Flame Resistant Fabric and Garments Made Therefrom

摘要

Protective garments include a flame resistant fabric that is strong and yet has a soft hand. The fabric is made from a combination of filament yarns and spun yarns. The filament yarns and spun yarns are woven together such that the filament yarns are separated by from about 2 to about 5 spun yarns in both the warp direction and the fill direction. The spun yarns may contain polybenzimidazole fibers in combination with other fibers, such as aramid fibers. The filament yarns may comprise para-aramid fibers. In one embodiment, the filament yarns may have a size larger than the spun yarns.

1. A flame resistant garment comprising:
a fabric shaped to cover at least a portion of a wearer's body, the fabric comprising filament yarns combined with spun yarns, the filament yarns comprised of inherently flame resistant filaments, the spun yarns including yarns comprised of polybenzimidazole or poly-p-phenylenebenzobisoxazole fibers in combination with aramid fibers, and wherein the fabric includes a warp direction and a fill direction and wherein the filament yarns and the spun yarns are positioned in the warp direction in a ratio of from greater than 1:1 to 1:4 and wherein the filament yarns and the spun yarns are also positioned in the fill direction in a ratio of from greater than 1:1 to 1:4.
