Patent

CA 2342616

A method of treating a textile such as a laundry fabric is provided, in which the textile is contacted with an organic substance which forms a complex with a transition metal, whereby the complex catalyses bleaching of the textile by atmospheric oxygen after the treatment. The organic substance may be used in dry form, or in a liquor that is then dried, such as an aqueous spray-on fabric treatment fluid or a wash liquor for laundry cleaning, or a non-aqueous dry cleaning fluid or spray- on aerosol fluid. The method can confer cleaning benefits to the textile after the treatment. Also provided is a dry textile having an organic substance applied or deposited thereon, whereby bleaching by atmospheric oxygen is catalysed on the textile.

L'invention concerne un procédé de traitement d'un textile, notamment d'un tissu lavable, lequel procédé consiste à mettre le textile au contact d'une substance organique formant un complexe avec un métal de transition, ledit complexe catalysant le blanchiment du textile par l'oxygène de l'air après le traitement. La substance organique peut être utilisée sous forme anhydre, ou sous forme d'une liqueur, déshydratée par la suite, telle qu'un fluide aqueux de traitement des tissus à vaporiser ou une liqueur de lavage destinée au lavage en machine, ou un fluide non aqueux de nettoyage à sec ou un fluide aérosol à vaporiser. Le procédé de l'invention permet d'améliorer le nettoyage du textile après le traitement. L'invention concerne également un textile sec sur lequel on applique ou on dépose une substance organique pour catalyser un blanchiment par l'oxygène de l'air sur ledit textile.
