And a base element, a fiber element, a connecting element that connects the base part and the fiber element, a cutting element that cuts the fiber element, and a fiber element cut by the cutting element And napping elements to be formed. The predetermined first direction is defined by the direction in which the user moves through the holder during cleaning. In this case, when the cleaning tool has a configuration that rotatably holds the cleaning sheet, the direction in which the cleaning sheet is moved by the user's operation may not be constant. In such a situation, each direction in which the user operates the cleaning sheet can be defined as the first direction. In addition, for example, when the cleaning sheet extends in the longitudinal direction and the intersecting direction that intersects the longitudinal direction, the user intersects the cleaning sheet because it is necessary to perform cleaning work on a wider range of objects to be cleaned. There are cases where the design is performed on the assumption of moving in the direction. In this case, the intersecting direction can define the first direction. In this sense, the predetermined first direction can be defined by a direction designed on the assumption that the user performs a cleaning operation.
Note that the base portion can be preferably constituted by a sheet-like member.

The fiber element is composed of a plurality of fiber bodies extending in the second direction. More specifically, the fiber element can be composed of tow fibers having fiber orientation in the second direction.
The connecting element includes a plurality of connecting portions that extend in the first direction and are formed at predetermined intervals in the second direction. More specifically, when both the base part and the fiber element are made of heat-weldable fibers, the connection element can constitute the connection part by heat-welding both. Moreover, a connection part can also be comprised by adhere | attaching a base part and a fiber element with an adhesive agent.
The cutting element is composed of a plurality of cutting portions formed at predetermined intervals so as to extend in the first direction. In this case, in the cleaning sheet, the region where the cutting element is formed constitutes a cutting element forming region, and the region where the cutting element is not formed constitutes a cutting element non-forming region. In this case, it can be said that the cutting element non-forming region constitutes a non-cutting fiber element.

It can be said that the long-distance raised portion is configured, and further, the raised portion 151 of the central region 101c can be said to constitute the short-distance raised portion in the longitudinal direction.
Further, the cutting portion 141 has a longitudinal long distance in which the length 142y in the longitudinal direction Y of the cutting portion 141 of the end region 101e is longer than the length 144y of the longitudinal direction Y in the cutting portion 141 of the central region 101c. It can be said that the cutting portion is configured, and further, the cutting portion 141 of the central region 101c is configured as a short-distance cutting portion in the longitudinal direction. In addition, it can be said that the length 143y in the longitudinal direction Y of the cutting part 141 of the intermediate region 101m is configured to be shorter than the length 142y and longer than the length 144y.
In addition, the pocket portion 161 has a longitudinal long distance in which the length 162y in the longitudinal direction Y of the pocket portion 161 in the end region 101e is longer than the length 164y in the longitudinal direction Y of the pocket portion 161 in the central region 101c.

When the object to be cleaned is a floor, the dust present on the floor has a relatively long extension such as hair or lint, or a relatively large volume such as cotton dust or bread crumbs. Some have a relatively small volume, such as quartz sand.
In the cleaning operation, since the multi-fiber raised portions 152 first come into contact with the dust, the multi-fiber raised portions 152 capture the dust having the above-described relatively long extension length and the dust having a relatively large volume. Can do. The dust that has not been captured by the majority fiber raised portion 152 is captured by the intermediate number fiber raised portion 153, and the dust that has not been captured by the intermediate number fiber raised portion 153 is captured by the minority fiber raised portion 154. By going through such a cleaning process, the minority fiber raised portions 154 can capture dust having a relatively small volume.

Here, the operation of the pocket portion 161 will be described. Since the long-distance pocket portion 162 first comes into contact with the dust, the long-distance pocket portion 162 can accommodate the dust having the relatively long extension length and the dust having a relatively large volume. The dust that is not captured in the long distance pocket portion 162 is accommodated in the intermediate distance pocket portion 163, and the dust that is not accommodated in the intermediate distance pocket portion 163 is accommodated in the short distance pocket portion 164.

At this time, the fibrous body 121 of the raised portion 151 may enter between the longitudinally uncut fiber portion row region 171y and the object to be cleaned. In this situation, more fibrous bodies 121 enter between the longitudinally uncut fiber part row region 171y and the object to be cleaned in the central region 101c as compared to the end region 101e. Therefore, when the user is performing a cleaning operation, the central region 101c can form a long-distance thickness region 102z3 having a longer distance than the end region 101e in the thickness direction Z. On the other hand, the end region 101e can form a short distance thickness region 102z1 having a shorter distance in the thickness direction Z than the central region 101c. The intermediate region 101m can form a middle distance thickness region 102z2 in the thickness direction Z.
With this configuration, it is possible to facilitate the movement of the dust from the end region 101e to the central region 101c, so that the cleaning surface of the cleaning body 100 can be used more efficiently.

JP 2000-245670 A

  The present invention has been made in view of such a point, and an object thereof is to provide a more rational construction technique relating to a cleaning sheet and a cleaning tool.

In order to solve the above-described problem, according to a preferred embodiment of the cleaning sheet of the present invention, the cleaning sheet is used by being attached to a holder, and a predetermined first direction and a direction intersecting the first direction. And a base element, a fiber element, a connecting element that connects the base part and the fiber element, a cutting element that cuts the fiber element, and a fiber element cut by the cutting element It has a raised element to be formed and a pocket element . The predetermined first direction is defined by the direction in which the user moves through the holder during cleaning. In this case, when the cleaning tool has a configuration that rotatably holds the cleaning sheet, the direction in which the cleaning sheet is moved by the user's operation may not be constant. In such a situation, each direction in which the user operates the cleaning sheet can be defined as the first direction. In addition, for example, when the cleaning sheet extends in the longitudinal direction and the intersecting direction that intersects the longitudinal direction, the user intersects the cleaning sheet because it is necessary to perform cleaning work on a wider range of objects to be cleaned. There are cases where the design is performed on the assumption of moving in the direction. In this case, the intersecting direction can define the first direction. In this sense, the predetermined first direction can be defined by a direction designed on the assumption that the user performs a cleaning operation.
Note that the base portion can be preferably constituted by a sheet-like member.

The fiber element is composed of a plurality of fiber bodies extending in the second direction. More specifically, the fiber element can be composed of tow fibers having fiber orientation in the second direction.
The connecting element includes a plurality of connecting portions that extend in the first direction and are formed at predetermined intervals in the second direction. More specifically, when both the base part and the fiber element are made of heat-weldable fibers, the connection element can constitute the connection part by heat-welding both. Moreover, a connection part can also be comprised by adhere | attaching a base part and a fiber element with an adhesive agent.
The cutting element is composed of a plurality of cutting portions formed at predetermined intervals so as to extend in the first direction. In this case, in the cleaning sheet, the region where the cutting element is formed constitutes a cutting element forming region, and the region where the cutting element is not formed constitutes a cutting element non-forming region. In this case, it can be said that the cutting element non-forming region constitutes a non-cutting fiber element. The non-cutting fiber element is constituted by a plurality of non-cutting fiber parts, and a second direction non-cutting fiber part row region is constituted by a plurality of non-cutting fiber parts extending in the second direction.
A raising element is comprised by the several raising part formed of the fiber body cut | disconnected by the cutting part. A raising part is comprised when the edge part of the cut | disconnected fiber body spaces apart from a connection part. That is, the raised portion has a connection end portion connected to the connection portion and an open end portion, and the open end portion is separated from the base portion. Accordingly, when the user moves the cleaning sheet in a state where the cleaning sheet is in contact with the object to be cleaned, the fibrous body of the raised portion moves so that the open end portion is directed in the direction opposite to the moving direction. Due to the behavior of the raised portions, it becomes possible to efficiently clean the object to be cleaned.
The pocket element is composed of a plurality of pocket portions formed by a space formed between the raised portion and the base portion, and is a first direction pocket formed by continuous adjacent pocket portions in the first direction. The substring area is configured. In addition, it can be said that a pocket element is comprised by the area | region enclosed by a pair of connection part and a pair of 2nd direction non-raising part row | line | column area | region mentioned later. In addition, since dust can be captured with respect to a plurality of pocket portions, cleaning efficiency can be improved.

Therefore, it can be said that the multi-fiber raised portion constitutes the second direction long-distance raised portion as compared with the raised portion in the central region.
  When the object to be cleaned is a floor, the dust present on the floor has a relatively long extension such as hair or lint, or a relatively large volume such as cotton dust or bread crumbs. Some have a relatively small volume, such as quartz sand.
  In the cleaning operation, the raised portion in the end region first comes into contact with the dust. In this case, since the raised portions of the end region constitute a large number of fiber raised portions, the dust having the relatively long extension length and the dust having a relatively large volume can be captured. In this case, dust that has not been captured by the multi-fiber raised portions is captured by the raised portions formed in the central region.

When the object to be cleaned is a floor, the dust present on the floor has a relatively long extension such as hair or lint, or a relatively large volume such as cotton dust or bread crumbs. Some have a relatively small volume, such as quartz sand.
In the cleaning operation, since the multi-fiber raised portions 152 first come into contact with the dust, the multi-fiber raised portions 152 capture the dust having the above-described relatively long extension length and the dust having a relatively large volume. Can do. The dust that has not been captured by the majority fiber raised portion 152 is captured by the intermediate number fiber raised portion 153, and the dust that has not been captured by the intermediate number fiber raised portion 153 is captured by the minority fiber raised portion 154. By going through such a cleaning process, the minority fiber raised portions 154 can capture dust having a relatively small volume.

Here, the operation of the pocket portion 161 will be described. Since the long-distance pocket portion 162 first comes into contact with the dust, the long-distance pocket portion 162 can accommodate the dust having the relatively long extension length and the dust having a relatively large volume. The dust that is not captured in the long distance pocket portion 162 is accommodated in the intermediate distance pocket portion 163, and the dust that is not accommodated in the intermediate distance pocket portion 163 is accommodated in the short distance pocket portion 164.
