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. 4, 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 surface of the paper. 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.
