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.

Method for the application of durable press finishes to textile components via the use of hydrophobic bleaching preparation

This invention relates to polyol fatty acid polyester compositions having improved physiological properties, organoleptic properties (i.e. mouth feel), liquid/solid stability and chemical stability. These polyol fatty acid polyesters are characterized in that (a) not more than about 0.6% of the fatty acid groups contain three or more double bonds, not more than about 20% of the fatty acid groups contain two or more double bonds, and not more than about 35% of the fatty acid double bonds are trans double bonds; (b) the polyesters have an iodine value between about 15 and about 60; and (c) the solid fat content/liquid solid stability ratio is not greater than 0.25. This invention also relates to a process for preparing these improved polyol polyester compositions.
