Flame resistant textile
A flame resistant textile containing a plurality of warp yarns in a warp direction of the textile interwoven with a plurality of weft yarns in the weft direction approximately perpendicular to the warp direction. The warp yarns contain inherent FR polyester yarns having between about 1500 and 3500 ppm of a phosphorous based FR chemistry and the weft yarns contain polyester yarns. the textile contains more weft yarns by weight than warp yarns and wherein the FR textile contain about 1500 ppm or less of the phosphorous based FR chemistry.

A flame resistant (FR) textile comprising a plurality of warp yarns in a warp direction of the FR textile interwoven with a plurality of weft yarns in the weft direction approximately perpendicular to the warp direction, wherein greater than 95% by number of the warp yarns are inherent FR polyester yarns having between about 1500 and 3500 ppm of a FR chemistry comprising phosphorous, wherein the weft yarns comprise polyester yarns, wherein the FR textile comprises more weft yarns by weight than warp yarns, and wherein the FR textile comprises about 1000 ppm or less of the FR chemistry.
2. The FR textile of claim 1 , wherein at least 90% by number of the polyester weft yarns comprise less than 100 ppm of the FR chemistry.
3. The FR textile of claim 1 , wherein the FR textile comprises at least about 51% by weight weft yarns.
4. The FR textile of claim 1 , wherein the FR textile passes at least one of the NFPA 701 v2015, California Title 19 fire test, and Canadian ULC 109 ed. 3 tests.
5. The FR textile of claim 1 , wherein the FR textile is wash durable for at least 30 washes defined as ASTM D5489 industrial laundry method and still passing NFPA 701 v2015.
6. The FR textile of claim 1 , further comprising a durable water repellent, fluorine-free, flame resistant treatment.
