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 first long staple yarns formed of a first fiber composition comprising a plurality of first long staple fibers having a length of greater than 2 inches up to about 40 inches, the first long staple fibers comprising a first flame resistant material;
- (b) a plurality of second long staple yarns formed of a second fiber composition comprising a plurality of second long staple fibers having a length of greater than 2 inches up to about 40 inches, the second long staple fibers comprising a second flame resistant material different from the first flame resistant material, wherein the second fiber composition is different from the first fiber composition;
- and
- (c) a plurality of flame resistant filament yarns, wherein the flame resistant fabric is devoid of short staple fibers having a length of 2 inches or less.
1 more element
A woven flame resistant fabric having a warp direction and a fill direction, the fabric comprising:
- (a) a plurality of first flame resistant long staple yarns comprising long staple fibers having a length of greater than 2 inches up to about 40 inches, the plurality of first flame resistant long staple yarns extending in both the warp and fill directions, wherein the plurality of first flame resistant long staple yarns are formed of a fiber blend comprising a first plurality of the long staple fibers of a first flame resistant material and a second plurality of the long staple fibers of a second flame resistant material different from the first flame resistant material;
- (b) a plurality of second flame resistant long staple yarns extending in both the warp and fill directions and comprising only a third flame resistant material, wherein the third flame resistant material is different from at least one of the first flame resistant material or the second flame resistant material;
- and
- (c) a plurality of flame resistant filament yarns interwoven with the plurality of first flame resistant long staple yarns and the plurality of second flame resistant 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 is formed of a fiber blend comprising a plurality of first long staple fibers having a length of greater than 2 inches up to about 40 inches and of a first flame resistant material and a plurality of second long staple fibers having a length of greater than 2 inches up to about 40 inches and of a second flame resistant material different from the first flame resistant material;
- (b) flame resistant second long staple yarns extending in both the warp and fill directions, wherein each second long staple yarn is formed entirely of a third flame resistant material, wherein the third flame resistant material is different from a least one of the first flame resistant material or the second flame resistant 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.
