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.

Why do you need an electromagnetic radiation protective knitted hat?

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. The nervous system is very sensitive to the effects of electromagnetic radiation. After repeated effects of low intensity, the function of the central nervous system changes, and neurasthenia syndrome occurs. It mainly has headache, dizzine, weakne, memory lo, sleep disorders (insomnia, dreams or Drowsine), dozing off during the day, irritability, sweating, palpitations, chest tightne, hair lo, etc., especially difficulty in falling asleep, weakne, hyperhidrosis and memory lo are more prominent, all of which indicate that the brain is dominant in the inhibition proce, so the victim In addition to the above syndromes, there is also a short-term memory lo, the visual motor response time is prolonged; the hand-brain coordination movement is poor, the performance slows down the digital recording, and there are more errors.

Swi standard requirements:

The Swi 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 illne in humans.

Applicable to the crowd:

Electromagnetic radiation protective knitted hat is suitable for people who work long hours or live in areas with large electromagnetic waves. such as computer, printer, radar contact, and wirele testing personnel as well as radio, telecommunications, communications, computer room, laboratory workers, etc. Electromagnetic radiation protective knitted hat can protect against computer radiation, WIFI radiation, monitoring and radiation, protection against the radiation of the base station, radiation of the laboratory and other kinds of radiation. It is the ideal protective products for the army, ing, communications, electricity, schools, media, scientific research and other industries.

The products we sell:

Electromagnetic radiation protective knitted hat

The main radiation protection component of knitted hat:

100% Sier fiber

Frequency range and shielding effectivene:

Frequency range: 9KHz-40GHz

Shielding effectivene: 45.0dB-68.6dB

Anti-electromagnetic wave knitted hat shielding princle:

The fabric used in the radiation protection knitted hat contains a dense metal mesh(The metal is highly conductive and has an electromagnetic shielding function). The metal mesh forms a safety ldquoshield coverrdquo on the whole body, which can effectively block the electromagnetic wave radiation generated by the electrical appliances. When a people wears an 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.

Sier fiber fabric analysis:

The sier fiber radiation protection knitted hats are high-tech product oained by permanently bonding sier to a fiber surface through a special technique. This structure not only makes the sier fiber maintain the textile property, but also gives it all the The magical function of sier, the magical effect of sier fiber. Sier has the most effective antimicrobial properties. Sier fiber radiation-proof fabric made of sier-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, and is the production of radiation-proof knitted hat ideal fabric. Its anti-radiation effect is superior to radiation-proof fabric made of other metal materials, which can be worn close to the body and beneficial to the human body.

How to clean the radiation protective knitted hat?

Sier 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. To reduce the oxidation of washing, it is recommended to keep the head and face clean when using, if don't use, it is recommended sealed.

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 exceive, it is easy to react with sier to reduce the damage to sier 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 washing, you can't wring it, pick up directly from the water and hang it in a ventilated and dry room, avoid exposure;

4. It is recommended to wash or wash as little as poible to prevent improper washing effect of shielding.

[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 harmle 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 radiation protection knitted hats can't be based on the strength of mobile phone signals.

My anti-radiation knitted hats 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:

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 equment, the phone next to the audio equment, 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 phone calls will emit electromagnetic radiation to interfere with the normal operation of the audio equment, and then cover the speaker with a protective clothing completely, then dial this 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:

Radiation protection fabrics and ordinary fabrics are eentially different. Since metal fiber and sier fiber can conduct electricity, radiation protection fabrics are electrically conductive, while ordinary fabrics aren't electrically conductive. When the multimeter pen is in contact with the test fabric and the distance is 10cm, The multimeter shows the resistance value, indicating that the fabric has conductivity, so it has anti-radiation effect.

4.Profeional radiation equment 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.
