DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surface treatment function for removing dust and other contaminants adhering to resin films, electronic equipment parts, optical materials, packaging materials, painted surfaces of automobiles, etc., and static electricity removal. The present invention relates to a brush material that provides a brush having both functions.

[0002]

2. Description of the Related Art Conventionally, various types of resin films, electronic device parts such as IC boards, optical materials such as lenses and glass plates, and packaging materials have been subjected to dust and the like using various brushes in the manufacturing process. Kimono must be removed.
There are various reasons why dust is not allowed. For example, a resin film differs depending on its use. For example, when a pressure-sensitive adhesive sheet is produced using a resin film as a base material, when dust enters the pressure-sensitive adhesive, bubbles, floating, or peeling may occur. Also, when printing is performed on the surface of the resin film, the dust causes poor appearance and the like. In addition, dust causes poor contact and the like in electronic device parts, causes poor light transmission in optical materials, and is undesirable in packaging materials for hygiene and beauty.

On the other hand, dust and the like adhere to the surface of automobiles and the like together with water scale and oil, and these must be cleaned and removed with a brush or the like using water or a surfactant as in a car washing apparatus.

As a brush for removing dust and other contaminants as described above, a filament made of a natural fiber or a synthetic resin fiber has conventionally been used, and a bundle thereof or a braided bundle of these filaments has been used. Was used as a brush material.

[0005]

However, the conventional brush as described above is not suitable for surface treatment of a material to be treated.
There is a problem that static electricity is generated by friction. Further, even if it does not generate static electricity itself, at least there is no effect of removing static electricity on the surface of the agent to be treated. This static electricity ignites the flammable organic solvent and causes a fire, or adsorbs dust and dirt floating in the air, spoiling cleaning (especially cleaning performed to remove dust). Sometimes it was. In addition, a dust removal brush provided in the middle of a traveling mechanism such as a synthetic resin film may generate static electricity on the film surface, which may cause the film to become entangled with the brush or the feed roll, thereby causing a traveling failure. Was.

[0006] Therefore, there has been a demand for a brush capable of performing a surface treatment for removing dust and other contaminants while removing static electricity, and a material therefor.

DISCLOSURE OF THE INVENTION The present invention has been proposed in view of the above, and is a carbon fiber having a thickness of 0.1 to 0.5 mm, wherein a carbon layer is formed on an outer peripheral portion of a polyamide core wire. Alternatively, a first fiber which is a carbon fiber having a thickness of 0.1 to 0.5 mm obtained by mixing 30 to 60% by weight of carbon powder in polyamide, polypropylene or polyvinyl chloride, and a second fiber which is an animal natural fiber And a third fiber which is a synthetic resin fiber having a thickness of 0.1 to 0.5 mm, which is a polyamide, polypropylene or polyvinyl chloride and is a composite fiber, wherein the first fiber and The second fiber is 5 to 9 with respect to the whole.
The present invention relates to a brush material characterized by being 0% by weight.

[0008]

The following examples of the present invention will be described. As the first fiber in the present invention, a fiber having a thickness of 0.1 to 0.5 mm in which a carbon layer is formed by continuously coating carbon on the outer peripheral portion of a polyamide core wire, or polyamide, polypropylene or poly 30 for vinyl chloride
0.1 to 0.5 mixed with carbon powder of 60% by weight
Millimeter-thick fibers can be used. The first fibers described above mainly contribute to the effect of removing static electricity.

The second fiber in the present invention is a natural fiber. For example, animal fibers mainly from pigs, horses, goats and the like can be used. In the case of animal fibers, the second fibers described above have high abrasion resistance because they are protein fibers,
Moreover, since it is generally flexible, dust can be removed without damaging the agent to be treated. In addition, when used as a cleaning brush to be used together with water or a surfactant, the strength is low, so the effect of removing contaminants adhering to the surface of the processing object is low. Is better.

The third fiber in the present invention is a synthetic resin fiber. For example, the third fiber is made of polyamide (nylon), polypropylene, polyvinyl chloride or the like.
0.5 millimeter thick fibers can be used. The above-mentioned third fiber contributes to dust removal or a cleaning effect similarly to the above-mentioned second fiber. In particular, since the third fiber has higher strength than the second fiber, it has a high effect of removing contaminants adhering to the surface of the object to be treated.

Further, the above-mentioned third fiber has an effect of giving a firmness (elasticity) to the whole brush material. That is, most of the second fibers are too soft to maintain the brush shape, but by using the third fibers in combination, the shape retention of the manufactured brush can be improved. In addition, the above-mentioned effect also has the first fiber which is the same material (synthetic resin fiber). Is declining.

As described above, the mixing ratio of the composite fiber is such that the first fiber and the second fiber are 5
~ 90% by weight. The above mixing ratio may be appropriately set depending on the material (surface hardness) of the material to be treated, the use (purpose), and the like.

For example, when the material to be treated having a relatively high surface hardness is to be dust-removed, or when it is used for cleaning together with water and a surfactant, the third fiber is set at a high ratio. on the other hand,
When removing dust from materials with relatively low surface hardness,
Set the second fiber to a high percentage.

The composite fibers obtained by mixing the first to third fibers can be manufactured into various brushes according to the shape of the material to be processed. The manufacturing method is not particularly limited, and a brush may be formed by appropriately converging or the like by a known method.

The brush material of the present invention has not only a surface treatment function such as dust removal but also a static electricity removal function. Therefore, the brushes prepared in various sizes and shapes by concentrating the brush material of the present invention can be used for surface treatment such as dust removal and cleaning, and can leave an adverse effect of static electricity after the treatment. Absent.

[0016]

As described above, the brush material of the present invention can provide a brush having both a surface treatment function such as dust removal and a static electricity removing function. Therefore, the brush obtained by bundling the brush material of the present invention removes dust and other contaminants adhering to resin films, electronic device parts, optical materials, packaging materials, painted surfaces of automobiles, and the like. In addition to the above-mentioned surface treatment, static electricity is removed, and the above-mentioned fire and other various problems are not caused.

Further, since the brush material of the present invention is constructed without using special raw materials, it can be easily put into practical use.
