Description

The present invention relates to the structure of a towel or handkerchief (collectively referred to as a towel in the present invention) for wiping the face, hands or body.

Towels are used in sports and general social life to wipe wet hands and bodies, dirt on hands and bodies, and to wipe wet faces and sweat on the face. In this case, pathogens such as viruses and bacteria adhering to the hands and body surface invade the body through the mucous membranes of the mouth, eyes, and nose through a towel when the sweat and dirt on the face are subsequently wiped and infected. May cause illness. In Patent Document 1, as a waterproof moisture-absorbing quick-drying material that can be applied to towels, two layers of a water-absorbing quick-drying material and a brushed material are laminated, and a waterproof material is provided on the outer surface of the water-absorbing quick-drying material. It is described that the coating is processed so that one side is waterproof and the other side is moisture-absorbing and quick-drying.

JP-A-9-141775

The waterproof, moisture-absorbing and quick-drying material described in Patent Document 1 coats the outer surface with a waterproof material to prevent water from entering from the outside, and also prevents stuffiness on the side where the skin touches, and as a towel. When used, it wipes the hands and face on the same surface on the inside and does not effectively prevent the invasion of pathogens into the mucous membranes.

The present invention has been made in view of the above, and provides a towel for controlling the movement of pathogens by interposing a waterproof material between two layers, one for a material for wiping hands and body and the other for wiping a face. be.

The towel according to the present invention is a waterproof sheet sandwiched between a first flat material for wiping the face, a second flat material for wiping hands and body, and the first and second materials. And are laminated together. According to the present invention, pathogens such as viruses are prevented from passing through the tarpaulin in the thickness direction and moving from the second material to the first material. In addition, by providing the first and second materials on both sides of the towel, the hands and body come into contact with the second material when using the towel, but they do not come into contact with the first material, and the face uses the towel. They can be used separately so that they sometimes come into contact with the first material. Therefore, even if a pathogen such as a virus adhering to the hand or body moves to the second material of the towel when wiping the hand or body and adheres, the pathogen changes from the second material to the first material. It does not transfer and prevents pathogens from adhering to the face from the first material and causing infection when wiping the face with a towel.

Further, the first and second materials have a form that can be distinguished from each other. According to this configuration, it is possible to easily identify which material side is for face wiping.

Further, at least the surfaces of the first and second materials are colored in different colors. According to this configuration, it is easy to identify whether the face is on the wiping side just by looking at the color.

Further, the waterproof sheet is a waterproof / breathable material, and has moisture permeability from the first material to the second material. According to this configuration, the difficulty of drying is eliminated.

Further, the first and second materials and the waterproof sheet have the same surface shape and are integrally sewn at the end edges in a laminated state. This configuration facilitates the manufacturing process.

Further, in the present invention, the high friction material may be provided in a distributed manner between the waterproof sheet and the first and second materials. According to this configuration, the positional deviation in the surface direction between the waterproof sheet and the first and second materials can be eliminated, and the operability is maintained.

According to the present invention, it is possible to provide a towel in which a pathogen attached to a hand or a body does not adhere to the face when wiping the face.

It is a figure explaining the structure of the towel which concerns on this invention, (A) is an exploded perspective view, (B) is a vertical sectional view of an edge portion. It is a figure which shows an example of how to use a towel, and is the state at the time of wiping a hand other than a face and a body. It is a vertical cross-sectional part enlarged view which shows an example of a waterproof sheet. It is a chart which shows the result of the infection prevention effect confirmation experiment.

1A and 1B are views for explaining the structure of the towel 1 according to the present invention, where FIG. 1A is an exploded perspective view and FIG. 1B is a vertical sectional view of an edge portion. In FIG. 1, the towel 1 has a two-layer structure of a flat-shaped, for example, rectangular towel material 10 and a towel material 20 having the same flat shape as the towel material 10, and further, the towel material 10 and the towel material 20. It is provided with at least one waterproof sheet 30 having the same planar shape sandwiched between the two. The towel materials 10 and 20 and the waterproof sheet 30 are integrated as shown in FIG. 1 (B) in a laminated state. That is, the towel materials 10 and 20 and the waterproof sheet 30 in the laminated state are sandwiched by the bias tape 40 having a predetermined width along the edge edges of the four peripheral edges as shown in FIG. 1 (B). In this state, use a sewing machine (not shown) to sew with thread 50 and perform edging.

In the present embodiment, the towel material 10 is the front side, that is, the surface for wiping the face. In the present embodiment, the towel material 20 is the back side, that is, the surface on which the hand or body is wiped. The towel materials 10 and 20 have at least a surface that identifies one of them. As the identification form, for example, the outer surface of the towel material 10 is colored green, the outer surface of the towel material 20 is colored red (or yellow), or the outer surface of the towel material 20 is indicated by a different pattern, character, or mark other than the color. , The surface condition may be different.

The towel materials 10 and 20 may be known water-absorbent towel cloths and gauze cloths, and may be fibers or non-woven fabrics. Further, the towel materials 10 and 20 may be the same material or different materials. The towel material 10 is for wiping the face and is soft to the touch, and a material suitable for wiping sweat on the face and removing stains is applied. A material suitable for dropping may be applied.

The waterproof sheet 30 may be made of polyvinyl chloride (PVC) or a waterproof and easily deformable resin material containing polyethylene terephthalate (PET) and nylon (registered trademark). Further, the waterproof sheet 30 may be a waterproof / breathable material having a multi-layer structure under the trade name Gore-Tex (registered trademark) and blocking the passage of moisture while allowing water vapor to pass therethrough. It is known that the moisture-permeable material does not allow pathogens of about 10 microns or more such as viruses to pass through, and there is no problem in using it. Further, the towel 1 has a two-layer structure and is difficult to dry by sandwiching the waterproof sheet 30, but by using a waterproof / breathable material as the waterproof sheet 30, the difficulty of drying can be eliminated. The waterproof sheet 30 is usually represented by water pressure resistance and moisture permeability, and generally, water resistance 3,000 mm to 50,000 mm JIS L 1092B (high water pressure method), moisture permeability 3-5,000 g JIS L 1099A-1 method, 10-30,000g JISL1099B-1 method, the larger the water resistance value and the smaller the moisture permeability value, the higher the waterproof property.

FIG. 2 is a diagram showing an example of how to use the towel 1, and is a diagram showing a state when the hands and body other than the face are wiped. When wiping the hands or body other than the face, fold the towel material 20 in half so that it is on the outside, and hold one side of both outer surfaces of the towel 1 with your hands, as shown in FIG. You will wipe your hands and body on the other side. As a result, the towel material 10 side is not touched when wiping the hands or body. Further, when wiping the face, the whole may be spread out, the towel material 20 side may be grasped with both hands, and the face of the towel material 10 may be directed to the face side to wipe the face. As a result, the hand does not touch the towel material 10 side even when wiping the face.

Further, since the waterproof sheet 30 is integrally sewn at the peripheral edges of the towel materials 10 and 20, the towel material 10 and the towel material 20 are displaced in the surface direction during hand wiping and face wiping, and are operated. It may be difficult. Therefore, before sewing, a high-friction material is placed at an appropriate position on both sides of the waterproof sheet 30 or on the entire surface, for example, an adhesive or an adhesive is applied, and a hook-and-loop fastener or the like is placed to arrange the towel materials 10, 20. It is preferable to strengthen the adhesion or bonding with and to prevent the occurrence of the misalignment. It is preferable that the towel materials 10, 20, the waterproof sheet 30, the adhesive, and the like are made of a material that does not easily lose its shape even after being washed many times, does not easily deteriorate in performance, and has a long life.

The shape of the towel 1 is not limited to a rectangle, and a circular shape or any other shape suitable for the intended use can be adopted. Further, regarding the size and thickness, an appropriate size and thickness can be adopted according to the application.

<Experimental example>

In addition, each mark appearing immediately above the numerical values "1" to "6" on the left and right sides of FIG. 4 indicates the presence or absence of cDNA detection, and if it is detected, it is indicated in white and detected. If not, it is shown as colorless.

First, in the test result when "cDNA is dropped on the front towel", first, as a premise, the DM (distilled water) of "1" is tested, and it is confirmed that the DM does not contain cDNA. Then, in "2", the detection for the undiluted cDNA solution (8ngtRNA equivalent) was confirmed.

In "3", cDNA was detected in the front towel material for the comparative example work without the tarpaulin. In "4", cDNA was detected in the back towel material for the comparative example work. In "5", cDNA was detected in the front towel material for the example work with the waterproof sheet. On the other hand, in "6", cDNA was not detected in the back towel material for the example work. Therefore, in the example work, it was found that the cDNA dropped on the front surface was prevented from passing through the waterproof sheet.

Next, in the test result when "cDNA is dropped on the back towel", the same as above, the test for DM (distilled water) of "1" is performed, and it is found that the DM does not contain cDNA. Confirmation was performed, and then, at "2", detection for the undiluted cDNA solution (8ngtRNA equivalent) was confirmed.

Subsequently, in "3", cDNA was detected from the front towel material for the comparative example work without the tarpaulin. In "4", cDNA was detected in the back towel material for the comparative example work. In "5", cDNA was not detected in the front towel material for the example work with the waterproof sheet. On the other hand, in "6", cDNA was detected in the back towel material for the example work. Therefore, in the example work, it was found that the cDNA dropped on the back surface was prevented from passing through the waterproof sheet. Furthermore, it was confirmed that even when a waterproof / breathable material was applied as the waterproof sheet, the passage of cDNA could be blocked regardless of the orientation between the fabric and the non-porous membrane.

From this, it was shown that in the towel for infection prevention corresponding to the present invention, nucleic acid did not pass (could be blocked) from the towel material on the back surface to the towel material on the front surface, and virus infection was performed. It was confirmed that it is effective in preventing the virus.
