Abstract

La présente invention concerne un procédé de fabrication d'un voile non tissé et à constituants multiples qui comprend un mélange de divers types de filaments mis simultanément sous forme d'un voile unique. Ces filaments peuvent varier au niveau de leur composition polymère, de leurs charges en additifs, de la taille ou de la forme de leurs fibres, et/ou de leur degré de frisage. Cette invention concerne également un procédé de fabrication d'une structure non tissée à plusieurs couches, dans laquelle divers types de filaments constituant les différentes couches sont fabriqués simultanément.
