<p>Treating fireproofing textiles, comprises (a) preparing a first bath comprising a composition having two components A and B, (b) impregnating the textile to be treated in the bath obtained in the step (a), (c) heat-drying the impregnated textile, during the polymerization reaction of the urea of component B and the phosphorous compound of component A, (d) stabilizing and neutralizing by an oxidation reaction of the polymer obtained in the step (c) in a second bath, (e) washing in water and drying the treated textile, and (f) recovering the fireproofed textile. Treating fireproofing textiles, comprises (a) preparing a first bath comprising a composition having two components A and B, where the component A comprises at least one phosphorous compound and the component B comprises urea and at least one pH buffer, (b) impregnating the textile to be treated in the bath obtained in the step (a) of which the pH is 4-6, (c) heat-drying the impregnated textile, during the polymerization reaction of the urea of component B and the phosphorous compound of component A, (d) stabilizing and neutralizing by an oxidation reaction of the polymer obtained in the step (c) in a second bath, (e) washing in water and drying the treated textile, and (f) recovering the fireproofed textile, where the second bath comprises, in addition to at least one oxidizing compound, a mixture of diacetone acrylamide and at least one organic acid dihydrazide.</p> |
