Abstract (en)

[origin: US5069681A] There is disclosed a process for the photochemical stabilization of dyed polyamide fibre materials, which comprises treating the dyed material with an aqueous foamed composition which contains at least a non-dyeing copper complex of bisazomethines, acylhydrazones, semicarbazones or thiosemicarbazones of aromatic aldehydes or ketones or oximes. By means of the process of this invention it is possible to prevent wastewater from being contaminated with copper-containing impurities.

Abstract (de)

Beschrieben wird ein Verfahren zum photochemischen Stabilisieren von gefärbten textilen Fasermaterialien, das dadurch gekennzeichnet ist, dass man das gefärbte Fasermaterial mit einer verschäumten wässrigen Zubereitung behandelt, welche mindestens (a) einen nicht färbenden Kupferkomplex von Bisazomethinen, Acylhydrazonen, Semicarbazonen oder Thiosemicarbazonen aromatischer Aldehyde oder Ketone oder Oximen enthält. Mit den erfindungsgemässen Verfahren gelingt es, Abfälle an kupferhaltigen Verunreinigungen im Abwasser zu verhindern.
