Description
본 발명은 방탄용 직물에 관한 것으로서, 보다 구체적으로는 방탄성능이 우수한 방탄용 직물, 및 그를 이용한 방탄제품에 관한 것이다. The present invention relates to a ballistic fabric, and more particularly, to a ballistic fabric having excellent ballistic performance, and a ballistic product using the same.
방탄용 직물은 방탄복, 방탄헬멧, 방탄판 등 다양한 방탄제품에 사용되는 원단이다. 방탄제품은 탄환이나 포탄의 파면으로부터 인체를 보호하기 위한 제품으로서, 이와 같은 방탄제품의 방탄성능은 그 원단인 방탄용 직물의 방탄성능에 크게 좌우된다. Bulletproof fabrics are fabrics used in a variety of bulletproof products, such as body armor, bulletproof helmets, bulletproof boards. Bulletproof products are products for protecting the human body from the fracture of bullets or shells, the bulletproof performance of such bulletproof products is largely dependent on the bulletproof performance of the fabric for bulletproof fabrics.
종래의 방탄용 직물은 나일론 또는 아라미드 원사를 이용하여 제직공정(weaving)을 통해 제조되었다. 또한, 방탄용 직물이 수분을 장기간 흡수하게 되면 물성이 저하되어 결국 방탄특성이 떨어지는 문제가 발생할 수 있으므로, 상기 제직공정을 통해 얻어진 직물에 발수처리공정(water repellent treatment)을 수행하였다. Conventional antiballistic fabrics have been produced by weaving using nylon or aramid yarns. In addition, when the anti-ballistic fabric absorbs moisture for a long time, the physical properties may be degraded, and thus, the antiballistic property may be degraded. Thus, a water repellent treatment was performed on the fabric obtained through the weaving process.
이와 같은 방탄용 직물의 방탄특성은, 방탄용 직물을 구성하는 원사 및 직물의 구조 등에 의해 좌우되며, 현재까지 고강도 원사 및 최적의 직물 구조에 대해서 다양한 제안들이 있어왔지만, 아직까지 원하는 방탄특성을 갖는 방탄용 직물을 얻지는 못하고 있다. 그에 따라, 방탄용 직물의 적층수를 증가시키거나 또는 방탄용 직물 사이에 열경화성 수지를 추가하여 방탄제품을 제조함으로써 방탄용 직물의 방탄특성을 보완하는 방법들이 개발되었지만, 이는 적층수가 증가하거나 열경화성 수지가 추가됨에 따라 방탄제품의 중량이 커지는 단점이 있다. The anti-ballistic properties of such a bulletproof fabric depends on the structure of the yarn and the fabric constituting the bulletproof fabric, and various proposals have been made on the high strength yarn and the optimal fabric structure until now, but still have the desired antiballistic properties Bulletproof fabrics are not obtained. Accordingly, methods have been developed to increase the number of layers of bulletproof fabrics or to supplement the antiballistic properties of bulletproof fabrics by manufacturing a bulletproof product by adding a thermosetting resin between the bulletproof fabrics. As the weight of the bulletproof product is added, there is a disadvantage.
본 발명은 탄환이 방탄용 직물과 충돌한 후 방탄용 직물을 뚫고 진행할 때 탄환의 진행을 억제하기 위해 요구되는 방탄용 직물의 특성을 규명하고, 그와 같은 특성을 갖는 방탄용 직물 및 방탄 제품을 제공하는 것을 목적으로 한다. The present invention is to identify the characteristics of the bulletproof fabric required to suppress the progress of the bullet when proceeding through the bulletproof fabric after the bullet hit the bulletproof fabric, bulletproof fabric and bulletproof products having such characteristics It aims to provide.
탄환이 방탄용 직물과 충돌하면 방탄용 직물을 구성하는 원사가 파손되거나 또는 원사 사이의 간격이 벌어지면서 탄환이 직물 구조 사이를 뚫고 진행하게 된다. 따라서, 원사의 파손 및 원사 사이의 간격이 벌어지는 것을 최소화하여 탄환이 직물을 뚫고 진행하는 것을 억제함으로써 직물의 방탄특성을 향상시킬 수 있는 것이다. When the bullet collides with the bulletproof fabric, the yarn constituting the bulletproof fabric is broken or a gap is formed between the yarns, and the bullet passes through the fabric structure. Therefore, it is possible to improve the bulletproof characteristics of the fabric by minimizing the breakage of the yarn and the gap between the yarns to prevent the bullet from going through the fabric.
본 발명자는 방탄용 직물의 회전 관통저항력을 증진시킴으로써 탄환이 직물을 뚫고 진행하는 것을 억제하여 방탄용 직물의 방탄특성을 개선할 수 있으며, 이와 같은 회전 관통저항력의 증진은, 원사를 구성하는 멀티필라멘트의 섬도, 멀티필라멘트를 구성하는 모노필라멘트의 섬도, 및 위사와 경사 밀도를 최적화하고, 선택적으로, 미끄럼 방지제 또는 미끄럼 방지제와 발수제를 추가로 코팅함으로써 달성할 수 있음을 확인하여 본 발명을 완성하게 되었다. The present inventors can improve the ballistic resistance of the bulletproof fabric by suppressing the progression of the bullet through the fabric by improving the rotational penetration resistance of the bulletproof fabric, such enhancement of the rotational penetration resistance, the multifilament constituting the yarn The present invention was completed by optimizing the fineness of the monofilament, the fineness of the monofilament constituting the multifilament, the weft and the inclined density, and optionally, by additionally coating the antislip agent or the antislip agent and the water repellent agent. .

이하, 본 발명의 실시예에 대해서 상세히 설명하기로 한다.Hereinafter, embodiments of the present invention will be described in detail.
1. 방탄용 직물 및 방탄 제품1. Bulletproof fabrics and bulletproof products
본 발명에 따른 방탄용 직물은 위사 및 경사로 이루어지고, 상기 위사 및 경사를 구성하는 원사(Yarn)는 멀티필라멘트로 이루어지며, 방탄용 직물의 회전 관통저항력이 100이상이다. 상기 멀티필라멘트로는 전방향족 폴리아미드 멀티필라멘트를 이용할 수 있다. Bulletproof fabric according to the invention is made of a weft yarn and warp yarns, Yarn constituting the weft yarn and warp yarns made of multifilament, the rotational penetration resistance of the bulletproof fabric is 100 or more. As the multifilament, an wholly aromatic polyamide multifilament may be used.
상기 회전 관통저항력은 회전하는 소정의 압자에 의해 직물이 관통될 때까지의 압자 회전수로 측정된다. 도 1은 본 발명에 따른 회전 관통저항력 측정장치를 개략적으로 도시한 단면도로서, 도 1을 참조하여 본 발명에 따른 회전 관통저항력 측정방법에 대해서 설명하면, 방탄용 직물 (1) 1겹을 고정틀(3)에 고정하고, 반구형 압자(5)를 소정의 속도로 90°범위로 좌우회전시켜 직물이 관통될 때까지의 압자 회전수를 계산하여 관통저항력을 측정한다. The rotational penetration resistance is measured by the number of indenters until the fabric is penetrated by a predetermined indenter that rotates. 1 is a cross-sectional view schematically showing a device for measuring the rotational penetration resistance according to the present invention. Referring to FIG. 1, the method for measuring the rotational penetration resistance according to the present invention will be described. ), The hemispherical indenter 5 is rotated left and right at a predetermined speed in a 90 ° range, and the penetration resistance is measured by calculating the number of revolutions until the fabric is penetrated.
방탄용 직물의 회전 관통저항력이 100 이상이 되도록 하기 위해서는, 원사의 섬도, 원사의 제직밀도, 직물 제조공정 조건의 최적화 등이 필요하다. In order to make the rotational penetration resistance of the bulletproof fabric to be 100 or more, it is necessary to optimize the fineness of the yarn, the weaving density of the yarn, and the fabrication process conditions.
우선, 원사의 섬도와 관련해서는, 원사를 구성하는 멀티필라멘트의 섬도가 300 ~ 4500 데니어 범위가 바람직하다. 상기 멀티필라멘트의 섬도가 300 데니어 미만일 경우에는 직물의 회전 관통저항력이 저하되어 원하는 방탄특성을 얻지 못할 수 있으며, 상기 멀티필라멘트의 섬도가 4500 데니어를 초과할 경우에는 직물의 제직공정시 제직성이 떨어질 수 있다. 또한, 상기 멀티필라멘트를 구성하는 모노필라멘트는 섬도가 0.7 ~ 1.6 데니어 범위가 바람직하다. 섬도가 1.6 데니어 이하의 가는 모노필라멘트를 이용할 경우 동일한 섬도의 멀티필라멘트를 얻기 위해 보다 많은 개수의 모노필라멘트를 사용할 수 있고, 그에 따라 직물의 회전 관통저항력이 증진될 수 있으며, 섬도가 0.7 데니어 미만의 모노필라멘트를 이용할 경우에는 직물의 제직공정시 제직성이 떨어질 수 있다.First, regarding the fineness of the yarn, the fineness of the multifilament constituting the yarn is preferably in the range of 300 to 4500 denier. When the fineness of the multifilament is less than 300 denier, the rotational penetration resistance of the fabric may be lowered, and thus, the desired ballistic resistance may not be obtained. When the fineness of the multifilament exceeds 4500 denier, weaving may be poor during the weaving process of the fabric. Can be. In addition, the monofilament constituting the multifilament is preferably in the range of fineness 0.7 ~ 1.6 denier. If a monofilament with a fineness of 1.6 denier or less is used, more monofilaments can be used to obtain multifilaments of the same fineness, thereby increasing the rotational penetration resistance of the fabric, and the fineness of less than 0.7 denier If monofilament is used, weaving may be degraded during the weaving process of the fabric.
다음, 원사의 제직밀도와 관련해서는, 원사를 구성하는 멀티필라멘트의 경사밀도 및 위사밀도는 각각 5 ~ 20본/cm 범위가 바람직하다. 상기 경사밀도 및 위사밀도가 5본/cm 미만일 경우에는 직물의 회전 관통저항력이 저하되어 원하는 방탄특성을 얻지 못할 수 있으며, 상기 경사밀도 및 위사밀도가 20본/cm을 초과할 경우에는 직물 제직공정시 제직성이 떨어질 수 있다. Next, with respect to the weaving density of the yarn, the inclination density and the weft density of the multifilament constituting the yarn are preferably in the range of 5 to 20 bones / cm, respectively. When the warp density and the weft density are less than 5 bone / cm, the rotational penetration resistance of the fabric may be lowered to obtain desired antiballistic properties, and when the warp density and the weft density exceeds 20 bone / cm, the fabric weaving process may be performed. Weaving can be impaired.
다음, 직물 제조공정 조건의 최적화와 관련해서는, 미끄럼 방지제를 코팅하고 그에 더하여 직물의 발수처리시 발수제 조성을 최적화함으로써 얻어지는 직물의 회전 관통저항력을 증진할 수 있다. 이에 대해서는 후술하는 방탄용 직물의 제조방법에서 상세히 설명하기로 한다. Next, with regard to the optimization of the fabric manufacturing process conditions, it is possible to enhance the rotational penetration resistance of the fabric obtained by coating the anti-slip agent and in addition optimizing the water repellent composition in the water repellent treatment of the fabric. This will be described in detail in the method of manufacturing a bulletproof fabric described later.
이상과 같은 본 발명에 따른 방탄용 직물의 제조방법을 설명하면, 본 발명에 따른 방탄용 직물은 멀티필라멘트를 준비하는 공정, 및 상기 멀티필라멘트를 경사 및 위사로 하여 직물을 제직하는 공정을 통해 제조된다.Referring to the manufacturing method of the bulletproof fabric according to the present invention as described above, the bulletproof fabric according to the present invention is prepared through the process of preparing a multifilament, and the process of weaving the fabric with the multifilament as the warp and weft. do.
상기 멀티필라멘트를 준비하는 공정은, 방향족 디아민과 방향족 디에시드클로라이드를 중합용매 중에서 중합시킴으로써 방향족 폴리아미드 중합체를 제조하고, 그 후 상기 방향족 폴리아미드 중합체를 농황산 용매에 용해시켜 방사도프를 제조하고, 그 후 상기 방사도프를 방사구금을 통해 방사한 후 방사물을 응고시켜 전방향족 폴리아미드 멀티필라멘트를 제조하는 공정으로 이루어질 수 있다.In the step of preparing the multifilament, an aromatic polyamide polymer is prepared by polymerizing an aromatic diamine and an aromatic dieside chloride in a polymerization solvent, and then dissolving the aromatic polyamide polymer in a concentrated sulfuric acid solvent to prepare a spinning dope. Thereafter, the spinning dope may be spun through a spinneret, and then, the spinning material may be solidified to produce a wholly aromatic polyamide multifilament.
상기 전방향족 폴리아미드 멀티필라멘트는 섬도가 300 ~ 4500 데니어 범위가 바람직하고, 상기 멀티필라멘트를 구성하는 모노필라멘트는 섬도가 0.7 ~ 1.6 데니어 범위가 바람직함은 전술한 바와 같다. The wholly aromatic polyamide multifilament is preferably in the range of 300 ~ 4500 denier fineness, the monofilament constituting the multifilament is as described above that the fineness is preferably in the range of 0.7 to 1.6 denier.
상기 전방향족 폴리아미드 멀티필라멘트는 인장강도가 22g/d 이상인 것이 제조되는 직물의 방탄특성향상에 유리하다. The wholly aromatic polyamide multifilament is advantageous in improving the ballistic resistance of the fabric is produced that the tensile strength of 22g / d or more.
상기 직물을 제직하는 공정은 상기 전방향족 폴리아미드 멀티필라멘트를 경사 및 위사로 하며 평직(plain) 또는 바스켓직(basket)을 직물조직으로 하여 제직하는 공정으로 이루어질 수 있다. The process of weaving the fabric may comprise a process of weaving the warp and weft of the wholly aromatic polyamide multifilament, and the plain or basket weaving as a fabric structure.
상기 제직 공정시 경사밀도 및 위사밀도는 각각 5 ~ 20본/cm 범위 내로 조절하는 것이 바람직함은 전술한 바와 같다.As described above, the inclination density and the weft density during the weaving process are preferably adjusted within the range of 5 to 20 books / cm.
상기 직물의 제직공정 이후에는 미끄럼 방지제를 상기 직물에 코팅하여 회전 관통저항력을 증진시킬 수 있으며, 이는 미끄럼 방지제 조성물에 상기 직물을 침지 하는 미끄럼 방지 처리 공정을 통해 달성할 수 있다. After the weaving process of the fabric may be coated with the anti-slip agent to improve the rotational penetration resistance, this can be achieved through the anti-slip treatment process immersing the fabric in the anti-slip agent composition.
상기 미끄럼 방지제 조성물은, 직경이 0.1 내지 3㎛ 크기의 무기계 입자 또는 무기염에서 유도된 입자 0.1 내지 10중량%의 수용액으로 이루어질 수 있다. 상기 무기계 입자 또는 무기염에서 유도된 입자로는 이산화티타늄, 글라스 비드(glass bead) 등을 이용할 수 있으나, 반드시 그에 한정되는 것은 아니다. 상기 무기계 입자 또는 무기염에서 유도된 입자의 직경이 0.1 ㎛ 미만인 경우 분산성이 저하될 수 있고, 3㎛를 초과할 경우 직물에의 부착성이 저하될 수 있다. 또한, 상기 무기계 입자 또는 무기염에서 유도된 입자의 첨가량이 0.1 중량% 미만일 경우 회전 관통저항력을 증진시킬 수 없고, 그 첨가량이 10중량%를 초과할 경우 분산성이 저하될 수 있고 비용이 증가되어 경제성이 떨어질 수 있다. The anti-slip agent composition may be composed of an aqueous solution of 0.1 to 10% by weight of particles derived from inorganic particles or inorganic salts having a diameter of 0.1 to 3㎛ size. As the inorganic particles or the particles derived from the inorganic salts, titanium dioxide, glass beads, or the like may be used, but is not limited thereto. When the diameter of the inorganic particles or the particles derived from the inorganic salt is less than 0.1 μm, the dispersibility may be lowered, and when the diameter is more than 3 μm, the adhesion to the fabric may be reduced. In addition, when the addition amount of the inorganic particles or the particles derived from the inorganic salt is less than 0.1% by weight can not improve the rotational penetration resistance, if the addition amount is more than 10% by weight dispersibility may be lowered and the cost is increased Economics can fall.
또한, 상기 직물의 제직공정 이후에는, 직물에 대한 정련처리(Scouring treatment) 공정 및 발수처리(water repellent treatment) 공정을 수행할 수 있다. In addition, after the weaving process of the fabric, it is possible to perform a scouring treatment process and a water repellent treatment process for the fabric.
상기 정련처리 공정은 직물을 구성하는 전방향족 폴리아미드 멀티필라멘트에 부착되어 있는 유제나 이물질을 제거하는 공정으로서, 이와 같은 정련공정을 수행하지 않고 발수처리공정을 수행하게 되면 발수처리공정이 원활히 이루어지지 않게 되며 또한 직물의 유연성이 저하될 수 있다. The refining process is a process of removing the oil or foreign matter adhering to the wholly aromatic polyamide multifilament constituting the fabric, if the water repellent treatment process is performed without performing such a refining process is not smoothly made It is also possible to reduce the flexibility of the fabric.
상기 정련처리 공정은 40℃-100℃에서 NaOH 또는 Na2CO3와 같은 계면활성제를 이용하여 수행할 수 있고, 상기 계면활성제 처리 후에는 수세공정과 건조공정을 이어서 수행한다. The refining process may be carried out using a surfactant such as NaOH or Na 2 CO 3 at 40 ℃-100 ℃, after the surfactant treatment is followed by a washing step and a drying step.
상기 발수처리 공정은 직물이 수분을 흡수하지 않도록 처리하는 공정으로서, 직물을 구성하는 전방향족 폴리아미드 멀티필라멘트는 일반적으로 수분을 장기간 흡수하게 되면 물성이 저하되어 결국 직물의 방탄특성이 점차 떨어지는 문제가 발생하므로 직물에 발수처리를 수행하여 수분흡수로 인한 방탄특성 저하를 방지하는 것이다. 또한, 상기 발수처리 공정시의 발수제 조성을 조절함으로써 얻어지는 직물의 회전 관통저항력을 증진시킬 수 있다. The water-repellent treatment process is a process to prevent the fabric from absorbing moisture, the wholly aromatic polyamide multifilament constituting the fabric is generally a problem that the long-term absorption of water is deteriorated in physical properties and eventually the ballistic characteristics of the fabric is gradually reduced As it occurs, water repellent treatment is performed on the fabric to prevent deterioration of ballistic resistance due to water absorption. In addition, it is possible to improve the rotational penetration resistance of the fabric obtained by adjusting the water repellent composition during the water repellent treatment process.
상기 발수처리 공정은 전술한 바와 같이 정련 공정을 통해 직물의 표면에 부착된 이물질을 완전히 제거한 후, 발수제 조성물에 직물을 침지시키고, 건조하는 공정으로 이루어질 수 있다. As described above, the water repellent treatment process may be performed by completely removing the foreign matter adhered to the surface of the fabric through a refining process, and then immersing the fabric in the water repellent composition and drying.
상기 발수제로는 하드록실레이티드 퍼르플루오로알킬 에틸 아크릴레이트 코폴리머(Hydroxylated perfluoroalkylethyl acrylate copolymer) 25 ~ 35 중량%, 디프로필렌 글리콜(Dipropylene glycol) 10 ~ 15 중량% 및 물 50 ~ 65중량%로 이루어진 조성물의 1 ~ 5 중량% 수용액을 이용함으로써, 직물의 발수성 및 회전 관통저항력 모두를 증진시킬 수 있다. The water repellent is composed of 25 to 35% by weight of hardoxylated perfluoroalkylethyl acrylate copolymer, 10 to 15% by weight of dipropylene glycol and 50 to 65% by weight of water. By using 1-5% by weight aqueous solution of the composition, both the water repellency and the rolling penetration resistance of the fabric can be enhanced.
상기 하드록실레이티드 퍼르플루오로알킬 에틸 아크릴레이트 코폴리머는 직물에 발수성을 부여하는 역할을 하는 것으로서, 그 첨가량이 25 중량% 미만일 경우 원하는 직물의 발수성을 기대하기 어렵고, 그 첨가량이 35 중량%를 초과할 경우 직물의 회전 관통저항력이 저하될 수 있다. The hardoxylated perfluoroalkyl ethyl acrylate copolymer has a role of imparting water repellency to the fabric, when the addition amount is less than 25% by weight, it is difficult to expect the water repellency of the desired fabric, the addition amount is 35% by weight If exceeded, the rotational penetration resistance of the fabric may be lowered.
상기 디프로필렌 글리콜은 발수제 조성물의 성분이 균일하게 분산될 수 있도록 하는 역할을 하는 것으로서, 그 첨가량이 10 중량% 미만일 경우 그 분산기능이 떨어질 수 있고, 그 첨가량이 15 중량%를 초과할 경우 발수성이 떨어질 수 있다. The dipropylene glycol plays a role of uniformly dispersing the components of the water repellent composition, when the amount is less than 10% by weight of the dispersing function may fall, when the amount is more than 15% by weight of water repellency Can fall.
상기 조성물의 수용액 내 농도가 1중량% 미만이면 발수성 및 회전 관통저항력이 떨어질 수 있고, 5중량%를 초과하면 직물의 표면에 고형분이 과다 부착될 수 있다. When the concentration in the aqueous solution of the composition is less than 1% by weight, water repellency and rotational penetration resistance may drop, and when it exceeds 5% by weight, the solid may be excessively attached to the surface of the fabric.
한편, 전술한 미끄럼 방지 처리 공정을 상기 발수처리공정과 동시에 수행함으로써 미끄럼 방지제와 발수제를 동시에 코팅하여 제조공정을 단순화시킬 수 있다. 즉, 직물의 제직공정을 완료한 후, 전술한 직물에 대한 정련처리공정을 수행하고, 그후, 상기 발수제 조성물 및 미끄럼 방지제 조성물의 혼합물에 직물을 침지함으로써 직물에 대한 발수처리 및 미끄럼 방지처리를 동시에 수행할 수 있다. On the other hand, by performing the above-mentioned anti-slip treatment process simultaneously with the water repellent treatment process it is possible to simplify the manufacturing process by coating the anti-slip agent and the water repellent at the same time. In other words, after the weaving process of the fabric is completed, the above-described scouring process for the fabric is carried out, and then, by immersing the fabric in the mixture of the water repellent composition and the anti-slip agent composition at the same time to the water repellent treatment and anti-slip treatment of the fabric Can be done.
상기 발수처리 공정 이후에 직물에 열처리 공정을 수행할 수 있다. 상기 열처리 공정은 120-200℃에서 15-150초 정도로 수행할 수 있는데, 이때 열처리 온도가 120℃ 미만이거나 열처리 시간이 15초 미만이면 발수제의 부착성이 떨어질 수 있고, 온도가 200℃ 초과되거나 시간이 150초를 초과하면 직물에 손상을 주어 발수성 및 회전 관통저항력이 떨어질 수 있다. After the water repellent treatment process can be carried out a heat treatment process on the fabric. The heat treatment process may be performed at 120-200 ° C. for about 15-150 seconds. At this time, if the heat treatment temperature is less than 120 ° C. or the heat treatment time is less than 15 seconds, the adhesion of the water repellent may be lowered. If this time exceeds 150 seconds, the fabric may be damaged, resulting in poor water repellency and rolling penetration resistance.
이상과 같은 방법에 의해 제조된 본 발명에 따른 방탄용 직물은 회전 관통저항력이 100 이상이 되어 탄환이 직물 구조 사이를 뚫고 진행하는 것이 억제되어 방탄특성이 향상되며, 구체적으로는, 본 발명에 따른 방탄용 직물을 20매 적층할 경우, 그 방탄성능(V0)은 436m/s 이상으로 우수하게 된다. The bulletproof fabric according to the present invention manufactured by the above method has a rotational penetration resistance of 100 or more, thereby preventing the bullet from penetrating through the fabric structure, thereby improving the bulletproof property, specifically, according to the present invention. In the case of stacking 20 bulletproof fabrics, the bulletproof performance (V0) becomes excellent at 436 m / s or more.
또한, 본 발명은 상기와 같은 특성을 갖는 방탄용 직물을 이용한 방탄제품을 제공하는데, 상기 방탄제품으로는 방탄복, 방탄헬멧, 및 방탄판 등을 들 수 있다. 상기 방탄복, 방탄헬멧, 및 방탄판은 공지된 방법에 의해 제조할 수 있으며, 이때, 상기 방탄헬멧 및 방탄판은 전술한 발수처리공정을 수행하지 않을 수 있다. In addition, the present invention provides a bulletproof article using a bulletproof fabric having the characteristics as described above, the bulletproof article may include a body armor, a bulletproof helmet, a bulletproof plate and the like. The body armor, bulletproof helmet, and bulletproof plate may be manufactured by a known method, wherein the bulletproof helmet and bulletproof plate may not perform the above-described water repellent treatment process.

회전 관통저항력 측정Rotational penetration resistance measurement
상기 실시예 및 비교예에 따라 제조된 방탄용 직물을 15cm × 30cm으로 잘라 샘플을 준비한 후, 도 1에 따른 회전 관통저항력 측정장치를 이용하여 회전 관통저항력을 측정하였다. 구체적으로는, 15cm × 30cm 크기의 직물 샘플(1) 1겹을 고정틀(3)에 고정하고, 95kg의 하중이 걸린 직경 1.7cm의 반구형 압자(5)를 상기 직물 샘플(1)의 중앙지점에서 30rpm의 속도로 90°범위로 좌우회전시켜 직물 샘플(1)이 관통될 때까지의 회전수를 계산하였다. 여기서, 90°범위로 좌우회전한 경우를 1회전으로 정의하고, 직경 1.7cm 부분에 해당하는 반구형 압자(5) 부분이 직물 샘플(1)을 통과하는 시점을 관통시점으로 정의한다. 그 결과는 하기 표 2와 같다. After cutting the bullet-proof fabric prepared according to the Examples and Comparative Examples to 15cm × 30cm to prepare a sample, the rotational penetration resistance was measured using the rotational penetration resistance measuring apparatus according to FIG. Specifically, a single 15 cm × 30 cm
방탄성능 측정Bulletproof performance measurement
상기 실시예 및 비교예에 따라 제조된 방탄용 직물을 40cm × 40cm으로 잘라 20겹을 겹쳐서 샘플을 준비한 후, 준비된 각각의 샘플에 대해서 NIJ(National Institute of Justice) 규격에 따라 방탄 시험을 실시하였다. 방탄 시험시 사용된 탄환은 .44mag 이다. 그 결과는 하기 표 3과 같다. 하기 표에서 V0은 탄환이 목표물를 통과하지 못하는 최대 속도이다. After cutting the bulletproof fabric prepared according to the above Examples and Comparative Examples to 40cm × 40cm to prepare a sample of 20 ply overlap, the samples were subjected to a bulletproof test according to the NIJ (National Institute of Justice) standards. The bullet used in the bulletproof test was .44 mag. The results are shown in Table 3 below. In the table below, V0 is the maximum velocity at which the bullet does not pass the target.
