2. Description of the Related Art Conventionally, the problems to be solved by the invention
As the antistatic sheet, there is a sheet described in Japanese Patent Application Laid-Open No. 2-267893 filed by the applicant earlier. As shown in FIG. 6, this sheet 1 is made of paper by adding conductive short fibers, and is provided with a discharge paper 2 in which a part of the conductive short fibers is projected from the paper surface. The static electricity charged on the human body was quickly absorbed by the paper 2 and discharged in the air.

However, the above-mentioned antistatic sheet is used in front of a carpet laid in a room, a chair mat for operating a computer, a floor mat laid at the entrance and exit of a room, an entrance mat, and an opening / closing door in an elevator or an elevator hall. When used as a floor mat to be laid, a mat to be laid indoors in cars, trains, airplanes, etc., carpets, wall materials, etc., mites will be generated in a place kept at an appropriate temperature and humidity. Therefore, there is a problem in that the human body is uncomfortable and a special illness such as allergy is transmitted.

Under these circumstances, it has been attempted to spray or apply a miticide on the sheet or to inject the miticide against the inside of the sheet with respect to the occurrence of mites. However, in all cases, the effect is temporary, and the effect disappears with the passage of time or by cleaning, and there is a problem that the effect cannot be maintained for a long period of time.

The present invention provides an antistatic insect repellent sheet which has both excellent static eliminating effect and insect repellent effect, and is capable of resolving the trouble caused by static electricity, the occurrence of mites and the trouble caused by reproduction at once. It is intended.

In addition, the above-mentioned antistatic sheet is provided on a carpet laid in a room, a chair mat for operation of a computer, a floor mat laid at a doorway of a room, an entrance mat, and an opening / closing door in an elevator or an elevator hall. When used as a floor mat to be laid, or a mat to be laid in the interior of automobiles, trains, and airplanes, carpets, and wall materials, microorganisms will propagate along with the occurrence of mites in a place kept at temperature and humidity. However, the sheet is easily discolored and an offensive odor is generated, and the sheet tends to be unsanitary. In addition, there is a problem that the original static electricity removing effect of the antistatic sheet is hindered by the propagation of microorganisms.

Under these circumstances, attempts have been made to impart antibacterial properties to antistatic sheets that remove static electricity. As means for imparting antibacterial properties to the sheet, Shokai Kai 6
As shown in No. 0-171440, there is a method in which an antibacterial acrylic synthetic fiber or a fiber containing an antibacterial agent such as a halogenated bisphenol is used as a constituent fiber of the sheet. or,
As disclosed in JP-A-60-234633, there is also a method of applying a resin containing an antibacterial and antifungal agent onto the surface of the constituent fibers of the pile yarn that is driven into the sheet.

However, when such a means for imparting antibacterial property is applied to an antistatic sheet for removing static electricity, the sheet can be provided with antibacterial property, but the surface of the sheet is covered with a resin or antibacterial fiber. Therefore, there is a problem that the static elimination effect for removing static electricity of the sheet is reduced or disappears. Further, as in the case of covering the sheet surface with a resin, in order to obtain one antibacterial antistatic fiber sheet, the process of imparting antibacterial property and the process of imparting a static elimination effect must be performed separately. As a result, the antibacterial antistatic fiber sheet has become very expensive.

Another object of the present invention is to combine the excellent static elimination effect and insect repellent effect, and to prevent damage due to static electricity and generation of mites,
In addition to being able to solve the obstacles due to breeding all at once,
Provided with antibacterial and insect-proof sheet that has excellent antibacterial properties, prevents discoloration and offensive odor of the sheet due to the growth of microorganisms, and prevents the static elimination effect of the antistatic sheet from being hindered by the growth of microorganisms. It is to be.

In particular, moon peach and silkworm banana, which have been conventionally known as insect repellent trees, have components having excellent insect repellent, fungicidal and fungicidal effects on leaves and stems. Moreover, even though peaches and lindens, cypresses and cedars, also known as insect repellent trees, require decades to return to their original environment once they are felled, they cannot be easily transplanted. In comparison, since it can be transplanted in a strain and easily propagates, there is no fear that its use will lead to the destruction of the global environment. This natural insect repellent material is contained in the sheet either alone or in a mixture of two or more species.

Further, this natural insect repellent material contains an insecticide. As the insecticide, those having a repellent effect or an insecticidal effect against harmful insects such as mites, blemishes, fleas, and ants, especially mites, are difficult to dissolve in water, and do not easily expire upon contact with air are desirable. For example, phosphorus-based and pyrethroid-based insecticides (acaricides) that have been widely used from the past, JP-A-61-1
No. 22205, an insecticide (miticide) containing iodinated formal as a main component, JP-A-61-91103.

Anything is fine. This is because in the case of using a heating means as in the case of a binder-adhesive type or a heat-adhesive type non-woven fabric, the insecticide may be affected by the heat and may be ineffective. The basis weight of the non-woven fabric is preferably one having a strength and an elongation such that it is not easily damaged during handling or driving of pile yarns, and preferably 100 to 200 g / m ² .

The woven or knitted fabric can be produced by bundling a plurality of the above-mentioned natural insect repellent materials and / or conductive fibers into a yarn, and weaving or knitting the yarn into warp yarns and / or weft yarns. In addition, in order to improve the strength of the woven or knitted fabric, the natural insect repellent material and / or the conductive fiber are mixed with other fibers, and the obtained yarn is woven or knitted into warp and / or weft. You can also

When the natural insect repellent material is a powder, it is applied to a sheet by coating it with an adhesive or by dispersing it in a dispersion medium, and impregnating the sheet in this dispersion liquid to attach it to the sheet and include it. be able to. In particular,
When the sheet is a non-woven fabric or a knitted material, the natural insect repellent material and the adhesive will enter the inside of the sheet by coating or impregnation, which is preferable in that the natural insect repellent material and the adhesive do not easily fall off from the sheet.

When the natural insect repellent is an extract, or when the natural insect repellent is an extract contained in a microcapsule having an outer wall made of a microporous film, this is applied or impregnated onto a sheet together with an adhesive. By doing so, it can be attached to and included in the sheet. In particular, when the sheet is a non-woven fabric or a knitted material, the natural insect repellent material and the adhesive will enter the inside of the sheet by coating or impregnation, which is preferable in that the natural insect repellent material and the adhesive do not easily fall off from the sheet.

The content of the natural insect repellent material and the conductive fiber in the sheet is not particularly limited and is optional. However, if the content of these is too large, the strength of the sheet decreases and the cost becomes high. The amount of the material and the conductive fiber to be blended may be appropriately determined in consideration of the application and usage form.
