Abstract
Description
Die vorliegende Erfindung betrifft ein Verfahren zur fotochemischen Stabilisierung von ungefärbten und zu färbenden Lederimitaten, ein Mittel zur Ausführung des Verfahrens sowie die damit behandelten Lederimitate.The present invention relates to a method for the photochemical stabilization of undyed and dyed imitations of leather, an agent for carrying out the method and the imitations of leather treated with it.
Hochwertige Syntheseleder auf der Basis von Polyurethan/Polyamid und Färbungen dieser Substrate werden unter Einwirkung von Licht und besonders bei gleichzeitiger Wärmestrahlung geschädigt. So ist die fotochemische Stabilität von Lederimitaten, die mit ausgewählten Farbstoffen gefärbt sind, für zahlreiche Anwendungen, beispielsweise bei der Automobilinnenausstattung nicht ausreichend.High-quality synthetic leather based on polyurethane / polyamide and the colors of these substrates are damaged under the influence of light and especially with simultaneous heat radiation. For example, the photochemical stability of imitations of leather that are dyed with selected dyes is not sufficient for numerous applications, for example in automotive interiors.
Es mangelt daher nicht an Versuchen, Lederimitate und deren Färbungen gegen Licht- und Wärmeeinwirkung mit Hilfe von UV-Absorbern zu schützen. Bei diesen bekannten Verfahren werden die Lichtschutzmittel in organische Lösungen der Polymerkomponenten der synthetischen Leder eingarbeitet oder als Schutzschicht zusammen mit einem organischen Lösungsmittel auf das Lederimitat aufgetragen. In der JP 58/163 785 werden beispielsweise lichtstabile Kunstleder beschrieben, die mit einem UV-Absorber beschichtet werden, der in einem organischen Lösungsmittel gelöst ist.There is therefore no shortage of attempts to protect imitations of leather and their dyeings against the effects of light and heat with the help of UV absorbers. In these known processes, the light stabilizers are incorporated into organic solutions of the polymer components of the synthetic leather or applied as a protective layer to the imitation leather together with an organic solvent. JP 58/163 785, for example, describes light-stable synthetic leather which is coated with a UV absorber which is dissolved in an organic solvent.
Es wurde nun gefunden, dass ungefärbte und zu färbende Lederimitate auch aus wässrigen Flotten stabilisiert werden können.It has now been found that undyed and dyed imitations of leather can also be stabilized from aqueous liquors.
Das erfindungsgemässe Verfahren ist dadurch gekennzeichnet, dass man das ungefärbte oder zu färbende Lederimitat in einer wässrigen Flotte behandelt, das ein Lichtschutzmittel enthält.The process according to the invention is characterized in that the undyed or imitation leather to be dyed is treated in an aqueous liquor which contains a light stabilizer.
Als bevorzugtes Lichtschutzmittel wird erfindungsgemäss ein sterisch gehindertes Amin verwendet, das in seinem Molekül mindestens eine Gruppe der Formel I enthält,
Solche Lichtschutzmittel können niedermolekular (MG < 700) oder höhermolekular (Oligomere, Polymere) sein. Bevorzugt tragen diese Gruppen einen oder zwei polare Substituenten in 4-Stellung oder ein polares Spiro-Ringsystem ist an die 4-Stellung gebunden.Such light stabilizers can be low molecular weight (MW <700) or higher molecular weight (oligomers, polymers). These groups preferably carry one or two polar substituents in the 4-position or a polar spiro ring system is bonded to the 4-position.
Von besonderem Interesse sind sterisch gehinderte Amine der Formel II

Unter Lederimitaten, die fotochemisch stabilisiert werden, werden synthetische Vliese aus superfeinen Fasern verstanden, wie sie beispielsweise in Textiltechnik 37(2), Seite 118, (1987) beschrieben sind.Imitations of leather that are stabilized photochemically are understood to mean synthetic nonwovens made from superfine fibers, as described, for example, in Textile Technology 37 (2), page 118, (1987).
Es können auch Lederimitate verwendet werden, die vor der Behandlung mit dem Lichtschutzmittel optisch aufgehellt sind.Imitations of leather can also be used, which are optically lightened before treatment with the light stabilizer.
Lederimitate, in deren Vliese Russpigmente enthalten sind, kommen ebenfalls zum Einsatz.Imitation leather, in the fleece of which there are soot pigments, are also used.
Das erfindungsgemässe Verfahren eignet sich besonders zur fotochemischen Stabilisierung von Lederimitaten, die in grossem Masse Licht, vor allem Licht und Hitze ausgesetzt sind und z.B. in der Automobilinnenausstattung Verwendung finden.The process according to the invention is particularly suitable for the photochemical stabilization of imitations of leather which are exposed to a large extent to light, especially light and heat and e.g. used in automotive interiors.
Die Färbung erfolgt in üblicher Weise z.B. mit Metallkomplexfarbstoffen oder auch mit Anthrachinonfarbstoffen oder Azofarbstoffen. Als Metallkomplexfarbstoffe werden die bekannten Typen, insbesondere die 1:2-Chrom- oder 1:2-Kobaltkomplexe von Mono- oder Disazo- oder -azomethinfarbstoffen eingesetzt, die in der Literatur in grosser Zahl beschrieben sind. Neben diesen kommen natürlich auch Farbstoffe aus anderen Farbstoffklassen in Frage, wie z.B. Dispersion- oder auch Küpenfarbstoffe.The dyeing is carried out in the customary manner, for example using metal complex dyes or also using anthraquinone dyes or azo dyes. The known types, in particular the 1: 2 chromium or 1: 2 cobalt complexes of mono- or disazo or -azomethine dyes, which are described in large numbers in the literature, are used as metal complex dyes. In addition to these, dyes from other classes of dyes are of course also possible, such as disperse dyes or vat dyes.
