The preferred facing material includes, in a first embodiment, a facing layer having an areal weight of about 300 grams/M2, and an air permeability rating of no greater than about 300 CFM/ft2 (FG 436-910 test method).

Abstract: A clothing material structure of fiber cloth containing PAN series activated carbon includes an air-permeable textile as a support layer and fiber cloth containing PAN series activated carbon as an adsorption layer. The support layer and the adsorption layer are bonded together to form the clothing material suitable for the hunter clothing and the protective clothing by way of bonding or needle punching. Accordingly, when the wearer's body heat and body odor try to pass through the clothing made from the material, the body heat may smoothly pass through the adsorption layer while the body odor is blocked and filtered out by the activated carbon fiber. Thus, the requirements of hunter clothing may be satisfied. Furthermore, the odors or toxins trying to pass through the adsorption layer may be filtered out, and the requirements of the chemically protective clothing and hunter clothing may be satisfied.

Abstract: A material to reduce the effects of trauma received from the impact of a projectile. One embodiment is a needle-punched, non-woven material including at least one type of ballistic fibers selected and oriented to provide a cushioning effect and maintain a high compressive restitution constant. A percentage of the fibers are oriented with at least their ends lying approximately perpendicular to the fabric plane and/or oriented to lie in a waveform generally along or parallel to the fabric plane. This enables the ends of the fibers lying perpendicular to the fabric plane to cushion the impact from the projectile by dissipating energy through compressional resistance, and the fibers along the fabric plane to reduce energy through dispersal along fiber lines, thereby reducing the trauma resulting from an impact.
