FIELD: fire-resistant materials.

SUBSTANCE: invention relates to fabricating fire-resistant material suitable to make filter-type individual respiratory defense systems. Material represents textile sheet with, applied thereon, emulsion polyvinylchloride-based discrete coating with fire resistance-imparting materials. Coating contains 15-25 wt parts talc or chalk and 40-60 wt parts trichloroethyl phosphate per 100 wt parts polyvinylchloride. As textile sheet, textile made from blend of polyester fibers with cotton or linen fibers, or with blend of cotton or linen fibers with wool fibers used in following proportions, wt %: polyester fibers 40-60 (warp) and 20-40 (weft), cotton and linen fibers 40-60 (warp) and 60-80 (weft), wool fibers 15-20 (warp) and 10-15 (weft).

EFFECT: assured protection of material against open flame over prolonged period of time with high air permeability preserved.
