Abstract

L'invention concerne des monofilaments à extrémités fendues. Les monofilaments peuvent être utilisés pour former des poils de brosse à dents dont les pointes sont assouplies et effilées. Chaque monofilament présente une pluralité de lignes internes de fusion et au moins quatre parties évidées occupant entre 5 et 20 % de la superficie de section des monofilaments. Chaque monofilament présente de préférence un diamètre compris entre 0,0025 et 0,012 pouces et une configuration à six ou huit parties évidées. Les monofilaments sont fabriqués par extrusion d'une pluralité de flux thermoplastiques polymériques, par rotation d'une pluralité de lames tranchantes au-dessus de 1000 tours/mn et par la mise en contact d'une pluralité de lames tranchantes avec les extrémités des flux thermoplastiques polymériques de façon à former des extrémités fendues.
