도면중, A는 본 발명 직물, 1은 합섬필라멘트사, 2는 금속증착필름사, 3은 합섬필라멘트사와 금속증착 필름사와의 합연사.In the figure, A is a fabric of the present invention, 1 is a filament filament yarn, 2 is a metal vapor deposition film yarn, 3 is a joint yarn of the filament filament yarn and metal deposition film yarn.

본 발명은 레이더전파와 같은 극초단파감시 체제로부터 목표물을 위장시키는데 사용되는 직물에 관한 것이다.The present invention relates to fabrics used to camouflage targets from microwave surveillance systems such as radar waves.

본 발명은 경량이면서 유연성이 풍부한 극초단파 산란용 직물을 저렴한 가격으로 제공하며 또 국내에서 구득이 용이한 원료를 사용하여 특수한 제조장치를 요함이 없이 매우 용이하게 제조할 수 있는 극초단파 산란용 직물을 제공하는데 그 목적이 있는 것이다.The present invention provides a microwave and fabric for microwave scattering, which is lightweight and flexible, at a low price and can be manufactured very easily without requiring a special manufacturing apparatus using raw materials easily obtained in Korea. The purpose is.

오늘날 전자장비의 고도화로 말미암아 물표물을 레이더와 같은 극초단파 감시체제로부터 위장시킬 필요성이 더욱 증대되고 있으며 때문에 실용성이며 저렴한 가격의 극초단파 산란용 직물의 제공이 시대적으로 절실하게 요청되고 있는 실정이다.Today, due to the advancement of electronic equipment, the necessity of disguising a target from a microwave surveillance system such as a radar is increasing. Therefore, there is an urgent demand for providing a practical and low-cost microwave scattering fabric.

그러나 종래의 극초단파 산란용 포지들은 다음과 같은 문제점들이 있었다.However, the conventional microwave scattering forge had the following problems.

이 중에서 부직포를 기재로 한 것은, 섬유웰의 표면에 전도성금속의 세편들이나 전도성금속의 단섬유를 살포하여 고척시킨 것인데 이것은 부직포를 기재로 한 것이므로 인장강도, 인열강도 등의 물리적 내구성이 불량하고 아울러 일정한 형태를 유지시켜 주는 형태안정성이 부족하여서 실용성이 부족하였다.Among them, the nonwoven fabric is based on the surface of the fiber well by sprinkling pieces of conductive metal or short fibers of the conductive metal. The nonwoven fabric is based on the nonwoven fabric and thus has poor physical durability such as tensile strength and tear strength. In addition, there is a lack of practicality because of the lack of form stability that maintains a certain form.

또 특허공고 81-1207호로 알려진 편직위장물은 합성섬유 단섬유와 스테인리즈강 섬유와 같은 금속전도성 섬유를 혼방하여 방적한 혼방사를 원사로 사용하여서 망으로 제편하고 그 양면을 유연성필름으로 피복 접착시킨 것이었는 바 이것은 강도나 형태안정성 면에서는 우수한 반면에 다음과 같은 결점이 수반되어서 우리 나라에서는 제품화시키는데 난점이 있다.In addition, the knitted fabric known as Patent Publication No. 81-1207 is made of a mixture of short fibers of synthetic fibers and metal conductive fibers such as stainless steel fibers, which are spun into yarn using yarn spun as a yarn, and coated on both sides with a flexible film. While it is excellent in strength and form stability, it is difficult to commercialize in our country due to the following drawbacks.

즉, 상기의 것은 0.008~0.02mm 굵기의 스테인리즈강 섬유를 주원료로 사용하는 것이므로 원료 구입이 용이하지 않을뿐 아니라 이와 같은 금속섬유를 합성섬유와 혼방하여야 하기 때문에 특수한 방적설비를 요하여야만 하는 설비면의 제약이 뒤따르고, 또 스테인리즈와 같은 금속섬유는 합성섬유와의 포합성이 약하기 때문에 고도의 방적기술을 필요로 하여서 결과적으로 제품의 가격이 매우 높아지는 단점을 면할 수 없다. 또 상기의 것은 강도보강과 유연성을 부여하기 위한 라미네이팅 공정을 거쳐야 하므로 제조공정이 매우 복잡하였다.That is, since the above is to use the stainless steel fiber of 0.008 ~ 0.02mm thickness as the main raw material, it is not easy to purchase the raw materials, and the surface of the facility that requires special spinning equipment because such a metal fiber should be mixed with synthetic fiber. In addition, since metal fibers such as stainless steel are poorly combined with synthetic fibers, high spinning technology is required, and as a result, the price of the product is very high. In addition, since the above must undergo a laminating process to give strength reinforcement and flexibility, the manufacturing process is very complicated.

본 발명자는 상술한 바와 같은 선행기술의 제반 문제점을 장기간에 걸쳐서 예의 검토한 결과 전도성 금속편이나 전도성 금속섬유를 사용하는 대신에 전도성금속의 증착필름사를 사용하더라도 직물에 동등하게 극초단파산란효과를 부여할 수 있는 점에 착안하여 본 발명을 완성하였다.The present inventors have diligently studied all the problems of the prior art as described above, and as a result, even when using a deposited metal yarn of a conductive metal instead of using a conductive metal piece or a conductive metal fiber, it is possible to impart an ultra-short scattering effect to a fabric. The present invention has been completed by focusing on the possible points.

본 발명에서 사용되는 전도성 금속의 증착필름사는 합성수지필름 표면에 전도성 금속을 증착시킨 것을 소폭으로 절단시킨 것을 말하며 여기에서 전도성금속이라고 함은 알루미늄, 동, 납, 니켈 등이며, 이중에서 알루미늄이 경량이고 가격이 저렴하므로 유리하다. 합성수지필름은 폴리에스텔필름, 폴리에스틸렌필름 등을 들을 수 있으나 제직성이나 기타 물성등을 고려할때 폴리에스텔필름이 가장 적합하다. 전도성금속의 증착필름사는 유연성과 인장강도 등을 고려할때 두께는 20~35미크론, 폭은 0.5mm~0.7의 것이 가장 적합하다.Deposition film of the conductive metal used in the present invention refers to a small cut of the deposition of the conductive metal on the surface of the synthetic resin film, wherein the conductive metal is aluminum, copper, lead, nickel, etc., among which aluminum is lightweight and It is advantageous because the price is low. Synthetic resin film may include polyester film, polyester film, etc., but polyester film is most suitable in consideration of weaving properties and other physical properties. Deposition film of conductive metal is most suitable for thickness of 20 ~ 35 micron and width of 0.5mm ~ 0.7 in consideration of flexibility and tensile strength.

본 발명의 극초단파산란용 직물(A)은 경.위사에 95~210대니어의 폴리아마이드필라멘트사나 폴리에스텔필라멘트사(F)를 사용하고 전도성 금속의 증착필름사(M)는 각각 경사 또는 위사방향으로 그 간격이 3~9m/m가 되게 배치시켜서 전도성금속의 증착필름사(M)로 둘러쌓인 단위면적이 25~81m/m2이 되도록 하였다.The microwave microwave fabric (A) of the present invention uses 95-210 Danier polyamide filament yarn or polyester filament yarn (F) for light and weft yarns, and the deposited film yarn (M) of the conductive metal is inclined or weft directions, respectively. The spacing was arranged to be 3 ~ 9m / m so that the unit area surrounded by the deposition film yarn (M) of the conductive metal is 25 ~ 81m / m 2 .

본 발명에서 전도성 금속의 증착필름사(M)가 경.위사 방향에서 그 간격이 9m/m가 초과되면 레이더 전파의 감쇄량이 급격히 감소되어서 충분한 위장효과를 발휘할 수 없으며 3m/m보다 적게하면 자체 반사율이 증가하여 바람직하지 못하였으며, 직물의 믈성면에서 인장강도, 파열강도 및 마찰강도 등이 현저히 저하되므로 실용성이 없었다.In the present invention, when the deposition film yarn M of the conductive metal exceeds 9 m / m in the light and weft direction, the attenuation amount of the radar radio waves is rapidly reduced, so that the camouflage effect cannot be sufficiently exhibited. This increase was not preferable, and since the tensile strength, the bursting strength, the frictional strength, etc. in the fabric properties of the fabric were significantly reduced, it was not practical.

본 발명에서의 전도성 금속의 증착필름사(M)는 제2(a)도의 단면도시에 도시된 것을 그대로 사용할 수도 있으며 경우에 따라서는 제2도(b)도에서 예시한 바와 같이 합성섬유필라멘트사(F)와 합연한 합연사(T)의 형태로 사용할 수도 있다.Deposition film yarn (M) of the conductive metal in the present invention may be used as it is shown in the cross-sectional view of Figure 2 (a) and in some cases synthetic fiber filament yarn as illustrated in Figure 2 (b) It can also be used in the form of a twisted yarn (T) combined with (F).

본 발명 직물(A)을 사용함에 있어서는 육안감시나 적외선 또는 자외선 감시로부터도 위장하기 위하여 직물표면에 이와 같은 성능의 특수한 코팅제를 도포시킬 수 있으며, 또 방화성 화합물이나 방매성 화합물 등을 코팅제에 혼합하여 도포할 수도 있다.In the use of the fabric (A) of the present invention, a special coating agent having such a performance can be applied to the surface of the fabric in order to camouflage it from the naked eye or infrared or ultraviolet ray monitoring. You may apply it.

아울러 레이더 전파의 산란효과를 더욱 효과적으로 증대시키기 위하여 본 발명 직물(A)을 제3도와 같이 펀칭한 것을 트와인 네트(Twine net)에 부착하여 사용하는 것이 좋다.In addition, in order to more effectively increase the scattering effect of the radar propagation, it is preferable to use the punched fabric of the present invention (A) attached to a twine net (Twine net).

본 발명은 전도성 섬유를 종래처럼 고가이고 구득이 어려운 금속세편이나 금속섬유 또는 금속세선 대신에 전도성금속증착필름사를 사용하되 그 간격을 적절하게 배역시킴으로서 중량이 가볍고 유연성이 풍부하며 실용성 있는 극초단파 산란용 위장직물을 얻을 수 있다.The present invention uses conductive metal deposition film yarns instead of metal pieces, metal fibers or metal wires, which are expensive and difficult to obtain, as conventionally, but by weighting the gaps properly, they are light in weight, have abundant flexibility, and are practical for microwave scattering. You can get a camouflage fabric.
