Description

Verfahren zum Färben oder Bedrucken von Polyesterfasern mit Dispersionsfarbstoffen Es wurde gefunden, daß man das Aufziehvermögen von Dispersionsfarbstoffen auf Polyesterfasern wesentlich steigem kann, wenn man dem Färbegut vor oder gleichzeitig mit dem Färben oder Bedrucken Chalkone der allgemeinen Formel einverleibt. In der Formel bedeuten Ar und Ar' gleiche oder verschiedene aromatische Reste, die auch Substituenten, wie Alkyl-, Aralkyl-, Aryl- oder Cycloalkylgruppen, Oxy-, Alkoxy-, Nitro-, Cyan-, Acyl-, Carboxyl-, Ester-, Amid-, Amino- oder Acylaminogruppen und bzw. oder Halogenatome tragen können, und R und X Wasserstoff oder unsubstituierte oder substituierte Aryl- oder Alkylgruppen.Process for dyeing or printing polyester fibers with disperse dyes It has been found that the ability of disperse dyes to be absorbed by polyester fibers can be increased significantly if chalcones of the general formula are added to the dyed material before or at the same time as the dyeing or printing incorporated. In the formula Ar and Ar 'denote the same or different aromatic radicals which also have substituents such as alkyl, aralkyl, aryl or cycloalkyl groups, oxy, alkoxy, nitro, cyano, acyl, carboxyl, ester , Amide, amino or acylamino groups and / or halogen atoms, and R and X can carry hydrogen or unsubstituted or substituted aryl or alkyl groups.

Die Chalkone der obigen Formel lassen sich in bekannter Weise durch Kondensieren aromatischer Aldehyde oder Ketone mit aliphatisch-aromatischen Ketonen herstellen. Als Beispiele seien genannt das Benzalacetophenon, die Naphthylidenacetophenone und ihre Substitutionsprodukte.The chalconies of the above formula can be passed through in a known manner Condensation of aromatic aldehydes or ketones with aliphatic-aromatic ketones produce. Examples include benzalacetophenone and naphthylidene acetophenones and their substitution products.

Man kann diese Chalkone von vornherein in das Fasergut einspinnen; man kann aber auch die Fasern mit den feindispergierten Chalkonen aus wäßrigen Bädern vorbehandeln und bzw. oder den Färbebädern bzw. Druckpasten Chalkone zusetzen. Man kann etwa die gleiche Menge Chalkon wie Farbstoff verwenden; häufig kommt man aber auch mit geringeren Chalkonmengen aus.These chalconies can be spun into the fiber material from the outset; but you can also remove the fibers with the finely dispersed chalconies from aqueous baths pretreat and / or add chalcones to the dye baths or printing pastes. Man can use about the same amount of chalcone as dye; but one often comes also with smaller amounts of chalcone.

Auf diese Weise erhält man unter schonenden Bedingungen, nämlich in sehr kurzer Färbe- oder Dämpfzeit und bei verhältnismäßig niedrigen Temperaturen, sehr kräftige, klare Färbungen oder Drucke.In this way, under gentle conditions, namely in very short dyeing or steaming time and at relatively low temperatures, very strong, clear colors or prints.

Gegenüber Färbungen, die mit den üblichen Färbebeschleunigern, wie z. B. den in der USA.-Patentschrift 2 394 688 und in der Zeitschrift »Textil-Praxis«, 11. Jahrgang (1956), S. 693, genannten, ausgeführt sind, zeigen sie eine nicht vorhersehbare erhebliche Überlegenheit hinsichtlich der Brillanz, der Farbtiefe und der Klarheit der Farbtöne.Compared to dyeings made with the usual dye accelerators such. B. those in the USA. Patent 2 394 688 and in the magazine "Textil-Praxis", 11th year (1956), p. 693, are executed, they show an unforeseeable significant superiority in terms of brilliance, the Color depth and the clarity of the hues.

Die in den Beispielen genannten Teile sind Gewichtsteile. Beispiel 1 30Teile feindispergiertes 5-Nitro-1,4-diaminoanthrachinon werden zusammen mit 30 Teilen Phenyl-fl-styrylketon (= Benzalacetophenon) unter Zusatz von 20 Teilen des Natriumsalzes einer Alkylnaphthalinsulfonsäure, 20 Teilen eines Gemisches aus Polyglykoläthem und eines organischen Phosphorsäureesters und 10 Teilen des Natriumsalzes eines Dialkylclisulfonimids in 100 Teilen Wasser von 70' C dispergiert. Man setzt 650 Teile Kristallgummi und weitere 140 Teile Wasser hinzu, so daß eine druckfähige Paste entsteht. Mit dieser Paste wird ein Langfasergewebe aus Terephthalsäureglykolpolyester bedruckt und 30 Minuten bei 0,2 atü Druck im Sterndämpfer gedämpft. Nach dem Spülen und Seifen erhält man sehr farbkräftige Drucke von violetter Farbe, hoher Brillanz und guten Echtheitseigenschaften. Beispiel 2 20 Teile des feindispergierten Azofarbstoffes p-Nitranilin -+- m-Chlor-N,N-dioxäthylanüin werden mit 30 Teilen Phenyl-ß-(4-nitrostyryl)-keton sowie 30 Teilen des Natriumsalzes einer Alkylnaphthalinsulfonsäure in 80 Teilen Wasser von 45' C dispergiert und dann in 860 Teile einer wäßrigen Färbeflotte von 60' C gegeben, die 20 Teile Natriumsalz eines Dialkyldisulfoniinids enthält. In diese Flotte wurden 25 Teile eines Stapelfasergewebes aus Terephthalsäureglykolpolyester gebracht. Man erhitzt innerhalb von 15 Minuten auf Kochtemperatur und hält das Bad 45 Minuten am Sieden. Nach dem Abkühlen, Spülen und Seifen erhält man eine kräftige scharlachrote Färbung. Beispiel 3 Aus 30 Teilen des dispergierten Azofarbstoffes 2-Chlor-4-nitranilin --->- N,N-Dioxäthyl-m-toluidüi wird unter Zusatz von 30 Teilen a-Naphthylidenacetophenon und den im Beispiel 1 genannten Zusätzen eine Druckpaste bereitet, die auf ein Langfasergewebe aus Terephthalsäureglykolpolyester gedruckt wird. Nach einer 2 Minuten dauernden Erhitzung auf 190' C, Spülen und Seifen erhält man kräftige rabinrote Drucke.The parts mentioned in the examples are parts by weight. Example 1 30 parts of finely dispersed 5-nitro-1,4-diaminoanthraquinone are added together with 30 parts of phenyl-fl-styryl ketone (= benzalacetophenone) with the addition of 20 parts of the sodium salt of an alkylnaphthalenesulfonic acid, 20 parts of a mixture of polyglycol ether and an organic phosphoric acid ester and 10 parts of the sodium salt of a dialkyl disulfonimide in 100 parts of water at 70 ° C dispersed. 650 parts of crystal rubber and a further 140 parts of water are added, so that a printable paste is formed. A long fiber fabric made of terephthalic acid glycol polyester is printed with this paste and steamed for 30 minutes at 0.2 atmospheric pressure in the star damper. After rinsing and soaping, prints of very strong colors of violet color, high brilliance and good fastness properties are obtained. Example 2 20 parts of the finely dispersed azo dye p-nitroaniline - + - m-chloro-N, N-dioxäthylanüin are mixed with 30 parts of phenyl-β- (4-nitrostyryl) ketone and 30 parts of the sodium salt of an alkylnaphthalenesulfonic acid in 80 parts of water of 45% ' C dispersed and then added to 860 parts of an aqueous dye liquor at 60' C containing 20 parts of the sodium salt of a dialkyl disulfonide. 25 parts of a staple fiber fabric made of terephthalic acid glycol polyester were placed in this liquor. It is heated to boiling temperature within 15 minutes and the bath is kept boiling for 45 minutes. After cooling, rinsing and soapy, a strong scarlet color is obtained. EXAMPLE 3 From 30 parts of the dispersed azo dye 2-chloro-4-nitroaniline ---> - N, N-dioxethyl-m-toluidii, 30 parts of α-naphthylidene acetophenone and the additives mentioned in Example 1 are used to prepare a printing paste which is printed on a long fiber fabric made of terephthalic acid glycol polyester. After heating at 190 ° C. for 2 minutes, rinsing and soaping, strong rabin-red prints are obtained.
