Abstract

Provided is a stab-proof laminate 1 that includes super fibers, the stab-proof laminate comprising: resin-reinforced fabrics 3a-3e obtained by incorporating resin into a fabric in which super fibers are used for warp and weft; and nonwoven fabrics 2a-2d formed chiefly of the super fibers. The nonwoven fabrics 2a-2d are structured so as to be sandwiched by the resin-reinforced fabrics 3a-3e from both surfaces. When an impact by a sharp object occurs, the movement of constituent fibers of the nonwoven fabric 2a-2d sandwiched by the resin-reinforced fabrics 3a-3e from both surfaces is inhibited, causing the constituent fibers of the nonwoven fabrics 2a-2d to be pulled in the longitudinal direction, thereby absorbing impact energy. The stab-proof implement according to the present invention is configured to accommodate the nonwoven fabrics in a state of being sandwiched by the resin-reinforced fabrics from both surfaces, or in a state in which the nonwoven fabrics and the resin-reinforced fabrics are stacked alternately. This configuration inhibits high-strength, high-modulus fibers from moving upon impact by a sharp object, and causes a stabbing-direction stress to act on the fiber, and thereby enables efficient absorption of impact energy.

　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, although many cutting tools using a woven fabric or non-woven fabric containing high strength and high elasticity fiber have been conventionally proposed, those utilizing the characteristics of high strength and high elasticity fiber have not been proposed. That is, although fiber materials such as woven fabrics and non-woven fabrics have high strength and elastic modulus in the tensile direction, each fiber tends to move systematically, and each fiber moves when it receives an impact from a sharp object, causing sharpening between fibers There is a problem that the object gets in and the blade material is easily broken.
　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 above-mentioned conventional problems, the present invention prevents the movement of high strength and high elasticity fibers at the time of impact of a sharp object, and efficiently absorbs impact energy by exerting stress in the cutting direction on the fibers. A blade-proof laminate, a blade-proof tool using the same, and a nonwoven fabric for blade-proof tool.

The non-woven fabric has a structure in which both sides are sandwiched by the resin-reinforced fabric, and when impact of a sharp object, the movement of constituent fibers of the non-woven fabric sandwiched by both sides is inhibited by the resin-reinforced fabric. Is a blade-proof laminate in which impact energy is absorbed by being pulled in the length direction.
　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、前記樹脂補強織物によって両面を挟まれた状態、又は前記樹脂補強織物と前記不織布の交互積層状態で防刃具内に収納されている。 The present invention is a blade-proof tool using the above-mentioned blade-proof laminate, wherein the non-woven fabric is in a state in which both surfaces are sandwiched by the resin-reinforced fabric, or alternatively It is housed inside.
　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 nonwoven fabric for blade protection of the present invention is a nonwoven fabric for use in the above-mentioned blade protection and is characterized in that it is a heat-pressed nonwoven 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 according to the present invention have a sandwich structure in which the non-woven fabric is sandwiched by the resin reinforced fabric, and the movement of the non-woven fabric sandwiched on both sides by the resin reinforced fabric is blocked The constituent fibers of the non-woven fabric are pulled in the longitudinal 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 elasticity in the length direction, and the impact force of the sharp object is to pull the super fibers in the length direction. Because it works, it has extremely high blade resistance. The nonwoven fabric for cutting tool according to the present invention is a non-woven fabric for use in the above-described cutting tool, and is a heat-pressed nonwoven fabric of poly (p-phenylene benzobis oxal) (PBO) staple fiber, so that it is thin and human body Does not impede the operation of the

The non-woven fabric has a structure in which both surfaces are sandwiched by the resin-reinforced woven fabric, or an alternate laminated structure of the resin-reinforced woven fabric and the non-woven fabric. In this alternate layered structure, when impacted by a sharp object, movement of constituent fibers of the non-woven fabric sandwiched on both sides by the resin reinforced fabric is inhibited, and 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 elasticity in the length direction, and the impact force of the sharp object is to pull the super fibers in the length direction. Because it works, it has extremely high blade resistance. Here, when the non-woven fabric is 100% by mass, the main component means 50% by mass or more of the super fiber.
　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 alternate lamination structure, two or more sets of resin-reinforced woven fabric and non-woven fabric are alternately laminated, and the outermost surface layer and the outermost surface layer are preferably resin-reinforced woven fabric. When the resin reinforced fabric is disposed on the outermost surface and the outermost surface, the movement of the constituent fibers of the non-woven fabric sandwiched between them is prevented, and the constituent fibers of the non-woven fabric are pulled in the length direction to absorb impact energy.

As an example, super fiber yarn is aramid fiber, polyarylate fiber, poly (p-phenylene benzo bis oxal) (PBO) fiber, poly (p phenylene benzo bis thiazole) (PBZT) fiber, polyethylene fiber, polyether ether ketone It is 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 superfibers and 0 to 50% by mass of other fibers. That is, 100% by mass of the super fiber may be mixed, and more than 0% by mass and 50% by mass or less of other fibers may be blended. The other fibers are preferably at least one selected from ordinary fibers and heat fusion fibers. The term "ordinary fibers" as used herein refers to fibers used for clothing such as polyester, nylon, acrylic, wool, cotton, hemp, rayon and the like. When heat fusible fibers are used, the heat fusible fibers are preferably 5 to 20% by mass, based on 100% by mass of the blended product.
　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 weight of 80 to 300 g / m 2, which is thin and does not inhibit the operation, and exhibits blade-proof properties. The nonwoven fabric may be any of a needle punched nonwoven fabric, a water-entangled nonwoven fabric, a stitch-entangled nonwoven fabric, or a nonwoven fabric obtained by heat-pressing the nonwoven fabric of these nonwoven fabrics. Among these, a heat-pressed nonwoven fabric of a thin poly (p-phenylene benzo bis oxal) (PBO) short fiber which does not inhibit the operability of the human body and has a 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 fabric is preferably at least one selected from a laminated fabric obtained by laminating a thermoplastic resin film on a fabric and a pre-breg fabric obtained by impregnating a fabric on a fabric. Prebreg woven fabric is preferably cured of resin. Such a resin-reinforced fabric has high blade resistance, since the warp yarns and wefts constituting the fabric do not move easily even when a sharp object strikes. Such a resin reinforced fabric is commercially available, for example, as a laminated p-aramid fabric, there is TENCATE ADVANCED ARMOR USA, manufactured by INC, trade name "TenCate Pro-Tector".
　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。 An inorganic powder may be coated with a binder resin on the surface of the resin reinforced fabric. When inorganic powder is fixed to the surface, it has high blade-proof properties.

The blade-proof tool 8 is, for example, a blade-proof vest, and the body 9 is made up of the blade-proof laminate 1 and the laminate 7 formed of a sharp blade-breaking layer. The laminate 7 including the blade-proof laminate 1 and the sharp-edged blade-breaking layer may be stored in a storage section of protective clothing or the like in a state of being stored in one bag.
