Abstract (en)

A tuft for an oral care implement comprises a plurality of filaments. Each filament has a longitudinal axis and a substantially cross-shaped cross-sectional area extending in a plane substantially perpendicular to the longitudinal axis. The cross-shaped cross-sectional area has four projections and four channels, and the projections and channels are arranged in an alternating manner. Each channel has a concave curvature formed by neighboring and converging projections. The concave curvature has a radius, and the radius of the concave curvature of the channel is within a range from about 0.025 mm to about 0.10 mm. The tuft has a packing factor within a range from about 40% to about 55%.
