Abstract:
The invention concerns a flame-resistant spun staple yarns and fabrics and garments comprising these yarns and methods of making the same. The yarns have 50 to 75 parts by weight of a polymeric staple fiber containing a polymer or copolymer derived from a monomer selected from the group consisting of 4,4′diaminodiphenyl sulfone, 3,3′diaminodiphenyl sulfone, and mixtures thereof; 2 to 15 parts by weight of a fiber having low thermal shrinkage; 1 to 5 parts by weight of an antistatic fiber; and the remainder being flame resistant fibers having a limiting oxygen index of 21 or greater, based on 100 total parts by weight of the polymeric fiber, the low thermal shrinkage fiber, the antistatic fiber, and the flame resistant fibers in the yarn.
