It is known that clothing has a loose fit, but these clothes are not flexible and do not feel comfortable when worn. It was bad. In addition, knitted fabrics using metal-plated fibers and knitted fabrics directly plated are The clothes used are relatively flexible and comfortable to wear. However, if you use this directly on the outer layer, When worn, the metal layer may fall off due to friction etc. when worn, reducing electromagnetic shielding properties. Ru. In addition, these electromagnetic shielding clothes have electromagnetic shielding properties on the outer material. In many cases, a certain cloth is used, and only a monotonous color pattern and uniform appearance can be obtained, making it difficult to decorate. It had poor performance and low electrical resistance, so there was a risk of electricity passing through it. Also, high frequency electromagnetic Waterproofing is required when working outdoors in waves or in a workplace exposed to water. electromagnetic There are fabrics with wave shielding properties laminated with vinyl chloride, polyethylene, etc. However, since it is not moisture permeable, it has the disadvantage that it gets stuffy while being worn.
