Description
本発明は、防刃積層体及びこれを用いた防刃具に関する。さらに詳しくは、スーパー繊維を用いた織物と不織布を含む防刃積層体及びこれを用いた防刃具と防刃具用不織布に関する。 The present invention relates to a blade-proof laminate and a blade-proof tool using the same. More specifically, the present invention relates to a blade-proof laminate containing a woven fabric and a non-woven fabric using super fibers, and a blade-proof tool and a non-woven fabric for the blade-proof tool using the same.
従来から防刃衣類、防刃具等の材料として、高強度かつ高弾性繊維を用いた防護具が提案されている。特許文献1には、超高分子量ポリエチレン繊維の平織物と、プロピレン繊維不織布の積層構造が提案されている。特許文献2には、超高分子量ポリエチレン繊維の不織布を防刃性フェルトとして使用することが提案されている。特許文献3には、ポリベンズアゾール繊維の織物を複数枚積層した防刃性材料が提案されている。特許文献4には、織物の表面に炭化ケイ素粒子をコーティングした防護基材を前部に配置し、その後に織物の表面にシリカ粒子をコーティングした防護基材を複数枚配置し、人体側にアラミド繊維のニードルパンチ不織布を配置した防刃チョッキが提案されている。 Conventionally, protective equipment using high-strength and highly elastic fibers has been proposed as a material for blade-proof clothing, blade-proof equipment, and the like. Patent Document 1 proposes a laminated structure of a plain woven fabric of ultra-high molecular weight polyethylene fiber and a propylene fiber non-woven fabric. Patent Document 2 proposes to use a non-woven fabric of ultra-high molecular weight polyethylene fiber as a blade-proof felt. Patent Document 3 proposes a blade-proof material in which a plurality of polybenzazole fiber woven fabrics are laminated. In Patent Document 4, a protective base material coated with silicon carbide particles on the surface of the woven fabric is arranged in the front portion, and then a plurality of protective base materials coated with silica particles are arranged on the surface of the woven fabric, and aramid is arranged on the human body side. A blade-proof waistcoat in which a fiber needle punch non-woven fabric is arranged has been proposed.
以上のように従来から高強度かつ高弾性繊維を含む織物や不織布を用いた防刃具は多く提案されているが、高強度かつ高弾性繊維の特性を生かしたものは提案されていない。すなわち、織物、不織布等の繊維材料は、引っ張り方向の強度や弾性率は高いが、組織的に各繊維が動きやすく、鋭利物体の衝撃を受けると各繊維が移動してしまい、繊維間に鋭利物体が入り込んでしまい、防刃材料が容易に破壊してしまうという問題があった。 As described above, many blade protection tools using woven fabrics and non-woven fabrics containing high-strength and high-elasticity fibers have been proposed, but those utilizing the characteristics of high-strength and high-elasticity fibers have not been proposed. That is, fiber materials such as woven fabrics and non-woven fabrics have high strength and elasticity in the tensile direction, but each fiber is systematically easy to move, and when the impact of a sharp object is received, each fiber moves, resulting in sharpness between the fibers. There is a problem that an object gets in and the blade-proof material is easily destroyed.
本発明は、前記従来の問題を解決するため、鋭利物体の衝撃時には、高強度かつ高弾性繊維の移動は阻止され、前記繊維に切断方向の応力が働くことにより、効率よく衝撃エネルギーを吸収する防刃積層体及びこれを用いた防刃具と防刃具用不織布を提供する。 In order to solve the conventional problem, the present invention efficiently absorbs impact energy by blocking the movement of high-strength and highly elastic fibers at the time of impact of a sharp object and applying stress in the cutting direction to the fibers. Provided are a blade-proof laminate, a blade-proof tool using the same, and a non-woven fabric for the blade-proof tool.
本発明の防刃積層体は、スーパー繊維を含む防刃積層体であって、スーパー繊維糸を経糸と緯糸にした織物に樹脂を一体化した樹脂補強織物と、スーパー繊維を主成分として構成される不織布とを含み、前記不織布は、前記樹脂補強織物の間に入れて交互に積層した交互積層構造であり、前記交互積層構造は、樹脂補強織物と不織布が交互に2組以上積層され、最表面層と最裏面層は樹脂補強織物であり、鋭利物体の衝撃時、前記樹脂補強織物によって両面を挟まれた不織布の構成繊維の移動が阻止され、前記不織布の構成繊維が長さ方向に引っ張られて衝撃エネルギーが吸収されることを特徴とする。
The blade-proof laminate of the present invention is a blade-proof laminate containing super fibers, and is composed of a resin-reinforced woven fabric in which a resin is integrated into a woven fabric in which super fiber yarns are used as warp and weft, and super fibers as a main component. The non-woven fabric is an alternating laminated structure in which two or more sets of the resin-reinforced woven fabric and the non-woven fabric are alternately laminated by being inserted between the resin-reinforced woven fabrics and alternately laminated. The front surface layer and the backmost layer are resin reinforced fabrics, and when a sharp object is impacted, the constituent fibers of the non-woven fabric sandwiched on both sides by the resin reinforced fabric are prevented from moving, and the constituent fibers of the non-woven fabric are pulled in the length direction. It is characterized in that the impact energy is absorbed.
本発明は、前記の防刃積層体を用いた防刃具であって、前記不織布は、前記樹脂補強織物の間に入れて交互に積層した交互積層構造であり、前記交互積層構造は、樹脂補強織物と不織布が交互に2組以上積層され、最表面層と最裏面層は樹脂補強織物の状態であり、前記交互積層構造で防刃具内に収納されていることを特徴とする。
The present invention is a blade-proof tool using the blade-proof laminated body, wherein the non-woven fabric is an alternating laminated structure inserted between the resin-reinforced woven fabrics and alternately laminated, and the alternating laminated structure is resin-reinforced. Two or more sets of woven fabrics and non-woven fabrics are alternately laminated, and the outermost surface layer and the outermost back surface layer are in the state of resin reinforced woven fabric, and are housed in the blade-proof tool in the alternating laminated structure .
本発明の防刃具用不織布は、前記の防刃具に使用するための不織布であって、ポリ(p−フェニレンベンゾビスオキザール)短繊維の熱プレス不織布であることを特徴とする。 The non-woven fabric for a blade-proofing tool of the present invention is a non-woven fabric for use in the above-mentioned blade-proofing tool, and is characterized by being a heat-pressed non-woven fabric of poly (p-phenylene benzobis oxal) short fibers.
本発明の防刃積層体及び防刃具は、樹脂補強織物によって不織布を挟んだサンドイッチ構造であり、鋭利物体の衝撃時、前記樹脂補強織物によって両面を挟まれた不織布の構成繊維の移動が阻止され、前記不織布の構成繊維が長さ方向に引っ張られて衝撃エネルギーが吸収される。不織布の構成繊維はスーパー繊維を主成分としているので、長さ方向に対してはきわめて高い強度と弾性力を有しており、鋭利物体の衝撃力は、スーパー繊維を長さ方向に引っ張るように働くため、きわめて高い防刃性を有する。本発明の防刃具用不織布は、前記の防刃具に使用するための不織布であって、ポリ(p−フェニレンベンゾビスオキザール)(PBO)短繊維の熱プレス不織布であることにより、薄くて人体の動作性を阻害せず、かつ防刃性も高い。 The blade-proof laminate and the blade-proof tool of the present invention have a sandwich structure in which a non-woven fabric is sandwiched between resin-reinforced fabrics, and when a sharp object is impacted, the movement of the constituent fibers of the non-woven fabric sandwiched by the resin-reinforced fabric is prevented. , The constituent fibers of the non-woven fabric are pulled in the length direction to absorb impact energy. Since the constituent fibers of the non-woven fabric are mainly composed of super fibers, they have extremely high strength and elastic force in the length direction, and the impact force of a sharp object pulls the super fibers in the length direction. Because it works, it has extremely high blade resistance. The non-woven fabric for blade protection of the present invention is a non-woven fabric for use in the above-mentioned blade protection, and is thin and human body because it is a heat-pressed non-woven fabric of poly (p-phenylene benzobis oxal) (PBO) short fibers. It does not interfere with the operability of the fabric and has high blade resistance.
本発明の防刃積層体は、スーパー繊維を含み、前記スーパー繊維糸を経糸と緯糸にした織物に樹脂を一体化した樹脂補強織物と、前記スーパー繊維を主成分として構成される不織布とを含み、前記不織布は、前記樹脂補強織物によって両面を挟まれた構造、又は前記樹脂補強織物と前記不織布の交互積層構造である。この交互積層構造は、鋭利物体の衝撃時、前記樹脂補強織物によって両面を挟まれた不織布の構成繊維の移動が阻止され、前記不織布の構成繊維が長さ方向に引っ張られて衝撃エネルギーが吸収される。不織布の構成繊維はスーパー繊維を主成分としているので、長さ方向に対してはきわめて高い強度と弾性力を有しており、鋭利物体の衝撃力は、スーパー繊維を長さ方向に引っ張るように働くため、きわめて高い防刃性を有する。ここで主成分とは、不織布を100質量%としたとき、スーパー繊維が50質量%以上をいう。 The blade-proof laminate of the present invention contains super fibers, and includes a resin reinforced woven fabric in which a resin is integrated into a woven fabric in which the super fiber threads are used as warp and weft, and a non-woven fabric composed mainly of the super fibers. The non-woven fabric has a structure in which both sides are sandwiched between the resin-reinforced fabrics, or an alternating laminated structure of the resin-reinforced fabric and the non-woven fabric. In this alternating laminated structure, when a sharp object is impacted, the constituent fibers of the non-woven fabric sandwiched on both sides by the resin reinforced fabric are prevented from moving, and the constituent fibers of the non-woven fabric are pulled in the length direction to absorb impact energy. To. Since the constituent fibers of the non-woven fabric are mainly composed of super fibers, they have extremely high strength and elastic force in the length direction, and the impact force of a sharp object pulls the super fibers in the length direction. Because it works, it has extremely high blade resistance. Here, the main component means 50% by mass or more of super fibers when the non-woven fabric is 100% by mass.
交互積層構造は、樹脂補強織物と不織布が交互に2組以上積層され、最表面層と最裏面層は樹脂補強織物であるのが好ましい。最表面と最裏面に樹脂補強織物を配置すると、その間に挟まれた不織布の構成繊維の移動が阻止され、前記不織布の構成繊維が長さ方向に引っ張られて衝撃エネルギーが吸収される。 In the alternating laminated structure, it is preferable that two or more sets of resin reinforced fabrics and non-woven fabrics are alternately laminated, and the outermost surface layer and the outermost back surface layer are resin reinforced fabrics. When the resin reinforced woven fabric is arranged on the outermost surface and the innermost back surface, the movement of the constituent fibers of the nonwoven fabric sandwiched between them is prevented, and the constituent fibers of the nonwoven fabric are pulled in the length direction to absorb the impact energy.
スーパー繊維は、強度:18cN/dtex以上、弾性率:380cN/dtex以上の高強度かつ高弾性繊維糸であるのが好ましい。一例としてスーパー繊維糸は、アラミド繊維、ポリアリレート繊維、ポリ(p−フェニレンベンゾビスオキザール)(PBO)繊維、ポリ(p−フェニレンベンゾビスチアゾール)(PBZT)繊維、ポリエチレン繊維、ポリエーテルエーテルケトン繊維及びポリビニルアルコール繊維から選ばれる少なくとも一つの繊維糸である。 The super fiber is preferably a high-strength and highly elastic fiber yarn having a strength of 18 cN / dtex or more and an elastic modulus of 380 cN / dtex or more. As an example, super fiber yarns include aramid fibers, polyarylate fibers, poly (p-phenylene benzobis oxal) (PBO) fibers, poly (p-phenylene benzobisthiazole) (PBZT) fibers, polyethylene fibers, and polyether ether ketones. At least one fiber yarn selected from fibers and polyvinyl alcohol fibers.
不織布は、スーパー繊維が50〜100質量%であり、他の繊維が0〜50質量%であるのが好ましい。すなわち、スーパー繊維が100質量%であってもよいし、他の繊維が0質量%を超え50質量%以下混紡してもよい。他の繊維は、普通繊維及び熱融着繊維から選ばれる少なくとも一つが好ましい。ここで普通繊維とは、ポリエステル、ナイロン、アクリル、ウール、コットン、麻、レーヨン等の衣料用で使用されている繊維をいう。熱融着繊維を使用する場合は、混紡品100質量%としたとき、熱融着繊維5〜20質量%が好ましい。 The non-woven fabric preferably contains 50 to 100% by mass of super fibers and 0 to 50% by mass of other fibers. That is, the super fiber may be 100% by mass, or the other fibers may be blended in an amount of more than 0% by mass and 50% by mass or less. The other fiber is preferably at least one selected from ordinary fibers and heat-sealed fibers. Here, the ordinary fiber means a fiber used for clothing such as polyester, nylon, acrylic, wool, cotton, hemp, and rayon. When heat-sealed fibers are used, 5 to 20% by mass of heat-sealed fibers are preferable when the blended product is 100% by mass.
不織布は、厚さ2mm以下、質量80〜300g/m2が薄くて動作を阻害せず、かつ防刃性を発揮することから好ましい。不織布はニードルパンチ不織布、水流交絡不織布、スティッチ交絡不織布、或いはこれらの不織布を加熱プレス圧縮した不織布など任意のものを使用できる。この中でも、薄くて人体の動作性を阻害せず、かつ防刃性も高いポリ(p−フェニレンベンゾビスオキザール)(PBO)短繊維の熱プレス不織布が好ましい。 The non-woven fabric is preferable because it has a thickness of 2 mm or less and a mass of 80 to 300 g / m 2 and is thin, does not hinder the operation, and exhibits blade resistance. As the non-woven fabric, any non-woven fabric such as needle punched non-woven fabric, water flow entangled non-woven fabric, stitch entangled non-woven fabric, or non-woven fabric obtained by heating and pressing these non-woven fabrics can be used. Among these, a heat-pressed non-woven fabric of poly (p-phenylene benzobis oxal) (PBO) short fibers, which is thin, does not hinder the operability of the human body, and has high blade resistance, is preferable.
前記樹脂補強織物は、織物に熱可塑性樹脂フィルムをラミネートしたラミネート織物及び織物に樹脂を含浸させたプリブレグ織物から選ばれる少なくとも一つであるのが好ましい。プリブレグ織物は樹脂を硬化させておくのが好ましい。このような樹脂補強織物は、鋭利物体が当たっても、織物を構成する経糸及び緯糸が簡単には移動せず、高い防刃性を有する。このような樹脂補強織物は市販されており、例えばラミネート加工したpアラミド織物として、TENCATE ADVANCED ARMOR USA,INC社製、商品名"TenCate Pro−Tector"がある。 The resin reinforced woven fabric is preferably at least one selected from a laminated woven fabric in which a thermoplastic resin film is laminated on the woven fabric and a Libreg woven fabric in which the woven fabric is impregnated with a resin. It is preferable that the resin of the Libreg woven fabric is cured. Such a resin-reinforced woven fabric has high blade resistance because the warp and weft that make up the woven fabric do not easily move even when it is hit by a sharp object. Such resin-reinforced woven fabrics are commercially available. For example, as a laminated p-aramid woven fabric, there is a trade name "TenCate Pro-Tector" manufactured by TENCATE ADVANCED ARMOR USA, INC.
前記樹脂補強織物の表面には無機物粉体がバインダー樹脂とともにコーティングされていてもよい。表面に無機物粉体が固定されていると、高い防刃性を有する。
The surface of the resin reinforced fabric may be coated with an inorganic powder together with a binder resin. When the inorganic powder is fixed on the surface, it has high blade resistance.
本発明の防刃具は、不織布は樹脂補強織物によって両面を挟まれた状態又は樹脂補強織物と不織布の交互積層状態で防刃具内に収納されている。前記防刃積層体を一つの袋内に収納した状態で防護服の収納部などに入れることにより、簡単に取り付けることができる。 In the blade-proof tool of the present invention, the non-woven fabric is stored in the blade-proof tool in a state where both sides are sandwiched between resin-reinforced woven fabrics or in a state in which resin-reinforced woven fabrics and non-woven fabrics are alternately laminated. The blade-proof laminate can be easily attached by putting it in a storage portion of protective clothing or the like in a state of being stored in one bag.
以下図面を用いて説明する。以下の図面において、同一符号は同一物を示す。図1は本発明の一実施形態の防刃積層体1の模式的断面図である。この防刃積層体1は、スーパー繊維を主成分として構成される不織布2a−2dと、スーパー繊維糸を経糸と緯糸にした織物に樹脂を一体化した樹脂補強織物3a−3eで構成され、不織布2a−2dは樹脂補強織物3a−3eによって両面を挟まれた構造、又は樹脂補強織物3a−3eと不織布2a−2dの交互積層構造である。これにより、鋭利物体の衝撃時、樹脂補強織物3a−3eによって両面を挟まれた不織布2a−2dの構成繊維の移動が阻止され、不織布2a−2dの構成繊維が長さ方向に引っ張られて衝撃エネルギーが吸収される。不織布2a−2dと樹脂補強織物3a−3eは、一体として取り扱うため、袋に入れておいてもよい。
This will be described below with reference to the drawings. In the drawings below, the same reference numerals indicate the same thing. FIG. 1 is a schematic cross-sectional view of the blade-proof laminated body 1 according to the embodiment of the present invention. The blade-proof laminate 1 is composed of a non-woven fabric 2a-2d composed mainly of super fibers and a resin reinforced woven fabric 3a-3e in which a resin is integrated with a woven fabric in which super fiber threads are used as warp and weft threads. 2a-2d is a structure in which both sides are sandwiched by a resin reinforced fabric 3a-3e, or an alternating laminated structure of a resin reinforced fabric 3a-3e and a non-woven fabric 2a-2d. As a result, when a sharp object is impacted, the constituent fibers of the nonwoven fabric 2a-2d sandwiched by the resin reinforced fabric 3a-3e are prevented from moving, and the constituent fibers of the nonwoven fabric 2a-2d are pulled in the length direction to impact. Energy is absorbed. Since the non-woven fabric 2a-2d and the resin reinforced fabric 3a-3e are handled as one, they may be put in a bag .
図2は本発明の別の実施形態の防刃積層体の模式的断面図である。この防刃積層体は、図1に示す防刃積層体1の表面に、樹脂補強織物4aの表面に無機物粉体がバインダー樹脂とともにコーティングされている無機物粉体コーティング層5aを4枚積層した例である。ここで、樹脂補強織物4aと無機物粉体コーティング層5aは、先鋭刃物破壊層と呼ぶ。この先鋭刃物破壊層6a−6dからなる積層体7を防刃積層体1の表面に積層する。このようにすると先鋭刃物が当たったとき、刃物先端を破壊し、防刃積層体の内部に刃物が入りにくくなる。 FIG. 2 is a schematic cross-sectional view of a blade-proof laminate according to another embodiment of the present invention. This blade-proof laminate is an example in which four inorganic powder coating layers 5a in which inorganic powder is coated together with a binder resin on the surface of the resin reinforced fabric 4a are laminated on the surface of the blade-proof laminate 1 shown in FIG. Is. Here, the resin reinforced fabric 4a and the inorganic powder coating layer 5a are referred to as a sharp edge blade breaking layer. The laminated body 7 made of the sharp blade breaking layers 6a-6d is laminated on the surface of the blade-proof laminated body 1. In this way, when the sharp blade hits, the tip of the blade is destroyed and it becomes difficult for the blade to enter the inside of the blade-proof laminate.
図3は本発明の一実施形態の防刃具8の模式的断面図である。この防刃具8は、一例として防刃ベストとしたもので、胴部9に前記防刃積層体1と、先鋭刃物破壊層からなる積層体7を重ねて収納している。前記防刃積層体1と先鋭刃物破壊層からなる積層体7は一つの袋内に収納した状態で防護服の収納部などに収納してもよい。 FIG. 3 is a schematic cross-sectional view of the blade protection tool 8 according to the embodiment of the present invention. The blade-proof tool 8 is a blade-proof vest as an example, and the blade-proof laminate 1 and a laminate 7 made of a sharp-edged blade breaking layer are stacked and stored in a body portion 9. The laminated body 7 composed of the blade-proof laminated body 1 and the sharp-edged blade breaking layer may be stored in a protective clothing storage portion or the like in a state of being stored in one bag.
以下、実施例を用いて本発明をさらに具体的に説明する。なお、本発明は下記の実施例に限定されるものではない。
<刃物貫通試験方法>
米国司法省基準NIJ Standard-0115.00試験(刃物貫通試験)に従って測定した。先端にアイスピックを取り付けた総重量2.22kgの重錘を準備し、ガイドを介して垂直に落下する装置を作製した。装置にはレーザー変位計を取り付けており、重錘の変位が測定され、加速度により、突刺し抵抗が算出される。アイスピックはNIJ115に記載されているものを使用した。試料はNIJ115に記載されている裏材(4層のネオプレンゴムスポンジ(厚み5.8mm)、1層のクローズドセルのポリエチレンフォーム(厚み31mm、密度33kg/m3)、2層の天然ゴム(厚み6.4mm))の上に置き、重錘は運動エネルギーが24±0.5Jになるよう速度をコントロールし、アイスピックで試料を垂直に突刺した。貫通するまでに吸収するエネルギーをレーザー変位計から算出し、吸収エネルギーとして測定した。この値が高い程、防刃性が高いということになる。また、アイスピックが試料の底から突き抜けた長さを突刺し長さとして測定した。この値が小さいほど防刃性が良いことになる。
<剛軟度>
剛軟度の測定はJIS L1913に規定されている曲げ剛性試験のガーレ法を用いた。
Hereinafter, the present invention will be described in more detail with reference to Examples. The present invention is not limited to the following examples.
<Knife penetration test method>
Measured according to the US Department of Justice standard NIJ Standard-0115.00 test (cutlery penetration test). A weight with a total weight of 2.22 kg with an ice pick attached to the tip was prepared, and a device for vertically dropping via a guide was manufactured. A laser displacement meter is attached to the device, the displacement of the weight is measured, and the piercing resistance is calculated by the acceleration. The ice pick described in NIJ115 was used. The sample is the backing material described in NIJ115 (4 layers of neoprene rubber sponge (thickness 5.8 mm), 1 layer of closed cell polyethylene foam (thickness 31 mm, density 33 kg / m 3 )), 2 layers of natural rubber (thickness). The sample was placed on 6.4 mm)), the speed of the weight was controlled so that the kinetic energy was 24 ± 0.5 J, and the sample was pierced vertically with an ice pick. The energy absorbed before penetrating was calculated from a laser displacement meter and measured as absorbed energy. The higher this value, the higher the blade resistance. In addition, the length of the ice pick penetrating from the bottom of the sample was measured as the piercing length. The smaller this value is, the better the blade resistance is.
