A method for the application of durable press to textiles via the pre-treatment bleaching of a non-finished textile component followed by the application of a durable press finish is provided. The method comprises the steps of treating a non-finished textile component in an aqueous bleaching solution of hydrogen peroxide and a hydrophobic activator or hydrophobic peracid for a time sufficient to bleach the textile component followed by application of the durable press finish preferably via immersion in an aqueous solution of formaldehyde, a cross lining catalyst and a silicone elastomer forming material or a solution of alkylene urea and a crosslinking catalyst. Preferred bleach activators include the alkanoyloxybenzene sulfonates and in particular noanoyloxybenzene sulfonate. The method allows significant savings in both energy and time due to the lower bleaching temperatures possible via the present method as opposed to conventional peroxide processing.
A method for the treatment of a non-finished textile component comprising the steps of providing a non-finished textile component, saturating said textile component with an aqueous hydrophobic bleaching solution comprising hydrogen peroxide and a hydrophobic bleach activator or hydrophobic peracid, and allowing said bleaching solution to remain in contact with said textile component for a period of time sufficient to bleach said textile component followed by finishing said textile component to provide durable press to said textile component.
