Abstract

An aqueous preparation suitable for treating textile fibres is made from an aqueous solution containing a catalyst and a urea-formaldehyde condensation product of a degree of condensation in which it has a low water tolerance (i.e. it is sufficiently hydrophobic to be thrown out of solution before, on dilution, the concentration falls to 10%), by diluting the solution with water in the presence of a hydrophyllic colloid so that the resin is thrown out of solution into intimate association with the colloid. The mol. ratio of urea to formaldehyde in the condensation product is preferably between 1 : 1,5 and 1 : 2, and the ratio of resin to colloid is preferably within the range of 1 : 4 and 4 : 1, although in the case of highly viscous colloids it may be as high as 15 : 1. Specified hydrophyllic colloids are starch, gelatine, carboxymethyl cellulose, polyvinyl acetate and polyvinyl alcohol, and suitable catalysts are acids, e.g. tartaric acid, and substances developing an acid reaction in the presence of formaldehyde, e.g. ammonium chloride or mono ammonium phosphate. In Example (5) methanol is used as an additional solvent for gelatine.ALSO:In a process for filling, stiffening, glazing or delustering fibrous materials by impregnation with an aqueous preparation containing a hydrophyllic colloid, a urea-formaldehyde condensation product and a catalyst for the latter, a urea-formaldehyde condensation product of a degree of condensation in which it has a low water tolerance is used (i.e. it is sufficiently hydrophobic to be thrown out of solution before, on dilution, the concentration falls to 10%), and an aqueous solution thereof is diluted with water in the presence of the colloid so that it is thrown out of solution into intimate association with the colloid. The necessity for baking the materials after impregnation is thus avoided. The mol. ratio of urea to formaldehyde in the condensation product is preferably between 1 : 1,5 and 1 : 2, and the ratio of resin to colloid is preferably within the range of 1 : 4 and 4 : 1, although in the case of highly viscous colloids it may be as high as 15 : 1. Specified hydrophyllic colloids are starch, gelatine, carboxymethyl cellulose, polyvinyl acetate and polyvinyl alcohol, and suitable catalysts are acids, e.g. tartaric acid, and substances developing an acid reaction in the presence of formaldehyde, e.g. ammonium salts. The aqueous preparation is preferably applied to the fibrous materials by padding followed by drying on heated drying cylinders or passage between heated embossing rollers or glazing bowls to impart mechanical effects. Specified fibres are cotton, viscose rayon and cellulose derivatives, e.g. cellulose acetate.
