Description

本発明は、家庭や工場、病院、店舗等の様々な場所において、床や壁等の表面に付着した塵や埃等の拭き取り清掃に用いることのできる清掃用シートに関する。 The present invention relates to a cleaning sheet that can be used for wiping and cleaning dust and dirt adhering to surfaces such as floors and walls in various places such as homes, factories, hospitals, and stores.

床に落ちたパンの粉等の食品の屑、髪の毛、綿埃、壁に付着した埃等を除去するために、従来は箒やモップ、布雑巾等の清掃具が用いられていたが、近年、柄の付いた台座に不織布等からなる清掃用シートを取付け、シートが汚れたら取り外して新しいシートと交換して使用することができる清掃具が広く用いられるようになってきた。この種の清掃具に用いられる清掃用シートとして、近年、不織布等の基材シートと繊維シートとからなるものが用いられており、この種の清掃用シートとして、長繊維の配向方向と交差する方向に直線状に延びる複数の繊維接合部により接合した繊維シートを、繊維接合部の一部に重なるようにシート接合部を設けて基材シートと接合し、長繊維束を複数の線状カット部でカットして刷毛部を形成したものが知られている（特許文献１）。 In order to remove food waste such as bread powder that fell on the floor, hair, cotton dust, dust attached to the wall, etc., cleaning tools such as bags, mops, cloth cloths etc. have been used in the past. A cleaning tool that can be used by attaching a cleaning sheet made of nonwoven fabric or the like to a pedestal with a handle, and removing the sheet when it becomes dirty and replacing it with a new sheet has come to be widely used. In recent years, as a cleaning sheet used in this type of cleaning tool, a sheet made of a base sheet such as a nonwoven fabric and a fiber sheet has been used, and this type of cleaning sheet intersects the orientation direction of long fibers. A fiber sheet joined by a plurality of fiber joints extending linearly in the direction is joined to a base sheet by providing a sheet joint so as to overlap a part of the fiber joint, and a long fiber bundle is cut into a plurality of linear shapes The thing which cut by the part and formed the brush part is known (patent document 1).

上記特許文献１に記載されている清掃用シートは、繊維束と基材シートとを接合するシート接合部が、長繊維の配向方向と交差する方向に直線状に延びる繊維接合部の一部に重なるように設けられているため、線状カット部によって繊維を切断して形成した刷毛部における繊維の自由度が十分ではなく、特に隣接する刷毛部間では細かい埃や塵を確実に捕集除去し難かった。またヒートシールによって繊維接合部と一部に重なるようにシート接合部を設ける特許文献１記載の清掃用シートは、繊維束と基材シートとの接合に多くの熱エネルギーが必要となり、シール時間が長くかかるため生産効率が十分でないという問題があった。本発明は上記従来の問題を解決した清掃用シートを提供することを目的とする。 In the cleaning sheet described in Patent Document 1, the sheet bonding portion that bonds the fiber bundle and the base sheet is part of the fiber bonding portion that extends linearly in a direction that intersects the orientation direction of the long fibers. Since it is provided so that it overlaps, the degree of freedom of the fibers in the brush part formed by cutting the fibers with the linear cut part is not sufficient, and especially dust and dust are reliably collected and removed between adjacent brush parts It was difficult. In addition, the cleaning sheet described in Patent Document 1 in which the sheet bonding portion is provided so as to partially overlap the fiber bonding portion by heat sealing requires a large amount of heat energy for bonding the fiber bundle and the base sheet, and the sealing time is long. There was a problem that the production efficiency was not sufficient because it took a long time. It is an object of the present invention to provide a cleaning sheet that solves the above-described conventional problems.
