Estimating the term…
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 catalyzed on the textile.
