Description

방탄복용 직물 및 이로 제조된 방탄복{Woven fabric for bulletproof cloth and bulletproof cloth manufactured by the same}Woven fabric for bulletproof cloth and bulletproof cloth manufactured by the same}

본 발명은 방탄복용 직물 및 이로 제조된 방탄복에 관한 것으로서, 보다 구체적으로는 경사 및 위사가 꼬임이 가해지지 않는 무연(無撚) 상태의 전방향족 폴리아미드 멀티필라멘트로 구성되어 방탄성이 우수한 방탄용 직물 및 이로 제조된 방탄복에 관한 것이다.The present invention relates to a body armor for body armor and body armor made thereof, more specifically for ballistic excellent excellent ballistic resistance composed of a lead-free poly-aromatic polyamide multifilament of the warp and weft is not applied A fabric and a body armor made therefrom.

종래의 방탄복용 직물 및 이로 제조된 방탄복으로는 나일론 직물(방탄복용 직물)을 수십겹씩 적층한 방탄복 또는 나일론 직물과 전방향족 폴리아미드 직물을 교호로 수십겹씩 적층한 방탄복이 널리 사용되어 왔으나, 방탄성능이 낮아 원하는 방탄성능을 얻기 위해서는 보다 많은 매수의 방탄복용 직물들을 적층해야 함으로 상기 방탄복의 중량이 너무 높아져 착용이 불편한 문제가 있었다.As a conventional body armor fabric and a body armor made thereof, a body armor layer of several layers of nylon fabrics (body armor) or a body armor layer of alternating layers of nylon fabrics and all-aromatic polyamide fabrics has been widely used. In order to achieve the desired anti-ballistic performance, it is necessary to stack a larger number of body armor fabrics, so the weight of the body armor is too high, which causes inconvenience in wearing.

또 다른 종래 기술로는 방탄성능 향상을 위해서 나일론 직물의 적층체 또는 나일론 직물-전방향족 폴리아미드 직물의 적층체에 열경화성 수지를 함침 또는 라 미네이팅한 방탄복이 제안되었으나, 상기 방법은 방탄복의 유연성이 크게 저하되어 착용감이 나쁜 문제가 있었다.In another conventional technique, a body armor having impregnated or laminated with a thermosetting resin in a laminate of nylon fabric or a laminate of nylon fabric-to-aromatic polyamide fabric has been proposed for improving the antiballistic performance. There was a problem that a bad fit was badly reduced.

또 다른 종래기술로서 대한민국 등록특허 제10-306918호 및 대한민국 공개특허 제1993-0013671호에서는 직물을 구성하는 경사 및 위사 모두가 꼬임이 가해진, 다시말해 연사(撚絲)된 전방향족 폴리아미드 멀티필라멘트들로 이루어진 방탄복용 직물(이하"방탄용 아라미드 직물"이라고 한다)을 게재하고 있다.As another conventional technique, Korean Patent No. 10-306918 and Korean Patent Publication No. 199-0013671 show that all of the warp and weft yarns constituting the fabric are twisted, that is, twisted wholly aromatic polyamide multifilament. Body armor fabric (hereinafter referred to as "ballistic aramid fabric") is published.

그러나, 상기의 방탄용 아라미드 직물은 경사 및 위사가 연사된 전방향족 폴리아미드 멀티필라멘트로 구성되기 때문에 상기 직물에 총알로 인한 충격이 가해지면 경사 및 위사의 꼬임부분이 약점(Weak point)로 작용하여 방탄성능이 크게 저하되는 문제가 있었다.However, the bullet-proof aramid fabric is composed of a wholly aromatic polyamide multifilament of warp yarns and weft yarns, and when the impact of bullets is applied to the fabrics, the warp and weft yarns act as weak points. There was a problem that bullet-proof performance is greatly reduced.

본 발명은 중량이 가벼워 착용감이 우수하면서도 뛰어난 방탄성을 발현하는 방탄복용 직물 및 이로 제조된 방탄복을 제공하고자 한다.The present invention is to provide a kevlar body fabric and a kevlar suit made therefrom having a light weight and excellent wearing comfort and excellent ballistic resistance.

상기 과제를 달성하기 위해서 본 발명에서는 전방향족 폴리아미드(이하"아라미드"라고 한다) 멀티필라멘트를 경사 및 위사로 사용하여 방탄복용 직물을 제직할 때 인위적으로 꼬임이 가해지지 않은 무연(無撚) 상태의 아라미드 멀티필라멘트를 사용한다.In order to achieve the above object, in the present invention, a lead-free state in which an artificial twist is not applied when weaving a kevlar fabric by using an wholly aromatic polyamide (hereinafter referred to as "aramid") multifilament as a warp yarn and a weft yarn. Use aramid multifilament of.

본 발명에 따른 방탄복용 직물은 경사 및 위사 모두가 전방향족 폴리아미드 멀티필라멘트로 구성되며, 경사 및 위사를 구성하는 상기 전방향족 폴리아미드 멀티필라멘트가 인위적으로 꼬임이 가해지지 않아 꼬임수가 5개이하/m (이하 "무연(無撚) 상태" 라고한다)인 것을 특징으로 하는 한다.Kevlar fabric according to the present invention, both warp and weft yarn is composed of wholly aromatic polyamide multifilament, and the wholly aromatic polyamide multifilament constituting the warp and weft yarn is not artificially twisted, the number of twist is 5 or less / m (hereinafter referred to as " lead free state ").

방탄복용 직물을 구성하는 경사 및 위사에 인위적으로 꼬임을 부여한 경우 총알로 인한 충격이 방탄복용 직물에 가해지면 상기 꼬임 부분은 가해진 충격을 상기 직물의 전체 면적으로 효과적으로 분산시키는 것을 방해하는 약점(Weak point)로 작용하게 되고, 그로인해 방탄성능이 크게 저하된다.If artificial twist is given to the warp and weft yarn constituting the body armor fabric, when the impact from the bullet is applied to the body armor fabric, the twisted portion prevents effectively dispersing the impact impact to the entire area of the fabric. ), And the antiballistic performance is greatly reduced.

본 발명에서는 상기와 같은 현상을 방지하여 방탄성능을 획기적으로 개선하기 위해서, 방탄복용 직물을 구성하는 경사 및 위사를 인위적으로 꼬임이 가해지지 않아 꼬임수가 5개이하/m로서 사실상 무연(無撚)인 아라미드 멀티필라멘트로 구성한다.In the present invention, in order to prevent the above phenomenon and to significantly improve the bulletproof performance, artificial twist is not applied to the warp and weft yarn constituting the body armor fabric, the number of twist is less than 5 / m virtually lead-free (() It consists of phosphorus aramid multifilament.

상기 아라미드 멀티필라멘트의 꼬임수는 3개이하/m, 보다 바람직하기로는 0개/m인 것이 바람직하다.The number of twists of the aramid multifilament is 3 or less / m, more preferably 0 / m is preferred.

그러나, 아라미드 멀티필라멘트에 인위적으로 꼬임을 가하지 않아도 제직등의 공정에서 5개이하/m의 꼬임은 자연발생적으로 발생될 수 있는바, 본 발명에서는 자연발생적으로 발생되는 꼬임수만 갖는 상태까지를 무연상태라고 한다.However, even if artificial twist is not applied to the aramid multifilament 5 or less twisting / m in the process of weaving, such as can occur naturally, in the present invention lead-free state up to the state having only a naturally occurring twist It is called.

상기 아라미드 멀티필라멘트, 즉 전방향족 폴리아미드 멀티필라멘트는 단사섬도가 0.7~1.6 데니어인 아라미드 모노필라멘트 400~1,000개로 구성되는 것이 바 람직하다.The aramid multifilament, that is, the wholly aromatic polyamide multifilament is preferably composed of 400 to 1,000 aramid monofilament having a single yarn fineness of 0.7 ~ 1.6 denier.

또한, 아라미드 멀티필라멘트의 인장강도는 22g/d 이상인 것이 바람직하다.In addition, the tensile strength of the aramid multifilament is preferably 22g / d or more.

그러나, 본 발명에서는 아라미드 모노필라멘트의 단사섬도 및 개수와 아라미드 멀티필라멘트의 인장강도를 특별히 한정하는 것은 아니다.However, in the present invention, the single yarn fineness and number of aramid monofilaments and the tensile strength of the aramid multifilament are not particularly limited.

한편, 본 발명에 따른 방탄복용 직물은 ISO 13934-1의 스트립 방법(Strip method)으로 측정한 인장강도가 5,000~10,000N/5㎝ 이고, 직물조직이 평직 또는 바스켓직인 것이 바람직하고, 경사밀도 및 위사밀도는 각각 5~15본/㎝ 수준인 것이 바람직하다.On the other hand, the kevlar fabric according to the present invention has a tensile strength of 5,000 ~ 10,000N / 5cm measured by the strip method of ISO 13934-1, it is preferable that the fabric structure is plain weave or basket weave, and the inclination density and Weft density is preferably 5 to 15 books / cm level.

그러나, 본 발명에서는 방탄복용 직물의 인장강도, 조직, 경사밀도 및 위사밀도를 특별하게 한정하는 것은 아니다.However, the present invention does not specifically limit the tensile strength, structure, warp density and weft density of the body armor fabric.

본 발명에 따른 방탄용 직물은 앞에서 설명한 무연(無撚)의 아라미드 멀티필라멘트를 경사 및 위사로 사용하여 평직 또는 바스켓직 등의 조직으로 5~15본/㎝ 수준의 경사 및 위사밀도로 제직하여 제조할 수 있다.Bulletproof fabrics according to the present invention is produced by weaving at a warp and weft density of 5 to 15 bone / cm level with a tissue such as plain weave or basket weave using the above-described lead-free aramid multifilament as warp and weft. can do.

한편, 본 발명에 따른 방탄복은 앞에서 설명한 방탄복용 직물, 보다 구체적으로 경사 및 위사 모두가 무연(無撚)인 전방향족 폴리아미드 멀티필라멘트들로 구성된 방탄복용 직물들이 10~50매가 적층되어 방탄성능(V50)이 0.22(Cal) 파편탄(FSP) 기준으로 1,550ft/초 이상인 것을 특징으로 한다.On the other hand, the body armor according to the present invention is the body armor for the body described above, more specifically 10 to 50 sheets of body armor fabric made of all-aromatic polyamide multifilament that is both lead-free and warp yarn (lead-free) is laminated ballistic performance ( V50) is 1,550ft / sec or more based on 0.22 (Cal) fragmentation coal (FSP).

방탄성능(V50)은 0.22(Cal) 파편탄(FSP)를 사용하여 Mil-STD-662 방법에 의해 측정한다.Bulletproof performance (V50) is measured by the Mil-STD-662 method using 0.22 (Cal) fragmentation coal (FSP).

방탄성능(V50)이 1,550ft/초 라고 함은 1,550ft/초의 속도로 0.22(Cal) 파편탄(FSP)을 방탄복에 쏘았을 때 측정규격에 의한 완전관통과 부분관통의 평균속도를 의미한다.The bullet-proof performance (V50) of 1,550ft / sec means the average speed of full penetration and partial penetration when measuring 0.22 (Cal) FSP into the body armor at 1,550ft / sec.

이상에서 설명한 바와 같이 본 발명의 방탄복용 직물과 이로 제조된 방탄복은 총알에 의해 가해지는 충격에 대해 약점(Weak point)로 작용하는 꼬임부분이 없어서 작은 매수의 방탄복용 직물을 적층하여도 양호한 방탄성능을 발현하고, 방탄복용 직물의 적층매수가 감소하여 착용감도 향상된다.As described above, the body armor for body armor of the present invention and the body armor prepared therewith have no twisted portion acting as a weak point against the impact exerted by bullets. And the number of laminated sheets of the body armor is reduced, and the fit is also improved.

이하, 본 발명을 실시예 및 비교실시예를 통하여 보다 구체적으로 살펴본다.Hereinafter, the present invention will be described in more detail through Examples and Comparative Examples.
