Abstract

본 발명은 천연 혹은 합성섬유 직물의 경, 위사에 전기 도체인 금속사를 적당한 간격으로 삽입하여 금속사가 직물내에 바둑판 모양으로 함입된 직물에 관한 것으로서 외부에서 오는 전자파(마이크로 전자파)가 직물내의 금속사에 흡수토록 하여 직물 내측의 신체에 전자파가 침투하는 것을 방지할수 있도록 한 직물에 관한 것이다. 실 예로 일반 면직물에 금속사를 7-8mm 정도 간격의 바둑판 모양 으로 삽입하여 만든 직물로 휴대전화를 감쌓을 경우 휴대전화의 전자파를 흡수차단 하여 휴대전화의 발신과 수신이 되지 않는다. 이러한 직물로 옷을 만들어 입을경우 휴대전화등 각종 유해 전자파의 피해로부터 신체를 보호할수 있게 한다. 도1은 평직 직물의 조직도로서 금속사(1)를 임의 일정한 간격으로 경, 위사의 면사(2) 사이에 삽입하여 바둑판 모양으로 금속사가 삽입된 본 발명의 직물에 관한 것이다.The present invention relates to a fabric in which the metal yarn, which is an electrical conductor, is inserted into the light and weft yarn of a natural or synthetic fiber at appropriate intervals, and the metal yarn is embedded in a checkerboard pattern. The present invention relates to a fabric that can be absorbed in to prevent penetration of electromagnetic waves into the body inside the fabric. For example, when wrapping a mobile phone with a fabric made by inserting a metal thread into a regular cotton fabric in the form of a checkerboard with a gap of about 7-8 mm, the mobile phone absorbs electromagnetic waves and does not transmit or receive the mobile phone. If you make clothes with these fabrics, you can protect your body from the damage of various harmful electromagnetic waves such as mobile phones. Figure 1 is a structure of the plain weave fabric relates to the fabric of the present invention in which the metal yarn 1 is inserted into the checker board shape by inserting the metal yarn 1 between the warp, weft yarn 2 at any regular interval.

Description

금속사를 삽입한 전자파 흡수직물{omitted}Electromagnetic wave absorbing fabric with metal yarn

도1은 본 발명의 평직 직물 조직도1 is a plain weave fabric organization of the present invention

도2는 본 발명의 금속사가 삽입된 직물의 사시도.Figure 2 is a perspective view of a fabric in which the metal thread of the present invention is inserted.

본 발명은 휴대전화 등과 같이 전자파를 발생시키는 전자 전기 기기에서 발생하는 전자파를 흡수할수 있도록 금속사를 삽입한 직물로서 전자파가 인체에 침투하는 것을 방지하여 전자파로부터 인체를 보호하도록 만든 직물에 관한 것이다. 종래에는 프라스틱 혹은 일반 직물등 물체의 표면에 금속을 증착도금 혹은 도포하여 전자파를 반사 시키는 등의 방법으로 전자파의 침투를 방지 하였으나 본 발명은 일반 직물의 제직시 경사, 위사 사이에 필요에 따른 임의 간격으로 금속사를 삽입 제직하여 만든 직물로서 전자파의 흡수기능이 있는 직물에 관한 발명인 것이다.The present invention relates to a fabric made by inserting a metal yarn to absorb electromagnetic waves generated by an electronic and electrical device generating electromagnetic waves, such as a mobile phone, to protect the human body from electromagnetic waves by preventing electromagnetic waves from penetrating the human body. Conventionally, the penetration of electromagnetic waves was prevented by depositing or coating metal on the surface of an object such as plastic or general fabric to reflect electromagnetic waves. However, the present invention provides a random spacing between the warp and weft yarns when necessary. The invention relates to a fabric having a function of absorbing electromagnetic waves as a fabric made by inserting a woven metal yarn.

본 발명의 금속사를 삽입한 전자파 흡수직물을 면직물에 적용할 경우의 예를 들어 제직할 경우 경사빔을 만들 때 일반 면 경사 사이에 임의 정한 간격으로 금속사를 삽입 정경하여 경사빔을 만들어 사용하고 위사에는 경사의 경우와 같거나 비슷한 간격으로 금속사를 타입하여 제직 생상하는 직물로서 금속사가 바둑판 모양으로 삽입되어 구성된 직물인 것이다. 도1에서 금속사(1)는 면사(2)사이에 임의 정한 간격으로 바둑판 모양으로 삽입된다. 실제 제직시 금속사의 경우 실의 신도가 일반 면사나 합섬사와 달라 제직시의 경사 장력 조정의 편의상 경사빔을 일반사와 별도로 만들어 이중빔을 사용하여 제직함이 효율적이다.In the case of applying the electromagnetic wave absorbing fabric in which the metal yarn of the present invention is inserted into a cotton fabric, for example, when weaving the warp beam, the warp beam is formed by inserting the metal yarn at regular intervals between the inclined planes. The weft yarn is a woven fabric produced by weaving metal yarns at intervals the same as or similar to that of warp yarns. In FIG. 1, the metal yarn 1 is inserted in a checkerboard shape at a predetermined interval between the cotton yarns 2. In actual weaving, in the case of metal yarns, the elongation of the yarn is different from that of ordinary cotton yarns or synthetic yarns.

이상에서 설명한 바와 같이 본 발명의 금속사를 삽입한 전자파 흡수직물은 휴대전화 등 에서 발생하는 전자파를 흡수 차단하는 기능이 있는 직물로서 본발명의 직물(도2)로 옷을 만들어 입을경우 외부에서 오는 전자파를 흡수 차단하여 인체를 전자파로부터 보호하게 한다.As described above, the electromagnetic wave absorbing fabric into which the metal yarn of the present invention is inserted is a fabric having a function of absorbing and blocking electromagnetic waves generated from a mobile phone. Absorb and block electromagnetic waves to protect the human body from electromagnetic waves.

실제 7-8mm의 간격으로 경, 위사에 금속사를 삽입한 직물로 휴대전화를 감싼후 동 휴대전화에 전화를 걸면 전파가 감싼 직물에 흡수 차단되어 통화가 연결되지 않으며 감싼 전화에서 타 전화로 발신하는 것도 전화에서 발산되는 전파가 동 직물에 흡수차단 되어 통화연결이 되지 않는다.Wrap a mobile phone with a fabric with a metal thread inserted in the weft yarn at an interval of 7-8mm, and when you make a phone call, the radio wave is absorbed by the wrapped fabric and the call is not connected. In addition, the radio waves emitted from the phone are blocked by the fabric and thus cannot be connected.
