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.
The influence of electromagnetic radiation on human health:
Electromagnetic wave radiation has been listed by WHO as the fourth largest source of environmental pollution after water, atmosphere and noise. It has become an invisible “killer” that harms human health. Electromagnetic radiation can generate a lot of free radicals, interfere with communication between cells, hinder hormones and the release of (such as melatonin). Causes cancer, leukemia, cardiovascular and cerebrovascular diseases, miscarriage, menstrual disorders, sexual decline, insomnia and neurological disorders. People who work, study, and live in a concentrated environment of radiation sources are prone to insomnia and dreams, memory loss, physical weakness, and low immunity. The growth rate of cancer cells is 24 times faster than that of normal people. The Swiss standard requires safety within 2mGs outside the 2m range of appliances. The human body can only withstand 2mGs radiation, but it is said that all kinds of household appliances: mobile phone 200mGs, computer 20 ~ 40mGs, copier 40mGs, microwave oven 200mGs, hair dryer 100mGs, TV 20 ~ 40mGs, refrigerator 20 ~ 40mGs. Studies have shown that long-term effects of electromagnetic radiation above 2mGs can cause illness in humans.
The products we sell:
Electromagnetic radiation protective 100% silver fiber knitted fabric(Fixed width of fabric: 1.5m)
Shielding effectiveness: 50.40dB-67.9dB
Shielding principle of 100% silver fiber knitted fabric:
The ring-shaped shielding network composed of silver fibers can generate induced current, which in turn generates a reverse electromagnetic field to shield radiation.
Silver fiber anti electromagnetic radiation fabric exhibits excellent shielding performance in high-frequency electromagnetic radiation environments. The higher the shielding effectiveness value at a certain frequency point or frequency band, the better the protection effect, usually reaching 30dB (equivalent to a shielding rate of 99.9%).
Application scope of 100% silver fiber knitted fabric:
100% silver fiber knitted fabric recommended for use in various military radar stations, electronic countermeasures, wireless communication base stations, civil aviation, meteorology, public security, highways, intelligent building monitoring rooms, electromagnetic compatibility laboratories, 5G communication, new energy vehicles, railway communication maintenance, etc.(Knitted silver fiber anti electromagnetic radiation fabric is relatively soft, has good breathability, and elasticity. It can be directly made into clothes, usually underwear or maternity anti radiation skirts, and can also be used to make window screens.)
Tip: When making clothes with silver fiber knitted fabric, attention should be paid to the front and back of the fabric, and the side that fits the body should be the back of the fabric
How to clean the 100% silver fiber knitted fabric?
100% silver fiber knitted fabric exposed to the air can’t avoid oxidation, the fabric will be black or yellow, is a normal phenomenon, doesn’t affect the shielding effect. It is recommended to seal and store it when not in use.
1. It is recommended to wash with well water, mineral water, pure water; (Reason: Some tap water contains chloride ion, and if the chloride ion is excessive, it is easy to react with silver to reduce the damage to silver by alkali and chlorine)
2. Modest amount of neutral detergent, washing for a short time; (Don’t use acidic detergent or laundry detergent)
3. Can’t rub and washing machine wash. Can’t be bleached, after washed, can’t wring it, pick up directly from the water and hang it in a ventilated and dry room, avoid exposure, don’t recommend ironing;
4. It is recommended to wash it as little as possible prevent improper washing from affecting the shielding effect.
[NOTE]: Cell phone signal doesn’t equal cell phone radiation
The electromagnetic radiation protective fabric is designed to protect against electromagnetic waves caused by the sudden increase or decay of electric currents in electronic components, and they do not shield against cell phone signals.
Fabric test methods:
1.Fabric combustion method:
The residue after the cloth is fully burned is network metal, These metal meshes are used to shield electromagnetic radiation, so it can be proved that the cloth can effectively shield electromagnetic radiation.(This method is only suitable for metal fiber fabric)
2.Speaker noise interference method:
Turn on the audio equipment, the mobile phone next to the audio equipment, so that another person to call the phone, this time you can usually hear the sound of “si si” noise. The reason is that when the mobile phone calls will emit electromagnetic radiation to interfere with the normal operation of the audio equipment, and then cover the audio equipment with a protective clothing completely, then dial this mobile phone, the sound of “si si” voice to eliminate or weaken. This test can prove radiation protection clothing to the shielding effect.
3.Conductivity test method:
electromagnetic radiation protective fabrics and ordinary fabrics are essentially different. electromagnetic radiation protective fabrics are electrically conductive. When the multimeter probes touch the test fabric and the distance between the multimeter probes is 10cm, The multimeter shows a resistance value greater than 0, indicating that the fabric has conductivity and anti-radiation effect.
4.Professional radiation equipment test method:
The first step: Use an electromagnetic radiation detector to detect the radiation value of the computer screen;
The second step: Completely cover the computer screen with electromagnetic radiation protective clothing and then use an electromagnetic radiation detector to detect the radiation of the computer screen, the radiation value will decrease or become 0.
