[0001] 本発明は、清掃部と柄部とからなる清掃用具及び該清掃用具における清掃部の製 造方法に関する。  The present invention relates to a cleaning tool including a cleaning unit and a handle, and a method of manufacturing the cleaning unit in the cleaning tool.
背景技術  Background art
[0002] タンス等の家具、ノ ソコンや照明器具等の電気製品、建物内部の壁、敷居、力も居 等についた埃を取り除くための清掃用具としては、従来からハタキが用いられてきた 。ハタキは、柄部の先端に複数の索状帯が取り付けられた構造を有し、前記索状帯 で埃がついた対象物の表面をはたくことにより、埃を取り去るというものである。従って 従来のハタキには拭き取るという機能がな力つたので、埃を大気中に撒き散らすこと なく取り去ることができな力つた。  [0002] Hataki has conventionally been used as a cleaning tool for removing dust attached to furniture such as a chest, electric appliances such as a noise control or a lighting fixture, walls inside a building, a sill, and power. Hataki has a structure in which a plurality of cord-like bands are attached to the tip of a handle, and dust is removed by striking the surface of a dusty object with the cord-like bands. Therefore, the conventional hagaki had the function of wiping it off, so it was not possible to remove dust without scattering it into the atmosphere.
[0003] このようなハタキの問題点を改良するために、拭き取り部とハタキ部を備えた清掃布 を柄部の先端のヘッドに取り付けてなる清掃用具 (特許文献 1)や、柄部とヘッド部と 清掃布力 なり、ヘッド部の中央に本体部を構成すると共に、本体部の周辺に薄肉 の可撓性部を形成してなるハンドワイパー (特許文献 2)等が提案されて ヽる。  [0003] In order to improve such a problem of the lettering, a cleaning tool (Patent Document 1) in which a cleaning cloth provided with a wiping part and a lettering part is attached to a head at the tip of a handle, a handle and a head For example, a hand wiper (Patent Document 2) has been proposed in which a main body is formed at the center of a head and a thin flexible portion is formed around the main body.
[0004] し力しながら特許文献 1に記載の清掃用具は、拭き取り部による汚れ拭き取り能力 が十分ではなぐ使い勝手も悪いものであった。また特許文献 2に記載のハンドワイ パーも、汚れ拭き取り能力が充分でないばかりか、狭い隙間における清掃を良好に 行うことはできな力つた。  [0004] In spite of this, the cleaning tool described in Patent Document 1 is not easy to use because the ability to wipe off dirt by the wiping portion is not sufficient. Further, the hand wiper described in Patent Document 2 is not only insufficient in dirt wiping ability, but also cannot clean satisfactorily in narrow gaps.
[0005] 本発明は上記課題を解決するためになされたもので、狭 、隙間における清掃にも 充分な清掃能力を発揮できる清掃用具を提供することを目的とする。  [0005] The present invention has been made to solve the above-described problem, and has as its object to provide a cleaning tool that can exhibit a sufficient cleaning ability even in cleaning a narrow space.

発明の開示  Disclosure of the invention
[0007] 本発明は、清掃部と柄部とからなる清掃用具であって、清掃部は、シート様繊維束 とシートとを接合して接合部を形成したシート重ね合わせ体を接合部に沿うように折り 曲げて嵩高部形成部を形成し、該嵩高部形成部を形成したシート重ね合わせ体が 嵩高部形成部を対面させるように折り曲げられて対向するシート様繊維束相互の当 接面が接合するように一体化されて形成され、前記嵩高部形成部の一端側に開口し た柄挿入口を有し、嵩高部形成部内部に形成された柄挿入部に柄部の支持棒を揷 入するようにしたことを特徴とする清掃用具である。 [0007] The present invention is a cleaning tool comprising a cleaning unit and a handle, and the cleaning unit is configured to join a sheet-like fiber bundle and a sheet together to form a bonded portion along a bonded portion. Fold like The bulky portion forming portion is formed by bending, and the laminated sheet body having the bulky portion forming portion is bent so as to face the bulky portion forming portion so that the contact surfaces of the sheet-like fiber bundles facing each other are joined. It has a handle insertion opening opened at one end side of the bulky part forming portion, and the support rod of the handle portion is inserted into the handle insertion portion formed inside the bulky portion forming portion. A cleaning tool characterized in that:
[0008] 本発明の清掃用具は、シート重ね合わせ体を折り曲げて対向するシート様繊維束 の当節面を部分的に接合して嵩高部形成部を形成し、この嵩高部形成部を形成し たシート重ね合わせ体をさらに折り曲げて対面するシート様繊維束の当接面を接合 して、嵩高部形成部の形成されて ヽる位置に一端側に開口した柄挿入口と柄挿入部 を嵩高に形成するように構成している。このためこの清掃用具は、幅細な形状に形成 することができ、したがって、幅狭い隙間にあるような塵や埃を効率よく搔き出すこと が可能となる。また、この清掃用具は、清掃部に繊維を束ねたシート様繊維束を用い ているから、幅狭な隙間の細い溝状部に埃が潜んでいても、そのような細い溝状部ま でシート様繊維束を構成する繊維を入り込ませ、その溝に潜む埃を効率よく搔き出し 、汚れの拭き取り能力に優れる。  [0008] The cleaning tool of the present invention bends the sheet-overlap body to partially join the opposing joint surfaces of the sheet-like fiber bundles to form a bulky portion forming portion, and forms the bulky portion forming portion. The abutted surfaces of the sheet-like fiber bundles facing each other are further folded by folding the overlapped sheet body, and the handle insertion opening and the handle insertion section opened at one end side at the position where the bulky portion forming portion is formed are bulky. Is formed. For this reason, this cleaning tool can be formed in a narrow shape, and therefore, it is possible to efficiently remove dust and dirt present in a narrow gap. In addition, since this cleaning tool uses a sheet-like fiber bundle in which fibers are bundled in the cleaning section, even if dust lurks in a narrow groove having a narrow gap, the cleaning tool extends to such a narrow groove. The fibers constituting the sheet-like fiber bundle are introduced, and the dust lurking in the grooves is efficiently extracted, and the dirt wiping ability is excellent.
[0009] また、この清掃用具は、シート重ね合わせ体を折り曲げることで柄挿入部を形成し ており、柄挿入部となる部品を清掃部とは別途に製作して配設する必要がなぐ清掃 用具を構成する部品の数を低減させることができる。  [0009] Further, in this cleaning tool, a pattern insertion portion is formed by folding a sheet-overlapping body, so that it is not necessary to manufacture and arrange a component to be the pattern insertion portion separately from the cleaning portion. The number of components constituting the tool can be reduced.
[0010] 本発明は、清掃部と柄部とからなる清掃用具であって、清掃部は、シート様繊維束 と、短冊状部を有するシートとを部分的に接合して接合部を形成したシート重ね合わ せ体を接合部に沿うように折り曲げて嵩高部形成部を形成し、該嵩高部形成部を形 成したシート重ね合わせ体が嵩高部形成部を対面させるようにシート様繊維束側を 内側にして折り曲げられてシート様繊維束相互の当接面が接合するように一体化さ れて形成され、前記嵩高部形成部の一端側に開口した柄挿入口を有し、嵩高部形 成部内部に形成された柄挿入部に柄部の支持棒を挿入するようにしたことを特徴と する清掃用具である。  [0010] The present invention is a cleaning tool comprising a cleaning portion and a handle portion, wherein the cleaning portion has a bonding portion formed by partially bonding a sheet-like fiber bundle and a sheet having a strip-shaped portion. The superimposed sheet is bent along the joining portion to form a bulky portion forming portion, and the sheet-like fiber bundle side is formed so that the superimposed sheet forming the bulky portion forming portion faces the bulky portion forming portion. It is bent inward and integrated so that the contact surfaces of the sheet-like fiber bundles are joined to each other, and has a handle insertion opening opened at one end side of the bulky portion forming portion, forming a bulky portion. A cleaning tool characterized in that a support rod of a handle portion is inserted into a handle insertion portion formed inside the portion.
[0011] この清掃用具によれば、上記したような幅細な形状に形成できて幅狭い隙間にある ような塵や埃を効率よく搔き出すことが可能となる効果や、構成する部品の数を低減 させることができる効果に加え、シートに設けられた短冊状部により、シート様繊維束 を構成する繊維では搔き出しきれない或る程度大きな埃を搔き出すことができ、一層 汚れの拭き取り能力が向上する。 [0011] According to this cleaning tool, it is possible to form the above-described narrow shape and efficiently remove dust and dirt present in a narrow gap. Reduce number In addition to the effects that can be achieved, the strip-shaped portion provided on the sheet allows a certain amount of dust, which cannot be exhausted by the fibers constituting the sheet-like fiber bundle, to be exhausted, thus further removing the dirt. Is improved.
[0012] 本発明の清掃用具においては、シート様繊維束が、複数枚のシート様繊維束を重 ねて形成されていてもよい。  [0012] In the cleaning tool of the present invention, the sheet-like fiber bundle may be formed by overlapping a plurality of sheet-like fiber bundles.
この清掃用具によれは、シート様繊維束として、シート様繊維束を複数枚重ね合わ せたものを用いることで、より多数の繊維によって効率よく埃を搔き出すことができる。  According to this cleaning tool, by using a sheet-like fiber bundle in which a plurality of sheet-like fiber bundles are stacked, dust can be efficiently extracted by a larger number of fibers.
[0013] 本発明の清掃用具においては、シート様繊維束は、多数の繊維力もなる第 1シート 様繊維束と、第 1シート様繊維束を構成する繊維よりも太い繊維力 なる第 2シート様 繊維束とを備えて構成されてもょ ヽ。  [0013] In the cleaning tool of the present invention, the sheet-like fiber bundle has a first sheet-like fiber bundle having a large number of fiber strengths and a second sheet-like fiber strength having a fiber strength larger than the fibers constituting the first sheet-like fiber bundle. It may be configured with a fiber bundle.
[0014] この清掃用具では、シート様繊維束は、第 1シート様繊維束と、この第 1シート様繊 維束を構成する繊維よりも太い繊維カゝらなる第 2シート様繊維束とを備えており、第 1 シート繊維束と第 2シート繊維束との間でコシの強さを違えるようにすることができる。 すなわち、シート様繊維束を構成する繊維の太さが太くなるとコシが強くなるから、第 2シート様繊維束のコシを強いものとすることができる。また、シート様繊維束を構成 する繊維の太さが細いほど、シート様繊維束にした際に、その繊維束のきめが細かく なる。これらのことから、この清掃用具では、コシの強い第 2シート様繊維束がより効 率よく埃を搔き出し、きめの細かい第 1シート様繊維束が、搔き出された埃を効率よく 取り込むように機能することができ、効率的な清掃を行うことができる。  [0014] In this cleaning tool, the sheet-like fiber bundle is composed of the first sheet-like fiber bundle and the second sheet-like fiber bundle made of a fiber fiber thicker than the fibers constituting the first sheet-like fiber bundle. The first sheet fiber bundle and the second sheet fiber bundle have different stiffness. That is, since the stiffness increases as the thickness of the fibers constituting the sheet-like fiber bundle increases, the stiffness of the second sheet-like fiber bundle can be increased. Further, as the thickness of the fibers constituting the sheet-like fiber bundle is smaller, the texture of the fiber bundle becomes finer when the sheet-like fiber bundle is formed. From these facts, in this cleaning tool, the stiff second sheet-like fiber bundles extract dust more efficiently, and the finer first sheet-like fiber bundles efficiently remove the extracted dust. It can function to capture and provide efficient cleaning.
[0015] 本発明の清掃用具において、シート様繊維束は、多数の繊維力もなる第 1シート様 繊維束と、第 1シート様繊維束を構成する繊維よりも太く且つ短い繊維からなる第 2シ ート様繊維束とを部分的に接合してなる構成を備えてもよい。  [0015] In the cleaning tool of the present invention, the sheet-like fiber bundle is composed of a first sheet-like fiber bundle having a large number of fiber strengths and a second sheet comprising fibers thicker and shorter than the fibers constituting the first sheet-like fiber bundle.

[0038] この清掃用具では、第 1シート様繊維束 7aと第 2シート様繊維束 7bは、第 1シート様 繊維束 7aを構成する繊維よりも、第 2シート様繊維束 7bを構成する繊維の方を短くし て構成されている。  [0038] In this cleaning tool, the first sheet-like fiber bundle 7a and the second sheet-like fiber bundle 7b are made of the fibers constituting the second sheet-like fiber bundle 7b rather than the fibers constituting the first sheet-like fiber bundle 7a. Is made shorter.
第 2シート要繊維束 7bを構成する繊維の長さは、第 1シート様繊維束 7aを構成する 繊維の長さより短ければ良いが、第 1シート様繊維束 7aを構成する繊維よりも lmm 一 10mm程度短!、ことが好まし!/、。  The length of the fiber constituting the second sheet required fiber bundle 7b may be shorter than the length of the fiber constituting the first sheet-like fiber bundle 7a, but may be 1 mm shorter than the fiber constituting the first sheet-like fiber bundle 7a. About 10mm short!
[0039] また、シート様繊維束 7が第 1シート様繊維束と第 2シート様繊維束を交互に重ね合 わせて構成される場合、シート様繊維束 7は、第 2シート様繊維束 7bを構成する腰の 強い太い繊維がより効率よく埃を搔き出し、第 1シート様繊維束 7aを構成する細い繊 維が搔き出された埃をより取り込むよう機能するため、清掃部 1は効果的に清掃を行 うことができるものになる。また、このようなシート様繊維束 7は、太い繊維が細い繊維 相互の絡み合 、の防止に寄与するよう機能できるため好ま 、。  When the sheet-like fiber bundle 7 is formed by alternately stacking the first sheet-like fiber bundle and the second sheet-like fiber bundle, the sheet-like fiber bundle 7 becomes the second sheet-like fiber bundle 7b. Since the thick fibers having a strong waist that constitutes the first sheet-like fiber bundle 7a function to extract dust more efficiently and the thin fibers that constitute the first sheet-like fiber bundle 7a function to take in the extracted dust more, the cleaning unit 1 Cleaning can be performed effectively. Further, such a sheet-like fiber bundle 7 is preferable because the thick fiber can function to contribute to the prevention of entanglement of thin fibers with each other.
[0040] 第 1シート様繊維束 7aを構成する繊維としては、上記したシート様繊維束と同様に 、例えば綿、毛等の天然繊維、ポリエチレン、ポリプロピレン、ポリエチレンテレフタレ ート、ナイロン、ポリアクリル等の合成繊維、芯鞘型繊維、海島型繊維、サイドバイサイ ド型繊維等の複合繊維等が用いられるが、熱融着性のある合成繊維や複合繊維が 好ましぐ特に芯がポリプロピレン、鞘がポリエチレン力もなる芯鞘型複合繊維は、鞘 を構成するポリエチレンの優れた熱融着性と、芯を構成するポリプロピレンの腰の強 さとを併せ持つため好ましい。第 2シート様繊維束 7bを構成する繊維としては、例え ば、ポリプロピレン、ポリエチレンテレフタレート、 PBT等の熱可塑性の繊維等が用い られる。第 1シート様繊維束 7a、第 2シート様繊維束 7bは、同一種類の繊維のみで構 成されていても、種類の異なる 2以上の繊維で構成されていてもよぐまた構成する繊 維の種類や太さの異同に関係なく色の異なる繊維を用いて構成することができる。ま た第 1シート様繊維束 7a、第 2シート様繊維束 7bは、夫々 2枚以上重ね合わせて用 いられてもよい。 [0040] The fibers constituting the first sheet-like fiber bundle 7a include, for example, natural fibers such as cotton and wool, polyethylene, polypropylene, polyethylene terephthalate, nylon, and polyacryl, similarly to the above-described sheet-like fiber bundle. Composite fibers such as synthetic fibers such as core-sheath type fibers, sea-island type fibers and side-by-side type fibers are used, and heat-fusible synthetic fibers and composite fibers are preferred. The core-sheath type composite fiber whose sheath also has a polyethylene force is preferable because it has both the excellent heat-fusibility of polyethylene constituting the sheath and the stiffness of polypropylene constituting the core. The fibers constituting the second sheet-like fiber bundle 7b include, for example, For example, thermoplastic fibers such as polypropylene, polyethylene terephthalate, and PBT are used. The first sheet-like fiber bundle 7a and the second sheet-like fiber bundle 7b may be composed of only the same type of fiber, or may be composed of two or more different types of fibers. It can be configured using fibers of different colors irrespective of the type and thickness of the fibers. Further, the first sheet-like fiber bundle 7a and the second sheet-like fiber bundle 7b may be used by overlapping two or more sheets.
[0041] 清掃部 1は、シート様繊維束 7とシート 9とを重ね合わせて形成されるシート重ね合 わせ体において、シート様繊維束 7とシート 9との重なりあう領域部分に接合部 10を 形成し、このシート重ね合わせ体をシート 9側を内側にして折り曲げて(図 4)シート様 繊維束 7同士を対面させて接合部 10に沿うように嵩高部形成部 3を形成し、更に嵩 高部形成部 3を形成したシート重ね合わせ体を長手方向一端側を他端側へ更に折り 曲げ、この折り曲げにより互いに対向するシート様繊維束 7相互の当接面の嵩高部 形成部 3付近を接合して接合部 11を形成して一体化されて ヽる(図 5)。  [0041] The cleaning unit 1 includes a joining unit 10 in a region where the sheet-like fiber bundle 7 and the sheet 9 overlap in a sheet-laminated body formed by overlapping the sheet-like fiber bundle 7 and the sheet 9. The sheet stack is folded with the sheet 9 side inward (FIG. 4) to form the bulky portion forming portion 3 along the joint portion 10 with the sheet-like fiber bundles 7 facing each other, and The sheet superposed body having the high portion forming portion 3 is further bent at one end in the longitudinal direction to the other end, and by this bending, the vicinity of the bulky portion forming portion 3 of the contact surface between the sheet-like fiber bundles 7 facing each other is opposed. It joins to form a joint 11 and is integrated (Fig. 5).
[0042] この清掃用具における清掃部 1は、次のように製造できる。  [0042] The cleaning unit 1 of this cleaning tool can be manufactured as follows.
図 2、図 3に示すように、シート様繊維束 7と、シート 9とを重ね合わせ、両者重なり合 う領域の部分 12の位置で接合する (便宜上、シート様繊維束 7とシート 9とを接合する 部分 12の領域を、斜線を付して示す。 ) o接合方法としては熱融着、接着、縫着等の 方法が挙げられるが、シート様繊維束 7とシート 9が熱融着可能な素材力も構成され ている場合には、加熱ローラ等により加熱加圧することで容易に接合一体化が可能 な熱融着により接合することが好ましい(以下、シート様繊維束 7とシート 9が熱融着 可能な素材よりなるものとして説明する。 ) oシート様繊維束 7とシート 9とを接合する 部分 12は、シート様繊維束 7の繊維方向と直交する方向に、シート様繊維束 7の中 心部を挟んだ部分に形成される。そして、図 3に示すように、シート様繊維束 7とシー ト 9とが重ね合わさるとともに部分 12で接合して、接合部 10の形成されたシート重ね 合わせ体 13aが構成される。接合部 10の形成されたシート重ね合わせ体 13aは、シ ート 9を内側に向けて折り曲げられるとともに、接合部 10の形成される方向に沿うよう に嵩高部形成部 3が形成される(図 4)。  As shown in FIGS. 2 and 3, the sheet-like fiber bundle 7 and the sheet 9 are overlapped and joined at the position of the portion 12 of the overlapping area (for convenience, the sheet-like fiber bundle 7 and the sheet 9 are joined together). The area of the joining portion 12 is indicated by diagonal lines.) O The joining method includes a method such as heat fusion, adhesion, and sewing, but the sheet-like fiber bundle 7 and the sheet 9 can be thermally fused. In the case where the material strength is also configured, it is preferable to join by heat fusion that can be easily joined and integrated by applying heat and pressure with a heating roller (hereinafter, the sheet-like fiber bundle 7 and sheet 9 are heat-bonded). The description will be made assuming that the sheet-like fiber bundle 7 and the sheet 9 are joined together.) The part 12 that joins the sheet-like fiber bundle 7 and the sheet 9 is formed in a direction orthogonal to the fiber direction of the sheet-like fiber bundle 7. It is formed at the center part. Then, as shown in FIG. 3, the sheet-like fiber bundle 7 and the sheet 9 are overlapped and joined at the portion 12 to form a sheet overlapped body 13a having the joint portion 10 formed. The sheet superimposed body 13a on which the joints 10 are formed is bent with the sheet 9 facing inward, and the bulky portion forming portions 3 are formed along the direction in which the joints 10 are formed (FIG. Four).
[0043] 次いでシート重ね合わせ体 13bの長手方向一端側を他端側へ折り曲げてシート重 ね合わせ体 13cが形成され、この折り曲げにより対面するシート様繊維束 7を互いに 当接する位置で接合して接合部 11を形成することで清掃部 1が得られる。この場合、 対面し合うシート様繊維束 7を嵩高部形成部 3近傍位置で互いに接合されることが好 ましい(図 5)。この際に熱融着法を採用すると、対面するシート様繊維束 7相互間の 他、シート様繊維束 7とシート 9との間を同時に接合することができる。 Next, one end in the longitudinal direction of the sheet stack 13b is bent toward the other end, and the sheet weight is reduced. A bonded body 13c is formed, and the sheet-like fiber bundles 7 facing each other are joined at the positions where they come into contact with each other by this bending to form a joint portion 11, whereby the cleaning portion 1 is obtained. In this case, it is preferable that the sheet-like fiber bundles 7 facing each other are joined to each other at a position near the bulky portion forming portion 3 (FIG. 5). At this time, if the heat fusion method is adopted, the sheet-like fiber bundle 7 and the sheet 9 can be simultaneously bonded in addition to the sheet-like fiber bundles 7 facing each other.
[0044] また、本発明の清掃用具における清掃部 1は、シート重ね合わせ体 13bの長手方 向一端側を他端側へ折り曲げてシート重ね合わせ体 13cを形成する際、この折り曲 げによって対面するシート様繊維束 7の間に、第 1シート繊維束 7aや第 2シート繊維 束 7bを重ね合わせてなる繊維束体 70を、繊維束体 70の少なくとも一方の繊維方向 先端部が嵩高部形成部 3より上方に位置するように介在させて構成してもよい(図 6) 。この場合、清掃部 1は、嵩高部形成部 3の上下いずれの方向にも第 1シート様繊維 束、第 2シート様繊維束の繊維方向先端部が向くように構成しているため、清掃用具 は、シート様繊維体 7による塵や埃の捕捉と同時に、嵩高部形成部 3よりも上方位置 にある塵や埃を繊維束体 70によって捕捉することができるものとなる。  Further, when the cleaning unit 1 in the cleaning tool of the present invention bends one end in the longitudinal direction of the sheet stack 13b to the other end to form the sheet stack 13c, the bending causes the cleaning unit 1 to face each other. The fiber bundle 70 formed by laminating the first sheet fiber bundle 7a and the second sheet fiber bundle 7b between the sheet-like fiber bundles 7 to be formed is formed into a bulky portion at the fiber end of at least one of the fiber bundles 70 in the fiber direction. It may be configured to be interposed so as to be located above part 3 (Fig. 6). In this case, since the cleaning unit 1 is configured such that the fiber-direction ends of the first sheet-like fiber bundle and the second sheet-like fiber bundle are directed in both directions above and below the bulky part forming unit 3, the cleaning tool is used. Thus, at the same time as dust and dirt are captured by the sheet-like fibrous body 7, dust and dirt located above the bulky portion forming part 3 can be captured by the fiber bundle 70.
なお、繊維束体 70は、第 1シート様繊維束 7aと第 2シート様繊維束 7bの重ね合わ せる枚数は限定されない。繊維束体 70が、多数枚の第 1シート様繊維束 7aや第 2シ ート様繊維束 7bを重ね合わせてなる場合、清掃用具は、嵩高部形成部 3よりも上側 に、第 1シート様繊維束 7aや第 2シート様繊維束 7bの構成繊維が多数存在する状態 を形成でき、嵩高部形成部 3よりも上側にある塵や埃をより効率良く捕捉できる。 また、繊維束体 70が、第 1シート繊維束 7aと第 2シート繊維束 7bとが交互に重ね合 わさって構成していると、既述したように、シート様繊維束 7は、第 2シート様繊維束 7b を構成する腰の強い太い繊維が効率よく埃を搔き出し、第 1シート様繊維束 7aを構 成する細い繊維が搔き出された埃を取り込むよう機能するため、清掃部 1は効果的に 清掃を行うことができるものになるため好ましい。  In the fiber bundle 70, the number of superposed first sheet-like fiber bundles 7a and second sheet-like fiber bundles 7b is not limited. When the fiber bundle body 70 is formed by stacking a large number of the first sheet-like fiber bundles 7a and the second sheet-like fiber bundles 7b, the cleaning tool is placed on the first sheet above the bulky portion forming section 3. It is possible to form a state in which a large number of constituent fibers of the fiber bundles 7a and the second sheet-like fiber bundles 7b are present, and it is possible to more efficiently capture dust and dirt above the bulky portion forming portion 3. Also, as described above, the sheet-like fiber bundle 7 includes the first sheet fiber bundle 7a and the second sheet fiber bundle 7b which are alternately overlapped with each other, as described above. The strong and thick fibers constituting the 2-sheet-like fiber bundle 7b efficiently extract dust, and the thin fibers constituting the first sheet-like fiber bundle 7a function to take in the extracted dust. The cleaning unit 1 is preferable because it can effectively perform cleaning.
[0045] また、本発明の清掃用具における清掃部 1は、シート様繊維束 7の外側にシート体 を重ね合わせて構成しても良い。この場合、このシート体とシート 9とでシート様繊維 束 7を挟み込むようにシート体を敷設してシート重ね合わせ体 13aを形成するとともに 、シート重ね合わせ体 13aを上記同様に折り曲げることにより清掃部 1を製造すること ができる。なお、シート体としては、不織布が好ましい。この場合、シート体とシート様 繊維束 7とシート 9が熱融着されることで容易に接合一体ィ匕してシート重ね合わせ体 13aを形成することができる。 Further, the cleaning unit 1 in the cleaning tool of the present invention may be configured by superposing a sheet body on the outside of the sheet-like fiber bundle 7. In this case, the sheet body is laid so that the sheet-like fiber bundle 7 is sandwiched between the sheet body and the sheet 9 to form the sheet superimposed body 13a, and the sheet superimposed body 13a is bent in the same manner as described above to thereby form the cleaning unit. Manufacturing one Can do. In addition, a nonwoven fabric is preferable as the sheet body. In this case, the sheet body, the sheet-like fiber bundle 7 and the sheet 9 are easily bonded and integrated by heat fusion to form the sheet superposed body 13a.
この清掃部 1は、シート体とシート 9によってシート様繊維束 7を挟み込むことによつ て、シート様繊維束 7全体としての形態を安定化させ、清掃用具を全体としてまとまり 良いものとすることができる。  The cleaning unit 1 stabilizes the overall form of the sheet-like fiber bundle 7 by sandwiching the sheet-like fiber bundle 7 between the sheet body and the sheet 9, so that the cleaning tool as a whole can be united well. Can be.
