CA 2192474

The invention relates to a filter for brewed beverages, especially a coffee filter, and a process for producing such a filter, in which a fibrous material has pores with an average pore width (d) of at least about 0.1 mm measured at a fiber density of about 50% of the original fiber density of the material. The average pore width (d) is preferably in a range from 0.1 mm to 0.7 mm approximately and more preferably in a range from 0.1 mm to 0.4 mm approximately. The material is preferably paper. The pores are also preferably made by piercing with needles or by subjecting the fibrous material to water jets, providing an irregular pore edge.

L'invention concerne un filtre pour boissons infusées, notamment un filtre à café, et un procédé de fabrication correspondant. Le filtre est réalisé dans un matériau avec fibres présentant des pores d'une largeur moyenne (d) d'au moins 0,1 mm environ pour une densité de fibres correspondant à environ 50 % de la densité de fibres initiale. La largeur moyenne des pores (d) est, de préférence, comprise dans une plage d'environ 0,1 mm à 0,7 mm et, plus particulièrement, de 0,1 à 0,4 mm. Le matériau est, de préférence, en papier. Afin d'obtenir des pores à bordure émoussée, il est de loin préférable de les réaliser au moyen d'aiguilles ou de jets d'eau pulvérisés à travers les fibres du matériau.
