Abstract

517,890. Treating textiles with liquids; resinous condensation products. COURTAULDS, Ltd., and BOULTON, J. Aug. 15, 1938, No. 24023. [Classes 2 (iii) and 15 (ii)] The resistance to creasing of cellulosic textile material is improved and the material is also delustred by treating it with a cold aqueous solution containing two distinct water-soluble urea-formaldehyde precondensates to which solution there has been added, shortly before the treatment of the material, an acid or acidforming substance which initiates and assists the process of rendering insoluble one of the precondensates in the cold, but which only causes the other precondensate to become insoluble when heat is applied, and subsequently drying and heating the so-treated material. The first precondensate rapidly becomes deposited on the fibres during the cold treatment and is distributed in the form of fine particles which cause delustring. The other precondensate is converted into a synthetic resin during the heat treatment and gives the anticrease effect. In an example, urea is shaken with formaldehyde solution and strong caustic soda is added to give a pH value of 7.5-8. Ammonium hydroxide is added and the solution is refluxed with vigorous heating for a few minutes followed by cooling. A clear syrup is obtained. Another precondensate is prepared by mixing urea and formaldehyde and adding caustic soda to give a pH of 9. The solution is shaken for several hours at room temperature. The two precondensates are mixed together with lactic acid, ammonium sulphate and water. Viscose rayon crepe is padded with the cold solution. It is run on a mangle bowl or hung in the air till delustring is observed. It is then dried and subsequently heated to 145‹ C. Specification 499,207 is referred to.
