종래 방탄복으로는 제조하는 종래 기술로는 불소계 수지등을 포함하는 발수제 용액 내에 아라미드 직물을 디핑(Dipping) 시킨 다음, 패딩 및 건조하는 방법으로 발수처리된 아라미드 직물 10~50매를 적층시킨 구조의 방탄복이 널리 사용되어 왔다.Conventional body armor is a conventional technique for manufacturing a body armor of 10 to 50 sheets of water-repellent aramid fabric is laminated by dipping the aramid fabric in a water repellent solution containing a fluorine resin, etc., and then padded and dried. This has been widely used.
그러나, 상기의 종래 방탄복은 아라미드 직물의 발수처리가 약하기 때문에 건조상태의 방탄성능은 우수하지만 습윤상태에서의 방탄성능이 저하되는 문제점이 있었다.However, the above-described conventional body armor has a problem in that the ballistic performance in the dry state is excellent but the ballistic performance in the wet state is deteriorated because the water repellent treatment of the aramid fabric is weak.
아울러, 상기의 종래 방탄복은 방탄성능 시험시 방탄복의 후면변형이 NIJ(National Institute of Justice) 기준인 44㎜이하를 겨우 만족하는 수준으로서, 보다 엄격한 후면변형 기준이 요구되는 경우에는 적용에 한계가 있는 문제점도 있었다.In addition, the above-described conventional body armor is a level at which the rear deformation of the body armor only satisfies 44 mm or less of the NIJ (National Institute of Justice) standards when the ballistic performance test, and there is a limit to the application when more stringent rear deformation standards are required. There was a problem.
이와 같은 종래의 문제점들을 해결할 수 있도록 본 발명에서는 습윤상태에서의 방탄성능이 우수하고, 방탄성능 시험시 방탄복의 후면변형이 NIJ 규격 기준보다 월등하게 우수한 방탄용 직물 및 방탄복을 제공하고자 한다.In order to solve the above problems, the present invention is to provide a bulletproof fabric excellent in bulletproof performance in the wet state, and excellent anti-ballistic fabric and body armor in the rear deformation of the body armor when the anti-ballistic performance test superior to the NIJ standard.
이와 같은 과제들을 달성하기 위해서, 본 발명에서는 방탄용 직물의 발수처리를 2차에 걸쳐 실시하여 방탄용 직물상에 2층의 발수층, 다시 말해 1차 발수코팅층(20)과 2차 발수코팅층(30)을 차례로 형성시킴으로써, 이로 제조된 방탄복의 습윤상태시 방탄성능을 향상시킨다.In order to achieve the above problems, in the present invention, the water-repellent treatment of the anti-ballistic fabric is carried out over two times, so that the water-repellent layer of two layers on the anti-ballistic fabric, that is, the primary water repellent coating layer 20 and the second water repellent coating layer 30) are formed in turn, thereby improving the ballistic performance in the wet state of the body armor thus prepared.
또한, 본 발명에서는 고탄성 아라미드 직물(A)내에 수지가 함침되어 있는 제1의 아라미드 프리프레그(X)와 고탄성 아라미드 직물(B) 내에 수지가 함침되어 있는 제2의 아라미드 프리프레그(Y)가 열압착되어 일체로 적층된 구조인 아라미드 복합 패드(40)를 방탄복 일부에 형성된 주머니 내에 삽입하여 방탄성능시 방탄복의 후면변형을 크게 감소시킨다.In the present invention, the first aramid prepreg (X) in which the resin is impregnated in the high elastic aramid fabric (A) and the second aramid prepreg (Y) in which the resin is impregnated in the high elastic aramid fabric (B) are heated. The aramid composite pad 40, which is compressed and integrally stacked, is inserted into a pocket formed in a part of the body armor, thereby greatly reducing the rear deformation of the body armor during ballistic performance.
본 발명은 발수성능이 뛰어나 습윤상태에서의 방탄성능이 크게 향상되고, 특히 아라미드 복합 패드(40)가 삽입된 방탄복의 경우에는 방탄성능시험 후 방탄복의 후면변형이 크게 감소한다.The present invention has excellent water repellency, and greatly improves anti-ballistic performance in a wet state. Especially, in the case of the body armor having the aramid composite pad 40 inserted therein, the rear deformation of the body armor after the anti-ballistic performance test is greatly reduced.

다음으로는, 맹글(Mangle)을 사용하여 전방향족 폴리아미드 직물내에 함침된 발수제 조성물 중 일부, 다시 말해 60%의 픽업율(Pick-up rate)로 제거한 다음, 계속해서 150℃의 텐더(Tenter) 내에서 1분 동안 건조하여 방탄용 직물을 제조하였다.Next, some of the water repellent compositions impregnated into the wholly aromatic polyamide fabric, using a Mangle, i.e. at a pick-up rate of 60%, were then removed, followed by a tender at 150 ° C. It was dried for 1 minute to produce a bulletproof fabric.
다음으로는, 상기와 같이 제조된 방탄용 직물 40매를 적층하여 방탄복을 제조하였다.Next, bulletproof clothing was prepared by laminating 40 bulletproof fabrics prepared as described above.
이와 같이 제조한 방탄복의 물성을 평가한 결과는 표 1과 같았다.The results of evaluating the physical properties of the body armor thus prepared were shown in Table 1.

준비된 각 아라미드 복합체를 물에 30분간 침지후 꺼낸 직후 NIJ(National Institute of Justice) 규격 3A등급 기준으로 44 매그넘(44 mag)을 사용하여 방탄성능을 측정하였다. 한편, 44 매그넘의 총알 스피드인 436m/초를 기준으로 허용 기준 범위내에서 V0을 측정하여 방탄성능을 평가하였다.The prepared aramid complex was immersed in water for 30 minutes, and immediately after being taken out, bulletproof performance was measured using 44 magnums (44 mag) based on the National Institute of Justice (NIJ) standard 3A grade. On the other hand, the bulletproof performance was evaluated by measuring V0 within the allowable reference range based on the 436m / sec bullet speed of 44 Magnum.
본 발명은 발수성능이 뛰어나 습윤상태에서의 방탄성능이 크게 향상되고, 특히 아라미드 복합 패드(40)가 방탄복에 형성된 주머니 내에 삽입된 경우 방탄성능 시험 후 방탄복의 후면 변형이 크게 감소하기 때문에 방탄복으로 유용하다.The present invention is excellent in water repellency, and greatly improves the anti-ballistic performance in the wet state, and especially when the aramid composite pad 40 is inserted into a pocket formed in the body armor, it is useful as a body armor because the rear deformation of the body armor after the anti-ballistic performance test is greatly reduced. Do.
