Resistance of Navy Shipboard Outerwear Garments and Fire-Resistant Fabrics to Extreme Heat

摘要

The heat protective capabilities of a variety of fabrics used in Navy Shipboard outerwear garments have been characterized in several ways. Fabric tensile strength retention during short-term exposure to bilateral radiant heat at fluxes to 0.8 cal/sq cm sec, time-to-ignition at bilateral radiant fluxes to 1.1 cal/sq cm/sec, and the level of heat transferred to an underlying surface as the result of unilateral radiation to 1.25 cal/sq cm/sec and flame exposure at 2.2 cal/sq cm/sec have all been measured. Thirty-six single-layer fabrics and fabric assemblies have been used in the investigation ranging in weight from 3 to 25 oz/sq yd. Fabric materials tested include cotton, wool, modacrylic, Nomex, Kevlar, PAN, corespan semi-carbon/Kevlar, coated fabrics and various blends.
