FIELD: consumer goods industry.
SUBSTANCE: invention relates to light industry, in particular, to production of fire-resistant textile material, and can be used for manufacture of clothes and filtering means of individual protection. Fire-retardant textile material contains non-woven material on the basis of polyacrylonitrile and polyvinylidene fluoride with applied on it fire-proof coating successively applied on base of fluoroplastic dispersion layers and alcohol solution of 3-aminopropyl-triethoxysilane with further drying.
EFFECT: due to successive impregnation with silicon- and fluorine-containing compounds coating improves fire-proof properties of non-woven material.
