Electrical appliances that use electricity generate electromagnetic waves. The electromagnetic wave is a kind of energy wave having a wide frequency range generated in the flow of electricity and magnetism.

Electromagnetic waves are electromagnetic energy with a wide range of frequencies, from direct current with a frequency of 0 kHz to gamma rays with a frequency of 1022 kHz, and travel at a rate of 300,000 km per second, like the speed of light. The frequency represents the number of cycles per second and uses 로는 as the unit.

Carbon fiber uses cellulose, acrylic fiber, vinylon, pitch, etc. as a raw material. The carbon fiber has a change in molecular arrangement and crystals depending on the raw material or processing temperature.

In general, the molecular arrangement of carbon fibers is a structure in which hexagonal rings of carbon are successively formed layered lattice. Carbon fibers are metallic glossy and black or grey. Carbon fiber has the strength of 10 ~ 20g / d, specific gravity 1.5∼2.1, and has excellent heat resistance and impact resistance, resistant to chemicals and high resistance to pests.

Carbon fiber has more than 90% of far-infrared emissivity, and when it meets water molecules, it absorbs and resonates to convert wavelength energy into thermal energy, thereby maximizing the thermal effect. The carbon fiber is to promote the metabolism of humans, such as to maintain an environmentally friendly state without consuming oxygen during heating.

All light is electromagnetic waves, and the wavelength of light determines its properties. In general, the shorter the wavelength is harmful to the human body. Infrared rays, which are invisible light, have wavelengths longer than red in the spectrum of sunlight.
