    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.

    Hazards of electromagnetic radiation:

    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, and hinder hormones, 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.

    Electromagnetic radiation protective 100% silver fiber knitted hat

    (Specific composition of outer fabric: 100% cotton; inner fabric: 100% silver fiber)

    Frequency range: 9KHz-40GHz

    Shielding effectiveness: 45.0dB-68.6dB

    Silver fabric analysis:

    Radiation-proof fabric made of silver-containing fiber using nanotechnology is the latest radiation-proof technology in the world after metal anti-radiation fiber cloth. It has the functions of radiation protection, anti-bacterial and
    anti-fouling. It’s anti-radiation effect is superior to radiation-proof fabric made of other metal materials.
    The silver fiber fabric is highly conductive and has an electromagnetic shielding function. When people wear
    anti-electromagnetic wave knitted hat to contact an electronic device, the anti-electromagnetic wave knitted hat can quickly and effectively conduct electromagnetic waves, thereby protecting the head from electromagnetic waves.

    Silver fiber fabric recommended use environment: Radar stations, electronic countermeasure, wireless communication base stations, civil aviation, meteorology, high-speed, intelligent building monitoring rooms, electromagnetic compatibility laboratory, 5G communication, new energy vehicles, railway communication maintenance, etc.

    The maintenance method of silver fiber:

    Silver fiber 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. if don’t use, it’s recommended sealed.

    1. It’s recommended to wash with well water, mineral water, pure water; (Reason: Some tap water contains chloride ion, too much chloride ions are prone to chemical reactions with silver ions)

    2. Neutral detergent short time soaking; (Don’t use acidic detergent or laundry detergent)

    3. Can’t rub and washing machine wash, can’t be bleached, after knitted hat 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. Wash as little as possible to avoid improper washing affecting the shielding effect.

    [NOTE]: Cell phone signal doesn’t equal cell phone radiation

    My anti-radiation knitted hats are protected against electromagnetic waves generated by the sudden increase or decay of electric currents in electronic components, and aren’t anti-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:

    Electromagnetic radiation will interfere with the normal operation of audio equipment, causing the audio equipment to emit “si si” noise. After the audio equipment is completely covered with electromagnetic radiation protective clothing, the “si si” noise will weaken or disappear.

    3.Conductivity test method:

    The difference between radiation protection fabrics and ordinary fabrics is that radiation protection fabrics are conductive, while ordinary fabrics are non-conductive. use a multimeter to test whether the fabric has resistance(resistance proves that the fabric is conductive), you can know whether the fabric has radiation protection.

    4.Professional radiation equipment test method:

    The first step: Use the electromagnetic radiation detector to detect the radiation of the computer screen, and the corresponding radiation value will be displayed.

    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 host, the radiation value will decrease or become zero.
