Description

【０００１】
【発明の属する技術分野】
本発明は、例えば保持具に保持されて清掃用モップとして使用され、または手で保持して使用される使い捨て可能な清掃用物品に係わり、特に埃やごみの捕捉効果が高く、また製造も容易な清掃用物品およびその製造方法に関する。
【０００２】
【従来の技術】
従来の室内清掃用などの清掃用物品として、以下の特許文献１ないし特許文献４に記載のものがある。
【０００３】
特許文献１に記載の清掃用シートは、網状シートにポリエステル繊維の繊維ウエッブが積層され、ウォータニードリング処理が施されて、繊維間が絡合されるとともに、この繊維が前記網状シートにも絡合されて、前記繊維が絡合された不織布が前記網状シートで補強されたものとなっている。特許文献２に記載の清掃用物品は、トウ（ＴＯＷ）から開繊された繊維束と、不織布のシートとが重ねられて、繊維束とシートとが融着線で接合されている。前記シートに複数の短冊片が分離して形成されており、前記繊維束と前記短冊片とで刷毛部が形成されている。
【０００４】
特許文献３に記載の拭き取り用具は、トウから開繊された繊維束と基材シートとが、繊維の延びる方向と直交する接合線で接合され、前記繊維が接合線の前後で切断されることにより、複数列の刷片部が形成されている。また、特許文献４に記載のダストモップは、複数本の帯状の不織布を編んで形成した複数の紐状の拭取材と中間連結材および基材とが縫合されて一体化され、複数の紐状の拭取材で水分や油分などを吸収できるものとなっている。

【特許文献４】

【０００６】
【発明が解決しようとする課題】
前記特許文献１に記載のものは、全体が実質的に平坦な不織布シートを主体としたものであるため、床などを拭いたときに、長辺および短辺の縁の部分に埃やごみが集中して付着しやすく、埃などが清掃面の中央部分に入り込みにくい。よって、全体として埃やごみの捕捉効率が悪く、また、側部分が埃やごみで早い時点に汚れるために、清掃面の中央部分が比較的汚れていないのにもかかわらず、廃棄して交換することが必要になる。
【０００７】
前記特許文献２に記載のものは、繊維束と短冊片の双方で埃やごみを補足できるため、不織布シートに比べて埃などの捕捉効率を向上させることができる。しかし、前記繊維束の縁と前記シートの縁が揃えられており、その結果、清掃面はほぼ平面形状であるため、清掃用物品の長辺および短辺の縁部分に埃などが集中して付着するのを避けることができず、清掃面の全域を必ずしも有効に利用できない。
【０００８】
次に、特許文献３と特許文献４に記載のものは、基材の清掃面側に、繊維束や紐状の拭取材による複数の刷片部が形成され、それぞれの刷片部で埃やごみを捕捉することが可能となっている。しかしながら、限られた大きさの清掃用物品に複数の刷片部が形成され、個々の刷片部が小さくなっているため、床面などの被清掃部との摩擦力により、前記刷片部が縒れたり捩れたりして、刷片部としての立体形状を長時間維持しにくい。
【０００９】
本発明は上記従来の課題を解決するものであり、埃やごみの捕捉効率が良い立体的な構造となり、しかも前記立体構造を形成しやすい清掃用物品およびその製造方法を提供することを目的としている。
【００１９】
本発明の清掃用物品の構成は、第１の清掃要素と第２の清掃要素が設けられて、それぞれの清掃要素は、外側縁とこの外側縁に対向する内側縁、および第１の表面と第２の表面を有しており、
第１の清掃要素と第２の清掃要素は、各清掃要素の第１の表面どうしが対面した状態で、外側縁と内側縁との間に位置する接合部で接合されて、それぞれの清掃要素は、外側縁と前記接合部との間の主部分と、前記接合部と内側縁との間の副部分とに区分されて、第１の清掃要素の副部分がその主部分の第２の表面に重ねられ、第２の清掃要素の副部分がその主部分の第２の表面に重ねられるように変形されて、
前記第１の清掃要素の主部分と第２の清掃要素の主部分とで前記主清掃要素が形成され、第１の清掃要素の副部分と第２の清掃要素の副部分とで前記副清掃要素が形成されているものである。
【００２０】
前記清掃用物品では、２種の清掃要素を対面させて接合し、その後に変形させるという簡単な工程で、主清掃要素に副清掃要素を重ねることができる。
【００２１】
この場合も本発明は、第１の清掃要素と第２の清掃要素は、前記繊維と、シートとを有し、前記シートに前記短冊片が形成され、この短冊片が前記副清掃要素に含まれているものとすることができる。
【００２２】
例えば、前記シートは、第１の清掃要素と第２の清掃要素のそれぞれの第１の表面に位置する基材シートである。
【００２３】
そして、把持面では、前記基材シートに保持シートが重ねられ、前記基材シートと前記保持シートとの間に、保持具を取り付けるための保持空間が形成されているものにできる。
【００２４】
清掃用物品の把持面に基材シートを位置させると、これに保持シートを重ねるなどして前記保持手段を簡単に構成することができる。
【００２５】
また本発明では、前記繊維は、トウ（ＴＯＷ）から開繊されたものであり、第１の清掃要素と第２の清掃要素のそれぞれにおいて、前記繊維が外側縁から内側縁まで連続して延びているものである。
【００２６】
トウから開繊された繊維束を拡幅させてシート状とすることにより、前記繊維の束を簡単に形成することができる。
【００２７】
次に、本発明は、被清掃部を拭く拭き面と、前記拭き面と逆側の把持面とを有する清掃用物品の製造方法において、
（ａ）共に第１の表面と第２の表面とを有する第１の清掃要素と第２の清掃要素とを、第１の表面どうしを対面させて接合部で接合する工程と、
（ｂ）それぞれの清掃要素に外側縁およびこの外側縁に対向する内側縁を形成し、それぞれの清掃要素を、外側縁と前記接合部との間の主部分と、前記接合部と内側縁との間の副部分とに区分する工程と、
（ｃ）第１の清掃要素の副部分をその主部分の第２の表面に重ね、第２の清掃要素の副部分をその主部分の第２の表面に重ねて、把持面側に第１の清掃要素の主部分と第２の清掃要素の主部分から成る主清掃要素が位置し、前記清掃面側に第１の清掃要素の副部分と第２の清掃要素の副部分から成る副清掃要素が位置し、それぞれの副部分の内側縁が外側縁と接合部との間に位置するように変形させる工程と、
を有することを特徴とするものである。
【００２８】
この清掃用物品の製造方法では、第１の清掃要素と第２の清掃要素を重ねて接合させて変形させるだけで、主清掃要素の側縁の内側に副清掃要素の側縁が位置するものとなる。よって、それぞれが独立した主清掃要素と副清掃要素とを積層させる製造方法に比べて、主清掃要素と副清掃要素とのずれを防止しやすい。
【００２９】
本発明は、第１の清掃要素を形成するための第１の帯状材料と、第２の清掃要素を形成するため第２の帯状材料を繰り出して互いに重ね、
前記（ａ）の工程で、前記帯状材料の繰り出し方向（ＭＤ）と交叉する前記接合部を形成し、
前記（ｂ）の工程で、前記第１の帯状材料と第２の帯状材料とを、第１の表面どうしが対面した状態で、前記接合部の繰り出し方向の前方および後方で一緒に切断して、前記外側縁と前記内側縁を形成する。
【００３０】
このように連続工程で多数の清掃用物品を順に製造することができる。
例えば、本発明は、前記第１の帯状材料と前記第２の帯状材料は、その繰り出し方向に延びる繊維、複数の糸体、複数の短冊片の少なくとも１つを有している。
【００３１】
また、本発明は、前記第１の帯状材料と前記第２の帯状材料は、トウ（ＴＯＷ）から開繊された繊維と、帯状シートとを有し、前記工程（ａ）の前に、前記帯状シートを切断して複数の短冊片を形成する工程が含まれている。
【００３２】
また、前記帯状シートは、前記第１の帯状材料と前記第２の帯状材料のそれぞれの第１の表面に位置し、製造された清掃用物品では、把持面側に前記帯状シートから切断された基材シートが位置し、前記副清掃要素に、前記帯状シートから切断された短冊片が位置するものとなる。
【００３３】
【発明の実施の形態】
図１は第１の本発明の第１の実施の形態である清掃用物品を把持面を上に向けた斜視図、図２は前記清掃用物品を拭き面を上に向けた斜視図、図３（Ａ）（Ｂ）および図４は清掃用物品の組み立て状態を示す斜視図、図５（Ａ）（Ｂ）は短冊片および繊維集合体を示す拡大斜視図、図６は清掃用物品が保持具に取付けられた状態を示す斜視図、図７は図６のＶＩＩ−ＶＩＩ矢視の断面拡大図、図８は前記清掃用物品の製造方法の説明図である。
【００３４】
この第１の実施の形態の清掃用物品１は、図１において上に向けられているのが把持面２であり、図２において上に向けられているのが拭き面３である。
【００３５】
この清掃用物品１は、把持面２側に主清掃要素５が位置し、拭き面３側に副清掃要素６が位置している。主清掃要素５は、Ｙ方向の長さ寸法がＸ方向の長さ寸法よりも長い長方形であり、副清掃要素６も、Ｙ方向の長さ寸法がＸ方向の長さ寸法よりも長い長方形である。前記主清掃要素５と前記副清掃要素６は、Ｙ方向に延びる中心線Ｏ−Ｏに沿って形成された第１の接合部７によって区分されている。
【００３６】
後に説明する製造方法においては、図３に示すように、Ｘ方向が個々の清掃用物品１を製造する際の送り方向すなわち繰り出し方向（ＭＤ：Machine Direction）であり、Ｙ方向が前記繰り出し方向と直交する方向（ＣＤ：Cross Direction）である。
【００３７】
主清掃要素５は、互いに平行に対向してＹ方向（長辺方向）に延びる外側縁１０Ａと外側縁２０Ａを有し、副清掃要素６も、互いに平行に対向してＹ方向（長辺方向）に延びる内側縁１０Ｂと内側縁２０Ｂを有している。前記外側縁１０Ａ，２０Ａおよび前記内側縁１０Ｂ，２０Ｂは、前記中心線Ｏ−Ｏと平行であり、清掃用物品１は前記中心線Ｏ−Ｏを挟んで対称に位置している。
【００３８】
図２に示すように、拭き面３側では、主清掃要素５に副清掃要素６が重ねられており、副清掃要素６の内側縁１０Ｂ，２０Ｂは、それぞれ前記主清掃要素５の外側縁１０Ａ，２０Ａと前記第１の接合部７との中間に位置している。副清掃要素６の内側縁１０Ｂ，２０Ｂは、前記主清掃要素５の外側縁１０Ａ，２０Ａと前記第１の接合部７との中心に位置していてもよいし、いずれか偏って位置してもよい。
【００３９】
図１に示すように、第１の接合部７から外側縁２０Ａ（または外側縁１０Ａ）までの距離をＬ１とし、内側縁２０Ｂ（または内側縁１０Ｂ）から外側縁２０Ａ（または外側縁１０Ａ）までの距離をＬ２とすると、Ｌ２はＬ１の１／４以上で３／４以下が好ましく、さらには１／３以上で２／３以下が好ましい。
【００４０】
前記副清掃要素６は、第１の接合部７から内側縁１０Ｂまでの部分、および第１の接合部７から内側縁２０Ｂまでの部分が、それぞれ主清掃要素５に拘束されておらず前記各部分は自由に動けるようになっている。この清掃用物品１では、主清掃要素５の外側縁１０Ａと２０Ａ、および副清掃要素６の内側縁１０Ｂ，２０Ｂが互いに独立して自由に動けるため、拭き面３で床面などの被清掃部を拭くと、前記外側縁１０Ａ，２０Ａと内側縁１０Ｂ，２０Ｂが互いに独立して埃やごみを払拭したり捕集する機能を発揮する。
【００４１】
なお、前記主清掃要素５が外側縁１０Ａ，２０Ａを含むＸ方向の所定長さの範囲で自由に動くことができ、副清掃要素６が内側縁１０Ｂ，２０Ｂを含むＸ方向の所定長さの範囲で自由に動くことができるならば、第１の接合部７と内側縁１０Ｂとの間、および第１の接合部７と内側縁２０Ｂとの間で、さらに主清掃要素５と副清掃要素６とが部分的に接合されていてもよい。あるいは、副清掃要素６の全体が主清掃要素５に接合されて、主清掃要素５の外側縁１０Ａ，２０Ａだけが自由に動くものであってもよい。
【００４２】
前記副清掃要素６が主清掃要素５に対して部分的にまたは全体的に接合されているものでは、清掃時に副清掃要素６が主清掃要素５からめくれるのを防止でき、図２に表れている副清掃要素６の表面を、清掃面として有効に使用することができる。
【００４３】
この清掃用物品１は、第１の清掃要素１０と第２の清掃要素２０とが組み合わされて構成されている。図３（Ａ）は、第２の清掃要素２０が組み立てられた状態を示し、図３（Ｂ）は、第１の清掃要素１０を分解して示し、図４は、第１の清掃要素１０と第２の清掃要素２０とが第１の接合部７で接合された状態を示している。
【００４４】
図３（Ｂ）に示すように、第１の清掃要素１０は、前記外側縁１０Ａと内側縁１０Ｂおよび短辺である端縁１０Ｄと端縁１０Ｅを有する長方形状であり、第１の表面１０Ｆおよびこれと逆側の第２の表面１０Ｇを有している。図３（Ｂ）では、第１の表面１０Ｆが上に向けられている。
【００４５】
第１の清掃要素１０は、第２の表面１０Ｇに、シート状の繊維集合体３１が位置し、第１の表面１０Ｆ側では、前記繊維集合体３１に基材シート３２が重ねられ、さらに基材シート３２の上に、Ｙ方向へ間隔を空けて保持シート３３，３３が重ねられている。
【００４６】
前記基材シート３２には、外側縁１０ＡからＸ方向へ向けて所定範囲までギザ状の切り込み３２ａが形成されており、このギザ状の切り込み３２ａは、Ｙ方向へ等間隔を空けてあるいはランダムな間隔を空けて形成されている。そして基材シート３２には、前記切り込み３２ａで分離された複数の短冊片３２ｂが形成されている。前記保持シート３３，３３には、前記基材シート３２に重ねられた状態で、前記切り込み３２ａと一緒に切り込み３３ａが形成され、この切り込み３３ａで分離された複数の短冊片３３ｂが形成されている。前記短冊片３２ｂと短冊片３３ｂは、第１の清掃要素１０の外側縁１０Ａにおいて、互いに分離されて独立して動けるようになっている。
【００４７】
また基材シート３２には、内側縁１０ＢからＸ方向へ向けて所定範囲までギザ状の切り込み３２ｄが形成され、前記切り込み３２ｄで分離された複数の短冊片３２ｅが形成されている。同様に、保持シート３３，３３にも、前記切り込み３２ｄと一緒に切り込まれた切り込み３３ｄが形成されて、複数の短冊片３３ｅが形成されている。内側縁１０Ｂでは、前記短冊片３２ｅと短冊片３３ｅが互いに分離されて独立して動けるようになっている。
【００４８】
前記第１の清掃要素１０は、前記繊維集合体３１と基材シート３２および保持シート３３，３３が重ねられた状態で、第２の接合部８によって一緒に接合されている。この実施の形態では、繊維集合体３１と基材シート３２および保持シート３３，３３が熱可塑性樹脂材料を主体として形成されているため、前記第２の接合部８において、これらが互いにヒートシールまたは超音波シールされている。
【００４９】
前記第２の接合部８は、外側縁１０Ａから離れた位置でＹ方向に沿って形成されており、その中央部分は外側縁１０Ａに凸側が向けられた湾曲線形状である。なお、図３（Ｂ）では、繊維集合体３１と基材シート３２および保持シート３３，３３が分解されて示されているため、前記第２の接合部８を破線で示している。図１に示すように、前記第２の接合部８は連続線である。あるいは第２の接合部８が間欠線状に形成されていてもよい。なお、前記第２の接合部８が縫合や接着剤による接着で形成されてもよい。
【００５０】
図３（Ａ）に示すように、第２の清掃要素２０は前記第１の清掃要素１０と面対称の形状および構造である。第２の清掃要素２０も、前記外側縁２０Ａと内側縁２０Ｂおよび端縁２０Ｄと端縁２０Ｅを有する長方形状であり、第１の表面２０Ｆおよびこれと逆側の第２の表面２０Ｇを有している。図３（Ａ）では、第２の表面２０Ｇが上に向けられている。
【００５１】
第２の清掃要素２０は、第２の表面２０Ｇに、繊維集合体３１が位置し、第１の表面２０Ｆでは、前記繊維集合体３１に基材シート３２が重ねられ、さらに基材シート３２に、Ｙ方向に間隔を空けて保持シート３３，３３が重ねられている。前記第１の清掃要素１０と同様に、第２の清掃要素２０においても、外側縁２０Ａでは、基材シート３２に短冊片３２ｂが形成され、保持シート３３，３３に短冊片３３ｂが形成されている。また内側縁２０Ｂにおいても、基材シート３２に短冊片３２ｅが形成され、保持シート３３，３３に短冊片３３ｅが形成されている。
【００５２】
第２の清掃要素２０では、繊維集合体３１と基材シート３２および保持シート３３，３３が重ねられた状態で、第２の接合部９によってこれらが一緒に接合されている。この第２の接合部９は、前記第１の清掃要素１０に形成された第２のの接合部８と同じ構造で同じ形状である。
【００５３】
図４に示すように、前記第１の清掃要素１０と第２の清掃要素２０は、共に平坦な状態で、各清掃要素１０，２０の第１の表面１０Ｆと第１の表面２０Ｆとが対面した状態に重ねられ、第１の清掃要素１０と第２の清掃要素２０とが、前記第１の接合部７において互いに接合される。第１の接合部７は、前記第２の接合部８，９と、内側縁１０Ｂ，２０Ｂとの間でＹ方向に直線的に形成される。
【００５４】
第１の清掃要素と第２の清掃要素２０が、熱可塑性樹脂材料を主体として構成されている場合には、ヒートシールまたは超音波シールにより前記第１の接合部７が形成される。または、前記第１の清掃要素１０と第２の清掃要素２０とが重ねられて縫合され、前記第１の接合部７が形成されてもよい。
【００５５】
前記第１の接合部７が形成されると、第１の清掃要素１０は、第１の接合部７から外側縁１０Ａまでの主部分５Ａと、第１の接合部７から内側縁１０Ｂまでの副部分６Ａとに区分される。また第２の清掃要素２０は、第１の接合部７から外側縁２０Ａまでの主部分５Ｂと、第１の接合部７から内側縁２０Ｂまでの副部分６Ｂとに区分される。
【００５６】
この清掃用物品１は、前記第１の接合部７が形成された後に、図１と図２に示すように、第１の清掃要素１０の前記主部分５Ａと第２の清掃要素２０の主部分５Ｂとがほぼ平面となるように展開されて前記主清掃要素５が形成される。また、前記第１の清掃要素１０の副部分６Ａが、主部分５Ａの第２の表面１０Ｇに重なるように変形させられ、第２の清掃要素２０の副部分６Ｂが、主部分５Ｂの第２の表面２０Ｇに重なるように変形させられて、前記副部分６Ａと前記副部分６Ｂとで、前記副清掃要素６が形成される。
【００５７】
図１に示すように、清掃用物品１の把持面２には、第１の清掃要素１０の第１の表面１０Ｆおよび第２の清掃要素２０の第１の表面２０Ｆが現れている。この把持面２では、Ｙ方向に間隔Ｗａを空けて、幅寸法がＷｂの前記保持シート３３，３３が現れる。第１の接合部７と第２の接合部８とで挟まれた部分において、基材シート３２と保持シート３３，３３との間に、保持空間４１Ａ，４１Ａが形成され、第１の接合部７と第２の接合部９とで挟まれた部分において、基材シート３２と保持シート３３，３３との間に、保持空間４１Ｂ，４１Ｂが形成されている。この実施の形態では、この保持空間４１Ａ，４１Ａおよび保持空間４１Ｂ，４１Ｂが保持手段を構成している。
【００５８】
図１に示すように、把持面２には、外側縁１０Ａおよび外側縁２０Ａと、前記第２の接合部８，９との間の領域に、基材シート３２の一部が切断された複数の短冊片３２ｂと、保持シート３３の一部が切断された複数の短冊片３３ｂとが現れており、これら短冊片３２ｂ，３３ｂと前記繊維集合体３１とが、前記領域で自由に動けるように存在している。
【００５９】
図２に示すように、拭き面３には副清掃要素６が現れているが、この副清掃要素６の表面では、中央の前記間隔Ｗａの範囲に、基材シート３２から切断された短冊片３２ｅが現れ、その両側の幅寸法Ｗｂの領域では、基材シート３２から切断された前記短冊片３２ｅと前記保持シート３３から切断された短冊片３３ｅとが重ねられて且つ互いに独立して自由に動くように現れている。そして各短冊片３２ｅ，３３ｅの下に繊維集合体３１が位置している。さらに副清掃要素６の両側に、主清掃要素５を形成している前記繊維集合体３１が現れている。
【００６０】
前記副清掃要素６を構成している短冊片３２ｅ，３３ｅおよび繊維集合体３１は、互いに独立して自由に動くことができる。また主清掃要素５と副清掃要素６は互いに独立して動くことができるようになっており、図７に示すように、主清掃要素５と副清掃要素６との間にはポケット部４３，４３が形成されている。
【００６１】
図６は、前記清掃用物品１が、保持具５０に保持された状態を示している。
図６に示す保持具５０は、ロッド５１と、清掃用物品１を保持する保持体５５と、前記ロッド５１と保持体５５を連結する連結部材５３を有している。ロッド５１と連結部材５３は軸５２により回動自在に連結されており、連結部材５３と保持体５５は、前記軸５２と直交して配置された軸５４により回動自在に連結されている。その結果、前記保持体５５に対してロッド５１が各方向へ自由に倒れることができるようになっている。
【００６２】
前記保持体５５は、楕円形状または長円形状であり、長径方向に向く中心線に沿って両側から切断部５６，５６が形成され、切断部５６，５６によって保持爪５７Ａ，５７Ａと保持爪５７Ｂ，５７Ｂとが分離されている。
【００６３】
図６と図７に示すように、前記保持爪５７Ａ，５７Ａが、清掃用物品１の前記保持空間４１Ａ，４１Ａに挿入され、前記保持爪５７Ｂ，５７Ｂが前記保持空間４１Ｂ，４１Ｂに挿入されて、保持体５５によって清掃用物品１の把持面２が保持される。
【００６４】
保持具５０に装着された清掃用物品１は、拭き面３が床面などの被清掃部に当てられ、前記ロッド５１を保持して被清掃部に沿って清掃用物品１を移動させて清掃作業が行われる。清掃用物品１をＸ方向へ移動させると、主清掃要素５を構成している繊維集合体３１によって被清掃部の埃やごみが捕捉され、さらには主清掃要素５の外側縁１０Ａ，２０Ａに位置している短冊片３２ｂと短冊片３３ｂも、埃やごみを払ったり補足する機能を発揮する。外側縁１０Ａ，２０Ａと第２の接合部８，９との間では、繊維集合体３１と短冊片３２ｂと短冊片３３ｂとが互いに独立して自由に動けるため、凹凸のある被清掃部に対しても効果的な拭き掃除を行うことができる。
【００６５】
また、清掃用物品１の拭き面３の内部に移動した埃やごみは、副清掃要素６の内側縁１０Ｂと２０Ｂにおいて、繊維集合体３１および短冊片３２ｅ，３３ｅによって捕捉される。前記短冊片３２ｅ，３３ｅは拭き面３の表面に位置しているため、主清掃要素５で捕らえることができなかったパン屑などのような比較的大きなごみを、短冊片と短冊片との間、または短冊片と繊維集合体３１との間、さらには繊維集合体３１の内部で捕捉することができる。特にこの実施の形態では、間隔Ｗａを空けた両側の幅寸法Ｗｂの範囲において、基材シート３２から切断された短冊片３２ｅと保持シート３３から切断された短冊片３３ｅとが重ねられて二重に位置し、前記幅寸法Ｗｂの両側部で、短冊片の数が多くなっている。よって清掃時にＹ方向へ移動しようとするごみを二重の短冊片３２ｅ，３３ｅで捕捉しやすくなる。
【００６６】
また、副清掃要素６は主清掃要素５に対して自由に動くことができるため、清掃用物品１を被清掃部に沿って動かしているうちに、前記パン屑などのごみやさらに大きなごみは、副清掃要素６と主清掃要素５との間のポケット部４３（図７参照）に入り込んで、落下することなく保持される。
【００６７】
したがって、清掃用物品１の拭き面３を広い範囲を埃やごみの捕集に使用することができ、埃やごみの捕集効率を高めることができる。また従来のように、外側縁１０Ａ，２０Ａの部分にのみ埃やごみが局部的に溜まることがなく、拭き面３の全域に埃やごみを分散させて捕捉できるため、長期間使用しても清掃効果が極端に低下するのを防止できる。
【００６８】
図５（Ｂ）に示すように、前記実施の形態の清掃用物品１に使用されている繊維集合体３１は、外側縁１０Ａまたは２０Ａから内側縁１０Ｂまたは２０Ｂにむけて連続して延びる繊維３１ａの集合体であり、ほぼ一定の厚みでシート状とされている。個々の繊維３１ａどうしは熱融着や接着剤により接着されていない。ただし、個々の繊維３１ａは倦縮繊維であり、この倦縮構造により繊維どうしが絡み合っている。この絡みにより繊維集合体３１はシート状態を保つことができ、且つ個々の繊維３１ａは互いに独立して比較的自由に動けるようになっている。
【００６９】
そのため、被清掃部を拭いたときに、倦縮により絡み合っている繊維と繊維の間の小さな空間が細かな埃を挟み込んだり保持するように機能でき、図２に示す主清掃要素５の拭き面３側の表面の広い範囲で、埃の捕集効果を発揮できる。
【００７０】
前記繊維集合体３１は、Ｘ方向に延びる多数の繊維３１ａを塊状にした束であるトウ（ＴＯＷ）から開繊され、さらにＹ方向に広げてほぼ均一な厚みのシート状とされたものが使用される。前記繊維３１ａはポリエチレン（ＰＥ）繊維、ポリプロピレン（ＰＰ）繊維、ポリエステル（ＰＥＴ）繊維、レーヨン繊維などである。または芯部と鞘部が共にポリエステル、芯部がポリエステルで鞘部がポリエチレン、芯部がポリプロピレンで鞘部がポリエチレンの芯鞘型の複合合成繊維などが使用される。
【００７１】
