USE OF UV ABSORBERS FOR SUPPRESSING THE FLUORESCENCE OF TEXTILE FIBRE MATERIALS TREATED WITH FLUORESCENT WHITENING AGENTS

The present invention relates to a process for inhibiting (quenching) the effect of fluorescent whitening agents on cellulosic textile fibre materials treated, being treated or to be treated with fluorescent whitening agents, by the application of certain triazine-based ultra-violet absorption agent...

Beschreibung
Zusammenfassung:	The present invention relates to a process for inhibiting (quenching) the effect of fluorescent whitening agents on cellulosic textile fibre materials treated, being treated or to be treated with fluorescent whitening agents, by the application of certain triazine-based ultra-violet absorption agent (UVAs), preferably those of formula (10) in which M, n1, n2, R9 and R10 are as defined in claim 2 and to the material so treated and also to processes for decontaminating detergent manufacturing apparatus and recycled industrial laundry water containing residual fluorescent whitening agent (FWAs). L'invention concerne un procédé permettant de neutraliser (désactiver) l'effet des agents de blanchiment fluorescents sur des matériaux en fibres textiles cellulosiques avant, pendant ou après le traitement au moyen d'agents de blanchiment fluorescents, par l'application de certains agents d'absorption ultraviolets (UVA) à base de triazine, de préférence, ceux de la formule (10) ci-dessous, dans laquelle M, n1, n2, R9 et R10 sont définis tels que dans la revendication n DEG 2. L'invention concerne également les matériaux ainsi traités ainsi que des procédés de décontamination de l'eau recyclée de blanchisserie industrielle et de dispositifs de fabrication à base de détergents, contenant des agents de blanchiment fluorescents résiduels.
