Description

Verfahren zum Färben und Drucken von organischen Faserstoffen mit sauren oder direkt ziehenden Farbstoffen Es wurde gefunden, daß man auf organischen Faserstoffen, wie Wolle, Seide, Viscosekunstseide, Baumwolle, animalis;ierteCelluloseoder Superpolyamide, kräftige Gelbfärbungen erhält, wenn man die Faserstoffe mit 3-Aminopyrendi- und -trisulfonsäuren nach den für wasserlösliche Farbstoffe :bekannten Arbeitsweisen färbt oder druckt. Der Ausdruck 3-Aininopyrens:ulfonsäuren soll die entsprechenden N-lIono- und -Dialliyl- sowie -Cycloalkyl- und -Arylaminosubstitutionsverbindungen der Di- und Trisulfonsäuren .des Pyrens umfassen (zur Pyrennomenklatur s. Annalen der Chemie, 534 S. i bis i59).Process for dyeing and printing organic fibers with acidic or direct dyes It has been found that organic Fibers such as wool, silk, viscose rayon, cotton, animalis; ated cellulose or Super polyamides, strong yellow colorations are obtained if the fibers are mixed with 3-aminopyrene and trisulfonic acids according to the working methods known for water-soluble dyes colors or prints. The expression 3-ainopyrens: sulfonic acids is intended to mean the corresponding N-iono and dialliyl as well as cycloalkyl and arylamino substitution compounds of di- and trisulfonic acids. of pyrene (for pyrene nomenclature see Annalen der Chemie, 534 pp. i to i59).

Die zur Verwendung kommenden Sulfonsäuren des Pyrens werden hergestellt, indem man 3-Aminopyren- bzw. seine NT-Mono- und -Dialkyl- sowie -Cycloalkyl- und -Arylaminosubstitutionsverbindungen erschöpfend sulfoniert.The pyrene sulfonic acids used are produced by 3-aminopyrene or its NT mono- and dialkyl and cycloalkyl and -Arylamino substitution compounds exhaustively sulfonated.

Mit diesen A:minopyrensulfonsäuren erhält man Gelbfärbungen von äußerordentlicher Klarheit. Bezüglich ihres Grünstichs und ihrer Lebhaftigkeit übertreffen sie zum Teil die bisher bekannten Farbstoffe, die in diesem Farbton färben. Die Färbungen besitzen im Gegensätz zu den Färbungen mit den entsprechenden Oxypyrensulfonsäuren eine gute Säureechtheit.With these A: minopyrenesulfonic acids, extremely extraordinary yellow colorations are obtained Clarity. In terms of their green tint and liveliness, they surpass the Part of the previously known dyes that color in this shade. The colorations in contrast to the colorations with the corresponding oxypyrenesulfonic acids good acid fastness.

Man erhält eine kräftige. leuchtend grünstichig gelheFärbung von einer Lebhaftigkeit und Fluoreszenz, wie man sie seither finit Handelsfarbstoffen nicht erzielen konnte. Der Farbstoff zeichnet sich- durch sehr gutes Egalisieren und gute Waschecht- heit aus. In Grltninischinlgen mit klaren, sauren blauen Wollfarbstoffen erhält inan Grüntöne von el)enfalls ungewöhnlicher Lebh,aftigl:eit. i oo kg Viscosege« ebe werden in i 5oo 1 Flotte mit 2 kg des obigen Farbstoffs und 30 kg -Natritrmsu.Ifat etwa '/.Stunde bei 95° gefärbt.

You get a strong one. bright greenish yellow color of one Liveliness and fluorescence how to get them since then finite commercial dyes have not been achieved could.
