Definitions

  • the invention is in the technical field of the preparation of water-soluble reactive dyes and their use for printing and dyeing cellulosic fiber materials.
  • Reactive dyes are produced and used on an industrial scale, e.g. for the production of padding and dyeing liquors and for the production of printing pastes with which textile materials are dyed and printed.
  • the handle In addition to the wide variety of fastness properties required today, the handle also plays an important role in evaluating the high quality of the printed and dyed fiber material, since soft, flowing textile fabrics are desired by the end user.
  • Handle hardening in textile printing is still dependent on the choice of thickener.
  • Highly viscous alginate thickeners show a significant increase in hardening compared to medium and low viscosity alginate thickeners.
  • powdered meal ether and carboxymethyl cellulose by themselves or in a mixture with alginate thickeners, result in a significantly harder product handle.
  • the use of various synthetic thickeners also often leads to significant hardening of the handle.
  • the drying temperature also plays an important role in the hardening of textiles. If textile prints are dried (over-dried) at temperatures above 130 ° C, this affects the grip on the printed areas negatively due to the incrustation of the print film.
  • pressure oils based on mineral oil which also contain emulsifiers, do not have the optimally desired effect and represent a significant environmental impact.
  • the object of the present invention was therefore to develop dye settings with the aid of which the otherwise disadvantageous hardening of the handle during dyeing and especially when printing cellulosic textile materials, in particular from regenerated cellulose, can be reliably avoided and a flawlessly soft handle results.
  • the invention relates to a method for avoiding hardening of the handle when printing or dyeing cellulosic textile materials, characterized in that the printing or dyeing of the textile material is carried out with a dye preparation which consists essentially of one or more reactive dye (s) with at least two Reactive groups, 0.5 to 10% by weight, preferably 1 to 7% by weight, of a surfactant, preferably a nonionic surfactant, and 0 to 10% by weight, preferably 0.05 to 10% by weight, particularly preferably 0.1 to 6% by weight of a defoaming agent or defoaming agent mixture, based in each case on the weight of the reactive dye or dyes.
  • a dye preparation which consists essentially of one or more reactive dye (s) with at least two Reactive groups, 0.5 to 10% by weight, preferably 1 to 7% by weight, of a surfactant, preferably a nonionic surfactant, and 0 to 10% by weight, preferably 0.05 to 10% by weight, particularly preferably 0.1 to
  • the addition of the defoaming agent can be dispensed with.
  • the invention further relates to a dye preparation consisting essentially of one or more reactive dyes with at least two reactive groups, 0.5 to 10% by weight, preferably 1 to 7% by weight, of a surfactant, preferably a nonionic surfactant, and 0 , 05 to 10 wt .-%, preferably 0.1 to 6 wt .-%, of a defoaming agent or defoaming agent mixture.
  • a surfactant preferably a nonionic surfactant
  • Surfactants that produce a soft handle are, for example: fatty alcohols with 8 to 22 carbon atoms, such as cetyl alcohol, addition products of preferably 2 to 40 alkylene oxide units, in particular ethylene oxide and / or propylene oxide, to saturated or unsaturated C8-C22 monoalcohols, such as for example coconut fatty alcohols, stearyl alcohols or oleyl alcohols, on fatty acids, on fatty amides or on fatty amines each having 8 to 22 carbon atoms or on phenylphenol or on C4-C12 alkylphenols, such as nonylphenol or tributylphenol; Block polymers of 10 to 50% by weight of ethylene oxide units and 90 to 50% by weight of propylene oxide units with a molecular weight of 250 to 5000; C12-C18-alkyl-N-methylgluconamides; Sulfosuccinic acid derivatives of ethoxylated nonylphenol-formaldehyde condensation products and the
  • Preferred surfactants are, for example (EO means ethylene oxide): Coconut fatty alcohol polyglycol ether with 5 to 20 EO units, Stearyl alcohol polyglycol ether with 5 to 50 EO units, Oleyl alcohol polyglycol ether with 2 to 23 EO units, Isotridecyl alcohol polyglycol ether with 3 to 15 EO units, Coconut fatty acid polyglycol esters with 5 to 20 EO units, Stearic acid polyglycol esters with 5 to 20 EO units, Oleic acid polyglycol esters with 5 to 20 EO units, Lauryl alcohol polyglycol phosphoric acid ester, Castor oil polyglycol ester with 10 to 40 EO units, Nonylphenol polyglycol ether with 5 to 25 EO units, Block polymers which are composed of 10 to 50% by weight of ethylene oxide and 50 to 90% by weight of propylene oxide units and one Molecular weight of 250 to 5000, especially 350 to 2500 have; and C12-C16-alkyl-
  • the surfactants used according to the invention can be used individually or advantageously in a mixture of two or more. Since most of the surfactants used in accordance with the invention tend to foam, defoaming agents usually have to be added, such as, for example, those based on acetylenediol, such as, for example, 2,4,7,9-tetramethyl-5-decyne-4,7-diol in bulk or as a solution in ethylene glycol, ethylhexanol, butoxyethanol, propylene glycol, isopropanol or dipropylene glycol; further ethylhexanol, octanol, C1-C4-alkyl phosphoric acid esters, such as tri-n-butyl phosphate or tri-isobutyl phosphate; perfluorinated C6-C10 alkylphosphinic acids and perfluorinated C6-C10 alkylphosphonic acids as well as mixtures
  • the dyes used according to the invention are usually reactive dyes used for printing and dyeing cellulose-containing textile materials, but for the reasons mentioned at the outset contain two or more reactive groups and form a chemical bond with the cellulose via its reactive groups.
  • Fiber-reactive groups are, for example, those from the vinylsulfonyl and vinylsulfonamide series, the halogen-substituted s-triazinylamino and the halogen-substituted pyrimidylamino series and from the series of the optionally halogen-substituted aliphatic carbonamides, such as the chloroacetamide, the acryloylamide and the ⁇ -bromopropyl or the ⁇ , ⁇ -dibromopropionylamide residue.
  • these fiber-reactive groups can also be linked to the actual ones via an aliphatic, aromatic or araliphatic bridge member or via an alkylene residue connected to a carbonamide or sulfonamide residue Dye residue bound.
  • Such fiber-reactive groups are known in the literature, for example from DE-A-2 201 280, DE-A-2 927 102, DE-A-1 265 698, DE-A-2 614 550, EP-A- 0 040 806, EP-A-0 040 790, EP-A-070 807, EP-A-0 141 367, EP-A-0 144 766, EP-A-0 361 440, EP-A-0 374 758 and EP-A-0 377 166 and the literature mentioned in these documents.

In this way, liquid or solid powdery or granular reactive dye preparations are obtained.
  • the dyeing of cellulose-containing textiles with a reactive dye preparation according to the invention is carried out by customary methods, for example by pad dyeing processes.
  • Textiles containing cellulose are, for example, those made from regenerated cellulose or native cellulose fibers and their mixtures with synthetic fibers.
  • the present invention furthermore relates to a printing paste consisting essentially of the reactive dye preparation according to the invention and a customary alginate thickener, for example Na alginate.
  • the printing paste can be prepared by first adding the surfactants and defoaming agents to an alginate stock thickener and then mixing them with the reactive dye or dyes, or by mixing the reactive dye preparation with an alginate thickener.

Description

Die Erfindung liegt auf dem technischen Gebiet der Präparationen von wasserlöslichen Reaktivfarbstoffen und deren Verwendung zum Bedrucken und Färben von cellulosehaltigen Fasermaterialien.The invention is in the technical field of the preparation of water-soluble reactive dyes and their use for printing and dyeing cellulosic fiber materials.

Reaktivfarbstoffe werden industriell in großem Umfang produziert und angewendet, z.B. zur Herstellung von Klotz- und Färbeflotten und zur Herstellung von Druckpasten, mit denen textile Materialien gefärbt und bedruckt werden.Reactive dyes are produced and used on an industrial scale, e.g. for the production of padding and dyeing liquors and for the production of printing pastes with which textile materials are dyed and printed.

Neben den vielfältigen, heute geforderten Echtheiten spielt zusätzlich der Warengriff bei der Bewertung einer hochwertigen Qualität des bedruckten und gefärbten Fasermaterials eine wichtige Rolle, da weiche, fließende textile Flächengebilde vom Endverbraucher gewünscht sind.In addition to the wide variety of fastness properties required today, the handle also plays an important role in evaluating the high quality of the printed and dyed fiber material, since soft, flowing textile fabrics are desired by the end user.

Es ist seit langem bekannt, daß es beim Färben, insbesondere aber beim Bedrucken, zu Verhärtungen des Warengriffs kommen kann. Der Grad der Griffverhärtung hängt von verschiedenen Einflußgrößen ab:
Zum einen ist die Griffverhärtung produktspezifisch und tritt im wesentlichen bei Regeneratcellulose, weniger bei Baumwolle auf. Weiterhin wird die Griffverhärtung bei Doppelanker- und Mehrfachanker-Farbstoffen beobachtet. Gerade diese Farbstoffe gewinnen zunehmend an Bedeutung, da aufgrund ihrer hohen Fixiergrade wenig Farbstoff ins Abwasser gelangt und sie sich deshalb ökologisch günstiger verhalten. Um die Griffverhärtung auszuschließen, hat man sich bisher so beholfen, daß man insbesondere im Textildruck monoreaktive Farbstoffe eingesetzt hat unter Billigung einer höheren Belastung der Abwässer.
It has been known for a long time that hardening of the handle can occur during dyeing, but especially when printing. The degree of hardening of the handle depends on various influencing factors:
On the one hand, the hardening of the handle is product-specific and occurs mainly with regenerated cellulose, less with cotton. Furthermore, the hardening of the handle is observed with double-anchor and multiple-anchor dyes. These dyes in particular are becoming increasingly important because, due to their high degree of fixation, little dye gets into the wastewater and they therefore behave more ecologically. To rule out hardening of the handle, one has have so far managed to use monoreactive dyes, particularly in textile printing, while approving a higher pollution of the waste water.

Die Griffverhärtung ist im Textildruck weiterhin abhängig von der Wahl des Verdickungsmittels. So zeigen hochviskose Alginat-Verdicker eine deutliche Zunahme der Verhärtung im Vergleich zu mittel- und niedrigviskosen Alginat-Verdickungen.
Desgleichen bewirken Kernmehlether und Carboxymethylcellulose für sich allein oder in Mischung mit Alginatverdickungen einen deutlich härteren Warengriff. Auch der Einsatz verschiedener synthetischer Verdickungsmittel führt häufig zu deutlicher Griffverhärtung.
Handle hardening in textile printing is still dependent on the choice of thickener. Highly viscous alginate thickeners show a significant increase in hardening compared to medium and low viscosity alginate thickeners.
Similarly, powdered meal ether and carboxymethyl cellulose, by themselves or in a mixture with alginate thickeners, result in a significantly harder product handle. The use of various synthetic thickeners also often leads to significant hardening of the handle.

Weiterhin spielt bei der Verhärtung der Textilien die Trocknungstemperatur eine wichtige Rolle. Wenn Textildrucke bei Temperaturen von oberhalb 130°C getrocknet (übertrocknet) werden, beeinflußt dies den Warengriff an den bedruckten Stellen negativ infolge Verkrustung des Druckfilms.The drying temperature also plays an important role in the hardening of textiles. If textile prints are dried (over-dried) at temperatures above 130 ° C, this affects the grip on the printed areas negatively due to the incrustation of the print film.

Es hat nicht an Versuchen gefehlt, durch Hilfsmittelzusätze zu Druckpasten die Griffverhärtung zu reduzieren. Als Hilfsmittel wird z.B. Harnstoff vorgeschlagen, der bei Einsatzmengen oberhalb von 120 bis 200 g pro kg Druckpaste eine merkliche Griffverbesserung ergibt. Nachteilig sind jedoch die vom hohen Einsatz an Harnstoff resultierenden Umweltprobleme infolge der hohen Stickstoff-Belastung der Abwässer und die anwendungstechnischen Probleme infolge Reservierung der Reaktivfarbstoffe durch die Ammoniak-Bildung und durch die Entstehung von Biuret bei höheren Temperaturen (2-Phasen-Druckverfahren/neutrale Druckpaste). Durch Ammoniak- und Biuret-Bildung tritt teilweise Inaktivierung der Reaktivgruppen ein und damit eine Minderung der Fixierausbeute (unegale Drucke).There has been no lack of attempts to reduce the hardening of the handle by adding additives to printing pastes. As an aid e.g. Urea is proposed which, when used above 120 to 200 g per kg of printing paste, results in a noticeable improvement in grip. However, the environmental problems resulting from the high use of urea as a result of the high nitrogen pollution of the waste water and the application problems due to the reservation of the reactive dyes due to the ammonia formation and the formation of biuret at higher temperatures (2-phase printing process / neutral printing paste) are disadvantageous ). Ammonia and biuret formation partially inactivate the reactive groups and thus reduce the fixation yield (uneven prints).

Auch die Verwendung von Druckölen auf Mineralöl-Basis, die gleichzeitig auch Emulgatoren enthalten, bringen nicht den optimal gewünschten Effekt und stellen eine deutliche Umweltbelastung dar.The use of pressure oils based on mineral oil, which also contain emulsifiers, do not have the optimally desired effect and represent a significant environmental impact.

Aufgabe der vorliegenden Erfindung war es daher, Farbstoff-Einstellungen zu entwickeln, mit deren Hilfe die sonst übliche nachteilige Griffverhärtung beim Färben und vor allem beim Bedrucken von cellulosehaltigen textilen Materialien, insbesondere aus Regeneratcellulose, sicher vermieden werden kann und ein einwandfreier weicher Warengriff resultiert.The object of the present invention was therefore to develop dye settings with the aid of which the otherwise disadvantageous hardening of the handle during dyeing and especially when printing cellulosic textile materials, in particular from regenerated cellulose, can be reliably avoided and a flawlessly soft handle results.

Es wurde nun überraschenderweise gefunden, daß Drucke und Färbungen unter Zusatz der nachstehend beschriebenen Hilfsmittel besonders auf Regeneratcellulose zu einem weichen Warengriff führen, der sich praktisch nicht oder nicht wesentlich von unbedruckter Ware unterscheidet.It has now surprisingly been found that prints and dyeings with the addition of the auxiliaries described below lead to a soft fabric handle, particularly on regenerated cellulose, which practically does not differ or does not differ significantly from unprinted goods.

Gegenstand der Erfindung ist ein Verfahren zur Vermeidung der Griffverhärtung beim Bedrucken oder Färben von cellulosehaltigen textilen Materialien, dadurch gekennzeichnet, daß das Bedrucken oder Färben des textilen Materials mit einer Farbstoffpräparation durchgeführt wird, die im wesentlichen aus einem oder mehreren Reaktivfarbstoff(en) mit mindestens zwei Reaktivgruppen, 0,5 bis 10 Gew.-%, vorzugsweise 1 bis 7 Gew.-%, eines Tensids, vorzugsweise eines nichtionischen Tensids, und 0 bis 10 Gew.-%, vorzugsweise 0,05 bis 10 Gew.-%, besonders bevorzugt 0,1 bis 6 Gew.-%, eines Entschäumungsmittels oder Entschäumungsmittelgemisches besteht, jeweils bezogen auf das Gewicht des oder der Reaktivfarbstoffe.The invention relates to a method for avoiding hardening of the handle when printing or dyeing cellulosic textile materials, characterized in that the printing or dyeing of the textile material is carried out with a dye preparation which consists essentially of one or more reactive dye (s) with at least two Reactive groups, 0.5 to 10% by weight, preferably 1 to 7% by weight, of a surfactant, preferably a nonionic surfactant, and 0 to 10% by weight, preferably 0.05 to 10% by weight, particularly preferably 0.1 to 6% by weight of a defoaming agent or defoaming agent mixture, based in each case on the weight of the reactive dye or dyes.

Die erfindungsgemäß verwendeten Tenside können einzeln oder vorteilhaft zu zweien oder mehreren in Mischung eingesetzt werden.
Da die meisten erfindungsgemäß eingesetzten Tenside zur Schaumbildung neigen, müssen meist Entschäumungsmittel zugesetzt werden, wie beispielsweise solche auf Basis von Acetylendiol, wie beispielsweise 2,4,7,9-Tetramethyl-5-decin-4,7-diol in Substanz oder als Lösung in Ethylenglykol, Ethylhexanol, Butoxyethanol, Propylenglykol, Isopropanol oder Dipropylenglykol; weiterhin Ethylhexanol, Octanol, C₁-C₄-Alkylphosphorsäureester, wie beispielsweise Tri-n-butylphosphat oder Tri-isobutylphosphat; perfluorierte C₆-C₁₀-Alkylphosphinsäuren und perfluorierte C₆-C₁₀-Alkylphosphonsäuren sowie Mischungen der genannten Verbindungen sowie Entschäumungsmittel auf Silicon-Basis, die insbesondere in Mischung mit Emulgatoren angewandt werden.
The surfactants used according to the invention can be used individually or advantageously in a mixture of two or more.
Since most of the surfactants used in accordance with the invention tend to foam, defoaming agents usually have to be added, such as, for example, those based on acetylenediol, such as, for example, 2,4,7,9-tetramethyl-5-decyne-4,7-diol in bulk or as a solution in ethylene glycol, ethylhexanol, butoxyethanol, propylene glycol, isopropanol or dipropylene glycol; further ethylhexanol, octanol, C₁-C₄-alkyl phosphoric acid esters, such as tri-n-butyl phosphate or tri-isobutyl phosphate; perfluorinated C₆-C₁₀ alkylphosphinic acids and perfluorinated C₆-C₁₀ alkylphosphonic acids as well as mixtures of the compounds mentioned and silicone-based defoamers, which are used in particular in a mixture with emulsifiers.

Die erfindungsgemäß eingesetzten Farbstoffe sind üblicherweise zum Bedrucken und Färben von cellulosehaltigen Textilmaterialien verwendete Reaktivfarbstoffe, die aber aus den eingangs genannten Gründen zwei oder mehr Reaktivgruppen enthalten und mit der Cellulose über ihre Reaktivgruppen eine chemische Bindung eingehen.The dyes used according to the invention are usually reactive dyes used for printing and dyeing cellulose-containing textile materials, but for the reasons mentioned at the outset contain two or more reactive groups and form a chemical bond with the cellulose via its reactive groups.

Faserreaktive Gruppen sind beispielsweise solche aus der Vinylsulfonyl- und Vinylsulfonamid-Reihe, der halogensubstituierten s-Triazinylamino- und der halogensubstituierten Pyrimidylamino-Reihe und aus der Reihe der gegebenenfalls halogensubstituierten aliphatischen Carbonamide, wie der Chloracetamid-, der Acryloylamid-, der β-Brompropionylamid- oder der α,β-Dibrompropionylamid-Rest. Diese faserreaktiven Gruppen können außer über eine Aminogruppierung auch über ein aliphatisches, aromatisches oder araliphatisches Brückenglied oder über ein mit einem Carbonamid- oder Sulfonamid-Rest verbundenen Alkylenrest als Brückenglied an den eigentlichen Farbstoffrest gebunden sein. Solche faserreaktiven Gruppierungen sind zahlreich in der Literatur bekannt, wie beispielsweise aus der DE-A-2 201 280, DE-A-2 927 102, DE-A-1 265 698, DE-A-2 614 550, EP-A-0 040 806, EP-A-0 040 790, EP-A-070 807, EP-A-0 141 367, EP-A-0 144 766, EP-A-0 361 440, EP-A-0 374 758 und EP-A-0 377 166 sowie der in diesen Schriften erwähnten Literatur.Fiber-reactive groups are, for example, those from the vinylsulfonyl and vinylsulfonamide series, the halogen-substituted s-triazinylamino and the halogen-substituted pyrimidylamino series and from the series of the optionally halogen-substituted aliphatic carbonamides, such as the chloroacetamide, the acryloylamide and the β-bromopropyl or the α, β-dibromopropionylamide residue. In addition to an amino group, these fiber-reactive groups can also be linked to the actual ones via an aliphatic, aromatic or araliphatic bridge member or via an alkylene residue connected to a carbonamide or sulfonamide residue Dye residue bound. Such fiber-reactive groups are known in the literature, for example from DE-A-2 201 280, DE-A-2 927 102, DE-A-1 265 698, DE-A-2 614 550, EP-A- 0 040 806, EP-A-0 040 790, EP-A-070 807, EP-A-0 141 367, EP-A-0 144 766, EP-A-0 361 440, EP-A-0 374 758 and EP-A-0 377 166 and the literature mentioned in these documents.

Die in dem erfindungsgemäßen Verfahren eingesetzten Reaktivfarbstoffe können den unterschiedlichsten chemischen Klassen angehören, wie den Monoazo-, Disazo- oder Trisazofarbstoffen, die nach ihrer Synthese auch in Metallkomplex-Derivate, wie in ihre 1:1-Kupfer-, 1:2-Chrom- und 1:2-Kobaltkomplex-Azofarbstoffe übergeführt werden können, den Anthrachinon-Farbstoffen, den Kupferformazanfarbstoffen, den Phthalocyanin-Farbstoffen, wie beispielsweise den Kupfer- und Nickel-Phthalocyaninfarbstoffen, den Dioxazin-, den Stilben-, Cumarin- und Triphenylmethanfarbstoffen.The reactive dyes used in the process according to the invention can belong to a wide variety of chemical classes, such as the monoazo, disazo or trisazo dyes, which after their synthesis can also be used in metal complex derivatives, such as in their 1: 1 copper, 1: 2 chromium and 1: 2 cobalt complex azo dyes, the anthraquinone dyes, the copper formazan dyes, the phthalocyanine dyes such as the copper and nickel phthalocyanine dyes, the dioxazine, stilbene, coumarin and triphenylmethane dyes.

Die erfindungsgemäßen Farbstoffpräparationen können die Doppelanker- oder Mehrfachanker-Reaktivfarbstoffe einzeln oder in Mischung miteinander oder in Mischung mit monoreaktiven Farbstoffen enthalten. Die Farbstoffpräparationen enthalten den oder die Reaktivfarbstoffe in üblichen Konzentrationen, bevorzugt 5 bis 40 gew.-%ige Lösungen.The dye preparations according to the invention can contain the double anchor or multiple anchor reactive dyes individually or in a mixture with one another or in a mixture with monoreactive dyes. The dye preparations contain the reactive dye or dyes in conventional concentrations, preferably 5 to 40% by weight solutions.

Gegenstand der vorliegenden Erfindung ist auch ein Verfahren zur Herstellung der erfindungsgemäßen Reaktivfarbstoffpräparation, indem man die einzelnen vorstehend beschriebenen Komponenten homogen miteinander mischt und die erhaltene Mischung gegebenenfalls einer Sprühtrocknung oder Sprühgranulierung unterwirft. Auf diese Weise erhält man flüssige oder feste pulverförmige oder granulatförmige Reaktivfarbstoffpräparationen.The present invention also relates to a process for the preparation of the reactive dye preparation according to the invention by homogeneously mixing the individual components described above with one another and optionally subjecting the mixture obtained to spray drying or spray granulation. In this way, liquid or solid powdery or granular reactive dye preparations are obtained.

Das Färben von cellulosehaltigen Textilien mit einer erfindungsgemäßen Reaktivfarbstoffpräparation erfolgt nach üblichen Methoden, beispielsweise nach Klotzfärbeverfahren.The dyeing of cellulose-containing textiles with a reactive dye preparation according to the invention is carried out by customary methods, for example by pad dyeing processes.

Cellulosehaltige Textilien sind beispielsweise solche aus Regeneratcellulose oder nativen Cellulosefasern und deren Mischungen mit synthetischen Fasern.Textiles containing cellulose are, for example, those made from regenerated cellulose or native cellulose fibers and their mixtures with synthetic fibers.

Gegenstand der vorliegenden Erfindung ist weiterhin eine Druckpaste, bestehend im wesentlichen aus der erfindungsgemäßen Reaktivfarbstoffpräparation und einer üblichen Alginatverdickung, beispielsweise Na-Alginat.The present invention furthermore relates to a printing paste consisting essentially of the reactive dye preparation according to the invention and a customary alginate thickener, for example Na alginate.

Die Druckpaste kann hergestellt werden, indem man die Tenside und Entschäumungsmittel zunächst einer Alginat-Stammverdickung zusetzt und anschließend mit dem oder den Reaktivfarbstoffen mischt, oder indem man die Reaktivfarbstoffpräparation mit einer Alginatverdickung mischt.The printing paste can be prepared by first adding the surfactants and defoaming agents to an alginate stock thickener and then mixing them with the reactive dye or dyes, or by mixing the reactive dye preparation with an alginate thickener.

Das Bedrucken von cellulosehaltigen Textilien mit einer erfindungsgemäßen Druckpaste erfolgt nach der Methode des Einphasendrucks oder des Zweiphasendrucks. Das einphasige Bedrucken von cellulosehaltigen Textilmaterialien im Direktdruck mit Reaktivfarbstoffen ist seit längerer Zeit bekannt. Im Gegensatz zu zweiphasigen Druckverfahren, bei denen die Druckfarbe ohne das alkalische Fixierhilfsmittel zugesetzt und dieses erst in einem separaten Arbeitsgang, also in einer zweiten Phase, auf die bedruckte und getrocknete Ware aufgebracht wird, enthalten die Druckpasten im Falle einphasiger Applikation unmittelbar das zur Fixierung der Reaktivfarbstoffe auf den bedruckten Cellulosefasern notwendige Alkali, herkömmlicherweise in Form von Natriumbicarbonat oder Soda. Nach dem Druckvorgang und Trocknen werden solche einphasigen Druckerzeugnisse durch Behandlung mit Sattdampf bei 100° bis 106°C fixiert.The printing of cellulose-containing textiles with a printing paste according to the invention is carried out by the method of single-phase printing or two-phase printing. The single-phase printing of cellulose-containing textile materials in direct printing with reactive dyes has been known for a long time. In contrast to two-phase printing processes, in which the printing ink is added without the alkaline fixing aid and this is only applied to the printed and dried goods in a separate working step, i.e. in a second phase, the printing pastes in the case of single-phase application contain that for fixing the Reactive dyes on the printed cellulose fibers necessary alkali, usually in the form of sodium bicarbonate or soda. After the printing process and drying, such single-phase printed products are fixed by treatment with saturated steam at 100 ° to 106 ° C.

EO bedeutet Ethylenoxid.In the examples below, parts are parts by weight unless otherwise noted. Parts by weight are in relation to parts by volume like kilograms to liters. EO means ethylene oxide.

Beispiel 32Example 32

190 Teile einer Farbstofflösung, die 13,4 % des Farbstoffes C.I. Reactive Black 5 und ca. 6,1 % Farbstoff C.I. Reactive Orange 72 enthält, werden unter Rühren bei ca. 25 °C nacheinander mit 2 Teilen eines Ethylenoxid-Propylenoxid-Polymerisationsproduktes, das 60 % Polypropylenoxid (Molmasse 1750) und 40 % EO im Molekül enthält,
2 Teilen ethoxyliertem Pflanzenöl + 40 EO,
1 Teil Kokosfettsäurepolyglykolester + 8 EO,
1 Teil Kokosfettalkoholpolyglykolether + 8 EO,
1 Teil Stearinsäurepolyglykolester + 10 EO,
1 Teil Laurylalkoholpolyglykolphosphorsäureester und
2 Teilen Entschäumer, bestehend aus einer Lösung eines wassermischbaren Entschäumers auf Basis von perfluorierten Alkyl-Phosphin-/-Phosphonsäuren, versetzt. Es wird 2 bis 3 Stunden nachgerührt, bis eine homogene Lösung entstanden ist.
Die so hergestellte Farbstoffpräparation ergibt auf Cellulose bei Verwendung der handelsüblichen Stammverdickungen auf Alginatbasis im Ein- und Zweiphasen-Reaktivdruck tiefe schwarze Textildrucke ohne Griffverhärtung. Vergleichsdrucke mit der gleichen Farbstofflösung ohne Tensidzusätze ergeben ein deutlich schlechteres Griffverhalten.
190 parts of a dye solution which contains 13.4% of the dye CI Reactive Black 5 and about 6.1% of the dye CI Reactive Orange 72 are stirred in succession at about 25 ° C. with 2 parts of an ethylene oxide-propylene oxide polymerization product, which contains 60% polypropylene oxide (molecular weight 1750) and 40% EO in the molecule,
2 parts of ethoxylated vegetable oil + 40 EO,
1 part coconut fatty acid polyglycol ester + 8 EO,
1 part coconut fatty alcohol polyglycol ether + 8 EO,
1 part stearic acid polyglycol ester + 10 EO,
1 part lauryl alcohol polyglycol phosphoric acid ester and
2 parts defoamer, consisting of a solution of a water-miscible Defoamer based on perfluorinated alkyl phosphine - / - phosphonic acids. The mixture is stirred for 2 to 3 hours until a homogeneous solution has formed.
The dye preparation thus produced on cellulose results in deep black textile prints without hardening of the handle when using the commercially available stock thickenings based on alginate in one and two phase reactive printing. Comparative prints with the same dye solution without surfactant additives result in a significantly poorer grip.

Anstelle des im Beispiel verwendeten Entschäumers können auch Ethylhexanol, Octanol, Triisobutylphosphat, Tributylphosphat, 2,4,7,9-Tetramethyl-5-decin-4,7-diol in Substanz oder als Lösung in Glykol, Ethylhexanol, Butoxyethanol, Propylenglykol, Isopropanol oder Dipropylenglykol oder auch Mischungen der angeführten Entschäumer eingesetzt werden.Instead of the defoamer used in the example, ethylhexanol, octanol, triisobutyl phosphate, tributyl phosphate, 2,4,7,9-tetramethyl-5-decyne-4,7-diol in bulk or as a solution in glycol, ethylhexanol, butoxyethanol, propylene glycol, isopropanol or dipropylene glycol or mixtures of the defoamers mentioned.
