Claims13
A fiber blend spun into a yarn structure for use in assembling protective clothing to provide multifunctional protection including flame resistance to a wearer, the yarn structure consisting of, by weight:
- about 44% meta-aramid fiber;
- about 5% para-aramid fiber;
- about 50% wool fiber;
- and
- about 1% electrostatic dissipative fiber;
- wherein each of the fibers and the yarn structure is absent any flame retardant treatment, wherein the yarn structure has a flame resistance that meets requirements for U.S. military applications, foreign military, firefighting, industrial work wear, and first responder apparel and wherein the yarn structure is formed into a fabric that after a three second exposure to a flame, the fabric demonstrates about a 12% total body burn in accordance with ASTM F-1930.
