A multifilament yarn of synthetic fiber is wound or knitted in a braided shape on the peripheral surface of the body, and the resin is set to form a second covering in a plurality of parallel aggregates of the monofilament yarn.

The multifilament yarn of the first covering and the multifilament yarn of the second covering are relatively thin in the former and thick in the latter such that the latter is thicker than the former or the former is thinner than the latter. Are preferred. This is because when the first and second coverings have this configuration, the durability of the brush bristle material or the bristle material is improved, and the polishing performance is further improved.

In the present invention, the synthetic resin monofilament yarn mixed with abrasive grains, which is a component of the brush bristle material or the bristle material, is provided with a multifilament yarn of synthetic fibers spirally wound or braided on the peripheral surface thereof.
A first cover ring is provided with the resin set.
For this reason, even if the second covering by the multifilament yarn is frayed due to the abrasion of the brush bristle material or the bristle material in the brush roll, the synthetic resin monofilament yarn mixed with a plurality of aggregated abrasive grains is rubbed together. do not do.

[0009] The existence of the resin-set multifilament yarn, which is the first covering, is based on the fact that the resin setting of the second covering by the multifilament yarn on the peripheral surface of a plurality of parallel aggregates of the synthetic resin monofilament yarn mixed with abrasive grains. The result is improved, and the reinforcing performance of the brush bristle material or the bristle material by the second covering is enhanced.

Therefore, according to the present invention, the service strength of the brush bristle material or the bristle material of the above-mentioned type can be considerably improved and the strength can be considerably improved as compared with the prior art.

The brush bristle material or bristle material according to the present invention has such characteristics, and is particularly suitable for use in strong polishing.

The brush bristle material or bristle material of the present invention has high durability and excellent strength, so that a thin synthetic resin monofilament yarn containing abrasive grains as a constituent element of the brush bristle material or bristle material can be used. . The application of a fine-grained synthetic resin monofilament yarn ensures that fine polishing is obtained. On the other hand,
Thin yarns or yarns are weak, and prior art thin yarns do not provide the required sufficient polishing. In contrast to this, in the present invention, fine polishing can be obtained by using a thin synthetic resin monofilament yarn mixed with abrasive grains. As the multifilament yarn of the first covering and the multifilament yarn of the second covering, a relatively thin one for the former and a thick one for the latter (the latter is thicker than the former or the former is thinner than the latter) are used. Thus, the strength of the bristle material or the bristle material is further improved.
