Abstract
This invention relates to a flame-resistant spun staple yarns and fabrics and garments comprising these yarns and methods of making the same. The yarns have 25 to 90 parts by weight of a polymeric staple fiber containing a structure derived from a monomer selected from the group consisting of 4,4′diaminodiphenyl sulfone, 3,3′diaminodiphenyl sulfone, and mixtures thereof; and 10 to 75 parts by weight of a textile staple fiber having limiting oxygen index of 21 or greater, based on 100 parts by weight of the polymeric fiber and the textile fiber in the yarn.
