Definitions
- the present invention relates to a method for the photochemical stabilization of synthetic polyamide fiber materials with water-soluble copper complex dyes.
- Dyed synthetic polyamide fiber material is damaged when exposed to light, especially when exposed to heat; therefore synthetic polyamide fibers are used in some areas of application, such as. B. viewed as car upholstery or sail fabrics, as problem fibers.
- the aim is to improve the photochemical stability of synthetic polyamide fiber materials.
- inorganic or organic copper salts often have the disadvantage that they are insufficiently and unevenly applied to the polyamide fiber and are therefore used in high concentrations and are often used only in an aftertreatment process can be.

- the present invention thus relates to a process for the photochemical stabilization of fiber materials made of synthetic polyamides, which is characterized in that the fiber material is mixed with a mixture of a water-soluble copper complex dye and a fiber-affine, water-soluble, non-chromophoric copper complex of bisazomethines, acylhydrazone, semicarbazones or Treated thiosemicarbazones of aromatic aldehydes or ketones.
- photochemical stabilization here refers to both the light fastness and the maintenance of the mechanical properties of the undyed or dyed polyamide fiber, i.e. Photochemical stabilization against visible and UV light.
- Preferred embodiments of the process according to the invention are characterized in that water-soluble copper complex dyes, in particular water-soluble copper complex azo or azomethine dyes, are used.
- the mixtures mentioned are expediently used in an amount such that 2 to 1000 ⁇ g of copper, in particular 5 to 200 ⁇ g of copper, are added to 1 g of polyamide fiber material.
- a particularly preferred embodiment of the process according to the invention is characterized in that copper complexes of azo or azomethine dyes of the formula which contain water-solubilizing groups where D is a residue of the benzene or naphthalene series, X is a nitrogen atom or the CH group, Y is the HO, CH 3 0 or HOOC group and Y 'is the HO or an amino group, and wherein K is for the Where X is a nitrogen atom, the residue of a coupling component of the benzene, naphthalene or heterocyclic series or the residue of a ketomethylene compound, or, if X is the CH group, K is the residue of an o-hydroxyaldehyde .
- the copper complex dyes come as water-solubilizing groups such.
- Suitable sulfone groups are alkyl sulfone and in particular Cl-4 alkyl sulfone groups.
- N-mono- or N, N-dialkylsulfonamide group is one having one or two C 1-4 -alkyl radicals.
- copper complex dyes with one to two water-solubilizing groups are used in the process according to the invention.
- An interesting embodiment of the method according to the invention is characterized in that a copper complex dye of the formula used, in which A is an optionally substituted carboxyphenyl or sulfophenyl radical, R, hydrogen or C 1-4 alkyl, X is a nitrogen atom or the CH group and K, in the event that X is a nitrogen atom, the residue of a coupling component of the benzene, Naphthalene, pyrazolone, aminopyrazole, acetoacetanilide, 2,4-dioxyquinoline, pyridone or pyridine series, or, if X is the CH group, is the remainder of an o-hydroxybenzaldehyde, and the ring B optionally z.
- B. may be further substituted by chlorine or nitro.
- azo dyes of the formula (1) have been described in the literature.

- a process variant for the preparation of the copper complex of an azomethine dye of the formula (1) is characterized in that the copper complex can also be prepared with a mixture of the amine of the formula (3) and an o-hydroxyaldehyde instead of with the azomethine of the formula (1).
- the metal complexes are prepared by methods known per se in an aqueous or organic medium.
- copper salts such as. B. copper sulfate and copper nitrate.
- the freshly precipitated hydroxides can also be used.
- the reaction is carried out in the weakly acidic to alkaline range.
- reaction is carried out with heating, e.g. B. slightly below the boiling point of the solvent used.
- Preferred copper complexes of bisazomethines, acylhydrazones, semicarbazones and thiosemicarbazones of aromatic aldehydes or ketones are those which contain sulfonic acid groups. They are readily water-soluble and also have an excellent affinity for polyamide fibers. Such complexes are therefore effective even in small amounts. In addition, it has been shown that they not only increase the lightfastness of the dyed polyamide material, but also generally protect the polyamide fiber against photochemical degradation and thus largely maintain its mechanical properties, such as tear resistance and elasticity.
- Bisazomethines of aromatic aldehydes and ketones are understood to mean Schiff bases of aliphatic, cycloaliphatic or aromatic diamines, the aldehydes and ketones having an OH group in the o-position to the formyl or acyl radical.
- the bond with the copper atom takes place via these two OH groups and the two nitrogen atoms in the bisazomethine part. Accordingly, these are tidentate ligands.

Description
Die vorliegende Erfindung betrifft ein Verfahren zur fotochemischen Stabilisierung von synthetischen Polyamidfasermaterialien mit wasserlöslichen Kupferkomplexfarbstoffen.The present invention relates to a method for the photochemical stabilization of synthetic polyamide fiber materials with water-soluble copper complex dyes.
Gefärbtes synthetisches Polyamidfasermaterial wird bei Belichtung insbesondere bei gleichzeitiger Wärmeeinwirkung geschädigt; daher werden synthetische Polyamidfasern in einigen Anwendungsbereichen, wie z. B. als Autopolster- oder Segelstoffe, als Problemfasern angesehen.Dyed synthetic polyamide fiber material is damaged when exposed to light, especially when exposed to heat; therefore synthetic polyamide fibers are used in some areas of application, such as. B. viewed as car upholstery or sail fabrics, as problem fibers.
Den heutigen Anforderungen entsprechend wird eine Verbesserung der fotochemischen Stabilität von synthetischen Polyamidfasermaterialien angestrebt.In line with today's requirements, the aim is to improve the photochemical stability of synthetic polyamide fiber materials.
Die Verwendung von Kupfersalzen, wie z. B. Kupfersulfat, zur Verbesserung der Lichtechtheit von Färbungen auf Polyamidfasern mit Metallkomplexfarbstoffen ist allgemein bekannt; verwiesen wird auf das in der US-A-3 592 584 offenbarte Verfahren zur Verbesserung der Egalität und der Lichtechtheit von Färbungen auf Polyamidfasern durch Behandlung der Fasern mit Färbeflotten enthaltend Kupferkomplexfarbstoffe, bestimmte Färbereihilfsmittel sowie eine Mischung aus dem Natriumsalz der Ethylendiamintetraessigsäure und wasserfreiem Kupfersulfat, sowieThe use of copper salts, such as. B. copper sulfate, to improve the lightfastness of dyeings on polyamide fibers with metal complex dyes is generally known; Reference is made to the method disclosed in US Pat. No. 3,592,584 for improving the levelness and lightfastness of dyeings on polyamide fibers by treating the fibers with dye liquors containing copper complex dyes, certain dyeing aids and a mixture of the sodium salt of ethylenediaminetetraacetic acid and anhydrous copper sulfate, and
auf den Artikel von I.B. HANES in American Dyestuff Reporter 3 (1980), Seiten 19 und 20. Anorganische oder auch organische Kupfersalze haben jedoch vielfach den Nachteil, dass sie nur ungenügend und ungleichmässig auf die Polyamidfaser aufziehen, daher in hohen Konzentrationen verwendet werden und oft nur in einem Nachbehandlungsverfahren verwendet werden können.to the article by I.B. HANES in American Dyestuff Reporter 3 (1980), pages 19 and 20. However, inorganic or organic copper salts often have the disadvantage that they are insufficiently and unevenly applied to the polyamide fiber and are therefore used in high concentrations and are often used only in an aftertreatment process can be.
Man hat daher versucht, das Kupfer in Form von Verbindungen einzusetzen, die eine Affinität zur Polyamidfaser aufweisen. So wird z. B. in der EP-0 018 775 Kupferphosphat empfohlen, das sich ähnlich wie ein Dispersfarbstoff verhalten soll und entsprechend auf die Nylonfaser aufzieht. Derartige bekannte Kupferverbindungen haben jedoch im allgemeinen eine zu geringe Wasserlöslichkeit, was sich ebenfalls negativ auf den Ausziehgrad auswirkt. Darüberhinaus führt das im Färbebad verbleibende Kupfer zu einer starken Abwasserbelastung.Attempts have therefore been made to use the copper in the form of compounds which have an affinity for the polyamide fiber. So z. B. is recommended in EP-0 018 775 copper phosphate, which should behave similar to a disperse dye and absorbs accordingly on the nylon fiber. However, such known copper compounds generally have too little water solubility, which likewise has a negative effect on the degree of exhaustion. In addition, the copper remaining in the dye bath leads to a high level of wastewater pollution.
Die der vorliegenden Erfindung zugrundeliegende Aufgabe war es, ein Verfahren zur fotochemischen Stabilisierung von synthetischen Polyamidfasermaterialien zu finden, welches die vorstehend beschriebenen Nachteile nicht aufweist und den heutigen Anforderungen genügt.The object underlying the present invention was to find a process for the photochemical stabilization of synthetic polyamide fiber materials which does not have the disadvantages described above and which meets today's requirements.
Diese Aufgabe wird dadurch gelöst, dass man anstelle der bekannten, wenig faseraffinen bzw. schlecht wasserlöslichen Kupferverbindungen, wasserlösliche Kupferkomplexfarbstoffe verwendet. Diese Farbstoffe sind faseraffin und enthalten wasserlöslichmachende Gruppen.This object is achieved in that water-soluble copper complex dyes are used instead of the known copper compounds which have little affinity for fibers or are poorly water-soluble. These dyes are fiber-affine and contain water-solubilizing groups.
Gegenstand der vorliegenden Erfindung ist somit ein Verfahren zur fotochemischen Stabilisierung von Fasermaterialien aus synthetischen Polyamiden, welches dadurch gekennzeichnet ist, dass man das Fasermaterial mit einer Mischung von einem wasserlöslichen Kupferkomplexfarbstoff und einem faseraffinen, wasserlöslichen, nicht-chromophoren Kupferkomplex von Bisazomethinen, Acylhydrazonen, Semicarbazonen oder Thiosemicarbazonen aromatischer Aldehyde oder Ketone behandelt.The present invention thus relates to a process for the photochemical stabilization of fiber materials made of synthetic polyamides, which is characterized in that the fiber material is mixed with a mixture of a water-soluble copper complex dye and a fiber-affine, water-soluble, non-chromophoric copper complex of bisazomethines, acylhydrazone, semicarbazones or Treated thiosemicarbazones of aromatic aldehydes or ketones.
Der Ausdruck fotochemische Stabilisierung bezieht sich im vorliegenden sowohl auf die Lichtechtheit, wie auch auf die Erhaltung der mechanischen Eigenschaften der ungefärbten oder gefärbten Polyamidfaser, d.h. fotochemische Stabilisierung gegen sichtbares und UV-Licht.The term photochemical stabilization here refers to both the light fastness and the maintenance of the mechanical properties of the undyed or dyed polyamide fiber, i.e. Photochemical stabilization against visible and UV light.
Mit dem erfindungsgemässen Verfahren werden gefärbte, synthetische Polyamidmaterialien von sehr hoher fotochemischer Stabilität vor allem bei gleichzeitiger Licht- und Wärmeeinwirkung erhalten.With the process according to the invention, colored, synthetic polyamide materials of very high photochemical stability are obtained, in particular with simultaneous exposure to light and heat.

Eine Verfahrensvariante zur Herstellung des Kupferkomplexes eines Azomethinfarbstoffes der Formel (1) ist dadurch gekennzeichnet, dass man den Kupferkomplex statt mit dem Azomethin der Formel (1) auch mit einem Gemisch des Amins der Formel (3) und einem o-Hydroxyaldehyd herstellen kann. Die Herstellung der Metallkomplexe geschieht nach an sich bekannten Methoden in einem wässrigen oder organischen Medium. Als Kupfer abgebende Mittel verwendet man Kupfersalze, wie z. B. Kupfersulfat und Kupfernitrat. Auch die frisch gefällten Hydroxyde können verwendet werden. Die Umsetzung wird im schwach sauren bis alkalischen Bereich durchgeführt. Man arbeitet beispielsweise mit Kupfersulfat in wässrigem Medium in Gegenwart von Natriumacetat oder Ammoniak oder mit Kupfernitrat in Gegenwart von Soda in einem organischen Medium wie Methylcellosolve.A process variant for the preparation of the copper complex of an azomethine dye of the formula (1) is characterized in that the copper complex can also be prepared with a mixture of the amine of the formula (3) and an o-hydroxyaldehyde instead of with the azomethine of the formula (1). The metal complexes are prepared by methods known per se in an aqueous or organic medium. As a copper releasing agent, copper salts, such as. B. copper sulfate and copper nitrate. The freshly precipitated hydroxides can also be used. The reaction is carried out in the weakly acidic to alkaline range. One works, for example, with copper sulfate in an aqueous medium in the presence of sodium acetate or ammonia or with copper nitrate in the presence of soda in an organic medium such as methyl cellosolve.
Im allgemeinen wird die Reaktion unter Erwärmen durchgeführt, z. B. etwas unterhalb des Siedepunktes des verwendeten Lösungsmittels.In general, the reaction is carried out with heating, e.g. B. slightly below the boiling point of the solvent used.
Als Kupferkomplexe von Bisazomethinen, Acylhydrazonen, Semicarbazonen und Thiosemicarbazonen aromatischer Aldehyde oder Ketone kommen vorzugsweise solche in Betracht, die Sulfonsäuregruppenhaltig sind. Sie sind gut wasserlöslich und haben zudem eine ausgezeichnete Affinität zur Polyamidfaser. Solche Komplexe sind daher bereits in geringen Mengen wirksam. Zudem hat sich gezeigt, dass sie nicht nur die Lichtechtheit des gefärbten Polyamidmaterials erhöhen, sondern ganz allgemein die Polyamidfaser gegen fotochemischen Abbau schützen und so deren mechanische Eigenschaften, wie Reissfestigkeit und Elastizität weitgehend erhalten..Preferred copper complexes of bisazomethines, acylhydrazones, semicarbazones and thiosemicarbazones of aromatic aldehydes or ketones are those which contain sulfonic acid groups. They are readily water-soluble and also have an excellent affinity for polyamide fibers. Such complexes are therefore effective even in small amounts. In addition, it has been shown that they not only increase the lightfastness of the dyed polyamide material, but also generally protect the polyamide fiber against photochemical degradation and thus largely maintain its mechanical properties, such as tear resistance and elasticity.
Unter Bisazomethinen aromatischer Aldehyde und Ketone werden hier Schiff'scheBasen von aliphatischen, cycloaliphatischen oder aromatischen Diaminen verstanden, wobei die Aldehyde und Ketone in o-Stellung zum Formyl- bzw. Acylrest eine OH-Gruppe aufweisen. Die Bindung mit dem Kupferatom erfolgt über diese beiden OH-Gruppen und die beiden Stickstoffatome im Bisazomethinteil. Es handelt sich demnach hier um vierzähnige Liganden. Die Liganden enthalten eine oder auch mehrere Sulfogruppen, die sich im Aldehyd- bzw. Ketonteil und/oder in der Bisazomethinbrücke befinden.Bisazomethines of aromatic aldehydes and ketones are understood to mean Schiff bases of aliphatic, cycloaliphatic or aromatic diamines, the aldehydes and ketones having an OH group in the o-position to the formyl or acyl radical. The bond with the copper atom takes place via these two OH groups and the two nitrogen atoms in the bisazomethine part. Accordingly, these are tidentate ligands. The ligands contain one or more sulfo groups which are located in the aldehyde or ketone part and / or in the bisazomethine bridge.

In dem erfindungsgemässen Verfahren ist das Verhältnis von Kupferkomplexfarbstoff: faseraffinem, wasserlöslichem, nicht-chromophorem Kupferkomplex, vorzugsweise 99 :1 bis 10 : 90.In the process according to the invention, the ratio of copper complex dye: fiber-affine, water-soluble, non-chromophoric copper complex is preferably 99: 1 to 10:90.
Das Mischungsverhältnis hängt dabei von der Anzahl der verwendeten Kupferkomplexfarbstoffe und der gewünschten Farbtiefe der Färbungen ab.The mixing ratio depends on the number of copper complex dyes used and the desired color depth of the dyeings.
Die Kupferkomplexe der angegebenen Formeln (5), (6) und (7) und deren Alkalimetallsalze, wie Kalium- und Lithiumsalze, und insbesondere deren Natriumsalze werden nach bekannten Methoden erhalten.The copper complexes of the formulas (5), (6) and (7) given and their alkali metal salts, such as potassium and lithium salts, and in particular their sodium salts, are obtained by known methods.
Die Metallkomplexe der Formel (5) sind beispielsweise auf zwei verschiedenen Wegen zugänglich. So kann man einmal den Aldehyd oder das Keton zunächst metallisieren und anschliessend mit dem entsprechenden Diamin zum fertigen Komplex der Formel (5) umsetzen. Man kann aber auch zunächst den Liganden aus Aldehyd bzw. Keton und Diamin synthetisieren und anschliessend die Metallisierung durchführen.The metal complexes of the formula (5) are accessible, for example, in two different ways. So you can first metallize the aldehyde or the ketone and then react with the corresponding diamine to the finished complex of formula (5). However, one can also first synthesize the ligand from aldehyde or ketone and diamine and then carry out the metallization.
Die Acylhydrazone, die Liganden der Komplexe (6), werden beispielsweise durch Umsetzen des Aldehyds bzw. Ketons mit dem entsprechenden Monoacylhydrazin und anschliessende Metallisierung gewonnen. Ganz analog lassen sich auch die Komplexe der Formel (7) herstellen. Mindestens eines der Ausgangsprodukte zur Herstellung der Verbindungen der Formel (5), (6) und (7) muss eine Sulfonsäuregruppe enthalten.The acylhydrazones, the ligands of the complexes (6), are obtained, for example, by reacting the aldehyde or ketone with the corresponding monoacylhydrazine and subsequent metallization.

Als Säurefarbstoffe kommen z. B. metallfreie Mono- oder Polyazofarbstoffe, 1 : 2-Chrom- oder 1 : 2-Kobaltkomplexazofarbstoffe, Anthrachinon-, Dioxazin-, Phthalocyanin-, Nitroaryl- oder Stilbenfarbstoffe in Betracht, die mindestens eine Säuregruppe, wie z. B. Carboxyl oder vorzugsweise eine Sulfonsäuregruppe aufweisen.As acid dyes come e.g. B. metal-free mono- or polyazo dyes, 1: 2-chromium or 1: 2-cobalt complex azo dyes, anthraquinone, dioxazine, phthalocyanine, nitroaryl or stilbene dyes into consideration, which have at least one acid group, such as.

Polyamid-6, Polyamid-66 oder auch Polyamid-12, verwendet.As a polyamide fiber material in the inventive method such synthetic polyamides, such as. B. polyamide-6, polyamide-66 or polyamide-12 used.
Grundsätzlich kann das Polyamidfasermaterial in den verschiedensten Verarbeitungsformen vorliegen, wie z. B. Faser, Garn, Gewebe oder Gewirke, insbesondere textiles Fasermaterial.Basically, the polyamide fiber material can be in a wide variety of processing forms, such as. B. fiber, yarn, woven or knitted fabric, in particular textile fiber material.
Die in dem erfindungsgemässen Verfahren verwendeten sulfogruppenhaltigen Farbstoffe liegen entweder in der Form ihrer freien Sulfonsäure oder vorzugsweise als deren Salze vor.The dyes containing sulfo groups used in the process according to the invention are present either in the form of their free sulfonic acid or preferably as their salts.
Als Salze kommen beispielsweise die Alkali-, Erdalkali- oder Ammoniumsalze oder die Salze eines organischen Amins in Betracht. Als Beispiele seien die Natrium-, Lithium-, Kalium- oder Ammoniumsalze oder das Salz des Triäthanolamins genannt.Examples of suitable salts are the alkali metal, alkaline earth metal or ammonium salts or the salts of an organic amine.

Ein besonders hervorzuhebender Vorteil des erfindungsgemässen Verfahrens ist, dass im Vergleich zu bisher bekannten Verfahren zur fotochemischen Stabilisierung von synthetischen Polyamidfasermaterialien keine Vor- oder Nachbehandlung des Fasermaterials erforderlich ist.A particularly noteworthy advantage of the method according to the invention is that, compared to previously known methods for the photochemical stabilization of synthetic polyamide fiber materials, no pre- or post-treatment of the fiber material is required.
Die gemäss dem erfindungsgemässen Verfahren verwendeten Mischungen von Kupferkomplexfarbstoffen mit den nicht-chromophoren Kupferkomplexverbindungen, zeigen den Vorteil, dass unabhängig von der gewünschten Farbtiefe der mit den Kupferkomplexfarbstoffen enthaltenen Färbungen, ein konstanter Kupfergehalt der Faser eingestellt werden kann, d.h. die Schutzwirkung unterliegt keinen nuancebedingten Schwankungen.The mixtures of copper complex dyes with the non-chromophoric copper complex compounds used in accordance with the process according to the invention have the advantage that, regardless of the desired depth of color of the dyeings contained with the copper complex dyes, a constant copper content of the fiber can be set, i.e. the protective effect is not subject to nuance-related fluctuations.
Die Prüfung der fotochemischen Stabilisierung des Fasermaterials erfolgt z. B. in einem Fade-Ometer bei einer "Black panel temperature" von 83° C (Heissbelichtung) oder durch Belichtung in einer Xenotest-Apparatur gemäss DIN 75 202, Entwurf (= Fakra, Heissbelichtung) oder SN (Schweizerische-Norm)-ISO 105 B 02 (= Xenon) mit anschliessender Prüfung der Reissfestigkeit und Dehnung des Materials gemäss SNV-Norm 97 461 und 198 461.The examination of the photochemical stabilization of the fiber material is carried out e.g. B. in a fade-ometer at a "black panel temperature" of 83 ° C (hot exposure) or by exposure in a Xenotest apparatus according to DIN 75 202, draft (= Fakra, hot exposure) or SN (Swiss standard) -ISO 105 B 02 (= Xenon) with subsequent testing of the tensile strength and elongation of the material according to SNV standards 97 461 and 198 461.
