Abstract (en)

[origin: WO2012082434A1] Described is a flame-resistant spun yarn having: about 50 to about 95 parts by weight of a sulfonated polyoxadiazole based staple fiber comprising repeat units of Formula (I) and one or both of Formula (II) and (I la): wherein M is a cation; and about 5 to about 50 parts by weight of a textile staple fiber having limiting oxygen index of 21 or greater and a tenacity of about 4 grams per denier or greater, based on the total amount of the polymeric fiber and the textile fiber in the yarn.
