COMPOSITION FOR TEXTILE FABRIC FIRE PROTECTION AND METHOD FOR PRODUCING LOW-COMBUSTIBLE TEXTILE FABRICS Russian patent published in 2011 - IPC A62D1/00 C09K21/10 

FIELD: medicine, fire-fighting means.

SUBSTANCE: invention refers to fire-protective compositions and fireproof fabrics with low smoke generation and toxicity of combustion products. The composition for fibre-blend textile fabric fire protection contains nitrilomethylene phosphonic acid, ammonium bicarbonate as a nitrogen-bearing compound in the ratio 1.1:1.0 with acid and zinc acetate in amount 20-40 g/l or 0.25-0.4 weight fractions. A method for producing a textile fabric of the low combustibility, smoke generation ability and low toxicity of combustion products, involves impregnation of the textile fabric with said composition followed by wringing thereof, drying and heat treatment at 140-160°C. The technique described above may be used for treating the textile fabrics from natural and synthetic fibres.

EFFECT: group of inventions provides low smoke generation abilities of the fabrics and reduced toxic gas flow after their thermal decomposition.
