[Patent Document 1] Japanese New Patent No. 3145316

[New type of problem to be solved]

According to Patent Document 1, it is possible to easily discern the dust by selecting a flake of a color that is easily noticeable for the dust to be cleaned. However, in general, the dust to be cleaned is not only one color, and dusts of different colors are mixed. Therefore, even if a part of the dust can be recognized, there is a case where it is difficult to recognize other dusts. Therefore, it is desirable to have a cleaning tool that can easily grasp the capture status of dust with different hue. [Means to solve the problem]

One aspect of the cleaning tool is a cleaning tool having a cleaning area abutting the cleaning object, wherein the cleaning area includes a first area where the first fiber body is disposed and a second area where the second fiber body is disposed. A plurality of regions, the first region and the second region are respectively disposed at intervals in a longitudinal direction of the cleaning region and an orthogonal direction orthogonal to the longitudinal direction, the first fibrous body and the second The color difference ΔE of the fiber body was 49.0 or more.

(1) Outline of the embodiment At least the following matters can be made clearer based on the description and drawings in this manual.

One aspect of the cleaning tool is a cleaning tool having a cleaning area contacting a cleaning target. The foregoing cleaning area includes a first area in which the first fibrous body is disposed, and a second area in which the second fibrous body is disposed. A plurality of the first region and the second region are arranged at intervals in a longitudinal direction of the cleaning region and an orthogonal direction orthogonal to the longitudinal direction. The color difference ΔE between the first fibrous body and the second fibrous body is 49.0 or more.

The color of dust is roughly divided into whites such as skin dandruff and dandruff, grays such as dust, human and animal hair, white, black, and brown colors such as sand, and many colors exist. The color difference between the first fibrous body and the color difference ΔE of the second fibrous body is 49.0 or more. Therefore, the hue of the first fibrous body and the second fibrous body are significantly different, and the multi-colored dust can be distinguished. Specifically, one of the first fiber body and the second fiber body has a white tone, and the other has a black tone. Therefore, the fibrous body based on the white tone can exhibit the visibility of black dust, and the fibrous body based on the black can exhibit the visibility of white and gray dust. Since a plurality of first and second areas are arranged at intervals in the cleaning area, a wide range can be used in any one of the longitudinal direction and the orthogonal direction to show the effect of dust with different colors. Recognizability. By using at least one of the first fibrous body and the second fibrous body, the visibility of any one of the dusts having different hue can be exerted, and it becomes easy to grasp the state of dust capture. The color difference ΔE of the claim 1 is ΔE12 of the embodiment.

The cleaning area is a surface that comes into contact with dust, and for example, a sheet-like cleaning tool is provided on the surface of the sheet. In the cleaning area, the first area and the second area may be arranged at a plurality of intervals. For example, at least one of the first fibrous body and the second fibrous body may be continuously arranged on the inner surface of the sheet. A structure in which one of the first area or the second area is intermittently provided on the surface of the sheet, and the structure in which the first fibrous body itself and the second fibrous body itself are intermittently arranged.

Moreover, the first area and the second area may be arranged regularly, or may be arranged irregularly. For example, a belt-shaped or rope-shaped first fiber body or a belt-shaped or rope-shaped second fiber body may be bundled together in a cleaning tool composed of a belt-shaped or rope-shaped fiber body. Each is irregularly configured.

According to an ideal aspect, the first region and the second region are adjacent to each other in the longitudinal direction and the orthogonal direction.

When dust is captured across the first area and the second area, the visibility of the dust can be exhibited by one of the areas.

According to an ideal aspect, the second region is disposed at least one of an end portion in the longitudinal direction of the cleaning region and an end portion in the orthogonal direction of the cleaning region.

Heavier dust, such as sand particles, and larger dust, do not stay on the surface of the cleaning area, and easily enter the interior during the cleaning process. In addition, lighter dust such as dust, dandruff, and dandruff, finer dust, etc. are more likely to stay on the surface of the cleaning area, and stay on the ends of the cleaning area in the longitudinal direction and the ends of the cleaning area in the orthogonal direction. Ministry and so on. The second fibrous body, such as the end portion in the longitudinal direction of the cleaning area and the end portion in the orthogonal direction of the cleaning area, can exert light dust and fine dust against white dandruff, dander, and gray dust. Discrimination of dust and so on. Therefore, it is preferable that the second fiber system has a black tone and the first fiber system has a white tone.

According to an ideal aspect, the first fiber system is the nonwoven fabric sheet. The second fiber system is a fiber bundle having a rising portion capable of rising in a direction separated from the nonwoven fabric sheet.

Dandruff and dandruff are easily attached to a second fibrous body composed of fiber bundles. With the second fibrous body, it is possible to exhibit visibility of dandruff and white dust such as dandruff. Dust is easily pressed on the fiber bundles and nonwoven fabric sheets. Sand particles can become entangled in fiber bundles or adhere to non-woven fabrics. Hair can become entangled in fiber bundles, or adhere to fiber bundles and nonwovens. That is, dust, sand, and hair are easily captured by both the first fibrous body and the second fibrous body having different color differences. With both the first fibrous body and the second fibrous body, the visibility of dust of various colors can be exhibited.

According to an ideal aspect, the fiber bundle covers at least a part of the nonwoven fabric sheet when the rising part is not standing up, and exposes the nonwoven fabric sheet when the rising part is already standing up.

In order to effectively capture dust such as dandruff and dandruff, it is better to raise the standing portion and increase the contact area of the fiber bundle. Since the distinguishability of the first fiber body is different between the state where the rising portion is already standing and the state where it is not standing, based on the distinguishability of the first fiber body, it can be judged whether the cleaning device is suitable for cleaning and can promote fibers. Beam upright operation.

According to an ideal aspect, in a state where the fiber bundle is not upright, the nonwoven fabric sheet has a non-covered portion that is not covered by the fiber bundle.

By providing the non-covered portion, the user can easily find that there are two different shapes (non-woven sheet and fiber bundle) than the structure in which the entire first fiber body is covered with the fiber body constituting the second fiber body. Therefore, the raising operation of the fiber bundle can be promoted.

According to an ideal aspect, the fiber bundle includes: a rising portion capable of rising from the nonwoven fabric sheet; and a non-rising portion arranged along the nonwoven fabric sheet. The standing portions are arranged at intervals in the longitudinal direction and the orthogonal direction. In a state where the rising portion has been raised, a pocket portion surrounded by the non-rising portion and exposing the nonwoven fabric sheet is formed.

Sand particles are captured by being entangled in the uprights or contained in pockets. With the standing portion, the white sand particles can be distinguished, and with the pocket portion, the black sand particles can be distinguished.

According to an ideal aspect, the cleaning tool has a sheet shape having a first surface and a second surface. The cleaning area is provided on the first surface and the second surface, respectively. The basis weight of the second fibrous body on the first surface is greater than the basis weight of the second fibrous body on the second surface.

With such a structure, cleaning can be performed using an appropriate surface depending on the type of main dust. In addition, the larger dust will adhere first, and the smaller dust will float or fall and easily remain. Therefore, it is easier to grasp the capture of dust by using the second surface to capture larger dust and then using the first surface to capture smaller dust such as dandruff and dandruff.

(2) Structure of the cleaning tool Hereinafter, the cleaning tool according to the embodiment will be described with reference to the drawings. In the following drawings, the same or similar parts are assigned the same or similar symbols. However, the drawing is for schematic display, please note that the ratio of each size will be different from the real thing. Therefore, specific dimensions and the like should be judged with reference to the following description. In addition, the respective drawings may include portions having different dimensional relationships, ratios, and the like.

The cleaning tool of the embodiment is used after being attached to a holder. However, as another embodiment, it may be a cleaning tool which is used without being attached to a holder. Examples of the cleaning tool that is used without being attached to the holder include, for example, a cleaning cloth for wiping a cleaning surface such as the floor. The cleaning area of the cleaning tool used without being mounted on the holder is an area that can be in contact with dust. For example, the entire cleaning tool constitutes a cleaning area.

FIG. 1 is a perspective view showing a holder in which a cleaning device is installed. Fig. 2 is a plan view showing an outline of the cleaning tool. The holder 200 includes a holding portion 210 for a user to hold, a tube portion 250 extending from the holding portion 210, a head portion 220, and a connecting portion 260 that connects the tube portion 250 and the head portion 220.

As shown in FIG. 1, the head 220 has a first head surface 220Z1 facing the user when the user cleans the ground. The head 220 also has a second head surface 220Z2 that is a surface facing the first head surface 220Z1. The second head surface 220Z2 is the surface facing the ground when the user cleans the ground. The first head surface 220Z1 includes a holding portion 230 for holding the cleaning tool 100. The holding unit 230 holds the cleaning tool 100 detachably. As shown in FIG. 1, the second head surface 220Z2 is formed with a contact portion 240 for contacting the cleaning tool 100 mounted on the holding portion 230.

Fig. 2 is a plan view showing an outline of the cleaning tool. The cleaning tool 100 is a thin sheet, extending in the longitudinal direction Y, a direction orthogonal to the longitudinal direction Y, that is, an orthogonal direction X, and a direction crossing the longitudinal direction Y and the orthogonal direction X, that is, a thickness direction Z. The longitudinal direction and the orthogonal direction refer to an arbitrary direction of the cleaning tool as a longitudinal direction, and a direction orthogonal to the longitudinal direction is referred to as an orthogonal direction. For example, a cleaning tool having a cylindrical shape and an outer peripheral surface constituting a cleaning area may be used with a cylindrical axial direction as a longitudinal direction and an outer peripheral surface circumferential direction as an orthogonal direction.

The cleaning tool 100 is designed for a user to reciprocate the cleaning tool 100 in the orthogonal direction X. The cleaning tool 100 includes an end portion 100X in the orthogonal direction X and an end portion 100Y in the longitudinal direction Y.

FIG. 3 is an exploded view showing the structure of the cleaning tool 100. As shown in FIG. 3, the cleaning tool 100 has a first surface 100Z1, and a surface opposite to the first surface 100Z1, that is, a second surface 100Z2. The cleaning tool 100 includes a base portion 110, a cover portion 120, and a side portion 180. The cover portion 120 and the side portion 180 are provided on the first surface 100Z1 side and the second surface 100Z2 side, respectively. The side portion 180 is a region including an end portion in the orthogonal direction X of the lid portion 120 and the base portion 110, and is joined to the lid portion 120 and the base portion 110. That is, the ends in the orthogonal direction X of the base portion 110 and the cover portion 120 are held by the side portion 180 on the first surface 100Z1 side and the side portion 180 on the second surface 100Z2 side, respectively. The base portion 110 and the side portion 180 may be joined by thermally melting a predetermined region.

When the cleaning tool 100 is mounted on the head 220 of the holder 200, the area having the side portion 180 may be folded back toward the first head surface 220Z1 side. The [returned area] of the cleaning tool 100 is an area that is not in contact with the abutting portion 240 of the head 220. A part of the side portion 180 folded back toward the first head surface 220Z1 is fixed to the holding portion 230 of the holder 200. When mounted on the head 220 of the holder 200, the [unreturned area] of the cleaning tool 100 constitutes a cleaning area 101 that abuts the cleaning target. The length in the orthogonal direction of the contact portion 240 of the holder is shorter than the interval in the orthogonal direction of the pair of side portions 180. Since the center of the orthogonal direction of the abutting portion is aligned with the center of the cleaning tool in the orthogonal direction, the side portion 180 is folded back toward the first head surface 220Z1 and is not disposed on the second head surface 220Z2 side.

The cleaning area 101 may be provided on each of the first surface 100Z1 and the second surface 100Z2. The state in which the abutting portion 240 of the holder faces the first surface 100Z1 side, the cleaning area 101 is provided in the second surface 100Z2, and the state in which the abutting portion 240 of the holder faces the second surface 100Z2 side. A cleaning area 101 is provided on the first surface 100Z1. That is, by exchanging the first surface 100Z1 and the second surface 100Z2 of the cleaning tool, the cleaning area 101 can be formed on both surfaces.

The cleaning area 101 is constituted by a fibrous body. The fibrous body includes at least a first fibrous body 10 and a second fibrous body 20. The color difference ΔE12 between the first fiber body 10 and the second fiber body 20 is 49.0 or more. The color difference ΔE12 between the first fiber body and the second fiber body is 49.0 or more. Therefore, the hue of the first fiber body and the second fiber body are significantly different, and the multi-color dust can be distinguished. The color difference ΔE12 between the first fiber body 10 and the second fiber body 20 is preferably 67.0 or more, and more preferably 77.0 or more. The method of measuring the color difference will be described in detail later.

The color combination of the first fibrous body and the second fibrous body is not particularly limited. For example, one of the first fibrous bodies has a white tone and the other has a black tone. Therefore, the fibrous body based on the white tone can exhibit the visibility of black dust, and the fibrous body based on the black can exhibit the visibility of white and gray dust. The white-based fiber system refers to a fiber body in which the ΔL of the (L * a * b *) color space of the white reference plate is 4.0 or less. The black-based fiber system refers to a fiber body in which the ΔL of the color space of the white reference plate is 54.0 or more. As a combination of other colors, one of the first fibrous body may be a white tone and the other may be a red tone. This ΔL is a lab value at the time of measurement using calculation formulas 1 and 2 described later, and specifically, can be calculated from (L0-L1) and (L0-L2).

The color difference ΔE1 of the first fibrous body 10 to the white reference plate may be 11.0 or less, preferably 6.0 or less, and more preferably 1.0 or less. The color difference ΔE2 of the second fiber body 20 to the white reference plate may be 54.0 or more, and is preferably 80.0 or more.

The first fiber body 10 constitutes the base portion 110, and the second fiber body 20 constitutes the cover portion 120 on the first surface side and the cover portion 120 on the second surface side. As shown in FIG. 2 and the like, the base portion 110 and the cover portion 120 are connected by a connecting element 130 extending in the orthogonal direction X. The connection element 130 is constituted by a plurality of connection portions 131 arranged in the longitudinal direction Y at intervals. The connecting element 130 can also be formed by thermally melting a predetermined region of the base portion 110 and the cover portion 120. The connection portion 131 includes a region having a predetermined inclination angle with respect to a center line 100YC (see FIG. 2) extending in the longitudinal direction Y of the cleaning tool 100. Furthermore, in the present embodiment, "the constituent elements and the like extend in the orthogonal direction X (length direction Y)" indicates the case where the constituent elements and the like are parallel to the orthogonal direction X (length direction Y), and the extension of the constituent elements and the like The case where the direction has an orthogonal X component.

FIG. 4 is an enlarged view of part A shown in FIG. 2. Fig. 5 is an explanatory view showing a structure of a part B of Fig. 4 in a state where the rising portion is not raised. Fig. 6 is an explanatory view showing a structure of a part B of Fig. 4 in a state where the rising portion has been raised. Fig. 7 is a sectional view of the cleaning tool taken along the line C-C in Fig. 6. The base portion 110 is formed of a nonwoven fabric sheet 111 as the first fiber body 10. The cover portion 120 is formed by a fiber bundle 121 as the second fiber body 20. The fiber bundle 121 is capable of standing up in a direction separated from the nonwoven fabric sheet 111. The fiber bundle 121 is a fiber assembly having fiber orientation in the longitudinal direction Y. The fiber bundle 121 uses thermoplastic fibers. The fiber bundle 121 is typically obtained by opening the fiber bundle fibers. The fiber bundle 121 includes a raised portion 122 that can stand from the nonwoven sheet 111 and a non-raised portion 123 (see FIG. 6) arranged along the nonwoven sheet 111. The rising portion 122 includes a first fiber bundle and a second fiber bundle described later, and the non-rising portion 123 includes a portion connected by a connecting portion 131 and a non-cutting portion 125 described later.

As shown in FIG. 4 and the like, a cutting element 140 extending in the orthogonal direction X is formed between the pair of connection portions 131. The cutting element 140 is configured by continuously arranging a plurality of cutting portions 141 so as to extend in the orthogonal direction X at predetermined intervals. The cutting portion 141 is located between the pair of connecting portions 131 in the longitudinal direction Y.

As shown in FIG. 5, the fiber bundle 121 is arranged in a state where the fiber bundle 121 is not erected and covers at least a part of the surface of the base 110. Between the pair of connecting portions 131, there may be: a cutting area 145 in which the nonwoven fabric sheet 111 and the fiber bundle 121 are cut by the cutting portion 141; and a cutting area 145 located in the orthogonal direction X. The non-cutting region 146 cut by the cutting section 141. A fiber bundle 121 is disposed in the non-cutting region 146 to connect a pair of connection portions 131. The fiber bundle 121 connecting the connection portions 131 constitutes a non-cutting portion 125. The non-cutting portion 125 may not be connected to the base portion 110 in an area other than the connection portion 131 (the area between the pair of connection portions 131 in the longitudinal direction Y), and may float to the base portion 110 (see FIG. 7). Both ends of the non-cutting portion 125 in the longitudinal direction Y are connected to the base portion 110 through a connection portion 131. Therefore, the non-cutting portion 125 constitutes the non-rising portion 123.

As shown in FIGS. 5 and 6, the fiber bundle 121 of the cutting region 145 includes a first fiber bundle 121A connected to the first connection portion 131A of one of the pair of connection portions 131, and a second connection portion. The second fiber bundle 121B of 131B. At least one of the first fiber bundle 121A and the second fiber bundle 121B is configured to be able to stand using the connection portion 131 as a base point. In the cleaning tool 100 according to the embodiment, both the first fiber bundle 121A and the second fiber bundle 121B are configured to be able to stand. Therefore, both the first fiber bundle 121A and the second fiber bundle 121B constitute a rising portion 122. In addition, the second fiber bundle 121B is fixed to the cutting portion 141 and is fixed to the non-woven sheet 111 by pressing, and the first fiber bundle is fixed to the cutting portion 141 and is not fixed to the non-woven sheet 111. Therefore, the first fiber bundle 121A is configured to stand more easily than the second fiber bundle 121B. FIG. 6 shows a state where the first fiber bundle 121A stands up and the second fiber bundle 121B does not stand. In addition, the second fiber bundle 121B is press-bonded and fixed to the nonwoven fabric sheet 111, and is configured not to stand on the nonwoven fabric sheet 111. In such a configuration, the second fiber bundle 121B constitutes the non-rising portion 123.

The cutting portion 141 is offset from the longitudinal direction Y by a center line in the longitudinal direction Y of the pair of connecting portions 131. That is, the length in the longitudinal direction Y of the first fiber bundle 121A is longer than the length in the longitudinal direction Y of the second fiber bundle 121B. The length in the longitudinal direction Y of the first fiber bundle 121A may be the same as the length in the longitudinal direction Y of the second fiber bundle 121B.

In addition, since the first fiber bundle 121A is attached to the cutting portion 141 and is not press-fitted and fixed with the nonwoven fabric sheet 111, the fiber bundle 121 floats slightly from the nonwoven fabric sheet 111 in a non-standing state, rather than forming the cutting portion 141. Previously, the length in the length direction Y became shorter. Therefore, as shown in FIG. 5, in a state where the fiber bundle 121 is not standing, a gap is formed between the cutting portion 141 and the first fiber bundle 121A, and the nonwoven fabric sheet 111 is partially exposed. Here, the gap between the cutting portion 141 and the first fiber bundle constitutes the non-covered portion 126 of the present creation. The non-covered portion 126 is surrounded by a pair of non-cutting portions 125, the tip of the first fiber bundle 121A, and the tip of the second fiber bundle 121B.

By letting a hand or the like slide along the surface of such a cleaning area 101, the fiber bundle 121 is formed to stand on the nonwoven fabric sheet 111. In a state where the standing portion 122 is already standing, at least the first fiber bundle 121A is standing with the connection portion 131 as a base point, and the nonwoven fabric sheet 111 is exposed. As shown in FIG. 6, in the state where the rising portion 122 has been raised, the cleaning area 101 is formed with a pocket element 150 surrounded by the non-rising portion 123. The pocket element 150 is constituted by a plurality of pocket portions 151. The pocket portion 151 is surrounded by a pair of non-cutting portions 125 and a pair of connecting portions 131. The length in the longitudinal direction Y of the pocket portion 151 is the interval between the pair of connecting portions 131, and the length in the orthogonal direction X of the pocket portion 151 is the interval between the pair of non-cutting portions 125.

In the cleaning area 101 of the cleaning tool thus constituted, a first area R1 in which the base portion 110 (non-woven sheet 111) is exposed is provided in a plan view, and a cover portion 120 (fiber bundle 121) is disposed on the base portion 110 in a first view. 2 area R2. The first region R1 and the second region R2 are arranged at intervals in the longitudinal direction Y and the orthogonal direction X of the cleaning region 101, respectively. The cleaning area 101 is constituted by a surface mounted on a holder. Therefore, the second region R2 is formed as a region where the second fibrous body 20 is arranged for the present creation, and the first region R1 where the base 110 is exposed is formed as a region where the first fiber body 10 is arranged as the present creation.

The state in which the rising portion 122 of the fiber bundle 121 has been erected and the state in which the rising portion 122 of the fiber bundle 121 has not erected, the first region R1 and the second region R2 are respectively in the longitudinal direction Y and the orthogonal direction X of the cleaning region 101, Place at intervals. Specifically, in a state where the fiber bundle 121 is already standing, in the cleaning area 101, a pocket portion 151 is arranged at intervals in the longitudinal direction Y and the orthogonal direction. The pocket portion 151 is formed as the first region without covering the nonwoven fabric sheet 111 with the fiber bundle 121. In a state where the fiber bundle 122 has been raised and a state where the rising portion 122 has not been raised, a non-cutting portion 125 and a connection portion 131 are arranged in the cleaning area 101 at intervals in the orthogonal direction. The non-cutting portion 125 is formed as the second region R2 by covering the nonwoven fabric sheet 111 with the fiber bundle 121. The connection portion 131 is formed as the second region R2 by covering the nonwoven fabric sheet 111 with the fiber bundle 121. In a state where the rising portion 122 is not raised, a non-covered portion 126 is formed in the cleaning area 101. The non-covered portion 126 is formed as the first region R1 without covering the nonwoven fabric sheet 111 with the fiber bundle 121. Furthermore, since the cleaning tool is used in a state where the fiber bundle 121 is already standing, the first region R1 and the second region R2 are at least in the state where the fiber bundle 121 is already standing, respectively, in the longitudinal direction Y and the positive direction of the cleaning region 101. A plurality of intersecting directions may be arranged at intervals.

Next, a description will be given of the dust-collecting aspect of the thus constructed cleaning tool. The fiber bundle 121 is configured to be able to stand up from the nonwoven fabric sheet 111, and by being brought into contact with the cleaning surface, fine particles, hair such as slim dust, and dust are entangled and captured. In addition, the fiber bundle 121 is brought into contact with the cleaning surface, and large dust like sand particles are scraped off. Sand-like dust enters the pocket portion 151 from the fiber bundle 121 and is held without falling. In addition, since the connecting portion 131 is inclined and arranged side by side with respect to the orthogonal direction X as the cleaning direction, when the cleaning tool 100 advances in the orthogonal direction X, the cleaning object is captured by the connecting portion 131 extending in a cross shape. , And is induced and entangled toward the fiber bundle 121 adjacent to the joint portion, thereby maintaining it.

The first fiber body 10 is different from the second fiber system in color difference, and at least one of them easily exhibits visibility of dust having different color tones. The color difference ΔE12 between the first fiber body 10 and the second fiber body 20 is 49.0 or more. Since the first region R1 and the second region R2 are respectively arranged at intervals, a wide range can be exhibited in any one of the length direction Y and the orthogonal direction X, and dust of different colors can be exhibited. Recognizability. Therefore, by using at least one of the first fibrous body 10 and the second fibrous body 20, the visibility of any one of the dusts having different hue can be exerted, and it becomes easy to grasp the state of dust capture.

The color of dust is roughly divided into whites such as dandruff and dandruff, grays such as dust, human and animal hair, white, black, and brown colors such as sand, and many colors exist. Depending on the type of dust, the capture state of the cleaning tool will be different. Specifically, dandruff and dandruff are white. One of the first fibrous body 10 and the second fibrous body 20 has a black tone, and is easily distinguishable from white dust. In addition, dandruff and dandruff are easily captured by the fiber bundle 121. Therefore, the second fiber body 20 constituting the fiber bundle is preferably black-based. Dust is easily pressed against the fiber bundle 121 and the nonwoven fabric sheet 111. Sand particles are entangled in the fiber bundle 121 or attached to the nonwoven fabric sheet 111. Human and animal hairs are arranged throughout the fiber bundle 121 and the non-woven sheet 111. That is, dust, sand, and hair are easily captured by the first fibrous body 10 and the second fibrous body 20 having different color differences.双方 Both the first fibrous body 10 and the second fibrous body can exhibit the visibility of dust of various colors. By grasping the condition of dust capture, it is possible to obtain the effect of improving the satisfaction during cleaning and the effect of continuous use in an unsanitary state.

The first region R1 and the second region R2 may be adjacent to each other in the longitudinal direction Y and the orthogonal direction X. Since the dust is distributed throughout the first fibrous body 10 and the second fibrous body, the visibility of the dust can be exhibited in any one of the regions. In particular, it is possible to improve the recognizability of long-shaped dust hairs.

The interval in the orthogonal direction of the first region R1 and the interval in the orthogonal direction of the second region R2 in a state where the rising portion is already raised may be 25 mm or less, more preferably 10 mm or less, and even more preferably 5 mm or less. According to such a structure, the 1st fiber body 10 and the 2nd fiber body can be arrange | positioned in balance, and it becomes easier to exhibit the effect of the dust recognition by both the 1st fiber body 10 and the 2nd fiber body. The interval in the orthogonal direction of the first region R1 in a state where the rising portion has stood up is the length of the orthogonal direction of the second region R2 and the length of the orthogonal direction of the non-cutting portion 125. The interval in the orthogonal direction of the second region R2 in a state where the rising portion has stood up is the length in the orthogonal direction of the first region R1 and the length in the orthogonal direction of the pocket portion 151.

The interval in the longitudinal direction Y of the first region R1 and the interval in the longitudinal direction Y of the second region R2 in a state where the rising portion is already raised may be 25 mm or less, and more preferably 20 mm or less. According to such a structure, the first fibrous body 10 and the second fibrous body 20 can be arranged in a balanced manner, and the effect of identifying the dust by both the first fibrous body 10 and the second fibrous body 20 becomes easier. The interval in the longitudinal direction Y of the first region R1 in the state where the rising portion has stood up is the length of the longitudinal direction Y of the second region R2 and the length of the longitudinal direction Y of the connection portion 131. The interval in the longitudinal direction Y of the second region R2 in the state where the rising portion has been erected is the length in the longitudinal direction Y of the first region R1, and is the interval in the longitudinal direction Y of the pocket portion 151 and the longitudinal direction of the connection portion 131. Furthermore, the interval in the orthogonal direction of the first region R1, the interval in the orthogonal direction of the second region R2, the interval in the longitudinal direction of the first region R1, and the interval in the longitudinal direction of the second region R2 may be constant. Can be partially different.

The second region R2 is arranged on at least one of an end portion in the longitudinal direction of the cleaning region 101 and an end portion in the orthogonal direction of the cleaning region 101. In the embodiment, the second fiber body is arranged at both ends in the longitudinal direction of the cleaning area 101. Heavier dust, such as sand particles, and larger dust, do not stay on the surface of the cleaning area 101, and easily enter the interior during the cleaning process. In addition, lighter dust such as dust, dandruff, and skin patches, finer dust, etc. are more likely to stay on the surface of the cleaning area 101, and easily stay at the ends of the cleaning area 101 in the longitudinal direction, and orthogonal to the cleaning area 101. The end of the direction and so on. The second fibrous body such as an end portion in the longitudinal direction of the cleaning region 101 and an end portion in the orthogonal direction of the cleaning region 101 can exhibit visibility of light dust, fine dust, and the like.

The fiber bundle 121 covers at least a part of the nonwoven fabric sheet 111 in a state where the fiber bundle 121 is not upright, and exposes the nonwoven fabric 111 in a state where the fiber bundle 121 is already upright. In order to effectively capture dust such as dandruff and dandruff, it is preferable to raise the rising portion 121 to increase the contact area of the fiber bundle 121. Since the visibility of the first fiber body 10 is different between the state where the rising portion 121 has been erected and the state where it is not erected, it can be judged whether it is a cleaning tool in a state suitable for cleaning based on the distinguishability of the first fiber body 10. The raising operation of the fiber bundle 121 can be promoted.

In a state where the fiber bundle 121 is not standing, the nonwoven fabric sheet 111 has a non-covered portion that is not covered by the fiber bundle 121. The non-covered portion 126 is an area surrounded by the pair of non-cutting portions 125, the first fiber bundle 121A, and the second fiber bundle 121B in a state where the fiber bundle 121 is not standing. By providing the non-covered portion 126, the user can easily find that there are two different shapes (the non-woven sheet 111 and the fiber bundle 121) than the structure in which the entire first fiber body 10 is covered by the second fiber body 20. Therefore, the raising operation of the fiber bundle 121 can be promoted.

In the cleaning area 101, a pocket portion 151 is formed in a state where the raised portion is already raised, surrounded by a non-rised portion, and the non-woven sheet 111 is exposed. Sand particles are captured by being entangled in the standing portion or contained in the pocket portion 151. With the standing portion, the white sand particles can be distinguished, and with the pocket portion 151, the black sand particles can be recognized. The pocket portion 151 is surrounded by a pair of non-cutting portions 125 and a pair of connecting portions 131, and the nonwoven fabric sheet 111 is exposed. Therefore, the non-woven sheet 111 serving as the bottom of the pocket portion 151 is not homogeneous to the surrounding fiber bundle 121, but the color difference ΔE12 to the surrounding fiber bundle 121 is at least 49.0 or more. Therefore, it is easy to show the recognizability of dust of various sizes and colors such as captured particles, hair, dust, and sand.

Next, a method for measuring the color difference of this embodiment will be described. The color difference ΔE1 of the first fibrous body 10 to the white reference plate and the color difference ΔE2 of the second fibrous body to the white reference plate can be used to measure the lab value of the white reference plate and the target sample (the first fiber body or the second fiber body). Calculated by the lab value. As a reference color when measuring color difference, a white reference plate (L96.76 a + 0.44 b + 2.17) was used. As the color difference measuring device, for example, CR-300 manufactured by Konica Minolta can be used. As a light source of the measuring device, a C light source (a specification of the International Commission on Illumination (CIE)) can be used. The diameter of the measuring window of the measuring machine is 40 mm. Here, L is the value of the brightness index, and a and b are the plane coordinates of chromaticity. The numerical value of the white reference plate and the numerical value of the target sample measured on the white reference plate were calculated by inserting them into calculation formulas 1 and 2.

When the Lab value of the white reference plate is L0, a0, and b0, and the Lab value of the first fiber body of the target sample is L1, a1, b1, and the Lab value of the second fiber body is L2, a2, b2, ΔE1 can be obtained by calculation formula 1 and ΔE2 can be obtained by calculation formula 2.

[Calculation formula 1]

[Calculation formula 2] It can be calculated by the aforementioned calculation formula.

The color difference ΔE12 between the first fiber body 10 and the second fiber body 20 is set when the Lab value of the first fiber body 10 is set to L1, a1, b1, and the Lab value of the second fiber body is set to L2, a2, or b2. Calculate ΔE12 by calculation formula 3.

[Calculation formula 3] Next, a cleaning tool according to a modification will be described with reference to FIGS. 8 and 9. In the following description, the same configurations as those of the above-mentioned embodiment are denoted by the same reference numerals, and descriptions thereof will be omitted. A cleaning tool 100A according to a modification example includes a plurality of first fiber bodies 11 and a plurality of second fiber bodies 21 arranged between the first fiber bodies 11. The first fiber body 11 is arranged on the first surface and the second surface of the cleaning tool. On the first surface, an opening through which a holder is inserted is formed. The second surface constitutes the cleaning area 101A. The first fiber system is composed of a nonwoven fabric sheet, and has a cutting portion 143 extending in the orthogonal direction X. The second fibrous body 21 is constituted by a fluffy fibrous body. Both the first fibrous body 11 and the second fibrous body 21 are made of flexible fibers, and are easily deformed when used.

The second fibrous body 21 located inside the thickness direction Z of the first fibrous body 11 is in a state where the first fibrous body 11 is not deformed at the cutting portion 143 and cannot be recognized from the outer side. The state in which the portion 143 has been deformed can be identified through a gap formed by the cutting portion 143. The first fiber body 11 and the second fiber body 21 may be separated from each other in the longitudinal direction Y and the orthogonal direction X of the cleaning area 101A in a state where at least one of the first fiber body 11 and the second fiber body 21 is deformed. A plurality are arranged at intervals.

Moreover, in the cleaning tool of another modification, the cover part 120 of a 1st surface side, and the cover part 120 of a 2nd surface side may have the same structure, and may have a different structure. For example, the cover portion and the base portion on the first surface side may be configured by a second fiber body, and the cover portion on the second surface side may be configured by a first fiber body. Since the cover portion and the base portion on the first surface side are the second fibrous body, the second region is provided in almost the entire range of the first surface. For example, in the case where the second fiber body has a black tone, the entire first surface becomes almost black. In addition, since the cover portion on the first surface side is the first fibrous body and the base portion is the second fibrous body, the first area and the second area are mixed in the second surface. For example, in a case where the first fiber body has a white tone and the second fiber body has a black tone, the first surface becomes black and white. As described above, since the ratio of the first fibrous body to the second fibrous body is different between the first surface and the second surface, cleaning can be performed using an appropriate surface depending on the type of the main dust. In such a structure, the basis weight of the second fibrous body on the first surface is larger than that of the second fibrous body on the second surface. The larger dust will attach first, and the smaller dust will float or fall and easily remain. Therefore, after cleaning using the second surface, and then performing final cleaning using the first surface, it is easier to grasp the state of dust capture.

Next, the discriminative evaluation of the dust of the cleaning tool comprised in this way is demonstrated. The discriminative evaluation of dust was based on the fibrous bodies of samples 1 to 8. Table 1 shows the difference (ΔL, Δa, and Δb) of the Lab values of each sample with respect to the white reference plate, the color difference ΔE with respect to the white reference plate, and the hue. Δa is obtained by a0-a1, and Δb is obtained by b0-b1.

The discriminative evaluation test is to select the first fibrous body sample and the second fibrous body sample from the fibrous bodies of samples 1 to 10, and use black dust (black hair, sand particles) and white dust (dander, Dandruff) were adhered to both samples, and the visibility of the black dust and the visibility of the white dust were evaluated visually. There are 10 evaluators. The evaluation is "◎◎" when the rate of recognizable dust is 90% or more. The evaluation is "◎" when the rate of recognizable dust is 80% or more. When the dust evaluator is 70% or more, the evaluation is "0", when the dust evaluable is 50% or more, the evaluation is "Δ", and when the dust evaluable is less than 50%, The situation was evaluated as "×". The evaluation results are shown in Table 2.

As shown in Table 2, from Examples 1 to 5, good results were obtained in the visibility of black dust and the visibility of white dust. Based on this result, the color difference ΔE12 between the first fibrous body and the second fibrous body is preferably 49.0 or more. Comparative Examples 1, 2 and 4, and Examples 1 to 5 obtained good results with respect to the visibility of black dust. Based on this result, the ΔL of the first fiber body is preferably 3.61 or less, and the ΔE1 of the first fiber body is preferably 5.17 or less. In Comparative Example 5, Examples 1 to 5, good results were obtained with respect to the visibility of white dust. Based on this result, the ΔL of the second fiber body is preferably 54.49 or more, and the ΔE2 of the second fiber body is preferably 54.51 or more.

As mentioned above, the present invention has been described in detail using the above-mentioned embodiment. However, for those skilled in the art, the present invention is not limited to those described in this specification. The present invention can be implemented with various amendments and changes within the technical ideas and scope of the present invention as defined by the description in the scope of the patent application. Therefore, the purpose of the description in this manual is for illustration, and is not intended to limit the creation. [Industrial availability]
