Abstract

In the production of a textile material containing aminated cellulose fibres, silk, wool or polyamide, dyed with anionic textile dye, printing is followed by washing with a wash liquor containing a polyamine N-oxide (I).

Description

Die vorliegende Erfindung liegt auf dem Gebiet des Textildrucks mit anionischen Textilfarbstoffen.The present invention is in the field of textile printing with anionic textile dyes.

Aminierte cellulosische Regeneratfasern sowie durch Aminierung modifizierte Cellulosefasermaterialien können gemäß EP-A1-0 665 311 sowie EP-A1-0 546 476 hergestellt werden. Diese Fasern und Fasermaterialien lassen sich nach üblichen Methoden im Druck mit anionischen Farbstoffen auch ohne den Einsatz von Alkali oder zusätzlichen Elektrolyten färben, da sie eine hohe Affinität zum anionischen Farbstoff besitzen. Werden die besagten aminierten textilen Gewebe oder Gewirke nach allgemein üblichen Druckverfahren bedruckt und nach dem Fixieren des Farbstoffes nach den üblichen Verfahrensweisen, z.B. durch Kalt- und Warmspülen, ausgewaschen, ist ein Anschmutzen des Weißfonds oder pastell gefärbter Stellen auf dem Gewebe durch ausgewaschenen Farbstoff, der sich zwangsläufig in den ersten Waschflotten anreichert, zu beobachten. Dieser Effekt wirkt sich sehr nachteilig auf die Verwendung aminierter textiler Fasern beim Einsatz in Textildruckverfahren aus. Ein Auswaschen nach dem Bedrucken ist jedoch für die Herstellung eines tragefertigen Textils unverzichtbar.Aminated cellulosic regenerated fibers and cellulose fiber materials modified by amination can be produced in accordance with EP-A1-0 665 311 and EP-A1-0 546 476. These fibers and fiber materials can be dyed using anionic dyes using conventional methods, even without the use of alkali or additional electrolytes, since they have a high affinity for the anionic dye. If the said aminated textile fabrics or knitted fabrics are printed according to generally customary printing processes and after fixing the dye according to the usual procedures, e.g. by cold and warm rinsing, washed out, soiling of the white fund or pastel-colored areas on the fabric can be observed through washed-out dye, which inevitably accumulates in the first wash liquors. This effect has a very disadvantageous effect on the use of aminated textile fibers when used in textile printing processes. However, washing out after printing is essential for the manufacture of a ready-to-wear textile.

Aufgabe der vorliegenden Erfindung war es daher, eine Möglichkeit zu finden, die das Anbluten ungefärbter oder hell gefärbter Stellen auf dem Textilmaterial bei der Drucknachwäsche verhindert.It was therefore an object of the present invention to find a way of preventing the unstained or lightly colored areas from bleeding on the textile material during the post-washing.

Diese Aufgabe konnte überraschenderweise durch die Zugabe eines Polyamin-N-oxids zu den Waschbädern der Drucknachwäsche gelöst werden.Surprisingly, this task was solved by adding a polyamine N-oxide to the washing baths of the postpress wash.

Gegenstand der Erfindung ist ein Verfahren zur Herstellung eines mit anionischen Textilfarbstoffen bedruckten textilen Materials, enthaltend aminierte Cellulosefasern, Seide, Wolle oder Polyamidfasern, dadurch gekennzeichnet, daß im Anschluß an den Druckvorgang eine Nachwäsche durchgeführt wird, bei der die Waschflotte ein Polyamin-N-oxid enthält.The invention relates to a process for the production of a textile material printed with anionic textile dyes, containing aminated cellulose fibers, silk, wool or polyamide fibers, characterized in that after the printing process, a post-wash is carried out in which the wash liquor is a polyamine N-oxide contains.

Die Verwendung von Polyamin-N-oxiden zusammen mit Detergentien, Bleichmitteln und optischen Aufhellern gegen das Anbluten von Begleitgeweben in der Haushaltswäsche ist aus EP-A1-0 664 332, EP-A1-0 664 333 und EP-A1-0 663 438 bekannt. Das diesen Schriften zugrundeliegende technische Problem ist jedoch grundlegend von dem der vorliegenden Erfindung verschieden, da es sich in der Haushaltswäsche bereits um tragefertige Textilien handelt, bei denen Anblut- und Anschmutzeffekte in wesentlich geringerem Maß stattfinden als dies bei der Nachwäsche eines frisch bedruckten aminierten Textilmaterials der Fall ist. Die in den genannten Schriften beschriebene Verwendung der Polyamin-N-oxide bezieht sich nur auf nicht-modifizierte Baumwollgewebe.The use of polyamine-N-oxides together with detergents, bleaching agents and optical brighteners against the staining of accompanying tissues in household laundry is known from EP-A1-0 664 332, EP-A1-0 664 333 and EP-A1-0 663 438 . However, the technical problem on which these documents are based is fundamentally different from that of the present invention, since household laundry is already ready-to-wear textiles, with bleeding and soiling effects taking place to a much lesser extent than when washing a freshly printed aminated textile material Case is. The use of the polyamine N-oxides described in the cited documents relates only to unmodified cotton fabrics.

Daß durch die erfindungsgemäße Nachwäsche ein Anbluten des Weißfonds wirkungsvoll verhindert wird, ist insbesondere deshalb überraschend, weil gerade aminierte oder aminogruppenhaltige Fasermaterialien gegenüber wasserlöslichen anionischen Textilfarbstoffen eine wesentlich höhere Affinität aufweisen als beispielsweise nicht-modifizierte Baumwollgewebe und somit eine wesentlich größere Tendenz zum Anschmutzen zeigen.The fact that the white fund effectively prevents bleeding from the white fund is particularly surprising because aminated or amino group-containing fiber materials in particular have a much higher affinity for water-soluble anionic textile dyes than, for example, unmodified cotton fabrics and thus show a significantly greater tendency to soiling.

Für das erfindungsgemäße Verfahren kommen bevorzugt solche Polyamin-N-oxide in Betracht, deren Polymerkette Polyvinyl und/oder ein Polyalkylen ist und das Amin Pyridin, Pyrrol, Imidazol, Piperidin, Pyrrolidin oder Chinolin ist.For the process according to the invention, preference is given to those polyamine N-oxides whose polymer chain is polyvinyl and / or a polyalkylene and the amine is pyridine, pyrrole, imidazole, piperidine, pyrrolidine or quinoline.

Besonders bevorzugt ist Poly(4-vinylpyridin)-N-oxid.Poly (4-vinylpyridine) -N-oxide is particularly preferred.

Die erfindungsgemäß verwendeten Polyamin-N-oxide haben eine durchschnittliche Molmasse von 500 bis 1 000 000, bevorzugt 1 000 bis 50 000. Im allgemeinen liegen sie als Mischung von Amin zu N-Oxid im Verhältnis 2:3 bis 1:1 000 000, bevorzugt 1:4 bis 1:1 000 000, insbesondere bevorzugt 1:7 bis 1:1 000 000, vor.The polyamine N-oxides used according to the invention have an average molar mass of 500 to 1,000,000, preferably 1,000 to 50,000. In general, they are a mixture of amine and N-oxide in a ratio of 2: 3 to 1: 1,000,000. preferably 1: 4 to 1: 1,000,000, particularly preferably 1: 7 to 1: 1,000,000.

Polyamin-N-oxide können hergestellt werden, indem man entweder das Amin-Monomer polymerisiert und das entstandene Polymer mit einem geeigneten Oxidationsmittel zum N-Oxid oxidiert, oder indem man das Aminoxid-Monomer selbst polymerisiert. Poly(4-vinylpyridin)-N-oxid kann beispielsweise nach der in EP-A1-0 664 333 angegebenen Methode hergestellt werden.Polyamine N-oxides can be prepared either by polymerizing the amine monomer and oxidizing the resulting polymer to the N-oxide using a suitable oxidizing agent, or by polymerizing the amine oxide monomer itself. Poly (4-vinylpyridine) -N-oxide can be produced, for example, by the method specified in EP-A1-0 664 333.

Die für das erfindungsgemäße Verfahren verwendete Waschflotte enthält das Polyamin-N-oxid zweckmäßigerweise in einer Menge von 0,003 bis 3 Gew.-%, vorzugsweise 0,03 bis 2 Gew.-%, insbesondere 0,1 bis 1 Gew.-%.The wash liquor used for the process according to the invention advantageously contains the polyamine N-oxide in an amount of 0.003 to 3% by weight, preferably 0.03 to 2% by weight, in particular 0.1 to 1% by weight.

Die Nachwäsche kann diskontinuierlich oder vorzugsweise kontinuierlich in einer Kasten- oder Siebtrommelwaschmaschine durchgeführt werden. Die Wirkung der erfindungsgemäßen Waschflotte ist so hoch, daß im kontinuierlichen, industriellen Maßstab mit Geschwindigkeiten von über 20 m/min gearbeitet werden kann.The after-washing can be carried out batchwise or preferably continuously in a box or screen drum washing machine. The effect of the washing liquor according to the invention is so high that it is possible to work at speeds of over 20 m / min on a continuous industrial scale.

In manchen Fällen ist eine einzige Nachwäsche bei einer Temperatur zwischen 20 und 100°C ausreichend. Oftmals ist es aber erforderlich, dem ersten Waschgang bei 20 bis 40°C eine Heißwäsche bei einer Temperatur von 70 bis 100°C, vorzugsweise 80 bis 99°C, besonders bevorzugt 90 bis 98°C, anzuschließen.In some cases, a single wash at a temperature between 20 and 100 ° C is sufficient. However, it is often necessary to add a hot wash at a temperature of 70 to 100 ° C, preferably 80 to 99 ° C, particularly preferably 90 to 98 ° C, to the first wash cycle at 20 to 40 ° C.

In einer bevorzugten Ausführungsform wird zwischen dem ersten Waschgang bei 20 bis 40°C und der besagten Heißwäsche ein weiterer Waschgang bei einer Temperatur von 30 bis 70°C, vorzugsweise 35 bis 50°C, durchgeführt.In a preferred embodiment, between the first wash cycle at 20 to 40 ° C and said hot wash, a further wash at a temperature of 30 to 70 ° C, preferably 35 to 50 ° C, performed.

In einer besonders bevorzugten Ausführungsform werden bedruckte, aminierte Cellulosegewebe oder Seidengewebe zunächst mit einer Lösung, die 0,01 bis 2 Gew.-%, bevorzugt 0,1 bis 1 Gew.-%, einer etwa 30 gew.-%igen Polyamin-N-oxid-Lösung enthält, bei Raumtemperatur behandelt. Anschließend wird dieser Vorgang bei 35 bis 45°C mit einer Lösung, die wiederum 0,01 bis 2 Gew.-%, bevorzugt 0,1 bis 1 Gew.-%, einer 30 gew.-%igen Polyamin-N-oxid-Lösung enthält, wiederholt. Es folgt ein Waschvorgang bei 95 bis 98°C mit einer Waschflotte, die nochmals 0,01 bis 2 Gew.-%, bevorzugt 0,1 bis 1 Gew.-%, einer 30 gew.-%igen Polyamin-N-oxid-Lösung und gegebenenfalls ein handelsübliches Netzmittel enthält. Anschließend wird mit warmem und kaltem Wasser gespült und getrocknet.In a particularly preferred embodiment, printed, aminated cellulose fabric or silk fabric is first treated with a solution containing 0.01 to 2% by weight, preferably 0.1 to 1% by weight, of an approximately 30% by weight polyamine-N contains oxide solution, treated at room temperature. This process is then carried out at 35 to 45 ° C. with a solution which in turn contains 0.01 to 2% by weight, preferably 0.1 to 1% by weight, of a 30% by weight polyamine-N-oxide Solution contains, repeated. This is followed by a washing process at 95 to 98 ° C. with a washing liquor which again contains 0.01 to 2% by weight, preferably 0.1 to 1% by weight, of a 30% by weight polyamine-N-oxide Solution and optionally a commercial wetting agent contains. It is then rinsed with warm and cold water and dried.

Die für das erfindungsgemäße Verfahren in Betracht kommenden textilen Materialien sind wie beispielsweise gemäß EP-A1-0 665 311 oder EP-A1-0 546 476 aminierte Cellulose- oder aminierte Celluloseregeneratfasern, wie aminierte Baumwolle, aminierte Viskose, sowie Seidengewebe, Wolle und Polyamide.The textile materials which are suitable for the process according to the invention are, for example, according to EP-A1-0 665 311 or EP-A1-0 546 476, aminated cellulose or regenerated cellulose regenerated fibers, such as aminated cotton, aminated viscose, and also silk fabric, wool and polyamides.

Die genannten textilen Materialien können nach beliebigen Textildruckverfahren, wie beispielsweise Direktdruck, Ätzdruck, Additionsdruck oder Reservedruck mit anionischen, wasserlöslichen Textilfarbstoffen, wie Direktfarbstoffen oder vorzugsweise Reaktivfarbstoffen und unter Anwendung der hierfür bekanntermaßen eingesetzten Temperaturbereiche, Farbstoff- und Chemikalienmengen bedruckt werden. Die Textildruckverfahren können in der Technik beispielsweise als Rouleaux- oder Maschinendruck, als Film- oder Siebdruck oder als Ink-Jet-Druck ausgeführt werden. Nach dem Bedrucken wird der Farbstoff thermisch oder durch Dämpfen in üblicher Weise, wie etwa der Ein- oder Zweiphasentechnik, auf der Faser fixiert. Hieran schließt sich die erfindungsgemäße Nachwäsche an.The textile materials mentioned can be printed with anionic, water-soluble textile dyes, such as direct dyes or preferably reactive dyes and using the temperature ranges, amounts of dyes and chemicals known to be used for this purpose, using any textile printing process, such as direct printing, etching printing, addition printing or reserve printing. In the art, the textile printing processes can be carried out, for example, as Rouleaux or machine printing, as film or screen printing or as inkjet printing. After printing, the dye is fixed to the fiber thermally or by steaming in a conventional manner, such as the one- or two-phase technique. This is followed by the afterwash according to the invention.

Um mehrfarbige Drucke zu erhalten, wird ein Vielfarbdruck mit den Grundfarben für die subtraktive Farbmischung (Gelb, Cyan, Magenta und Schwarz) ausgeführt. Als Cyan-Farbstoff werden C.I. Direct Blue 199, als Gelb-Farbstoff C.I. Direct Yellow 34, als Magenta-Farbstoff C.I. Direct Red 79 und als Schwarz-Komponente C.I. Direct Black 162:1 verwendet. Der Drucker arbeitet nach dem "Drop on Demand"-Verfahren und der Tintentropfen wird thermisch (Bubble Jet-Verfahren) erzeugt. Das bedruckte Gewebe wird dann 2 Min gedämpft.A modified viscose fabric produced as in Example 4 of EP-A1-0 665 311 is carried out by means of one or two rollers for guiding and tensioning the fabric under an ink-jet printing unit and printed with an aqueous solution of direct dyes. To obtain multi-color prints, multi-color printing is carried out with the basic colors for the subtractive color mixing (yellow, cyan, magenta and black). As a cyan dye, C.I. Direct Blue 199, as a yellow dye C.I. Direct Yellow 34, as a magenta dye C.I. Direct Red 79 and as a black component C.I. Direct Black 162: 1 used. The printer works according to the "drop on demand" process and the ink drop is generated thermally (bubble jet process). The printed fabric is then steamed for 2 minutes.

Anschließend wird das Material mit einer Lösung, die 1 % einer 30 %igen Lösung von Poly-(4-vinylpyridin)-N-oxid in Wasser enthält, bei Raumtemperatur für 3 min behandelt. Dieser Vorgang wird bei 50°C mit einer Lösung, die 0,5 % der gleichen 30 %igen Lösung enthält, wiederholt. Es folgt ein Waschvorgang bei 95 bis 98°C mit einer Waschflotte, die nochmals 0,2 % des 30 %igen Poly-(4-vinylpyridin)-N-oxids und ein handelsübliches Netzmittel enthält. Anschließend wird mit Wasser warm und kalt gespült und getrocknet. Der resultierende Druck verfügt über gute Allgemeinechtheiten und zeigt kein Ausbluten des Druckes in den Weißfond.The material is then treated with a solution containing 1% of a 30% solution of poly (4-vinylpyridine) -N-oxide in water at room temperature for 3 minutes. This process is repeated at 50 ° C with a solution containing 0.5% of the same 30% solution. This is followed by a washing process at 95 to 98 ° C. using a washing liquor which again contains 0.2% of the 30% poly (4-vinylpyridine) -N-oxide and a commercially available wetting agent. It is then rinsed warm and cold with water and dried. The resulting print has good general fastness properties and shows no bleeding of the print into the white background.

A modified viscose fabric produced as in Example 4 of EP-A1-0 665 311 is printed and washed out using a single-phase printing process. For this purpose, a printing paste is first produced, which is composed as follows:
40 g
a turquoise reactive dye, known from DE-A-1 179 317, Example 2,
250 g
Water,
100 g
Urea,
500 g
medium viscous, neutral 8% sodium alginate thickening,
25 g
NaHCO 3 .

Die Paste wird anschließend mit Wasser auf 1 000 g aufgefüllt. Mit dieser Druckpaste wird das Material im Einphasendruckverfahren auf bekannte Art und Weise bedruckt. Die Paste wird im Flachfilmdruck auf das modifizierte Viskosegewebe gedruckt und anschließend bei 103°C 15 min gedämpft. Man arbeitet entsprechend den Angaben des Beispiels 1 weiter und erhält ein bedrucktes, türkisfarbenes Gewebe, auf dem keinerlei Anbluteffekte auf dem weißen Fond zu beobachten sind.The paste is then made up to 1,000 g with water. This printing paste is used to print the material in a known manner using the single-phase printing process. The paste is printed on the modified viscose fabric in flat film printing and then steamed at 103 ° C for 15 min. You continue to work according to the information in Example 1 and get one printed, turquoise-colored fabric, on which no staining effects can be observed on the white background.

Gleiche Ergebnisse werden erhalten, wenn statt modifizierter Regeneratcellulosegewebe ein Seidengewebe verwendet wird.The same results are obtained if a silk fabric is used instead of modified regenerated cellulose fabric.
