본 고안은 본 고안자의 선출원인 특허공고 제84-586호를 개량한 것이다.The present invention is an improvement on Patent Publication No. 84-586, which is a prior application of the inventor.

상기한 선출원 발명은 합성수지필름의 한쪽면에 전도성 금속을 증착시킨 전도성금속사를 경, 위사 방향으로 보통의 합성섬유사 사이에 3m/m-9m/m의 간격으로 배열시킴으로서 가격이 저렴하고 경량이며 유연성이 풍부한 극초단파산란용 위장직물을 얻을 수 있는 장점이 있었으나, 반면에 상기한 선출원 발명은 한면만이 전도성금속으로 증착된 것을 사용한 것이었기 때문에 금속증착층이 손상되는 경우에 소기의 목적을 달성하기 어려웠으며 또 경, 위사 방향으로 배열된 전도성금속사가 서로 접촉하게되면 만족할만한 산란효과를 발휘할 수 없었던 문제점이 있음을 알게 되었다.The above-described invention is a low cost and light weight by arranging conductive metal yarns in which conductive metals are deposited on one side of a synthetic resin film at intervals of 3 m / m-9 m / m between ordinary synthetic fiber yarns in a light and weft direction. While there was an advantage of obtaining a flexible microwave scattering camouflage fabric, on the other hand, the above-described prior invention uses only one surface deposited with a conductive metal, thus achieving the desired purpose when the metal deposition layer is damaged. It was difficult and also found that when the conductive metal yarns arranged in the light, weft direction contact each other, there was a problem that could not exhibit a satisfactory scattering effect.

또한 상기한 선출원발명은 전도성금속증착층이 한면에만 형성된 것이므로 전도성금속층의 안정성을 위하여 상대적으로 두께를 두껍게 하고 전파를 받는 면적을 크게하지 않을 수 없었다.In addition, the above-described invention of the present invention, because the conductive metal deposition layer is formed only on one side, for the stability of the conductive metal layer is relatively thick and forced to increase the area to receive radio waves.

그 때문에 전도성 금속사의 두께와 폭이 직물원사의 것보다 커지므로 직물의 표면이 고르지 못하게 되어 이후의 코팅작업시에 많은 문제점을 유발하였었다. 본 고안은 상술한 문제점을 해결한 것으로서 이하 상세히 설명하면 다음과 같다.Therefore, since the thickness and width of the conductive metal yarn is larger than that of the woven yarn, the surface of the fabric is uneven, which causes many problems in subsequent coating operations. The present invention solves the above problems and will be described in detail below.

본 고안에서 사용하는 전도성금속사는 제1a도에 도시한 바와같이 합성수지 필름베이스(1)의 표리면에 전도성금속을 증착시켜서 전도성 금속증착층(2)(2')을 형성시킨 다음 다시 이것의 표리면을 얇은 합성수지필름으로 라미네이팅 하거나 합성수지로 도포하여 합성수지피막층(3)(3')을 형성시킨 세폭의 전도성 금속증착필름사(M)로 되어 있다.The conductive metal yarn used in the present invention is formed by depositing the conductive metal on the front and back surfaces of the synthetic resin film base 1 as shown in FIG. 1A to form the conductive metal deposition layers 2 and 2 ', and then again the table thereof. It is made of a narrow conductive metal deposition film yarn (M) in which the back surface is laminated with a thin synthetic resin film or coated with a synthetic resin to form a synthetic resin film layer (3) (3 ').

본 고안에서의 전도성금속사는 제2b도에서 예시한 바와 같이 합성섬유필라멘트사(F)와 합연한 합연사(T)의 형태로 사용할 수도 있다.The conductive metal yarn in the present invention may be used in the form of a twisted yarn (T) bonded with synthetic fiber filament yarn (F) as illustrated in FIG. 2b.

여기에서 전도성금속은 알루미늄, 동, 니켈 등이며 이중에서 알루미늄이 경량이고 가격이 저렴하므로 유리하다.Here, the conductive metal is aluminum, copper, nickel, and the like, of which aluminum is advantageous because it is lightweight and inexpensive.

합성수지필름은 폴리에스테르필름, 폴리아마이드필름 등을 들 수 있으나 제직성이나 기타 물성등을 고려할 때 몰리에스텔필름이 가장 적합하다.Synthetic resin film may include polyester film, polyamide film, etc., but in view of weaving or other physical properties, the most suitable is a polyester film.

전도성금속필름사(M)는 제직성, 직물의 강도와 내구성 및 평활한 직물표면의 제공이라는 점을 고려하여 두께는 12미크론-35미크론, 폭은 0.3m/m-0.7m/m로 하는 것이 좋다.The conductive metal film yarn (M) has a thickness of 12 microns-35 microns and a width of 0.3 m / m-0.7 m / m in consideration of the weaving property, the strength and durability of the fabric, and the provision of the smooth fabric surface. good.

본 고안은 경, 위사에 70-210 데니어의 폴리아마이드 필라멘트사나 폴리에스테르 필라멘트사(F)를 사용하고 전도성금속증착필름사(M) 혹은 합연사(T)를 경사 또는 위사 방향으로 그 간격이 3-9mm가 되게 제직하여 이것으로 둘러싸인 면적이 9㎟-81㎟가 되도록 하였다.The present invention uses 70-210 denier polyamide filament yarn or polyester filament yarn (F) for light and weft yarns, and the gap between the conductive metal deposition film yarn (M) or twisted yarn (T) in the direction of warp or weft is 3 Weaving was made to be -9mm so that the area surrounded by it was 9mm-281mm2.

전도성 금속사의 간격에 따른 극초단파의 산란효과는 표1과 표2와 같다.The scattering effect of microwaves according to the spacing of conductive metal yarns is shown in Table 1 and Table 2.

본 고안에서 전도성금속사가 표1와 같이 경, 위사 방향에 그 간격이 9mm가 초과되면 감쇄율이 저하되고 개별돌변치가 증가하여 충분한 위장효과를 발휘할 수 없으며 3mm보다 더 좁게하면 자체반사율이 증가하고 제직능률면에서 바람직하지 못할 뿐더러 직물의 인장 및 파열강도 등과 같은 물리적 특성이 현저히 저하되므로 바람직하지 못하다.In the present invention, when the conductive metal yarn exceeds 9mm in the direction of warp and weft as shown in Table 1, the attenuation rate decreases and the individual stone displacement increases, so that the camouflage effect can not be exhibited. Not only is it undesirable in terms of cotton, but is also undesirable because physical properties such as tensile and rupture strength of the fabric are significantly lowered.

본 고안 직물을 사용함에 있어서는 육안감시나 적외선 또는 자외선 감시로부터도 위장하기 위하여 직물 표면에 이와같은 성능을 가진 특수한 코팅제를 도포시킬 수 있다.In the use of the fabric of the present invention, it is possible to apply a special coating having such a capability to the surface of the fabric in order to camouflage from visual or infrared or ultraviolet surveillance.

또한 본 고안을 실제 이용함에 있어서는 극초단파의 산란효과를 증대시키기 위하여 본 고안 직물을 펀칭시킨 뒤 트와인 네트(Twine Net)에 부착하여 제3도와 같이 사용하는 것이 좋다.In addition, in the practical use of the present invention, in order to increase the scattering effect of microwaves, it is preferable to punch the fabric of the present invention and attach it to a twine net to use it as shown in FIG.

본 고안은 선출원의 것에 비하여 전도성금속증착층(2)(2')의 박리나 손상이 합성수지피막층(3)(3')으로 보호되기 때문에 지속적인 극초단파 산란효과를 유지할 수 있으며, 또 전도체로서의 역할을 지속적으로 수행할 수 있게되며, 경, 위사의 전기적 접촉을 방지할 수 있으므로 전파산란효과를 증대시킬 수 있다.The present invention is capable of maintaining a continuous microwave scattering effect and acting as a conductor since the peeling or damage of the conductive metal deposition layer (2) (2 ') is protected by the synthetic resin film layer (3) (3') as compared to the previous application. It can be carried out continuously, and the electric wave scattering effect can be increased because it can prevent the electrical contact of light and weft.

아울러 본 고안은 양면에 전도성금속층(2)(2')이 증착되어 있기 때문에 한면의 전도체가 그 기능을 잃더라도 반대측 전도체가 극초단파 산란효과를 계속 수행할 수 있으며 또 이와같은 전도성금속증착층(2)(2')의 안정성과 합성수지 피막층(3)(3')의 보호역할 때문에 선출원의 것에 비하여 전도성금속사의 두께와 폭을 적게할 수 있고 이로 인하여 제직성이 좋으며 강도와 내구성이 보강될 뿐 아니라 직물의 표면을 평활하게 할 수 있는 장점을 가진다.In addition, the present invention, because the conductive metal layer (2) (2 ') is deposited on both sides, even if one side of the conductor loses its function, the opposite side of the conductor can continue to perform microwave scattering effect and such a conductive metal deposition layer (2 (2 ') and the protective role of the synthetic resin film layer (3) (3'), the thickness and width of conductive metal yarns can be reduced compared to those of the previous application, which results in good weaving and reinforced strength and durability. It has the advantage of smoothing the surface of the fabric.

The attenuation rate was -7db and the reflectance was 50%.
