  However, the conventional bristle material 1 described in Patent Document 1 has a problem in that the production cost is significantly increased because the manufacturing process becomes extremely complicated.

  Further, the conventional bristle material 3 described in Patent Document 2 has a problem that the monofilament has a corrugated shape, so that the fluff is weak and the cleaning performance is inferior.

  Moreover, although the hair material 6 described in Patent Document 3 has excellent dirt scraping performance due to the concave portions 6a and convex portions 6b formed on the surface, there is no core material inside the convex portions 6b. When the brush bristle material 6 was strongly pressed against the surface to be cleaned, there was a problem that the hair was easily broken.

  Moreover, since the bristle material described in patent document 4 has many fine recessed parts formed in the surface of each bristle material, there existed a subject that a bristle became weak and it became easy to break. In addition, there is a problem that the liquid once retained in the recess is not easily exchanged with the liquid outside the recess, and the liquid remains in the recess. In addition, there is a problem that it is necessary to improve the frictional force of the bristle material in order to efficiently scrape off the dirt adhered to the surface to be cleaned.

  SUMMARY OF THE INVENTION The present invention solves the above-described conventional problems, and an object of the present invention is to provide a low-priced brush excellent in dirt scraping performance, liquid holding performance such as paint and cleaning liquid, and durability.

  In order to solve the conventional problem, the brush of the present invention has a hair material made of a synthetic resin monofilament, has a plurality of large diameter portions in the fiber axis direction, and the synthetic resin monofilament and the large diameter portion. The core material is made of different materials, and it has a large diameter part and a small diameter part that is inevitably formed between them, so that it can scrape dirt and retain liquids such as paint and cleaning liquid. As well as improving, the core material of the material different from the synthetic resin monofilament is arranged in the large diameter part, so even if the hair material is strongly pressed against the surface to be cleaned, it is difficult to break and provides a brush with excellent durability I can do it.

  Moreover, the manufacturing method of the hair material used for the brush of this invention mixes a core material with the said synthetic resin, when melt-spinning the synthetic resin for synthetic resin monofilaments of any one of 1st-3rd invention.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

Example 1
FIG. 1 is a front view of a brush in the first embodiment of the present invention.

  In FIG. 1, the brush 21 has a handle portion 22 and a brush portion 23 connected by a joint portion 24. The brush portion 23 is made of the synthetic resin monofilament hair material 11 and is formed by being implanted in the joint portion 24. The brush 21 is used for cleaning, cleaning, liquid application, and the like, and the hair material used for the brush 21 of the present invention has the following characteristics.

  FIG. 2 is a cross-sectional view of the bristle material according to the first embodiment of the present invention.

  In FIG. 2, the hair material 11 is made of a polyolefin resin such as polyethylene, polypropylene, or polystyrene, a polyamide resin such as nylon 6, nylon 66, nylon 610, or nylon 612, polyethylene terephthalate, polybutylene terephthalate, polytrimethylene terephthalate, or the like. It is made of a polyester resin, an acrylic resin, a urethane resin, and the like, and includes a synthetic resin monofilament 13 having a plurality of large diameter portions 12 in the fiber axis direction and a core material 14 disposed in the large diameter portion 12.

  The core material 14 has a melting point from an inorganic material such as aluminum oxide, silicon carbide, boron carbide, iron oxide, chromium oxide, diamond, talc, kaolin, diatomaceous earth, silica, calcium carbonate, or a synthetic resin used for the synthetic resin monofilament 13. High synthetic resin should be used. As the synthetic resin having a high melting point, for example, granular or powdery fluororesin, silicone resin, and the like are preferable.

  Kaolin is a naturally occurring clay mineral mainly composed of aluminum silicate, and talc is an ore mainly composed of magnesium silicate.

  FIG. 3 is a schematic view showing a manufacturing method of the hair material 11. The synthetic resin pellets 13 a for the synthetic resin monofilament 13 and the granular core material 14 having a predetermined size are mixed well and then put into a material hopper 16. Then, melt spinning is performed at a temperature at which the synthetic resin pellets 13a are melted. At this time, as shown in FIG. 2B, the thickness of the synthetic resin monofilament 13 is substantially uniform, and the granular core material 14 that has not melted due to the high melting temperature is diffused in its original form. .

  Next, before the synthetic resin monofilament 13 is cured, if it is stretched using a predetermined jig, the portion where the core material 14 is located becomes the large diameter portion 12, as shown in FIG. Between the adjacent large diameter portions 12, the synthetic resin monofilament 13 extends to form the small diameter portion 15, and the bristle material 11 is completed.

  Since the bristle material 11 in the present embodiment is configured as described above, when it is used for the washing brush 21, the surface of the plurality of large diameter portions 12 is scraped off, or the surface is made dirty. Since it can be struck, the dirt scraping performance is greatly improved. In addition, since the liquid such as the cleaning liquid is held on the outer peripheral surface of the small diameter portion 15 formed between the two large diameter portions 12 adjacent to each other, the liquid holding performance is also improved. In particular, when a large number of bristle materials 11 are densely packed, the large diameter portions 12 are densely packed, so that the liquid holding performance is significantly improved.

  Furthermore, since the core material 14 is arranged in the large diameter portion 12, it is difficult to break even if the bristle material 11 is strongly pressed against the surface to be cleaned, and the brush 21 having excellent durability can be provided.

  Further, when the synthetic resin monofilament 13 is melt-spun by using an inorganic material or a synthetic resin having a higher melting point than the synthetic resin used for the synthetic resin monofilament 13 as the material of the core material 14, Even if the core material 4 is mixed in advance in the synthetic resin, the core material 14 that is not easily melted remains in the spun synthetic resin monofilament 13 as it is, and the hair material 11 of this embodiment is easily formed. Therefore, the hair material 11 can be produced in one line and production cost can be greatly reduced.

  If an inorganic material is used as the material of the core material 14, the grinding force is improved when the brush 21 is used in a form in which the core material 14 is exposed. It is effective for removal. In addition, when a synthetic resin is used as the material of the core member 14, the surface to be cleaned is not damaged and the dirt can be reliably removed.

  In addition, by using aluminum oxide, silicon carbide, boron carbide, iron oxide, chromium oxide, diamond, talc, kaolin, diatomaceous earth, silica stone, or calcium carbonate as an inorganic substance, it has excellent grinding power and is applied to the edges of products and parts. It is possible to provide a brush 21 that is extremely effective in removing the formed burrs. In particular, iron oxide and chromium oxide have high polishing power.

  As described above, the brush according to the present invention is excellent in dirt removal performance, cleaning performance, paint application performance, durability, and the like, and can be widely applied to various applications.
