The fiber bundles 3a and 3b have the same flow direction of the fibers constituting the fiber bundles 3a and 3b. The cleaning sheet 1 joins the fiber bundle 3a and the support sheet 2 so as to cross the flow direction of the fibers constituting the fiber bundle 3, thereby forming a joint 5 (5a). As with the fiber bundle 3a, the cleaning sheet 1 joins the fiber bundle 3b and the support sheet 2 to form a joint 5 (5b). Ends 31 a and 31 b in the fiber flow direction of the fiber bundle 3 are not joined to the support sheet 2 and are free ends. The joint portion 5 is formed in a narrow strip shape extending continuously in the center of the support sheet 2. The width | variety of the junction part 5 can be set suitably. In addition to the strip shape, the joint portion 5 may be formed in a straight line shape, a curved line shape, a broken line shape, or an intermittent dot shape as long as the fiber bundle 3 can be joined to the support sheet 2.
（支持体シート２）
　支持体シート２は、複数のシート材としての複数の基材シート６（６ａ，６ｂ）を積層するとともに、基材シート６ａ，６ｂを互いに接合して基材接合部６０を形成している。 (Support sheet 2)
The support sheet 2 is formed by laminating a plurality of base material sheets 6 (6a, 6b) as a plurality of sheet materials and joining the base material sheets 6a, 6b to each other to form a base material joining portion 60.
　基材接合部６０は、点状に形成された接合要素６０ａが接合部５から所定間隔を隔てて接合部５の長手方向に沿って断続的に複数個形成されて点列をなして、すなわち点列群をなして、形成されている。このような点列群は、接合部５を挟んで両側（基材シート６の面外方向両側）に形成される。基材接合部６０が形成されることにより、基材シート６ａと基材シート６ｂの間には空間部が形成されている。この空間部は、後述の保持部材９を挿入可能な柄挿入部６１をなす空間である。すなわち、柄挿入部６１をなす空間部は、外部と連通するとともに保持部材９を挿入可能な大きさに開口し、その開口した部分から奥方に向かって保持部材９を挿入可能に広がる空間を備える。保持部材の形状に応じて柄挿入部６１をなす空間部が、筒状、矩形袋状、舌片状などの適宜形状に定められ、その空間部の形状と基材シート６ａ，６ｂの形状に応じて、基材接合部６０をなす点列群の形状や配置が定められ、支持体シート２に個々の接合要素６０ａを形成するべき部分が適宜定められる。なお、接合要素６０ａは、基材シート６ａ，６ｂを互いに接合できて柄挿入部６１を形成できるのであれば、上記したような点状のほか、円状、楕円状、多角形状の適宜形状に形成されてよい。また、基材接合部６０は、接合要素６０ａから形成されなくとも、帯状、直線状、曲線状等適宜形状に形成されてよい。この場合には、支持体シート２において基材接合部６０は点列群を形成せずに柄挿入部６１が形成される。 In the base material joint portion 60, a plurality of joint elements 60a formed in a dot shape are intermittently formed along the longitudinal direction of the joint portion 5 at a predetermined interval from the joint portion 5 to form a dot sequence, that is, It is formed as a point sequence group. Such point sequence groups are formed on both sides (both sides in the out-of-plane direction of the base sheet 6) with the joint portion 5 interposed therebetween. By forming the base material bonding portion 60, a space is formed between the base material sheet 6a and the base material sheet 6b.

The cleaning sheet 1 is further formed with a spot joint 13 that partially joins the fibers of the fiber bundle 3 to the support sheet 2, and the fiber bundle 3 and the support at the joint 5 and the spot joint 13. The sheet 2 may be joined (FIG. 5). The dotted joint 13 is formed by joining the fiber bundle 3 and the support sheet 2 in a dotted manner at a predetermined position (scheduled joint position) from the joint 5 to the tip 31 of the fiber bundle 3.

The laminated body C which overlaps in order of 6b and the fiber bundle 3b is formed. A predetermined spot joining position is defined on the surface of the laminate C, and a joining method using a thermal fusion method or ultrasonic welding is applied to the spot joining planned position to form a large number of spot joining parts 13. At this time, each dotted joint portion 13 is a portion where the fiber bundle 3a, the base sheet 6a, the base sheet 6b, and the fiber bundle 3b are welded and integrated at the spot joint planned position. Thus, simultaneously with the formation of the dot-like joint portion 13, the base material sheets 6a and 6b are joined, and the support sheet 2 is formed. In this case, the spot-like joining planned position is appropriately determined according to the shape of the handle insertion portion 61, and the handle insertion portion 61 is a space between the base material sheets 6a and 6b, and the spot-like joining is performed. It is formed as a space part surrounded by the group of parts 13.

The dust can be removed more effectively.

Regarding the size of the porous piece 4, first, the length (width) and thickness in the short direction of the porous piece 4 can be set as appropriate. However, the porous piece 4 is formed on the fibers constituting the fiber bundle 3 at the time of cleaning.

It may be joined directly to the surface of the material sheet 6 (FIGS. 3B and 3C). For example, the fiber bundle 3 is partially laminated on the base material sheet 6 surface of the support sheet 2 to form the fiber bundle lamination portion 20 and the fiber bundle non-lamination portion 21 on the same surface of the base material sheet 6. The porous piece 4 may be joined to the fiber bundle non-laminated portion 21.

　清掃具５０は、清掃シート１が脱落しないように保持部材９にて保持されており、片手持ち運び清掃可能な清掃具（ハンディモップ）として好ましく使用できるものである。この清掃具５０によれば、把持部１０を手で持たれて清掃シート１の繊維束３が被清掃面に当接されることで、繊維束３にて被清掃面の塵や埃が取り除かれる。そして、被清掃面にこびりついて繊維束３では絡めとれなかった塵や埃については、清掃者が清掃シート１の多孔質片４を塵や埃に押し当てながら清掃具５０を動かすことで、弾力性を有する多孔質片４により被清掃面にこびりついた塵や埃を取り除くことができる。すなわち、清掃時に清掃シート１が被清掃面に押し付けられた際、多孔質片４が被清掃面にこびりついた塵や埃に適度な圧力で弾力的に接触することとなる。このとき塵や埃が多孔質片４との間の摩擦などにより被清掃面から離れやすくなって被清掃面から多孔質片４に移り、被清掃面から塵や埃が拭い取られる。さらに、被清掃面から容易に離れる状態となるものの被清掃面から多孔質片４に移りきらなかった塵や埃については、清掃シート１において多孔質片４と同一面上にある繊維束３にて効果的に絡めとられる。なお、清掃シート１の多孔質片４は適度の弾性力を有するので、清掃時に清掃具５０の清掃シート１によって被清掃面が傷つけられる虞は、効果的に抑えられている。 The cleaning tool 50 is held by the holding member 9 so that the cleaning sheet 1 does not fall off, and can be preferably used as a cleaning tool (handy mop) that can be carried by one hand and cleaned. According to the cleaning tool 50, dust and dirt on the surface to be cleaned are removed by the fiber bundle 3 by holding the grip portion 10 by hand and the fiber bundle 3 of the cleaning sheet 1 being in contact with the surface to be cleaned. It is. The dust that has stuck to the surface to be cleaned and cannot be entangled by the fiber bundle 3 is moved by the cleaner moving the cleaning tool 50 while pressing the porous piece 4 of the cleaning sheet 1 against the dust or dust. The porous piece 4 having the property can remove dust and dirt stuck to the surface to be cleaned. That is, when the cleaning sheet 1 is pressed against the surface to be cleaned at the time of cleaning, the porous piece 4 is elastically brought into contact with dust or dust stuck to the surface to be cleaned with an appropriate pressure. At this time, the dust is easily separated from the surface to be cleaned due to friction between the porous piece 4 and the like, and moves from the surface to be cleaned to the porous piece 4 so that the dust and dust are wiped from the surface to be cleaned. Furthermore, although it is easily separated from the surface to be cleaned, dust and dust that have not been transferred from the surface to be cleaned to the porous piece 4 are collected in the fiber bundle 3 on the same surface as the porous piece 4 in the cleaning sheet 1. Effectively entangled. In addition, since the porous piece 4 of the cleaning sheet 1 has an appropriate elastic force, the possibility that the surface to be cleaned is damaged by the cleaning sheet 1 of the cleaning tool 50 during cleaning is effectively suppressed.
　また、本発明によれば、多孔質片４が適度な反発力と弾性力を有するため、清掃時に、サッシレールの溝や、壁の溝部、電話・パソコンのキーボード等の溝部といった溝部分に容易に多孔質片４を入りませることができ、そうした溝部分に付着した塵を多孔質片４によって効果的に取り除かせることができるようになる。 Further, according to the present invention, since the porous piece 4 has an appropriate repulsive force and elastic force, it is easy to clean a groove portion such as a sash rail groove, a wall groove portion, a groove portion of a telephone / PC keyboard, etc. during cleaning. The porous piece 4 can be allowed to enter, and dust adhering to the groove portion can be effectively removed by the porous piece 4.
　なお、清掃シート１が清掃具５０に取り付けられて清掃に使用される際には、予め繊維束３にエアーを吹き付ける処理などが清掃シート１に施されることによって、繊維束３が開繊されて、繊維束３が嵩高で柔らかな綿塊様の状態とされていることが好ましい。 In addition, when the cleaning sheet 1 is attached to the cleaning tool 50 and used for cleaning, the fiber bundle 3 is opened by performing a process of blowing air on the fiber bundle 3 in advance. Thus, it is preferable that the fiber bundle 3 is in a bulky and soft cotton lump-like state.
　本発明は、塵や埃を除去するための清掃シートとして家庭などで用いるのに有益である。 The present invention is useful for use at home as a cleaning sheet for removing dust and dirt.
