PCT No. PCT/EP96/03690 Sec. 371 Date Jun. 11, 1998 Sec. 102(e) Date Jun. 11, 1998 PCT Filed Aug. 22, 1996 PCT Pub. No. WO97/09906 PCT Pub. Date Mar. 20, 1997A 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. A brush, particularly a toothbrush or interdental cleaner, with a plurality of bristles, optionally combined into bundles and in which at least certain bristles have the aforementioned structure, is also disclosed. |
