Abstract

A woven flame-resistant fabric for garments, the warp and fill yarns being made up of at least about 30 wt. % inherently flame-resistant fibers. The fabric is woven from a plurality of warp yarn groups consecutively arranged across the width direction in a recurring pattern, each warp yarn group consisting of a plurality of adjacent consecutively arranged warp yarns. At least one warp yarn in each warp yarn group is woven with the fill yarns in a plain (1/1) weave and at least one warp yarn in each warp yarn group is woven in one or more non-plain weaves each selected from the group consisting of 1/2, 2/1, 2/2, 1/3, and 3/1. Approximately half of the warp yarns in the fabric are woven in a plain (1/1) weave and the remaining warp yarns in the fabric are woven in the one or more non-plain weaves, in an alternating fashion.

First claim

What is claimed is:

1. A woven flame-resistant garment fabric, the fabric comprising warp yarns that extend in a longitudinal or warp direction and fill yarns that extend in a width direction of the fabric, the warp and fill yarns comprising at least about 30 wt. % inherently flame-resistant fibers, the fabric being a single-layer fabric woven from a plurality of warp yarn groups consecutively arranged across the width direction in a recurring pattern, each warp yarn group consisting of a plurality of adjacent consecutively arranged warp yarns,
wherein at least one warp yarn in each warp yarn group is woven with the fill yarns in a plain (1/1) weave and at least one warp yarn in each warp yarn group is woven with the fill yarns in one or more non-plain weaves each selected from the group consisting of 1/2, 2/1, 2/2, 1/3, and 3/1, and
wherein approximately half of the warp yarns in the fabric are woven with the fill yarns in a plain (1/1) weave and the remaining warp yarns in the fabric are woven with the fill yarns in said one or more non-plain weaves, in an alternating fashion.

2. The woven flame-resistant garment fabric of claim 1 , wherein the maximum number of adjacent plain-woven warp yarns in the fabric is 2.

3. The woven flame-resistant garment fabric of claim 1 , wherein the fabric has both 1/2 woven warp yarns and 2/1 woven warp yarns.

4. The woven flame-resistant garment fabric of claim 1 , wherein each warp yarn group consists of 4 warp yarns.

5. The woven flame-resistant garment fabric of claim 4 , wherein the fabric is devoid of any multiple adjacent plain-woven warp yarns.

6. The woven flame-resistant garment fabric of claim 5 ,
wherein the warp yarn group consists of 2 plain-woven warp yarns alternating with 2 non-plain-woven warp yarns.

7. The woven flame-resistant garment fabric of claim 6 , wherein the warp yarn group consists of a plain-woven warp yarn, followed by a 1/2 woven warp yarn, followed by a plain-woven warp yarn, followed by a 2/1 woven warp yarn.

8. The woven flame-resistant garment fabric of claim 6 , wherein the fabric has a weight of about 4 oz/yd 2 to about 10 oz/yd 2 .

9. The woven flame-resistant garment fabric of claim 6 , wherein the fabric has a weight of about 4 oz/yd 2 to about 7.5 oz/yd 2 .

10. The woven flame-resistant garment fabric of claim 6 , wherein the fabric has a weight of about 4.5 oz/yd 2 to about 6 oz/yd 2 .

11. The woven flame-resistant garment fabric of claim 1 , wherein the fabric has an air permeability measured in accordance with ASTM D737 that is at least about 20% greater than that of a comparable plain-woven fabric constructed from the identical warp and fill yarns and having the same weight in oz/yd 2 .

12. The woven flame-resistant garment fabric of claim 1 , wherein the warp yarns are all identical to each other, and the fill yarns are all identical to each other.

13. The woven flame-resistant garment fabric of claim 12 ,
wherein the warp yarns are identical to the fill yarns.

14. The woven flame-resistant garment fabric of claim 13 , wherein the warp and fill yarns comprise about 30 wt. % to about 100 wt. % aramid fibers.

15. The woven flame-resistant garment fabric of claim 14 , wherein the warp and fill yarns comprise about 45 wt. % to about 100 wt. % aramid fibers.

16. A garment constructed from the woven flame-resistant garment fabric of claim 1 .

17. A woven flame-resistant garment fabric, the fabric comprising warp yarns that extend in a longitudinal or warp direction and fill yarns that extend in a width direction of the fabric, the warp and fill yarns comprising at least about 30 wt. % inherently flame-resistant fibers, the fabric being a single-layer fabric woven such that approximately half of the warp yarns are woven with the fill yarns in a plain (1/1) weave and the remaining warp yarns are woven with the fill yarns in one or more non-plain weaves each selected from the group consisting of 1/2, 2/1, 2/2, 1/3, and 3/1, in an alternating fashion, wherein the fabric has a weight of about 4 oz/yd 2 to about 7.5 oz/yd 2 , and wherein the fabric has an air permeability measured in accordance with ASTM B737 that is at least about 20% greater than that of a comparable plain-woven fabric constructed from the identical warp and fill yarns and of equal weight in oz/yd 2 .

18. The woven flame-resistant garment fabric of claim 17 , wherein the warp yarns are all identical to each other, and the fill yarns are all identical to each other.

19. The woven flame-resistant garment fabric of claim 18 ,
wherein the warp yarns are identical to the fill yarns.

20. The woven flame-resistant garment fabric of claim 19 , wherein the warp and fill yarns comprise about 30 wt. % to about 100 wt. % aramid fibers.

21. The woven flame-resistant garment fabric of claim 20 , wherein the warp and fill yarns comprise about 45 wt. % to about 100 wt. % aramid fibers.

22. The woven flame-resistant garment fabric of claim 17 , comprising about 90 to 95 wt. % meta-aramid fibers, about 2 to 8 wt. % para-aramid fibers, and about 1 to 3 wt. % anti-static fibers.

23. The woven flame-resistant garment fabric of claim 17 , comprising about 30 to 90 wt. % modacrylic fibers, about 5 to 65 wt. % aramid fibers, and about 0 to 5 wt. % anti-static fibers.

24. The woven flame-resistant garment fabric of claim 17 , comprising about 40 to 80 wt. % modacrylic fibers, about 15 to 55 wt. % aramid fibers, and about 1 to 4 wt. % anti-static fibers.

25. The woven flame-resistant garment fabric of claim 17 , comprising about 50 to 70 wt. % modacrylic fibers, about 25 to 45 wt. % aramid fibers, and about 2 to 3 wt. % anti-static fibers.
