Abstract

Compositions for treating cellulosic textiles comprise an aqueous solution of an aminoplastic resin, an acidic catalyst and 0.012% to 0.2% by weight of the resin of hydrogen peroxide which is introduced as hydrogen peroxide or as urea peroxide. The resin may be a polymethylolurea or a polyalkoxymethylurea, a polymethylolethyleneurea or a polyalkoxymethylethyleneurea, or a polymethylolmelamine or a polyalkoxymethylmelamine, those specified being dimethylolethyleneurea, dimethoxymethylurea and dimethylolmelamine. Acidic catalysts specified are morpholine and 2-aminopropanol hydrochlorides, ammonium chloride, diammonium phosphate, ammonium sulphate, zinc fluoborate, and phosphoric, hydrochloric, acetic, oxalic, tartaric and p-toluenesulphonic acids: the compositions may also contain softeners, lubricants and wetting agents. The examples also disclose, for comparative purposes, similar compositions without the peroxide or with the peroxide replaced by potassium or ammonium persulphate.ALSO:A process for the production of soil-resistant and crease-resistant cellulosic fibre products comprises introducing on to the fibres about 1 to 15%, based on the dry weight of the fibres, of a nitrogenous resin which is a polyfunctional methylol or alkoxymethyl urea resin or a polyfunctional methylol or alkoxy-methylmelamine resin, an acidic curing agent and 0.012 to 0.2% based on the weight of the resin, of hydrogen peroxide which is introduced as hydrogen peroxide or as urea peroxide until the nitrogenous resin is cured to a thermoset condition. Nitrogenous resins specified are dimethylolethyleneurea, dimethoxymethylurea and dimethylolmelamine. Many acidic catalysts are specified. The fibrous cellulosic materials may be woven or non-woven fabrics made of cotton, viscose rayon, cuprammonium rayon, jute, ramie or linen which may have been mercerised. They are impregnated with aqueous solutions of the compositions e.g. using padding equipment and squeeze rolls. In examples cotton cloth treated by the process of the invention is compared with cloth similarly treated but omitting the peroxide or replacing it by potassium or ammonium persulphate.
