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

摘要

This invention relates to flame-resistant spun staple yarns and fabrics and garments comprising these yarns and methods of making the same. The yarns have 50 to 95 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 5 to 50 parts by weight of a polyoxadiazole fiber, based on the total amount of the polymeric fiber and the polyoxadiazole fiber in the yarn.
