Description

The present invention relates to a wiping body for cleaning a surface to be cleaned such as a floor surface, and more specifically, a wiping body capable of cleaning and collecting dust and holding the collected dust inside the wiping body. Regarding the body and cleaning tools using the wiping body.

Conventionally, a wiping body capable of cleaning and collecting dust and holding the collected dust inside the wiping body and a cleaning tool using the wiping body have been developed, and some patent documents have been published. exist.
First, there is a "multi-layered cleaning article" described in Japanese Patent Application Laid-Open No. 11-267079 (Patent Document 1). FIG. 18 of the present application shows a wiper and a cleaning tool in Patent Document 1. The wiping body is shown as a cleaning article S, and a cleaning article S having a three-layer structure in which both sides of a layer 102 having no opening is narrowed by layers 101 and 101 having an opening is shown. In the embodiment, it is described that the layer 102 having no opening and the layer 101 having an opening are both composed of a non-woven fabric, and the opening 103 is opened by a water jet or a needle punch. Dust is held inside the opening 3 and is blocked from passing by a layer 102 having no opening.
The problem with Patent Document 1 is that since the openings 103 are opened in the non-woven fabric by a water jet or a needle punch, the number density of the openings 103 is limited to 10 to 100 / cm2 as described in [0016]. In the experience of the inventor, it is considered that the ratio of the total opening area of a large number of openings 103 to the total area of the non-woven fabric, that is, the surface aperture ratio is limited to 50%. Further, as shown in [0014], the thickness of the layer 101 having the opening 103 is about 0.3 to 2.0 mm, and 2.0 mm is considered to be the limit. Therefore, even if the floor surface is cleaned with the cleaning mop 110 obtained by winding the cleaning article S around the cleaning plate 111, the amount of dust that can be held in the opening 103 is considerably small, and it is considered that the cleaning performance is insufficient.

Secondly, there is a "floor surface cleaning sheet" described in Japanese Patent No. 3557047 (Patent Document 2). FIG. 19 of the present application shows a wiper in Patent Document 2. As can be seen from claim 1, "a confounding non-woven fabric obtained by a spunlace method, which is composed of a non-woven fabric that has been perforated, has a numerical aperture of 30 to 300 / in 2, and has an aperture ratio of 30 to 300. A floor cleaning sheet characterized by being composed of 5 to 50% entangled non-woven fabric ... ”is described.
The problem of Patent Document 2 is that the surface aperture ratio is only 5 to 50%, and the thickness of the entangled non-woven fabric is empirically limited to about 2 mm. As a result, even if a cleaning mop is produced to clean the floor surface, the amount of dust that can be held in the opening is small, and it can be pointed out that the cleaning performance is insufficient.

Thirdly, there is a "cleaning sheet" described in Japanese Patent Application Laid-Open No. 2011-229871 (Patent Document 3). FIG. 20 of the present application shows a cleaning sheet in Patent Document 3. The cleaning sheet 301 is formed by opening a large number of holes 303 in the non-woven fabric 302. Fibers 304 that traverse the inside of the opening portion are present in the opening portion 303 to prevent dust such as bread crumbs from falling out from the opening portion 303. Then, it is shown that the cleaning sheet 301 is wound around the pedestal 311 to form the mop 310, and the floor material 314 is cleaned by the mop 310.
As a problem of Patent Document 3, the maximum diameter of the perforated portion is limited to 1 mm to 3 mm or less in claim 3, and [0012] states, "In order to more reliably secure the dust collecting performance as the cleaning sheet 1. The thickness is preferably 0.01 to 3 mm. " Regarding the number of holes, the number of holes was described in [0024], and the dimensions of any of the spunlace nonwoven fabrics of Examples 1 to 8 were 210 mm in length × 310 mm in width, 0.8 mm in thickness, and the holes were formed. The arrangement pattern and the number are in a grid pattern, and it is described as "20 vertical / 1 row x 40 horizontal / 1 row ...". That is, since the total area of the non-woven fabric = 65100 mm2 and the total area of the opened holes = 5652 mm2, the surface aperture ratio = 5652/65100 × 100% = 8.7%.
That is, no matter how hard you try, in Patent Document 3, the surface aperture ratio is less than 50% and the thickness is 3 mm or less, so that the amount of dust that can be held in the opening is too small, and the cleaning performance is remarkably inadequate. be.

As is clear from the above, in the conventional mop, there is a technical idea of opening a large number of holes in the non-woven fabric and accumulating and holding dust in the holes. However, since holes are made in the finished non-woven fabric after the fact, there is a limit to the number of holes to be opened, and the surface aperture ratio given by the total hole area / non-woven fabric area x 100 (%) can be set to 50% or more. It was impossible. Further, it is difficult for the thickness of the non-woven fabric to exceed 3 mm, and since the hole volume given by the hole area × the hole depth is small, there is a drawback that the amount of dust accumulated and held inside the hole is considerably reduced.

On the other hand, three-dimensional fabrics called three-dimensional knits and three-dimensional woven fabrics are being developed in a technical field completely different from the cleaning field. Layers in which a large number of hexagons and quadrangles are periodically arranged are arranged in parallel with two layers separated from each other at the top and bottom, and are connected to each other with connecting threads to form a thick three-dimensional fabric. Even if the two layers of the front and back surfaces are compressed, they are elastic due to the connecting thread, and can be used for nursing care products such as incontinence pants, heel pads, and elbow pads. In addition, for clothing such as dating, compensating, and waist pads, cushioning and cushioning materials such as protective caps, slippers, sandals, and land cell pads, and seat covers for golf carts, office chairs, and wheelchair cushions. It is being used as a sheet material.
The following fourth and fifth patent documents are exemplified as documents for three-dimensional fabrics.

Fourth, there is a "three-dimensional knitted laminate" described in Japanese Patent No. 3996531 (Patent Document 4). FIG. 21 of the present application shows a cross-sectional view of the three-dimensional knitted fabric 401 disclosed in Patent Document 4. The three-dimensional knitted fabric 401 is configured by connecting the front knitted fabric 402 and the back knitted fabric 403 with a large number of monofilament connecting threads 404. The three-dimensional knitted body 401 is formed by laminating only two stages of the three-dimensional knitted fabric 401. That is, the second-stage three-dimensional knit is formed by connecting the front knit fabric 406 and the back knit fabric 407 with a large number of monofilament connecting threads 408, and the first-stage three-dimensional knit is formed by connecting the front knit fabric 409 and the back knit fabric 410. It is formed by connecting with a large number of monofilament connecting threads 411.
However, as described in [0001], the three-dimensional knitted body of Patent Document 4 includes cushioning materials for vehicles such as automobiles, railroad vehicles, aircraft, child seats, and strollers, office use, bedding, and bed pads. It is used as a cushioning material for mattresses, floor slip prevention mats, furniture, pillows, cushions, etc. Therefore, it is clear that the use of the cleaning tool, which is the object of the present application, for the wiping body is not intended at all.

Fifth, there is a "concrete anticorrosion lining sheet" described in Japanese Patent Application Laid-Open No. 2006-206081 (Patent Document 5). FIG. 22 of the present application shows a three-dimensional view and a cross-sectional view of the three-dimensional woven knitted fabric 502 disclosed in Patent Document 5.
In the three-dimensional woven knitted fabric 502, the knitted fabric 503 of the surface layer and the knitted fabric 504 of the back layer are planes in which a large number of hexagonal annular yarns are periodically arranged, and the annular yarns of the surface layer and the back layer are a large number of connecting yarns. It is configured to be connected by 505 and have a thickness. The three-dimensional woven knitted fabric 502 is embedded in the upper part of the concrete 506, and the upper surface thereof is covered with the thermoplastic resin sheet 501 to protect the concrete 506 from corrosion.
However, the three-dimensional woven knitted fabric 502 of Patent Document 5 is exposed to a corrosive atmosphere such as a sewerage facility, a kitchen abatement facility, and a sewage tank, for example, a hydrogen sulfide atmosphere, as described in [0001]. It is used as a concrete anticorrosion lining sheet that protects concrete structures. That is, it is clear that the use of the cleaning tool for the purpose of the present application as a wiping body is not intended at all.

Japanese Unexamined Patent Publication No. 11-267079 Japanese Patent No. 3557047 Japanese Unexamined Patent Publication No. 2011-229871 Japanese Patent No. 3996531 Japanese Unexamined Patent Publication No. 2006-206081

As described above, in Patent Document 1, since the openings 103 are opened in the non-woven fabric by a water jet or a needle punch, the number of openings is limited, and the total area of the non-woven fabric is the total opening area of many openings. The ratio to, that is, the surface aperture ratio is limited to 50%. Moreover, the non-woven fabric has a drawback that the thickness is thin, the amount of dust that can be accumulated and held in the opening is considerably small, and the cleaning performance is insufficient.

Further, Patent Document 2 states that the surface aperture ratio is only 5 to 50%, and the thickness of the entangled nonwoven fabric is empirically limited to about 2 mm. As a result, even if a cleaning mop is produced to clean the floor surface, the amount of dust that can be held in the opening is small, and it is pointed out that the cleaning performance is insufficient.

Further, in Patent Document 3, no matter how hard the effort is made, the surface aperture ratio is less than 50% and the thickness is 3 mm or less, so that the amount of dust that can be held in the opening is too small and the cleaning performance is insufficient.

On the other hand, the three-dimensional knitted laminate of Patent Document 4 includes cushioning materials for vehicles such as automobiles, railroad vehicles, aircraft, child seats, and strollers, office use, bedding, bed pads, mattresses, floor slip prevention mats, furniture, pillows, cushions, etc. It is clear that it is used as a cushioning material and is not intended to be used as a wiping body for cleaning tools.

Similarly, the three-dimensional woven knitted fabric of Patent Document 5 is used as a concrete anticorrosion lining sheet that protects concrete structures exposed to corrosive atmospheres such as sewerage facilities, kitchen abatement facilities, and sewage tanks, for example, hydrogen sulfide atmosphere. It is clear that it is used and that the use of cleaning tools for wiping bodies is not considered at all.

Therefore, in the present invention, a three-dimensional fabric such as a three-dimensional woven fabric or a three-dimensional knitted fabric is used for a wiping body of a cleaning tool, which has never been expected in the past, and the surface opening ratio due to a large number of holes formed in the wiping body is increased to 90% or more. By adjusting and adjusting the depth of the hole freely, a large amount of dust on the surface to be cleaned can be collected, and at the same time, a large amount of dust can be accumulated and held in the hole, and the held dust can be collected and held in the hole. Provided is a three-dimensional mesh type wiping body for cleaning that can be sucked and cleaned by means of a three-dimensional mesh type cleaning tool and a three-dimensional mesh type cleaning tool using the same.

The present invention has been made to solve the above problems, and the first aspect of the present invention is a three-dimensional cloth as the wiping body in a wiping body attached to a cleaning tool and used for wiping cleaning. In the three-dimensional fabric, two mesh layers in which a large number of meshes are arranged in a plane substantially periodically are laminated via an interval layer, and the two mesh layers are on the upper side having the same shape as each other. The mesh and the lower mesh are arranged so as to communicate with each other vertically, and the two annular threads forming the upper mesh and the lower mesh that communicate with each other vertically are formed by a plurality of connecting threads in a circular manner. The side surface of the connecting yarn is formed by being connected, and the spacing layer is configured to include the side surface of the connecting yarn inside, and a three-dimensional mesh is formed by the upper mesh, the lower mesh, and the side surface of the connecting yarn that are communicated vertically. The three-dimensional mesh has an internal space and an opening surface between the upper mesh and the lower mesh, and when cleaned with the cleaning tool, dust is collected from the opening surface of the mesh and the internal space of the three-dimensional mesh is collected. It is a three-dimensional mesh type wiper that holds dust.

In the second aspect of the present invention, one of the opening surface of the upper mesh and the opening surface of the lower mesh is made a closing surface by a closing thread, and the other is left as an opening surface, and dust is formed from the opening surface. It is a three-dimensional mesh type wiping body that collects dust and holds dust in the internal space, and makes it difficult for the dust held in the internal space to be released from the closed surface.

In the third embodiment of the present invention, a three-dimensional cloth is used as the wiping body in a wiping body attached to a cleaning tool and used for wiping and cleaning, and in the three-dimensional cloth, a large number of meshes are formed in a substantially periodic plane. By stacking three or more layers of mesh layers arranged in a shape via an interval layer, the interval layers exist in a laminated state of two or more layers, and the adjacent two network layers have the same shape as the upper network and the lower side. The meshes of the above are arranged so as to communicate with each other vertically, and the two annular threads forming the upper mesh and the lower mesh that are communicated vertically are connected to each other in a circumferential shape by a plurality of connecting threads. A thread side surface is formed, and the spacing layer is configured to include the connecting thread side surface inside, and a three-dimensional mesh is formed by an upper mesh, a lower mesh, and a connecting thread side surface that communicate with each other in the upper and lower directions. Has an internal space and has an opening surface in the upper mesh and the lower mesh, and in one spacing layer, a large number of the three-dimensional meshes are arranged substantially periodically, and the spacing layer is 2. By stacking more than one layer, two or more of the three-dimensional meshes are laminated directly above to form an enlarged three-dimensional network, and in the expanded three-dimensional network, an enlarged internal space in which two or more of the internal spaces are laminated in a continuous manner is formed. It is formed and has an opening surface in the uppermost mesh and the lowermost mesh, and is configured by arranging a large number of enlarged three-dimensional meshes substantially periodically. When cleaned with the cleaning tool, the opening of the enlarged three-dimensional mesh is formed. It is a three-dimensional mesh type wiping body that collects dust from the surface and holds the dust in the expanded internal space of the enlarged three-dimensional mesh.

In the fourth aspect of the present invention, one of the opening surface of the mesh on the uppermost surface and the opening surface of the mesh on the lowermost surface is made a closing surface by a closing thread, and the other is left as an opening surface from the opening surface. It is a three-dimensional mesh type wiping body that collects dust and holds the dust in the enlarged internal space so that the dust held in the enlarged internal space is not discharged from the closed surface.

A fifth aspect of the present invention is a three-dimensional mesh type wiper having two or more kinds of mesh shapes in the three-dimensional cloth.

A sixth aspect of the present invention is a three-dimensional mesh type wiper in which an adsorbent that adsorbs and holds dust is supported on the three-dimensional cloth.

A seventh aspect of the present invention is a three-dimensional mesh type wiper in which the three-dimensional cloth is charged with a fixed charge or static electricity.

An eighth aspect of the present invention is a three-dimensional mesh type wiping body in which the three-dimensional cloth is combined with a cleaning wiping material other than the three-dimensional cloth as the wiping body.

In the ninth aspect of the present invention, any of the three-dimensional mesh-type wiping bodies of the first to eighth forms is used, and the grip portion to which the three-dimensional mesh-type wiping body is mounted is connected to the grip portion. When the three-dimensional mesh type wiping body composed of a handle portion is brought into contact with the surface to be cleaned for cleaning, dust is collected from the surface to be cleaned through the opening surface of the mesh, and the internal space of the three-dimensional mesh or the expanded three-dimensional mesh. It is a three-dimensional mesh type cleaning tool that holds dust in the enlarged internal space.

In the tenth aspect of the present invention, the grip portion is made of a substrate, the central portion of the wiping body of the three-dimensional mesh type wiping body is arranged so as to be in contact with the cleaning side surface of the grip portion, and both ends of the three-dimensional mesh type wiping body are arranged. This is a three-dimensional mesh-type cleaning tool that fixes a portion to the grip portion and presses the three-dimensional mesh-type wiping body against the surface to be cleaned for cleaning.

In the eleventh embodiment of the present invention, the three-dimensional mesh type wiping body has a curved portion folded back in a curved shape, its left and right ends are connected to the grip portion, and a space portion is inside the curved portion. Is formed, and the curved portion is pressed against the surface to be cleaned to clean the three-dimensional mesh type cleaning tool.

In the twelfth aspect of the present invention, the left and right ends are joined to each other to form an end joint, a part of the end joint is opened to provide an open portion, and the end joint is connected to the end joint. This is a three-dimensional mesh-type cleaning tool that provides a bag portion, inserts the grip portion from the open portion, inserts the grip portion into the bag portion, and integrates the grip portion with the three-dimensional mesh-type wiping body.

In the thirteenth aspect of the present invention, the grip portion is configured such that two meshing portions are elastically openable and closable, and the left and right ends of the three-dimensional mesh type wiper are meshed by the meshing portion to be engaged with the grip portion. It is a three-dimensional mesh type cleaning tool that is integrated.

According to the first aspect of the present invention, in the wiping body attached to the cleaning tool and used for wiping and cleaning, a three-dimensional cloth is used as the wiping body, and in the three-dimensional cloth, a large number of meshes are formed substantially periodically. Two mesh layers arranged in a plane are laminated via an interval layer, and the two mesh layers are arranged so that the upper mesh and the lower mesh of the same shape communicate with each other vertically. A three-dimensional mesh type wiper is provided.
The present invention is characterized in that the wiping body is composed of a three-dimensional cloth called a three-dimensional knitted fabric or a three-dimensional woven fabric. Since general woven fabrics, knitted fabrics, and non-woven fabrics are thin, it is extremely difficult to accumulate and retain dust inside the thickness of the wiping body even if it is used as a wiping body for cleaning. On the other hand, the three-dimensional fabric has an advantage that the thickness can be freely adjusted and the dust collected inside the thickness can be accumulated and held. In the prior art of using a three-dimensional fabric, as in Patent Documents 4 and 5, the focus was on utilizing the elasticity of the thickness of the three-dimensional fabric, but the present invention collects and accumulates dust in the thickness. Focusing on the feature points to be retained, the inventor of the present application has conceived the present invention by paying attention to the above-mentioned new characteristics.
In the three-dimensional fabric, two mesh layers in which a large number of meshes are arranged in a plane substantially periodically are laminated with each other separated by an interval layer, and the two mesh layers are formed with the upper mesh having the same shape as each other. The feature is that the lower mesh is arranged so as to communicate with each other up and down. The shape of the mesh is formed by weaving fibers into a ring shape (annular thread referred to below) in various shapes such as a quadrangle, a hexagon, and a circle, and the upper mesh and the lower mesh of the same shape are up and down. It is arranged so as to communicate with. Therefore, when the lower mesh is seen through from the upper mesh, there are no obstacles in the middle, and dust can be accumulated and held in this internal space.

Further, according to the first aspect of the present invention, the two annular threads forming the upper mesh and the lower mesh that are communicated vertically are connected to each other in a circumferential manner by a plurality of connecting threads to connect the connecting threads. The side surface is formed, and the spacing layer is configured to include the side surface of the connecting yarn inside, and a three-dimensional mesh is formed by the upper mesh, the lower mesh, and the side surface of the connecting yarn communicating vertically. It has characteristics.
As described above, the mesh is formed of annular yarn formed in a ring shape by fibers, and the same applies to the upper mesh and the lower mesh. Therefore, the two annular threads are arranged vertically apart from each other, and these two annular threads are connected vertically by a large number of connecting threads, and are connected in a circumferential manner by a large number of threads. That is, the entire circumference of the two annular threads separated vertically is connected by a large number of connecting threads, and the side surfaces of the connecting threads are formed by the large number of connecting threads. For example, if the annular thread is hexagonal, there are six small side surfaces, the small side surface becomes the connecting thread small side surface by the connecting thread, and the connecting thread side surface which is the entire side surface is formed by the six-sided connecting thread small side surface. Will be done.
The side surface of the connecting yarn exists between the upper mesh layer and the lower mesh layer, and the spacing layer includes the side surface of the connecting yarn inside. That is, the spacing layer is configured to include a large number of connecting yarn side surfaces that are arranged substantially periodically.
The feature is that a three-dimensional mesh is formed by the upper mesh, the lower mesh, and the side surfaces of the connecting yarns that communicate with each other in the vertical direction. The upper mesh and the lower mesh are upper and lower annular threads, and a tubular body called a three-dimensional mesh is formed by the upper and lower annular threads and the side surfaces of the connecting threads. In this three-dimensional mesh, the upper and lower annular yarns form an opening surface, and the side surface of the connecting yarn is closed at a part of the side surface by the thickness of the connecting yarn, but the connecting yarn and the connecting yarn are opened. Therefore, when the number of connecting threads is large, the side opening ratio is small, and conversely, when the number of connecting threads is small, the side opening ratio is large. In these cases, a large number of connecting threads are connected and fixed to the side surfaces at substantially equal intervals, slit-shaped minute side opening openings are formed between the connecting threads and the connecting threads, and the number of these minute side openings are added together. To form a side opening. The ratio of the area of the side opening to the total area of the side gives the side opening ratio.

Further, according to the first aspect of the present invention, the three-dimensional mesh has an internal space and has an opening surface in the upper mesh and the lower mesh, and when cleaned with the cleaning tool, the opening surface of the mesh is used. Provided is a three-dimensional mesh type wiper that collects dust and holds the dust in the internal space of the three-dimensional mesh.
As described above, in the three-dimensional mesh, the portion other than the annular thread of the upper mesh and the lower mesh is opened as an opening surface, and the upper mesh or the lower mesh is cleaned while being in contact with the surface to be cleaned. Then, dust can be collected through this opening surface. Further, the annular yarn has a closing ratio of only the thickness of the yarn, and the surface opening ratio due to the opening surface is 90% or more, so that a large amount of dust can be induced and collected.
Further, the three-dimensional mesh has an internal space, and dust can be accumulated and held in this internal space. Moreover, the side surface is a connecting thread side surface composed of a large number of connecting threads, and the side surface opening ratio can be adjusted from 0% to 100% depending on the number of connecting threads. That is, if the side surface is completely closed with a large number of connecting threads, the side surface aperture ratio becomes 0%. Further, if the number of connecting threads is completely zero, the side opening ratio becomes 100%. By controlling the number of connecting threads, the side aperture ratio can be adjusted from 0% to 100%. The side opening ratio depends on both the thickness and the number of connecting threads.

Furthermore, according to the first aspect of the present invention, when the side aperture ratio is 20% to 80%, the three-dimensional mesh type wiper of the present invention can be optimized, and an effective cleaning tool can be provided. ..
As will be described later, according to the experiment of the present inventor, it was found that the amount of dust collected is practically usable when the side opening ratio is 20% to 80%. In addition, the maximum dust collection amount was obtained when the side opening ratio was around 50% in the above experiment, but further detailed research suggests that the side opening ratio of the maximum dust collection amount may fluctuate. However, it has been found that effective side aperture ratios of 20% to 80% give important results and are more efficient when 30% to 70%.
Further, again, in the present invention, it is easy to set the surface aperture ratio to 90% or more, and compared with the prior art of Patent Documents 1 to 3, the surface aperture ratio is only 50% or less. , It can be seen that the invention of the present application provides an epoch-making cleaning tool. In addition, it has been clarified for the first time by the research of the present inventor that the amount of dust that can be accumulated and retained in the internal space of the three-dimensional network increases when the side aperture ratio is 20% to 80%, more preferably 30% to 70%. Became.

According to the second aspect of the present invention, either one of the opening surface of the upper mesh and the opening surface of the lower mesh is made a closing surface by a closing thread, and the other is left as an opening surface. It is possible to provide a three-dimensional mesh type wiping body that collects dust from the inside space, holds the dust in the internal space, and makes it difficult for the dust held in the internal space to be released from the closed surface.
When both the upper mesh and the lower mesh have an opening surface, dust collected from one opening surface may escape from the other opening surface. In that case, the amount of dust accumulated and held in the internal space will be reduced. Therefore, in the present embodiment, if the other opening surface is closed with a closing thread to form a closing surface, the dust accumulated in the internal space does not escape from the closing surface, and conversely, the amount of dust is prevented from being reduced and accumulated. It is possible to increase the amount of dust that can be held.
To close the opening surface with a closing thread, one closing thread may be placed in the center of the opening surface, may be closed with a plurality of closing threads, or may be completely blocked by a large number of closing threads. It may take various forms such as may be used. Dust includes not only particle components such as sand, but also a lot of household waste, especially a lot of lint, and a lot of dust that can be blocked by just one dust. The form of the closing thread is variable depending on the situation.

According to the third aspect of the present invention, in the wiping body attached to the cleaning tool and used for wiping and cleaning, a three-dimensional cloth is used as the wiping body, and in the three-dimensional cloth, a large number of meshes are formed substantially periodically. By laminating three or more layers of the mesh layers arranged in a plane on the surface via the interval layer, a three-dimensional network type wiper in which the interval layers exist in a laminated state of two or more layers is provided.
In this embodiment, the three-dimensional fabric is composed of a mesh layer-spacing layer-mesh layer-spacing layer-mesh layer, etc., in other words, a multiplex consisting of three or more mesh layers and two or more spacing layers. The target is a three-dimensional mesh type wiper made of the three-dimensional cloth of. In a three-dimensional knitting or three-dimensional weaving device, since it is possible to knit in multiple layers while continuously stacking, all the mesh layers can be formed with the same thickness, and all the mesh layers of the uppermost layer, the lowest layer and the intermediate layer can be formed. Has an equivalent structure.
On the other hand, in the first form, the smallest unit of three-dimensional fabric composed of a mesh layer-interval layer-mesh layer was targeted. The plurality of three-dimensional fabrics of the present embodiment may be formed by stacking two or more layers of the smallest unit of three-dimensional fabrics. In this case, since the mesh layer-spacing layer-mesh layer and the mesh layer-spacing layer-mesh layer are overlapped, the mesh layer-spacing layer-mesh layer / mesh layer-spacing layer-mesh layer ... Except for the uppermost mesh layer, the intermediate mesh layer tends to be thick like the mesh layer / mesh layer.
With the above configuration, the thickness of the three-dimensional fabric can be freely adjusted, and the amount of dust that can be stored and held inside can be increased.

Further, according to the third aspect of the present invention, the two adjacent mesh layers are arranged so that the upper mesh and the lower mesh having the same shape are communicated vertically, and the upper mesh is communicated vertically. The two annular yarns forming the mesh and the lower mesh are connected to each other in a circumferential manner by a plurality of connecting yarns to form a connecting yarn side surface, and the spacing layer includes the connecting yarn side surface inside. A constructed three-dimensional mesh type wiper is provided.
Moreover, a three-dimensional mesh is formed by the upper mesh, the lower mesh, and the side surfaces of the connecting threads that communicate vertically, and the three-dimensional mesh has an internal space and an opening surface between the upper mesh and the lower mesh. A large number of the three-dimensional meshes are arranged in one interval layer substantially periodically, and a three-dimensional mesh type wiper that holds dust in the internal space can be provided.
Since the above configuration is the same as that of the three-dimensional mesh type wiper provided in the first form, it is a person who naturally expresses the action / effect of the first form, and the description in the first form is taken into consideration. The description is omitted here.

Further, according to the third aspect of the present invention, by stacking two or more layers of the interval layers, two or more of the three-dimensional networks are laminated directly above to form an enlarged three-dimensional network, and the expanded three-dimensional network is formed. An enlarged internal space is formed in which two or more of the internal spaces are laminated in a continuous manner, and has an opening surface in the uppermost mesh and the lowermost mesh, and a large number of enlarged three-dimensional meshes are arranged substantially periodically. A three-dimensional mesh type wiping body configured in the above can be provided.
Two or more three-dimensional networks described in the first embodiment are laminated directly above to form an enlarged three-dimensional network which is a composite of two or more three-dimensional networks. Since each three-dimensional network has an internal space, an enlarged internal space in which these internal spaces are combined is formed inside the expanded three-dimensional network. Since two or more of the internal spaces without obstacles are combined in a communicative state to form the expanded internal space, there are no obstacles inside the expanded internal space.
Since there are opening surfaces in the uppermost mesh and the lowermost mesh of the enlarged internal space, respectively, a large enlarged internal space can be seen through from the opening surface of the uppermost mesh to the opening surface of the lowermost mesh. When the cleaning operation is performed by bringing the uppermost opening surface or the lowermost opening surface into contact with the surface to be cleaned, dust is collected from the opening surface and accumulated and held until the enlarged internal space is filled. Can be done. Therefore, in a cleaning tool using the three-dimensional cloth as a three-dimensional mesh type wiping body, when cleaning is performed with the cleaning tool, dust is collected from the opening surface of the enlarged three-dimensional mesh and a large amount of dust is collected in the expanded internal space of the enlarged three-dimensional mesh. It was possible to realize a three-dimensional mesh-type wiping body that can be accumulated and held in the air.

Furthermore, in the third embodiment of the present invention, the side surface of the enlarged three-dimensional mesh is composed of the side surface of the connecting thread in which the side surfaces of the connecting threads of the individual three-dimensional mesh are continuous vertically. Therefore, the enlarged three-dimensional mesh is formed from the uppermost mesh, the lowermost mesh, and the side surface of the enlarged connecting thread.
On the side surface of the enlarged connecting thread, the side opening ratio can be adjusted from 0% to 100% depending on the number of connecting threads. That is, if the side surface is completely closed with a large number of connecting threads, the side surface aperture ratio becomes 0%. Further, if the number of connecting threads is completely zero, the side opening ratio becomes 100%. By controlling the number of connecting threads, the side aperture ratio can be adjusted from 0% to 100%. The side opening ratio depends on both the thickness and the number of connecting threads.
Further, also in the third embodiment of the present invention, as in the first embodiment, when the side opening ratio of the side surface of the enlarged connecting yarn is 20% to 80%, the three-dimensional mesh type wiper of the present invention can be optimized. Effective cleaning tools can be provided. As described above, according to the experiment of the present inventor, it was found that the dust collection amount can withstand practical use when the side opening ratio is 20% to 80%. In addition, the maximum amount of dust collected was when the side opening ratio was around 50% in the above experiment. However, this value is likely to fluctuate with further detailed studies. However, it has been found that effective side aperture ratios of 20% to 80% give important results and are more efficient when 30% to 70%.
Finally, in the present invention, it is easy to set the surface aperture ratio to 90% or more, and compared with the prior art of Patent Documents 1 to 3, the surface aperture ratio is only 50% or less. Can be seen to provide a groundbreaking cleaning tool. In addition, it has been clarified for the first time by the research of the present inventor that the amount of dust that can be accumulated and retained in the internal space of the three-dimensional network increases when the side aperture ratio is 20% to 80%, more preferably 30% to 70%. Became.

According to the fourth aspect of the present invention, one of the opening surface of the mesh on the uppermost surface and the opening surface of the mesh on the lowermost surface is made a closing surface by a closing thread, and the other is left as an opening surface. It is a three-dimensional mesh type wiping body that collects dust from a surface and holds the dust in the enlarged internal space so that the dust held in the enlarged internal space is not discharged from the closed surface.
In the enlarged three-dimensional mesh, when both the uppermost mesh and the lowermost mesh have an opening surface, dust collected from one opening surface may escape from the other opening surface. In this case, the amount of dust accumulated and held in the expanded internal space is reduced. Therefore, in the present embodiment, if the other opening surface is closed with a closing thread to form a closing surface, the dust accumulated in the enlarged internal space does not escape from the closing surface, and conversely, the reduction of dust is prevented. It is possible to increase the amount of dust that can be accumulated and retained.
To close the opening surface with a closing thread, one closing thread may be placed in the center of the opening surface, may be closed with a plurality of closing threads, or may be completely blocked by a large number of closing threads. It may take various forms such as may be used. Dust includes not only particle components such as sand, but also a lot of household waste, especially a lot of lint, and a lot of dust that can be blocked by just one dust. The form of the closing thread is variable depending on the situation.

According to the fifth aspect of the present invention, it is possible to provide a three-dimensional mesh type wiper having one kind or two or more kinds of mesh shapes in the three-dimensional cloth.
As described above, the mesh layer is formed by arranging a large number of meshes in a plane in a substantially periodic manner, and the mesh is divided into a single mesh shape and a mesh having two or more mesh shapes. Be done. As the mesh shape, there are triangles, squares, hexagons, octagons, circles, and the like. The case of a single shape is a case where only one mesh shape is arranged in a plane with substantially periodicity, for example, a hexagonal shape is arranged substantially periodically as a mesh. Further, the case of two or more mesh shapes is a case in which a hexagonal shape and a round shape are arranged in a substantially periodic manner as a unit. These depend on the molding technique of the three-dimensional fabric, and any mesh shape is included in the embodiment of the present invention.

According to the sixth aspect of the present invention, the three-dimensional cloth can be provided with a three-dimensional mesh type wiper on which an adsorbent that adsorbs and holds dust is supported. Here, the adsorbent refers to an agent that adsorbs dust.
Generally, it is divided into a case where the three-dimensional cloth is impregnated with nothing to form a wiping body and a case where the three-dimensional cloth is impregnated with an adsorbent to form a wiping body. When the adsorbent is not impregnated, the cleaning is focused on entwining dust with the fibers of the three-dimensional fabric. On the other hand, when the three-dimensional cloth is impregnated with the adsorbent, the fibers of the three-dimensional cloth entangle the dust, and then the adsorbent covers the dust with a liquid film to firmly adhere and hold the dust. Therefore, in the case of the adsorbent, it has an excellent performance of accumulating and retaining dust.
The adsorbent is divided into an aqueous adsorbent and an oil-based adsorbent. The aqueous adsorbent is an adsorbent mainly composed of an aqueous solution, and the oil-based adsorbent is an adsorbent mainly composed of an oil agent. Cleaning can be performed efficiently by using different adsorbents.

According to the seventh aspect of the present invention, it is possible to provide a three-dimensional mesh type wiper in which the three-dimensional cloth is charged with a fixed charge or static electricity.
Generally, dust is positively or negatively charged and scattered. In other words, the dust repels each other due to the same electricity and does not bond with each other, and is scattered on the surface to be cleaned without forming a dumpling. Therefore, if the three-dimensional fabric is charged with static electricity or a fixed charge, the dust can be electrically attracted and strongly collected. However, since static electricity moves around, it is difficult to stably fix it in a stationary state. Therefore, if ions are driven into a resin fiber or the like with a high electric field, electricity can be fixed to the resin fiber, which is called a fixed charge.
That is, if the three-dimensional cloth is charged with static electricity or a fixed charge, the dust can be collected in the three-dimensional mesh by the electric attraction, and the dust can be accumulated and held in the internal space or the expanded internal space.

According to the eighth aspect of the present invention, as the wiping body, a three-dimensional mesh type wiping body in which the three-dimensional cloth is combined with a wiping material for cleaning other than the three-dimensional cloth can be provided.
There are two types of three-dimensional cloth type wipes used in the present invention. The first is a wiping body formed only from a three-dimensional cloth, which is used as a wiping body by molding only the three-dimensional cloth into a predetermined shape. The second is a wiping body in which a cleaning wiping material other than the three-dimensional cloth is combined with the three-dimensional cloth. A three-dimensional cloth type wiper having a composite form in which a pile is combined with a three-dimensional cloth, a wiping paper is combined with a three-dimensional cloth, a normal cloth is combined with a three-dimensional cloth, and a pile and a normal cloth are combined with a three-dimensional cloth. be. There are innumerable such composite type three-dimensional cloth type wipes, and there are various combinations depending on the place to be cleaned and the cleaning method.
As described above, the optimum three-dimensional cloth type wiper can be constructed by devising various composite forms and combination forms.

According to the ninth aspect of the present invention, the three-dimensional mesh type wiping body according to any one of the first to eighth forms is used, and the grip portion to which the three-dimensional mesh type wiping body is mounted is connected to the grip portion. When the three-dimensional mesh type wiping body is brought into contact with the surface to be cleaned for cleaning, dust is collected from the surface to be cleaned through the opening surface of the mesh, and the internal space of the three-dimensional mesh or the expansion of the three-dimensional mesh. It is possible to provide a three-dimensional mesh type cleaning tool that holds dust in the enlarged internal space of the three-dimensional mesh.
The present embodiment relates to a cleaning tool in which a three-dimensional mesh type wiping body formed of a three-dimensional cloth is attached to the tip of a handle portion and used as a mop. It is composed of a handle part and a grip part, and if a three-dimensional mesh type wiper is attached to the grip part and the three-dimensional mesh type wiper is brought into contact with the surface to be cleaned and the handle is operated, dust is collected and caught from the opening surface. The collected dust is accumulated and held in the internal space of the three-dimensional network or the expanded internal space of the expanded three-dimensional network. Further, even if the handle portion is shaken slightly, the dust does not fall and is stored in the internal space or the enlarged internal space.

According to the tenth aspect of the present invention, the grip portion is made of a substrate, and the central portion of the wiping body of the three-dimensional mesh type wiping body is arranged so as to be in contact with the cleaning side surface of the grip portion.

That is, if a rectangular three-dimensional mesh wiper is placed on the floor, a substrate is placed in the center thereof, and both ends of the three-dimensional mesh wiper are fixed to the front side surface of the substrate, it can be used as a cleaning tool. .. If the cleaning side surface of the grip portion is pressed against the surface to be cleaned and pushed and pulled, dust is collected from the surface to be cleaned through the opening surface, and the collected dust is collected in the internal space of the three-dimensional mesh or the expanded internal space of the enlarged three-dimensional mesh. It is accumulated and retained in. Further, even if the handle is shaken a little, the dust does not fall and is stored in the internal space or the enlarged internal space.

According to the eleventh embodiment of the present invention, the three-dimensional mesh type wiping body has a curved portion folded back in a curved shape, and its left and right ends are connected to the grip portion, and the inside of the curved portion is inside. A three-dimensional mesh type cleaning tool is provided in which a space portion is formed and the curved portion is pressed against a surface to be cleaned for cleaning.
This form is limited to the special form in which the three-dimensional mesh type wiping body is formed into a bag in a curved shape below the grip portion in the eighth form. For example, if the three-dimensional mesh type wiper is bent into a U shape, a curved portion is formed, and if the left and right ends thereof are connected to the grip portion, a cleaning tool in which a large space portion is formed in the curved portion is completed. Will be done. When the curved part is pushed and pulled while pressing against the surface to be cleaned to clean it, and when the surface to be cleaned is swept and cleaned by the curved part, dust is collected from the surface to be cleaned through the opening surface, and the collected dust is a three-dimensional mesh. It is accumulated and held in the internal space or the expanded internal space of the expanded three-dimensional network. Even if the handle is shaken a little, the dust does not fall and is stored in the internal space or the enlarged internal space. It also has the advantage that dust that has escaped from the internal space or the enlarged internal space falls and accumulates in the space inside the curved portion.

Hereinafter, embodiments of the three-dimensional mesh-type wiping body 30 and the three-dimensional mesh-type cleaning tool 1 according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is an overall perspective view illustrating Example 1 of a three-dimensional mesh-type cleaning tool 1 using the three-dimensional mesh-type wiping body 30 according to the present invention.
Broadly speaking, the three-dimensional mesh type cleaning tool 1 is composed of a handle portion 10, a grip portion 20 provided at the tip thereof, and a three-dimensional mesh type wiping body 30 supported by the grip portion 20.

The handle portion 10 includes a grip 12 that can be grasped by hand and a long-axis handle body 10a. The grip portion 20 is a rod-shaped body, and is composed of a grip portion central portion 21, a grip portion projecting portions 23 and 24 projecting to the left and right thereof, and a veneer 22. The veneer 22 is connected to the handle receiver 13 by a button shaft 14, and the handle receiver 13 is configured to be rotatable left and right with the button shaft 14 as a fulcrum. Further, the tip of the handle body 10a is inserted into the handle receiver 13, and the handle portion 10 and the grip portion 20 are integrated. Therefore, the handle portion 10 can rotate left and right with respect to the grip portion 20 with the button shaft 14 as a fulcrum. When the left and right gripped portion protrusions 23 and 24 are unlocked, they can be bent freely at both ends of the gripped portion central portion 21, and in a free state, they hang down due to gravity and can swing left and right. Further, when the left and right grip portion protruding portions 23 and 24 are placed in a horizontal state in parallel with the grip portion central portion 21, they are locked and held in a horizontal state as shown in FIG.

In the three-dimensional mesh type wiping body 30, the rectangular three-dimensional cloth 31 is folded back at the center to form a curved portion 38 at the center, and the left and right end portions 34a and 34a thereof are joined to form an end joining portion 34. Various bonds such as fusion and sewing are used for bonding. Further, an uncoupled open portion 33 is provided at the center of the end joint portion 34. Further, the dividing member 35 is provided at a position separated from the end connecting portion 34 by a predetermined distance to the full width of the three-dimensional fabric 31, and the bag portion 36 is placed between the end connecting portion 34 and the dividing member 35 of the three-dimensional fabric 31. It is provided to the full width. Further, inside the curved portion 38, a space portion 37 is provided below the dividing member 35.

The following procedure is performed in order to insert the grip portion 20 of the handle portion 10 into the bag portion 36. First, before inserting the handle portion 10, the left and right grip portion protrusions 23 and 24 are unlocked and hung downward. The left and right grip portion protrusions 23 and 24 hang down in a swinging state, and the left and right grip portion protrusions 23 and 24 are simultaneously inserted into the bag portion 36 in this swinging hanging state. Of course, you may insert one by one. When inserted, the left and right gripped portion protrusions 23 and 24 are locked in a horizontal state. In this way, the grip portion 20 is integrated with the three-dimensional mesh type wiping body 30.

As described above, the three-dimensional mesh type wiping body 30 is formed of the three-dimensional cloth 31. The structure of the three-dimensional fabric 31 is shown in FIG. 1 surrounded by a dashed line. That is, the three-dimensional cloth 31 is formed by spreading the three-dimensional cloth structure 31a surrounded by the alternate long and short dash line over the entire surface. The three-dimensional cloth 31 is a towel-like cloth such as a woven fabric or a knitted fabric, but is different from a towel in that it has a considerable thickness and has a shrinkage performance in the thickness direction. In the industry, it is called a three-dimensional woven fabric or a three-dimensional knit, but in the present application, it is referred to as a three-dimensional fabric 31 as a broad concept including both. The three-dimensional fabric 31 is formed by arranging innumerable three-dimensional meshes 32 in a plane substantially periodically, and exhibits a shrinkage performance based on the characteristics of the three-dimensional mesh 32. The detailed structure will be described later.

In order to clean the surface to be cleaned 60 indicated by the alternate long and short dash line using the three-dimensional mesh type cleaning tool 1 of the first embodiment, the lowermost end portion of the curved portion 38 is brought into contact with the surface to be cleaned 60, and the handle portion 10 is held by both hands. Just grab it with and sweep it. Since the surface aperture ratio of the opening surface of the three-dimensional mesh 32, that is, the ratio of the total area of the opening surface to the total area of the surface of the three-dimensional mesh 32 is as large as 90% or more, the dust collection efficiency of the dust 62 is extremely high. Therefore, the dust on the surface to be cleaned 60 is highly efficiently collected from the opening surface 43 on the surface of a large number of three-dimensional meshes 32 on the curved portion 38. The collected dust 62 is surely accumulated and held inside the three-dimensional mesh 32. As will be described later, a large number of connecting threads 45 are present on the side surface of the three-dimensional mesh 32, and dust 62 is not discharged from the three-dimensional mesh 32 to the side surface side. Further, when the back of the three-dimensional mesh 32 is the opening surface 43, even if the dust 62 is discharged, the dust 62 is held in the space 37 inside the three-dimensional mesh type wiping body 30, so that the surface to be cleaned It is not discharged to 60. Further, when the back of the three-dimensional mesh 32 is closed, the dust 62 cannot escape from the three-dimensional mesh 32, and the function of holding the dust 62 reaches the maximum efficiency.

FIG. 2 is an overall perspective view illustrating Example 2 of the three-dimensional mesh-type cleaning tool 1 using the three-dimensional mesh-type wiping body 30 according to the present invention.
In the second embodiment, the handle portion 10 is composed of the handle body 10a and the grip 12, and the grip portion 20 is composed of a substrate. Although not shown, a pair of veneers are projected on the upper surface of the grip portion 20, the tip of the handle body 10a is inserted between the pair of veneers, and the handle portion 10 is connected to the veneers by the button shaft 14. It is rotatably provided around the button shaft 14.

The three-dimensional mesh type wiping body 30 is formed by cutting the three-dimensional cloth 31 into a rectangular shape, and the central portion of the three-dimensional mesh type wiping body 30 is brought into contact with the cleaning side surface 25 of the grip portion 20, and the left and right sides of the three-dimensional cloth 31 are formed. The ends 34a and 34a are curved so as to surface on the non-cleaning side surface 26 of the grip portion 20 and fixed by means such as a hook-and-loop fastener.
As described above, the three-dimensional mesh type wiping body 30 is formed of the three-dimensional cloth 31, and a part of the three-dimensional cloth 31 is shown as a three-dimensional cloth structure 31a surrounded by a chain line. Similar to the above, the three-dimensional cloth 31 is formed by spreading the three-dimensional cloth structure 31a surrounded by the alternate long and short dash line over the entire surface. The three-dimensional fabric 31 has a large thickness and has a shrinkage performance in the thickness direction. The three-dimensional fabric 31 is formed by arranging innumerable three-dimensional meshes 32 in a plane in a substantially periodic manner, and exhibits a shrinkage performance based on the characteristics of the three-dimensional mesh 32. The detailed structure will be described later.

In order to clean the surface to be cleaned 60 indicated by the alternate long and short dash line using the three-dimensional mesh type cleaning tool 1 of the second embodiment, the center of the three-dimensional mesh type wiping body 30 on the cleaning side surface 25 of the grip portion 20 is the surface to be cleaned. All that is required is to bring the handle portion 20 into surface contact with the 60 and push and pull the handle portion 20.
As described above, the surface aperture ratio of the opening surface 43 of the three-dimensional mesh 32, that is, the ratio of the total area of the opening surface 43 to the total area of the surface of the three-dimensional network 32 is as large as 90% or more, and therefore the dust 62 is trapped. The collection efficiency is extremely high. The reason for this is that in the three-dimensional mesh 32, all the regions other than the mesh yarn forming the mesh are open, so that the surface coverage ratio of the mesh yarn is as small as 10% or less, and as a result, the surface aperture ratio is 90% or more. Because it becomes. Therefore, the dust 62 on the surface to be cleaned 60 is highly efficiently collected from the opening surface 43 on the surface of a large number of three-dimensional meshes 32 on the curved portion 38.
The collected dust is surely accumulated and held inside the three-dimensional mesh 32. As will be described later, a large number of connecting threads 45 are present on the side surface of the three-dimensional mesh 32, and dust is not discharged from the three-dimensional mesh 32 to the side surface side. Further, since the back of the three-dimensional mesh 32 is closed by the surface of the grip portion 20, the dust 62 does not escape from the three-dimensional mesh 32. Therefore, the function of accumulating and retaining the dust 62 reaches maximum efficiency.

FIG. 3 is a perspective view of a three-dimensional cloth structure 31a in which the three-dimensional mesh type wiping body 30 according to the present invention is composed of a one-layer type three-dimensional cloth 31 composed of a mesh layer, an interval layer, and a mesh layer.
In the three-dimensional cloth structure 31a of the three-dimensional mesh-type wiping body 30, a mesh layer 40 in which a large number of meshes 41 are arranged in a plane substantially periodically is laminated in two layers via an interval layer 42, and the two-layer mesh layer is laminated. 40 and 40 are arranged so that the upper mesh 41a and the lower mesh 41b, which have the same shape as each other, communicate with each other vertically. The two annular threads 44, 44 forming the upper mesh 41a and the lower mesh 41b communicating vertically are connected to each other in a circumferential manner by a plurality of connecting threads 45 to form a connecting thread side surface 46. .. The spacing layer 42 is configured to include the connecting yarn side surface 46 inside.
A three-dimensional mesh 32 is formed by an upper mesh 41a, a lower mesh 41b, and a connecting thread side surface 46 that communicate vertically, and the three-dimensional mesh 32 has an internal space 47 and is formed in the upper mesh 41a and the lower mesh 41b. It has openings 43, 43. In other words, when the upper annular thread 44 and the lower annular thread 44 are connected by a large number of connecting threads 45 to form the connecting thread side surface 46, the upper and lower annular threads 44 and the connecting thread side surface 46 form a tubular body, that is, When the three-dimensional mesh 32 is formed and the tubular bodies are arranged side by side in a plane substantially periodically, the thick layer excluding the upper and lower annular threads 44 and 44 becomes the interval layer 42. The inside of the three-dimensional mesh 32, which is a tubular body, is a complete space and becomes an internal space 47.

When the surface to be cleaned 60 is cleaned with the three-dimensional mesh type cleaning tool 1, dust 62 can be efficiently collected from the opening surface 43 of the mesh 41. The reason is that the surface aperture ratio of the opening surface 43 of the three-dimensional mesh 32, that is, the ratio of the total area of the opening surface 43 to the total area of the surface of the three-dimensional mesh 32 is extremely large at 90% or more, so that dust 62 is collected. The efficiency is extremely high. The reason for this is that in the three-dimensional mesh 32, all the regions other than the annular yarn 44 forming the mesh are open, and the surface coverage ratio of the annular yarn 44 is as small as 10% or less, and as a result, the surface aperture ratio is 90% or more. Because it becomes.
Further, the dust 62 collected in the three-dimensional mesh 32 is accumulated in the internal space 47 of the three-dimensional mesh 32 and cannot escape from the internal space 47. The reason is that the collected dust 62 cannot escape because it is blocked by a large number of connecting threads 45 even if it tries to escape from the side surface 46 of the connecting threads, and is held in the internal space 47.
More specifically, when the side opening ratio is adjusted from 0% to 100% according to the number of connecting threads 45 and tested, dust 62 accumulates in the internal space 47 when the side opening ratio is 20% to 80%. It was found that the three-dimensional mesh type wiping body 30 of the present invention can be optimized and an effective cleaning tool can be provided. The maximum dust collection rate is considered to be 40% to 60%, which varies depending on the conditions, although the side opening ratio was about 50% in the experiment described later. Considering the variability of the maximum point of the dust collection rate, it is considered that a side opening ratio of 20% to 80% is advantageous, and a side opening ratio of 30% to 70% is more efficient.

FIG. 4 is a perspective view of a three-dimensional cloth structure 31a in which the three-dimensional mesh type wiping body 30 according to the present invention is composed of a two-layer type three-dimensional cloth 31 composed of a mesh layer-spacing layer-mesh layer-spacing layer-mesh layer. ..
In the three-dimensional fabric structure 31a, three or more mesh layers 40 in which a large number of meshes 41 are arranged in a plane substantially periodically are laminated via an interval layer 42, so that the interval layers 42 exist in a laminated state of two or more layers. doing. The two adjacent mesh layers 40, 40 are arranged so that the upper mesh 41a and the lower mesh 41b, which have the same shape as each other, communicate with each other vertically.
The upper mesh 41a and the two annular threads 44, 44 forming the lower mesh 41b, which communicate with each other in the vertical direction, are connected to each other in a circumferential manner by a plurality of connecting threads 45 to form a connecting thread side surface 46. The spacing layer 42 is configured to include the connecting thread side surface 46 inside, and a three-dimensional network 32 is formed by an upper mesh 41a, a lower mesh 41b, and a connecting thread side surface 46 that communicate vertically.
The three-dimensional mesh 32 has an internal space 47, and has an opening surface 43 in the upper mesh 41a and the lower mesh 41b.

In one spacing layer 42, a large number of the three-dimensional meshes 32 are arranged substantially periodically, and by stacking two or more layers of the spacing layers 42, two or more of the three-dimensional meshes 32 are laminated directly above. The enlarged three-dimensional network 50 is formed. In the enlarged three-dimensional mesh 50, two or more of the internal spaces 47 are laminated in a continuous manner to form an enlarged internal space 52, and the uppermost mesh 51a and the lowermost mesh 51b have opening surfaces 43. A large number of enlarged three-dimensional networks 50 are arranged in a substantially periodic manner.
When the three-dimensional cloth 31 is cleaned with the three-dimensional mesh type cleaning tool 1 in which the three-dimensional cloth 31 is laminated in multiple layers, dust 62 is collected from the opening surface 43 of the enlarged three-dimensional mesh 50 and dust 62 is collected in the expanded internal space 52 of the enlarged three-dimensional mesh 50. It can be collected, accumulated and retained.

Even if the surface to be cleaned 60 is cleaned with the multi-layered three-dimensional mesh type cleaning tool 1, dust 62 can be efficiently collected from the opening surface 43 of the uppermost mesh 51a or the lowermost mesh 51b. The reason is the same as that of the one-layer three-dimensional mesh type cleaning tool 1, and the surface aperture ratio of the opening surface 43 of the three-dimensional mesh 32, that is, the ratio of the total area of the opening surface 43 to the total area of the surface of the three-dimensional mesh 32 is This is because the collection efficiency of the dust 62 is extremely high because it is extremely large at 90% or more.
Further, the dust 62 collected in the expanded three-dimensional network 50 is accumulated in a large amount in the expanded internal space 52 of the expanded three-dimensional network 50 and cannot escape from the expanded internal space 52. The reason is that the collected dust 62 is blocked by a large number of connecting threads 45 on the side surface 46 of the connecting threads and cannot escape, and is held in the expanded internal space 52.
Even in this multi-layer three-dimensional mesh type cleaning tool 1, when the side opening ratio is 20% to 80%, the accumulation and retention of dust 62 in the internal space 47 becomes efficient, and when the side opening ratio is 30% to 70%. It is considered to be more efficient.

FIG. 5 is a perspective view of a three-dimensional cloth structure 31a in which the three-dimensional mesh type wiping body 30 according to the present invention is composed of a one-layer type three-dimensional cloth 31 composed of a mesh layer, a thick interval layer, and a mesh layer.
The three-dimensional mesh type wiping body 30 has exactly the same other features except that the length of the connecting thread 45 is longer than that in FIG. That is, it can be said that the spacing layer 42 is only thick, and the configuration, action, and effect of the three-dimensional mesh type wiping body 30 of FIG. 3 are almost the same.
In order to increase the thickness of the spacing layer 42, the multi-layer type may be used as shown in FIG. 4, or the length of the connecting thread 45 may be increased as shown in FIG. In either method, the action and effect are the same, and further description will be omitted in the case of 茲.

FIG. 6 is a partial plan view of the three-dimensional cloth 31 showing various mesh shapes such as a square, a hexagon, a circle, and an ellipse in the three-dimensional mesh type wiping body 30 according to the present invention.
In (6A), a three-dimensional cloth 31 composed of a large number of hexagonal meshes 41 is shown. In (6B), a three-dimensional cloth 31 composed of a large number of square meshes 41 is shown. In (6C), a three-dimensional cloth 31 composed of a large number of meshes 41 having two types of shapes, a small ellipse and a great ellipse, is shown. As described above, as the three-dimensional fabric 31, not only a single shape but also a plurality of shapes of meshes 41 can be arranged in a plane substantially periodically to form a wide variety of three-dimensional fabrics 31, and these three-dimensional fabrics 31 can be formed. It can be used in the present invention.

FIG. 7 is a structural perspective view illustrating an assembly structure of a plurality of three-dimensional meshes 32 in the three-dimensional mesh type wiping body 30 according to the present invention.
The three-dimensional mesh wiping body 30 is formed of a three-dimensional cloth 31 having a three-dimensional cloth structure 31a. The three-dimensional fabric structure 31a is three-dimensionally configured by laminating the upper mesh layer 40 and the lower mesh layer 40 and connecting the upper and lower mesh layers 40 and 40 with a large number of connecting threads 45.
More specifically, the upper and lower mesh layers 40 and 40 have the same structure, and are formed on a plane from fibers in the vertical and horizontal directions by weaving or knitting, and a large number of meshes 41 have a substantially periodic period. It is configured so that it is arranged in a plane. The minimum unit is a mesh 41, which is divided into a ring shape by an annular thread 44, and is composed of an annular thread 44, 44 having the same shape as the upper mesh 41a and the lower mesh 41b.

The upper annular thread 44 and the lower annular thread 44 are connected to all side surfaces by a large number of connecting threads 45 at substantially equal intervals, and the intervals between the upper and lower annular threads 44, 44 are the thickness of the interval layer 42. become. Due to the presence of these large number of connecting threads 45, the upper and lower mesh layers 40, 40 have elasticity and have a function of immediately returning to the original thickness even when compressed.
Unobtrusive opening surfaces 43 and 43 are opened in the upper and lower meshes 41a and 41b. The upper and lower annular threads 44, 44 and the connecting thread side surface 46 are formed in a cylindrical body, and a hollow internal space 47 exists inside the tubular body. This tubular body is referred to as a three-dimensional mesh 32, and the three-dimensional cloth structure 31a is a structure in which the three-dimensional mesh 32 is arranged in a plane substantially periodically.

The three-dimensional mesh 32 has an opening surface 43 opened in each of the upper and lower meshes 41a and 41b. Since the area of the opening surface 43 is smaller than the area of the mesh 41 by the thickness area of the annular yarn 44, the ratio of the area of the opening surface 43 to the area of the mesh 41, that is, the opening ratio (also referred to as the surface opening ratio) is 90%. It is clear that this is the case. Therefore, during cleaning, the dust 62 is easily collected from the wide opening surface 43 into the internal space 47.
Further, the side surface of the three-dimensional mesh 32 is a connecting thread side surface 46 partially closed by the connecting thread 45. Even if the dust 62 accumulated in the internal space 47 by the collection tries to escape from the side surface 46 of the connecting thread, it is obstructed by the connecting thread 45 and is prevented from being released to the outside. The area obtained by subtracting the thickness area of the connecting thread 45 from the total area of the side surface is the side surface opening area, and in the present specification, the ratio of the side surface opening area to the side surface area is referred to as the side surface aperture ratio. The distribution of the collected mass of the dust 62 accumulated and held in the internal space 47 with respect to the side aperture ratio is called the dust collecting performance. According to the research of the inventor of the present application, the dust collection performance can be put into practical use when the side opening ratio is 20% to 80%, and the dust collection performance is improved when the side opening ratio is in the range of 30% to 70%. It was revealed that it could be improved.

FIG. 8 is a mechanical perspective view illustrating a mechanism for collecting, accumulating, and holding dust 62 by a plurality of three-dimensional meshes 32 in the three-dimensional mesh type wiping body 30 according to the present invention.
The dust 62 on the surface to be cleaned 60 is cleaned using the three-dimensional mesh type cleaning tool 1 of the present application. When the three-dimensional mesh type wiping body 30 is brought into contact with the surface to be cleaned 60 and pushed and pulled in the arrow XX direction and the arrow YY direction, the dust 62 on the surface to be cleaned 60 has the lower mesh 41 on the surface to be cleaned. At the timing of floating from 60, it is collected from the opening surface 43 of the lower mesh 41b in the direction of arrow A to the internal space 47. Upon entering the internal space 47, the dust 62 is entangled with a large number of connecting threads 45 forming the side surface 46 of the connecting threads, and is also entangled with the upper and lower annular threads 44, 44. Due to this entanglement, the dust 62 cannot escape from the internal space 47 to the outside, and is accumulated and held in the internal space 47.

FIG. 9 is a structural perspective view illustrating the structure of one three-dimensional mesh 32 having an opening surface 43 or a closing surface 49 on the outlet side in the three-dimensional mesh type wiping body 30 according to the present invention.
(9A) is a schematic perspective view of one three-dimensional mesh 32 having the outlet side, that is, the upper mesh 41a as the opening surface 43. Of course, it is natural that the lower mesh 41b is an opening surface 43 for collecting dust in order to introduce the dust 62 from the direction of arrow A. The three-dimensional mesh 32 is composed of upper and lower annular threads 44, 44 and a connecting thread side surface 46, but the connecting thread 45 is omitted so that the front side, which is a part of the connecting thread side surface 46, can be easily seen and seen through.
(9B) is a schematic perspective view of one three-dimensional mesh 32 in which the outlet side, that is, the upper mesh 41a is closed by the closing thread 48 as the closing surface 49. The difference from (9A) is that the exit side is the closed surface 49, and other matters are exactly the same as (9A). Of course, it is natural that the lower mesh 41b is an opening surface 43 for collecting dust in order to introduce the dust 62 from the direction of arrow A. The three-dimensional mesh 32 is composed of upper and lower annular threads 44, 44 and a connecting thread side surface 46, but the connecting thread 45 is omitted so that the front side, which is a part of the connecting thread side surface 46, can be easily seen and seen through.

FIG. 10 is a structural perspective view illustrating the structure of a two-layer type enlarged three-dimensional mesh 50 having an opening surface 43 on the outlet side in the three-dimensional mesh type wiping body 30 according to the present invention.
The upper three-dimensional mesh 32 is formed by surrounding the upper and lower annular threads 44, 44 with the connecting thread side surfaces 46 so as to have an internal space 47, and similarly, the lower three-dimensional mesh 32 also has the upper and lower annular threads 44, 44. Is surrounded by the side surface 46 of the connecting thread and is formed so as to have an internal space 47 inside.
Two layers of these two three-dimensional networks 32, 32 are laminated to form an enlarged three-dimensional network 50, and an enlarged internal space 52 in which two internal spaces 47, 47 are laminated is formed inside the enlarged three-dimensional network 50. The upper connecting thread side surface 46 and the lower connecting thread side surface 46 are both configured by arranging a large number of connecting threads 45 connected vertically in a circumferential shape, and these two connecting thread side surfaces 46, 46 form an enlarged three-dimensional network 50. Sides are constructed.
It is natural that the mesh 51b on the lowermost surface is an opening surface 43 for collecting dust in order to introduce the dust 62 from the direction of arrow A. In this figure, the mesh 51a on the uppermost surface also has an opening surface 43, and the collected dust 62 is accumulated and held in the enlarged internal space 52, and the dust 62 escaping from the opening surface 43 on the uppermost surface is relatively small. I know. The reason is that the dust 62 that has entered the expanded internal space 52 is entangled with a large number of connecting threads 45 on the side surface 46 of the connecting threads, and has an action of being strongly held in the expanded internal space 52.

FIG. 11 is a structural perspective view illustrating the structure of the two-layer type enlarged three-dimensional mesh 50 having the outlet side as the closing surface 49 in the three-dimensional mesh type wiping body 30 according to the present invention.
In FIG. 10, the outlet side is the opening surface 43, whereas in FIG. 11, the exit side is the closing surface 49 due to the closing thread 48. Even in the structure of FIG. 10 in which the outlet side is the opening surface 43, it is difficult for the dust 62 to escape from the opening surface 43 on the outlet side. The escape of the dust 62 can be completely blocked.
Regarding other matters, FIGS. 10 and 11 are the same, and the matters already described in FIG. 10 are omitted from being repeatedly described here by quoting them.

FIG. 12 is a test photographic diagram for testing the cleaning performance of the floor surface using Examples 1 and 2 of the three-dimensional mesh type cleaning tool 1 according to the present invention.
The first embodiment is the three-dimensional mesh type cleaning tool 1 shown in FIG. 1, and the second embodiment is the three-dimensional mesh type cleaning tool 1 shown in FIG. In this test, the dust removal performance was compared between the mop of Example 1 not carrying the adsorbent for collecting dust, and the mops of Example 1 and Example 2 carrying the adsorbent for collecting dust. As dust, 5 g of cut cotton cut to a length of 0.1 mm was sprayed on the floor surface in an area range of about 0.32 m2 (W700 mm × D450 mm) using a 500 μm mesh sieve. Observe the remaining wiping streaks after one forward wiping (push) with the above three types of mops in the upper photo, and after this observation, carefully wipe the entire spray surface to complete dust. The removability was observed in the lower photograph.
Judging from the results of the photographs, it was found that all three types of mops were able to push and pull dust almost completely, with no traces of one-push wiping streaks. In careful wiping, it was found that in Example 1 without the adsorbent, a small amount of dust remained, and in Example 1 with the adsorbent and Example 2 with the adsorbent, the dust could be completely collected. In other words, in Example 1, since there is no adsorbent, a small amount of dust remains even after careful wiping, but if an adsorbent is supported, the dust can be completely collected by careful wiping. From the above results, in the three-dimensional mesh type cleaning tool 1 in which the adsorbent is carried on the three-dimensional mesh type wiping body 30 of the present application, the dust is pushed and pulled well, and the dust is almost completely removed from the floor surface by careful wiping. It has been demonstrated that it can collect and retain dust in the mop.

FIG. 13 is a comparative test photographic diagram in which a mop manufactured by A company and mops 1 and 2 manufactured by B company are used to perform a comparative test on the cleaning performance of the surface to be cleaned.
In the test of FIG. 13, exactly the same test as the test of FIG. 12 was performed. The test objects are three types of conventional mops, mops made by company A and mops 1 and 2 made by company B, which are marketed by other companies different from the applicant, and all of them carry mops made by other companies. Is. In exactly the same manner as in FIG. 12, 5 g of cut cotton cut to a length of 0.1 mm as dust was sprayed on the floor surface having an area range of about 0.32 m2 (W700 mm × D450 mm) using a 500 μm mesh sieve.
Judging from the results of the photographs, it was found that all three types of conventional mops can push and pull dust almost completely because no residue of the wiping streaks was found. However, careful wiping made a big difference. It was found that a small amount of dust remained in the mop manufactured by A company, some dust remained in the mop 2 manufactured by B company, and a large amount of dust remained in the mop 1 manufactured by B company.
From these facts, it can be seen that in the conventional mop, even if the floor surface is thoroughly wiped by supporting the adsorbent, if the amount of dust increases, some dust remains on the floor surface.
On the other hand, according to the three-dimensional mesh type wiping body 30 of the present application, dust can be almost completely collected from the floor surface by supporting the adsorbent, and the three-dimensional mesh type wiping body 30 and the three-dimensional mesh type cleaning tool 1 of the present application can be drawn. It was found that a phased effect can be exhibited.

FIG. 14 shows that after collecting dust from the surface to be cleaned 60 using the first embodiment of the three-dimensional mesh type cleaning tool 1 according to the present invention, the collected dust is sucked and removed by another dust suction device. It is a test photograph figure of the removal performance which purifies a three-dimensional mesh type wiping body 30.
The upper left photograph is a photograph of black dust collected on the three-dimensional mesh-type wiper 30 from the floor surface using the mop of Example 1 with an adsorbent, and the black dust is collected on the surface of the three-dimensional mesh-type wiper 30. It is confirmed that is attached and darkened. The device facing in front of the wiping body is a dust suction device that sucks and removes dust from the three-dimensional mesh type wiping body 30. The lower left photograph is a photograph of the three-dimensional mesh type wiper 30 after sucking and removing black dust from the darkened three-dimensional mesh type wiper 30 with a dust suction device, and the black dust is almost completely removed. I understand.
The upper right photograph is a photograph of white dust (cut cotton cut into 0.1 mm) collected on a three-dimensional mesh type wiping body 30 from the floor surface using the mop of Example 1 with an adsorbent. It is confirmed that white dust adheres to the surface of the three-dimensional mesh type wiping body 30 and becomes white. The lower right photograph is a photograph of the three-dimensional mesh type wiper 30 after suction and removal of white dust from the whitened three-dimensional mesh type wiper 30 with the same dust suction device, and the white dust is almost completely removed. You can see that there is.
From the above, it was found that the black dust and white dust collected in the three-dimensional mesh type wiping body 30 can be almost completely removed by the dust suction device and can be cleaned to the original state. The reason is that the internal space 47 and the expanded internal space 52 where the dust is accumulated and held are very easy for air to flow, so that the dust can be easily sucked and removed.

FIG. 15 is a comparative test photographic diagram of the performance of removing dust from the surface to be cleaned 60 by the three-dimensional mesh type wiper 30 (with adsorbent) and the other three types of wiper (with adsorbent) according to the present invention. ..
The present invention is labeled as a three-dimensional mesh, and is a multiple-wound three-dimensional fabric (manufactured by PA / PET). The first of the other three types of wipes is a three-dimensional rigid frame structural material (made of olefin elastomer) that is often used as a cushioning material for beds (bedding), and the second is a net (made of PET) that is wound multiple times. The third is a sponge (made of polyurethane). The same adsorbent is supported on these four types of wipers.
The test photograph in the middle row is a photograph of the remaining wiping streaks on the floor surface after pushing the dust scattered on the floor surface. Of the four types, only the three-dimensional rigid frame structural material has some wiping streaks remaining, but the other three types do not have wiping streaks remaining, indicating that they have the same level of pushing and pulling performance. Here, as dust, 3 g of cut cotton cut to a length of 0.1 mm is sprayed on the floor surface in an area range of about 0.32 m2 (W700 mm × D450 mm) using a 500 μm mesh sieve. ..
The lower test photograph is a photograph of whether or not the dust can be completely removed by thoroughly wiping the entire spraying surface after the above-mentioned push. Only the three-dimensional mesh 32 of the present application shows the complete removal property of dust. A small amount remains in the three-dimensional rigid frame structure, but a considerable amount remains in the net and sponge. The evaluation is indicated by good (○), acceptable (Δ), and unacceptable (×).
From the above, it can be seen that only the three-dimensional mesh type wiping body 30 of the present application has no wiping streaks left by one push and shows perfection in the retention of 3 g of cotton powder.

[Relationship between side aperture ratio and collected mass of 11 samples]
FIG. 16 is a photographic view of a simulated three-dimensional mesh produced by using a 3D printer for the three-dimensional mesh 32 of the three-dimensional mesh type wiping body 30 according to the present invention in order to perform a performance test for collecting cut cotton as dust. The inventor of the present application produced a rectangular parallelepiped having a size of 10 mm × 5 mm × 5 mm and a hollow inside with a 3D printer as a simulated product of the three-dimensional mesh 32. The upper and lower opening surfaces 43 were set to 10 mm × 5 mm and completely opened, and the connecting thread 45 indicated by the vertical line on the side surface indicated by the vertical line was manufactured by a 3D printer.
Two photographs of the two three-dimensional meshes 32 actually produced are shown. There are two side surfaces of 10 mm × 5 mm and 5 mm × 5 mm, and only a plurality of pillars corresponding to the connecting thread 45 are erected on the side surface. The thickness of the pillar is 0.5 mm. On the side of 10 mm x 5 mm, the total area is 50
If it is mm2 and the number of pillars is h, the opening area of the side surface is 50- (5 mm × 0.5 mm × h) = 50-2.5 h (mm2). Therefore, the aperture ratio of the side surface is given by (50-2.5 h) / 50 × 100 (%) = 100-5 h (%). Eleven cases of h = 0, 2, 4, 6, 8, 10, 12, 14, 16, 18, and 20 were produced.
At the same time, on the side surface of 5 mm × 5 mm, the total area is 25 mm2, and if the number of pillars is k, the opening area of the side surface is 25- (5 mm × 0.5 mm × k) = 25-2. It becomes 5k (mm2). Therefore, the aperture ratio of the side surface is given by (25-2.5k) / 25 × 100 (%) = 100-10k (%). Eleven cases of k = 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, and 10 were produced.

In Table 1, 11 samples Nos. 1 to 11 were produced as three-dimensional mesh samples. The above-mentioned h = 0, 2 to 20 are 10 mm × 5 mm side surfaces, and correspond to the number of 10 mm connecting threads and the 10 mm aperture ratio (%). Similarly, the above-mentioned k = 0, 1 to 10 corresponds to a 5 mm × 5 mm side surface, a 5 mm number of connecting threads, and a 5 mm aperture ratio (%). Therefore, the 11 types of 10 mm aperture ratio and the 5 mm aperture ratio have the same value, and the average aperture ratio (%) is 100, 90, 80, 70, 60, 50, 40, 30, 20, 10, 0. Become.

In Table 2, a collection test of 0.1 mm cut cotton was carried out using 11 three-dimensional mesh samples having sample numbers 1 to 11. Fill the chalet with cut cotton cut to a length of 0.1 mm, scoop the cut cotton from the opening surface 43 of the three-dimensional mesh sample, and collect it. The volume (mg) of the cut cotton remaining in the internal space 47 of the three-dimensional sample was measured by vibrating the sample lightly up and down. The collected mass was measured for each of the three-dimensional sample without the adsorbent and the three-dimensional sample with the adsorbent. The relationship between the collected mass with and without the adsorbent and the average aperture ratio is illustrated in FIG.
In general, it is considered that the cut cotton is more easily adsorbed and retained due to the adsorption performance of the adsorbent in the case with the adsorbent than in the case without the adsorbent. Further, it is considered that the larger the number of connecting threads 45, the larger the collected mass due to the entanglement effect with the cut cotton. However, as the number of connecting threads 45 increases, the distance between the connecting threads 45 and the connecting threads 45 becomes narrower, the entanglement effect with the cut cotton decreases, and the collected mass is considered to decrease. These total effects need to be determined experimentally.

FIG. 17 shows a collection mass (mg) of cut cotton collected as dust using a large number of three-dimensional mesh samples in which the number of connecting threads 45 arranged on the side surface is changed, and is not hidden by the connecting threads 45. It is a relational figure of the side opening ratio (%) of a region.
The curve indicated by the black square is a graph of the three-dimensional network sample with the adsorbent, and the curve indicated by the black circle is the graph of the three-dimensional network sample without the adsorbent. Both graphs have a peak of 50%, and the graph with the adsorbent is higher than the graph without the adsorbent. In addition, the graph with the adsorbent has a wider base than the graph without the adsorbent. Judging from these results, it can be said that the dust collecting effect is superior when the adsorbent is supported on the three-dimensional network 32.
Further, when it is judged that the collected mass of 10 mg or more is effective, it can be seen that the side aperture ratio of the sample is preferably 20% to 80%. More preferably, the collected mass is 15 mg or more, and the side aperture ratio of the sample is preferably 30% to 70%. The determination of the side aperture ratio in this case ensures that it is good for both with and without the adsorbent.

It can be held and has the effect of being able to suck and clean the held dust with a dust suction device. Furthermore, since it can be mass-produced at low cost, it can be widely used for cleaning purposes in business establishments such as companies, hospitals, schools, and homes.
