As this nonwoven fabric, those manufactured by air-through method, spun bond method, thermal bond method, spun lace method, point bond method, melt blow method, stitch bond method, chemical bond method, needle punch method, etc. should be used as appropriate. Can do. The nonwoven fabric referred to here corresponds to the “nonwoven fabric” in the present invention. In addition, in order to improve the sweeping-out function at the time of cleaning, it is preferable to use a highly rigid nonwoven fabric. Instead of or in addition to the non-woven fabric, a material obtained by processing a material such as urethane, sponge, woven fabric, net, or walif into a strip shape may be used.

(Composition of fiber bundle)
On the other hand, each of the fiber bundles 133 and 152 is a single fiber structure made of fibers or a fiber structure in which fibers are aligned in the length direction and / or radial direction (twisted yarn, spun yarn, and a plurality of long fibers are partially Or the like, or an aggregate of the fibrous structure, and is configured as a fiber body that includes thermoplastic fibers in part and can be joined. The fiber forming each fibrous body is a structural unit such as a thread or a woven fabric, and is defined as a thin and flexible form having a sufficient length compared to the thickness, and typically a long continuous The shaped fibers are long fibers (filaments), and the short fibers are short fibers (staples). The fiber is configured to extend in a long shape in the first direction 10. The fiber bundles 133 and 152 preferably have a planar structure with a predetermined plane or curved surface, and are configured as a three-dimensional shape having a certain thickness or a thin sheet shape. Typically, PE, PP, PET, nylon, rayon or the like is used as a material, and in practice, a collection of long fibers (filaments) obtained by opening the tow is often used as the fiber bundles 133, 152. . This long fiber preferably has a fineness of 0.5 to 66 dtex. Moreover, when using the fiber containing a thermoplastic resin, it is preferable to use at least 2 or more types of resin of different melting | fusing point (For example, resin whose melting | fusing point difference is 20 degreeC or more).

  Moreover, in order to improve the sweep-out function at the time of cleaning, it is preferable to use a fiber bundle containing fibers having high rigidity, that is, fibers having high fineness. The fiber bundle is preferably configured to have crimped fibers. In this case, it is preferable to use crimped fibers having 5 to 30 crimps per inch. A crimped fiber here is comprised as a fiber to which the predetermined winding shrinkage process was provided, and is set as the structure where fibers are easy to get entangled. When such a crimped fiber is used, the fibrous body becomes bulkier than the state before the holder is mounted, and a structure in which dust is easily taken into the crimped portion is obtained. This structure can be realized in particular by using crimped fibers formed from tow fibers. Moreover, it is preferable to use a fiber containing a dusting oil agent in order to reliably adsorb dust, dust, dust and the like.

  According to the cleaning tool 111 having the above-described configuration, the holding unit 121 and the brush unit 141 are joined to each other, and the brush unit 141 is peeled from the holding unit 121 and held in the first cleaning mode in which the brush unit 141 forms the main cleaning unit. At least two cleaning modes of the second cleaning mode in which the part 121 forms the main cleaning part can be performed. That is, in the first cleaning mode, the brush portion 141 of the cleaning tool 111 forms a capturing region that substantially captures dust and dirt, while in the second cleaning mode, the holding portion 121 of the cleaning tool 111 is A trapping region for trapping dust and dust is formed substantially.

  In the first cleaning mode, the brush portion 141 is disassembled with the plurality of fibers of the fiber bundle 152 having the first joint portion 155 as a fixed end and the tip in the first direction 10 as a free end, and the sheet thickness direction (third The direction 30) is bulky. Then, dust and dirt are captured by the first sheet 151 of the brush portion 141 and the fiber bundle 152 in the vicinity thereof by the cleaning operation of the cleaning tool 111. If the brush part 141 becomes dirty with this cleaning operation, the user can peel the brush part 141 from the holding part 121 by pulling the brush part 141 at an arbitrary timing. Thereby, the fiber bundle 133 of the holding part 121 can be exposed in the second cleaning mode, and the fiber bundle 133 of the holding part 121 that is difficult to use with the conventional cleaning tool can be effectively used for cleaning. It is. Further, it is possible to give the user a sense of fulfillment that the cleaning tool 111 has been used up.

  On the other hand, in the second cleaning mode, the holding unit 121 is disassembled with the plurality of fibers of the fiber bundle 133 having the second joints 136 and 137 as fixed ends and the front end in the first direction 10 as a free end. It is in a bulky state with respect to the direction (third direction 30). Then, dust and dirt are captured by the fiber bundle 133 of the holding unit 121 by the cleaning operation of the cleaning tool 111. At this time, since the entire thickness of the cleaning tool 111 in the third direction 30 is reduced by peeling the brush portion 141, it can be effectively used for cleaning a narrow space such as a gap or cleaning the floor surface. it can.

  The tensile load related to the adhesive 161 is preferably set to 2 to 10 [N], and more preferably set to 5 to 10 [N]. By setting the tensile load to exceed 2 [N], the brush portion 141 can be prevented from peeling from the holding portion 121 during the cleaning operation in the first cleaning mode, while the tensile load is less than 10 [N]. Depending on the setting, the user does not feel that the brush portion 141 is difficult to peel from the holding portion 121 or cannot be peeled off.

  Further, regarding the bonding structure of the holding part 121 and the brush part 141, it is preferable that the adhesive force between the brush part 141 and the adhesive 161 exceeds the adhesive force between the holding part 121 and the adhesive 161. Thereby, when the brush portion 141 is peeled from the holding portion 121, more adhesive 161 remains on the brush portion 141 side, and the cleaning operation by the holding portion 121 is facilitated in the subsequent second cleaning mode. With the peeling operation, the fiber bundle 133 of the holding part 121 is easily raised as it is, and it is reasonable that the operator does not need to perform an operation of raising the fiber bundle 133 and raising the volume during the cleaning operation.

  In relation to the cleaning tool 111 having the above-described configuration, the configurations of the holding unit 121 and the brush unit 141 can be appropriately changed. 12 to 15 are referred to for the modification example. 12 to 15, the same components as those in FIGS. 2 and 3 are denoted by the same reference numerals, and the description of the same components is omitted.

In the cleaning tool 113, the holding part 123 is configured differently from the holding part 121 of the cleaning tool 111, and the brush part 143 has the same configuration as the brush part 141 of the cleaning tool 111. The holding part 123 further includes a fiber bundle 134 similar to the fiber bundle 133 in addition to the holding part 121 of the cleaning tool 111. Then, a single fiber bundle 133 is stacked on the sheet surface of the two layers of the first sheet 131 and the second sheet 132 on the second sheet 132 side, and one layer of fibers is further stacked on the sheet surface on the first sheet 131 side. In a state where the bundle 134 is overlapped, these four-layer components are welded to each other by the first joint 135 and the pair of second joints 136 and 137. One brush portion 143 is bonded to the fiber bundle 133 of the holding portion 123 via an adhesive 161, and the other brush portion 143 is bonded to the fiber bundle 134 of the holding portion 123 via another adhesive 162. Has been. In this case, the adhesives 161 and 162 have an adhesive force capable of peeling the pair of brush portions 143 from the holding portion 123 by the user's tensile load. The adhesive 162 only needs to realize a desired peeling performance, and may be the same adhesive as the adhesive 161 or may be the same kind or different kind of adhesive as the adhesive 161. The adhesive 162 here corresponds to the “second adhesive” in the present invention. Further, the one brush portion 143 here corresponds to the “first cleaning body” in the present invention, and the other brush portion 143 corresponds to the “third cleaning body” in the present invention, and the holding portion 123.
