が指摘されている。2. Description of the Related Art In recent years, with the development and development of electronic devices, there has been an increasing need to shield these devices from the influence of surrounding electromagnetic waves.
There is also a problem that an electromagnetic wave generated from the electronic device itself exerts a disturbance on the outside. For example, adverse effects on the human body due to electromagnetic waves generated from home electric appliances such as microwave ovens and electronic communication devices such as mobile phones are gradually revealed, and countermeasures are required. In the case of a microwave oven or other device placed in contact with a wall in the room, electromagnetic waves from the back of the device often leak to the next room, and are buried in the human body by using mobile phones in cars or medical facilities. It has been pointed out that a malfunction may occur in a heart pacemaker, medical equipment, or the like, which has been used.

する保護手段を身につけていなければならない。[0003] However, the effect of leakage of electromagnetic waves in a room varies depending on the layout and the arrangement of furniture and the like. Therefore, it is necessary to individually take measures against electromagnetic wave shielding in accordance with the place where the source is located. Further, since the source of electromagnetic waves from a cellular phone or the like used in a car cannot be specified at all, the wearer of a pacemaker, for example, must always wear protective means against them for safety.

It is desirable that part of the article or interior article itself be provided with effective electromagnetic shielding means.

から人体を確実に保護することを考えた。[0005] The present inventors have reported that natural leather, which is generally used as a material for bags and shoes, has recently been used as a material for interiors such as wall hangings and clothing such as jackets because of its luxurious texture and durability. In the course of research to develop new uses by giving products made of such natural leather materials more diverse appearances, these products were subjected to electromagnetic wave shielding. The idea is to protect the human body from the harmful effects of electromagnetic waves in the living environment by combining the effects of the magnetic field.

ことは困難である。As a general countermeasure against electromagnetic wave shielding, an electromagnetic wave from a source is reflected or absorbed on the surface of the object to be protected and charges are discharged to the ground. As a means for this, the surface of the object is electrodeposited. Or by applying a metal thin film or by applying a thin metal film, or for example, in the case of textile products, a metal or carbon material is used as a part of the fiber, or in the case of a molded product, a conductive agent is blended as a part of the material, and the material itself is used. To make it conductive (Japanese Patent Publication No. 6-324231).
And JP-A-6-257044). But,
Here, it is difficult to apply these means in the case of natural leather in which an electromagnetic shielding effect is to be imparted, in view of the properties of the material.

実験および研究をつづけた結果本発明を完成した。The present inventor has paid attention to forming a surface coating on a natural leather by applying a printing technique and the like which has not been considered so far, thereby applying a desired pattern and coloring to the leather surface. Focusing on obtaining an electromagnetic shielding effect by giving the medium used for printing etc. conductivity while making it a material with a new feeling,
As a result of continuing experiments and studies, the present invention was completed.

The problem is solved by a natural leather product having an electromagnetic wave shielding effect, characterized in that it is applied as a mesh pattern by screen printing with a thickness of 0 to 40 μm and an electromagnetic wave shielding film is formed on the surface.

われ電磁波シールト効果が得られなくなる。[0010] Natural leather is a porous and highly flexible material having a fine pore structure. Therefore, ordinary printing inks and the like do not always provide sufficient printability. Cracks or partial shedding may occur. In such a case, the conductivity of the entire coating film is lost, and the shielding function cannot be obtained. For example, if an acrylic ink or the like of a normal temperature drying type is used in consideration of the fact that the printing target is a natural leather material, fine cracks are generated in the coating film, the whole conductivity is lost, and the electromagnetic wave shielding effect cannot be obtained.

There is a risk of disconnection.
On the other hand, when the thickness is too large, the printing process itself becomes difficult, and when a noble metal conductive agent is used, the material cost increases. The preferred thickness is about 20-40 μm. The conductive ink film thus formed imparts practically sufficient electromagnetic shielding properties to articles as described later.

でも特に適している。Since the material of the natural leather product used in the present invention has high flexibility as described above and has irregularities on the surface, it is difficult to perform the printing itself by letterpress printing or the like, but a so-called screen printing technique is applied. As a result, a uniform and defect-free printed film can be formed on the surface of the object. Natural leather has irregularities on the surface due to its porous structure, but screen printing can form a relatively thick film while filling these irregularities with ink supplied from the screen gap, which may cause film breakage. Less is. Compared with letterpress printing, etc., screen printing is performed in a small lot and at a low speed in a sheet-by-sheet format. However, when printing is performed using a natural leather material as a control as in the present invention, it is an appropriate printing method. . When the article is a garment such as a leather jacket, the screen printing is particularly suitable in this respect, since it is preferable to apply the printing film as a mesh pattern instead of a so-called solid in order to maintain the original breathability of the leather material.

減衰傾向が示されるものと考えられる。The result of measuring the degree of attenuation (-dB) of the case where the shield was not placed on the wall mounted with the electromagnetic wave shielding film in an electric field having a frequency in the range of 0 to 1000 MHz was compared with the case without the shielding film. As shown in FIG. As shown in FIG. 1, the electric field intensity is attenuated by about −20 to −30 dB from a frequency of about 200 MHz, and particularly, 700 MHz.
In the frequency band of z to 1000 MHz, attenuation of 30 to 40 dB was observed. It is considered that almost the same attenuation tendency is exhibited in a higher frequency range.

This shield effect is expressed in decibels (dB). The greater the dB value, the more effective the shielding effect. The following is a standard for expressing the electromagnetic shielding effect by specific numerical values. 0 to 10 dB: almost no shielding effect 10 to 30 dB: minimum shielding effect 30 to 60 dB: sufficient shielding effect for practical use 60 to 90 dB: excellent shielding effect 90 dB or more: extremely excellent shielding effect effect

れる。It is generally said that there is no practical problem if a shielding effect of 30 to 40 dB is provided. Therefore, in the present invention, since the electric field intensity is attenuated by 30 dB or more in the frequency band of 700 MHz or more, this wall-mounted electromagnetic wave shielding effect is practically sufficient for electromagnetic waves generated from a microwave oven or the like. It is thought that it is.

FIG. 2 shows the results when printing was performed using a 55-mesh screen. Also in this case, the wall hanging with natural leather shows almost the same electromagnetic wave shielding effect as in the case of FIG. 1, and the same effect can be obtained in the case of a printed film using a 300-mesh screen (not shown). Was.
Although the thickness of the film formed by screen printing changes depending on the mesh, the results of the above experiments confirmed that the electromagnetic wave shielding effect hardly changed depending on the thickness.

考えられる。The present invention can be applied to various natural leather products in addition to the wall-hung described in the above embodiment. For example, the electromagnetic wave shielding effect can be applied to all or main parts of outerwear such as leather jackets or the like. The ink coating may be formed by screen printing and solid printing to provide protective clothing for pacemaker users. Thus, when the mobile phone is used near the user of the pacemaker, the possibility that the pacemaker stops or malfunctions due to the electromagnetic wave can be prevented. In this case, since the range of the operating frequency of the mobile phone is specified, the range of the frequency spectrum of the generated electromagnetic wave can be almost predicted. Therefore, it is considered that it is possible to perform printing in a pattern in which the distance between the fine lines of the electromagnetic wave shielding film gives the most effective shield for the wavelength of the target electromagnetic wave.
