This invention relates to flame-resistant spun staple yarns and fabrics and garments comprising these yarns and methods of making the same. The yarns have 50 to 95 parts by weight of a polymeric staple fiber containing a structure derived from a monomer selected from the group consisting of 4, 4 'diaminodiphenyl sulfone, 3, 3 'diaminodiphenyl sulfone, and mixtures thereof; and 5 to 50 parts by weight of a high modulus staple fiber having a tensile modulus of 200 grams per denier (180 grams per dtex) or greater, based on 100 parts by weight of the polymeric fiber and the high modulus fiber in the yarn.
L'invention concerne des fils courts filés résistant à la flamme, des tissus et des vêtements contenant ces fils et leurs procédés de fabrication. Les fils comportent 50 à 95 parties en poids d'une fibre courte polymère contenant une structure dérivée d'un monomère choisi dans le groupe incluant la 4,4'-diaminodiphénylsulfone, la 3,3'-diaminodiphénylsulfone et leurs mélanges, et 5 à 50 parties d'une fibre courte de module élevé dont le module de traction est égal ou supérieur à 200 grammes par denier (180 grammes par dtex) pour 100 parties en poids de la fibre polymère et de la fibre à module élevé présentes dans le fil.
