Problems solved by technology

[0002] Electromagnetic radiation is a phenomenon in which electromagnetic waves generated by the interaction of electric and magnetic fields are emitted or leaked into the air. With the advancement and development of science and technology, various electrons continue to enter our lives, which not only brings convenience, but also causes a lot of problems. Electromagnetic radiation pollution, long-term exposure to electromagnetic pollution will bring hidden dangers to people's health
[0003] In the existing technology, we have developed a large number of fabrics with electromagnetic shielding performance for anti-electromagnetic radiation pollution, but the electromagnetic shielding performance cannot meet our needs, which brings inconvenience to practical applications
