CA 2233945

Fiberfill and/or multi-void fibers are identified and/or differentiated by one or more voids being partially filled with a differentiating characteristic that is a protuberance of characterizing polymer material. This material may be the same or different from that of the rest of the fiber. The protuberance is provided by appropriate adjustment of the spinning capillary, i.e., during extrusion to form the fiber.

Des fibres de rembourrage et/ou des fibres à plusieurs vides sont identifiées et/ou différenciées par au moins un vide partiellement rempli d'une protubérance de matériau polymère de caractérisation. Ce matériau peut être identique ou différent de celui composant le reste de la fibre. Cette protubérance est formée par un réglage approprié des capillaires en cours de filage, c.-à-d. au cours de l'extrusion, en vue de former la fibre.
