(First invention)
In the paper brush hair manufacturing method according to the first aspect of the present invention, an adhesive is applied to a paper sheet, and then the paper sheet to which the adhesive is applied is rolled into a rod-like body. The rod-shaped body is surrounded by a cover ring. There is at least one rod-like body. The cover ring may be at least single. In the paper brush hair manufacturing method, powdery or granular abrasive grains are sprinkled on the fibers of the paper sheet and then embedded between the paper fibers. The embedding of the abrasive grains into the paper sheet can be achieved by pressing or the like after expanding the paper fiber with moisture or the like. In the paper sheet containing the abrasive grains, at least one rounded rod-like body becomes a paper brush hair. Further, after the paper sheet is coated with an adhesive, the powdery or granular abrasive grains are dispersed. The paper sheet is rolled up so that at least one rod-like body becomes a bristle. The rod-shaped body and the cover ring are basically manufactured by the same means.

  The paper sheet can be made of Japanese paper such as kenaf or straw. A paper sheet made of Japanese paper is made of thin fibers such as whiskers, has a light and shaded thickness, and has a unique flexibility at the tip, for example, wipes a relatively soft surface such as a liquid crystal display screen. A paper brush can be produced. In addition, the paper sheet is not limited to Japanese paper, and any paper can be used. Depending on the type of paper used, a unique softness of the brush bristles occurs.

  In addition, wood pulp that is usually used has a slightly lower strength than Japanese paper. Furthermore, western paper, waste paper, milk cartons, cardboard, etc. have unique softness different from Japanese paper, and can obtain unique flexibility different from synthetic resin brush hair. There are a large number of types of paper, and in combination with the types and sizes of adhesives and / or abrasive grains, when using as paper brush bristles, it is possible to select one that suits the purpose and purpose.

  The abrasive grains are at least one of silicon carbide, alumina, zirconia, diamond, emery, cerium oxide, metal abrasive grains, and the like, and a predetermined amount is adhered by an adhesive. The amount of the abrasive grains and the adhesive can be arbitrarily selected depending on the intended use of the paper brush and the object to be wiped with the paper brush. Furthermore, the place where the abrasive grains and the adhesive are put can be arbitrarily selected according to the purpose of use of the paper brush and the object to be wiped with the paper brush, as described above.

  The adhesive is not particularly limited, but a natural paste, synthetic resin, or rubber-based adhesive dissolved in water, alcohol, inorganic, or organic resin-based solvent is preferable. A brush material having a desired hardness can be obtained by adjusting the concentration of the solvent according to the purpose. The adhesive referred to in the present invention is for adhering a paper material and therefore includes water. Even if it is described that the adhesive of the present invention is applied to paper, in addition to application, the adhesive is applied to the paper material by a wide range of means such as spraying and dipping.

(Second invention)
The paper bristle manufacturing method in the second invention includes a step of applying an adhesive and / or abrasive grains to a paper sheet, a step of rolling the paper sheet to produce a rod-like body, and a rod-like body obtained by rounding the paper sheet A step of twisting the twisted rod-shaped body, a step of gathering one or a plurality of the twisted rod-shaped bodies into paper brush hairs, and at least one of the rod-shaped bodies And at least a step of performing a covering surrounding the periphery.

  The twisted rods, in addition to scoring them, cover the surroundings to provide the unique softness that arises from the type of paper, the frictional forces that arise from the twisting and twisting of the paper, and the It has a unique strength by covering it, and it becomes a bristle brush made of paper that is firm, lightweight, and flexible. At least one or a plurality of the twisted and twisted rod-shaped bodies are assembled into a paper brush hair. The highly flexible paper brush bristles are implanted in the implantation member. Further, the waist strength of the paper brush bristles is unique due to the type of paper, twisting and twisting, which is not made of synthetic resin, etc., and can be easily changed by appropriately adjusting the length. . Examples of the implant member include a deck, a cylinder, and a channel.

  In the paper brush hair production method, the paper sheet coated with the adhesive and / or abrasive grains is rolled, then twisted and further rolled, so that the softness of the tip, frictional force, elasticity, The strength of the waist is unique to paper, and not only has unique characteristics as an abrasive brush, but also has high weather resistance against water and high strength. Paper brush bristles produced by the production method described above include, for example, a screen of a liquid crystal display device, a glass member (particularly lens surface polishing), a paper type suitable for polishing the surface of a ceramic member, twisting, and the like. It combines the unique softness, strength, and flexibility resulting from sag.

  In addition, the twisted and twisted paper brush bristle material has not only a gap in addition to the unique softness of the paper in the twisted and twisted portions, but also adhesive and / or abrasive grains on the cover ring. Therefore, the vibration of the polishing surface can be absorbed, and a unique effect is exhibited for polishing a relatively hard member from a soft member on the surface.

  In addition to polishing the surface of the member, the paper brush bristles can be used for ordinary hair brushes, interdental brushes, and the like. In addition to paper brush hair, the hair brush and interdental brush can be made lightly by making the handle part a paper member, and can discharge toxic gas during incineration. There is no effect.

  In the paper brush hair manufacturing method, a thin paper sheet is rolled into a rod-like body and twisted after being twisted. The squeezed rod-like body is knitted into a net shape to form a paper brush hair in a net state. The net-like paper brush bristles are bundled so that the tip portion or the side portion becomes a paper brush. The weaving may be in various ways such as a knot net (main net, cocoon net), a knotless net (no knot net, Russell net), a woven net, or a twisted net.

  These net-like paper brush bristles have a brush surface at the tip or side when bound. After twisting the paper, the tip of the brushed bristle made of the crushed paper is strong but soft. In addition, various types of polished surfaces can be produced from the bound side portions by mesh. Furthermore, the paper brush produced from the paper-like paper brush bristles can be produced with various deformations such as a loose mesh crossing part and a hard crossing part hard to move, A paper brush suitable for the purpose of use can be produced. The tip portion or side surface portion of the brush made of the paper net state can have a unique friction surface resulting from paper type, twisting and twisting, which is not found in the synthetic resin brush.

  In the paper brush hair manufacturing method, an adhesive is soaked in the vicinity of the tip of the paper brush hair, or abrasive grains are attached. The paper brush bristles can be formed into a desired shape using a mold or the like, if necessary. For example, the paper brush bristles can be sharpened from the vicinity of the tip toward the tip, or the tip can be made spherical. The shape of the tip of the paper brush bristles can be formed into an arbitrary shape by changing the shape of the mold as desired in addition to the above.

  The tip of the paper brush bristles can be adjusted for hardness as well as shape by adjusting the type or concentration of the adhesive. The paper brush hair soaked with the adhesive can have a unique softness resulting from the type and concentration of adhesive, the type of paper, twisting, and twisting. In addition, the paper brush bristles can be made of a net-like covering, but can also be covered with a paper sheet containing an adhesive and / or abrasive grains.
