Today, homes are using various home appliances developed for the convenience of life, and the use of home appliances is increasing day by day. These home appliances are driven by using electric energy. Most products that use electric energy generate a certain amount of electromagnetic noise. This noise is a form of electromagnetic radiation through the air or conduction through wires such as power lines. Is delivered to. Therefore, unless you return to primitive life, you can not avoid completely from electromagnetic waves, and you will always be exposed to electromagnetic waves.

In particular, with the development of information and communication technology, devices that use radio waves, such as various portable communication devices, TVs, radios, and radios, are increasing, and many electromagnetic waves have been transmitted to power lines for supplying power to homes, buildings, and factories. They are exposed to many kinds of electromagnetic waves, such as causing damages to humans and electronic devices of nearby residents.

As described above, the effects of electromagnetic waves emitted from various home appliances, computer devices, and transmission lines on the human body range from the human brain to the heart, and the effects of the electromagnetic interferences may include the strength of the noise source, the transmission path, the distance from the noise source, the coupling structure, Extremely low frequency and low frequency of the electromagnetic wave are generated by electric field and magnetic field, and when the human body is exposed for a long time, the body temperature change and biological rhythm are broken and it is likely to develop into a disease. The harmful effects of electromagnetic waves are being revealed one after another by the World Health Organization's investigation, and even electrically operated various electronic products, industrial facilities, airplanes, and medical devices are malfunctioned by harmful electromagnetic waves, causing large accidents. In addition to the problems that can be caused by In the laboratory, there was a problem that the reliability of the research and experimental results may be lowered by the electromagnetic exposure.

On the other hand, various curtains are used for the purpose of controlling the rays, blocking the line of sight, soundproofing, soundproofing, and cold protection in the windows and entrances of various buildings. As a method of installation, it was used to attach a loop to a crease and to hang it on a fixed pipe or wire, but recently, a simple rail was developed, and a pulley was attached to the loop to open and close lightly. Vertical blinds have been developed, and roll blinds are used for shading or interior decoration, and roll blinds can be conveniently adjusted by winding the shields to the top.

However, these types of curtains were not used as a means to block electromagnetic waves mainly because they mainly aimed at shades, insulation, and insulation.

The present invention has been devised in view of the above circumstances, and using an aluminum strip coated with a PET strip on one side as a string and a blade, and weaving it in a lattice shape, weaving it so that electrical conduction occurs at the contact area where the aluminum strip intersects. Using the electromagnetic wave shield, it is possible to make the shading fabric of the louver or roll blind of vertical blind and install it on the window sill where electromagnetic waves can flow from each building to block the inflow or outflow of electromagnetic waves, and also have an insulation effect. The purpose of the present invention is to provide an electromagnetic wave blocking blind that can secure breathability and transparency by adjusting the weaving density of the light blocking fabric.
