FIRE RESISTANT FABRIC Russian patent published in 2011 - IPC D03D15/12 

FIELD: textile, paper.

SUBSTANCE: fire-resistant fabric contains combined thread of warp and weft, which represents a two-component reinforced thread, where rod is represented by aramid complex thread of linear density 6.3-200 tex, and the second component in the form of braiding from yarn on the basis of oxydiazole with a ratio of turns 400-1000 twists per m and linear density of 10-200 at the following ratio of components (wt %): thread on the basis of aromatic copolyamide 10-50; yarn of fibre on the basis of oxydiazole 90-50. Fabric is made with warp fill ratio equal to weft fill ratio and making 1.1-1.3, aramid thread is thread on the basis of polyparaphenyleneterephthalamide, copolyparaphenyleneterephlal amide, polyparaphenylenebenzimidazoleterephlal amide, copolyparaphenylenebenzimidazoleterephthalamide, triple aromatic copolyamide.

EFFECT: possibility to develop fabric with high resistance to wear loads, resistance of dye relative to light effect, high fire and heat resistance properties.
