Abstract
Embodiments of the invention relate to flame resistant fabrics formed of a combination of filament and long staple yarns that exhibit excellent physical and thermal properties at relatively light weights.
Claims20
A flame resistant fabric comprising:
- (a) a plurality of long staple yarns comprising a plurality of long staple fibers comprising flame resistant material;
- and
- (b) a plurality of filament yarns comprising flame resistant material, wherein the flame resistant fabric is devoid of short staple yarns.
A woven flame resistant fabric having a warp direction and a fill direction, the fabric comprising:
- (a) a plurality of flame resistant long staple yarns extending in both the warp and fill directions, wherein at least some of the plurality of long staple yarns comprise a fiber blend comprising a plurality of first long staple fibers comprising a first type of material and a plurality of second long staple fibers comprising a second type of material different from the first type of material;
- and
- (b) a plurality of flame resistant filament yarns interwoven with the plurality of long staple yarns in both the warp and fill directions.
A woven flame resistant fabric having a warp direction and a fill direction, the fabric comprising:
- (a) flame resistant first long staple yarns extending in both the warp and fill directions, wherein each first long staple yarn comprises a fiber blend comprising a plurality of first long staple fibers comprising a first type of material and a plurality of second long staple fibers comprising a second type of material different from the first type of material;
- (b) flame resistant second long staple yarns extending in both the warp and fill directions, wherein each second long staple yarn is formed of a single type of material;
- and
- (c) flame resistant filament yarns interwoven with the first and second long staple yarns in both the warp and fill directions, wherein:
- each end of the first long staple yarns comprises at least two first long staple yarns plied together;
- each end of the second long staple yarns comprises at least two second long staple yarns plied together;
- and
- more than three but less than eight first long staple yarn ends and second long staple yarn ends are collectively provided between adjacent filament yarn ends in at least one of the warp direction or the fill direction.
