FIELD: fire-resistant materials. ^ SUBSTANCE: invention relates to fabricating fire-resistant material suitable to make filter-type individual respiratory defense systems. Material contains textile sheet with, applied thereon, emulsion polyvinylchloride-based fire-retardant composition in the form of discrete layer. Material additionally has, on its reverse side, (i) a sorption layer constituted mainly by carbon-containing material with, applied on its both sides or on the side being in front of facing layer, discrete coating based on polyvinylchloride containing fire retardants, and (ii) reverse layer containing woven or unwoven material made from cotton, viscose, synthetic fibers or mixtures thereof. ^ EFFECT: acquired high fire-resistant and heat-resistant properties with high air permeability and thereby defense against poisons preserved. ^ 2 cl, 2 dwg, 1 tbl, 2 ex |
