防弹物品
发明背景
1.发明领域
本发明涉及防弹物品领域。
2.相关技术的描述
在所述的领域中目前所需要的是提供一些例如背心、外衣等类似的物品,其具有改善的防弹性,与此同时对于穿着者来说具有舒适感。现有技术是尽力来增加物品的防弹性,其集中的焦点或是增加强度或是减少用于其物品中纤维的纤度。
例如,国际专利公开号No.WO93/00564公开的防弹结构使用了一些由高强度的对-芳族聚酰胺纱线织造而成的织物层。
美国专利No.4,850,050公开了由对-芳族聚酰胺纱线制成的防弹衣,其纱线包括低的单独线性密度的长丝。根据该发明制成的防弹衣的防弹性能据报道声称比较现有技术的织物改善了5%以上。
Melliand Textiberichte,Structure and Action ofBullet-Resistant Protective Vests,No.6,463-8页(1981)公开由细芳族聚酰胺纱线,例如220或440分特制成的织物,其比较粗纱线制成的织物提供有更好的防弹保护性。
美国专利No.5,187,003公开了一种用于防弹的织物,其在经向和纬向方向上具有不同的纤维。对于织物覆盖系数方面,其所表述的具有覆盖系数小于0.6的织物对于有效防弹保护来说是太松散了。
美国专利No.4287607揭示了一种防弹背心,其是由一些松散织造的芳族聚酰胺纤维的双布层制成,并且具有置于双织造布层之间的尼龙薄膜或尼龙织物。这些双布层具有如在此所限定的约0.71的织物紧密系数。
发明概述
本发明涉及一种柔性防弹物品,该物品包括数个具有2至10kg/m2面密度的织物层,其中至少两个织物层松散地被织造。松散织造织物层包括以0.3至0.6织物紧密系数织造的织物并且使用连续的长丝纱线制成,所述纱线具有至少200分特的线性密度,至少10克/分特的强度和至少150克/分特的拉伸模量。为固定这些层,相邻的松散织造织物层通过某些方式连接在一起以便限制松散织造织物层的彼此相对运动。
详细描述
本发明涉及一种柔性防弹物品。所述的物品包括数个织造织物层,其中至少两个层松散地被织造。松散织造层被连接在一起以限制这些层的彼此相对运动。该物品出人意料地呈现改进的防弹性。
本发明人已发现,当物品包括以纱线织造成少于0.6紧密系数的织物层时,织物的防弹性会有显著的改善。应该确信的是,低达0.3的紧密系数提供有改进的防弹性。正如在此所使用的,如同应用于织物层的术语,“松散地织造”意味着一种被织造成具有从约0.3至约0.6的紧密系数纱线的织物层。
在本发明之前,防弹织物是被紧密织造的。在与现有技术的认识完全相反的研究过程中,本发明人在此所揭示的松散织造的织物呈现有改进的防弹性。尽管具有任何减少紧密系数的任何织物可料到表现出某些改进,但大多数的改进被发现在紧密系数小于0.6处。随着紧密系数的进一步减少,防弹性进一步被改进,直到紧密系数达到约0.3,此时织物织纹是太松散以至于将需要一不能接受的高面密度,以便有效的防弹。
本发明的防弹物品是使用数层防护织物而制成的,并且包括至少两层松散的织造织物。为了固定这些织物层,松散的织造层通过某些方式而被固定在一起,以限制这些层彼此相对的运动。这些固定方式可以是用于把织物层固定在一起的任何常规方式,例如缝纫,缝编,粘合和/或用胶带粘贴。至于如何把松散的织造层缝纫和/或缝编在一起并没有限定。缝纫和/或缝编可以是绕着这些层的边缘,或穿过这些层,例如通过对角线缝纫和/或缝编或类似棉被的缝纫和/缝编。
织物的其他层也可以通过某些固定方式而被固定在一起,但是这些其他层被固定在一起以至于这些层彼此没有相对运动并非是关键性的。
本发明的防弹物品的结构与抗刀刺透物品相比较,其中抗刀刺透物品中防护织物的相邻层是不固定在一起的,而是彼此相对自由运动的,以便增加该物品的抗刀刺透性。
在这里,本发明完全是用织造织物构成的,而无需刚性板或小片并且无需基质树脂或粘合剂涂覆或浸渍织物材料。然而,这些刚性板或小片或基质树脂或粘合剂可用于本发明的物品中。
本发明的物品比现有技术的传统防弹结构更加柔软,重量更轻,触摸更软,穿着更舒适,和更加柔韧。
本发明的织物,包括松散织造织物层是全部或者部分由具有至少10克/分特的强度和至少150克/分特的拉伸模量的纱线制成的。这样的纱线可以是由芳族聚酰胺,聚烯烃,聚苯并噁唑,聚苯并噻唑等制成;并且如果需要的话,织物可以是由这些纱线的混合物制成。例如,织物可包括在纬纱方向上的一种类型的纱线和在纬纱方向的一不同类型的纱线。
“芳族聚酰胺”是指一种聚酰胺,其中酰胺键(-CO-NH-)的至少85%是直接连接在两个芳基环上。合适的芳族聚酰胺纤维已描述于人造纤维-科学与技术,第2卷,标题为芳族聚酰胺形成的纤维,p297,作者W.Black等人,Interscience Publishers,1968。芳族聚酰胺纤维还公开在US4,172,938;US3,869,429;US3,819,587;US3,673,143;US3,354,127和US3,094,511中。
添加剂能够与芳族聚酰胺一起使用,并且已经发现最多达10重量%的其它聚合物材料可以与芳族聚酰胺共混,或者可以使用最多达10%的取代芳族聚酰胺的二胺的其它二胺或最多达10%取代芳族聚酰胺的二酰氯的其它二酰氯的共聚物。
对-芳族聚酰胺是本发明的芳族聚酰胺纱线纤维中的基本聚合物,并且聚(对苯二甲酰对苯二胺)(PPD-T)是优选的对芳族聚酰胺。PPD-T是指由对苯二胺和对苯二酰氯等摩尔聚合获得的均聚物,以及通过与对苯二胺一起引入少量其它二胺和与对苯二酰氯一起引入少量其它二酰氯获得的共聚物。作为一般原则,其它二胺和其它二酰氯可以用最多达约为对苯二胺或对苯二酰氯的10摩尔%的用量或可能略高,条件仅仅是其它二胺和二酰氯没有干扰聚合反应的反应性基团。PPD-T还指由引入其它芳族二胺和其它芳族二酰氯获得的共聚物,例如2,6-萘二酰氯或氯代或二氯代对苯二酰氯或3,4’-二氨基二苯基醚。PPD-T的制备描述在US3,869,429;US4,308,374;和US4,698,414中。
“聚烯烃”是指聚乙烯或聚丙烯。聚乙烯是指主要为线性的聚乙烯材料,其具有优选大于1百万的分子量,可含有少量支链或每100个主链碳原子不超过5个改性单元的共聚单体,并且其还可含有与其混合的不大于约50重量%的一种或多种聚合添加剂,如烯烃-1-聚合物,特别是低密度聚乙烯、聚丙烯等,或者通常引入的低分子量添加剂例如抗氧化剂、润滑剂、紫外线遮蔽剂、着色剂等。这在扩展链聚乙烯(ECPE)中是公知的。类似地,聚丙烯是主要为线性的聚丙烯材料,其具有优选大于1百万的分子量。高分子量线性聚烯烃纤维是可购得到的。聚烯烃纤维的制备在US4,457,985中讨论。
聚苯并噁唑和聚苯并噻唑优选的是由以下结构的链节组成:
Figure A0280816800071
虽然与氨原子结合的所示芳族基团可以是杂环,但是它们优选的是碳环;并且虽然它们可以是稠合或未稠合的多环体系,但它们优选的是单6元环。虽然在二-唑的主链中所示的基团是优选的对亚苯基,但是该基团可以被任何不干扰聚合物制备的任何二价有机基团置换,或者根本没有基团。例如,该基团可以是最多12个碳原子的脂肪族基团、亚苄基、亚联苯基、二-亚苯基醚等。
用来制备本发明纤维的聚苯并噁唑和聚苯并噻唑应该具有至少25,优选的是至少100个链节单元。聚合物的制备和这些聚合物的纺丝公开在上述的国际公开WO93/20400中。
“织物紧密系数”和“覆盖系数”是赋予织物织造密度的名字。覆盖系数是与织造几何结构相关的计算值,并且表示被织物纱线覆盖的织物总表面积的百分数。用来计算覆盖系数的公式如下(来自Weaving:Conversion of Yarns to Fabric,Lord and Mohamed,published by Merrow(1982),141-143页):
dw=织物中经纱的宽度
df=织物中纬纱的宽度
pw=经纱的节距(每单位长度的经纱数)
pf=纬纱的节距
c w = d w pw c f = d f pf
Figure A0280816800074
c fab = ( p w - d w ) d f + d w p f p w p f
= ( c f + c w - c f c w )
根据织物织造的种类,即使织物的纱线靠近在一起,但是最大覆盖系数可相当低。由于这一原因,织造织纹的紧密度的更有用的指标称为“织物紧密系数”。织物紧密系数是与最大织造织纹紧密度相比,织物织造紧密度的度量,其是覆盖系数的函数。
例如,对于平纹织纹织物的可能最大覆盖系数为0.75;所以实际覆盖系数为0.45的平纹织纹织物的织物紧密系数为0.60。不同的织物织纹,例如平纹、斜纹或缎纹织纹和它们的变化织纹,能够用于本发明的织物。实际上本发明优选的织纹是斜纹和缎纹织纹和它们的变化织纹,其中包括四经破缎纹织纹,有时是已知的4通丝缎纹织纹,这是由于它们比平纹织纹更加柔软和柔韧并且可以更好地贴合到复杂的曲线和表面上。
用于本发明的纱线必须具有至少10克/分特(11.1克/旦尼尔)的高强度并且对于强度没有上限。强度低于5克/分特,纱线对于有意义的防护不能表现出足够的强度。纱线必须具有至少150克/分特的拉伸模量,因为太低的模量将导致过大的纤维伸长和子弹运动的无效限制。对于拉伸模量没有上限。
本发明的织造织物的单层可提供防弹性的度量,因此提供防护程度的度量,但是在最终的防弹物品中需要具有至少两个松散织造织物层的多个层。正是使用了具有总面密度至少为2至10kg/m2,优选2,5至8kg/m2的多个织物层,其是通过每单位面积的织物层的总重量而测得的,其中至少两个织物层是松散的织造织物层,本发明表现出其突出且出人意料的改进。现已发现,本发明的松散的织造织物层放在一起时,优选的是多层放在一起,当松散的织造织物层彼此固定从而在相邻层之间限制相对运动时,提供了出人意料的有效防弹性。
本发明的防护物品的结构还可与其它的织造或非织造防弹层的纤维网眼织物联合使用,例如单向的,单织造的等。这些层可以由芳族聚酰胺、聚烯烃、聚苯并噁唑、聚苯并噻唑或其它用于防弹的常用的聚合物制造。本发明的织物层可以放置在其它防弹层的下面或上面,或两个其它防弹层之间。如果需要,本发明的织物还能够用基质树脂或粘合剂进行涂覆或浸渍,从而增加织物层的刚性。
测试方法
线密度:纱线或长丝的线密度是通过称重已知长度的纱线或长丝而确定的。“分特”是定义为材料10,000米的重量,以克计。“旦尼尔”是定义为材料9000米的重量,以克计。
在实际情况中,在测试之前,把所测得的纱线或长丝样品的分特、测试条件和样品标识输入计算机;计算机记录线断裂时的负荷-伸长曲线,然后计算特性。
拉伸性能:对于拉伸性能的测试的纱线首先被调湿,然后捻成1.1的捻系数。纱线的捻系数TM定义为:
TM=(捻数/厘米)(分特)-1/2/30.3
  =(捻数/英寸)(旦尼尔)-1/2/73
待测的纱线在25℃、55%相对湿度调湿最少14小时,并且在这些条件下进行拉伸试验。强度(断裂强度)、断裂伸长率和拉伸模量通过断裂试验纱线在Insron试验机(Instron Engineering Corp.,Canton,Mass)上测定。
使用25.4厘米的纱线测量长度和50%应变/分钟的伸长速度,测定强度、伸长率和拉伸模量,如ASTM D2101-1985中所定义的。模量由在1%应变时的应力-应变曲线的斜率计算,并且等于在1%应变(绝对)时的应力(用克表示)乘以100,除以测试纱线的线密度。
单长丝的强度、伸长率和拉伸模量是与纱线的相同方式进行测定;但是长丝不经受加捻和使用2.54cm测量长度。
防弹性能:根据MIL-STD-662e进行多层板的防弹测试,以确定防弹极限(V50),所不同的是子弹的选择有所不同,其如下所述:把待测的板靠着Roma Plasti1ina No.1的背衬材料放置在样品支架上,使板保持拉紧并垂直于测试子弹的路径。子弹是9mm全金属外壳手枪子弹,重124格令和.357大外壳软尖端子弹,重158格令,并且能够以不同的速度从发射子弹的测试用的枪膛射出。对于每个板的第一次射击是为了使估算的子弹速度成为可能的防弹极限(V50)。当第一次射击产生了完全的板穿透时,下一次射击的子弹速度约小15.5米(50英尺)/秒,以获得该板的部分穿透。另一方面,当第一次发射不产生穿透或部分穿透时,下一次发射的速度约大15.2米/秒(50英尺)/秒,以获得完全穿透。在获得一次部分穿透和一次完全穿透之后,随后使用增大或减小约15.2米(50英尺)/秒的速度,直至进行足够的发射,以测定该板的防弹极限(V50)。
通过找出等数量的至少三个最高部分穿透冲击速度和最低完全穿透冲击速度的算数平均值来计算防弹极限(V50),条件时在最高和最低各个冲击速度之间的差值不大于38.1米(125英尺)/秒。
