Abstract

L'invention se rapporte au blanchiment catalytique de substrats, notamment de tissus pour blanchissage, avec de l'oxygène atmosphérique ou de l'air. L'invention concerne un procédé de blanchiment d'un substrat, qui consiste à appliquer sur le substrat, dans un milieu aqueux, un ligand spécifié d'une classe sélectionnée, qui forme avec un métal de transition un complexe utilisant l'oxygène atmosphérique pour catalyser le blanchiment du substrat. Elle concerne également une composition de blanchiment aqueuse sensiblement dépourvue d'agent de blanchiment peroxygéné ou d'un système de blanchiment à base de peroxy ou générateur de peroxy. L'invention concerne en outre un procédé de traitement d'un textile, tel qu'un tissu pour blanchissage, qui met en oeuvre un complexe utilisant l'oxygène atmosphérique pour catalyser le blanchiment du textile après traitement. Le catalyseur peut être utilisé sous forme de poudre ou dans une liqueur qui est ensuite séchée, telle qu'un fluide aqueux d'apprêt thermique applicable par pulvérisation, ou une liqueur de lavage pour blanchisserie, ou un fluide non aqueux de nettoyage à sec, ou encore un fluide aérosol applicable par pulvérisation. Le procédé peut conférer des qualités de lavage au textile après traitement. L'invention concerne enfin un textile sec sur lequel un catalyseur est appliqué ou déposé, et dont le blanchiment est catalysé avec de l'oxygène atmosphérique.
