| Electromagnetic radiation can cause serious damage to the health of human, and electromagnetic waves caused by electromagnetic interference will seriously interfere the accuracy of the electronic equipment and the normal operation. Electromagnetic pollution has also become the fourth-largest pollution after the air pollution, water pollution and noise pollution. How to reduce and avoid the electromagnetic pollution, protect human health, and protect the human living environment has become the focus of problem for the domestic and overseas. At present, the electromagnetic shielding fabric also has many limitations, such as no personal wear, not washing, feel is hard, dull and so on.Firstly, through basic research and explore of electromagnetic wave shielding and the principle electromagnetic wave theory, using wire mesh structure theory, and combining the existing electromagnetic shielding fabric strengths and weaknesses, analyze the main influence factors on electromagnetic radiation fabric performance. Research shows that:(1) The silver fiber is thicker, its fabric shielding performance is higher.(2) The fabric density is bigger, the better electromagnetic shielding effect.(3) The different structure of fabric, form network structure of silver fiber is also not identical. The same of weight, woven fabric shielding performance better than knitted fabric.(4) Test showed that scouring will cause serious damage to the silver fiber, sample basic no shielding effectiveness.For the needs of the market, based on the analysis of the investigation, through careful design of rational choice theory research, fiber raw material and fabric structure, give full play to the shielding effect of silver fiber, developed silver fiber cotton cloth, silver fiber cloth towels and silver fiber health cloth three electromagnetic shielding fabric. The test results show that, this is the three section of the electromagnetic shielding fabric not only has good anti electromagnetic radiation, antistatic, antibacterial property, but also has a thin and soft, breathable and comfortable, rich color etc. The silver fiber health cloth fabric as an example, the silver fiber intermediate formed a unique "S" shaped three-dimensional groove structure, and the double-sided fabric has the characteristic of three layer structure, and can be completely covered in silver fiber yarn. Because of silver fiber can be completely cotton cover, not only to protect the silver fiber, and more colorful, and is not affected by the silver fiber, feels better, to fill the gaps in the field.Fabric development and utilization of these three new electromagnetic shielding maternity, infant wear, children and other products on the market, welcomed by consumers, has been widely recognized by the market. |
