Definitions

  • the invention relates to bristles with a surface structure and to a method for producing surface-structured bristle material from plastic by extruding a monofilament.
  • the invention relates to a brush, in particular a toothbrush or a
  • Interdental cleaner that is at least partially equipped with the surface-structured bristles.
  • Plastic bristles that are extruded are usually smooth on their surface due to the manufacturing process.
  • such bristles develop their brushing effect first and foremost through the free ends of the bristles, which are the soiled surface tear open and remove the dirt by scratching and scraping.
  • the bristles fold over and become effective with their outer surface. They slide more stroking and pushing over the surface with a gentler effect.
  • the bristles are curved so that they come into contact not only with their free bristle ends but also with their outer surface with the surface to be treated. For a long time there have therefore been considerations of using the outer surface of the bristles for surface treatment, by structuring or profiling them.
  • the large abrasive particles protruding from the surface also bring about a high level of abrasiveness.
  • the bristles are greatly weakened by the inclusion of the large abrasive particles, so that the bristles have insufficient strength.
  • EP-0 360 938 A1 proposes to embed a blowing agent in the bristle material and to achieve a surface roughness by foaming the blowing agent.
  • the chambers or bubbles that form in the entire bristle strand lead to a substantial reduction in the bristle stiffness.
  • the bristle surface is uneven due to the torn bubbles and does not have a defined structure depth or topography, as is necessary for effective broaching.
  • the invention has for its object to provide a bristle or a bristle material which has a predetermined surface topography with predetermined or only low abrasiveness, but increased broaching effect. Furthermore, a method for the production of bristle material is to be created with which corresponding bristles can be produced in a simple manner.
  • thermoplastic material melted, the main component of the extruded monofilament 1st plastic material is mixed with a granulate made of a second plastic material before or during extrusion, which has a higher thermal Strength than the 1st plastic material. If thermoplastic material is used as the second plastic material, it has a higher melting point. If another plastic material is used alternatively, it must be ensured that this is not, or at least not liquefied earlier than the 1st plastic material.
  • the grain size of the granules is such that the monofilament during subsequent stretching in cross sections in which little or no granules are arranged is subject to a greater reduction in cross section or cross contraction than in cross sections with a large amount of granules.
  • the granulate does not serve as an abrasive particle, but only as a shaped or resistance body in order to locally hinder the transverse contraction.
  • the first plastic material which can be polyamide, polyester, polyolefin or the like in a known manner, is heated in an extruder device and thereby made flowable. Then, during or before extrusion, the granulate from the second plastic material is mixed in an amount of preferably 5% to 30% of the total weight of the bristle material.
  • the dimensions of the granules and their shape depend on the desired surface structure. The dimensions can fluctuate, but should not be chosen too small. In a preferred embodiment of the invention it is provided that the size of a granulate is between 10% and 50% of the diameter of the bristle material.
  • the second plastic material of the granulate has a higher thermal strength or a higher melting point than the oil forming the main component.
  • Has plastic material can be achieved that it does not melt or at most surface melts due to the heat of the first plastic material, so that the granules during extrusion as inherent inclusions in the flowable 1st plastic material are included.
  • the granulate also consists of plastic.
  • Deburring removes these sharp edges.
  • Deburring can be done thermally and / or mechanically. During thermal deburring, the granulate is melted on the surface so that the sharp edges run. Alternatively, it is possible to process the granules on the surface in drums before adding them to the 1st plastic material and thereby remove the edges.
  • the diameter is not reduced uniformly over the length, but the granules hinder the transverse contraction, so that a smaller cross-sectional reduction occurs in the area of a granule than in areas in which no granules are arranged.
  • the stretching thus leads to a surface structure of the monofilament.
  • the still flowable monofil with surface structure is then cooled in a known manner, whereby solidification is achieved.
  • the monofilament is then preferably subjected to a further stretching, which leads to a stretching to a multiple length and in particular to a further reduction in diameter.
  • the longitudinally oriented molecules of the 1st plastic material are not destroyed.
  • the monofilament or the bristle material can be stabilized in the usual way.
  • the abrasiveness of the second plastic material of the granulate is at most as high as that of the first plastic material, the abrasiveness of the bristle material is reliably prevented from being dependent on whether and to what extent granules on the Shell surface of the monofilament are arranged or come into effect. Even if the bristle flank or lateral surface wears off over the course of time and the granules should thereby tangle the lateral surface, the bristle has at most the same Abrasiveness like the main component 1. plastic material.
  • the granulate is embedded in the 1st plastic material and is essentially completely covered by it. This is achieved in that the granulate is wetted by the 1st plastic material in the extruder in such a way that it is predominantly covered by the plastic material when it emerges through the nozzle.
  • the monofilament thus has an outer surface which is essentially completely formed by the first plastic material.
  • the surface topography caused by the different cross-contractions in some areas is dependent on the shape of the granules and is based on them.
  • the granules can be spherical, cuboid or prism-shaped or contain a mixture of grains of different shapes.
  • the granulate does not melt during the extrusion process, so that the grains form an inherently stable, dimensionally stable inclusion in the first plastic material.
  • deburring can be achieved by the surface melting.
  • material combinations made of thermoplastic are preferably used, which weld well together.
  • nylon 6.12 for the first plastic material with granules made of polyphenylene sulfide.
  • the melting point difference between nylon 6.12 (218 ° C.) and polyphenylene sulfide (260 ° C.) has proven to be particularly advantageous.
  • Both the 1st plastic material and the 2nd plastic material of the granulate can be filled with fillers or unfilled.
  • the surface structuring is best visible when relatively little granulate is added to the 1st plastic material.
  • the abrasiveness decreases due to the small number of surface elevations.
  • the abrasion rate can be increased again by adding fillers to the first plastic material. In this way, a slightly abrasively filled bristle with a good surface structure can be achieved.
  • the granulate may be useful for the granulate to consist of a material that is harder than the first plastic material. In this case, the formation of the surface structure is advantageously supported and sustained. Alternatively, however, it is also possible for the granulate to consist of a material which is softer than the first plastic material. This creates a more resilient surface structure, as is particularly useful in devices for treating sensitive areas, for example the gums or the interdental spaces. To this end it is possible that the granules consist of a rubber-like material.
  • the first plastic material is made transparent or translucent.
  • the user can perceive the covered granulate, which preferably has a different color than the first plastic material, through the first plastic material.
  • these can be embedded in different colors in the transparent or translucent 1st plastic material.
  • the above-mentioned object is achieved in that the bristle consists of a first plastic material forming the main component, in which granules of a second plastic material are embedded in a substantially completely covered manner, the Granules form a structure on the surface of the bristle.
  • the abrasiveness of the second plastic material of the granulate corresponds at most to that of the first plastic material.
  • a monofilament as used for example in some interdental cleaners, can also have the features and advantages mentioned.
  • the bristles or the monofilament can have any cross-sectional shape and in particular be round, oval, triangular, square, star-shaped, etc.
  • the invention relates to a brush, in particular a toothbrush or an interdental cleaner, with a multiplicity of bristles which are optionally combined into bundles, at least some of the bristles being designed according to the invention.
  • the bristles according to the invention can also be combined with bristles of a different configuration and processed together.
  • Interdental cleaners are also known which consist of only one monofilament. The invention is also intended to include such interdental cleaners in which the monofilament is designed according to the invention.
  • the invention can also be used with brushes to achieve improved color retention, with hair brushes for good cleaning and degreasing ability, with massage brushes with better rubbing effect, with hand and machine-operated brooms for increased dirt absorption, with pads for polishing and Use grinding with a higher degree of efficiency through surface topography as well as with woven, braided or in any other way mats, cleaning devices, applicators, polishing or grinding devices made from bristles or monofilaments.
  • the invention can be implemented in a filter that has an enlarged monofilament surface due to the structuring.
  • FIG. 1 a longitudinal section of a monofilament after extrusion
  • Figure 2 the monofilament after pre-stretching
  • Figure 3 the monofilament after further stretching.
  • a monofilament 10 immediately after it leaves the extruder nozzle has a substantially uniform cross-section over the length with a smooth outer surface 13, with a plurality of granules in a 1st plastic material 11 forming the main component of the monofilament 10 12 are embedded from a second plastic material in an irregular arrangement.
  • the granules 12 are partly spherical and partly cuboid.
  • the first plastic material 11 is flowable, while the granules 12 form solid, stable inclusions.
  • the monofilament is pre-stretched (see arrows in FIG.
  • FIG. 3 The structuring of the lateral surface 13 of the monofilament 10 which is thereby strengthened is shown in FIG. 3. It can be seen that the surface topography that forms depends on the shape of the granule. When spherical granules are used, substantially softer topography forms are formed than when using, for example, cuboid granules.
