Abstract: A method for the manufacture of surface-structured bristle material from plastic by extruding a monofilament. Before or during extrusion a granular material is admixed with a thermally melted first plastics material forming the main component of the monofilament. The granular material comprises a second plastics material, which has a higher thermal strength than the first plastics material. The particle size of the granular material is such that the monofilament, during a subsequent stretching, is subject to a greater transverse contraction in cross-sections where there is little or no granular material than in cross-sections containing granular material. A disclosed bristle included a surface structure from a first plastics material forming the main component of the bristle and in which is embedded in a substantially completely covered manner a granular material of a second plastics material, the granular material forming a structuring on the bristle surface.
