FLAME RESISTANT SPUN STAPLE YARNS MADE FROM BLENDS OF FIBERS DERIVED FROM DIAMINO DIPHENYL SULFONE AND TEXTILE FIBERS AND FABRICS AND GARMENTS MADE THEREFROM AND METHODS FOR MAKING SAME

摘要

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.
