treated with solutions of salts of quaternary ammonium bases, which are obtained by energetic Peralkylation of base mixtures are prepared, which are essentially polyalkylenepolyamines of the general formula contain. According to the present invention, it has been found that, for this process, solutions of high molecular weight quaternary ammonium compounds which are obtainable by reacting α-dichlorohydrin or formal α-dichlorohydrin with ammonia or amines and, if the products are not yet quaternary, subsequent peralkylation, are likewise obtainable are suitable.
Beispiel i 54 Gewichtsteile des Formars des a-Dichlorhydrins (Beilstein, q.. Aufl., Bd. i, S. 575) werden mit 95 Gewichtsteilen Tetramethy Iäthylendiamin mehrere Stunden auf r-.o bis z5o' erhitzt. Ilan befreit die entstandene Ammoniumbase durch Auswaschen mit Benzol von nicht umgesetzten Ausgangsprodukten und erhält ein in `'4 asser leicht lösliches bräunliches Harz. Durch Nachbehandeln substantivier Färbungen mit einer wäßrigen Lösung dieser Verbindung kann man die Waschechtheit substantivier Färbungen weitgehend verbessern. Beispiel 2 Zu reg Gewichtsteilen a-Dichlorhydrin und 12o Gewichtsteilen Wasser läßt man unter Rühren langsam bei 6o bis 7o° so lange Ammoniak zütropfen, bis das Dichlorhydrin in Lösung gegangen ist. Nach dem Erkalten filtriert man von einer geringen Menge einer unlöslichen Substanz ab und entfernt Ammoniak durch Erwärmen mit Natronlauge im Vakuum bei .1o bis -.5°. Durch Behandeln der so erhaltenen wäßrigen Lösung des entstehenden Basengemisches mit Dimethylsulfat in Gegenwart von Natriumcarbonat wird dieses in die quaternäre Ammoniumverbindung übergeführt.Example i 54 parts by weight of the formar of a-dichlorohydrin (Beilstein, q .. ed., vol. i, p. 575) with 95 parts by weight of tetramethy Ethylenediamine heated to r-.o to z5o 'for several hours. Ilan frees the resulting ammonium base by washing with benzene from unreacted starting materials and receives a Easily soluble, brownish resin in `` 4 water. Substituting through post-treatment Dyeings with an aqueous solution of this compound can reduce the wash fastness largely improve substantive colorations. Example 2 To reg parts by weight α-Dichlorohydrin and 120 parts by weight of water are slowly added with stirring 6o to 7o ° keep adding ammonia until the dichlorohydrin has dissolved is. After cooling, a small amount of an insoluble one is filtered off Substance off and ammonia removed by heating with sodium hydroxide solution in a vacuum at .1o up to -.5 °. By treating the resulting aqueous solution of the resulting base mixture with dimethyl sulfate in the presence of sodium carbonate, this is converted into the quaternary Ammonium compound transferred.
Die Verbindung bewirkt beim Nachbehandeln substantiv er Färbungen eine erhebliche Verbesserung der Waschechtheit.The compound causes substantive coloration during aftertreatment a significant improvement in wash fastness.
