  • Patent number: 4105403
    Abstract: To the surface of knitted cotton fabrics is applied from 20 to 90% wet add-on of crosslinking agent in a novel geometric pattern by any of several techniques including kiss-roll padding, printing, or transferring the solution of crosslinking agent from impregnated material to the surface of the knitted fabric, followed by drying and curing the moist textile at elevated temperatures, and finally by washing the cured fabric to effect differential shrinkage of the fabric in the applied design, which novel shrinkage in the fabric is fixed through the life of the fabric and is stable through subsequent launderings.

  • Patent number: 4102840
    Abstract: This invention describes a process for the manufacture of condensation products and compositions obtained thereby. The condensation products are prepared by the reaction of 2 to 3 moles of urea with 0,9 to 1,1 mole of formaldehyde and 1 mole of isobutyraldehyde in the presence of 0,2 to 1,0 equivalent of strong acids and 4 to 18 moles of water. The pH-value of the resulting products is adjusted to 7 to 9,5 and the water is partially to almost completely removed. Then the products are methylolated with 3 to 4 moles of formaldehyde. Finally the condensation products are etherified with low alcohols in usual manner. Used singly or together with other N-methylol compounds and their ethers with low alcohols, the products are useful compositions which are capable of rendering cellulosic textile materials and blends with synthetic fibres crease- and shrinkproof.

  • Patent number: 4039282
    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.

  • Patent number: 3948600
    Abstract: In mild cure finishing, strong catalysts are required because of the modest curing conditions employed in the process. Suitable catalysts for mild cure finishing include strong inorganic acids, strong organic acids, active inorganic complexes, salt/acid combinations, and salts that are strong Lewis acids (i.e, certain metal salts). Ammonium salts of inorganic acids, although often used in other types of treatments for producing wrinkle resistant textiles, are not satisfactory catalysts for mild cure finishing. Unexpectedly and surprisingly, it has been discovered that ammonium salts of certain, but not all, sulfonic acids can serve as effective catalysts for mild cure finishing of cellulose-containing fabrics to produce wrinkle resistance and durable press properties. Among ammonium sulfonates which provide the catalysis needed for mild cure finishing are ammonium methanesulfonate, ammonium carboxymethanesulfonate (NH.sub.4 O.sub.3 SCH.sub.2 COOH), ammonium benzenesulfonate, and ammonium p-toluenesulfonate.
