A filament for an oral care implement has a longitudinal axis and a multi-edged cross-sectional area extending in a plane substantially perpendicular to the longitudinal axis, the multi-edged cross-sectional area having at least 18 projections and at least 18 grooves, the projections and grooves being arranged in an alternating manner. Each projection has a peak, and each groove has a bottom formed by neighboring and converging projections. Each peak has a height, the height being defined as a perpendicular distance measured from the peak of the projection to a tangent between to neighboring bottoms. Each groove has a depth, the depth being defined as a perpendicular distance measured from the bottom of the groove to a tangent between two neighboring peaks. A ratio of the peak height to the depth of the groove is from about 1 to about 2, preferably about 1.5.
A filament (20) for an oral care implement (10), the filament (20) having a longitudinal axis (22) and a multi-edged cross-sectional area (24) extending in a plane substantially perpendicular to the longitudinal axis (22), the multi-edged cross-sectional area (24) having at least 18 projections (26) and at least 18 grooves (28), the projections (26) and grooves (28) being arranged in an alternating manner, each projection (26) having a peak (30), and each groove (28) having a bottom (32) formed by neighboring and converging projections (26), each peak (30) has a height (50), the height (50) being defined as a perpendicular distance measured from the peak (30) of the projection (26) to a tangent (52) between to neighboring bottoms (32), and
A filament (20) according to any of the preceding claims, wherein a distance (48) measured between one peak (30) of a projection (26) to a neighboring peak (30) of another projection (26) is within a range from about 0.01 mm to about 0.05 mm.
