A cleaning cloth provided with a cleaning part constituted by a pile on at least one surface of a sheet-like base part,
The cleaning part has a water absorbent fiber pile part made of a water absorbent yarn pile, and a non water absorbent fiber pile part made of a non water absorbent thread pile and constituting a part other than the water absorbent fiber pile part in the cleaning part. And
Both the water absorbent fiber pile portion and the non-water absorbent fiber pile portion are provided over the entire cleaning portion.

  When water is included in the cleaning part, the water absorbent fiber pile part provided over the entire cleaning part mainly contains moisture, and constitutes a part other than the water absorbent fiber pile part in the cleaning part and is provided over the entire cleaning part. The non-water-absorbing fiber pile part does not contain much water. When the cleaning surface such as the floor surface is wiped by the cleaning unit, the frictional resistance acting between the cleaning unit and the surface to be cleaned is large in the water-absorbing fiber pile portion having a large ratio of moisture, and does not contain much moisture. Small in the fiber pile.

  Since the frictional resistance acting between the cleaning portion and the surface to be cleaned when wiping the surface to be cleaned such as the floor surface by the cleaning portion is reduced in the non-water absorbent fiber pile portion provided over the entire cleaning portion, This is suitable for cleaning work. The water absorption fiber pile portion that is provided throughout the cleaning portion mainly takes charge of wiping off the dirt on the surface to be cleaned and supplying moisture for separating the dirt stuck to the surface to be cleaned from the surface to be cleaned. . Moreover, the non-water-absorbing fiber pile part which does not contain much moisture provided over the whole cleaning part acts suitably about isolate | separating the dirt which stuck from the to-be-cleaned surface in the state to which the water | moisture was supplied. Therefore, the water-absorbing fiber pile portion and the non-water-absorbing fiber pile portion combine to exhibit an excellent cleaning effect.

  In the cleaning cloth, the ratio of the area occupied by the water absorbent fiber pile portion and the non-water absorbent fiber pile portion in the cleaning portion is preferably 3: 7 to 8: 2.

  In this case, when the ratio of the area occupied by the water-absorbing fiber pile portion and the non-water-absorbing fiber pile portion in the cleaning portion is 3: 7 to 8: 2, the frictional resistance reducing action and the sticky dirt separating action by the non-water-absorbing fiber pile part and It is preferable for wiping off dirt by the water-absorbing fiber pile portion and effectively exerting water supply action.

  In the cleaning cloth, it is preferable that the cleaning portion is composed of a plurality of strip-shaped water-absorbing fiber pile portions and a plurality of strip-shaped non-water-absorbing fiber pile portions alternately adjacent in parallel.

  In this case, since the cleaning portion is composed of a plurality of strip-shaped water absorbent fiber pile portions and a plurality of strip-shaped non-water absorbent fiber pile portions that are alternately adjacent to each other in parallel, the frictional resistance reducing action and sticky dirt separation by the non-water absorbent fiber pile portion The action and the dirt wiping and water supply action by the water absorbent fiber pile part, especially when the adjacent direction of the belt-like water absorbent fiber pile part and the belt-like non-water absorbent fiber pile part is the main wiping direction of the cleaning part. Can be effectively demonstrated over a wide range.

  In the cleaning cloth, it is preferable that the water absorbent yarn pile constituting the water absorbent fiber pile portion and the non-water absorbent yarn pile constituting the non water absorbent fiber pile portion are both loop piles.

  In this case, the water-absorbent yarn pile that constitutes the water-absorbing fiber pile portion and the non-water-absorbent yarn pile that constitutes the non-water-absorbent fiber pile portion are both loop piles. Excellent separation effect.

  In the cleaning cloth, the height of the pile relative to the sheet-like base is higher in the non-water absorbent fiber pile portion than in the water absorbent fiber pile portion, and the water absorbent fiber pile portion and the non-absorbent fiber pile portion are pressed by the pressing of the cleaning portion against the surface to be cleaned during cleaning. It is preferable that any of the water absorbent fiber pile portions can come into contact with the surface to be cleaned.

  In this case, the height of the sheet-like base portion is so high that the water-absorbing fiber pile portion and the non-water-absorbing fiber pile portion can be in contact with the surface to be cleaned by pressing the cleaning portion against the surface to be cleaned during cleaning. The non-water-absorbing fiber pile part is higher than that. For this reason, the water-absorbing fiber pile portion can sufficiently supply moisture for wiping off dirt on the surface to be cleaned and separating dirt stuck to the surface to be cleaned from the surface to be cleaned. It is possible to more effectively realize the reduction in the frictional resistance between the non-water-absorbing fiber pile portion and the separation of the dirt stuck to the surface to be cleaned by the non-water-absorbing fiber pile portion.

  According to the cleaning cloth of the present invention, when the surface to be cleaned such as the floor surface is wiped by the cleaning unit, the friction resistance acting between the cleaning unit and the surface to be cleaned is provided over the entire cleaning unit. Since it is reduced in the fiber pile portion, it is suitable for cleaning work, and the supply of moisture for wiping off the dirt on the surface to be cleaned and separating the dirt stuck to the surface to be cleaned from the surface to be cleaned is The water-absorbing fiber pile part that is provided over the entire cleaning part is mainly responsible for separating dirt stuck from the surface to be cleaned in a state where moisture is supplied. Since the non-water-absorbing fiber pile portion that does not contain much moisture works favorably, the water-absorbing fiber pile portion and the non-water-absorbing fiber pile portion combine to exhibit an excellent cleaning effect.

  Embodiments of the present invention will be described with reference to the drawings.

  1 and 2 both relate to a cleaning cloth as an example of an embodiment of the present invention. FIG. 1 is a schematic bottom view and FIG. 2 is a schematic cross-sectional view.

  This cleaning cloth A is for cleaning with water in a state where it is held by a cleaning cloth holding head with a handle, and is constituted by a pile on the front side surface of the rectangular sheet-like base S. The cleaning part C is provided. The cleaning part C is a rectangular part extending over the entire length in the longitudinal direction except for the lateral direction side part S1 on both sides of the sheet-like base S. When the cleaning cloth A is held on the cleaning cloth holding head, the short side portion S1 is such that the cleaning section C is positioned below the sheet-like base S on the lower side of the cleaning cloth holding head. This is a part for holding by a holding part such as a clip part on the upper side of the holding head.

  The sheet-like base S is, for example, a base fabric, but is not limited thereto. Materials other than cloth, such as a mesh material, can also be used.

  The cleaning part C is composed of a plurality of strip-shaped water-absorbing fiber pile portions Y and a plurality of strip-shaped non-water-absorbing fiber pile portions U that are alternately adjacent to each other in the short direction. The water-absorbing fiber pile portion Y is made of a water-absorbing yarn loop pile, and the non-water-absorbing fiber pile portion U is made of a non-water-absorbing yarn loop pile. The width of the non-water absorbent fiber pile portion U is configured to be slightly narrower than the width of the water absorbent fiber pile portion Y. In this example, there are six water-absorbing fiber pile portions Y and five non-water-absorbing fiber pile portions U. Thus, a plurality of strip-shaped water-absorbing fiber pile portions Y adjacent in parallel and a plurality of strip-shaped non-water-absorbing portions. In the case of the cleaning part C composed of the fiber pile part U, it is desirable to provide at least two non-water absorbent fiber pile parts U.

  An ultrafine synthetic fiber yarn can be used as the water-absorbing yarn. The ultrafine synthetic fiber is produced, for example, by separating the sea component of the sea-island type composite fiber with a solvent or a decomposing agent, or by separating using a separation type split fiber composed of two or more components. It can be produced by a known production method. As the non-water-absorbing yarn, a non-water-absorbing synthetic fiber yarn can be used.

  The pile height from the front side surface of the sheet-like base S of the water absorbent fiber pile part Y and the non-water absorbent fiber pile part U is 5 mm. The length of any pile can be, for example, about 2 to 30 mm, but preferably 3 to 10 mm.

  There is no particular limitation on the surface to be cleaned. For example, it can be suitably used for various surfaces of various furniture such as floor surfaces made of various materials such as wood, plastic, concrete, mortar, and tiles, tatami mats, and top surfaces of desks.

  When water is contained in the cleaning part C, the water absorbent fiber pile part Y of the cleaning part C mainly contains moisture, and the non-water absorbent fiber pile part U constituting the part other than the water absorbent fiber pile part Y in the cleaning part C is: Does not contain much moisture. When the surface to be cleaned such as the floor surface is wiped by the cleaning unit C, the frictional resistance acting between the cleaning unit C and the surface to be cleaned is large in the water absorbing fiber pile portion Y having a large ratio of moisture, and contains too much moisture. There is no small non-water-absorbing fiber pile part U. When the cleaning surface such as the floor surface is wiped by the cleaning portion C, the frictional resistance acting between the cleaning portion C and the surface to be cleaned is reduced in the non-water-absorbing fiber pile portion U provided over the entire cleaning portion C. Therefore, it is suitable for cleaning work.

  The water supply fiber pile portion Y, which is provided over the entire cleaning portion C and contains moisture, wipes off the dirt on the surface to be cleaned and separates the dirt stuck to the surface to be cleaned from the surface to be cleaned. Responsible mainly. Moreover, the non-water absorption fiber pile part U which does not contain the water | moisture content provided over the whole cleaning part C acts suitably about isolate | separating the stuck dirt from the to-be-cleaned surface in the state to which the water | moisture was supplied. Therefore, the water-absorbing fiber pile portion Y and the non-water-absorbing fiber pile portion U combine to exhibit an excellent cleaning effect. The cleaning section C is composed of a plurality of strip-shaped water absorbent fiber pile portions Y and a plurality of strip-shaped non-water absorbent fiber pile portions U which are alternately adjacent to each other in parallel. Separation action and dirt wiping and moisture supply action by the water absorbent fiber pile part Y, especially when the adjacent direction of the belt-like water absorbent fiber pile part Y and the belt-like non-water absorbent fiber pile part U is the main wiping direction of the cleaning part C The cleaning part C can be effectively exhibited throughout. Since both the water absorbent yarn pile that constitutes the water absorbent fiber pile portion Y and the non-water absorbent yarn pile that constitutes the non-water absorbent fiber pile portion U are loop piles, the sticking dirt is scraped off from the surface to be cleaned. Excellent separation effect.

  In addition, the main wiping direction is the main direction when wiping the surface to be cleaned with a cleaning cloth, and in the case of a shape (for example, a rectangle, a square, an ellipse, etc.) in which the longitudinal direction and the short direction perpendicular thereto are determined, Usually, it is a longitudinal direction or a transverse direction. Of these, the short direction in which the range to be wiped is wide is often the main direction. In the case of a shape such as a circle in which the longitudinal direction and the short direction are not determined, any direction can be used as the main wiping direction. If the holding mode is determined when the cleaning cloth is held on a cleaning cloth holding head or the like, the main wiping direction of the cleaning cloth is often determined.

  FIG. 3 is a schematic cross-sectional view of a cleaning cloth B as another example of the embodiment of the present invention. A schematic plan view of the cleaning cloth B is the same as FIG.

  In this case, the pile height from the front side surface of the sheet-like base S is 4.5 mm for the water absorbent fiber pile portion Y and 5 mm for the non-water absorbent fiber pile portion U1. That is, the height with respect to the sheet-like base portion S is higher in the non-water absorbent fiber pile portion U1 than in the water absorbent fiber pile portion Y, and the height of the non-water absorbent fiber pile portion U1 due to the pressing of the cleaning portion C against the surface to be cleaned during cleaning. Therefore, both the water absorbent fiber pile portion Y and the non-water absorbent fiber pile portion U1 can come into contact with the surface to be cleaned.

  In this case, the water-absorbing fiber pile portion Y can sufficiently supply moisture for wiping off the dirt on the surface to be cleaned and separating the dirt stuck to the surface to be cleaned from the surface to be cleaned. Reduction of the frictional resistance with the surface by the non-water absorbent fiber pile portion U1 and separation of dirt stuck to the surface to be cleaned by the non-water absorbent fiber pile portion U1 can be realized more effectively. The height with respect to the sheet-like base is preferably 0.2 to 2 mm higher in the non-water absorbent fiber pile than in the water absorbent fiber pile. More preferably, it is 0.4 to 1 mm.

  In any of the above cleaning cloths, the ratio of the area occupied by the water absorbent fiber pile part and the non-water absorbent fiber pile part in the cleaning part is the friction resistance reducing action by the non-water absorbent fiber pile part, the sticking dirt separating action, and the dirt by the water absorbent fiber pile part. It is preferably 3: 7 to 8: 2 for effectively wiping off and supplying water. More preferably, it is 4: 6 to 7: 3.

  Moreover, in the cleaning cloth of the present invention, as an aspect in which both the water absorbent fiber pile portion and the non-water absorbent fiber pile portion are provided over the entire cleaning portion C, a straight strip portion or a curved strip portion having a constant width or a variable width are alternately arranged. Repeating mode, when the cleaning cloth is square, both piles are inclined to the sides, or V-shaped strips, corrugated strips, zigzag strips, concentric strips, concentric ellipses A belt-like portion, a concentric polygonal belt-like portion, or the like can also be used. Both pile portions can be arranged in a checkered pattern, or the other pile portion can be dispersedly arranged in one pile portion. In addition, it is preferable that the water absorbent fiber pile portion and the non-water absorbent fiber pile portion are always or almost always alternately positioned in the main wiping direction of the cleaning portion.
