Abstract
An alumina-silica hydrate fiber for thermal protection in the most hazardous environments experienced by firefighters. The fiber has a combination of heat resistance at temperatures above 1,000° C. and an endothermic behavior when heated. Its endothermic condensation reaction releases up to 12% water upon heating, thereby contributing to the thermal insulating properties. The fibers are extremely soft to the touch and do not irritate the skin. They are also non-respirable in the deep lung, so they can be used safely without risk of inhalation. The fabric is sufficiently lightweight and flexible as well, allowing firefighters to move easily. These properties of alumina-silica hydrate fibers enable their use for apparel.
