Description

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 attached to resin films, electronic equipment parts, optical materials, packaging materials, and painted surfaces of automobiles, 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 resin films, electronic equipment parts such as IC boards, optical system materials such as lenses and glass plates, packaging materials, etc. are dusted with various brushes in the manufacturing process. Kimono must be removed.
There are reasons why dust is not allowed, but for example, resin films differ depending on their applications. As an 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 or floating or peeling may occur. Also, when printing is performed on the surface of the resin film, dust causes a defective appearance and the like. Further, dust causes contact failure in electronic device parts and causes light transmission failure in optical system materials, and is not preferable in hygiene or aesthetics in packaging materials.

On the other hand, dust and the like adhere to the surface of automobiles and the like along with water stains and oil, which must be removed by cleaning with a brush or the like using water or a surfactant as in a car washing device.

As a brush for removing dust and other contaminants as described above, conventionally, filaments of natural fibers or synthetic resin fibers have been used, and these filaments have been bundled, or these filaments have been braided and bundled. I used it as a material for brushes.

[0005]

However, in the conventional brush as described above, when the surface of the material to be treated is treated,
There was a problem that static electricity was generated by friction. Further, even if it itself did not generate static electricity, there was at least no effect of removing static electricity on the surface of the agent to be treated. And this static electricity ignites flammable organic solvent and causes a fire, and it adsorbs dust and dust floating in the air, ruining cleaning (especially cleaning performed for the purpose of removing dust). Sometimes In addition, the dust removal brush provided in the middle of the traveling mechanism such as a synthetic resin film may cause traveling failure due to the film being entangled with the brush or the feed roll by generating static electricity on the film surface. It was

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

SUMMARY OF THE INVENTION The present invention has been proposed in view of the above, and is a first fiber which is a carbon fiber, a second fiber which is a natural fiber, and a third fiber which is a synthetic resin fiber. A composite fiber in which fibers are mixed, the first fiber and the second fiber
The present invention relates to a material for a brush, characterized in that the amount of the fibers is 5 to 90% by weight based on the whole.

[0008]

EXAMPLES Examples of the present invention will be described below. The first fiber in the present invention is, for example, a fiber having a thickness of 0.1 to 0.5 mm in which carbon is continuously applied to the outer peripheral portion of a polyamide core wire to form a carbon layer, or polyamide, polypropylene, or 0.1 to 30% by weight of carbon powder mixed with polyvinyl chloride
Fibers with a thickness of 0.5 millimeters can be used. The above-mentioned first fiber mainly contributes to the static electricity removing effect.

The second fiber in the present invention is a natural fiber, but mainly animal fiber such as pig, horse and goat can be used. In the case of animal fiber, the above-mentioned second fiber is a protein fiber and therefore has high abrasion resistance,
Moreover, since it is generally flexible, it is possible to remove dust without damaging the agent to be treated. In addition, when used as a cleaning brush for use with water or a surfactant, the strength is low, so the effect of removing contaminants adhering to the surface of the object to be treated is low, but the water retention of water (cleaning water) is low. Is excellent.

The third fiber in the present invention is a synthetic resin fiber, and is made of, for example, polyamide (nylon), polypropylene or polyvinyl chloride.
Fibers with a thickness of 0.5 millimeters can be used. The above-mentioned third fiber contributes to the dust removal or cleaning effect similarly to the above-mentioned second fiber. In particular, the strength of the second fiber is higher than that of the second fiber, and therefore the effect of removing contaminants adhering to the surface of the object to be treated is high.

Furthermore, the above-mentioned third fiber also has the effect of imparting elasticity (elasticity) to the entire brush material. That is, many of the above-mentioned second fibers are too soft to hold the brush shape, but by using this third fiber in combination, it is possible to improve the shape holding property of the manufactured brush. In addition, although the above-mentioned effect also has the first fiber which is the same material (synthetic resin fiber), these have a lower elasticity (elasticity) than the third fiber because of the amount of carbon powder mixed. It is falling.

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

For example, when the material to be treated having a relatively high surface hardness is to be removed by dust or used for cleaning with water and a surfactant, the third fiber is set to a high ratio. on the other hand,
If you want to remove dust from a material with a relatively low surface hardness,
Set the second fiber to a high percentage.

The composite fiber obtained by mixing the first to third fibers can be made into various brushes depending on the shape of the material to be treated. The manufacturing method is not particularly limited, and may be appropriately focused to form a brush by a known method.

The brush material of the present invention has a surface treatment function such as dust removal and a static electricity removal function. Therefore, the brush produced 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 the negative influence of static electricity can be left 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 removal function. Therefore, the brush obtained by bundling the brush material of the present invention removes dust and other contaminants attached to resin films, electronic device parts, optical system materials, packaging materials, painted surfaces of automobiles, etc. The surface treatment can be performed, and the static electricity is removed so that the above-mentioned fire and other various problems are not caused.

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