FIELD: fireproof textiles.
SUBSTANCE: invention relates to methods of chemically treating fibrous materials, in particular, imparting to textiles fireproof properties. Method comprises soaking textile in aqueous solution of polyacrylonitrile/phosphoric acid reaction product, wherein principal complexing moiety is α-aminoalkylidenediphosphonic compound, until content of the latter in textile achieves 50-73 wt %, after which textile is dried to its residual content 13-15%. Textile is then hardened with ammonia and held for 1 h. Hardened polymer is oxidized to convert trivalent phosphorus into pentavalent state and then washed and dried.
EFFECT: optimized technology of high-quality fireproof impregnation of materials.
