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

摘要

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 25 to 80 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; and 20 to 75 parts by weight of a modacrylic fiber, based on 100 parts by weight of the polymeric fiber and the modacrylic fiber in the yarn.
