Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wiping cloth for cleaning and, more particularly, to a wiping cloth which can excel in dust removing ability and can easily grasp the state of wear.

[0002]

2. Description of the Related Art The present applicant has previously disclosed Japanese Patent Application Laid-Open No. H8-15488.
As disclosed in Japanese Patent Publication No. 1 (1993), a wiping sheet made of a nonwoven fabric made of ultra-fine fibers having a diameter of 1 to 9 μm and a base cloth having the necessary strength and thickness as a wiping cloth are integrally joined. A two-layered mop wipe was proposed.

This wiping cloth is an inexpensive and high-strength base cloth made of a microfiber wiping sheet which is superior in dust removing ability but is expensive and easily consumed, so that it is difficult to use it alone as a wiping cloth. By reinforcing it, it can be used effectively as a wiping cloth, and has the advantage that even microscopic dust at the bacterial level can be wiped without using a dusting agent.

On the other hand, in the wiping cloth, as described above, the wiping sheet made of ultra-fine fibers is liable to be consumed, and the wiping sheet is worn out and gradually loses its dust removing ability. Need to replace the wipe with a new one. In this case, since the wiping sheet made of ultra-fine fibers is expensive, it is desirable to replace the wiping sheet when the wiping sheet is completely worn out in consideration of economy.

[0005] However, depending on the relationship between the wiping sheet and the base cloth, even if the wiping sheet is worn out and the base cloth is exposed, it may be difficult to recognize the consumption state of the wiping sheet. For example, when the base cloth is made of the same non-woven fabric as the wiping sheet, even if the wiping sheet is worn and the base cloth is exposed, the surface of the base cloth is similarly frayed with a worn feeling. In such a case, the state of wear of the wiping sheet is often difficult to understand at a glance.

[0006]

SUMMARY OF THE INVENTION An object of the present invention is to provide a wiping cloth which can excel in dust-removing ability and can easily grasp the state of wear.

[0007]

According to the present invention, in order to solve the above-mentioned problems, a surface cloth made of non-woven fabric containing at least a part of ultra-fine fibers having a diameter of 1 to 9 μm has a thickness greater than that of the surface cloth. And a wiping cloth characterized in that the wiping cloth is attached integrally to at least one surface of a core material having high strength and flexibility, and the surface cloth is colored in a different hue from that of the core material.

[0008] In a specific embodiment of the present invention, the core material is
Whether it is composed of non-woven fabric consisting of fibers with a larger diameter than the surface cloth,
Or it is constituted by a sponge body.

The wiping cloth of the present invention having the above-mentioned structure has a very high dust-removing ability because it uses a surface cloth made of ultra-fine fibers having a diameter of 1 to 9 μm. Not only dust can be reliably removed, but also mites, pollen, and some of bacteria can be removed. Further, although the surface cloth itself has low strength, it is laminated with a core material having the necessary strength and thickness as a wiping cloth, so that the required strength can be maintained by being reinforced by the core material. At the same time, elasticity is also provided, and the usability is improved.

[0010] Even if the surface cloth is worn out, the wiping cloth exerts dust-removing ability as long as at least some of the ultra-fine fibers remain, so that it is effectively used until the ultra-fine fibers are completely consumed. be able to. In this case, since the surface cloth and the core material are colored in different hues, the microfibers partially disappear by the wiping cloth being worn out, and even if the core material is exposed, even if the core material is exposed, a different color core is exposed. The consumption state of the wiping cloth can be easily understood by comparison with the material, and even when only a very small amount of ultrafine fibers remains, it can be easily and reliably grasped. Therefore, the wiping cloth can be used until the surface cloth is completely consumed, which is very economical.

[0011]

FIG. 1 shows a first embodiment of a wiping cloth according to the present invention. This wiping cloth 1A is composed of a surface cloth 2 made of non-woven fabric containing ultra-fine fibers having a diameter of 1 to 9 .mu.m, and the surface cloth 2A. A flexible core material 3 having a thickness and strength greater than 2 is integrally joined by means such as adhesion or sewing, and the surface cloth 2 and the core material 3 are combined with each other, for example, in green and yellow. These are colored in different hues.

The fibers constituting the surface cloth 2 may be lipophilic fibers such as polypropylene, polyester or acrylic, or hydrophilic fibers such as rayon or nylon (trade name). The lipophilic fiber and the hydrophilic fiber may be mixed at an appropriate ratio. When a mixture of lipophilic fibers and hydrophilic fibers is used, even water-based stains and oil-based stains can be reliably wiped off. The fibers constituting the surface cloth 2 may be all ultrafine fibers as described above, but the ultrafine fibers are partially used, and the remaining ultrafine fibers having a larger fiber diameter are used. (10 to 30 μm) can also be used.

The core member 3 may be made of any material as long as it is thicker, stronger and more flexible than the surface cloth 2, but is preferably a woven or non-woven fabric. Alternatively, a sponge body is used, and in the illustrated embodiment, a nonwoven fabric is used. This non-woven fabric
It is desirable that the surface cloth 2 be composed of fibers having a larger diameter.

The wiping cloth 1A having the above structure is used for cleaning furniture, floors, etc. by holding it directly in the hand or mounting it on the head of a mop, and the surface cloth 2 has a diameter of 1 to 9 μm.
Because it is made of ultra-fine fibers, it excels in dust-removing ability, it can reliably remove even fine dust without impregnating with dusting agents, as well as mites, pollen and some bacteria Etc. can also be removed.

Further, the surface cloth 2 made of ultrafine fibers
Although is excellent in dust removal ability, it has low strength, but is reinforced by lamination with the core material 3 to increase strength, and has an appropriate thickness and elasticity to give a good feeling of use.

The dirty wiping cloth 1A is washed with water and used repeatedly. The surface cloth 2 having a low strength gradually wears out and wears out during repeated use. However, as long as a very small amount of the ultrafine fibers remain, the surface cloth 2 exerts a dust removing ability. Until it is consumed, it can be used effectively. In this case, since the surface cloth 2 and the core material 3 are colored in different hues, when the surface cloth 2 is worn and the core material 3 is exposed, the different color core material 3 is exposed.
By contrast, the state of consumption of the surface cloth 2 becomes easier to understand, and even when only a very small amount of ultrafine fibers remains, it can be easily and reliably grasped. Therefore, the wiping cloth can be used until the surface cloth 2 is completely consumed, which is very economical.

FIG. 2 shows a second embodiment of the present invention.
The wiping cloth 1B of the second embodiment is obtained by bonding surface cloths 2a and 2b to both surfaces of a core material 3. In this case, the two surface cloths 2a and 2b may have the same configuration, but the fiber diameters may be different from each other, or one of the surface cloths 2a may be made of hydrophilic fiber and the other surface cloth 2b may be made of hydrophobic fiber. The configuration may be different from each other, such as a configuration using fibers. The two surface cloths 2a and 2b may be of the same color, but may be colored in different hues.
When the configuration of the two surface cloths 2a and 2b is different, it is effective to color them differently in order to identify them.

[0018]

As described above, the wiping cloth of the present invention has a diameter of 1
By attaching a nonwoven surface cloth containing at least a portion of ultra-fine fibers of about 9 μm to at least one surface of a flexible core material having a thickness and strength greater than that of the surface cloth, the dust removal ability can be improved. However, a nonwoven fabric made of ultra-fine fibers, which is expensive and easily consumed, can be effectively used for cleaning, and it is possible to wipe out even microbial-level fine dust without using a dusting agent. Further, by coloring the surface cloth and the core material to colors of different hues from each other, when the core material is exposed by the surface cloth being worn out, it becomes easy to understand the consumption state of the surface cloth by comparing the colors, Even when only a very small amount of ultrafine fiber remains, it can be easily and reliably grasped. Therefore, the wiping cloth can be used until the surface cloth is completely consumed, which is very economical.
