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.
Claims19
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.
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.
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.
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.
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.
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.
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.
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.
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.
