Abstract
This invention is related to a protective fabric resistant to molten metals, comprising 10 to 40 percent by weight meta-aramid fiber, 30 to 50 percent by weight wool fiber, and at least 20 percent by weight flame-retardant viscose fiber. Such fabrics typically have a total weight in the range of 200 to 450 grams per square meter and preferably have a total weight in the range of 200 to 260 grams per square meter.
