Solidified structures made of textile materials are produced by 1 to 250% by weight, preferably 10 to 100% by weight, of a melamine-formaldehyde precondensate with a molar ratio of melamine: formaldehyde = 1 to a textile material, based on solid resin : (0.8 to 1.26), preferably 1: (1.01 to 1.2), in liquid or solid form, optionally in the presence of 0.1 to 5% by weight, based on solid resin, of a latent Harder is applied and the material, optionally after an intermediate sintering or intermediate drying, is pressed at an overpressure of 1 to 200 bar and temperatures of 130 to 220 ° C and, if necessary, is simultaneously three-dimensionally deformed. |
