What is electromagnetic radiation?

Electromagnetic radiation is "non-ionizing radiation," including microwaves and electromagnetic fields (EMF). Any type of electrical appliance produces non-ionizing radiation, including cell phones, computers, televisions, wires, and ultrasound.

This is electromagnetic radiation protective soft metal fiber fabric

Frequency range and shielding effectiveness:

Frequency range: 30MHz-18GHz   

Shielding effectiveness: 12.2dB-49.4dB

Fabric analysis:

The metal fiber has been in the market for a long time. The product technology is mature. The Copper, nickel fiber with ion precision quenching technology is blended with other fibers. good air permeability and good radiation protection effect.

Metal fiber fabric shielding principle:

The fabric contains a dense metal mesh. The metal mesh forms a safety ldquoshield coverrdquo, which can effectively block the electromagnetic wave radiation generated by the electrical appliances and Avoid radiation damage to the human body.

Recommended use environment: Metal fiber fabric is recommended for daily office, high-speed rail, small monitoring room, power plant, substation and so on.

[NOTE]:

The thickness of the metal fiber fabric is similar to that of the common work clothes fabric, and it can be used to make clothes directly. 

The maintenance method of metal fiber:

1. Hand wash, can be brushed with soft brush, avoid rubbing and machine washing;

2. After washing, you can't wring it, remove it directly from the water, and keep it cool;

3. Don‘t irons;

4. It is recommended not wash as much as possible in case of improper washing.

[NOTE]: Cell phone signal does not equal cell phone radiation

The mobile phone signal is a high-frequency microwave signal. It is the ability of the mobile phone itself to receive signals. It is basically harmless to the human body. The mobile phone signal has spread all over the world and is also supported by the countries of the world. The mobile phone can automatically search for signals. The steel in high-rise buildings is all steel. The elevator can receive signals, so the mobile phone initiative to search for signals has its own particularity. The protective effect of metal fiber fabrics can't be based on the strength of mobile phone signals.

My anti-radiation metal fiber fabrics are protected against electromagnetic waves generated by the sudden increase or decay of electric currents in electronic components, and are not anti-cell-phone signals.

Fabric test methods:

1.Fabric combustion method:

(1)Metal fiber

Ignite the attached fabric sample and find that the burnt sample is a very clean and fine network metal, which indicates that the fabric is very good in material and can effectively shield the radiation.

(2)Silver fiber

The attached fabric sample is ignited and burned to a black globule after being completely burned with fire. After being crushed by force, it can be turned into a powder, which indicates that the material of the fabric is very good and can effectively shield the radiation.

2.Conductivity test method:

Radiation protection clothing and ordinary clothing fabrics are essentially different. Since metal fiber and silver fiber can conduct electricity, radiation protection suits are electrically conductive, while ordinary clothes are not electrically conductive. Bring your own multimeter, or take the radiation protection suit to the appliance maintenance department to check the conductivity of the radiation protection suit.

(1)Ordinary clothing detection

The multimeter is adjusted to the 200 Omega or 2K Omega position. When the multimeter pen is in contact with the test fabric and the distance is 10cm, the resistance value is 1 and the value of the multimeter when the object is not tested is 1, indicating that the ordinary fabric is non-conductive.

(2)Metal fiber testing

The multimeter is adjusted to the 2k Omega gear position. When the multimeter pen is in contact with the test fabric and the distance is 10cm, the resistance value fluctuates around 0.421K Omega, indicating that the metal fiber radiation protection suit has conductivity, so it has anti-radiation effect.

(3)50% Silver fiber testing

The multimeter is adjusted to the 200 Omega gear position. When the multimeter pen touches the test fabric and the distance is l0cm, the measured resistance value fluctuates around 1.1 Omega, indicating that the conductivity of the 50% silver fiber radiation protection suit not only is better than that of the metal fiber but also the radiation protection effect also better than metal fiber.

(4)100% Silver fiber testing

The multimeter is adjusted to the 200 Omega position. When the multimeter pen is in contact with the test fabric and the distance is 10cm, the measured resistance value fluctuates around 0.4 Omega, indicating that the conductivity of the 100% silver fiber radiation suit is better than that of the 50% silver fiber fabric. The anti-radiation effect is also better. It can be seen from the test that the resistance value of 100% silver fiber is relatively small in the fabric, so the conductivity and anti-radiation effect of 100% silver fiber are also better.

3.Conductive test:

The essential difference between radiation-resistant fabrics and ordinary fabrics is that radiation-proof fabrics are conductive and ordinary fabrics are non-conductive, so test the radiation resistance with a multimeter to see if it is effective.(If there is no multimeter at home, you can take the clothes to the appliance repair department, let the maintenance master test).

4.Professional radiation equipment test method:

The first step: using radiation equipment to detect the host, radiation equipment will display the corresponding radiation value.

The second step: use radiation suits to block the back of the chassis, in the middle of the radiation equipment and the rear of the host computer to block a layer of radiation protection suits, then see the display on the instrument value is 0, indicating that the host computer's electromagnetic radiation is radiated Clothing shielded.
