Description

  The present invention relates to a carpet cleaning material for wiping carpet dirt by wiping the carpet in a wet state.

  2. Description of the Related Art Conventionally, a cleaning tool that holds a nonwoven fabric as a cleaning member between nonwoven fabric holding heads connected to a handle and wipes the floor surface in a mop-like manner has been widely used.

  However, when a flat surface to be cleaned is wiped with this type of conventional cleaning tool, both ends in the moving direction of the cleaning tool of the nonwoven fabric covering the bottom surface of the nonwoven fabric holding head will be wiped off intensively, and the cleaning efficiency In addition, there is a tendency that the reduction of the cleaning member is quick, and the cleaning member is forced to be replaced with another cleaning member without effectively using most of the cleaning member.

  In addition, if the dust on the object to be cleaned becomes relatively large, it becomes difficult to wipe it off with the nonwoven fabric, so other means are required to remove it, and work efficiency is not good.

  In Patent Document 1, it is used for home use and business use when removing and removing floor stains, cleaning the floor, and cleaning the floor such as floor protection. An invention of a cleaning sheet for wet cleaning that does not occur is disclosed.

  That is, the cleaning in a cleaning tool including a cleaning unit and a rod-like handle connected to the cleaning unit, and the cleaning unit is provided with a sheet holding unit for fitting and holding both sides of the sheet. A liquid-permeable top sheet, a liquid-impermeable mounting sheet in contact with the cleaning section, and a surface sheet and the mounting sheet. The holding force x (g) of the sheet holding part is 10 g or more, and the holding force x and the coefficient of static friction y (tan θ) when attached to the cleaning part of the attached sheet, Is a cleaning sheet characterized by having a relationship represented by a predetermined relational expression.

  However, the object to be cleaned is the floor. Since the surface sheet to be brought into contact with the object to be cleaned is moisture-resistant paper, when the carpet is wiped, it is torn in a short period due to friction with a pile such as a cut pile. Further, since the friction with the carpet is large, there is a possibility that the sheet may be repeated when used while being held in the sheet holding portion.

  Further, in the case of a nonwoven fabric for floor dry wiping generally used conventionally, the fibers are not fixed in order to make the dust as easy as possible to be entangled, there are many gaps, and the surface is fluffy. For this reason, when the carpet is wiped, it is also torn or greatly stretched in a short period due to friction with a pile such as a cut pile and becomes unusable. In addition, since the friction with the carpet is larger, there is a possibility that the sheet may be repeated unless it is pressed firmly when used while being held on the sheet holding portion.

Japanese Patent Laid-Open No. 9-253017

  The present invention has been made in view of the above-mentioned problems existing in the prior art, and the object of the present invention is to provide smoothness and durability in cleaning work for wiping the carpet. It is an object of the present invention to provide a carpet cleaning material capable of wiping off dirt and dust on a carpet by wiping in a wet state.

The carpet cleaning material of the present invention that achieves the above object is as follows.
A cleaning material in which a water retention layer is laminated on the back side of a non-woven fabric or wet paper resistant water permeable layer having a basis weight of 5 to 80 g / m ²
The water-permeable layer has fibers fixed substantially at least on the front side, and has water-based liquid permeability in the thickness direction,
The water retaining layer holds the aqueous liquid and absorbs the aqueous liquid while supplying the aqueous liquid onto the carpet through the water permeable layer.
It is for wiping the carpet on the front side of the water-permeable layer in a state where the water-based liquid is held in the water-retaining layer, thereby wiping the carpet dirt.

When this carpet cleaning material is used and the water-based liquid is held in the water-retaining layer, it is held on a holding body such as a holding plate with a handle and the carpet is wiped on the front side of the water-permeable layer. Is a thin layer of nonwoven fabric or moisture-resistant paper with a basis weight of 5 to 80 g / m ² and has water-based liquid permeability in the thickness direction. The water-based liquid can be supplied to the carpet through the water-permeable layer and absorbed. The water-based liquid supplied onto the carpet is in a state accompanied by dirt or dust on the carpet due to dissolution or dispersion, etc., and the water-based liquid accompanied by dirt or dust in this way is transferred to the water retaining layer through the water permeable layer. It will be absorbed and wiped off. However, not all of the dust accompanying the aqueous liquid is absorbed by the water retention layer.

  At least on the front side of the water-permeable layer, the fibers are almost fixed, so when wiping on the carpet (for example, on the cut pile in a cut pile carpet), the frictional resistance is small and the sheet itself or the sheet is held on the holding plate. In the case of wiping, the holding plate in the state where the sheet is held may be repeatedly damaged due to the frictional resistance with the carpet, or the sheet may be stretched or torn due to the frictional resistance with the carpet. Is prevented. Therefore, the carpet cleaning material has smoothness and durability in cleaning work for wiping the carpet.

  The cleaning material for carpet according to the present invention has smoothness and durability in cleaning work for wiping the carpet. It is possible to wipe off the aqueous liquid accompanied by dirt or dust on the carpet while supplying the aqueous liquid.

An embodiment of the present invention will be described.
In the carpet cleaning material of the present invention, for example, water, negative ion water such as sodium bicarbonate electrolyzed water, an aqueous solution containing a cleaning agent, or other aqueous liquid (preferably an aqueous liquid suitable for wiping carpet dirt). In order to improve drying properties, an appropriate amount of a volatile component such as ethanol can be contained.), For example, the lower surface of the holding plate in a wiping and cleaning tool in which a handle is connected to a flat rectangular holding plate On the side, with the front side of the water permeable layer facing downward, and holding the end part on the holding part on the upper surface side of the holding plate (for example, the holding part that holds the end part between the tips of the elastic tongue pieces) It is for wiping off dirt on the carpet by wiping on various carpets such as cut piles and loop piles on the front side of the water-permeable layer (or by holding on other holding tools).

The carpet cleaning material of the present invention is a cleaning material in which a water-retaining layer is laminated on the back side of a non-woven fabric or wet paper-resistant water-permeable layer having a basis weight of 5 to 80 g / m ² (preferably 5 to 20 g / m ² ). . In addition, a water permeable layer may be laminated on both sides of the water retention layer. In this case, the carpet can be wiped on the front side of both water-permeable layers.

  In the water permeable layer, the fibers are substantially fixed at least on the front side (preferably substantially in the thickness direction). The fibers constituting the water permeable layer may be only hydrophobic fibers, but may include hydrophilic fibers.

  This water-permeable layer is preferably a non-woven or wet-resistant paper-like material in which fibers are substantially fixed at least on the front side (for example, fixing by fusing of fibers or bonding of fibers with an adhesive), and there is almost no fuzz. It can be a layer (for example, a non-woven or wet paper-like layer made of polyethylene terephthalate fiber or polypropylene fiber). In this case, the water-permeable layer has fibers fixed substantially at least on the front side, and has almost no fuzz. Prepare. In order to reduce the frictional resistance, a fluororesin fiber can also be used.

  This water-permeable layer can be a layer made of a spunbonded nonwoven fabric (for example, made of polyethylene terephthalate fiber or polypropylene fiber). In this case, the fibers are fused and fixed by a hot press in a state where the fibers are entangled, and there is almost no fuzzing. Therefore, when wiping the carpet, the frictional resistance is small, and further smoothness and durability are provided for the carpet cleaning work. As an example of such a spunbonded nonwoven fabric, there can be mentioned various top weights made of polyethylene terephthalate or polypropylene fiber (trade name of spunbonded nonwoven fabric manufactured by Nippon Nonwoven Fabric Co., Ltd.). As another nonwoven fabric which can comprise a water-permeable layer, the thermal bond nonwoven fabric and airlaid nonwoven fabric which gave the strong heat press can be mentioned, for example.

  The water permeable layer has water-based liquid permeability in the thickness direction.

  For example, the water permeable layer may be provided with a small permeable portion in the thickness direction through which the aqueous liquid permeates. In this case, the water-based liquid permeates in the thickness direction mainly through the small permeable portion in the thickness direction provided evenly in the water permeable layer.

  Further, the small transmission part can be a small hole in which a porous thin film is formed. In this case, the aqueous liquid permeates in the thickness direction mainly through the porous thin film in the small permeation portion, which is a small hole in the thickness direction provided uniformly in the water permeable layer. The small transmission part can also be a through hole.

  The water retention layer holds the aqueous liquid and absorbs the aqueous liquid while supplying the aqueous liquid onto the carpet via the water permeable layer.

This water retention layer can be mainly composed of a fiber material containing hydrophilic fibers (for example, rayon fibers, cotton fibers, etc.). Fibers other than hydrophilic fibers such as hydrophobic fibers may be included. The basis weight can be, for example, 20 to 200 g / m ² (preferably 30 to 80 g / m ² ).

  Such a water-retaining layer can be a water-absorbing nonwoven fabric layer. Examples of such a water-absorbing non-woven fabric include a non-woven fabric of 70 to 100% by weight of rayon and 30 to 0% by weight of polyester.

  Moreover, a part of the fiber material which comprises a water retention layer penetrate | invades into a water permeable layer, and a water permeable layer and a water retention layer can be combined.
