Abstract: Lightweight, flexible protective fabrics for protecting a person, animal or other object from hot burning materials, hot high heat capacity and/or hot corrosive materials, such as hot molten metal, hot oily liquids (e.g., heating oil), hot gels, hot solids, hot sparks, and hot acids. The lightweight protective fabrics can be used to protect a person, animal or other object from hot molten metals, such as liquid metal zinc heated to a temperature of about 950° F. (510° C.) or greater, hot molten aluminum heated to a temperature of about 1150° F. (620° C.) or greater, burning phosphorus at temperature of about 1550° F. (843° C.) or greater, hot solid iron having a temperature of about 500° F. (260° C.) or greater, hot heating oil having a temperature of about 500° F. (260° C.) or greater, and hot hydrochloric acid having a temperature of about 300° F. (150° C.) or greater.

Abstract: Methods of protecting a person, animal or other object from hot high heat capacity and/or hot corrosive materials, such as hot molten metal, hot oily liquids (e.g., heating oil), hot gels, hot solids, hot sparks, and hot acids. The methods include protecting a person, animal or other object from hot molten metals, such as liquid metal zinc heated to a temperature of about 950° F. (510° C.) or greater, hot molten aluminum heated to a temperature of about 1150° F. (620° C.) or greater, burning phosphorus at temperature of about 1550° F. (843° C.) or greater, hot solid iron having a temperature of about 500° F. (260° C.) or greater, hot heating oil having a temperature of about 500° F. (260° C.) or greater, and hot hydrochloric acid having a temperature of about 300° F. (150° C.) or greater. The ability to protect a wearer from heat from hot high heat capacity materials and/or hot corrosive materials is quite different from simply shedding liquids, even flammable liquids, such as gasoline is unexpected.

Abstract: Fire retardant and heat resistant yarns and fabrics include a fabric or yarn comprised of oxidized polyacrylonitrile at least partially coated or encapsulated by a strengthening polymer material that helps the fabric or yarn shed liquids, gels, sparks, and molten metals. The polymer material includes one or more types of cured silicone polymer resin. A fluorochemical may be at least partially impregnated into the fabric or yarn prior to applying the strengthening polymer material in order to further enhance the shedding properties of the yarns or fabric. In one embodiment, the silicone polymer resin only coats or encapsulates the yarn, but does not form a continuous coating over the whole fabric, so that the treated fabric is still able to breath through pores and spaces between individual yarn strands that make up the fabric. The polymer material increases the strength, abrasion resistance, durability and shedding capability of the fire retardant heat resistant yarn or fabric.

Abstract: Fire retardant and heat resistant yarns and fabrics include an inner core comprised of oxidized polyacrylonitrile encapsulated by an outer shell comprised of a liquid-resistant and strengthening polymer material. The liquid-resistant and strengthening polymer material includes one or more types of cured silicone polymer resin. A fluorchemical may be at least partially impregnated into the inner core prior to applying the liquid-resistant and strengthening polymer material in order to further enhance the liquid shedding properties of the yarns or fabric. Because the silicone polymer resin only encapsulates the yarn, but does not form a continuous coating over the whole fabric, the treated fabric is still able to breath through pores and spaces between individual yarn strands that make up the fabric. The liquid-resistant and strengthening polymer material increases the strength, abrasion resistance, durability and liquid and gel shedding capability of the fire retardant heat resistant yarn or fabric.
