In brushware comprising a bristle support and bristles connected thereto, at least part of the bristles are combined into bristle groups, wherein the separation between the bristles is smaller than the separation between the geometrical centers of neighboring bristle groups. Such brushware is characterized in that the separation between the geometrical center of at least one bristle group and the geometrical center of at least one neighboring bristle group is substantially equal to or larger than the product between the average number of bristles in the two bristle groups and the average diameter of these bristles. This design and arrangement permits the working ends of the bristles of these bristle groups to be linearly arranged in the brushing direction, irrespective of their mounting surface on the bristle support, to penetrate into narrow gaps and depressions. |
