Abstract
A catalyst system composed of aluminum chlorhydroxide [Al.sub.2 (OH).sub.5 Cl] and hydrogen peroxide [H.sub.2 O.sub.2 ] is disclosed which through synergistic interaction of these components is highly efficient and effective in treatments of cellulose-containing textiles with formaldehyde-amide adduct crosslinking agents. Products with durable-press properties are produced through use of the new catalyst system in treatments employing flash curing conditions, i.e., short processing times at high temperatures, as well as in treatments employing curing temperatures down to 130.degree. C. with longer processing times. Unlike previously known synergistically activated catalyst systems based upon Al.sub.2 (OH).sub.5 Cl, the presently disclosed system utilizes the combination of Al.sub.2 (OH).sub.5 Cl with H.sub.2 O.sub.2, an oxidizing agent, rather than with an acid or a salt with latent acidic or Lewis acid properties.
