技术领域technical field
本发明涉及防弹织物及其制备方法。更具体而言，本发明涉及一种防弹织物及其制备方法，所述防弹织物表现出改善的抗损伤性能，并将即使在苛刻环境下经长时间使用后的防弹性能劣化减少至最低限度。The present invention relates to bulletproof fabric and its preparation method. More particularly, the present invention relates to a ballistic-resistant fabric exhibiting improved damage resistance and minimizing deterioration of ballistic-resistant performance even after prolonged use under severe environments, and a method for producing the same.
背景技术Background technique
防弹衣是一种开发出来用于保护人体免受炮弹碎片或子弹伤害的服装。因此，对防弹衣最重要的要求就是防弹性能。然而，由于构成防弹衣的高强度纤维容易受到水的损伤，因此产生了严重的问题，例如在苛刻环境下或经长时间使用后，防弹衣的防弹性能出现劣化。Body armor is a type of clothing developed to protect the human body from shell fragments or bullets. Therefore, the most important requirement for body armor is ballistic performance. However, since the high-strength fibers constituting the body armor are easily damaged by water, serious problems have arisen, such as deterioration of the ballistic performance of the body armor under harsh environments or after long-term use.
为了解决上述问题，本申请人曾提出一种使用防弹织物的防水处理方法(韩国专利公布号10-2010-0023491)。然而，通过防水处理而使防弹织物具有的防水性无法长时间保持的问题仍然存在。也就是说，由于外部环境和/或时间推移，通过防水处理而粘附在防弹织物上的防水剂成分(例如碳氟化合物)不利地容易从该防弹织物上脱除。结果是，常规的防弹衣存在严重的问题，即在苛刻环境下或经长时间使用后，其防弹性能发生显著的劣化。In order to solve the above problems, the present applicant has proposed a water repellent treatment method using bulletproof fabric (Korean Patent Publication No. 10-2010-0023491). However, there remains a problem that the water repellency possessed by the bulletproof fabric cannot be maintained for a long time by the water repellent treatment. That is, the water repellant component (such as fluorocarbon) adhered to the bulletproof fabric by the water repellent treatment is disadvantageously easily detached from the bulletproof fabric due to the external environment and/or the lapse of time. As a result, conventional bulletproof vests have serious problems in that their bulletproof performance is significantly deteriorated under harsh environments or after being used for a long period of time.
同时，穿着防弹衣的使用者应该可以方便地移动。因此，除防弹性能外，穿着感也是对防弹衣的重要要求。当防弹衣过于沉重或僵硬时，由于劣化的穿着感，即使该防弹衣表现出优异的防弹性能，也不认为它是优良的防弹衣。考虑到穿着感，防弹衣应该用硬挺度(柔韧度)为10N至70N的软质防弹织物来制备。然而，普通的软质防弹织物具有抗损伤性能无法令人满意的局限。At the same time, users wearing body armor should be able to move easily. Therefore, in addition to bulletproof performance, wearing comfort is also an important requirement for bulletproof vests. When the body armor is too heavy or stiff, it is not considered to be excellent body armor even if the body armor exhibits excellent ballistic performance due to deteriorated wearing feeling. Considering the feeling of wearing, body armor should be prepared with a soft bulletproof fabric with a stiffness (flexibility) of 10N to 70N. However, ordinary soft bulletproof fabrics have unsatisfactory damage resistance limitations.
抗损伤性能是防弹衣的一项重要的防弹性能。当子弹的物理冲击施加到防弹织物上时，防弹织物发生局部变形，且碰撞表面的形变扩大至防弹织物的后表面，可能会发生背面形变超出可接受的安全距离的情况。防弹织物严重的背面变形可能对使用者造成致命的伤害。Damage resistance is an important anti-ballistic performance of body armor. When the physical impact of a bullet is applied to the bulletproof fabric, the bulletproof fabric is locally deformed, and the deformation of the impact surface is extended to the rear surface of the bulletproof fabric, and it may happen that the rear surface deforms beyond the acceptable safety distance. Severe back deformation of the bulletproof fabric may cause fatal injury to the user.

具体实施方式Detailed ways
本领域的技术人员将会理解，在不背离本发明的范围和精神的情况下，可以进行各种修改、添加和替换。因此，本发明包括落入权利要求书中所述的本发明范围内的全部替换和修改及其等同物。Those skilled in the art will understand that various modifications, additions and substitutions can be made without departing from the scope and spirit of the present invention. Accordingly, the present invention includes all replacements and modifications and their equivalents falling within the scope of the present invention described in the claims.
下文中，将参照附图详细描述根据本发明的一个实施方案的防弹衣及其制备方法。Hereinafter, a body armor according to an embodiment of the present invention and a manufacturing method thereof will be described in detail with reference to the accompanying drawings.
本发明的防弹织物包括由高分子量聚乙烯纤维、芳族聚酰胺纤维和聚苯并噁唑纤维中至少一种高强度纤维制成的织物。The bulletproof fabric of the present invention includes a fabric made of at least one high-strength fiber selected from high-molecular-weight polyethylene fibers, aramid fibers and polybenzoxazole fibers.
在本发明的一个实施方案中，使用高分子量聚乙烯纤维、芳族聚酰胺纤维和聚苯并噁唑纤维中的一种作为经纱和纬纱来织造织物。选择性地，可以分别使用不同种类的高强度纤维作为经纱和纬纱。并且，所述织物的经纱和纬纱可以包含两种或更多种不同种类的高强度纤维。In one embodiment of the present invention, a fabric is woven using one of high molecular weight polyethylene fibers, aramid fibers, and polybenzoxazole fibers as warp and weft yarns. Alternatively, different kinds of high-strength fibers may be used as warp and weft, respectively. Also, the warp and weft of the fabric may contain two or more different kinds of high-strength fibers.
可选地，本发明的织物可以是包含多个层的单向织物。每个层包含大体平行排列的高强度纤维，且相邻层的高强度纤维彼此交叉。Alternatively, the fabric of the present invention may be a unidirectional fabric comprising multiple layers. Each layer contains high-strength fibers arranged substantially in parallel, and the high-strength fibers of adjacent layers cross each other.
可选地，本发明的织物可以是单纤维不规则排列其中的毡。Alternatively, the fabric of the present invention may be a mat in which single fibers are randomly arranged.
下文中，将详细描述使用全芳基聚酰胺纤维(一种芳族聚酰胺纤维)作为经纱和纬纱来织造织物的方法。Hereinafter, a method of weaving a fabric using a wholly aramid fiber (a type of aramid fiber) as warp and weft will be described in detail.
首先，为了制备全芳基聚酰胺纤维，使芳族二胺和芳族二酰氯在聚合反应溶剂中聚合，制备芳基聚酰胺聚合物。将所制的芳基聚酰胺聚合物溶解在浓缩溶剂中，制备纺丝液。使该纺丝液通过喷丝头的多个孔，然后将其凝固，制得复丝。First, to prepare wholly aramid fibers, aromatic diamine and aromatic diacid chloride are polymerized in a polymerization solvent to prepare an aramid polymer. The prepared arylamide polymer was dissolved in a concentrated solvent to prepare a spinning solution. This spinning solution is passed through a plurality of holes of a spinneret and then solidified to produce a multifilament.
具有预定细度的复丝可以包含更多细度降低的单丝。根据本发明的一个实施方案的复丝包含细度为1.6旦尼尔或小于1.6旦尼尔的较细单丝，从而包含相对更多的单丝。因此，由该复丝织造的织物能够表现出改善的冲击吸收性能。A multifilament having a predetermined fineness may contain more monofilaments of reduced fineness. The multifilament according to one embodiment of the present invention includes thinner monofilaments having a fineness of 1.6 denier or less, thereby including relatively more monofilaments. Therefore, fabrics woven from the multifilament can exhibit improved shock absorption performance.
同时，难以使用细度低于0.7旦尼尔的复丝来织造织物。因此，就易于织造而言，构成复丝的单丝优选具有0.7旦尼尔或大于0.7旦尼尔的细度。Meanwhile, it is difficult to weave fabrics using multifilaments with a fineness below 0.7 denier. Therefore, the monofilament constituting the multifilament preferably has a fineness of 0.7 denier or more in terms of ease of weaving.
根据本发明的一个实施方案的全芳基聚酰胺复丝包含400到1,600根细度为0.7至1.6旦尼尔的单丝。就防弹织物的防弹性能而言，该全芳基聚酰胺复丝具有22g/d或大于22g/d的抗张强度。本发明并不特别局限于上述的单丝的数目和细度以及复丝的抗张强度。The wholly aramid multifilament according to one embodiment of the present invention includes 400 to 1,600 monofilaments having a fineness of 0.7 to 1.6 denier. In terms of ballistic performance of the bulletproof fabric, the wholly aramid multifilament has a tensile strength of 22 g/d or more. The present invention is not particularly limited to the number and fineness of the monofilaments and the tensile strength of the multifilaments mentioned above.
可以采用平纹织造或方平织造来进行所述织物的织造。经密和纬密可以为5至15pcs/cm，所得到的织物可以具有5,000至10,000N/5cm的抗张强度。本发明并不特别局限于上述的织物的经密、纬密和抗张强度。The weaving of the fabric may be performed using a plain weave or a basket weave. The warp and weft densities may be 5 to 15 pcs/cm, and the resulting fabric may have a tensile strength of 5,000 to 10,000 N/5cm. The present invention is not particularly limited to the above-mentioned warp density, weft density and tensile strength of the fabric.
在制备织物后，可以进行精练工序以去除粘附于高强度纤维上的油或杂质。After the fabric is prepared, a scouring process can be performed to remove oil or impurities adhering to the high-strength fibers.
通常而言，可以在高强度纤维卷绕在机芯部上之前，立即将纺纱油剂施用在该高强度纤维的表面上。当在油粘附于纤维表面的状态下对织物进行防水处理时，防水剂与织物之间无法获得粘合力。结果是，随着时间的推移，会发生防水性的迅速劣化并导致防弹性能的劣化。因此，优选在防水处理前进行所述精练工序，以去除粘附于高强度纤维上的油或杂质。Generally, the spinning finish can be applied to the surface of the high-strength fiber immediately before the high-strength fiber is wound on the core. When the fabric is waterproofed in a state where the oil adheres to the surface of the fiber, the adhesion between the waterproofing agent and the fabric cannot be obtained. As a result, rapid deterioration of water resistance occurs over time and leads to deterioration of ballistic performance. Therefore, it is preferable to perform the scouring process before the water repellent treatment to remove oil or impurities adhering to the high-strength fibers.
上述精练工序可以在40至100℃下使用包含表面活性剂如NaOH和/或Na2CO3的精练剂来进行。将所述织物用精练剂处理后，用水洗涤，然后进行干燥。The above-mentioned scouring process may be performed at 40 to 100° C. using a scouring agent containing a surfactant such as NaOH and/or Na2CO3. After the fabric has been treated with a scouring agent, it is washed with water and then dried.
接下来，用本发明的包含碳氟化合物和硬度增强树脂的防水剂处理所述织物，在高强度纤维上形成防水层。Next, the fabric is treated with the waterproofing agent of the present invention comprising a fluorocarbon and a hardness-enhancing resin to form a waterproofing layer on the high-strength fibers.
所述碳氟化合物的作用是赋予织物防水性。可以使用羟基化全氟烷基乙基丙烯酸酯共聚物(hydroxylated perfluoroalkylethyl acrylate copolymer)作为所述碳氟化合物。The function of the fluorocarbon is to impart water repellency to the fabric. A hydroxylated perfluoroalkylethyl acrylate copolymer may be used as the fluorocarbon.
所述硬度增强树脂增强织物的硬度，从而抑制由冲击所造成的防弹织物的背面形变。可以使用聚醋酸乙烯酯树脂、聚酯树脂、聚丙烯酸酯树脂、三聚氰胺树脂或其两种或更多种的混合物作为所述硬度增强树脂。The hardness-enhancing resin enhances the hardness of the fabric, thereby suppressing deformation of the back surface of the ballistic fabric caused by impact. Polyvinyl acetate resin, polyester resin, polyacrylate resin, melamine resin, or a mixture of two or more thereof may be used as the hardness enhancing resin.
可选地，本发明的防水剂还可以包含交联剂。所述交联剂可以是异氰酸酯化合物，例如甲苯二异氰酸酯或二苯基甲烷-4,4'-二异氰酸酯。交联剂增强赋予织物防水性的碳氟化合物与织物之间的粘合，从而使得防弹织物即使在苛刻环境下经长时间使用后，仍能够持续保持优异的防弹性能。Optionally, the waterproofing agent of the present invention may further contain a crosslinking agent. The crosslinking agent may be an isocyanate compound such as toluene diisocyanate or diphenylmethane-4,4'-diisocyanate. The cross-linking agent strengthens the bond between the fluorocarbon that makes the fabric water repellent and the fabric, allowing the ballistic fabric to maintain its excellent ballistic performance even after prolonged use in harsh environments.
可选地，本发明的防水剂还可以包含消泡剂以去除泡沫，例如二丙二醇。Optionally, the waterproofing agent of the present invention may also contain a defoamer to remove foam, such as dipropylene glycol.
可选地，本发明的防水剂还可以包含pH调节剂，例如马来酸。Optionally, the water repellent of the present invention may also contain a pH regulator such as maleic acid.
可选地，本发明的防水剂还可以包含乳化稳定剂，例如苹果酸。Optionally, the water repellent of the present invention may also contain an emulsion stabilizer, such as malic acid.
根据本发明的一个实施方案的防水剂包含0.5至10重量%的碳氟化合物、0.5至10重量%的硬度增强树脂、0.5至5重量%的交联剂、0.02至2重量%的消泡剂、0.02至2重量%的pH调节剂、0.1至2重量%的乳化稳定剂和69至98.36重量%的水。A waterproofing agent according to one embodiment of the present invention comprises 0.5 to 10% by weight of fluorocarbons, 0.5 to 10% by weight of hardness-enhancing resins, 0.5 to 5% by weight of crosslinking agents, and 0.02 to 2% by weight of antifoaming agents , 0.02 to 2% by weight of a pH regulator, 0.1 to 2% by weight of an emulsion stabilizer, and 69 to 98.36% by weight of water.
当碳氟化合物的含量低于0.5重量%时，不能获得所需的防水性能；而当其含量超过10重量%时，防水性的提高幅度不大，却可能使防弹织物的柔韧性降低。When the content of fluorocarbons is less than 0.5% by weight, the desired waterproof performance cannot be obtained; while when the content exceeds 10% by weight, the improvement of water resistance is not large, but the flexibility of the bulletproof fabric may be reduced.
当硬度增强树脂的含量低于0.5重量%时，几乎不表现出防弹织物抗损伤性能的改善；而当其含量超过10重量%时，使得防弹织物的柔韧性劣化，而且由这种防弹织物制作的防弹衣在穿着感和防水性上也表现出大幅度的劣化。When the content of the hardness-enhancing resin is less than 0.5% by weight, the improvement of the anti-damage performance of the bulletproof fabric is hardly exhibited; and when the content exceeds 10% by weight, the flexibility of the bulletproof fabric is deteriorated, and it is made of this bulletproof fabric The body armor also showed a substantial deterioration in wearing feeling and water resistance.
当交联剂的含量低于0.5重量%时，不能使防水性保持在所需水平；而当其含量超过5重量%时，只有制备成本不利地提高而没有其它效果。When the content of the crosslinking agent is less than 0.5% by weight, water repellency cannot be maintained at a desired level; while when the content exceeds 5% by weight, only the production cost is disadvantageously increased without other effects.
当消泡剂的含量低于0.02重量%时，去除泡沫的功能可能被劣化；而当其含量超过2重量%时，使得用于保持性能(例如防水性、柔韧性、抗损伤性能以及防水性)的其它成分的比例发生劣化，因此这些性能无法得到改善。When the content of the antifoaming agent is less than 0.02% by weight, the function of removing foam may be deteriorated; while when the content exceeds 2% by weight, the function for maintaining properties (such as water resistance, flexibility, damage resistance, and water resistance) may be deteriorated. ) deteriorates in proportion to other components, so these properties cannot be improved.
当pH调节剂的含量低于0.02重量%时，不能将防水剂的pH控制在所需范围内；而当其含量超过2重量%时，使得用于保持性能(例如防水性、柔韧性、抗损伤性能以及防水性)的其它成分的比例发生劣化，因此这些性能无法得到改善。When the content of the pH adjuster is less than 0.02% by weight, the pH of the water repellent cannot be controlled within the desired range; while when the content exceeds 2% by weight, it is difficult to maintain properties (such as water resistance, flexibility, resistance, etc.) Damage performance and water resistance) are degraded in proportion to other components, so these performances cannot be improved.
乳化稳定剂在用量低于0.1重量%时不能发挥稳定作用，而在用量超过2重量%时则可能造成织物物理性能的劣化。The emulsion stabilizer cannot exert a stabilizing effect when the amount is less than 0.1% by weight, and may cause deterioration of the physical properties of the fabric when the amount exceeds 2% by weight.
用防水剂处理所述织物包括：将防水剂施用在织物上，和对施用了防水剂的织物进行热处理。Treating the fabric with the water repellant includes applying the water repellent to the fabric, and heat-treating the fabric to which the water repellant has been applied.
防水剂对织物的施用可以通过例如填充、涂布、浸渍、喷涂、刷涂或涂膜的方法来进行。根据本发明的一个实施方案，通过将织物浸入充分搅拌的防水剂中而使防水剂浸渍到该织物中。The application of the water repellent to the fabric can be carried out by methods such as filling, coating, dipping, spraying, brushing or film coating. According to one embodiment of the present invention, the water repellent is impregnated into the fabric by immersing the fabric in a well stirred water repellent.
对施用了防水剂的织物的热处理可以在120至200℃下进行15至150秒。通过该热处理而去除水，使防水剂得到固化，并最终形成防水层。当热处理温度低于120℃或热处理时间短于15秒时，可能使防水处理效果发生劣化；而当热处理温度超过200℃或热处理时间超过150秒时，织物可能被损坏。The heat treatment of the fabric to which the water repellent is applied may be performed at 120 to 200° C. for 15 to 150 seconds. Water is removed by this heat treatment, the water repellent is cured, and finally a water repellent layer is formed. When the heat treatment temperature is lower than 120°C or the heat treatment time is shorter than 15 seconds, the waterproof treatment effect may be deteriorated; and when the heat treatment temperature exceeds 200°C or the heat treatment time exceeds 150 seconds, the fabric may be damaged.
采用本发明的方法制备的防弹织物具有10至70N的硬挺度(柔韧度)。硬挺度为防弹织物的柔韧性指标，其按照ASTM D4032通过圆形弯曲法来测量。当防弹织物的硬挺度低于10N时，防弹织物的强度过低，使得防弹性能特别是抗损伤性能较差。另一方面，当织物的硬挺度超过70N时，防弹织物缺乏柔韧性，而且由这种防弹织物制作的防弹衣不具有穿着感。The bulletproof fabric prepared by the method of the present invention has a stiffness (flexibility) of 10 to 70N. Stiffness is an indicator of the flexibility of ballistic fabrics, which is measured by the circular bend method according to ASTM D4032. When the stiffness of the bulletproof fabric is lower than 10N, the strength of the bulletproof fabric is too low, making the bulletproof performance, especially the damage resistance performance, poor. On the other hand, when the stiffness of the fabric exceeds 70N, the bulletproof fabric lacks flexibility, and the bulletproof vest made of this bulletproof fabric does not have a sense of wearing.
并且，按照NIJ Level IIIA的规定，使用平均速度为44Mag.的子弹测得的本发明的防弹织物中的背面形变为44mm或小于44mm。即，尽管本发明的防弹织物具有优异的柔韧性，但同时也表现出改善的抗损伤性能。And, according to the regulations of NIJ Level IIIA, the back deformation in the bulletproof fabric of the present invention measured by a bullet with an average speed of 44 Mag. is 44 mm or less. That is, although the bulletproof fabric of the present invention has excellent flexibility, it also exhibits improved damage resistance.
通过用包含聚醋酸乙烯酯树脂作为硬度增强树脂的防水剂处理织物而制备的防弹织物满足10至70N的硬挺度要求，并表现出背面形变为40mm或小于40mm的优异的抗损伤性能。即，当使用包含聚醋酸乙烯酯树脂作为硬度增强树脂的防水剂时，能够制得具有通常对于良好的防弹衣穿着感所需程度的柔韧性以及改善的抗损伤性能的防弹织物。The bulletproof fabric prepared by treating the fabric with a water repellant containing polyvinyl acetate resin as a hardness-enhancing resin meets the stiffness requirement of 10 to 70 N and exhibits excellent damage resistance with a backside deformation of 40 mm or less. That is, when a water repellent comprising polyvinyl acetate resin as a hardness enhancing resin is used, a ballistic fabric having a degree of flexibility generally required for good body armor wearing feeling and improved damage resistance can be produced.
本发明的防弹织物具有IV至V级的初始防水性(初始抗表面润湿性)，且该防弹织物在摩擦500次后的防水性为IV级以上。所述防水性是指防弹织物的防水性，其基于ISO4920:1981通过喷雾法来测量。使用Shiefer型磨损试验机(SAT-250)进行对防弹织物的摩擦。The bulletproof fabric of the present invention has initial waterproofness (initial resistance to surface wetting) of grades IV to V, and the waterproofness of the bulletproof fabric after rubbing 500 times is above grade IV. The water resistance refers to the water resistance of the ballistic fabric, which is measured by the spray method based on ISO4920:1981. Rubbing against ballistic fabrics was performed using a Shiefer type abrasion tester (SAT-250).
本发明的防弹织物具有IV至V级的初始防水性(初始抗表面润湿性)，而且即使在500次摩擦后仍保持IV级以上的高防水性。这意味着本发明的防弹织物即使经长时间使用后仍保持优异的防水性，结果是，能够将由吸湿造成的防弹性能劣化减少至最低限度。The bulletproof fabric of the present invention has initial waterproofness (initial resistance to surface wetting) of grades IV to V, and still maintains high waterproofness above grade IV even after 500 rubbings. This means that the bulletproof fabric of the present invention maintains excellent water repellency even after a long period of use, and as a result, deterioration of bulletproof performance due to moisture absorption can be minimized.
并且，本发明的防弹织物具有IV至V级的防雨性(压力下的防水性，Bundesmann试验，10分钟)。所述防弹织物的防雨性是指防弹织物在苛刻环境下的防水性，即表示防弹性能稳定水平的指标，其按照ISO9685:1992方法测量。And, the ballistic fabric of the present invention has a rainproof property of class IV to V (water resistance under pressure, Bundesmann test, 10 minutes). The rain resistance of the bulletproof fabric refers to the water resistance of the bulletproof fabric in harsh environments, which is an indicator of the stable level of bulletproof performance, which is measured according to the ISO9685:1992 method.
可以使用包括10至50片本发明这样制备的防弹织物的层合制品来制备防弹衣。所制的防弹衣表现出优异的性能，例如防水性、柔韧性和抗损伤性能，而且即使在苛刻环境下经长时间使用后仍可将防弹性能的劣化减少至最低限度。Body armor can be produced using a laminate comprising 10 to 50 pieces of the thus prepared ballistic fabric of the present invention. The resulting body armor exhibits excellent properties such as water resistance, flexibility, and damage resistance, and can minimize the deterioration of ballistic performance even after prolonged use in harsh environments.
