Abstract: A vest made of a light weight spacer fabric material that is permeable to air circulation and voluminous enough to have a significant thermal insulative value is provided. The spacer fabric material is also non-absorbent, hard wearing, compression resistant, readily cleanable, as well as non-burning and non-dripping when exposed to flames. The spacer fabric material includes fabric faces of an open mesh construction connected by a system of monofilament threads for promoting fabric rigidity.

Abstract: An improved knit fabric system for protecting against electrical arch hazards and promoting garment visibility is provided. The inventive knit fabric is either a solid fabric substrate or of a mesh construction that absorbs the thermal energy of an electric arc and, especially for the mesh construction, absorbs thermal energy or heat flux to prevent garment combustion. The solid or mesh version of the inventive knit fabric incorporates conductive fibers for draining away and thereby dissipating accumulated electrical charges. Such conductive fibers are incorporated into the fabric of the invention, by either being knitted into the fabric as it is formed or by the process of yarn spinning.

Abstract: A fire retardant fabric for safety garments useful for dangerous activities, e.g. firemen, policemen, armed forces, etc., is knit from a first yarn system of fire retardant modacrylic fibers, a second yarn system of flexible fibers and, optionally a third yarn system of aramid fire retardant fibers. One of the yarn systems also includes fibers formed of a conductive material, such as silver.

Abstract: An improved fabric for orthopedic devices is provided, being a knitted fabric produced on either a warp or weft knit system and utilizing a filament yarn selected from nylon and polyester as well as spandex. The fabric enhances freedom of movement while stimulating blood flow and muscle tone. The fabric has an elasticity that enables closure of orthopedic and other devices by placing the hook component of a Velcro (®) strip at any convenient point rather than aligning it with the loop component of the Velcro (®). The fabric is more convenient, faster and easier for many incapacitated persons, enhancing wearing comfort. Its mesh structure makes it more porous, which enhances the air circulation and the moisture management in creating a cooling effect on the wearer's skin and ready evaporation of perspiration, while still providing therapeutic warmth without heat buildup.
