Hereinafter, the cleaning article of the present invention will be described based on a first embodiment which is a preferred embodiment thereof with reference to the drawings.
As shown in FIGS. 1 to 4, the cleaning article 10 of the present embodiment is vertically long and has a flat shape as a whole, and includes a pair of flat cylindrical handle insertion portions 15 and 15 in the width direction. Yes. In the cleaning article 10 of the present embodiment, a pair of insertion portions 22 and 22 (details will be described later) in the handle 20 can be inserted into and attached to the pair of handle insertion portions 15 and 15, respectively.
In the following description, “longitudinal direction” and “width direction” mean the longitudinal direction (insertion direction) and the width direction of the handle insertion portion 15 unless otherwise specified.

  The handle insertion portion 15 is formed by joining two members 13A and 13B interposed between the upper and lower fiber layers 11 and 11 so that joint portions 16A and 16B are formed on both sides in the longitudinal direction of the handle insertion portion 15. Is formed. More specifically, the handle insertion portion 15 includes a first continuous handle insertion portion forming sheet 13A and a second handle insertion portion forming sheet 13B which are opposed to each other at the center continuous seal line 16A and the side non-continuous seal 16B (for details). (To be described later).

  One or more fiber layers 11 each comprising a fiber bundle are provided on the upper and lower surfaces of the handle insertion portion 15 in the handle insertion portion forming sheet 13. In the present embodiment, two fiber layers of the first fiber layer 11 </ b> A and the third fiber layer 11 </ b> C are provided on the upper surface of the handle insertion portion 15, and the second fiber layer is provided on the lower surface of the handle insertion portion 15. Two fiber layers 11B and a fourth fiber layer 11D are provided.

  In addition, when performing the description common to 13A of 1st handle insertion part formation sheets and the 2nd handle insertion part formation sheet 13B, the expression of "the handle insertion part formation sheet 13" is used. When the description common to the first fiber layer 11A, the second fiber layer 11B, the third fiber layer 11C, and the fourth fiber layer 11D is given, the expression “fiber layer 11” is used. When the description common to the first fiber layer 11A and the second fiber layer 11B is performed, the expression “inner fiber layer 11P” is used. In the description common to the third fiber layer 11C and the fourth fiber layer 11D, the expression “outer fiber layer 11Q” is used.

  The first fiber layer 11 </ b> A and the second fiber layer 11 </ b> B are fiber layers closest to the handle insertion part forming sheet 13 among the fiber layers 11. The third fiber layer 11C and the fourth fiber layer 11D are fiber layers outside the first fiber layer 11A and the second fiber layer 11B, respectively. Therefore, in the cleaning article 10 of the present embodiment, four layers are laminated in the order of the third fiber layer 11C, the first fiber layer 11A, the second fiber layer 11B, and the fourth fiber layer 11D from the upper layer toward the lower layer. The fiber layer is formed.

  The fiber layer 11 is formed by orienting a fiber bundle with a predetermined thickness. The fiber bundle is substantially oriented in the width direction of the handle insertion portion 15. Therefore, the first fiber layer 11 </ b> A to the fourth fiber layer 11 </ b> D are laminated so that the fiber orientation direction is substantially orthogonal to the longitudinal direction of the handle insertion portion forming sheet 13. Each fiber layer 11 has a substantially rectangular shape in plan view, and is substantially the same shape.

The fiber length of the fiber bundle constituting the fiber layer 11 is preferably 30 to 150 mm, more preferably 50 to 120 mm, from the viewpoint of dust entanglement. In the present embodiment, fibers having such a fiber length are used in a fiber bundle (tow) state. In that case, it is preferable to sufficiently open the fibers using a known opening device.
The thickness of the fiber is not particularly critical, but is preferably 0.1 to 200 dtex, particularly 2 to 30 dtex, from the viewpoints of dust entanglement and prevention of scratches on the surface to be cleaned.

It is preferable to use crimped fibers as the fibers constituting the fiber layer 11 because dust entanglement is further improved. As the crimped fiber, a two-dimensional crimp or a three-dimensional crimp can be used. The crimp rate (JIS L0208) is preferably 5 to 50%, particularly preferably 10 to 30%, from the viewpoint of improving dust entanglement. The crimp rate is defined as a percentage of the difference between the length A when the fiber is stretched and the length B of the original fiber to the length A when the fiber is stretched, and is calculated from the following equation: .
Crimp rate = (A−B) / A × 100 (%)

The length B of the original fiber means a length obtained by connecting both ends of the fiber with a straight line when the fiber is in a natural state. The natural state means a state in which one end of the fiber is fixed to a horizontal plate and hung downward by its own weight. The length A when the fiber is stretched means the length at the minimum load when the fiber is stretched until there is no crimp.
The crimp rate of the fibers is as described above, and the number of crimps is preferably 2 to 20 per cm, and more preferably 2 to 10 per cm. The number of crimps is measured in accordance with JIS L 1015 8.12.1.

It is also preferable to apply an oil component such as liquid paraffin to the fibers so that particulate matter such as fine dust can be retained. As components other than liquid paraffin, silicone, polyethylene glycol, polyethylene wax and the like, which are generally known as oil agents, can also be used. In addition, it is also effective to add a surfactant to these components in order to improve water absorption and antistatic ability.
On the other hand, it is also effective to use fibers other than white in order to improve the appearance as a product and the visibility of attached dirt.

  The handle insertion portion forming sheet 13 has a substantially rectangular shape, and the longitudinal direction thereof coincides with the longitudinal direction of the cleaning article 10. The length of the handle insertion portion forming sheet 13 is substantially the same as the length of the fiber layer 11. The width of the handle insertion portion forming sheet 13 is narrower than the width of the fiber layer 11. In other words, in the width direction of the cleaning article 10, the length in the width direction of the member 13 forming the handle insertion portion 15 is shorter than the length in the width direction of the fiber layer 11 made of the fiber bundle.

The handle insertion portion forming sheet 13 has flexibility in the longitudinal direction, and is easy to follow along the surface to be cleaned. Therefore, the fiber layer 11 bonded to the handle insertion portion forming sheet 13 can easily follow along the surface to be cleaned, so that the effect of capturing dust, dust, and the like by the cleaning article 10 is enhanced.
As a forming material of the handle insertion portion forming sheet 13, a fiber sheet such as a nonwoven fabric used in a conventional cleaning article can be used. In particular, an air-through nonwoven fabric or a spunbonded nonwoven fabric is preferable. Moreover, a nonwoven fabric, a film, synthetic paper, and those composite materials may be sufficient.

The fiber layer 11 and the handle insertion portion forming sheet 13 are joined along the longitudinal direction of the handle insertion portion forming sheet 13 with their center portions in the width direction being matched.
Specifically, the first fiber layer 11A is joined to the first handle insertion portion forming sheet 13A by a central continuous seal line 16A that extends continuously in the longitudinal direction at the center in the width direction, and the central continuous seal line 16A. Are joined by side non-continuous seals 16B extending discontinuously in the longitudinal direction at positions spaced outward in the width direction. Similarly, the second fiber layer 11B is joined to the second handle insertion portion forming sheet 13B by the center continuous seal line 16A and the side non-continuous seal 16B.
Further, the third fiber layer 11C and the fourth fiber layer 11D are joined to the first handle insertion portion forming sheet 13A and the second handle insertion portion forming sheet 13B, respectively, by the central continuous seal line 16A only at the center in the width direction. Yes.

  In the cleaning article 10 of the present embodiment, the center continuous seal line 16A located in the center in the width direction is a continuous straight line and extends between the longitudinal front and rear ends of the handle insertion portion forming sheet 13. Is formed. The width direction position of the center continuous seal line 16A is also the width direction center portion of the handle insertion portion forming sheet 13.

  The length of at least one of the handle insertion portion forming sheet 13 is 100% or more of the length along the insertion direction of the handle insertion portion 15 for the fiber layer. It is preferable that both the first handle insertion part forming sheet 13A and the second handle insertion part forming sheet 13B are longer than the fiber layer 11 from the viewpoint of easy confirmation of the insertion position of the handle 20, ease of insertion operation, and the like. The longitudinal end portion of the handle insertion portion forming sheet 13 preferably extends from 1 mm to 40 mm from the longitudinal end portion of the fiber layer 11, and more preferably extends from 1 mm to 30 mm.

  Further, when cleaning is performed by holding the handle 20 like the cleaning article 10, only the tip portion of the cleaning article 10 tends to become dirty. Considering this tendency, from the viewpoint of making it possible to use the cleaning surface without waste, it is possible to insert the handle 20 from the side opposite to the insertion direction of the handle 20 shown in FIG. It is also effective to provide two insertion openings. The cleaning article 10 of this embodiment has such a form as will be described later. Also in this case, it is preferable that the end portion in the longitudinal direction of the handle insertion portion forming sheet 13 extends from the end portion in the longitudinal direction of the fiber layer 11A on the other insertion port side as well.

  The handle insertion portion forming sheet 13 has an unjoined portion of at least 1 mm or more at the end of the handle insertion portion 15 in the portion extending from the fiber layer 11 in this embodiment in order to improve the mounting property. It is preferable. The unbonded portion is more preferably 5 mm or more.

Side discontinuous seals 16B and 16B (portions surrounded by broken lines in FIG. 3) are respectively provided outside the center continuous seal line 16A in the width direction.
The side non-continuous seal 16B is composed of an assembly of 2 to 100 point seals 18 spaced in the longitudinal direction. The number of point seals 18 constituting the assembly is more preferably 2 to 50. The point seal 18 of this embodiment is formed from a circular heat seal. The point seals 18 are arranged so that the positions in the longitudinal direction coincide with each other, and are formed at equal intervals in the longitudinal direction. From the viewpoint of preventing the point seal 18 from being caught when the handle 20 is inserted into the handle insertion portion 15, the interval in the longitudinal direction of the point seal 18 is preferably 5 to 40 mm.

The width direction interval W1 between the center continuous seal line 16A and the side non-continuous seal 16B is preferably 5 to 90 mm, more preferably 5 to 45 mm.
The width-direction interval W1 is such that, in the state where the opposing handle insertion portion forming sheets 13A and 13B overlap, the edge on the inner side in the width direction of the point seal 18 forming the side non-continuous seal 16B and the center continuous seal line 16A It is the distance measured along the width direction of the handle insertion part forming sheet 13 between the outer edges in the width direction. In the present embodiment, the width direction interval W <b> 1 is the width of the handle insertion portion 15.

  The total seal length of the side non-continuous seal 16B (the length when the non-continuous portion of the side non-continuous seal is virtually packed and regarded as a continuous line) is the length along the handle insertion portion 15 for the inner fiber layer 11P. Is preferably 10% or more, and more preferably 15% or more. Further, the total seal length of the side non-continuous seal 16B is preferably 10% or more of the length along the insertion direction of the handle insertion portion 15 with respect to the central continuous seal line 16A, and more preferably 15% or more. .

In the region between the point seals 18 and 18 adjacent in the longitudinal direction in the side non-continuous seal 16B, between the handle insertion portion forming sheet 13 and the inner fiber layer 11P and between the opposing handle insertion portion forming sheets 13A and 13B. (Details will be described later) are not joined.
In addition, the shape of the point seal | sticker 18 may be an ellipse, a rectangle, etc., for example. The intervals in the longitudinal direction of the point seals 18 may not be equal.

Accordingly, the inner fiber layer 11P is joined at three locations of the center continuous seal line 16A and the two side non-continuous seals 16B as shown in FIG. Or as shown in FIG.4 (b), it joins only in one place of the center continuous seal line 16A. As shown in FIG. 4A and FIG. 4B, the outer fiber layer 11Q is joined at only one central continuous seal line 16A in any cross section as seen in a longitudinal sectional view along the width direction.
In FIGS. 4A and 4B, the second fiber layer 11B and the fourth fiber layer 11D are not shown.

  Moreover, as shown in FIG.4 (c), it is preferable that the width direction edge part of 11 A of fiber layers is extended from the width direction edge part of the handle insertion part formation sheet 13. FIG. The handle insertion portion forming sheet 13 is preferably 1 to 20 mm shorter, more preferably 2 to 15 mm shorter on at least one side than the inner fiber layer 11P in the width direction.

  In the cleaning article of the present invention, the width in the width direction of the handle insertion portion forming sheet 13 is shorter than the length in the width direction of the fiber bundle forming the fiber layer 11 in the width direction of the cleaning article. Only the fiber layer 11 of the fiber bundle is present on the surface of the article 10 for use. Furthermore, since there are a plurality of sealing positions of the fiber layer 11 and a plurality of patterns of brushes are formed and the raising directions are different, the fibers easily rise and support each other by air blow or the like. Therefore, as shown in FIG. 5, it is possible to make it the form which covers the perimeter of the cleaning article 10 with the front-end | tip of the brush by a fiber. At this time, it is preferable to cover the entire surface of the cleaning article 10 by raising the fiber layer 11 in a substantially cylindrical shape so as to cover the central continuous seal line 16A.

  For the formation of the raised form of the substantially cylindrical fiber layer 11 shown in FIG. 5, the raising method for the cleaning article of the present invention is suitably used. The method for raising a cleaning article according to the present invention includes a flat and cylindrical handle insertion portion 15 and a fiber layer 11 made of a fiber bundle joined to the upper and lower sides of the handle insertion portion 15 by a central continuous seal line 16A. For the cleaning article 10 that can be attached by inserting 20 into the handle insertion portion 15, the fiber layer 11 made of a fiber bundle is opened, and the fiber layer 11 is covered so as to cover the central continuous seal line 16A. This is a method in which a brush is randomly raised in a three-dimensional direction to form a substantially cylindrical shape. As a method for opening the fiber layer 11, for example, air blowing is used.

  The center continuous seal line 16A and the side non-continuous seal 16B are formed by known joining means such as heat sealing and adhesive bonding. When the handle insertion portion forming sheet 13 is made of a heat-fusible material, the center continuous seal line 16A and the side non-continuous seal 16B can be formed by heat fusion.

  A pair of flat cylindrical handle insertion portions 15 and 15 are formed by joining opposite handle insertion portion forming sheets 13A and 13B with three side non-continuous seals 16B, a central continuous seal line 16A, and a side non-continuous seal 16B. Is formed. That is, the three side non-continuous seals 16B, the center continuous seal line 16A, and the side non-continuous seals 16B include a joint seal portion between the handle insertion portion forming sheet 13 and the fiber layer 11, and a handle insert portion forming sheet 13A facing each other. It also serves as a joint seal part between 13B.

  The handle insertion portion 15 is formed over the entire length between the front and rear end portions in the longitudinal direction of the handle insertion portion forming sheet 13. In the handle insertion portions 15 and 15, the handle insertion portion forming sheets 13 </ b> A and 13 </ b> B that are opposed to each other can be in contact with each other when the handle 20 is not inserted, but when the handle 20 is inserted, The insertion portion forming sheets 13A and 13B are separated from each other to form a cylindrical space.

  The handle insertion portion 15 has an insertion port at each of the longitudinal front and rear end portions of the handle insertion portion forming sheet 13. Therefore, the handle 20 can be inserted into the handle insertion portion 15 from any insertion port.

  Next, the handle 20 will be described. As shown in FIG. 6, the handle 20 includes a gripping portion 21 and a pair of insertion portions 22 and 22 that are branched into two forks from the tip of the gripping portion 21. The grip portion 21 and the insertion portion 22 form a predetermined angle. The insertion part 22 has an elongated flat plate shape. Since the insertion portion 22 has such a shape, flexibility is imparted to the insertion portion 22. If the insertion portion 22 is flexible, the cleaning object 10 can easily follow the surface to be cleaned when the surface to be cleaned having a curved surface or unevenness is cleaned, and the dust removal efficiency is increased. It is advantageous.

  The pair of insertion portions 22 can be inserted into the pair of handle insertion portions 15 in the cleaning article 10, respectively. A hook portion 23 having a shorter length than the insertion portion 22 is provided between the insertion portions 22 and 22. The hook portion 23 has its tip turned upward at a predetermined angle. The hook portion 23 is detached from the cleaning article 10 by engaging with a notch 19 (details will be described later) in the cleaning article 10 in a state where the insertion section 22 is inserted into the handle insertion section 15. It is difficult.

  The forming material of the handle 20 is preferably a thermoplastic resin, and specifically, polyethylene, polypropylene, polyvinyl chloride, polystyrene, ABS resin, acrylic resin, and the like are preferable from the viewpoint of molding processability and flexibility.

The cleaning article 10 of this embodiment is used for cleaning in a state where the pair of insertion portions 22 and 22 in the handle 20 are inserted and fixed to the pair of handle insertion portions 15 and 15, respectively.
The width of the handle insertion portion 15 is set to be approximately the same as the width of the insertion portion 22 of the handle 20 from the viewpoint of allowing the handle 20 to easily enter the handle insertion portion 15 and not easily coming off from the handle insertion portion 15 during cleaning. Is preferred. In a state where the pair of insertion portions 22 and 22 of the handle 20 are respectively inserted into the pair of handle insertion portions 15 and 15 of the cleaning article 10, the handle insertion portion 15 corresponds to the thickness of the insertion portion 22 in the width direction. The insertion part 22 is tightened.

The front and rear end portions in the longitudinal direction of the handle insertion portion forming sheet 13 are folded inward toward the central portion in the longitudinal direction, and the central portion in the width direction of the folded portion is gripped by a central continuous seal line 16A. The insertion portion forming sheet 13 is joined.
At the front and rear end portions in the longitudinal direction of the handle insertion portion forming sheet 13, a notch 19 is provided as an engaging means (a portion that can be engaged with the handle 20) that engages with the hook portion 23 of the handle 20.

  The notch 19 has a U-shape and is opened upward from the inside in the longitudinal direction of the handle insertion portion forming sheet 13 when the hook portion 23 is engaged. When the notch 19 is engaged with the hook portion 23, the handle 20 is restricted from moving in the longitudinal direction of the handle insertion portion 15, particularly to the outside in the longitudinal direction, so that the inserted handle 20 is removed from the cleaning article 10. It is designed to be fixed stably.

Since the notch 19 is formed in both the handle insertion portion forming sheets 13A and 13B facing each other, the handle 20 can be used regardless of whether the hook portion 23 is disposed on the upper surface side or the lower surface side of the cleaning article 10. It can be inserted into the insertion portion 15 and fixed.
In this embodiment, the length of the handle insertion portion 15 is substantially the same as the length of the fiber layer 11 (the length along the insertion direction of the handle insertion portion 15). In consideration of wearability and the like, it is preferable that the length of the handle insertion portion forming sheet 13 is longer than the length of the fiber layer 11 and the length of the handle insertion portion 15 is longer than the length of the fiber layer 11. Yes (not shown).

  Furthermore, it is preferable to reinforce the end portion of the handle insertion portion forming sheet 13 by a known reinforcing means in order to easily apply a force to the handle 20 when attached and to prevent breakage when the force is applied. In the present embodiment, the end portions of the two handle insertion portion forming sheets 13 are folded and integrated at the handle insertion portion 15 to increase the sheet breaking strength.

Other configurations for increasing the sheet breaking strength include the following. As a first example, two grip insertion portion forming sheets 13 are formed from a heat-meltable fiber, and the end portion of the handle insertion portion forming sheet 13 is made into a melt film to increase the sheet breaking strength. Can be mentioned. As a second example, the end portion of the two handle insertion portion forming sheets 13 may be configured such that the sheet breaking strength is increased by joining other sheet materials.
Further, when the cut 19 is formed as the engaging means for engaging with the handle 20 as described above, it is preferable to reinforce only the periphery thereof by the reinforcing means described above.

  According to the cleaning article 10 of the present embodiment configured as described above, the inner fiber layer 11P closest to the handle insertion part forming sheet 13 among the fiber layers 11 is located in the center part in the width direction on the handle insertion part forming sheet 13. Are joined by a central continuous seal line 16A continuously extending in the longitudinal direction, and at a position spaced apart from the central continuous seal line 16A in the width direction, the side discontinuous seal 16B extends discontinuously in the longitudinal direction. It is joined by.

  Therefore, the inner fiber layer 11P joined only to the center continuous seal line 16A to the handle insertion portion forming sheet 13 forms a brush with a fiber bundle (tow) on the lower side of the center portion in the width direction of the cleaning article 10. The

  On the other hand, even in the inner fiber layer 11P joined to the handle insertion portion forming sheet 13 by the center continuous seal line 16A and the side non-continuous seal 16B, a brush near the end in the width direction of the cleaning article 10 is formed.

  Further, the outer fiber layer 11Q joined to the handle insertion portion forming sheet 13 only by the central continuous seal line 16A forms a brush with a fiber bundle (tow) on the upper side in the center in the width direction of the cleaning article 10.

  When there are a plurality of fiber sealing positions and a plurality of patterns of brushes are formed as in the cleaning article of the present invention, the patterns for supporting the raised fibers are different for each brush, and the support for the raised fibers is different. Matching is effected effectively, and a cleaning article having a different napping direction is formed. This tendency works effectively even after a load is applied during use, after use, etc., and exhibits a certain level of compression recovery. This effect covers the entire surface of the cleaning article 10 so that the brush on the surface of the cleaning article is effective for the cleaning operation. Furthermore, the fibers rise by air blow or the like and are supported to each other. As shown in FIG. 5, the entire periphery of the cleaning article 10 can be covered with the tips of the brushes of the fibers. At this time, it is preferable to cover the entire surface of the cleaning article 10 so as to cover the central continuous seal line 16A.

  In the present embodiment, these effects are combined, and at the time of cleaning, the raising property of the fiber layer 11 and the compression recovery property of the fiber layer 11 are excellent, the followability to the uneven surface of the cleaning object is high, and the cleaning performance is excellent. ing. Further, in the present invention, since the handle insertion portion forming sheet 13 is shorter than the fiber bundle forming the fiber layer 11 in the width direction of the cleaning article, it is the fiber by the fiber bundle that is present on the surface of the cleaning article. Only layer 11 is present. Thereby, a fiber bundle functions more effectively and cleaning performance increases. For example, the followability to the surface of the cleaning object is high, and the unevenness is easily cleaned. Further, it is possible to clean an object to be cleaned that requires delicate handling.

  Next, the cleaning article 10 according to the second embodiment of the present invention will be described with reference to FIG. Regarding the second embodiment, the description in detail regarding the first embodiment is applied as appropriate to points that are not particularly described. Moreover, in FIG. 7, the same code | symbol is attached | subjected to the same member as FIGS.

As shown in FIG. 7, the cleaning article 10 of the second embodiment is provided with only one handle insertion portion 15. Two identical and vertically long handle insertion portion forming sheets 13A and 13B are bonded together by two side non-continuous seals 16B and 16B extending in the longitudinal direction to form a cylindrical handle insertion portion 15. In the two side non-continuous seals 16B and 16B (portions surrounded by dotted lines in FIG. 7), as shown in FIG. 7, a point seal 18 by circular heat sealing is provided on the handle insertion portion forming sheets 13A and 13B. It is formed side by side at equal intervals in the longitudinal direction. The center continuous sealing line 16A by linear heat sealing provided in the cleaning article of the first embodiment joins the handle insertion portion forming sheet 13 and the fiber layer 11, but inserts two grips. The part forming sheets 13A and 13B are not joined to each other.
In the present embodiment, if the width of the insertion portion of the handle 20 has substantially the same width as that of the handle insertion portion 15, the shape of the insertion portion branches into two branches as shown in FIG. 6 as in the first embodiment. Alternatively, it may be an integral shape that is not branched as shown in FIG.

  According to the second embodiment, the same effect as the first embodiment can be obtained. Further, when the insertion portion of the handle 20 has an integral shape that is not branched into two branches as shown in FIG. 8, the rigidity of the insertion portion is enhanced by the handle 20. The operability is improved when cleaning the corners or the gap between the wall and the furniture, or when scraping and removing the dust stuck to the surface to be cleaned.

  Next, with respect to one embodiment of the method for manufacturing a cleaning article of the present invention, referring to FIGS. 9 to 14, taking as an example the case of manufacturing the cleaning article 10 of the second embodiment shown in FIG. 7 described above. While explaining. In FIG. 13, the manufacturing process on the second continuum 32B side is substantially the same as the manufacturing process on the first continuum 32A side, and thus illustration is omitted.

In the manufacturing method of this embodiment, the cleaning article 10 is manufactured through the following steps (1) to (5).
(1) Manufacturing process of the first continuum and the second continuum (2) The first continuum and the second continuum are overlapped and fixed, and further continuous on the first continuum and the second continuum, respectively. (3) Step of manufacturing a laminated body for forming a laminated body by stacking and fixing the third fiber layer and the fourth fiber layer composed of the bundles of fibers obtained (3) Step of cutting the laminated body to obtain individual cleaning articles (4) (5) Cleaning article, wherein a central portion sandwiched between a pair of break guide wires is left from the first belt-like member and the second belt-like member in the cleaning article, and an outer portion connected to the central portion is cut off. Opening the fiber layer so that the fiber layer is randomly raised in a three-dimensional direction

(1) Manufacturing process of first continuum and second continuum Although only the first continuum 32A will be described and description of the second continuum 32B will be omitted, the first continuum 32B is also the first continuum Manufactured in the same manner as the body 32A.
In this step, as shown in FIGS. 9, 10 and 13, the first fiber layer 11A made of a continuous fiber bundle and the first belt-like member 31A made of a continuous non-woven fabric are overlapped by a central continuous seal line 16A. It is a step of manufacturing the first continuous body 32A by fixing, and is usually performed before the step (2) of manufacturing the laminated body 34 by stacking and fixing the third fiber layer 11C composed of continuous fiber bundles.

In this step, as shown in FIG. 13, after unwinding the first belt-shaped member 31A made of a continuous nonwoven fabric, as shown in FIG. 9, folding the both side portions in the longitudinal direction of the first belt-shaped member 31A In this way, the first belt-like member 31A is subjected to perforation (breaking induction line) processing to form the breaking induction line 41. The break guide wire 41 is formed intermittently over the entire lengthwise direction of the first strip member 31A. As a result, the first belt-like member 31 </ b> A is partitioned into a central portion 42 sandwiched between the pair of breakage guide wires 41 and an outer portion 43 connected to the center portion 42 via the breakage guide wires 41. Further, as shown in FIGS. 10 and 13, a first fiber layer 11 </ b> A composed of a continuous fiber bundle is supplied on the first band-shaped member 31 </ b> A (outer surface side), and the first band-shaped member 31 </ b> A and the first fiber The layer 11A is joined by a central continuous seal line 16A to form a first continuous body 32A. The center continuous seal line 16A is intermittently formed over the entire longitudinal direction of the first fiber layer 11A.

  As described above, by forming the perforation (breaking guide line) 41 in the first band-shaped member 31A before the first fiber layer 11A is arranged, the first band-shaped member 31A is changed to the pair of break-inducing lines 41. The fiber layer 11 is not broken during the step (4) of cutting the outer portion 43 connected to the central portion 42 through the break guide wire 41 while leaving the sandwiched central portion 42. As described above, the first belt-like member 31A is easily broken.

(2) The first continuous body and the second continuous body are stacked and fixed, and the third fiber layer and the fourth fiber layer made of continuous fiber bundles are stacked on the first continuous body and the second continuous body, respectively.

The side non-continuous seal 16B is intermittently formed over the entire longitudinal direction of the first fiber layer 11A and the second fiber layer 11B. In addition, it is preferable that the dotted | punctate side discontinuous seal | sticker 16B near the handle insertion part 15 is formed so that the space | interval may be expanded so that the insertion port of the handle insertion part 15 can be ensured.

  Further, as shown in FIGS. 12 and 13, a third fiber layer 11C composed of continuous fiber bundles is stacked on the first continuous body 32A and fixed by the central continuous seal line 16A, and the second continuous body 32B The fourth fiber layer 11D is overlaid and fixed by the center continuous seal line 16A. These fixations are performed in a non-peelable manner by known joining means such as heat sealing and ultrasonic sealing. These fixations may be partial bonding using a large number of dots, lattices, spirals, or the like. Moreover, joining by hot melt may be sufficient. Thereby, the laminated body 34 in which the continuous first fiber layer 11A and the second fiber layer 11B and the continuous third fiber layer 11C and the fourth fiber layer 11D are intermittently formed in the longitudinal direction is obtained.

(3) The process of cut | disconnecting a laminated body and obtaining each cleaning article In this process, as shown in FIG. 13, the laminated body 34 is cut | disconnected and the individual cleaning articles 35 are obtained. The cleaning article 35 means an unfinished cleaning article.

(4) A step of cutting out the outer portion connected to the central portion from the first and second belt-shaped members in the cleaning article, leaving the central portion sandwiched between the pair of break guide wires. As shown in FIG.12 and FIG.14, about each cut | disconnected article | item 35 for cleaning, from each of the 1st strip | belt-shaped member 31A and the 2nd strip | belt-shaped member 31B, it uses a pair of fracture | rupture guide wire 41 formed beforehand. The cleaning article 10 is obtained by cutting out the outer portion 43 connected to the central portion 42 while leaving the central portion 42 sandwiched between the breaking guide wires 41. The central portion 42 after the outer portion 43 is cut becomes the handle insertion portion forming sheet 13. Further, a handle insertion portion 15 is formed between the opposing handle insertion portion forming sheets 13A and 13B.

(5) The process of opening the fiber layer of the cleaning article so as to be raised randomly in the three-dimensional direction This process is the final stage of production, and in this process, the central part sandwiched between the break guide lines 41 Air blow is applied to the fiber layer 11 in the cleaning article 10 from which the outer portion 43 has been cut away leaving 42, and the fiber layer 11 is opened and raised, and a central continuous seal line as shown in FIG. The cleaning article 10 is obtained in such a manner that the entire periphery of the cleaning article 10 is covered with the tip of a brush made of fiber so as to cover 16A.
The cleaning article 10 can be efficiently manufactured in this way.

In the manufacturing method of this embodiment, it is preferable to further have the following process (6).
(6) Step of reinforcing at least the vicinity of the fracture guide line 41 in the central portion 42 of the first belt-like member 31A and / or the second belt-like member 31B This step is center continuous with the first continuum 32A and the second continuum 32B. It is performed before, after, or during the process of intermittently forming the fracture guide wire 41 in the first continuous body 32A and the second continuous body 32B before the process of intermittently forming the seal line 16A. That is, this step can be performed either before, after, or during the step of intermittently forming the fracture guide wire 41. However, when the central continuous seal wire 16A is formed, the first fiber layer 11A and the second fiber layer 11A are formed. Since the break guide wire 41 is hidden by the fiber layer 11B, it is necessary to carry out before the step of intermittently forming the central continuous seal wire 16A.

  In this step, both the first strip member 31A and the second strip member 31B, only the first strip member 31A, or only the second strip member 31B can be reinforced. The reinforcement may be performed at least in the vicinity of the break guide line 41 in the central portion 42, and is preferably performed on a region having a width of 20 to 3 mm.

  Examples of the method for reinforcing the first strip member 31A and the second strip member 31B include a method of forming the strip member itself into a melt film, and a method of applying an adhesive such as a hot-melt adhesive to the strip member. These melt film formation, adhesive application, and the like may be performed on both the first belt-like member 31A and the second belt-like member 31B (in this case, it is preferable to join both members). May be applied only to

  In the cleaning article manufactured through this step, the vicinity of the break guide line 41 in the central portion 42 of the first belt-like member 31A and / or the second belt-like member 31B is reinforced. The scraping force by the end in the width direction is improved.
