- Each of the fixed end forces is movable portions 201 to 203 between the free ends.
- the adhesive 50 applied to the base sheet 6 penetrates between the long fibers to a predetermined depth due to its permeability.
- the length and position of the movable parts may differ greatly depending on the case in the bonding method using an adhesive. The reason will be explained.
- the application shape and area of the adhesive are arbitrary, and bonding can be performed at a plurality of scattered locations.
- the base sheet 6 and the long fiber bundle 31 are also possible to adhesively bond with a plurality of spot-like joining portions 51 that are scattered.
- the upper side in the figure is the adhesive surface with the lower surface of the base sheet 6 (not shown), and the lower side in the figure is the dust collecting surface.

- the length of the movable portion 205 of the fiber becomes approximately half of the long fiber.
- the length of the movable portion in the main cleaning portion is set in the height (vertical) direction and in-plane ( It can be discontinuously different in the (lateral) direction.
- the bundling portion has a simple line shape. Therefore, in order to make the length and position of the movable part discontinuous in the lateral direction, the following two methods must be adopted. That is, the first is a method of heating and pressing using a specially shaped press heater in which the head branches and protrudes at predetermined interspersed positions. The second is a method in which a normal press heater having a simple tip shape is used to repeat alignment and heating 'pressing for a predetermined spot location as many times as the number of joints. .

Its production method is particularly limited However, for example, two non-woven sheets may be overlapped and heat-bonded to each other by three fusion wires 63 having a predetermined interval. Alternatively, one non-woven fabric sheet may be folded back and heat-sealed to each other by three fusion wires having a predetermined interval or two fusion wires excluding the folding line. As a result, the bag-shaped gripping handle mounting portion 2 having the mounting portion base 64 on the bottom surface is made separately from the base material sheet 6. Two insertion holes 3 are formed side by side at one end of the gripping handle attaching portion 2, and the support rod 5 of the gripping handle 4 shown in FIG. 1 can be inserted into each. Also, the other end of the grip handle mounting portion 2 may be sealed by heat sealing, or may be opened so that the support rod 5 can be inserted from both sides.
- the fused wire 63 In the fused wire 63, the fibers constituting the nonwoven fabric sheet are melted together to fill the gap between the fibers, and the scattered light is suppressed from being scattered. Therefore, when the gripping handle mounting portion 2 is bonded to the base material sheet 6, when the mounting portion base 64 and the upper surface of the base material sheet 6 are bonded with the colored adhesive 50, the bonding wire 63 is bonded. The color of the agent 50 can be easily seen. As a result, the design effect of the base material sheet 6 can be more suitably obtained as compared with the case where the fused wire 63 is not provided in the grip handle attaching portion 2. Furthermore, the gripping handle 4 can be attached more easily by visually recognizing the outline of the gripping handle mounting portion 2 and thus the position of the insertion hole 3.

- the method of joining the fiber bundle and the base sheet with an adhesive as in the present invention eliminates the problem that is enormous because there is no need to apply excessive heat or pressure in the bonding process. Adhesive joining of the attachment portion 2 is also preferably performed.
- a heat-bondable long fiber and a base sheet made of non-woven cloth are joined together by a hot-melt adhesive.
- a fiber aggregate is formed by laminating spread fiber tows such as heat-sealable long fiber ridges in a planar shape.
- the substantially center part in the fiber direction is connected to each other by a heat seal along a line running in the fiber orthogonal direction to obtain a long fiber bundle.
- a hot melt adhesive is applied to one surface of the nonwoven fabric sheet at a room temperature in a spot shape over a plurality of locations. In the fourth step, this is superposed on the long fiber bundle.
- the whole is pressed by a roll heater and heated to a temperature equal to or higher than the melting temperature of the hot melt adhesive, and the long fiber bundle is impregnated with the adhesive.
- the whole is cooled to cure the hot melt adhesive, and the nonwoven fabric sheet and the long fiber bundle are fixed.
- both ends of the long-fiber bundle body in the fiber direction are fluffed to obtain a mop head-shaped cleaning tool.
- the hot blade 70 is pressed from the long-fiber bundle 31 (arrow A side in the figure) or pressed from the base sheet 6 side (arrow B side in the figure), it is pressed so as to be sandwiched from both sides. You may guess. As a result, the gap 52 is filled with an adhesive, and a predetermined adhesive strength can be imparted. [0068] In this post-processing, the temperature of the hot blade 70 is set to be equal to or higher than the melting temperature of the long fibers 31 or the base sheet 6, and the long fiber bundle 31 and the base sheet 6 are partially or partially in their thickness direction. May all be thermally fused together.
- the bonding force by heat fusion can be supplementarily added to the bonding force by the adhesive 50, and the long-fiber bundle 31 and the base sheet 6 can be bonded better.
- the pressing force for pressing the hot blade 70 is small compared to the conventional method in which the long fibers and the base sheet are joined together only by heat sealing.
- the cutting edge temperature of 70 is relatively low and the pressing time is short. Therefore, the bonded joint between the long-fiber bundle 31 and the base sheet 6 is not hardened, and no press marks remain on the upper surface of the base sheet 6, and the manufacturing efficiency of the cleaning tool is significantly reduced. Even things.
- the fiber bundle 7 and the base sheet 6 can be reliably and efficiently joined. That is, when a fiber bundle 7 made of heat-fusible fibers and a base sheet 6 made of nonwoven fabric are used, this is performed only by heat sealing as a means of joining the fiber bundle 7 to the nonwoven fabric.
- the hot blade applied to the fiber bundle 7 first heats and melts the fibers, and heat is transferred to the nonwoven fabric by, and, and the nonwoven fabric is heated and melted.
- the nonwoven fabric is a fiber entanglement body, and its surface has a rough surface, so that it is difficult to transfer heat uniformly.
- the nonwoven fabric has a void structure, heat transfer efficiency is low.
- the fiber bundle 7 is heated and melted at high speed and force so as to contact the hot blade evenly, whereas the non-woven fabric has the same material and the same fiber diameter as the fibers constituting the fiber bundle 7. However, it is difficult to efficiently heat-bond the fiber bundle 7 and the nonwoven fabric together.
- the fibers are bound to each other by any method to form a fiber bundle 7, and this is adhesively bonded to the base sheet 6. So between the fibers Even if bundling is performed by heat sealing, heat fusion between fibers can be performed efficiently in a short time. For this reason, even if the bonding process is added, the overall advantage is that the processing time can be greatly reduced compared to the conventional method in which the fiber bundle 7 and the base sheet 6 are joined together by heat sealing alone. is there.
- the bonding structure with the fibers can be made stronger. That is, when an adhesive is applied to the joint between the fiber and the nonwoven fabric, the adhesive penetrates not only into the space between the fibers but also into the fiber gap of the nonwoven fabric. In particular, since the nonwoven fabric is in a state in which short fibers are entangled, the adhesive enters a fiber gap having a complicated shape, and a large anchor effect is produced in a state where the adhesive is melted or solidified by drying. Due to this anchor effect, the bonding force between the fiber and the nonwoven fabric becomes strong.
- the cleaning tool according to the present invention has a high degree of freedom in selecting the material of the fiber base sheet, and therefore furniture such as chiffon, electrical products such as personal computers and lighting equipment, walls inside the building, sill, duck Not only domestic dust that arrives at home, but also dust that occurs in various fields, select the most suitable fiber according to the physical properties such as particle size, shape, polarity, charging property, etc. It can be carried out.
