Polishing power and durability are extremely important characteristics for polishing brushes. The polishing power can be increased by increasing the amount of abrasive. It is also important that the polishing brush does not lose its polishing power until it is polished. In other words, it is also important that the polishing power does not change when new and after use. That is, the following characteristics are important for an ideal polishing brush. Having strong frictional force. Do not lose strong polishing power until it wears out. have sufficient lifespan. However, it is extremely difficult for polishing brushes with conventional structures to satisfy all of these characteristics. Increasing the mixing ratio of abrasives to increase the polishing power has the disadvantage of shortening the service life. Also,
If the amount of abrasive is reduced in order to extend the service life, the abrasive power will be reduced and the abrasive power will be significantly reduced. In other words, the characteristics listed above that are important for polishing brushes are mutually contradictory characteristics, and
It is extremely difficult to satisfy these characteristics at the same time. For example, an abrasive brush in which abrasive threads with strong abrasive power are fixed to a base material is disclosed in Japanese Patent Application Laid-open No. 47091/1983. This polishing brush is molded with numerous abrasives embedded inside the polishing thread in order to increase the polishing power of the polishing thread. That is, in the process of mixing an abrasive material with a synthetic resin raw material for molding abrasive threads and molding the threads, the abrasive material is inserted into the threads. An abrasive thread with this structure has superior abrasive power compared to a thread in which no abrasive material is embedded inside. In particular, the abrasive thread having this structure can increase the filling rate of the abrasive material to increase the abrasive power. However, in the abrasive thread having this structure, when the filling rate of the abrasive material is increased, the strength of the thread is significantly reduced. The strength required of the abrasive thread limits the amount of abrasive filling. The abrasive thread that can actually be used is limited to a filling amount of abrasive material of 40% or less. If more abrasive material is filled, the tensile strength of the abrasive thread will be significantly reduced, making it impossible to use it as an abrasive brush. Also, abrasive threads have been developed in which an abrasive material is attached to the surface of synthetic fibers using a binder. The abrasive thread having this structure can adhere a large amount of abrasive material to the surface. However, there is a drawback that it is difficult to firmly adhere the abrasive material to the surface of the synthetic fiber. Abrasive materials that do not adhere strongly to the fibers will fall off the surface of the fibers in a short period of time during use. The abrasive power of the fibers on which the abrasive has fallen is significantly reduced. For this reason, the polishing thread has the disadvantage that its polishing ability decreases in a short period of time. In this abrasive thread, short fibers are mixed with a binder that adheres to the abrasive fibers in order to more firmly adhere the abrasive material. Although the short fibers firmly bind the binder layer mixed with the abrasive material, the abrasive material cannot be strongly attached to the fibers. For this reason,
Even if short fibers are mixed and the abrasive material is attached to the surface of the fibers, it is not possible to effectively prevent the abrasive material from falling off the fibers. However, in abrasive threads with this structure, the abrasive material is exposed on the surface, and the abrasive material creates countless irregularities on the surface of the fibers. This unevenness makes it easy for the abrasive to fall off during use. This is because the abrasive threads rub against each other during use. Polishing threads having a synthetic resin film provided on their surfaces have been developed to prevent the abrasive material from falling off even when the threads rub against each other (Japanese Patent Publication No. 3498/1983). The abrasive thread disclosed in this publication can prevent wear of the abrasive thread due to friction. However, the abrasive thread disclosed in this publication, like the above-mentioned abrasive thread, has the disadvantage that it cannot be filled with a large amount of abrasive material because the abrasive material is embedded inside the thread during the manufacturing process. This invention was developed with the aim of solving these drawbacks of conventional polishing brushes.The important purpose of this invention is to have excellent polishing power, and to have a low initial polishing power. The object of the present invention is to provide an ideal polishing brush that continues until worn out and has a sufficient lifespan.

Before developing the abrasive brush of this invention, the present inventor developed an abrasive thread that can firmly adhere an abrasive material (Japanese Patent Publication No. 53-28675). This polishing thread is
In order to strongly adhere the abrasive material, the surface of the thread serving as the base material is provided with irregularities. Compared to fibers with smooth surfaces, base yarns with irregularities have the advantage that abrasives can be attached to them in a state where they are less likely to fall off. For this reason,
This abrasive thread can have a long service life. However, this abrasive thread has the disadvantage that it is necessary to manufacture synthetic resin fibers with a special structure, which increases the cost of the base fibers. The inventor of this invention managed to make effective use of this technology to develop a technology that firmly adheres the abrasive material.
We repeated a huge number of prototypes. As a result, we succeeded in satisfying the above-mentioned characteristics with an extremely simple structure. In other words, conventional abrasive threads were designed to strongly attach the abrasive material to the fibers, or to increase the strength of the abrasive thread itself, but this invention
This method effectively utilizes the unevenness formed on the surface of the abrasive material attached to the base material to strengthen the bond between the abrasive materials. That is, the abrasive thread used in the abrasive brush of this invention is provided with a surface layer 4 in close contact with the unevenness formed on the surface of the abrasive grain layer 3, and the abrasive grain layer 3 is firmly bonded by the surface layer 4. In other words, unevenness is provided on the inner surface of the cylindrical surface layer 4, the abrasive grain layer 3 is provided with an unevenness that exactly matches the unevenness, and the unevenness of the abrasive grain layer 3 and the surface layer 4 are fitted into each other without any gaps. This is to firmly bond the abrasive grain layer 3.

In the abrasive thread having this structure, the base thread only needs to have sufficient strength to attach the abrasive grain layer, and is not required to have sufficient strength. Since the strength of the abrasive thread 1 is achieved by both the central base thread 2 and the surface layer 4, the surface layer 4 can be made thicker to significantly increase its tensile strength. Further, even if the abrasive grain layer 3 is thick, it can be attached without falling off because it is sandwiched between the base thread 2 and the surface layer 4. Therefore, the polishing force can be increased and the life span can be extended. Furthermore, the noteworthy feature of this structure of abrasive thread is that the thickness of the base thread, the amount of abrasive deposited, and the thickness of the surface layer can be adjusted to achieve the abrasive power and durability required for the abrasive brush. The ability to adjust the polishing strength and polishing force under wear conditions to the optimum state for the application. That is, in order to increase the polishing force, a large amount of abrasive material may be attached to the surface of the polishing thread. Even if a large amount of abrasive is attached, since the outside is covered with the surface layer 4 with matching irregularities and is attached to this, it can be firmly bonded and the durability will not deteriorate. Furthermore, in order to increase the polishing force in a worn state, the base thread 2 may be made of a material that is easily worn. The ideal base thread 2 should wear out when the abrasive material attached to its surface loses its abrasive power. In other words, if the base yarn 2 is too strong, it will not wear out even if the abrasive material on the surface loses its abrasive power, and the abrasive power will decrease. The strength of the abrasive thread 1 can be increased by using a weak base thread 2 for the abrasive thread 1 used in the abrasive brush of this invention. This is because both the base yarn 2 and the surface layer 4 achieve strong strength. Therefore, the strength of the base yarn 2 can be adjusted to be the same as the life of the abrasive material, as described above. Therefore, a long-life polishing brush can be realized without reducing the polishing power of the polishing thread.

Hereinafter, embodiments of this invention will be described based on the drawings. However, the example shown below is an example of an abrasive brush for embodying the technical idea of this invention, and the material, shape, structure, and arrangement of the component parts of the abrasive brush of this invention are as follows. It is not structure specific. Various changes can be made to the polishing brush of this invention within the scope of the claims for utility model registration. Furthermore, in order to make it easier to understand the scope of claims for utility model registration, this specification includes numbers corresponding to the members shown in the examples in the "column of claims for utility model registration",
Additional notes are added to the members shown in the "Column of Means for Solving Conventional Problems" and the "Column of Functions and Effects."
However, the members shown in the scope of the utility model registration claims are by no means limited to the members of the embodiments. In the polishing brush shown in FIG. 1, countless polishing threads 1 are planted on a base. As shown in FIG.
, an abrasive grain layer 3, and a surface layer 4. The base yarn 2 includes flexible synthetic resin fibers,
For example, the diameter is 0.1 to 5 mmφ, preferably 0.2 to 5 mmφ.
Polyethylene fibers, polypropylene fibers, polystyrene fibers, nylon fibers, etc. having a diameter of 1 mm can be used. By adjusting the material and thickness of the base yarn 2, its strength can be adjusted. The base thread 2 made of a thick and strong material extends the life of the polishing thread 1. On the contrary, the base thread 2, which is thin and easily abraded, reduces the decrease in polishing power during use. For this reason, the thickness and material of the base thread 2 are adjusted to optimal values in consideration of the required polishing force, life span, and life span of the abrasive material. The abrasive material in the abrasive grain layer 3 usually has a grain size of 20 to 3000.
No. 30 to No. 1000 are used.
As for the abrasive material, large particles are attached to the thick base thread 2, and small particles are attached to the thin fibers. For example, when monofilament polyethylene fibers with a diameter of 0.5 mm are used as the base thread 2, the abrasive material attached to the surface is usually of the number 100 to 500. The amount of abrasive material deposited is adjusted in consideration of the polishing force required of the polishing brush. Usually, the amount of the abrasive attached is adjusted to be 0.1 to 10 times, preferably 0.5 to 5 times, the weight of the base yarn 2. An abrasive material is attached to the surface of the base thread 2 using a binder to form an abrasive grain layer 3. The abrasive grain layer 3 is attached to the surface of the base thread 2 in a state where the surface is uneven. Therefore, a binder is applied to the surface of the base yarn 2, and when the binder is in an uncured state, an abrasive is attached to the surface. To thicken the abrasive grain layer 3, apply a binder and an abrasive material alternately.
The abrasive material is applied in multiple layers. As the binder to which the abrasive is attached, epoxy, nylon, urethane, or phenol adhesives may be used alone or in combination. The surface layer 4 is provided by applying synthetic resin to the surface of the abrasive grain layer 3. The thickness of the surface layer 4 is adjusted to an optimum value in consideration of the unevenness of the abrasive grain layer 3 and the required strength. When the abrasive grain layer 3 has large irregularities, the surface layer 4 is thickened to make the surface of the abrasive thread 1 smooth. The thickness of the surface layer 4 is usually 0.1 to 2 mm, preferably
It is adjusted within the range of 0.3 to 1 mm.
