Abstract

L'invention concerne un procédé de blanchiment pour textiles tachés, consistant à prétraiter le textile taché avant le lavage, à l'aide d'une composition de prétraitement qui comprend un ligand formant un complexe de métal de transition en tant que catalyseur de blanchiment. Ce complexe catalyse le blanchiment des taches par l'oxygène atmosphérique. La composition de prétraitement comprend de préférence un complexe de fer contenant le ligand N,N-bis (pyridin-2-yl-méthyle)-1,1-bis(pyridin-2-yl)-1-aminoéthane. La composition de prétraitement et/ou la lessive de lavage sont sensiblement exempts d'agent de blanchiment peroxydé ou d'un système à base de peroxy ou générant du peroxy. Ce prétraitement permet un blanchiment amélioré des taches ou couvrant un profil de taches plus étendu.
