Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a brush material used for a cleaning brush.

[0002]

2. Description of the Related Art Conventionally, an automobile or the like is cleaned by rotating a roll brush in which relatively thick monofilaments are radially arranged and bringing the tip of the brush into contact with the object to be cleaned. It is desirable to remove only dirt from the brush material without damaging the object to be cleaned, but in reality, the thickness is such that the brush materials do not become entangled with each other, the length corresponds to the irregularities of the object to be cleaned, and the dirt is wiped off. It requires the necessary hardness, etc., and excessively rubs against the object to be cleaned.

In the case of an automatic car washing machine for automobiles, the outer diameter of the roll brush is about 1000 mm and the length of the brush material is 45 mm.
About 0 mm is required. If the length of the brush material is 450 mm, the thickness of the brush material needs to be about 1 to 2 mm. When such a thick monofilament is applied to the object to be cleaned by centrifugal force, considerable excessive friction occurs. Further, dust particles are attached to the object to be cleaned, and the attached dust particles may be separated and pinched between the brush and the painted surface of the car, or adhered to the brush to scratch the painted surface of the car. There is.

When the brush material is made into a multifilament and a considerably thin one is used, the contact is soft, but the brush materials are entangled with each other at the tip of the brush to form a large loop. There is a problem that the projections such as side mirrors are damaged.

In order to solve such a problem, the actual development of Sho 59
JP-A-59124 discloses a thin fibrous tip obtained by twisting a plurality of fiber bundles obtained by twisting a plurality of fine fibers made of a thermoplastic resin, and untwisting the twist at the tip of a twisted body obtained by hardening the twist with an adhesive. A car wash brush material having a portion is disclosed. According to this method, the fine fibrous tips clean the painted surface without damaging it, and the twisted parts have a waist, but the thin fibrous tips have twists. Since the fibers extend obliquely at an angle corresponding to the twist angle with respect to the length direction, the tip end is swollen from the twisted portion. For this reason, there is a problem in that the tip of the brush is entangled with a plurality of brushes and is caught on the protrusion of the automobile.

[0006]

In order to solve the above problems, in practice, it is necessary to make the brush material easy to cut, to make the thickness as small as possible, and to use the monofilament as a softening material for the brush material as much as possible. No measures have been taken.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a brush which does not damage the object to be cleaned and has excellent cleaning properties.

[0008]

Means for Solving the Problems The inventors of the present invention have made earnest studies to solve the above problems, and as a result, the base of the brush material is a multifilament, and the portion that does not directly contact the article to be cleaned is monofilament-shaped. The present inventors have found that these problems can be solved by having a shape and a shape in which a plurality of thin filaments are bundled in a portion that comes into direct contact with the object to be cleaned, and arrived at the present invention.

That is, the gist of the present invention is to provide a brush material characterized in that the tip portion is made of a synthetic fiber multifilament portion and the implant portion side is made of a synthetic fiber multifilament portion coated with a synthetic resin. It is a thing.

The present invention will be described in detail below. Figure 1
It is a schematic diagram of a brush material showing an example of the present invention. The tip portion of the brush material of the present invention comprises a synthetic fiber multifilament portion (1), and the planting portion side comprises a synthetic fiber multifilament portion (2) coated with a synthetic resin.

In the synthetic fiber multifilament portion (1) at the tip of the brush material, a plurality of thin filaments are converged,
It is virtually untwisted. Therefore, the contact with the object to be cleaned can be selected by changing the thickness of the single filament of the multifilament. Depending on the case, filaments having different thicknesses may be mixed. The length of the multifilament is not particularly limited, but is 10 to 100 mm.
The degree is a guideline, and the length may be set according to the purpose such as the size of the irregularities of the cleaning body and the structure of the brush. The diameter of single filament of multifilament is 60 to 25
The thickness is preferably about 0 μm, but is not particularly limited.

The synthetic fiber multifilament portion (2) coated with synthetic resin has a monofilament shape. The diameter of the synthetic fiber multifilament part coated with the synthetic resin is preferably about 1 to 2 mm, but is not particularly limited.

Polyamide, polyester, polyacrylic, etc. are suitable for the synthetic fiber multifilament. Polyolefin, polyurethane, polyvinyl chloride, etc. are suitable as the coating resin, but are not particularly limited.

Synthetic fiber multifilament part (1) and synthetic fiber multifilament part (2) coated with synthetic resin
As an example of a method for continuously forming the resin, there is a method in which the multifilament is coated with a resin and then cut into a certain length, and the resin coating layers at both ends are subjected to a certain length of stripping or dissolution removal treatment. At this time, when the synthetic fiber multifilament and the coating resin are combined with nylon for the synthetic fiber multifilament and polyethylene for the coating resin, the coating resin and the synthetic fiber multifilament do not adhere to each other, which facilitates strip processing. Another method is to cut the sea-island composite multifilament to a certain length and dissolve and remove the sea components at both ends.

[0015]

The brush material of the present invention has a relatively thick monofilament shape because most of the brush material is composed of a synthetic fiber multifilament portion coated with a synthetic resin. When this is used for the brush implantation part, it is elastic, has resilience, and the entanglement of the brush material hardly occurs.

On the other hand, the tip portion of the brush material is composed of a thin multifilament portion of a single yarn filament, and when this is used as a cleaning portion which directly contacts the object to be cleaned, the object to be cleaned is cleaned without damaging it. Moreover, since the multifilament portion is substantially in a non-twisted state and the filament extends straight in the same direction as the length direction, the entanglement of the hair tips hardly occurs. Moreover, since the tip of the brush material is thinned by the amount not covered with the synthetic resin, the brush material can be easily unwound even when the brush materials are entangled with each other.

[0017]

EXAMPLES Next, the present invention will be specifically described by way of examples. Example 1 60 denier (82 μm) single yarn made of nylon 6 resin
The surface of × 100 pieces was coated with a polyethylene resin by an extruder in the same manner as the electric wire coating. After the resin coating process, a product having a diameter of 1.6 mm was obtained. This was cut to a fixed length of 900 mm, and both ends were stripped by 80 mm to remove the polyethylene resin layer to obtain a brush material of the present invention. Comparative Example 1 A 4000 denier monofilament made of polyethylene resin and having a cross-shaped cross section was cut to a constant length of 900 mm to obtain a brush material. The diameter was about 1 mm at the longest part of the cross. Comparative Example 2 A brush material was obtained by cutting the uncoated polyethylene of Example 1 to a fixed length of 900 mm. Example 1, Comparative Examples 1, 2
The brush material obtained in 1. was planted in a U shape so that both ends were on the outside, and processed into a channel roll brush having an outer diameter of 1000 mm, and the car was washed as a car wash brush for evaluation.
In Example 1, the painted surface of the automobile was not scratched, and the stain was removed, so that the washability was excellent. In Comparative Example 1, the dirt was removed, but the paint surface of the automobile was scratched due to friction during cleaning. In Comparative Example 2, the brush materials are entangled during cleaning,
Could not be used.
