Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wiping sheet and a wiping method.

[0002]

2. Description of the Related Art Various nonwoven fabrics are used for cleaning floors and various kinds of furniture. However, the conventional nonwoven fabric cannot provide a sufficient cleaning effect in cleaning to remove dirt stuck to window glass or the like, or in cleaning a mesh of a screen door.

[0003] In particular, in order to clean a mesh body in a screen door, not only can such a nonwoven fabric be used to clean well, but also an effective cleaning method that can be performed in ordinary households besides removing the screen door and directly washing it with water. The task of removing the doors one by one and washing them in the right place was as complicated as a large screen door.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems in the prior art, and has as its object to remove dirt such as dust from an object to be cleaned and to provide a cleaning fiber. A wiping sheet body and a wiping method that can be effectively cleaned by being taken between bodies or adhered to or absorbed by a cleaning fiber body, and particularly capable of effectively cleaning a mesh body. Is to provide.

[0005]

According to the present invention, there is provided a wiping sheet according to the present invention, in which at least a part or all of at least one surface of a sheet-like substrate is projected into a single-fiber-like cleaning fiber. Are provided in a group, and the cleaning-use fiber bodies are self-standing in a state of being erected from the base to the tip.

The wiping method according to the present invention is characterized in that an object to be cleaned is wiped by a cleaning section of the wiping sheet. The object to be cleaned can be wiped dry.
By attaching or including a cleaning liquid or water to one or both of the cleaning processing unit and the cleaning target, the cleaning target can be wiped with the cleaning liquid or water interposed. Objects to be cleaned can be window glasses, floors, walls, ceilings, baths, around kitchens, various furniture, appliances, screen nets (mesh for insect repelling), meshes such as interior and exterior of automobiles, etc. ,
There is no particular limitation. The cleaning processing unit has a large number of cleaning fiber bodies protruding from the sheet-like substrate in a group, and each of the cleaning fiber bodies forms a self-standing single fiber in a state of standing from the base to the tip. Therefore, when the cleaning target is wiped and cleaned by the cleaning processing unit, dirt such as dust on the cleaning target is scraped off by the aggregate of the cleaning processing fiber bodies as described above, and the cleaning processing fiber bodies are separated from each other. During the cleaning, the cleaning fiber is adhered to or absorbed by the cleaning fibrous body (provided that the cleaning fibrous body has water absorbency in the presence of an aqueous liquid), so that the cleaning is effectively performed. Since the wiping sheet has a sheet shape and the cleaning section has a large number of the above-mentioned cleaning fibers in a group, a high cleaning effect can be achieved in cleaning a mesh or a surface having irregularities.

Further, it is possible to enhance the cleaning effect by wiping the object to be cleaned with a cleaning liquid or water depending on the type of the part to be cleaned and the degree of contamination. For example, in cleaning the mesh body, the cleaning effect can be further enhanced by interposing a cleaning liquid. In addition, examples of the cleaning liquid include an aqueous cleaning liquid containing a surfactant.

The upright angle of the cleaning fiber in the wiping sheet of the present invention with respect to the sheet substrate at the leading end (the angle between one surface of the sheet substrate and the axis of the cleaning fiber) is 60. 6% or more
It is preferably 0% or more. In order for the dirt such as dust on the object to be cleaned to be more reliably scraped off by the aggregate of the cleaning fiber, the rising angle is preferably 70 degrees or more, and the ratio is 70 or 80. % Is preferable. More preferably, the standing angle is 70 degrees or more and the ratio is 70 or 80% or more.

The projection height of the cleaning fiber can be, for example, 0.1 mm to 10 mm. Preferably 0.2 to 1 mm, more preferably 0.3 to 0.8
mm, more preferably 0.4 to 0.6 mm. When wiping the screen mesh for household use with a cleaning solution or water, the projection height of the cleaning fiber is preferably about 0.3 to 0.8 mm, and 0.4
About 0.6 mm is more preferable.

As the cleaning fiber, for example, a 0.5-65 denier monofilament fiber can be used, and it can be selected according to the cleaning application. Examples of the cleaning fiber include synthetic fibers or semi-synthetic fibers such as nylon, polyester, polypropylene, rayon, and acetate, and various natural fibers such as cotton and silk.

[0011] density per unit area of the cleaning process for the fiber body protruding from the sheet substrate in the cleaning process unit, for example, be a 40 g / ^{m 2} to 300 g / ^{m 2} approximately.

The cleaning fiber may be water-absorbing or non-water-absorbing, or both may be used together. In order to wipe off the dirt by wiping the object to be cleaned with a cleaning liquid or water therebetween, and to make the dirt effectively adhere to or be absorbed by the fibrous body for cleaning processing, the fibrous body for cleaning processing is used. It is desirable to use one having water absorbency. The same applies to the case of using for wiping moisture from the object to be cleaned. Examples of the absorbent fiber for cleaning treatment include rayon, acetate, cotton, silk and the like. In addition, when a non-water-absorbing fibrous body for cleaning treatment is used, the effect of scraping dirt or the like is hardly reduced even in the presence of an aqueous liquid.

[0013] The projection height, denier,
The type of water-absorbing / non-water-absorbing, hard / soft, material, etc. can be selected according to the object to be cleaned and the cleaning application (removal of sticky dirt, dust removal, polishing, polishing, etc.). It is most common that the type of such a fiber body for cleaning treatment is constant or substantially constant. For example, a part or all of at least one surface of the sheet-like substrate is divided into plural kinds of sections. ,
For each type of section, the type of cleaning fiber body (projection height, denier, water-absorbing / non-water-absorbing, hard / soft,
One or more of the materials) may be different. Such a section may be, for example, partitioned into parallel stripes, or may be partitioned into a checkered pattern or a diamond lattice. Also, two or more types of cleaning fiber bodies may be mixed and dispersed in the entire or a part of the cleaning processing unit. With this configuration, a wiping sheet having the characteristics of two or more types of cleaning fibers can be obtained.

It is preferable that the sheet-like substrate has a flexible sheet shape. In this case, it is suitable for wiping the object to be cleaned having a protrusion or a concave portion or the object to be cleaned located in a narrow place by the cleaning processing unit. The sheet-like substrate may be mainly composed of a sheet-like material such as a nonwoven fabric, a synthetic resin sheet, a woven fabric, or paper. In addition, the sheet-like substrate is preferably non-water-soluble in wiping an object to be cleaned with a cleaning liquid or water, wiping off moisture, or washing and using it multiple times. In addition, it can be made impermeable to the front and back directions.

The wiping sheet of the present invention preferably has an embedding / fixing layer in which the base of the cleaning fiber is embedded and fixed in an upright state on the sheet-like substrate. Since the base of the cleaning fiber body is in an upright state in the embedding and fixing layer and is embedded and fixed in that state, the self-sustainability of the cleaning fiber body protruding from the sheet-like substrate in the upright state is maintained. And the dirt such as dust on the object to be cleaned is more reliably scraped off by the aggregate of the cleaning fiber bodies.

In this case, the embedding and fixing layer is required to be able to maintain and fix the base of the cleaning treatment fiber body in its upright posture. It is preferred that Such an embedding fixed layer can be made of, for example, a synthetic resin.

Further, it is preferable that the cleaning treatment fiber body directly protrudes from the embedded fixing layer. The self-sustainability of the cleaning fiber protruding from the sheet-like substrate in the standing state is high, and dirt such as dust on the object to be cleaned is more reliably scraped off by the assembly of the cleaning fiber. Because you can do it.

In these cases, the fibrous body for cleaning treatment may be implanted in the embedding / fixing layer with the base portion standing upright and implanted. Such flocking is
The cleaning can be performed by flocking the sheet-like substrate with a cleaning fiber body by flocking. Such a flocking process is, for example, providing a synthetic resin adhesive layer on one surface of a non-woven fabric or the like that is the main body of the sheet-like substrate to serve as a negative electrode, and above that, a positive electrode having a large number of piles for flocking is positioned, The positively charged pile is dropped on the synthetic resin adhesive layer in an upright state, and the base of each pile is embedded in the synthetic resin adhesive layer, and then the synthetic resin adhesive layer is solidified to erect the base of the cleaning fiber body. It can be carried out by embedding and fixing in a synthetic resin adhesive layer (embedding fixing layer) in this state.

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

FIGS. 1 to 3 show a wiping sheet as an example of an embodiment of the present invention.
FIG. 1 is a schematic sectional view of a wiping sheet body, FIG. 2 is a plan view thereof, and FIG. 3 is an explanatory view showing a manufacturing method thereof.

The wiping sheet A is composed of a nonwoven fabric 10 made of a non-water-absorbing synthetic fiber and an embedding and fixing layer made of a water-insoluble and water-impermeable synthetic resin provided on the upper surface of the nonwoven fabric 10 in FIG. Over the entire surface of the embedding and fixing layer 12 in the flexible sheet-like substrate 14 made of 12, the bases of a large number of water-absorbing cleaning fiber bodies 16 (rayon single fibers) are embedded and fixed in an upright state. A portion extending over the entire surface of the embedding and fixing layer 12 is a cleaning processing section B having a large number of protruding cleaning fiber bodies 16 in a group.
Respectively project directly from the embedding and fixing layer 12 and stand upright from the base to the tip.

In these cleaning fiber bodies 16, the ratio of the upright angle with respect to the sheet-like substrate 14 at the leading end portion of 70 ° or more is 80% or more. Although the rayon single fiber having a length of 0.6 mm is used as the cleaning fiber 16, it is not limited to this. The protrusion height of the cleaning treatment fiber body 16 is 0.4 to 0.5 mm.

The flocking of the cleaning fiber 16 can be performed on the sheet-like substrate 14 by flocking as shown in FIG. That is, a synthetic resin adhesive layer is disposed on the upper surface of the nonwoven fabric 10, which is the main body of the sheet-like substrate 14, to serve as a negative electrode, and a positive electrode 18 having a large number of cleaning fiber bodies 16 (pile) for flocking is positioned above the negative electrode. Then, the cleaning fiber 16 positively charged is dropped on the synthetic resin adhesive layer in an upright state, and each cleaning fiber 1 is cleaned.
6 is embedded in the synthetic resin adhesive layer, and then the synthetic resin adhesive layer is solidified, and the base of the cleaning fiber body 16 is embedded and fixed in the synthetic resin embedded fixing layer 12 in an upright state. Can be implemented.

When the object to be cleaned is wiped by the cleaning processing section B in the cleaning sheet A, window glass, floor, various furniture, electric appliances, screen net (net for insect repelling), interior and exterior of an automobile, etc. It is also possible to wipe the object to be cleaned such as a mesh body in a dry state, and to attach or include the cleaning liquid or water to one or both of the cleaning processing unit B and the object to be cleaned, thereby cleaning the object to be cleaned. Alternatively, it can be wiped with water.

The cleaning section B has a large number of cleaning fibers 16 directly protruding from the embedding and fixing layer 12 of the sheet-like substrate 14 in a group. It is a single fiber that is self-supported in a state of standing up to the tip as described above. Therefore, when the cleaning target is wiped by the cleaning processing unit B, dirt such as dust on the cleaning target is scraped off by the aggregate of the cleaning processing fiber bodies 16 and the cleaning processing fiber bodies 16 are separated from each other. Taken in between,
Alternatively, it is attached to or absorbed by the cleaning fiber 16 (but in the presence of an aqueous liquid), so that the cleaning is effectively performed. Since the wiping sheet body A has a flexible sheet shape and the cleaning processing section B has a large number of the cleaning processing fiber bodies 16 as described above, the cleaning processing section B has high cleaning performance in cleaning a mesh body or a surface having irregularities. This is advantageous in that the cleaning processing unit B wipes the object to be cleaned having a projection or a concave portion or the object to be cleaned located in a narrow place, while having an effect.

Further, the cleaning effect can be enhanced by wiping the object to be cleaned with a cleaning liquid or water depending on the type of the part to be cleaned and the degree of contamination. For example, in cleaning the mesh body, the cleaning effect can be further enhanced by interposing a cleaning liquid. In particular, since the cleaning fiber 16 has water absorbency, when the object to be cleaned is wiped with a cleaning liquid or water, the dirt is effectively attached to the cleaning fiber 16 while the dirt is scraped off. Or is absorbed. In addition, examples of the cleaning liquid include an aqueous cleaning liquid containing a surfactant.

FIG. 4 is a plan view of another wiping sheet A as an embodiment of the present invention.

In this example, the cleaning section B is divided into stripes by parallel straight lines, and the water-absorbing cleaning fiber 16 is formed.
Water-absorbing sections C having (rayon single fibers) and non-water-absorbing sections D having non-cleaning treatment fiber bodies 16 (nylon single fibers) are alternately arranged. In this case, by wiping with a cleaning solution or water, the water-absorbing cleaning fiber 1
In the water-absorbing section C having the non-cleaning fiber 16, the dirt is effectively adhered to or absorbed by the cleaning fiber 16 while the dirt is scraped off. In this case, the effect of scraping off dirt or the like even in the presence of an aqueous liquid is unlikely to decrease.
