Description

Verfahren zur Verbesserung der Echtheitseigenschaften von Färbungen mit substantiven _ Farbstoffen auf Cellulesefasern gegen nicht alkalische Behandlung Es wurde gefunden, daß man die Echtheitseigenschaften von Färbungen von substantiven Farbstoffen auf Cellulosefasern gegen nicht alkalische Behandlung dadurch verbessern kann, daß man die gefärbte Faser mit Lösungen von Salzen von Basengemischen nachbehandelt, welche Polyalkylenpolyamine der allgemeinen Formel N H= (Alkylen N H) >2 alkylen N H2 enthalten. Eine Verbesserung der Echtheitseigenschaften in stark alkalischen Bädern, also bei der eigentlichen Wäsche, tritt -zwar nicht ein, in denjenigen Fällen jedoch, in denen es nur auf die Verbesserung der Wasser-, Säurekoch-, N.aßbügelechtheit ankommt, in denen also die Ware keiner stark alkalischen Behandlung unterliegt, kann man bereits auf diese sehr billige Art und Weise einen sehr guten Effekt erzielen.Process for improving the fastness properties of dyeings with substantive _ dyes on cellulose fibers against non-alkaline treatment It has been found that the fastness properties of dyeings of substantive Improve dyes on cellulose fibers against non-alkaline treatment it is possible to post-treat the dyed fiber with solutions of salts of base mixtures, which polyalkylenepolyamines of the general formula N H = (alkylene N H)> 2 alkylene Contains N H2. An improvement in the fastness properties in strongly alkaline Bathing, i.e. during the actual washing, does not occur in those cases however, in which it is only about improving the water, acid boiling and wet ironing fastness arrives, in which the goods are not subject to any strong alkaline treatment, you can already achieve a very good effect in this very cheap way.

Basen, die eine Verbesserung der Echtheitseigenschaften von Färbungen in dem obenerwähnten Sinne bewirken, sind bereits bekannt. Es handelt sich dabei jedoch durchweg um Basen, welche Alkylreste mit einer Kette von zahlreichen Kohlenstoffatomen, mindestens 7, enthalten (vgl. die britischen Patentschriften 366 918, 383 634., 390 553 und 398I75). Diesen gegenüber haben die hier verwendeten hochpolymeren mehrwertigen Amine den Vorteil, d.aß von ihnen, wahrscheinlich wegen ihres sehr niederen Äquivalentgewichtes, nur shr kleine Mengen erforderlich sind. Beispiel Man behandelt Baumwollgarn, das mit 3 % Siriusblau B R (S c h u 1 t z, Farbstofftabell'en, 7. Auflage, II. Bd., S. 197) gefärbt ist, 2o Minuten in einer-Lösung, welche pro Liter 0,4 g des im Patent 727 917 genannten hochpolymeren Polyamins und z g Ameisensäure, enthält und spült gegebenenfalls. Die Färbung blutet in niclt- alkalischen Bädern nicht merklich ab.Bases which improve the fastness properties of dyeings in the above-mentioned sense are already known. However, these are all bases which contain alkyl radicals with a chain of numerous carbon atoms, at least 7 (cf. British patents 366 918, 383 634, 39 0 553 and 398175). The high polymeric polyvalent amines used here have the advantage over these, i.e. only very small amounts of them are required, probably because of their very low equivalent weight. EXAMPLE Cotton yarn dyed with 3% Sirius blue BR (S chu 1 tz, Farbstofftabell'en, 7th edition, II. Vol., P. 197) is treated for 20 minutes in a solution containing 0.4 g of the 727 Patent high polymeric polyamine, and z g of formic acid mentioned 917 contains, and rinsed if necessary. The color does not noticeably bleed off in non-alkaline baths.

An Stelle der Ameisensäure lassen sich mit gleichem Erfolge auch ' andere organische Säuren oder auch Mineralsäuren verwenden.Instead of formic acid, ' use other organic acids or mineral acids.
