Abstract

Des fibres creuses se différencient par leur vide partiellement rempli d'une protubérance d'un matériau polymère de caractérisation. Ce matériau peut être identique ou différent de celui du reste de la fibre. La protubérance est obtenue par un réglage approprié des capillaires en cours de filage, c.-à-d. au cours de l'extrusion, en vue de former la fibre.
