Abstract (en)
The present invention relates generally to bristles, in particular tooth-cleaning bristles comprising a surface structure with at least one surface recess such as dimples and pittings, and to a method for manufacturing such a bristle. Moreover, the present invention also relates to a toothbrush head including a plurality of tufts of such bristles. According to the present invention, the method for manufacturing the bristle is characterized in that a bristle body with at least a portion made of a material soluble by a corrosive agent is covered in part with a cover layer stable to said corrosive agent such that a surface portion of said bristle body substantially corresponding to said at least one surface recess is uncovered, and said bristle body is contacted with said corrosive agent for a limited time to create the surface recess in said uncovered surface portion. Correspondingly, a bristle according to the present invention is characterized in that its surface structure includes at least one etch pitting or etch recess in a bristle body made at least in part of a material soluble by a corrosive agent.
