전자파 차폐용 원단{FABRICS FOR SHIELDING AN ELECTROMAGNETIC WAVE}{FABRICS FOR SHIELDING AN ELECTROMAGNETIC WAVE}

본 발명은 전자파 차폐용 원단에 관한 것으로, 보다 상세하게 전도성이 있는 금속망을 원단내에 삽입하거나 또는 섬유로 된 원사에 대해 동선을 위사 또는 경사로 직조하여 전자파를 차폐할 수 있는 의류나 모자, 신발, 휴대폰케이스, 쇼파, 방석, 카펫, 숄 등을 제작할 수 있는 전자파 차폐용 원단에 관한 것이다.The present invention relates to a fabric for shielding electromagnetic waves, and more particularly, to a fabric for shielding electromagnetic waves by inserting a conductive metal mesh into a fabric or by woven a copper wire with a weft or weave to fabricate a textile, A cellular phone case, a sofa, a cushion, a carpet, and a shawl.

주지된 바와 같이, 전자 및 통신산업의 고도화와 더불어 전자기기 및 전기제품의 발달이 가속화되고 있다. 반면 이러한 전자기기 및 전기제품 이용의 가속화와 함께 필연적으로 나타나는 전자파의 위해와 전자파 환경(EMC)의 오염이라는 새로운 문제점을 야기시키고 있어 신체 및 각종 기기의 위해 및 오작동, 교란 등 악영향을 미치는 전자파를 차폐하고자 많은 노력을 기울이고 있다.As is well known, along with the advancement of the electronic and communication industries, the development of electronic devices and electric products is accelerating. On the other hand, due to the acceleration of the use of electronic devices and electric appliances, it causes new problems such as the harmful electromagnetic waves and the contamination of the electromagnetic environment (EMC), thereby shielding the electromagnetic waves which adversely affect the harmful and malfunction of the body and various devices, We are making a lot of effort to do this.

이러한 전자파로 인한 위해를 최소화하기 위하여 여러 가지 방법이 제안되고 있으나 실용화된 것은 거의 없으며 상용화되더라도 그 효과는 미미한 실정이다. 일반적으로 전자파를 막기 위한 방법으로 동판을 사용하거나 알루미늄 박지를 사용하고 있으나 컴퓨터 및 각종 통신장비 등의 전기, 전자제품에서 발생하는 전자파를 완전하게 차폐하기는 어려우며 그러한 방법 또한 제품이 고가이거나 부피가 커지고 효율면에서 떨어지는 등의 문제점을 내포하고 있다.Although various methods have been proposed to minimize the harm caused by such electromagnetic waves, there have been few commercialized methods, and even if they are commercialized, their effect is negligible. Generally, a copper plate or an aluminum foil is used as a method for blocking electromagnetic waves. However, it is difficult to completely shield electromagnetic waves generated from electric and electronic products such as computers and various communication equipments. Such methods are also expensive and bulky And the efficiency is deteriorated.

특히, 최근에는 스마트폰을 포함한 각종 태블릿 전자기기들을 휴대하는 관계로 인해 유저는 깨어있는 대부분의 시간을 휴대용 전자기기와 함께 보내는 바, 전자파의 경우 호접속을 시도하는 경우나 또는 데이터통신을 위한 접속을 시도하는 시점에 더 많은 양이 방사되게 되므로 빈번하게 무선 인터넷 통신을 수행하는 청소년들이 더 많은 빈도로 전자파에 노출되어져 있다고 할 수 있다.Particularly, recently, due to the portable portable electronic devices including the smart phone, the user sends most of the awake time together with the portable electronic device. In the case of the electromagnetic wave, when the user tries to make a call connection, It is possible that more youth are frequently exposed to electromagnetic waves as they are frequently engaged in wireless Internet communication.

그렇다보니, 이제 전자파 차폐는 데스크탑이나 TV, 냉장고 등의 고정된 전자기기를 작동시킬 때에 국한하여 필요한 것이 아니고, 모든 일상 생활에서 필요한 환경이 되어 버렸다. 하지만, 주로 금속판으로 이루어진 전자파 차폐수단으로 사용하여 일상 생활속에서 전자파를 차폐하기란 현실적으로 어려움이 많았다.As a result, electromagnetic shielding is not necessary only when operating fixed electronic devices such as desktops, TVs, and refrigerators, and has become an environment necessary for all daily life. However, it was difficult to shield electromagnetic waves in everyday life by using electromagnetic wave shielding means mainly made of metal plate.

본 발명은 상기한 종래 기술의 사정을 감안하여 이루어진 것으로, 전도성이 있는 금속망을 원단내에 삽입하거나 또는 섬유로 된 원사에 대해 동선을 위사 또는 경사로 직조하여 전자파를 차폐할 수 있는 의류나 모자, 신발, 휴대폰케이스, 쇼파, 방석, 카펫, 숄 등을 제작할 수 있는 전자파 차폐용 원단을 제공함에 그 목적이 있다. SUMMARY OF THE INVENTION The present invention has been made in view of the circumstances of the prior art described above, and it is an object of the present invention to provide a garment, a hat, and shoes capable of shielding an electromagnetic wave by inserting a conductive metal net into a fabric or woven a copper wire with a weft or weave , A mobile phone case, a sofa, a cushion, a carpet, a shawl, and the like.

상기한 목적을 달성하기 위해, 본 발명의 바람직한 실시예에 따르면 섬유사로 이루어진 상부 원단(6)과 하부 원단(8)의 사이에 그물형상의 금속사로 이루어진 차폐망(4)이 내삽되어 재봉됨으로 인해 구성되되, 그 차폐망(4)은 구리, 니켈, 알루미늄과 같은 전도성이 높은 금속망인 것을 특징으로 하는 전자파 차폐용 원단이 제공된다.In order to achieve the above object, according to the preferred embodiment of the present invention, the shielding net 4 made of a net-like metal yarn is inserted and sewn between the upper end fabric 6 and the lower fabric end 8 made of fiber yarns Wherein the shielding net (4) is a metal mesh with high conductivity, such as copper, nickel, aluminum and the like.

바람직하게, 상기 섬유사(12)와 금속사(14)가 각각 교번적으로 직조되거나 또는 상기 섬유사(12)가 위사로 배치되고 금속사(14)는 경사로 배치되거나 또는 상기 섬유사(12)가 경사로 배치되고 상기 금속사(14)는 위사로 배치되거나 또는 상기 섬유사(12)와 금속사(14)가 경사와 위사로 혼합된 혼합 직조된 것을 특징으로 하는 전자파 차폐용 원단이 제공된다. Preferably, the fiber yarn 12 and the metal yarn 14 are alternately woven or the fiber yarns 12 are arranged in a weft and the metal yarns 14 are arranged in an inclined manner, Wherein the metal yarn 14 is arranged in a warp and the metal yarn 14 is arranged in a weft yarn or the fiber yarn 12 and the metal yarn 14 are mixed and knitted in warp and weft yarns.

본 발명에 따른 전자파 차폐용 원단은 원단 내부에 금속망으로 이루어진 차폐망이 구성되므로 각종 의류 및 책상보, 모자, 신발, 휴대폰케이스, 카펫과 같이 생활 곳곳에 사용되는 용품을 전자파 차폐용품으로 제작할 수 있고, 그로인해 전자파를 효과적으로 차폐하여 인체에 미치는 악영향을 제거할 수 있게 하며, 유연한 원단 특성을 그대로 살리면서 차폐가 이루어지도록 할 수 있고, 섬유사와 금속사로 직조 단계에서부터 차폐용 원단으로 제작된 원단은 두께가 얇고 금속망이 밀리는 이물감이 없다는 장점이 있다.Since the electromagnetic wave shielding fabric according to the present invention has a shielding net made of a metal net inside the fabric, it is possible to manufacture an electromagnetic shielding article for various items such as clothes, desk lamps, hats, shoes, cell phone cases and carpets , Thereby effectively shielding electromagnetic waves to eliminate the adverse effects on the human body.

도 1은 본 발명의 일실시예에 따른 전자파 차폐용 원단의 구성을 도시한 측단면도, 도 2는 본 발명의 일실시예에 따른 전자파 차폐용 원단의 구성을 도시한 분해사시도, 도 3은 본 발명의 일실시예에 따른 전자파 차폐용 원단에 포함된 금속망을 도시한 도면, 도 4는 본 발명의 일실시예에 따른 전자파 차폐용 원단을 이용한 차폐 효과를 나타내는 그래프이다.FIG. 1 is a side sectional view showing the configuration of a raw material for electromagnetic wave shielding according to an embodiment of the present invention, FIG. 2 is an exploded perspective view showing the configuration of a raw material for electromagnetic wave shielding according to an embodiment of the present invention, FIG. 4 is a graph illustrating a shielding effect using a fabric for shielding electromagnetic waves according to an embodiment of the present invention; FIG. 4 is a view illustrating a metal net included in a fabric for shielding electromagnetic waves according to an embodiment of the present invention;

이를 참조하면, 본 발명의 일실시예에 따른 전자파 차폐용 원단(2)은 전도성이 있는 금속망을 원단내에 삽입하거나 또는 섬유로 된 원사에 대해 동선을 위사 또는 경사로 직조하여 전자파를 차폐할 수 있는 의류나 모자, 신발, 휴대폰케이스, 쇼파, 방석, 카펫, 숄 등을 제작할 수 있는 원단이다.Referring to FIG. 1, the electromagnetic wave shielding fabric 2 according to an embodiment of the present invention can shield electromagnetic waves by inserting a conductive metal mesh into a fabric or by weaving a copper wire with a weft or weave It is a fabric that can make clothes, hats, shoes, cell phone cases, sofas, cushions, carpets and shawls.

보다 상세하게, 본 발명의 일실시예에 따른 전자파 차폐용 원단(2)은 섬유사로 이루어진 상부 원단(6)과 하부 원단(8)의 사이에 그물형상의 금속사로 이루어진 차폐망(4)이 내삽되어 재봉됨으로 인해 구성되되, 그 차폐망(4)은 구리, 니켈, 알루미늄과 같은 전도성이 높은 금속망으로 이루어진다.More specifically, in the electromagnetic wave shielding raw fabric 2 according to the embodiment of the present invention, a shielding net 4 made of a net-like metal yarn is inserted between the upper fabric 6 made of fiber yarn and the lower fabric 8, And the shielding net 4 is made of a highly conductive metal net such as copper, nickel, or aluminum.

금속사를 직조하여 그물망 형상으로 구성한 차폐망(4)은 그 통공(10)의 직경에 따라 차폐효과에 차이가 있지만, 통공(10)이 조밀할수록 더 높은 차폐 효과를 갖는 것은 당연하다.Although the shielding net 4 formed by weaving metal yarns in a net shape has a shielding effect depending on the diameter of the through hole 10, it is natural that the dense hole 10 has a higher shielding effect.

금속사는 바람직하게, 구리, 니켈, 알루미늄을 기본 재질로 선택할 수 있으며, 황동이나 일반 철재라고 할지라도 전도성은 비철금속이나 비금속보다 높으므로 채용 가능하다. 유연성이나 강도 및 전도성을 모두 고려할 때 동재질이 가장 최적의 재료라고 할 수 있다.The metal wire is preferably made of copper, nickel, or aluminum as a basic material, and even if it is made of brass or general steel, the conductivity is higher than that of non-ferrous metal or nonmetal. Considering both flexibility, strength and conductivity, copper is the most suitable material.

상기 차폐망(4)은 그 통공(10)의 직경이 0.01 내지 0.1㎜이 바람직하며, 50 내지 300 mesh/inch의 형태를 가지고 있으며, 차폐 효과는 200 mesh/inch의 경우 수백 ㎒의 주파수를 80db까지 차단하며, 수 ㎓의 경우 40db까지 전자파를 차단할 수 있다.The diameter of the through-hole 10 of the shielding net 4 is preferably 0.01 to 0.1 mm and is in the range of 50 to 300 mesh / inch. When the shielding effect is 200 mesh / inch, the frequency of several hundred MHz is 80 dB And in case of several GHz, the electromagnetic wave can be blocked up to 40 db.

상기 차폐망(4)의 간격 및 두께에 따른 전자파의 차단효과(SE)를 식으로 나타내면 다음과 같다.The shielding effect SE of the electromagnetic wave according to the interval and the thickness of the shielding net 4 can be expressed as follows.

상기한 식을 고려해볼 때, 상기 차폐망(4)의 통공(10)은 조밀할수록 차폐효과가 크고, 동으로 이루어진 그물망이 차폐효과가 큼을 알 수 있다.Considering the above equation, it can be seen that as the through hole 10 of the shielding net 4 is dense, the shielding effect is large and the net made of copper has a high shielding effect.

또, 본 발명의 다른 실시예에 따른 전자파 차폐용 원단(2’)은 상기 섬유사(12)가 위사로 배치되고 금속사(14)는 경사로 배치하여 직조할 수 있다.In addition, the electromagnetic wave shielding fabric 2 'according to another embodiment of the present invention can be woven by arranging the fiber yarn 12 in a weft and the metal yarn 14 in a warp arrangement.

또한, 본 발명의 다른 실시예에 따른 전자파 차폐용 원단(2’)은 상기 섬유사(12)가 경사로 배치되고 상기 금속사(14)는 위사로 배치하여 직조할 수 있다.In addition, the fabric 2 'for shielding electromagnetic waves according to another embodiment of the present invention may be woven by disposing the fiber yarns 12 in an inclined manner and arranging the metal yarns 14 in a weft.

이러한 구성으로 이루어진 본 발명의 다른 실시예에 따른 전자파 차폐용 원단(2’)은 섬유사(12)와 함께 금속사(14)가 직조된 구성을 가지므로, 제 1실시예의 차폐용 원단(2)과는 다르게 차폐망(4)이 상부원단(6)과 하부원단(8) 사이에서 밀리지 않는다.Since the electromagnetic wave shielding fabric 2 'according to another embodiment of the present invention having such a structure has a structure in which the metal yarn 14 is woven together with the fiber yarn 12, the shielding fabric 2 The shielding net 4 is not pushed between the upper fabric 6 and the lower fabric 8.

한편, 본 발명의 실시예에 따른 전자파 차폐용 원단은 단지 상기한 실시예에 한정되는 것이 아니라 그 기술적 요지를 이탈하지 않는 범위내에서 다양한 변경이 가능하다.
