(Configuration of cleaning body holder)
As shown in FIG. 2, the cleaning body holder 200 is mainly composed of a handle part 210 and a cleaning body holding part 220. The handle part 210 is a member that is formed in a long shape and is held by the user during cleaning. The handle part 210 has a handle 211 and a handle joint part 212. The handle joint portion 212 is joined to the connecting portion 230 of the cleaning body holding portion 220. The handle 211 is formed in a long shape extending from the handle joint portion 212. The handle portion 210 is an example of the “gripping portion” in the present invention. The cleaning body holding unit 220 is an example of the “holding unit” in the present invention.

  The cleaning body holding part 220 is a member for holding the cleaning body 100, which is molded from a resin material. The cleaning body holding part 220 is mainly composed of two holding members 221 formed in a long shape, a convex part 260, a pressing plate 270, and the like. Specifically, the cleaning body holder 220 is made of polypropylene (PP). In addition, the cleaning body holding | maintenance part 220 can select the resin material which has flexibility suitably. For example, polyethylene (PE), polyethylene terephthalate (PET), acrylonitrile-butadiene-styrene resin (ABS), and a polyester-based thermoplastic elastomer can be used.

(Configuration of cleaning body)
Next, the cleaning body 100 will be described with reference to FIGS. The cleaning body 100 is a sheet-like cleaning body having a dirt collecting function for collecting dirt such as dust to be cleaned. As shown in FIGS. 4 and 7, the cleaning body 100 is formed in a rectangular shape in plan view.
This cleaning body 100 is a disposable type that is used once as a guide, or a disposable type that is replaced with multiple uses as a guide while holding dust and dust removed from the surface to be cleaned. It may be of a type that can be used repeatedly after washing or the like.

  In the cleaning body 100, the base 120 is formed by the first sheet body 121. The base 120 has an end 120A on the longitudinal cross direction X, an end 120B on the longitudinal direction Y, one surface 120C, and the other surface 120D. The base 120, the first sheet body 121, the one surface 120C, and the other surface 120D are respectively the “base”, “first sheet body”, “one side”, and “the other side” in the present invention. It is an example.

The fiber assembly 110GF is disposed on one surface 120C of the base 120. A second sheet body 122 is disposed on the other surface 120D of the base 120.
These laminated base 120, fiber assembly 110 </ b> GF, and second sheet body 122 all extend in the longitudinal direction Y in the cleaning body 100.
The fiber aggregate 110GF forms a brush part 110 having a dirt collecting function. This fiber assembly 110GF is an example of the “fiber assembly” according to the present invention. The brush portion 110 is an example of the “brush portion” in the present invention. Note that, as in the cleaning body 100 according to this embodiment, the fiber assembly 110GF disposed on the one surface 120C side of the base 120 is referred to as a first fiber assembly 110GF1.

The fiber aggregate 110GF is formed by an aggregate of fibers 110SF. In this invention, the fiber 110SF is a single fiber structure composed of typical fibers, or a fiber structure in which typical fibers are aligned in the length direction and / or radial direction (twisted yarn, spun yarn, a plurality of long lengths). A thread material in which fibers are partially connected), or an aggregate of the fiber structure. Here, the “typical fiber” is a structural unit such as a yarn or a woven fabric, and has a length that is sufficiently long compared to the thickness, and is in a thin and flexible form. Typically, long continuous fibers are long fibers (filaments), and short fibers are short fibers (staples).
The fibers 110SF partially include thermoplastic fibers, and each fiber 110SF can be fused (also referred to as “welding”).
The fiber aggregate 110GF is formed by a plurality of fibers 110SF arranged in parallel in a predetermined fiber orientation direction 110D and stacked in the thickness direction Z. In the embodiment of the present invention, the fiber orientation direction 110D substantially coincides with the longitudinal cross direction X. On the other hand, since the fiber 110SF is a flexible material, it is easily bent and deformed. Therefore, the fiber orientation direction 110D of the fiber 110SF indicates the fiber orientation in the product design.

The fiber 110SF of the fiber assembly 110GF has a connection end portion 110SFA that is an end portion to be welded to the central joint portion 140. The fiber 110SF has an open end 110SFB that is an end opposite to the connection end 110SFA. The open end 110SFB is a free end.
The connection end 110SFA is an example of the “connection end” according to the present invention. The open end portion 110SFB is an example of the “open end portion” according to the present invention.

  In FIG. 3, the fiber assembly 110GF is formed by laminating three fiber layers, but the number of fiber layers may be one or more as necessary. The fiber assembly 110GF preferably has a surface structure of a predetermined plane or curved surface, and is configured as a three-dimensional shape having a certain thickness or a thin sheet shape. The fiber aggregate 110GF is typically made of polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), nylon, rayon, etc., and is practically a long fiber (filament) obtained by opening the tow. ) Is preferably used. In particular, the core portion is preferably made of polypropylene (PP) or polyethylene terephthalate (PET), and the sheath portion covering the outer surface of the core portion is preferably composed of a composite fiber of polyethylene (PE) to form the fiber assembly 110GF. . The fineness 110SF of the fibers forming the fiber assembly 110GF is preferably 1 to 50 dtex, more preferably 2 to 10 dtex. In addition, each fiber assembly may be composed of fibers having substantially the same fineness, or each fiber assembly may include fibers having different finenesses.

Moreover, in order to improve the dirt collection function at the time of cleaning, an oil agent is supplied to the fiber assembly 110GF. This oil agent is mainly composed of liquid paraffin.
In addition, in order to improve the sweeping function at the time of cleaning, it is preferable to use a fiber assembly 110GF including a highly rigid fiber 110SF, that is, a fiber 110SF having a high fineness. Moreover, it is preferable that the fiber assembly 110GF includes crimped fibers. A crimped fiber here is comprised as a fiber to which the well-known crimping process was provided, and is set as the structure where fibers are easy to get entangled. When such a crimped fiber is used, the fiber assembly 110GF is bulkier than the state before the cleaning body holder 200 is mounted, and a structure in which dust is easily taken into the crimped portion. This structure can be realized in particular by using crimped fibers formed from tow fibers.

The fibers 110SF of the fiber assembly 110GF constituting the brush portion 110 have the same length in the longitudinal cross direction X. Here, although it is "the same length", when a crimped fiber is used as the fiber 110GF as described above, the crimped state between the individual crimped fibers does not necessarily match. Therefore, when the lengths of the individual fibers 110SF are compared, they may not be completely the same length. Therefore, the “same length” according to the present invention merely means “same design length”.
Here, “same design length” will be described. The cleaning body 100 is formed by cutting, in a manufacturing process described later, stacked materials that are continuous in the machine direction M in two predetermined regions in a direction that intersects the machine direction M. In this case, the direction in which the two predetermined regions are cut is linear, and when they are parallel to each other, “the same design length”.
Here, the “straight line” does not necessarily indicate a “perfect straight line”. For example, even if it is curved due to design reasons or the like, it is sufficient if it is substantially “straight line”.

As shown in FIG. 7, the second sheet body 122 is a sheet formed of a rectangular nonwoven fabric shorter than the base 120 in the longitudinal direction Y.
As for the nonwoven fabric which comprises the base 120 (1st sheet body 121) and the 2nd sheet body 122, all typically the sheet-like nonwoven fabric which consists of a thermomeltable fiber (thermoplastic fiber) is used. That is, the base 120 and the second sheet body 122 are also referred to as “nonwoven fabric sheets”. 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.
In addition, synthetic fibers, such as polyethylene (PE), polypropylene (PP), and polyethylene terephthalate (PET), are used for this nonwoven fabric. Moreover, as a form of a nonwoven fabric, what was formed by the air through method or the spun bond method is used.
On the other hand, even if it is other than a nonwoven fabric, a cloth, a film body made of a synthetic resin, or the like can also be used.

The base 120 and the second sheet body 122 include a central joint 140 that extends along the longitudinal center line YCL of the cleaning body 100 and a plurality of first joints 141 that are located on both sides of the central joint 140. Are welded together. That is, as shown in FIG. 7, the base 120, the second sheet body 122, and the fiber assembly 110 </ b> GF are welded and joined at the central joint 140. Further, the base 120, the second sheet body 122, and a part of the fiber aggregate 110 </ b> GF are welded and joined at the first joint 141. In addition, the 1st junction part 141 located in the both ends side in the longitudinal direction Y is formed in the position where the 2nd sheet | seat body 122 does not exist. Therefore, the 1st junction part 141 located in the both ends in the longitudinal direction Y joins only base 120 and some fiber aggregates 110GF.
The central joint 140 is an example of the “first fiber joint” according to the present invention.

A pair of holding spaces 130 extending in the longitudinal direction Y are formed between the base 120 and the second sheet body 122 in a region sandwiched between the central joint 140 and the first joint 141. Yes. In addition, openings 131 are formed at both ends of the holding space 130 in the longitudinal direction Y, respectively. The holding space 130 is an example of the “insertion portion” in the present invention.
In other words, the holding space 130 is formed by a predetermined region of the base 120 between the pair of first joining portions 141 in the longitudinal cross direction X and a predetermined region of the second sheet body 122.

  A plurality of first joining portions 141 are formed continuously along the longitudinal direction Y. On the other hand, the first welded joints 141 adjacent in the longitudinal direction Y do not necessarily need to be arranged in the longitudinal direction Y. The arrangement form of the first welding joint portion 141 can be appropriately designed depending on the design property and the shape of the cleaning body holding portion 220. At this time, of course, the first weld joint 141 can be formed in a continuous line shape.

Furthermore, a lateral joint 140A is provided in a predetermined region between the end 120A of the base 120 in the longitudinal cross direction X and the central joint 140. In the longitudinal cross direction X, the lateral joint 140A is provided between 120A on the longitudinal cross direction X of the base 120 and the first weld joint 141. Further, in the longitudinal direction Y, the side joints 140A are provided at two positions with a gap in the direction parallel to the longitudinal direction Y. The side joint portions 140A are paired in the longitudinal cross direction X.
The side joint 140A joins the base 120, the second sheet 122, and the fiber assembly 110GF.
Note that the side joints 140A do not have to be two in the longitudinal direction Y, and may be single or plural. Further, it is not necessary to be parallel to the longitudinal direction Y.
This lateral joint 140A is an example of the “second fiber joint” according to the present invention.

The central joint 140, the first joint 141, and the side joint 140A described above are formed by welding with heat.
On the other hand, the joint portion according to the present invention can also be formed by an adhesive such as ultrasonic welding, sewing, or a hot melt adhesive.

The brush part 110 has a first brush region 111 and a second brush region 112. The second brush region 112 has a protruding region 112 </ b> L configured to be longer than the first brush region 111.
The first brush region 111 is formed of the fibers 110SF that are not joined by the side joining portion 140A in the longitudinal cross direction X.
The second brush region 112 is formed of fibers joined in the longitudinal cross direction X by the side joining portion 140A.

The second brush region 112 is formed longer than the first brush region 111. Here, “long” will be described with reference to FIG.
In the longitudinal cross direction X, the longest straight line among the straight lines connecting the longitudinal center line YCL and the end portion 111B in the longitudinal cross direction X in the first brush region 111 is defined as a first brush region length 111D.
In the longitudinal cross direction X, the longest straight line among the straight lines connecting the longitudinal center line YCL and the end portion 112B on the longitudinal cross direction X in the second brush region 112 is defined as a second brush region length 112D.
The second brush region 112 being longer than the first brush region 111 means that the second brush region length 112D is longer than the first brush region length 111D.
In addition, the 2nd brush area | region 112 which is an area | region longer than the 1st brush area | region 111 comprises 112 L of protrusion areas.

In the cleaning body 100 according to the present invention, the fiber 110SF is flexible. Therefore, when used by the user, the shape of the fiber 110SF changes. As a result, there may be a case where the relationship that the second brush region length 112D is longer than the first brush region length 111D is not established.
When the user uses the cleaning tool A, the protruding region 112L exhibits a predetermined action and effect. Therefore, the relationship between the first fiber length 111D and the second fiber length 112 described above is determined immediately after the cleaning body 100 is manufactured, immediately after the user purchases the product and takes out the cleaning body 100, or the user. However, when the cleaning body 100 is used, it is sufficient to form it immediately after the cleaning body 100 itself is greatly swung to increase the distance between the fibers 110SF to make it bulky.

In the cleaning body 100 according to the embodiment of the present invention, the first brush region 111 is provided at the end portion 100B in the longitudinal direction Y. Moreover, the 1st brush area | region 111 and the 2nd brush area | region 112 are arrange | positioned alternately.
On the other hand, the second brush region 112 may be provided at the end portion 100B in the longitudinal direction Y, and the first brush region 111 and the second brush region 112 are formed one by one. The configuration may be different.

The brush part 110 has a contact area 160 that contacts the cleaning target. Based on FIG. 6, the contact area 160 will be described.
The contact area 160 includes a first contact area 161, a second contact area 162, and a third contact area 163. The first contact region 161 is formed in the first brush region 111. The second contact region 162 is formed between the central joint 140 and the side joint 140A in the second brush region 112. The third brush region 163 is formed between the side joint 140A and the open end portion 110SFB in the second brush region 112.
The contact area 160 is an example of the “contact area” according to the present invention. The first contact area 161 is an example of the “first contact area” according to the present invention. The second contact area 162 is an example of the “second contact area” according to the present invention. This third contact area is an example of the “third contact area” according to the present invention.

The second contact region 162 has a lower region 162A formed lower than the first contact region 161 in the thickness direction Z. The lower region 162 </ b> A is a guide region 162 </ b> B that can guide the dust to be cleaned to the adjacent first contact region 161.
The lower region 162A and the guide region 162B are formed as a region including the side joint 140A that is a boundary between the second contact region 162 and the third contact region 163. Therefore, it can be said that the lower region 162A and the guide region 162B are formed in the third contact region 163. It can also be said that the lower region 162A and the guide region 162B are formed between the second contact region 162 and the third contact region 163.
Hereinafter, for the sake of convenience, the lower region 162A and the guide region 162B will be mainly described as being provided in the second contact region 162.

The fact that the lower region 162A is formed “lower” in the thickness direction Z than the first contact region 161 in the second contact region 162 will be described.
140 A of side junction parts have contact | abutting opposing area | region 140A1 which is an area | region facing the contact area | region 160, and contact | abutting side area | region 140A2 which is an area | region of the contact | abutting area | region 160 side. The shortest length in the thickness direction Z between the contact facing region 140A1 and the contact region 140A2 is defined as a second contact region height 162Z.
Next, a point on the contact facing area 140A1 of the side joint 140 at the point where the second contact area height 162Z is obtained is set as a height measurement point 140A1P. A straight line passing through the height measurement point 140A1P and parallel to the longitudinal direction Y is defined as a height measurement straight line 161Y. Among the lengths in the thickness direction Z between the height measurement straight line and the first contact region 161, the longest length is defined as a first contact region height 161Z.
That is, in the thickness direction Z, the second contact region 162 is “lower” than the first contact region 161. The second contact region height 162 Z is the first contact region height. It means “shorter” than 161Z.

In the cleaning body 100 according to the present invention, the fiber 110SF is flexible. Therefore, when used by the user, the shape of the fiber 110SF changes. As a result, there may be a case where the second contact area height 162Z does not establish a relationship of “shorter” than the first contact area height 161Z.
The lower region 162A exhibits a predetermined action and effect when the user uses the cleaning tool A. Therefore, the relationship between the first contact area height 161Z and the second contact area height 162Z described above is that immediately after the cleaning body 100 is manufactured or the user purchases the product and takes out the cleaning body 100. Immediately after the user uses the cleaning body 100, the cleaning body 100 itself is greatly shaken to increase the distance between the fibers 110SF to make it bulky.

  Accordingly, the lower region A162 is a region including the contact side region 140A2 of the side joint 140A. Furthermore, the guidance region 162B is a region parallel to the longitudinal direction Y in the lower region 162A. When the guide region 162B is extended, the guide region 162B comes into contact with the side portion of the first contact region 161. Therefore, the dust to be cleaned that has passed through the guidance area 162B is easily captured by the side area 161A of the first contact area 161.

  Both ends of the fiber 110SF forming the second contact region 162 are fixed by the center joint 140 and the side joint 140A. Therefore, the fiber 110SF constituting the second contact region 162 has a narrower movable width than the fiber 110SF forming the first contact region 161 and the fiber 110SF forming the third contact region 163. Is. Therefore, when the user uses the cleaning tool A, for example, resistance can be applied to dust that is strongly adhered to the object to be cleaned. Therefore, the second contact region 162 is a resistance region 162C that can apply resistance to the dust to be cleaned. This resistance region 162C is an example of the “resistance region” according to the present invention.

The cleaning body 110 has a strip piece 150. The strip 150 is formed on the longitudinal crossing method X on the first strip 151 formed between a plurality of cut lines provided at the end of the base 120 in the longitudinal crossing direction X and the second sheet body 122. And a second strip piece 152 formed between a plurality of cut lines provided at the end of the second strip piece 152. Note that the cut lines in the base 120 and the second sheet body 122 have a zigzag shape. By making the strips 150 into a zigzag shape, a structure with a high cleaning function that can easily catch and capture dust is realized. In addition, regarding the shape of the strip, a single type or a plurality of types of shapes such as a zigzag shape, a linear shape, and a curved shape can be appropriately used.
The strip 150 may be either the first strip 151 or the second strip 152.

(Engagement of cleaning body holder and cleaning body)
Next, the engagement between the cleaning body holder 200 and the cleaning body 100 will be described with reference to FIGS. 9 and 10. As shown in FIG. 9, each holding member 221 can be inserted into the holding space 130. The cleaning body 100 is held by the cleaning body holder 200 by the holding member 221 being inserted into the holding space 130 along the insertion direction Y1. On the other hand, in order to separate the cleaning body holder 200 and the cleaning body 100 engaged with each other, the cleaning body holder 200 is pulled out from the holding space 130 along the pulling direction Y2.

In the engaged state of the cleaning body holder 200 and the cleaning body 100, the convex portion 260 is disposed between the adjacent first joint portions 141. Thereby, the engagement state of the cleaning body holder 200 and the cleaning body 100 is reliably maintained.
In addition, the holding plate 270 holds the second sheet body 122 together with the holding member 221.

(Function)
Next, the operation of the cleaning tool A according to the embodiment of the present invention will be described. When cleaning is performed using the end portion 100A on the longitudinal cross direction X of the cleaning body 100, the protruding region 112L of the second brush region 112 is brought into contact with the object to be cleaned. Then, the cleaning body 100 can be moved in a direction substantially along the longitudinal direction Y. Thereby, it becomes possible to scrape dust to be cleaned.
When a plurality of protruding regions L are formed, the plurality of protruding regions 112L can be continuously brought into contact with the object to be cleaned. Therefore, it is possible to further improve the cleaning effect.

Next, based on FIG. 11, a case where the cleaning operation is performed by pressing the contact area 160 widely will be described. For example, when cleaning the floor F or the like, the user holds the handle 211 and presses the cleaning area 160 of the cleaning body 100 against the floor F. Then, the user moves the cleaning body 100 on the floor F. At this time, for example, it is assumed that dust that could not be captured on the surface of the first contact region 161 was generated. In this case, the dust that has not been captured in the first contact region 161 is transferred to the guide region 162B of the lower region 162A by the user's cleaning operation. Then, the dust transferred to the guidance area 162B is captured in the second contact area 162 or the third contact area 163. Here, dust that has not been captured in the second contact region 162 or the third contact region is captured in the side region 161A of the first contact region 161.
In addition, since the fiber 110SG is flexible, when the cleaning body 100 is pressed against the floor F with a strong pressure, the lower region 162A and the guide region 162B may be crushed. On the other hand, when the cleaning tool A is used within the range in which the lower region 162A and the guide region 162 are formed, the present invention is configured as long as dust can be captured.

  Further, for example, dust that adheres to the floor F and cannot be captured by the “pay” operation in a normal cleaning operation is assumed. In such a case, the user presses the resistance region 162C against the attached dust and performs a cleaning operation. As a result, the dust is separated from the floor F by the fibers 110SF having a small movable region in the resistance region 162.

  That is, in the cleaning tool A according to the present invention, the protruding area L can improve the dust scraping operation. Further, the lower region 162A and the guiding region 162B can increase the chance that dust is captured by the fiber assembly 110GF. Moreover, the dust attached to the cleaning target can be separated from the cleaning target by the resistance region 162C.

(Manufacturing process)
Next, in FIGS. 12-20, the manufacturing method of the cleaning tool A of embodiment which concerns on this invention is demonstrated. First, before describing the specific manufacturing process, the fiber 110SF forming the fiber assembly 110GF according to the present invention will be described.
FIG. 12 shows a fiber 110SF that forms the fiber assembly 110. The fiber 110SF according to FIG. 12 shows a stationary state where no external force is applied. Since the fiber 110SF is a crimped fiber, it has a plurality of bent portions 110SFC and has a zigzag shape. The bent portion 110SFC is also called a crimp portion.
The fiber 110SF can be expanded and contracted by having the bent portion 110SFC. FIG. 13 shows a state in which an external force (tension) is applied in opposite directions to both ends of the stationary fiber 110SF. Thus, the fibers 110SF can be extended by separating the distance between the bent portions 110SF. On the other hand, in the state where the external force is released, the fiber 110SF returns from the extended state shown in FIG. 13 to the stationary state shown in FIG.

Here, the base 120 and the fiber assembly 110GF have different elastic elastic modulus. That is, the stretch elastic modulus of the fiber assembly 110GF is higher than the stretch elastic modulus of the base 120. Specifically, the stretch elastic modulus of the fiber assembly 110GF is 75.7%, and the stretch elastic modulus of the base 120 is 56.0%.
In addition, in the measurement of elastic modulus of elasticity, it carried out by the following test.
(1) A test piece of the fiber assembly 110GF and a test piece of the base 120 are prepared. The test piece has a length of 500 mm.
The fiber assembly 110GF used was a tow fiber formed of a core-sheath composite fiber in which polyethylene (PE) is a sheath material and polyethylene terephthalate (PET) is a core material. This tow fiber has a fineness of 3.5 dtex for one fiber. The fineness of the entire fiber assembly is 110,000 dtex.
The base 120 is a spunbonded nonwoven fabric formed of a core-sheath composite fiber in which polyethylene (PE) is a sheath material and polyethylene terephthalate (PET) is a core material. This nonwoven fabric has a basis weight of 20 g / m2. The width was 190 mm.
(2) A mark indicating the start and end of a predetermined length is attached in the longitudinal direction of the test piece. This mark indicates a length of 200 mm. The length between the start end and the end end in this state is L0. L0 is 200 mm.
(2) Fix the upper end of the test piece with a clip.
(3) A 5 kg weight is suspended so that a load is applied to the entire width at the lower end of the test piece.
(4) After 30 seconds have elapsed, the length between the start end and the end attached to the test piece is measured. This length is L1.
(5) After the elapse of 30 seconds except for the weight, the length between the start end and the end attached to the test piece is measured. This length is L2.
(6) A value obtained by dividing the difference between L1 and L2 by the difference between L1 and L0 and further multiplying by 100 was taken as the elastic modulus of elasticity.
(7) This test was performed 5 times to obtain an average numerical value.

And the sixth step S16.
In addition, the cleaning body 100 which concerns on embodiment of this invention has the strip piece 150. FIG. On the other hand, for the convenience of explanation, it is omitted in the manufacturing process of the strip piece 150.

FIG. 15 shows the first step S11. In the first step S11, a first sheet material 1211 for forming the first sheet body 121 to be the base 120, a second sheet material 1221 for forming the second sheet body 122, A first fiber assembly material 110GF1A for forming a part of one fiber assembly 110GF1 is supplied. As a result, the first fiber aggregate material 110GF1A is disposed on one side of the first sheet material 1211. The second sheet material 1221 is disposed on the other side of the first sheet material 121.

  FIG. 16 shows the second step S12. In the second step S12, all layers of the second sheet material 1221, the first sheet material 1211, and the first fiber assembly material 110GF1 are welded. At this time, two portions of the predetermined region in the second sheet material 1221, the first sheet material 1211, and the first fiber assembly material 110GF1 are welded. The welded portions form a pair of first joint portions 141.

FIG. 17 shows the third step S13. In the third step S13, the second fiber assembly material 110GF1B is supplied. The second fiber assembly material 110GF1B is supplied to the side of the first fiber assembly material 110GF1A where the first sheet material 1211 is not disposed.
Note that the fiber orientation direction 110D of the second fiber assembly material 110GF1B approximately matches the machine direction M.

FIG. 18 shows a fourth step S14. In the fourth step S14, all layers of the second sheet material 1221, the first sheet material 1211, the first fiber assembly material 110GF1A, and the second fiber assembly material 110GF1B are joined by thermal welding. . By this joining operation, a central joint 140 and a side joint 140A are formed.
In forming the central joint 140, all of the predetermined regions that cross the fiber orientation direction 110D in the first fiber assembly 110GF1 are joined.
In the formation of the side joint 140A, a part of a predetermined region crossing the fiber orientation direction 110D in the first fiber assembly 110GF1 is joined. Specifically, the lateral joint 140A is welded at two locations in a direction crossing the fiber orientation direction 110D.

The central joint 140 and the side joint 140A can be provided by a single joining device. In this case, the center joint 140 and the side joint 140A are formed almost simultaneously.
On the other hand, the joining device that forms the central joint 140 and the joining device that joins the side joint 140A may be independent joint devices. In this case, the side joint 140A can be provided after the central joint 140 is provided. On the other hand, the central joint 140 can be provided after the side joint 140A is provided.

Note that a predetermined tension is applied to the first fiber assembly material 110GF1A over the first step S11 to the fourth step S14. A specific tension is 40N.
It should be noted that the predetermined tension applied to the first fiber assembly material 110GF1A and the second fiber assembly material 110GF1B is applied to stabilize the shape for easy manufacture.
Further, this tension is applied to shrink the fibers 110SF of the fiber assembly material 110GF and form the first brush region 111 and the second brush region 112 in the manufacturing process described later.
Note that tension is also applied to the first sheet material 1211 and the second sheet material 1221 in order to stabilize the shape.

In the fifth step S15, the second sheet material 1221, the first sheet material 1211, the first fiber assembly material 110GF1A, and the second fiber assembly material 110GF1B are cut at predetermined regions. By this cutting operation, the second sheet material 1221, the first sheet material 1211, the first fiber aggregate material 110GF1A, and the second fiber aggregate material 110GF1B are released from the tension.

FIG. 20 shows a sixth step S16. In the sixth step S16, the fiber 110SF corresponding to the first fiber assembly material 110GF1A released from the tension contracts toward the inner direction 100D2 in the longitudinal cross direction X.
The fibers connected to both the central joint 140 and the side joint 140A are also connected to the first sheet body 121 and the second sheet body 122. Therefore, the contraction of the fiber 110SF is limited by the first sheet body 121 and the second sheet body 122.
On the other hand, the fiber 110SF joined only to the central joint 140 contracts significantly compared to the fiber 110SF connected to the first sheet body 121 and the second sheet body 122.
