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 20 to 50 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 50 to 80 parts by weight of a rigid-rod staple fiber, based on 100 parts by weight of the polymeric fiber and the rigid-rod fiber in the yarn.
