The present invention relates to a yarn having improved abrasion resistance and a fabric made from that yarn, as well as process for preparing the yarn and fabric. The yarn includes (a) aramid fibers and (b) up to 40 weight percent of fibers of synthetic polymers having a melting point between 200 and 300 degrees C, based upon the total weight of (a) and (b) only, the yarn or fabric including the yarn being heat treated at a temperature below the melting point of the fibers of component (b).

La présente invention concerne un fil présentant une résistance à l'abrasion améliorée, un tissu constitué par ce fil, ainsi qu'un procédé de préparation de ce fil et de ce tissu. Ledit fil comprend (a) des fibres aramides et (b) jusqu'à 40 % en poids de fibres de polymères synthétiques présentant un point de fusion compris entre 200 et 300 ·C, sur la base du poids total de (a) et (b) uniquement. Ce fil ou ce tissu est préparé par traitement thermique du fil à une température inférieure au point de fusion des fibres du composant (b).
