Description

Gegenstand der vorliegenden Erfindung ist ein Verfahren zum Färben von Cellulosefasern und von Cellulose/Polyester-Fasermischungen mit Reaktivfarbstoffen nach dem Einbad-Ausziehverfahren. Es ist dadurch gekennzeichnet, daß man unter HT-Bedingungen mit Farbstoffen färbt, die eine Dihalogentriazinyl-, Monofluortriazinyl-, Fluorpyrimidinyl- oder Dichlorchinoxalinyl-Reaktivgruppe enthalten.The present invention relates to a process for dyeing cellulose fibers and cellulose / polyester fiber mixtures with reactive dyes by the one-bath exhaust process. It is characterized in that dyeing is carried out under HT conditions with dyes which contain a dihalogenotriazinyl, monofluorotriazinyl, fluoropyrimidinyl or dichloroquinoxalinyl reactive group.

Unter HT-Bedingungen wird dabei verstanden:HT conditions are understood to mean:

Temperatur: Kochtemperatur und höher, beispielsweise 100-130°C, insbesondere etwa 105-120°C.Temperature: cooking temperature and higher, for example 100-130 ° C, in particular about 105-120 ° C.

Das Verfahren wird bei pH-Werten von etwa 7-8, 5, speziell bei etwa 7-7,5 durchgeführt.The process is carried out at pH values of about 7-8.5, especially at about 7-7.5.

Der optimale pH-Bereich hängt dabei von der Art und Menge des Farbstoffs ab. Er ist um so höher, je weiniger reaktiv der Farbstoff ist. Die Menge an alkalischem Mittel soll vorzugsweise nicht wesentlich höher sein, als für die Farbstoff-Fixierung stöchiometrisch erforderlich ist.The optimal pH range depends on the type and amount of the dye. The less reactive the dye, the higher it is. The amount of alkaline agent should preferably not be significantly higher than is stoichiometrically required for dye fixation.

Geeignete Puffer zur Einstellung des pH-Werts sind beispielsweise Natriumbicarbonat, Dinatriumhydrogenphosphat, Borax oder übliche Puffersysteme, die in der Lage sind, den obengenannten pH-Bereich aufrechtzuerhalten.Suitable buffers for adjusting the pH are, for example, sodium bicarbonate, disodium hydrogenphosphate, borax or conventional buffer systems which are able to maintain the above-mentioned pH range.

Vorzugsweise setzt man etwa 1-3 g Natriumbicarbonat oder Dinatriumhydrogenphosphat (gegebenenfalls in Kombination mit Natriumdihydrogenphosphat) pro Liter Färbeflotte ein.Preferably about 1-3 g of sodium bicarbonate or disodium hydrogen phosphate (optionally in combination with sodium dihydrogen phosphate) are used per liter of dye liquor.

Die optimale Menge richtet sich nach der Art und Menge des eingesetzten Farbstoffs.The optimal amount depends on the type and amount of the dye used.

Das Verfahren wird bevorzugt als aall-ina-Verfahren durchgeführt. Es ist besonders vorteilhaft für Reaktivfarbstoffe mit Hydrolysen-Konstanten Kw≥ 1 . 10-3 (bei pH 10,0 und 60° gemessen; vergleiche Venkataraman: The Chemistry of Synthetic Dyes; Academic Press, New York, 1972, Band Vl, Seite 352), d. h. insbesondere für Fluorpyrimidinyl-, Monofluortriazinyl- und Dichlorchinoxalinyl-Farbstoffe.The process is preferably carried out as an all-in-one process. It is particularly advantageous for reactive dyes with hydrolysis constants K w ≥ 1. 10 -3 (measured at pH 10.0 and 60 °; see Venkataraman: The Chemistry of Synthetic Dyes; Academic Press, New York, 1972, Volume Vl, page 352), ie in particular for fluoropyrimidinyl, monofluorotriazinyl and dichloroquinoxalinyl dyes .

Farbstoffe der genannten Art sind in der Literatur in großer Zahl beschrieben. Bevorzugt gelangen dabei Azo-, Anthrachinon-'und Phthalocyan-Farbstoffe zur Anwendung.Dyes of the type mentioned are described in large numbers in the literature. Azo, anthraquinone and phthalocyanine dyes are preferably used.

Das Verfahren eigent sich vorzugsweise zum einbadigen Färben von Baumwolle- und Zellwolle-Mischmaterialien in Strang und Stück, insbesondere solchen mit Polyester, Rayon-Spinnkuchen und Zellwolle-Kreuzspulen sowie mercerisierter Baumwolle in Garn- und Stückform.The method is preferably suitable for single-bath dyeing of cotton and rayon blended materials in strand and piece, in particular those with polyester, rayon spun cake and rayon cross-wound bobbins as well as mercerized cotton in yarn and piece form.

Bei Verwendung einer Mischung aus Reaktivfarbstoffen und Dispersionsfarbstoffen lassen sich bei Cellulose-Polyester-Mischmaterialien beide Faserarten gleichzeitig färben.When using a mixture of reactive dyes and disperse dyes, both types of fibers can be dyed simultaneously in cellulose-polyester blends.

Das Verfahren wird im einzelnen folgendermaßen durchgeführt:The detailed procedure is as follows:

Eine in einem Färbeapparat (z. B. Garnfärbeapparat, Haspelkufe oder Jetfärbeapparat) befindliche Färbeflotte, welche Farbstoff, Textilmaterial (Flottenverhältnis etwa 1 :5-1 :20), Alkalispender (insbesondere Natriumbicarbonat) und weitere übliche Zusätze, beispielsweise Salze wie Natriumsulfat, sowie Reduktionsinhibitoren wie m-nitrobenzolsulfonsaures Natrium enthält, wird in etwa 15-60 Minuten auf 100-130° erhitzt und bei dieser Temperatur gehalten, bis die Färbung beendet ist.A dyeing liquor in a dyeing machine (e.g. yarn dyeing machine, reel runner or jet dyeing machine), which dye, textile material (liquor ratio about 1: 5-1: 20), alkali dispenser (especially sodium bicarbonate) and other conventional additives, for example salts such as sodium sulfate, and Contains reduction inhibitors such as sodium m-nitrobenzenesulfonate, is heated to 100-130 ° in about 15-60 minutes and held at this temperature until the coloring is complete.

Bei Zellwolle wird vorzugsweise so gearbeitet, daß Fasermaterial, Farbstoff und alle Hilfsstoffe in eine auf etwa 70° C vorgeheizte Flotte eingebracht werden und danach auf HT-Temperatur aufgeheizt wird.In the case of cellulose, preference is given to working in such a way that fiber material, dye and all auxiliaries are introduced into a liquor preheated to about 70 ° C. and then heated to HT temperature.

Anschließend wird auf 100°C erhitzt und während dieser Zeit 1,5 Teile Natriumbicarbonat innerhalb von 10 Minuten zugesetzt. Daraufhin wird die Temperatur bei statischem Druck auf 106°C gebracht und bei dieser Temperatur 45 Minuten gefärbt. Anschließend wird wie üblich gespült, kochend geseift und getrocknet.100 parts of a rayon yarn in the form of a spin cake are mixed in a HT yarn dyeing machine with a 75 ° C. warm liquor which

 contains and the flow direction is changed in the following change: 3 minutes from the inside out and 3 minutes from the outside in. The mixture is then heated to 100 ° C. and 1.5 parts of sodium bicarbonate are added over the course of 10 minutes. The temperature is then brought to 106 ° C. under static pressure and colored at this temperature for 45 minutes. It is then rinsed as usual, soaped at the boil and dried.

Anschließend wird bei guter Flottenzirkulation auf 110°C erwärmt und 60 Minuten bei dieser Temperatur gefärbt.The mixture is then warmed to 110 ° C. with good liquor circulation and dyed at this temperature for 60 minutes.

Man erhält eine tiefe egale Rotfärbung mit guten Echtheitseigenschaften.A deep, level red color with good fastness properties is obtained.

Verwendet man anstelle des Farbstoffs lll gleiche Teile des Farbstoffs IV, so erhält man eine gleichwertige Färbung.If, instead of the dye III, the same parts of the dye IV are used, an equivalent coloration is obtained.
