Abstract

The present invention is directed to a textile fabric. This fabric is particularly well suited for use as the outer shell fabric of a firefighter's garment. The fabric is a woven or knitted fabric of spun yarns and multi-filament yarns. The spun yarn includes a first staple being a polymer selected from the group consisting of aramid, PBI or PBO or melamine formaldehyde, and a second staple being an aramid polymer. The multi-filament yarn includes an aramid filament.

Claims (19)

1. A firefighter garment comprising: an outer shell fabric including a woven material of spun yarns including first staple being a polymer selected from the group consisting of PBI, and/or PBO, and a second staple of an aramid polymer, and multi-filament yarns including a para-aramid filament, and a weight ratio of spun yarn to multi-filament yarn ranges from 85:15 to 92:8.

2. The garment of claim 1 wherein the woven fabric weight ranging from 6 to 8 OSY.

3. The garment of claim 1 wherein the woven fabric has a weave selected from the group consisting plain, twill, rip stop, or oxford.

4. The garment of claim 1 wherein the spun yarn ranges from 32/2 to 16/2 c.c.

5. The garment of claim 1 wherein the multi-filament yarn ranges from 200 to 1500 denier.

6. A firefighter garment comprising: an outer shell fabric including a woven material of spun yarn, said spun yarn being a blend of staple, a first staple being made of a polymer selected from the group consisting of PBI, PBO, or combinations thereof and a second staple being made of an aramid, and a multi-filament yarn including para-aramid filaments, said multi-filament yarns being inserted into said woven material, in both the warp and the weft, at a multi-filament yarn to spun yarn ratio of 1:5 to 1:20.

7. The garment of claim 6 wherein said spun yarn being a blend of PBI and aramid staple.

8. The garment of claim 6 wherein said spun yarn being a blend of PBO and aramid staple.

9. The garment of claim 6 wherein said spun yarn being a blend of PBI, PBO, and aramid staple.

10. A firefighter garment comprising: an outer shell fabric including a woven material of spun yarns including first staple being a polymer selected from the group consisting of aramid, PBI, and/or PBO, and a second staple of an aramid polymer; multi-filament yarns including a para-aramid filament; and a weight ratio of spun yarn to multi-filament yarn ranges from 85:15 to 92:8.

11. A firefighter garment comprising: an outer shell fabric including a woven material of spun yarn, said spun yarn being a blend of staple, a first staple being made of a polymer selected from the group consisting of aramid, PBI, PBO, or combinations thereof and a second staple being made of an aramid, and a multi-filament yarn including para-aramid filaments, said multi-filament yarns being inserted into said woven material, in both the warp and the weft, at a multi-filament yarn to spun yarn ratio of 1:5 to 1:20.

12. A firefighter garment comprising: an outer shell fabric including a woven material of spun yarn, said spun yarn being a blend of staple, a first staple being made of an aramid polymer selected from the group consisting of meta-aramid, para-aramid, or combinations thereof and a second staple being made of an aramid polymer selected from the group consisting of meta-aramid, para-aramid, or combinations thereof, and a multi-filament yarn including para-aramid filaments, said multi-filament yarns being inserted into said woven material, in both the warp and the weft, at a multi-filament yarn to spun yarn ratio of 1:5 to 1:20, said woven fabric having a greater trap tear when compared to a fabric of equivalent weight without said filament and a greater tabor abrasion when compared to the fabric of equivalent weight without said filament.

13. A firefighter garment comprising: an outer shell fabric including a woven material of spun yarns including first staple being an aramid polymer selected from the group consisting of meta-aramid, para-aramid, and combinations thereof, and a second staple of an aramid polymer; multi-filament yarns including a para-aramid filament; and a weight ratio of spun yarn to multi-filament yarn ranges from 85:15 to 92:8, said woven fabric having a greater trap tear when compared to a fabric of equivalent weight without said filament and a greater tabor abrasion when compared to the fabric of equivalent weight without said filament.

14. A textile fabric comprising: a woven fabric of spun yarns and multi-filament yarns, the spun yarns being in the warp and the weft, the multi-filament yarns being in the warp and the weft, the spun yarn being a blend of staple selected from the group aramid, PBI, PBO, and combinations thereof, the multi-filament yarn being a para-aramid multi-filament yarn, and a weight ratio of spun yarn to multi-filament yarn ranging from 85:15 to 92:8.

15. The fabric of claim 14 wherein said spun yarn having a cotton count in the range of 32/2 to 16/2.

16. The fabric of claim 14 wherein said multi-filament yarns being inserted into said woven material, in both the warp and the weft, at a multi-filament yarn to spun yarn ratio of 1:5 to 1:20.

17. A firefighter garment comprising an outer shell fabric according to claim 14 .

18. A firefighter garment comprising: an outer shell fabric including a woven material of spun yarns including first staple being a polymer selected from the group consisting of PBI, and/or PBO, and a second staple of an aramid polymer, and multi-filament yarns including a filament having a tenacity of at least 22 grams per denier, and a weight ratio of spun yarn to multi-filament yarn ranges from 85:15 to 92:8.

19. A textile fabric comprising: a woven fabric of spun yarns and multi-filament yarns, the spun yarns being in the warp and the weft, the multi-filament yarns being in the warp and the weft, the spun yarn being a blend of staple selected from the group aramid, PBI, PBO, and combinations thereof, the multi-filament yarn comprising a filament having a tenacity of at least 22 grams per denier, and a weight ratio of spun yarn to multi-filament yarn ranging from 85:15 to 92:8.
