FLAME RESISTANT SPUN STAPLE YARNS MADE FROM BLENDS OF FIBERS DERIVED FROM DIAMINO DIPHENYL SULFONE, LOW THERMAL SHRINKAGE FIBERS, FLAME RESISTANT FIBERS, AND ANTITSTATIC 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 andgarments comprising these yarns andmethods of making the same. The yarns have at least 25 parts by weight of apolymeric staple fiber containing a polymer orcopolymer derived from a monomer selected from the group consisting of4,4'diaminodiphenyl sulfone, 3,3'diaminodiphenyl sulfone, andmixtures thereof; 2 to 15 parts by weight of a fiber having low thermalshrinkage; 1 to 5 parts by weight of an antistatic fiber; andthe remainder being flame resistant fibers having a limiting oxygen index of21 or greater, based on 100 total parts by weight of thepolymeric fiber, the low thermal shrinkage fiber, the antistatic fiber, andthe flame resistant fibers in the yarn.
