Abstract (en)
[origin: WO2014007948A2] Described is a flame-resistant spun yarn having: about 50 to about 95 parts by weight of a sulfonated naphthalene polyoxadiazole based staple fiber comprising repeat units of Formula (I) and one or both of Formula (II) and (Ila) wherein Q is H or SO3M, and M is one or more cations; and about 5 to about 50 parts by weight of a textile staple fiber having limiting oxygen index of 24 or greater and a tenacity of about 2 grams per denier or greater, based on the total amount of the polymeric fiber and the textile fiber in the yarn.
