Description
本発明は、研磨加工に用いられる研磨布に関し、特に、研磨性能を保証しつつその耐久性を向上させるための改良に関する。 The present invention relates to a polishing cloth used for polishing processing, and particularly relates to an improvement for improving durability while ensuring polishing performance.
研磨加工に用いられる研磨布が知られている。この研磨布は、例えば布状の基材の表面に粒状乃至粉状の研磨材が固着されたものであり、例えば、長手帯状の研磨ベルト、円盤状の研磨ディスク、或いはフラップホイールにおける翼片等がそれである。斯かる研磨布による研磨加工においては、ワークに対してその研磨布が摺接させられることで、そのワークにおける表面の仕上げ研磨等が行われる。例えば、特許文献１に記載された無端研磨ベルトがその一例である。 A polishing cloth used for polishing is known. This abrasive cloth is, for example, a granular or powdery abrasive fixed to the surface of a cloth-like base material, such as a longitudinal belt-like abrasive belt, a disc-like abrasive disc, or a blade piece in a flap wheel. That is it. In the polishing process using such a polishing cloth, the polishing cloth is brought into sliding contact with the work, whereby the surface of the work is subjected to finish polishing. For example, an endless polishing belt described in Patent Document 1 is an example.
しかし、前述したような従来の技術では、製品形状（帯状乃至円盤状等）への加工時や研磨加工における使用時等において、例えば研磨ベルトのスリットエッヂや研磨ディスクの外周端部等から繊維のほつれが発生し、研磨材を含む研磨層の脱落が発生したり、用途によってはほつれた繊維に起因してワークに傷をつける等の不具合が生じるおそれがあった。斯かる不具合を解消するために、従来は研磨布における布基材の表面に樹脂加工を行う等の対策がとられてきたが、上記不具合を十分には解消できなかった。このため、研磨性能を保証しつつ耐久性に優れた研磨布の開発が求められていた。 However, in the conventional technology as described above, when processing into a product shape (such as a band shape or a disk shape) or when used in polishing processing, for example, the slit edge of the polishing belt, the outer peripheral edge of the polishing disk, etc. There was a risk that fraying would occur and the polishing layer containing the abrasive might fall off, or that the workpiece could be damaged due to frayed fibers depending on the application. In order to solve such a problem, conventionally, measures such as performing resin processing on the surface of the cloth base in the polishing cloth have been taken, but the above problem cannot be solved sufficiently. For this reason, the development of a polishing cloth excellent in durability while guaranteeing the polishing performance has been demanded.
本発明は、以上の事情を背景として為されたものであり、その目的とするところは、研磨性能を保証しつつ耐久性に優れた研磨布を提供することにある。 The present invention has been made against the background of the above circumstances, and an object of the present invention is to provide a polishing cloth excellent in durability while guaranteeing polishing performance.
斯かる目的を達成するために、本発明の要旨とするところは、研磨材を保持する布状の基材を備えた研磨布であって、前記基材は、芯部の周囲にその芯部よりも融点の低い鞘部が設けられた熱融着糸を、経糸の少なくとも一部に用いた織物であることを特徴とするものである。 In order to achieve such an object, the gist of the present invention is an abrasive cloth provided with a cloth-like base material for holding an abrasive, and the base material has a core portion around the core portion. Further, the present invention is characterized in that it is a woven fabric in which a heat-sealing yarn provided with a sheath having a lower melting point is used for at least a part of the warp.
このようにすれば、前記基材は、芯部の周囲にその芯部よりも融点の低い鞘部が設けられた熱融着糸を、経糸の少なくとも一部に用いた織物であることから、経糸と緯糸とが強固に固着されることにより、繊維のずれ及び織布の伸びが抑えられるため、基材表面と研磨層との接着力の低下を好適に抑制できる。すなわち、研磨性能を保証しつつ耐久性に優れた研磨布を提供することができる。 In this way, since the base material is a woven fabric using a heat-sealed yarn provided with a sheath having a lower melting point than the core around the core, at least a part of the warp, Since the warp and the weft are firmly fixed, the displacement of the fiber and the elongation of the woven fabric can be suppressed, so that a decrease in the adhesive force between the substrate surface and the polishing layer can be suitably suppressed. That is, it is possible to provide a polishing cloth with excellent durability while ensuring polishing performance.
ここで、好適には、前記基材は、前記織物として織り上げられた状態において、前記熱融着糸における前記鞘部の少なくとも一部が加熱融着されたものである。このようにすれば、経糸と緯糸とが強固に固着されることに加え、熱加工時の温度条件によって経糸と緯糸との密着力の変化及び布の硬度（風合い）の調整が可能となり、薄い織布においても硬さ（こし）を与えることができる。 Here, preferably, the base material is obtained by heat-sealing at least a part of the sheath portion of the heat-sealing yarn in a state woven as the woven fabric. In this way, in addition to the warp and weft being firmly fixed, it is possible to adjust the change in the adhesion between the warp and the weft and the hardness (texture) of the fabric according to the temperature conditions during thermal processing, and the thinness Hardness can also be given to the woven fabric.
また、好適には、前記基材は、前記熱融着糸を経糸に１０％以上含む織物である。このようにすれば、経糸と緯糸とを必要十分な密着力で固着することができる。 Preferably, the base material is a woven fabric containing 10% or more of the heat fusion yarn in the warp. In this way, the warp and the weft can be fixed with a necessary and sufficient adhesion.
また、好適には、前記芯部は、ポリエステル繊維であり、前記鞘部は、その芯部よりも融点の低いポリエステル又はポリエチレンである。このようにすれば、実用的な材料から構成される熱融着糸を用いて、研磨性能を保証しつつ耐久性に優れた研磨布を提供することができる。 Preferably, the core is a polyester fiber, and the sheath is polyester or polyethylene having a melting point lower than that of the core. In this way, it is possible to provide a polishing cloth excellent in durability while guaranteeing polishing performance using a heat-sealing yarn composed of a practical material.
また、好適には、前記熱融着糸の芯部は、ポリエステル繊維によるフィラメント糸又は紡績糸である。このようにすれば、実用的な材料から構成される熱融着糸を用いて、研磨性能を保証しつつ耐久性に優れた研磨布を提供することができる。 Preferably, the core portion of the heat-sealing yarn is a filament yarn or spun yarn made of polyester fiber. In this way, it is possible to provide a polishing cloth excellent in durability while guaranteeing polishing performance using a heat-sealing yarn composed of a practical material.
また、好適には、前記基材は、経糸が１ｃｍあたり１１〜８０本、緯糸が１ｃｍあたり７〜６０本の組織で平織、綾織、又は繻子織とされた織物である。このようにすれば、研磨性能を保証しつつ耐久性に優れた実用的な態様の研磨布を提供することができる。 Preferably, the base material is a woven fabric having a plain weave, twill weave or satin weave with a structure of 11 to 80 warps per cm and 7 to 60 wefts per cm. If it does in this way, the polishing cloth of the practical aspect excellent in durability, ensuring polishing performance can be provided.
また、好適には、前記研磨布は、研磨ベルトに用いられるものである。このようにすれば、研磨性能を保証しつつ耐久性に優れた研磨ベルトを提供することができる。 Preferably, the abrasive cloth is used for an abrasive belt. In this way, it is possible to provide a polishing belt excellent in durability while guaranteeing polishing performance.
また、好適には、前記研磨布は、フラップホイールにおける翼片に用いられるものである。このようにすれば、研磨性能を保証しつつ耐久性に優れたフラップホイールを提供することができることに加え、熱融着糸の配合比率の調整により再生性（自生作用）のコントロールが容易になるという利点がある。 Preferably, the abrasive cloth is used for a blade piece in a flap wheel. In this way, it is possible to provide a flap wheel excellent in durability while guaranteeing polishing performance, and in addition, it becomes easy to control reproducibility (self-generated action) by adjusting the blending ratio of the heat-bonding yarn. There is an advantage.
以下、本発明の好適な実施例を図面に基づいて詳細に説明する。以下の説明に用いる図面において、各部の寸法比等は必ずしも正確には描かれていない。 Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

図４は、本実施例の研磨布１０における基材２４の製造方法の一例の要部を説明する工程図である。先ず、織布工程Ｐ１において、少なくとも一部に前記熱融着糸３０を用いた前記経糸２６と、前記緯糸２８とが、例えば経糸３０〜２００本／インチ（１１〜８０本／ｃｍ）、緯糸２０〜１５０本／インチ（７〜６０本／ｃｍ）の組織で平織、綾織、又は繻子織等の織物として織り上げられる。次に、ヒートセット工程Ｐ２において、前記織布工程Ｐ１にて織り上げられた織物が、例えばヒートセッタ等により１８０〜２００℃の温度で熱処理される。このヒートセット工程Ｐ２における熱処理温度は、前記鞘部３４の融点付近であり、且つ前記芯部３２の融点未満であることが望ましい。この熱処理において前記経糸２６における熱融着糸３０の鞘部３４の少なくとも一部が溶融させられ、更に熱処理後冷却されることで凝固（固化）される。すなわち、前記ヒートセット工程Ｐ２後の織物（基材２４）においては、前記経糸２６の熱融着糸３０における前記鞘部３４の少なくとも一部が融着されることで、その経糸２６の組織同士が相互に固着させられると共に、前記緯糸２８との接触部分において前記経糸２６と緯糸２８とが相互に固着させられる。このようにして得られた基材２４の表面に図示しない所定の研磨材が接着剤等により固着されることで前記研磨布１０が製造される。 FIG. 4 is a process diagram for explaining a main part of an example of a method for manufacturing the base material 24 in the polishing pad 10 of this embodiment. First, in the weaving process P1, at least a part of the warp yarn 26 using the heat-sealing yarn 30 and the weft yarn 28 are warp yarns of 30 to 200 yarns / inch (11 to 80 yarns / cm), for example, weft yarns. It is woven as a woven fabric such as plain weave, twill weave or satin weave with a structure of 20 to 150 pieces / inch (7 to 60 pieces / cm). Next, in the heat setting process P2, the woven fabric woven in the woven cloth process P1 is heat-treated at a temperature of 180 to 200 ° C. with a heat setter or the like, for example. The heat treatment temperature in the heat setting step P2 is preferably near the melting point of the sheath portion 34 and lower than the melting point of the core portion 32. In this heat treatment, at least a part of the sheath 34 of the heat fusion yarn 30 in the warp yarn 26 is melted, and further solidified (solidified) by cooling after the heat treatment. That is, in the woven fabric (base material 24) after the heat setting step P2, at least a part of the sheath portion 34 of the heat fusion yarn 30 of the warp yarn 26 is fused, so that the structures of the warp yarns 26 are mutually bonded. Are fixed to each other, and the warp yarn 26 and the weft yarn 28 are fixed to each other at a contact portion with the weft yarn 28. A predetermined abrasive (not shown) is fixed to the surface of the base material 24 thus obtained with an adhesive or the like, whereby the abrasive cloth 10 is manufactured.
図５は、従来の研磨布において通常用いられる、経糸及び緯糸に従来の一般的なポリエステル、綿の混紡糸を使用した織布（紡績糸）の裏面写真である。図６は、本実施例の研磨布１０に用いられる基材２４の裏面写真であり、前記経糸２６に前記熱融着糸３０を１００％使用すると共に、前記緯糸２８には一般的なポリエステル紡績糸を使用した織布である。また、図６に示す基材２４の糸組織としては、前記経糸２６が約１００本／インチ（約４０本／ｃｍ）、前記緯糸２８が約６０本／インチ（約２４本／ｃｍ）とされている。図７及び図８は、図６に示す本実施例の基材２４に熱処理を施すことで前記熱融着糸３０における鞘部３４が融着してゆく様子を示す裏面写真であり、図７は約１９０℃での加熱時、図８は約２００℃での加熱時の様子をそれぞれ示している。図６に示す状態から図７に示す状態、更には図８に示す状態への推移から明らかなように、熱処理（ヒートセット）における加熱温度の上昇に伴い前記基材２４における前記経糸２６の融着状態（融着の度合い）が強くなっていくことがわかる。熱処理において約２００℃での加熱を施した場合、図８に示すように前記経糸２６における低融点樹脂すなわち前記鞘部３４は略全て融着し、所謂モノフィラメントに近い状態となる。斯かる状態においては、前記経糸２６の繊維相互間が固着されていることに加え、前記緯糸２８との接触部分において前記経糸２６と緯糸２８とが強固に固着されている。 FIG. 5 is a photograph of the back side of a woven fabric (spun yarn) that uses a conventional mixed polyester / cotton yarn for warp and weft, which is usually used in a conventional polishing cloth. FIG. 6 is a backside photograph of the base material 24 used in the polishing pad 10 of this embodiment. The warp yarn 30 uses 100% of the heat-sealing yarn 30 and the weft yarn 28 is a general polyester spinning. A woven fabric using yarn. Further, as the yarn structure of the base material 24 shown in FIG. 6, the warp 26 is about 100 / inch (about 40 / cm), and the weft 28 is about 60 / inch (about 24 / cm). ing. 7 and 8 are backside photographs showing how the sheath portion 34 of the heat-fusible yarn 30 is fused by heat-treating the base material 24 of the present embodiment shown in FIG. FIG. 8 shows the state at the time of heating at about 190 ° C., and FIG. 8 shows the state at the time of heating at about 200 ° C., respectively. As is clear from the transition from the state shown in FIG. 6 to the state shown in FIG. 7 and further to the state shown in FIG. 8, the warp 26 melts on the base material 24 as the heating temperature rises in heat treatment. It can be seen that the wearing state (the degree of fusion) becomes stronger. When heating at about 200 ° C. is performed in the heat treatment, as shown in FIG. 8, the low-melting point resin in the warp 26, that is, the sheath portion 34 is almost completely fused and becomes a state close to a so-called monofilament. In such a state, in addition to the warp yarns 26 being fixed to each other, the warp yarns 26 and the weft yarns 28 are firmly fixed in contact with the weft yarns 28.
図９及び図１０は、ベルト状に加工された研磨布を実際の使用条件で使用した後のスリットエッヂ（スリット断面）を示す写真であり、図９は従来の一般的な布基材を用いた研磨布（図５に相当するもの）、図１０は本実施例の基材２４を用いた研磨布１０（図７に相当するもの）にそれぞれ対応する。図９に示すように、従来の一般的な布基材を用いた研磨布のスリット断面では、明らかに繊維がほつれており毛羽だったようになっていることがわかる。このように繊維がほつれた状態では、研磨材を含む研磨層の脱落が発生したり、用途によってはほつれた繊維に起因してワークに傷をつける等の不具合が生じるおそれがある。これに対し、図１０に示すように、本実施例の基材２４を用いた研磨布１０のスリット断面では、繊維のほつれはほとんど発生しておらず、良好な状態が保てていることがわかる。すなわち、本実施例の基材２４を用いた研磨布１０のスリット断面を従来技術のものと比較した場合、エッヂの状態に明らかな差異があり、本実施例の基材２４を用いた研磨布１０では繊維のほつれが好適に抑制されていることがわかる。 9 and 10 are photographs showing a slit edge (slit cross section) after using an abrasive cloth processed into a belt shape under actual use conditions, and FIG. 9 uses a conventional general cloth substrate. 10 corresponds to the polishing cloth 10 (corresponding to FIG. 7) using the base material 24 of this embodiment. As shown in FIG. 9, it can be seen that in the slit cross section of a polishing cloth using a conventional general cloth substrate, the fibers are clearly frayed and fluffy. In such a state where the fibers are frayed, there is a possibility that the polishing layer containing the abrasive may fall off or a defect such as scratching the workpiece due to the frayed fibers may be caused depending on applications. On the other hand, as shown in FIG. 10, in the slit cross section of the polishing pad 10 using the base material 24 of the present embodiment, the fibers are hardly frayed, and a good state can be maintained. Recognize. That is, when the slit cross section of the polishing pad 10 using the base material 24 of this example is compared with that of the prior art, there is a clear difference in the edge state, and the polishing cloth using the base material 24 of this example is used. 10 shows that fraying of the fibers is suitably suppressed.
続いて、本発明の効果を検証するために本発明者が行った試験について説明する。図１１は、この試験について概略的に示す斜視図である。この図１１において、前述した図１の構成と共通する部分については同一の符号を付してその説明を省略する。本発明者は、従来一般的であった布基材を用いた研磨布及び本実施例の基材２４を用いた研磨布１０それぞれを用いて、図１１に示すような研磨ベルト１２を作成した。すなわち、一般的なポリエステル、綿の混紡糸を経糸及び緯糸に用いると共に樹脂加工を施した織布である従来基材による研磨ベルトと、前記経糸２６に前記熱融着糸３０を１００％使用すると共に、前記緯糸２８には一般的なポリエステル紡績糸を使用した織布であり、織り上げられた状態で約１９０℃の熱処理が施された本実施例の基材２４である本発明基材による研磨ベルトとを用意した。本発明者は、斯かる従来基材及び本発明基材に関して、以下に示す試験条件で、前記研磨ベルト１２を駆動（循環）させた状態でスリットエッヂにガラス片３６の端面を接触させ、図１１に矢印で示す方向（研磨ベルト１２の幅方向）に押し込む試験を行った。 Subsequently, a test conducted by the present inventor in order to verify the effect of the present invention will be described. FIG. 11 is a perspective view schematically showing this test. In FIG. 11, the same reference numerals are given to portions common to the configuration of FIG. 1 described above, and the description thereof is omitted. The inventor made a polishing belt 12 as shown in FIG. 11 using the conventional polishing cloth using a cloth base material and the polishing cloth 10 using the base material 24 of this example. . That is, 100% of the heat-bonding yarn 30 is used for the warp 26 and a polishing belt made of a conventional base material which is a woven fabric obtained by using general polyester / cotton blended yarn for warp and weft and resin processing. In addition, the weft 28 is a woven fabric using a general polyester spun yarn, and is polished by the base material of the present invention which is the base material 24 of this embodiment that is heat-treated at about 190 ° C. in a woven state. A belt was prepared. The inventor brought the end face of the glass piece 36 into contact with the slit edge while driving (circulating) the polishing belt 12 under the test conditions shown below for the conventional base material and the base material of the present invention. A test was performed in which the test was performed in the direction indicated by the arrow 11 (the width direction of the polishing belt 12).

図１２は、前記試験の結果を示す表である。この図１２に示すように、従来一般的であった布基材である従来基材を使用した研磨ベルト（研磨布）では、５回転時点で微量の繊維のほつれが発生し、１０回転時点で前述した図９に示すような大量の繊維のほつれが発生した。この１０回転時点での繊維のほつれは継続使用が不可能なレベルのものと判断されたため、従来基材を使用した研磨ベルトに関しては斯かる時点で試験を中止した。一方、本実施例の基材２４である本発明基材を使用した研磨ベルト１２（研磨布１０）では、１００回転時点まで繊維のほつれが発生しなかった。２００回転時点で微量の繊維のほつれが発生したが、更に試験を継続したところ、４００回転時点でも繊維のほつれの程度は微量なものに留まり、継続使用が不可能なレベルにまで達することはなかった。以上の試験結果から、本実施例の基材２４である本発明基材を使用した研磨ベルト１２（研磨布１０）では、従来一般的であった布基材である従来基材を使用した研磨ベルトに比べて少なくとも１０倍の回転に耐えられる繊維ほつれ抑制効果が得られ、更に微量のほつれを許容すれば、従来技術に比べて４０倍以上の耐久性を示すことが確認できた。 FIG. 12 is a table showing the results of the test. As shown in FIG. 12, in a polishing belt (abrasive cloth) using a conventional base material which is a conventional cloth base material, a slight amount of fiber fraying occurs at the time of 5 rotations, and at the time of 10 rotations. A large amount of fraying as shown in FIG. 9 was generated. Since it was judged that the fraying of the fiber at the time of 10 rotations was a level at which continuous use was impossible, the test was stopped at this point for the polishing belt using the conventional base material. On the other hand, in the polishing belt 12 (polishing cloth 10) using the base material of the present invention which is the base material 24 of the present example, fraying of fibers did not occur until 100 revolutions. A trace amount of fiber fraying occurred at the time of 200 revolutions, but when the test was continued further, the degree of fiber fraying remained at a minute amount even at the time of 400 revolutions, and never reached a level where continuous use was impossible. It was. From the above test results, in the polishing belt 12 (polishing cloth 10) using the base material of the present invention which is the base material 24 of the present example, polishing using a conventional base material which is a cloth base material which has been conventionally common. It was confirmed that a fiber fraying suppression effect that can withstand at least 10 times the rotation compared to the belt was obtained, and if a slight amount of fraying was allowed, it was confirmed that the durability was 40 times higher than that of the prior art.
このように、本実施例によれば、前記基材２４は、芯部３２の周囲にその芯部３２よりも融点の低い鞘部３４が設けられた熱融着糸３０を、経糸２６の少なくとも一部に用いた織物であることから、経糸２６と緯糸２８とが強固に固着されることにより、繊維のずれ及び織布の伸びが抑えられるため、基材表面と研磨層との接着力の低下を好適に抑制できる。すなわち、研磨性能を保証しつつ耐久性に優れた研磨布１０を提供することができる。 As described above, according to the present embodiment, the base material 24 includes the heat-bonding yarn 30 provided with the sheath portion 34 having a melting point lower than that of the core portion 32 around the core portion 32. Since it is a woven fabric used for a part, the warp yarn 26 and the weft yarn 28 are firmly fixed, so that the displacement of the fiber and the elongation of the woven fabric are suppressed. The decrease can be suitably suppressed. That is, it is possible to provide the polishing pad 10 having excellent durability while ensuring the polishing performance.
前記基材２４は、前記織物として織り上げられた状態において、前記熱融着糸３０における前記鞘部３４の少なくとも一部が加熱融着されたものであるため、経糸２６と緯糸２８とが強固に固着されることに加え、熱加工時の温度条件によって経糸２６と緯糸２８との密着力の変化及び布の硬度（風合い）の調整が可能となり、薄い織布においても硬さ（こし）を与えることができる。更に、熱加工温度の上昇に伴い前記鞘部３４における低融点樹脂は略１００％溶融するため、前記基板２４の表面の平滑性が向上するという利点がある。 Since the base material 24 is woven as the woven fabric and at least a part of the sheath portion 34 of the heat-sealing yarn 30 is heat-sealed, the warp yarn 26 and the weft yarn 28 are firmly attached. In addition to being fixed, it is possible to change the adhesion between the warp yarns 26 and the weft yarns 28 and to adjust the hardness (texture) of the fabric according to the temperature conditions during the heat processing. be able to. Furthermore, since the low melting point resin in the sheath portion 34 melts approximately 100% as the heat processing temperature rises, there is an advantage that the surface smoothness of the substrate 24 is improved.
前記基材２４は、前記熱融着糸３０を経糸に１０％以上含む織物であるため、経糸２６と緯糸２８とを必要十分な密着力で固着することができる。 Since the base material 24 is a woven fabric containing 10% or more of the heat fusion yarn 30 in the warp yarn, the warp yarn 26 and the weft yarn 28 can be fixed with a necessary and sufficient adhesion.
前記芯部３２は、ポリエステル繊維であり、前記鞘部３４は、その芯部３２よりも融点の低いポリエステル又はポリエチレンであるため、実用的な材料から構成される熱融着糸３０を用いて、研磨性能を保証しつつ耐久性に優れた研磨布１０を提供することができる。 Since the core portion 32 is a polyester fiber, and the sheath portion 34 is polyester or polyethylene having a melting point lower than that of the core portion 32, using the heat-sealing yarn 30 composed of a practical material, It is possible to provide the polishing pad 10 having excellent durability while ensuring the polishing performance.
前記熱融着糸３０の芯部３２は、ポリエステル繊維によるフィラメント糸又は紡績糸であるため、実用的な材料から構成される熱融着糸３０を用いて、研磨性能を保証しつつ耐久性に優れた研磨布１０を提供することができる。 Since the core portion 32 of the heat-sealing yarn 30 is a filament yarn or spun yarn made of polyester fiber, the heat-sealing yarn 30 made of a practical material is used to ensure the polishing performance and make it durable. An excellent abrasive cloth 10 can be provided.
前記基材２４は、経糸２６が１ｃｍあたり１１〜８０本、緯糸２８が１ｃｍあたり７〜６０本の組織で平織、綾織、又は繻子織とされた織物であるため、研磨性能を保証しつつ耐久性に優れた実用的な態様の研磨布１０を提供することができる。 Since the base material 24 is a woven fabric having a warp 26 of 11 to 80 per cm and a weft 28 of 7 to 60 per cm in a plain weave, twill, or satin weave, it is durable while guaranteeing polishing performance. A polishing cloth 10 having a practical aspect with excellent properties can be provided.
前記研磨布１０は、研磨ベルト１２に用いられるものであるため、研磨性能を保証しつつ耐久性に優れた研磨ベルト１２を提供することができる。 Since the polishing cloth 10 is used for the polishing belt 12, it is possible to provide the polishing belt 12 having excellent durability while ensuring polishing performance.
以下、本発明の他の好適な実施例を図面に基づいて詳細に説明する。以下の説明において、実施例相互に共通する部分については同一の符号を付してその説明を省略する。 Hereinafter, other preferred embodiments of the present invention will be described in detail with reference to the drawings. In the following description, parts common to the embodiments are denoted by the same reference numerals and description thereof is omitted.
図１３は、本発明の一実施例である前記研磨布１０が用いられたフラップホイール４０について概略的に示す斜視図である。この図１３に示すように、本実施例のフラップホイール４０は、複数枚の翼片（フラップ）４２と、軸部（回転軸）４４とを、備え、前記複数枚の翼片４２が放射状に配設されると共にその中心部において前記軸部４４に固着されて構成されたものである。前記翼片４２は、前述した本実施例の研磨布１０である。以上のように構成されたフラップホイール４０は、前記軸部４４が軸心まわりに回転（自転）駆動させられた状態で、その軸部４４に追従して回転させられる前記複数枚の翼片４２が図示しないワークに接触（摺動）させられることで、そのワークの表面を研磨加工するものである。斯かるフラップホイール４０による研磨加工は、前記翼片４２の可撓性が大きいためワークの表面形状が比較的複雑な場合でも研磨加工が可能であり、また、研磨加工時に減耗した前記翼片４２（研磨布１０）の外周部は、その先端から順次飛散してゆくため、定常的に新しい研磨材が研磨加工に関与することとなり研磨性能が維持される。すなわち、研磨加工に係る研磨層の再生性（自生作用）を有する。 FIG. 13 is a perspective view schematically showing a flap wheel 40 using the polishing pad 10 according to an embodiment of the present invention. As shown in FIG. 13, the flap wheel 40 of this embodiment includes a plurality of blade pieces (flaps) 42 and a shaft portion (rotating shaft) 44, and the plurality of blade pieces 42 are radially arranged. It is arranged and fixed to the shaft portion 44 at the central portion thereof. The wing piece 42 is the polishing cloth 10 of this embodiment described above. The flap wheel 40 configured as described above has the plurality of blade pieces 42 that are rotated following the shaft portion 44 in a state where the shaft portion 44 is driven to rotate (spin) around the shaft center. Is brought into contact (sliding) with a workpiece (not shown), thereby polishing the surface of the workpiece. The polishing by the flap wheel 40 can be performed even when the surface shape of the workpiece is relatively complicated because of the large flexibility of the blade piece 42, and the blade piece 42 that has been worn out during the polishing process. Since the outer peripheral portion of the (abrasive cloth 10) is sequentially scattered from the tip, a new abrasive is constantly involved in the polishing process, and the polishing performance is maintained. That is, it has the reproducibility (self-generating action) of the polishing layer according to the polishing process.
図１４は、前記フラップホイール４０の翼片４２（研磨布１０）に好適に用いられる基材２４の裏面写真であり、前記経糸２６に前記熱融着糸３０を１００％使用すると共に、前記緯糸２８に前記熱融着糸３０を５０％、一般的なポリエステル紡績糸を５０％の割合で使用した織布である。また、図１４に示す基材２４の糸組織としては、前記経糸２６が約１００本／インチ（約４０本／ｃｍ）、前記緯糸２８が約７０本／インチ（約２８本／ｃｍ）とされ、２００℃程度の熱処理が施された状態を示している。この図１４に示すように、前記フラップホイール４０の翼片４２に適用される研磨布１０に用いられる基材２４としては、前記熱融着糸３０を、前記経糸２６及び緯糸２８それぞれの少なくとも一部に用いた織物であることが望ましく、そのようにすれば、前記経糸２６及び緯糸２８それぞれにおける前記熱融着糸３０の配合比率の調整、及び熱処理における温度の調整等により、従来の技術に比べて、前記フラップホイール４０の研磨加工に係る研磨層の再生性のコントロールが容易になる。 FIG. 14 is a photograph of the back surface of the base material 24 suitably used for the blade piece 42 (polishing cloth 10) of the flap wheel 40. The warp yarn 30 uses 100% of the heat fusion yarn 30 and the weft yarn. 28 is a woven fabric using 50% of the heat fusion yarn 30 and 50% of general polyester spun yarn. Further, as the yarn structure of the base material 24 shown in FIG. 14, the warp 26 is about 100 / inch (about 40 / cm), and the weft 28 is about 70 / inch (about 28 / cm). The state in which heat treatment at about 200 ° C. has been performed is shown. As shown in FIG. 14, as the base material 24 used in the polishing pad 10 applied to the blade piece 42 of the flap wheel 40, the thermal fusion yarn 30 is used as at least one of the warp yarn 26 and the weft yarn 28. It is desirable that the woven fabric used for the part, and by doing so, by adjusting the blending ratio of the heat fusion yarn 30 in each of the warp yarn 26 and the weft yarn 28 and adjusting the temperature in heat treatment, etc. In comparison, it becomes easier to control the reproducibility of the polishing layer related to the polishing of the flap wheel 40.
このように、本実施例によれば、前記研磨布１０は、フラップホイール４０における翼片４２に用いられるものであるため、研磨性能を保証しつつ耐久性に優れたフラップホイール４０を提供することができることに加え、熱融着糸３０の配合比率の調整により再生性（自生作用）のコントロールが容易になるという利点がある。 Thus, according to the present embodiment, since the polishing cloth 10 is used for the blade piece 42 in the flap wheel 40, it is possible to provide the flap wheel 40 excellent in durability while ensuring the polishing performance. In addition to being able to do this, there is an advantage that the regenerative property (self-generated action) can be easily controlled by adjusting the blending ratio of the heat fusion yarn 30.
