Surface resistance measurement method
Measurement conditions
- 1. Sample size：100mm×100mm
- 2. Electrode (Grip)10mm×100mm（Sample contact part）
- 3. tester：HIOKI製 3220mΩ HITESTER
- 4. The sample is clamped so that both ends are 100 mm apart.
- 5. The resistance values of the sample in the warp and weft directions are read.
As a result of the above, the surface resistance is 1.4 Ω in the vertical direction and 3.3 Ω in the horizontal direction, making it highly conductive and a material suitable for preventing static electricity.
Regarding cold protection
Human body thermograph measurement conditions
The test was carried out under the following conditions:
- 1. Room temperature 25 degrees Celsius. Environmental chamber temperature 10 degrees Celsius.
- 2. Wear a multi-purpose vest under a cotton dress shirt
- 3. A comparison of human thermographs with and without the multi-vest after 10 minutes at 10 degrees Celsius
As a result, it is clear that the body surface temperature is higher when wearing the multi-vest. This is due to the radiant heat and heat storage effect of the silver fiber. When the silver fiber is worn on the outermost layer, heat is dissipated and the body actually feels cooler.

Antibacterial properties
An antibacterial test of MGnet was conducted by the Japan Chemical Fiber Inspection Association. Antibacterial effects were observed against Staphylococcus aureus, Klebsiella pneumoniae, MRSA, Escherichia coli, and Pseudomonas aeruginosa. Similar performance was confirmed in tests after 50 washes. (Example data: Staphylococcus aureus, viable cell count 20 or less, bacteriostatic activity value 5.8 or more, bactericidal activity value 3.1 or more) In addition, food was covered with MGnet, and the results of Escherichia coli culture after leaving it for 24 hours were compared between when a sanitary sheet from another company was used and when nothing was done. The results are as follows, demonstrating the high antibacterial properties of MGnet.
About ICNIRP High Frequency Electromagnetic Wave Guidelines
The ICNIRP (International Commission on Non-Ionizing Radiation Protection) guidelines restrict high-frequency electromagnetic waves from 10MHz to 10GHz using SAR (specific absorption rate, defined as the absorbed power per kilogram of body weight = Wkg-1). The limit values are 0.4Wkg-1 for the whole-body average SAR, 10Wkg-1 for the local SAR in the head and trunk (the torso and testicles are particularly affected), and 20Wkg-1 for the local SAR in the limbs (hands and feet). There are many communication devices such as wireless LAN in office environments and daily life. The device that generates the strongest high-frequency electromagnetic waves is the mobile phone, but this falls below the ICNIR guidelines, and it is currently considered that there is no risk of health damage. The IARC (International Agency for Research on Cancer), which was mentioned in the IH Anshin Apron low-frequency electromagnetic wave protection measurement results, has not yet listed the carcinogenicity of low-power high-frequency electromagnetic waves. We believe that low-frequency electromagnetic waves (low-frequency magnetic fields) have a greater impact on the body than high-frequency electromagnetic waves. We believe that static electricity and cold air from air conditioners have a greater impact on the body than weak high-frequency electromagnetic waves from office work and daily life, and so we developed the "Fairy Veil" and "Multi Vest" that provide protection against high-frequency electromagnetic waves, static electricity, cold air, and bacteria. If you are concerned about your health, we recommend that you try them out. Please understand that none of the conventional office work electromagnetic wave countermeasure products, including our "Fairy Veil" and "Multi Vest," are effective against low-frequency magnetic fields.
