Abstract

PURPOSE:To keep elasticity in a whole brush for iron plate and to give it suit able stiffness by forming a core material with a braid, which is braided in a rope shape, and forming an sheathed cover with a braiding cover, which is knitted, etc. CONSTITUTION:For a sheathed brush material 1, the core material is formed with a braid 2 and the external sheathed cover is formed with a braiding cover 3. The braid 2 has about one - three mono-filaments 4 as unit fiber and the braid 2 is spirally braided in an S-shape or multiple-braided like a shoelace. Then, the braiding cover 3, which is the external cover, uses the fine fiber and it is mounted with being knitted in a tube shape around said braid 2. As the mono-filament to form the braid 2, the synthetic resin fiber of 0.8phi-1.0phi or the same synthetic resin fiber to obtain a grinding particle 7 such as polypropylene or nylon fiber as the suitable material is used. Then, such a mono-filament is braided in the range of 3-20 mono-filaments and the braid 2 is formed as the core material. As each unit fiber 5 to compose the braiding cover 3 as the external cover, namely, as the fiber of each mono-filament of compose the each unit fiber, the extremely fine synthetic resin fiber of 0.01phi-0.03phi degree is used.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a composite brush material suitable for use as a material for rotating brushes for polishing and cleaning iron plates and the like.

Prior Art The composite brush material for the above purpose is as shown in Fig. 1.
A very thick monofilament 1 is used as a core material and the surrounding area is covered with a multifilament braided covering 2, and a bundle 3 made of monofilaments arranged in parallel as shown in Fig. 2 is used as a core material, and the surrounding area is covered with a multifilament braided covering 2. A typical example is one covered with a braided covering 4.

In either case, a filament or the like containing abrasive particles 5 is used as the core material, and the outer sheath is coated (impregnated) with a resin.

Problems to be Solved by the Invention However, the former brush material with a very thick monofilament as a core material is not only unsuitable for relatively precise cleaning, but also causes excessive deterioration of the thin multifilament CWA assembly when used. Due to the high vibration of the thick monofilament (core material) and the resulting friction between the brush materials, the multifilament, which is not compatible with the core material, slips in a dumpling shape, causing breakage and hair breakage, which worsens the cleaning effect. However, it has the disadvantage of forming thin abrasive marks on the surface to be polished, making it difficult to perform uniform cleaning.

In addition, the latter method, in which a large number of monofilaments are aligned to form a core material, has a disadvantage that it is weak and causes significant ballast in the core material and outer sheath, resulting in significantly poor cleaning performance.

The present invention provides a novel composite brush with excellent cleaning performance that improves the drawbacks of the above-mentioned composite brushes.

Means for Solving the Problems The present invention provides, as the above-mentioned means, a composite brush material in which the core material is formed of a braided cord knitted in a lobe shape, and the outer cover is formed of a braided covering such as stockinette knitting. be.

Furthermore, the present invention provides a composite brush in which the core material is formed of a monofilament braid, and the outer sheath is formed of a braided covering made of multifilaments braided as unit fibers.

Function The above-mentioned core material (braid) improves the harmful hard elasticity of thick single core materials, and also improves the lack of elasticity (weakness) in composite brushes made of monofilaments arranged in parallel as core materials. The entire composite brush, which is a combination of a material) and a braided covering (outer covering), has soft elasticity and provides appropriate stiffness.

At the same time, both the core material of the braided structure and the outer sheath of the braided covering structure generate appropriate sagging, which together with the above-mentioned soft-elastic action significantly improves the cleaning effect. Particularly precise and uniform cleaning can be performed,
For example, it can cleanly polish down to the smallest pinhole, and it does not leave streaky polishing marks on the polished surface, making it ideal for finishing polishing of rolled iron plates, etc.

In addition, the combination of a braided cord (core material) and a braided covering (outer covering) can solve the problem of the balata of the core material in the above-mentioned aligned core material (therefore rusting the balata of the braided covering material) and the problem of the problem of the braided covering material in a thick single core material. To accurately prevent the problem of balata and maintain the above-mentioned cleaning effect favorably.

The above effects can be further improved by forming the core braid of relatively thick monofilaments and forming the outer braided covering of fine multifilaments as unit fibers.

Examples Examples of the composite brush according to the present invention will be described below with reference to FIGS. 3, 4, and 5.

The code is 1st. Used independently of Figure 2.

As described above, the core material of the composite brush material 1 is formed of the braided cord 2, and the outer sheath is formed of the braided covering 3. The braided cord 2, which is the core material, is made of a relatively thick monofilament 4 made of one to three monofilaments per iam, and is made into an S-shaped twist braid or multiple braids like a shoelace. The braid 2 is knitted in stockinette in a tube shape and covered.

As monofilaments forming the above-mentioned core braid 2, 0.08φ to 1.0φ synthetic WI woven fibers are synthetic resin fibers containing abrasive particles, and polypropylene or nylon fibers are used as suitable materials, and 3 to 3 fibers are used. A range of 20 pieces are knitted to form a braid 2 serving as a core material.

In addition, as each unit fiber 5 that composes the braided covering 3 that is the outer cover, that is, the six multifilament fibers that compose each unit fiber, ultrafine synthetic resin fibers of about 0.01φ to 0.03φ are used as suitable materials. Similarly, using polypropylene and nylon Ia 41, a large number of these fibers are formed into a paddle as a unit jJI fiber to form a braided covering 3 as an outer covering.

The thus formed braided cord (core material) 2 and braided covering (outer covering)
A composite brush 1 consisting of a combination of 3 is passed through a molten resin to apply a resin coating (impregnation). let

The monofilament 4 forming the braided cord 2, which is the core material, has high stiffness and abrasive effect, and the six multifilaments forming the braided covering 3, which is the outer cover, are extremely thin and have a rich sweeping effect.

Roll brushes and disk brushes are formed from the composite brush thus formed and used for polishing rolled iron plates and the like.

Effects of the Invention The above-mentioned core material (braid) improves the harmful hard elasticity of thick single core materials, and also corrects the lack of elasticity (weakness of III) in composite brushes made of monofilaments arranged in parallel as core materials. The entire composite brush, which is a combination of a braided cord (core material) and a braided covering (outer covering), has soft elasticity and is given appropriate stiffness.

At the same time, both the core material of the braided structure and the outer sheath of the braided covering structure generate appropriate sagging, which together with the above-mentioned soft-elastic action significantly improves the cleaning effect. Particularly precise and uniform cleaning can be performed,
For example, it can cleanly polish down to minute pinholes, and it does not leave streaky grinding marks on the polished surface, making it ideal for finishing polishing of rolled iron plates, etc. In addition, the combination of the braided cord (core material) and the braided covering (outer covering) ensures that the core material in the aligned core material does not disintegrate (thus causing the braided covering to disintegrate), and the braided covering in the thick single core material does not disintegrate. prevention and maintain the above-mentioned cleaning effect well.

The above effects can be further improved by forming the core braid of relatively thick monofilaments and forming the outer braided covering of fine multifilaments as unit fibers.
