Patent

CA 2693331

The invention concerns a fiber, obtainable by spinning a copolymer from the polymerization solution, derived from 4,4'diaminodiphenyl sulfone amine monomer and a plurality of acid monomers, wherein the plurality of acid monomers has 55 to 85 mole percent of the monomer containing a para-oriented aromatic group and 15 to 45 mole percent of the monomer containing a meta-oriented aromatic group; and yarns, fabrics and garments comprising this fiber, and methods of making the same. This fiber has use in heat-resistant protective apparel fabrics and garments.

L'invention concerne une fibre pouvant être obtenue par filage d'un copolymère à partir de la solution de polymérisation, dérivée d'un monomère 4,4'-diaminodiphénylsulfone amine et d'une pluralité de monomères acides, la pluralité de monomères acides comportant 55 à 85 pour cent en mole du monomère contenant un groupe aromatique orienté para et 15 à 45 pour cent en mole du monomère incluant cette fibre ainsi que des procédés de fabrication de ceux-ci. Cette fibre est utilisée dans des tissus et vêtements pour habits protecteurs résistant à la chaleur.
