Abstract
In one embodiment, a flame resistant fabric includes a plurality of flame resistant body yarns that form a body of the fabric, and a plurality of relatively tough yarns provided in discrete positions within the fabric body, the relatively tough yarns comprising a filament yarn that includes a filament composed of one of polyolefin, flame resistant polyester, polytetrafluoroethylene, polyetheretherketone, polyetherimide, polysulfar, polyimide, polyamide, polyimideamide, polybenzoxazole, polybenzimidazole, carbon, and glass.
Claims25
A flame resistant fabric, comprising:
- a plurality of flame resistant body yarns that form a body of the fabric, wherein each body yarn comprises a diameter;
- and
- a plurality of relatively tough yarns provided in discrete positions within the fabric body, wherein each relatively tough yarn comprises a diameter and wherein at least some relatively tough yarns each comprises a filament yarn that comprises a filament comprising at least one of a polyolefin, flame resistant polyester, polytetrafluoroethylene, polyetheretherketone, polyetherimide, polysulfar, polyimide, polyamide, polyimideamide, polybenzoxazole, polybenzimidazole, carbon, or glass;
- wherein the diameter of the relatively tough yarns is the same or smaller than the diameter of the body yarns so that the relatively tough yarns do not protrude beyond an outer surface of the fabric body.
