Von den Verbindungen unter den Formeln 2 bis 6 sind in den erfindungsgemäßen Gemischen die Verbindungen der folgenden Formeln bevorzugt:
Bevorzugt sind auch erfindungsgemäße Mischungen von optischen Aufhellern bestehend aus einer Verbindung der Formel 1a
Bevorzugt sind auch Mischungen von optischen Aufhellern bestehend aus einer Verbindung der Formel 1a und einer oder mehreren Verbindungen der folgenden Formeln.
Ganz besonders bevorzugt sind von den Verbindungen unter der Formel 2 die Verbindungen der Formel
Das Mischungsverhältnis für die einzelnen Komponenten liegt zwischen 0,05 und 0,95, vorzugsweise 0,20 - 0,80 Gew.-Teilen für die Verbindungen der Formel 1 und entsprechend 0,95 bis 0,05, vorzugsweise 0,80 - 0,20 Gew.-Teilen für die übrigen Verbindungen der Formeln 2 bis 6. Diese Verbindungen der Formeln 2 bis 6 können einzeln aber auch in beliebiger Mischung untereinander eingesetzt werden, wobei das Mischungsverhältnis dieser Verbindungen untereinander gänzlich unkritisch ist und beliebig variiert werden kann. Gleiches gilt für die beiden unter Formel 1 fallenden Aufheller die sowohl einzeln als auch im Gemisch unter allen denkbaren Mischungsverhältnissen eingesetzt werden können.The mixing ratio for the individual components is between 0.05 and 0.95, preferably 0.20-0.80 parts by weight for the compounds of formula 1 and correspondingly 0.95 to 0.05, preferably 0.80-0 , 20 parts by weight for the other compounds of the formulas 2 to 6. These compounds of the formulas 2 to 6 can be used individually or in any mixture with one another, the mixing ratio of these compounds with one another being completely uncritical and being able to be varied as desired. The same applies to the two brighteners covered by Formula 1, which can be used both individually and in a mixture under all conceivable mixing ratios.
Das optimale Mischungsverhältnis aller Verbindungen der Formeln 1 bis 6 hängt im Einzelfall von der Struktur der jeweiligen Verbindungen ab und läßt sich durch einfache Vorversuche unschwer ermitteln.The optimal mixing ratio of all compounds of the formulas 1 to 6 depends in individual cases on the structure of the respective compounds and can easily be determined by simple preliminary tests.
Wie bei optischen Aufhellern üblich, werden die einzelnen Komponenten durch Dispergierung in einem flüssigen Medium z.B. Wasser in die Handelsform gebracht. Man kann dabei die einzelnen Komponenten jede für sich dispergieren und dann die Dispersionen zusammen geben. Man kann aber auch die Einzelkomponenten in Substanz miteinander mischen und dann gemeinsam dispergieren. Dieser Dispergiervorgang geschieht in üblicher Weise in Kugelmühlen, Kolloidmühlen, Perlmühlen oder Dispersionsknetern. Die erfindungsgemäßen Mischungen eignen sich besonders zum Aufhellen von Textilmaterial aus linearen Polyestern, Polyamiden und Acetylcellulose. Man kann diese Mischungen aber auch mit gutem Ergebnis bei Mischgeweben verwenden, die aus linearen Polyestern und anderen synthetischen oder natürlichen Faserstoffen namentlich hydroxylgruppenhaltigen Fasern, insbesondere Baumwolle bestehen. Die Applikation dieser Mischungen geschieht dabei unter den für die Anwendung vonoptischen Aufhellern üblichen Bedingungen so beispielsweise nach dem Ausziehverfahren bei 90°C bis 130°C mit oder ohne Zusatz von Beschleunigern (Carriern) oder nach dem Thermosolverfahren. Die in Wasser unlöslichen Aufheller und die erfindungsgemäßen Mischungen können auch in organischen Lösemitteln z.B. Perchloräthylen, fluorierten Kohlenwasserstoffen gelöst zum Einsatz kommen. Dabei kann das Textilmaterial im Ausziehverfahren mit der Lösemittelflotte, welche den optischen Aufheller gelöst enthält, behandelt werden, oder man imprägniert, pflatscht, sprüht das Textilgut mit der aufhellerhaltigen Lösemittelflotte und trocknet anschließend bei Temperaturen von 120 - 220°C, wobei der optische Aufheller dabei restlos in der Faser fixiert wird. Man erhält dabei eine hervorragend aufgehellte Ware mit ausgezeichneter Lichtbeständigkeit, sowie Beständigkeit gegenüber Oxidations- und Reduktionsmitteln. Diese erfindungsgemäßen Mischungen weisen im Vergleich zu den Mischungen des japanischen Patents Sho 50(1975)-25 877 höhere Weißgrade auf und ergeben bereits bei niedrigen Temperaturen, z. B. 150°C, hervorragende Weißgrade.As is usual with optical brighteners, the individual components are brought into the commercial form by dispersion in a liquid medium, for example water. The individual components can be dispersed individually and the dispersions can then be added together. However, the individual components can also be mixed together in bulk and then dispersed together. This dispersion process takes place in the usual way in ball mills, colloid mills, bead mills or dispersion kneaders. The mixtures according to the invention are particularly suitable for lightening textile material made from linear polyesters, polyamides and acetyl cellulose. However, these mixtures can also be used with good results in mixed fabrics which consist of linear polyesters and other synthetic or natural fiber materials, in particular fibers containing hydroxyl groups, in particular cotton. These mixtures are applied under the conditions customary for the use of optical brighteners, for example by the exhaust process at 90 ° C. to 130 ° C. with or without the addition of accelerators (carriers) or by the thermosol process. The water-insoluble brighteners and the mixtures according to the invention can also be used in solution in organic solvents, for example perchlorethylene, fluorinated hydrocarbons. The textile material can be treated in the exhaust process with the solvent liquor, which contains the optical brightener, or one can impregnate, splash, spray the textile material with the brightener-containing solvent liquor and then dry at temperatures of 120 - 220 ° C, whereby the optical brightener is completely fixed in the fiber. The result is an excellently lightened product with excellent lightfastness and resistance to oxidizing and reducing agents. These mixtures according to the invention have a higher degree of whiteness than the mixtures of the Japanese patent Sho 50 (1975) -25,877 and already result in low degrees Temperatures, e.g. B. 150 ° C, excellent degrees of whiteness.
Die folgenden Tabellen-Beispiele illustrieren die Erfindung. Das angewandte Applikationsverfahren soll hier beispielgebend geschildert werden:
- Gewebeabschnitte aus Polyester-Stapelfasern werden gewaschen, getrocknet und auf einen Foulard mit wäßrigen Dispersionen imprägniert, die entweder den reinen optischen Aufheller der Formeln 1 - 6 mit einer Einsatzmenge von 0,08 Gew.-% oder ein Gemisch aus 0,064 Gew.-%, 0,04 Gew.- % und 0,016 Gew.-% des Aufhellers der Formel I mit 0,016, 0,04 bzw. 0,064 Gew.-% der Aufheller der Formel 2 - 6 enthalten.
- Fabric sections made of polyester staple fibers are washed, dried and impregnated onto a foulard with aqueous dispersions which either contain the pure optical brightener of the formulas 1-6 with an amount of 0.08% by weight or a mixture of 0.064% by weight, Contain 0.04% by weight and 0.016% by weight of the brightener of the formula I with 0.016, 0.04 and 0.064% by weight of the brightener of the formula 2-6.
Das Material wird mit einem Foulard zwischen Rollen so abgequetscht, daß sich eine Feuchtigkeitsaufnahme von ca. 80 % ergibt. Das entspricht einer Aufnahme an optischen Aufhellern auf die Ware von 0,064 p. Das so geklotzte Material wurde anschließend auf einem Spannrahmen 30 Sek. bei 170° (Tabelle I) bzw. 210° (Tabelle II) thermosoliert. Dabei wurden die jeweils angegebenen Weißgrade nach Ganz erhalten, die höher sind als Weißgrade der Mischungen aus den Aufhellertypen 2 - 6 mit 1,4-Bis-(2'-cyano-styryl)-benzol. Die Weißgrade wurden mit einem Spektralphotometer Typ DMC-25 gemessen ( Firma Carl Zeiss, Oberkochen).
