Description

Verfahren zur Verbesserung der Lichtechtheit von Färbungen mit löslichen Wollfarbstoffen auf animalisierten Kunstfasern Zusatz zum Patent 722 335 Gegenstand des Patents 722 335 ist ein Verfahren zur Verbesserung der Lichtechtheit von Färbungen .auf färberisch wollähnlichen Kunstfasern aus Cellulose oder Celluloseabkömmlingen mit löslichen Wollfarbstoffen, das dadurch gekennzeichnet ist, daß, man die Fasern vor, während oder nach dem Färben mit Lösungen von Polyhalogenpolyoxytriphenylmethansulfonsäuren bei gewöhnlicher oder erhöhter Temperatur behandelt oder Kunstfasern obiger Art färbt, die während -der Herstellung unter Mitverwendung der Sulfonsäuren animalisiert worden sind.A method for improving the light fastness of dyeings with soluble wool dyes on animalized synthetic fibers addition to the Patent 722,335 subject of the patent 722 335 discloses a process for improving the light fastness of dyeings .on tinctorially wool-like synthetic fibers composed of cellulose or cellulose derivatives with soluble wool dyes, which is characterized, that, before, during or after dyeing, the fibers are treated with solutions of polyhalogenopolyoxytriphenylmethanesulfonic acids at ordinary or elevated temperatures or synthetic fibers of the above type are dyed which have been animalized during production using the sulfonic acids.

Es hat sich nun gezeigt, daß, dieses Verfahren auch auf sonstige künstliche Gebilde aus Cellulose oder Celluloseabkömmlingen, wie Filme, Stäbe, Bändchen oder auf Roß, haar, die für Wollfarbstoffe aufnahmefähig gemacht sind, anwendbar ist.It has now been shown that this method can also be applied to other artificial ones Structures made of cellulose or cellulose derivatives, such as films, rods, tapes or is applicable to horse hair that has been made receptive to wool dyes.

Beispiel Eine aus Viscoselösung in üblicher Weise hergestellte Cellulosebahn, die dadurch für Wollfarbstoffe aufnahmefähig gemacht wurde, daß man der Viscoselösung ¢% (bezogen auf den Cellulosegehalt) der Umsetzungsverbindung von Trichlorhartparaffin mit Polyäthylenpolyamin zusetzte, wird mit dem Farbstoff, hergestellt gemäß Patentschrift 64.3 322 durch Küpplung von i Mol tetrazotiertem 4., 4.' - Diaminodiphenyl - i, i' - cyclohexan mit 2M01 2-Oxynaphthalin-6, ä-disulfonsäure, gefärbt und mit 3 ab 3', 5', 3", 5"-Tetrachlor-2"-dioxytriphenylmethan-2-sulfonsäure und i o(o Essigsäure nachbehandelt. Die so erhaltene Färbung ist erheblich lichtechter als eine Färbung, die nicht einer derartigen Nachbehandlung unterworfen wurde, was für viele technische Zwecke von besonderem Interesse ist.EXAMPLE A cellulose web produced in the usual way from viscose solution, which has been made receptive to wool dyes by adding ¢% (based on the cellulose content) of the reaction compound of hard trichloro paraffin with polyethylene polyamine to the viscose solution, is combined with the dye produced according to patent 64.3 322 by killing of i mol tetrazotized 4th, 4th ' - Diaminodiphenyl - i, i '- cyclohexane with 2M01 2-oxynaphthalene-6, a-disulfonic acid, colored and with 3 from 3', 5 ', 3 ", 5" -tetrachloro-2 "-dioxytriphenylmethane-2-sulfonic acid and io (o acetic acid aftertreated. The coloration obtained in this way is considerably more lightfast than a coloration that has not been subjected to such an aftertreatment, which is of particular interest for many technical purposes.
