Abstract
(EN)
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.
(FR)
L'invention concerne un filé de fibres ignifuges qui présente : d'environ 50 à environ 95 parties en poids de fibres courtes à base d'un polyoxadiazole sulfoné comportant les unités répétitives de la formule (I) et d'au moins une des formules (II) et (IIa) : où M représente un cation; et d'environ 5 à environ 50 parties en poids de fibres courtes textiles ayant un indice d'oxygène limitant d'au moins 21 et une ténacité d'au moins environ 4 grammes par denier, sur la base de la quantité totale de la fibre polymère et de la fibre textile dans le fil.
