Silver fiber refers to a composite fiber formed by infiltrating nano-silver ions into nylon fiber. It uses i to generate an induced current according to the loop formed by the Riau silver fiber, and the induced current generates a reverse electromagnetic field for shielding. Silver has a good conductor that can reflect electromagnetic waves, that is, when the aperture of the metal mesh is less than 1/4 of the wavelength of the electromagnetic wave (wavelength = speed of light/frequency), the electromagnetic wave cannot pass through the metal mesh, which plays the role of shielding electromagnetic waves.
