Description
Gegenstand des Hauptpatentes Nr. 543 634 ist ein Verfahren zum Färben von sauer anfärbbare synthetische Fasern enthaltenden Textilien in Wasser enthaltenden Flotten bei pH-Werten von 5 bis X und in Gegenwart von Phenylsulfonen, die mindestens eine an einen Phenylrest gebundene Sulfonsäuregruppe enthalten und die aus a) mindestens einer Verbindung mit 6 bis 20 C-Atomen, die wenigstens eine aromatisch gebundene Hydroxylgruppe enthält (Verbindung a). und b) mindestens einer 6 bis '() C-Atome enthaltenden, aromatischen, nichtphenolischen Verbindung (Verbindung b) unter Verwendung von Schwefelsäure gewonnen wurden welches dadurch gekennzeichnet ist, dass das Sulfon zu 1 bis 30¯r aus der Komponente (a) und zu 99 bis 70% aus der Komponente (b)
hergestellt wurde.
Gegenstand des vorliegenden Zusatzpatentes ist ein Verfahren, bei welchem zusätzlich zu den oben genannten Phenylsulfonen Aryloxypolyglykoläther und äthoxylierte höhere Fettamine im Färbeverfahren verwendet werden.
Aus der DT-OS 1 444 291 sowie der DT-AS 1 132 090 ist es schon bekannt, anionaktive Hilfsmittel mit Konden sationspndukten von Äthylenoxid an Fettamine zusammen in Verfahren zum Färben von Polyamidtextilien mit sauren Wollfarbstoffen zur Verhinderung der Farbstreifigkeit zu verwenden. Namentlich genannt sind als anionaktive Hilfsmittel jedoch nur hydroxylgruppenfreic Dinaphthylmethandisulfonate (vor allem deren Na-Salze).
Aus der CH-PS 465 554 ist es ferner bekannt, in Verfahren zum Färben von Textilmaterialien aus synthetischen Polyamiden mit wasserlöslichen 1: 2-Chrom- und Kobaltkomplexfarbstoffen Mischungen aus Umsetzungsprodukten eines höher molekularen Fettamins mit Äthylenoxid und nichtionogenen Dispergatoren aus der Reihe der Polyglykoläther zu verwenden, wobei ausser diesen Stoffklassen praktisch keine als Elektrolyte wirksame Verbindungen anwesend sein sollen. Allen diesen Verfahren mangelt es jedoch an der praktischen Verwendbarkeit vor allem hinsichtlich der Aufziehgeschwindigkeit und der Egalitätseigenschaften der so gefärbten Textilien.
Das erfindungsgemäss zur Anwendung gelangende Ge- misch der Aryloxypolyglykoläther und äthoxylierten höheren Fettamine mit den Phenylsulfonen des Hauptpatentes Nr. 543 634 dient vor allem dazu, die Aufziehgeschwindigkeit und die Farbverteilung von anionischen Farbstoffen auf dem zu färbenden Material zu verbessern. Es wirkt stärker retardierend und fördert die Migration. Trotz der Retardierwirkung ziehen die Farbstoffe praktisch vollständig aufss so dass sich die Mischungen durch eine grosse Ausgiebigkeit auszeichnen. Schon bei 0,5-1%, bezogen auf das Warengewicht, wird eine ausgezeichnete egalisierende Wirkung erziehlt.
Mit der erfindungsgemässen Kombination der Phenylsulfone des Hauptpatentes mit den Aryloxypolyglykoläthern und äthoxylierten höheren Fettaminen werden Färbungen erhalten. die in ihren Eigenschaften denen bei Verwendung der oben genannten Mischungen des Standes der Technik überlegen sind.
Die erfindungsgemäss mitzuverwendenden Aryloxypolyglykoläther sind vor allem solche von höher Alkylphenolen, wie z. B. solche der Formel
EMI1.1
in welcher R für einen C6-C12 Alkylrest, vor allem einen C8 oder C9 Alkyl- oder Isoalkylrcst steht und Rl Wasserstoff ist oder dieselbe Bedeutung wie R hat, bzw. Gemische derselben und x für eine Zahl von 2()-6() steht.
Als äthoxylierte höher Alkyl-Fettamine kommen solche der Formel Rt-NH-(CH2-CH2-O)yH (II) in welcher der Rest R' für einen Alkylrest von Clo-CIZ steht und y für eine Zahl von 3()-4() steht. in Frage.
In der Mischung beträgt der Anteil an Phenylsulfonen etwa 30-S()eJ,, der Anteil an höher Alkylphenolpolyglykol äther etwa 2()-30C'r und der Anteil an höher Alkylfettamin Polyglykoläther etwa 30-4(1%, wobei die Gesamtmenge 100 sein muss.
Unter anionisehen Farbstoffen sind solche zu verstehen, die in wässriger Lösung farbige Anionen zu bilden vermögen, beispielsweise saure Egalisierfarbstoffe, Walkfarbstoffe, 1:1 und 1: 2 Metallkomplexfarbstoffe, Chromierungsfarbstoffe, Direkt- und Reaktivfarbstoffe.
Unter den sauer anfärhbaren Fasern, Fäden oder Textilien sollen Carbonamidgruppen enthaltende Polykondensations produkte oder basisch modifizierte synthetische Materialien verstanden werden. Zu den ersteren gehören vor allem die Polyamide, wie z. B. Polycaprolactam, oder Kondensationsprodukte aus Diearbonsäuren und zweiwertigen Aminen, wie z. B. Kondensationsprodukte aus Adipinsäure und Hexamethylendiamin. Basisch modifiziertc synthetische Materialien sind beispielsweise Carbonamidgruppen enthaltende Polyesterkondensate.
Im aligemeinen verwendet man das Gemisch in Mengen von ().2-S Gew.,.. bevorzugt (1,5-3 Gew. cr;bezogen auf das zu färbende Fasermaterial. Zusätzlich können im Färhebad noch weitere Hilfsmittel wie Natriumsulfat, Natriumphos phatc, Hexamethylentetramin oder Antischaummittel enthalten sein.
Die folgenden Beispiele sollen die Erfindung erläutern.
Die Teile bedeuten Gewichtsteile, die Prozente Gewichtsprozente, die Temperaturen Celsiusgrade.
Beispiel 1
100 Teile Polyamid 66 (gewirkt) werden in 3000 Teile einer 50 C warmen Färbeflotte folgender Zusammensetzung gebracht: 0,5 Teile Nylosanorange N-RL 0,1 Teil Nylosanrubin N-5BL 0,15 Teile Nylosanbalu N-SGL 200t.
4 Teile (NH4)2SO4 1 Teil einer Mischung von:
26 Teilen einer Verbindung der Formel II mit ca. 35 (CH2-CH2-O) Einheiten
35 Teilen einer Verbindung der Formel I mit ca. 40 (CH2-CH2-O) Einheiten JO Teilen Sandogen CN (eine Verbindung des Haupt patents)
Man erwärmt die Färbetiotte unter Rühren 30 Minuten lang auf Kochtemper-itur. wobei der Farbstoff langsam und gleichmässig auf das Polyamidmaterial aufzieht, und kocht weiter während 45 Minuten. Danach ist das Farbbad praktisch vollständig erschöpft und die Färbung ist gleichmässig.
Eine gleiche Färbung ohne den Zusatz von der oben genannten Verbindung der Formeln I und 11 in der genannten Mischung wird unter diesen Bedingungen fleckig.
Beispiel 2
Man bereitet ein blindes Färbebad, welches 3000 Teile Wasser, 4 Teile Ammonsulfat und 2 Teile der in Beispiel I genannten Mischung enthält. Diesem Bad fügt man 33 Teile eines mit 0,5% Nylosanorange N-RL, 33 Teile eines mit 0,1% Nylosanrubin N-SBL und 33 Teile eines mit 0,15% Nylosanblau N-SGL 200% gefärbten Polyamidgewebes zu, erwärmt es zum Kochen und kocht während 1 Stunde. Am Ende der Kochzeit weisen alle 3 Stücke den gleichen Braunton auf.
Der gleiche Versuch ohne den Zusatz des genannten Gemisches führt nicht zum Ausgleich der 3 Farben.
The main patent no. 543 634 relates to a process for dyeing textiles containing acid-dyeable synthetic fibers in liquors containing water at pH values from 5 to X and in the presence of phenyl sulfones which contain at least one sulfonic acid group bonded to a phenyl radical and which are derived from a ) at least one compound with 6 to 20 carbon atoms, which contains at least one aromatically bound hydroxyl group (compound a). and b) at least one aromatic, non-phenolic compound (compound b) containing 6 to '() C atoms have been obtained using sulfuric acid, which is characterized in that the sulfone comprises 1 to 30% from component (a) and 99 to 70% from component (b)
was produced.
The present additional patent relates to a process in which aryloxypolyglycol ether and ethoxylated higher fatty amines are used in the dyeing process in addition to the phenylsulfones mentioned above.
From DT-OS 1 444 291 and DT-AS 1 132 090 it is already known to use anionic auxiliaries with condensation products from ethylene oxide to fatty amines together in processes for dyeing polyamide textiles with acidic wool dyes to prevent streaking. However, only hydroxyl-free dinaphthylmethane disulfonates (especially their Na salts) are mentioned as anionic auxiliaries.
From CH-PS 465 554 it is also known to use in processes for dyeing textile materials made of synthetic polyamides with water-soluble 1: 2 chromium and cobalt complex dyes mixtures of reaction products of a higher molecular weight fatty amine with ethylene oxide and nonionic dispersants from the series of polyglycol ethers , with the exception of these classes of substances practically no compounds that are effective as electrolytes should be present. However, all of these processes lack practical usability, especially with regard to the speed at which they are drawn up and the leveling properties of the textiles thus dyed.
The mixture of the aryloxypolyglycol ethers and ethoxylated higher fatty amines with the phenyl sulfones of main patent no. 543 634, which is used according to the invention, serves above all to improve the rate of absorption and the color distribution of anionic dyes on the material to be colored. It has a more retarding effect and promotes migration. Despite the retarding effect, the dyes absorb practically completely, so that the mixtures are characterized by a high degree of abundance. Even at 0.5-1%, based on the weight of the goods, an excellent leveling effect is achieved.
With the combination according to the invention of the phenyl sulfones of the main patent with the aryloxypolyglycol ethers and ethoxylated higher fatty amines, colorations are obtained. whose properties are superior to those when using the above-mentioned mixtures of the prior art.
The aryloxypolyglycol ethers to be used according to the invention are, in particular, those of higher alkylphenols, such as, for. B. those of the formula
EMI1.1
in which R represents a C6-C12 alkyl radical, especially a C8 or C9 alkyl or isoalkyl radical, and Rl is hydrogen or has the same meaning as R, or mixtures thereof and x represents a number from 2 () - 6 () .
The ethoxylated higher alkyl fatty amines are those of the formula Rt-NH- (CH2-CH2-O) yH (II) in which the radical R 'is an alkyl radical of Clo-CIZ and y is a number from 3 () - 4 () stands. in question.
The proportion of phenylsulfones in the mixture is approximately 30-S () eJ, the proportion of higher alkylphenol polyglycol ether is approximately 2 () - 30C'r and the proportion of higher alkylfatty amine polyglycol ether is approximately 30-4 (1%, the total amount being 100 have to be.
Anionic dyes are to be understood as those which are able to form colored anions in aqueous solution, for example acidic leveling dyes, whale dyes, 1: 1 and 1: 2 metal complex dyes, chromating dyes, direct and reactive dyes.
The fibers, threads or textiles which can be acidified are to be understood as meaning polycondensation products containing carbonamide groups or basic-modified synthetic materials. The first include the polyamides, such as. B. polycaprolactam, or condensation products of diearonic acids and dihydric amines, such as. B. condensation products from adipic acid and hexamethylenediamine. Basic modified synthetic materials are, for example, polyester condensates containing carbonamide groups.
In general, the mixture is used in amounts of () .2-S wt., .. preferably (1.5-3 wt. Cr; based on the fiber material to be dyed. In addition, other auxiliaries such as sodium sulfate, sodium phosphate , Hexamethylenetetramine or anti-foaming agents may be included.
The following examples are intended to illustrate the invention.
The parts mean parts by weight, the percentages percentages by weight, the temperatures Celsius degrees.
example 1
100 parts of polyamide 66 (knitted) are placed in 3000 parts of a 50 C warming liquor of the following composition: 0.5 part of nylosan orange N-RL 0.1 part of nylosan ruby N-5BL 0.15 part of nylosan evaluator N-SGL 200t.
4 parts (NH4) 2SO4 1 part of a mixture of:
26 parts of a compound of formula II with about 35 (CH2-CH2-O) units
35 parts of a compound of the formula I with about 40 (CH2-CH2-O) units JO parts of Sandogen CN (a compound of the main patent)
The dye is heated to boiling temperature for 30 minutes with stirring. the dye slowly and evenly soaks onto the polyamide material and continues to boil for 45 minutes. After that, the dye bath is practically completely exhausted and the color is even.
An identical color without the addition of the above-mentioned compound of the formulas I and 11 in the mixture mentioned becomes spotty under these conditions.
Example 2
A blind dyebath is prepared which contains 3000 parts of water, 4 parts of ammonium sulfate and 2 parts of the mixture mentioned in Example I. 33 parts of a polyamide fabric dyed with 0.5% nylosan orange N-RL, 33 parts of a 0.1% nylosan ruby N-SBL and 33 parts of a polyamide fabric dyed with 0.15% nylosan blue N-SGL are added to this bath and heated to cook and cook for 1 hour. At the end of the cooking time, all 3 pieces have the same shade of brown.
The same attempt without the addition of the mixture mentioned does not lead to the balance of the 3 colors.
