Definitions
- the invention relates to a bristle for a toothbrush, in particular for a electric toothbrush, which is made of plastic and several, together connected filaments.
- Such a bristle is known from German utility model 19 97 717. There is described a toothbrush that has a variety of bristles has, with each bristle several filaments approximately parallel to each other arranged and thermally welded together. In this way the cleaning area formed by the free ends of the bristles is increased and thus increases the cleaning effect of the toothbrush. On the other hand arise however, voids between the filaments caused by bacteria or other Germs can be colonized.
- DE-PS 906444 describes a method for producing artificial bristles known, which consist of a plurality of individual filaments. These single filaments are glued together after exiting the spinnerets, the gluing is interrupted at intervals. After making the bond the bristle becomes individual bristles in the area of the non-glued areas cut, with the single bristle spliced at the tip.
- This method is quite complex, since on the one hand the filaments are admitted with an adhesive Need to become. On the other hand, it turns out to be problematic Continuously interrupt gluing at specified intervals.
- a brush with radially outward is on a hub attached bristles known.
- Each of the bristles points in the middle a stiff soul with at least one fiber made of vibration damping Material is glued and wrapped helically so that only part the surface of the soul is surrounded by the fiber.
- JP, A, 03289906 shows a bristle for a toothbrush made of several interconnected filaments that are wound or braided.
- the object of the invention is to provide a bristle for a toothbrush mentioned type in such a way that a high cleaning effect is guaranteed cavities should be avoided.
- the for the Tooth cleaning effective surface of the toothbrush increases and thereby the Improved teeth cleaning.
- winding or braiding achieves that the surface of the bristles is structured, which is important when cleaning teeth can be used effectively. Both are particularly important beneficial in removing plaque from the tooth surface.
- a free end is provided. This fanning out can be done by a Breaking the connection points of the individual filaments at the free end the bristle can be reached.
- the free end of the Bristle individual thin tips, the number and diameter of the number and the diameter of the filaments of the bristle.

- the cross-sectional area with amorphous structure is about 10% up to 50%, in particular 20% to 30% of the total cross-sectional area of the Bristle.
- the remaining cross-sectional area accordingly has an im essential crystalline structure.
- the filaments are wound bristle essentially without torsional stress or braided and chemically together by exposure to solvents welded. After the winding or braiding process, a connection is made of filaments due to chemical agents. This way it becomes permanent Connection between the individual filaments achieved, the mechanical Properties of the filaments are essentially retained. It arises a filament composite that forms the bristle. Furthermore, by dissolving closing the filaments in a solvent from those still present Cavities guaranteed safely.
- the fixation mentioned also represents a simple one and well controllable way, the coiled or braided Process filaments and combine them into bristles.
- the filaments during chemical welding with tensile stress from about 6MPa to 20MPa, preferably 13MPa. This is ensured that the wound or torsional stress-free braided filament during chemical welding with sufficient radially inward force are against each other, this radially inward force by means of the tensile stress acting on the filaments is produced.
