　本発明は、防護素材に関する。 The present invention relates to a protective material.
　従来より、チェーンソーや刈払い機などの刃物を使った作業に従事する作業者が、誤って作業中の刃物を体に接触させてしまった場合に備えて、強度の高い繊維を使った防護層を備えた衣服や軍手、防具等が提案されている。 Conventionally, a protective layer using high-strength fibers in case a worker engaged in work using a knife such as a chainsaw or a brush cutter accidentally touches the knife during work with the body.

特開２０１８－５２７４８２号公報JP-A-2018-527482
　上述した技術は、チェーンソー作業中にチェーンソーが体に当たった場合に、衣服中に含まれる高強度繊維層がチェーンソーの刃に絡まることでチェーンソーの刃の回転を止めることができるものである。しかしながら、従来のチェーンソーパンツにおいては、高強度繊維からなる保護層を複数積層することによって保護能力を担保しているために、刃が接触した瞬間にまず一番表面側の保護層の繊維が刃に絡まるが、さらに一つ内側の層の繊維が外に出ていくのは表面の層の繊維が外に引っ張り出された後になってしまう。したがって、瞬間的に引っ張り出されて刃に絡まることのできる繊維の量には限りがあり、刃の回転を止めるのに十分な量の繊維が引っ張り出されるまでにタイムラグがあった。 The above-mentioned technique can stop the rotation of the chainsaw blade by entwining the high-strength fiber layer contained in the clothes with the chainsaw blade when the chainsaw hits the body during the chainsaw work. However, in the conventional chainsaw pants, since the protective ability is secured by laminating a plurality of protective layers made of high-strength fibers, the fibers of the protective layer on the outermost surface side are the blades at the moment when the blades come into contact with each other. However, the fibers in the inner layer go out only after the fibers in the surface layer are pulled out. Therefore, the amount of fibers that can be instantaneously pulled out and entangled with the blade is limited, and there is a time lag before a sufficient amount of fibers are pulled out to stop the rotation of the blade.
　そこで、本発明は、従来よりも保護効果の高い防護素材を提供することを一つの目的とする。 Therefore, one object of the present invention is to provide a protective material having a higher protective effect than the conventional one.
　本発明によれば、地組織と、前記地組織に係止されたループ状のパイル部を有することを特徴とする、切創防止用防護素材が得られる。 According to the present invention, a protective material for preventing cuts can be obtained, which is characterized by having a ground structure and a loop-shaped pile portion locked to the ground structure.
　本発明によれば、瞬時に従来よりも多くの量の繊維が飛び出すことができるので、刃が体に当たったときの怪我を防止することができる。 According to the present invention, since a larger amount of fibers can be instantly popped out than before, it is possible to prevent injury when the blade hits the body.

＜実施の形態の詳細＞
　以下、本発明の実施の形態について、図面を参照しながら説明する。 <Details of the embodiment>
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
＜概要＞
　本発明の防護素材１は、パイル部２を有することを特徴とする。 <Overview>
The protective material 1 of the present invention is characterized by having a pile portion 2.
　パイル部２とは、図１に図示するように、基布上に繊維が立設したいわゆるパイル構造を織り出した構造を指す。本発明においてパイルはループ状であることが好ましい。パイル部２を有することによって、繊維一本当たりの長さを長くすることができる。繊維一本当たりの長さが長くなることによって、瞬間的に刃に絡まる繊維の量を多くすることができる。 As shown in FIG. 1, the pile portion 2 refers to a structure in which a so-called pile structure in which fibers are erected on a base cloth is woven. In the present invention, the pile is preferably loop-shaped. By having the pile portion 2, the length per fiber can be increased. By increasing the length of each fiber, the amount of fibers entwined with the blade can be increased instantaneously.
　本発明の防護素材１は、図１に図示するように、地組織３と、地組織３に係止されたパイル糸からなるパイル部２とを含む。地組織３は、平織、綾織など既知の織物を用いることができる。パイル糸は、地組織３のタテ糸又はヨコ糸に織り込まれるようにして係止される。図１においては、地組織３を構成する繊維について、１条間隔でパイル糸が織り込まれたものを例示しているが、パイル糸を織り込む間隔や密度はこれに限られない。例えば、図２に示すように繊維２条に一回パイル糸を織り込むようにしてもよく、本発明の効果が得られる範囲で適宜決定することができる。 As shown in FIG. 1, the protective material 1 of the present invention includes a ground structure 3 and a pile portion 2 made of pile yarn locked to the ground structure 3. As the ground structure 3, known woven fabrics such as plain weave and twill weave can be used. The pile yarn is locked so as to be woven into the warp yarn or the weft yarn of the ground structure 3. In FIG. 1, the fibers constituting the ground structure 3 are illustrated in which pile yarns are woven at one-row intervals, but the intervals and densities at which the pile yarns are woven are not limited to this. For example, as shown in FIG. 2, the pile yarn may be woven into the two fibers once, and the pile yarn may be appropriately determined within the range in which the effect of the present invention can be obtained.
　また、図３に図示するように、防護素材１は、第一の地組織３と、第二の地組織４と、第一の地組織３と第二の地組織４の間に配置され、第一地組織３及び第二地組織４のそれぞれに係止されたパイル部２を含んでもよい。当該構成によれば、繊維のボリュームが大きくなるため、より切創防止効果が高くなるとともに、パイル部２のループ部分が第二地組織４に係止されて固定されるので、使用時に偏ることなく均等に保持され、防護性能が均質となる。 Further, as shown in FIG. 3, the protective material 1 is arranged between the first ground organization 3, the second ground organization 4, the first ground organization 3 and the second ground organization 4. A pile portion 2 locked to each of the first ground structure 3 and the second ground structure 4 may be included. According to this configuration, the volume of the fiber is increased, so that the cut prevention effect is further enhanced, and the loop portion of the pile portion 2 is locked and fixed to the second tissue 4 so that it is biased during use. It is held evenly and the protection performance becomes uniform.
　また、図４、５に示すように、地組織３、４及びパイル部２のいずれかは、端部に沿って耳部を有することが好ましい。耳部とは、布の端部において形成される折り返し部である（図４中、パイル部２の場合は耳部２０、地組織３、４の場合は耳部３０）。図５は、地組織３、４のみを取り出した図（パイル部２を省略）である。「端部に沿って」、とは、布の縦若しくは横の辺の少なくとも一部に沿って耳部が形成される状態を指す。耳部２０、３０を形成することによって、端部において繊維が途切れることなく、１本当たりの長さがより長い繊維を織り込むことができる。地組織３、４及びパイル部２のいずれもが端部に耳部２０、３０を備えていることが好ましいが、パイル部２又は地組織３、４のいずれかのみが耳部を有していてもよい。 Further, as shown in FIGS. 4 and 5, it is preferable that any of the ground structures 3, 4 and the pile portion 2 has an ear portion along the end portion. The selvage portion is a folded portion formed at the end portion of the cloth (in FIG. 4, the selvage portion 20 in the case of the pile portion 2 and the selvage portion 30 in the case of the ground tissue 3 and 4). FIG. 5 is a diagram in which only the ground structures 3 and 4 are taken out (pile portion 2 is omitted). "Along the edges" refers to the condition in which the ears are formed along at least a portion of the vertical or horizontal sides of the fabric. By forming the ears 20 and 30, it is possible to weave fibers having a longer length per fiber without breaking the fibers at the ends. It is preferable that both the ground structures 3 and 4 and the pile portion 2 have the ears 20 and 30 at the ends, but only the pile portion 2 or the ground structures 3 and 4 have the ears. You may.
　なお、図４、５に示すように、地組織３、４及びパイル部２に耳部を形成して１本の繊維長を長くした場合、防護被服の意匠・形状によっては、回転刃が当たって瞬時にすべての繊維が途切れることなく吐出されることにより、着用者の外皮（皮膚）を繊維が包み込み圧迫（挟み込む）することが考えられる。その場合には、適当な繊維長になるように一定長で端部（耳部）の繊維を切断することで着用者の皮膚を包み込み圧迫を防止することもできる。 As shown in FIGS. 4 and 5, when the ears are formed in the ground structures 3, 4 and the pile portion 2 to lengthen one fiber, the rotary blade hits depending on the design and shape of the protective clothing. It is conceivable that the fibers wrap around the exodermis (skin) of the wearer and press (sandwich) the outer skin (skin) of the wearer by instantaneously discharging all the fibers without interruption. In that case, it is possible to wrap the wearer's skin and prevent compression by cutting the fibers at the end (ear) at a constant length so as to have an appropriate fiber length.
地組織３、４及びパイル部２は、綿、麻、化学繊維等いずれの素材からなってもよい。化学繊維としてポリエステル、ナイロン、アクリル等を用いることができる。また、地組織３、４及びパイル部２の少なくともいずれかが高強度繊維含有繊維からなることが望ましい。さらに好ましくは、地組織３、４及びパイル部２の双方が高強度繊維含有繊維からなることとしてもよい。この場合、地組織３、４とパイル部２とは、同種の高強度繊維含有繊維を用いてもよいし、異なる種類の高強度繊維含有繊維からなってもよい。また、パイル部２のみを高強度繊維含有繊維から構成することもできる。その場合、地組織を構成する繊維は、適宜他の素材を用いることとしてもよい。高強度繊維含有繊維は、高強度繊維を１％以上含有する繊維であり、好ましくは５％以上、より好ましくは１０％以上、さらに好ましくは３０％以上含有する。 The ground structures 3 and 4 and the pile portion 2 may be made of any material such as cotton, hemp, and chemical fiber. Polyester, nylon, acrylic and the like can be used as the chemical fiber. Further, it is desirable that at least one of the ground structures 3, 4 and the pile portion 2 is made of high-strength fiber-containing fibers. More preferably, both the ground structures 3, 4 and the pile portion 2 may be made of high-strength fiber-containing fibers. In this case, the ground structures 3 and 4 and the pile portion 2 may be made of the same type of high-strength fiber-containing fibers or may be made of different types of high-strength fiber-containing fibers. Further, only the pile portion 2 may be composed of high-strength fiber-containing fibers. In that case, other materials may be used as appropriate for the fibers constituting the ground structure. The high-strength fiber-containing fiber is a fiber containing 1% or more of high-strength fiber, preferably 5% or more, more preferably 10% or more, still more preferably 30% or more.
　本発明において高強度繊維とは、通常切創防止具に用いられるものを用いることができ、強靭性と高弾性率を備えたものであると、切創防止性が高く好ましい。例えば、アラミド繊維やポリアリレート繊維、ポリパラフェニレンベンゾビスオキサゾール繊維等を用いることができる。中でも、アラミド繊維としてケブラー（登録商標）を用いることが好ましい。また、繊維はモノフィラメントでもマルチフィラメントでもよいが、強度の観点から適度な径を有するマルチフィラメントが好ましい。 In the present invention, as the high-strength fiber, those usually used for cut prevention tools can be used, and those having toughness and high elastic modulus are preferable because of high cut prevention property. For example, aramid fiber, polyarylate fiber, polyparaphenylene benzobisoxazole fiber and the like can be used. Above all, it is preferable to use Kevlar (registered trademark) as the aramid fiber. The fiber may be monofilament or multifilament, but a multifilament having an appropriate diameter is preferable from the viewpoint of strength.
　地組織３、４から突出したパイル長は、特に制限はないが、１～２０ｍｍであると好ましく、３～５ｍｍであることがより好ましい。パイル長が当該範囲の下限値以上であると、一本当たりの繊維長が長くなり、回転刃が当たった際により多量の繊維が絡まることができ、切創防止効果が高まる。また、パイル長が当該範囲の上限値以下であると、繊維を衣服などに用いた際に嵩張りすぎず、適度な通気性、動きやすさを維持することができる。 The pile length protruding from the ground structures 3 and 4 is not particularly limited, but is preferably 1 to 20 mm, more preferably 3 to 5 mm. When the pile length is equal to or more than the lower limit of the range, the fiber length per fiber becomes long, and a larger amount of fibers can be entangled when the rotary blade hits, and the cut prevention effect is enhanced. Further, when the pile length is not more than the upper limit value of the above range, the fibers are not too bulky when used for clothes and the like, and appropriate air permeability and ease of movement can be maintained.
　また、パイル部２を構成する繊維の一本当たりの平均長さは、防護素材１の幅に対して１．５倍～２．５倍程度となるようにすることができる。例えばチェーンソーパンツに用いた場合、太腿部分の布幅が例えば３０ｃｍである場合は、繊維の一本当たりの長さは平均して約４５ｃｍ～７５ｃｍ程度となるようにパイル部２を構成することができる。 Further, the average length of each fiber constituting the pile portion 2 can be set to be about 1.5 to 2.5 times the width of the protective material 1. For example, when used for chainsaw pants, when the cloth width of the thigh is, for example, 30 cm, the pile portion 2 is configured so that the length per fiber is about 45 cm to 75 cm on average. Can be done.
　次に、本発明の防護素材１を使用した切創防止具について説明する。 Next, a cut prevention device using the protective material 1 of the present invention will be described.
　本発明の防護素材１は、刃物や金属を扱う作業時に用いる切創防止具に使用される。切創防止具としては、衣服、手袋、腕カバー、チャップス、脚絆、靴、シューズカバー、帽子、等に用いることができる。特に、チェーンソーや刈払い機などの回転刃を使った作業時に着用する衣服等に用いると、パイル部２及び地組織２、３を構成する繊維が回転刃に絡まって被害を防止することができるため効果を発揮する。本発明の防護素材１は、切創防止具の一部のみに使用されてもよい。例えばチェーンソーパンツに用いられる場合、前面の腿部分、膝部分等の保護領域にのみ本発明の防護素材１を使用することができる。 The protective material 1 of the present invention is used as a cut prevention tool used when working with a knife or metal. As the cut prevention tool, it can be used for clothes, gloves, arm covers, chaps, leg ties, shoes, shoe covers, hats, and the like. In particular, when it is used for clothes worn when working with a rotary blade such as a chainsaw or a brush cutter, the fibers constituting the pile portion 2 and the ground structures 2 and 3 can be entangled with the rotary blade to prevent damage. Therefore, it is effective. The protective material 1 of the present invention may be used only for a part of the cut prevention tool. For example, when used for chainsaw pants, the protective material 1 of the present invention can be used only in the protective area such as the front thigh portion and the knee portion.
　切創防止具に使用される場合は、図６に示すように、本発明の防護素材１の他に、内面側及び外表面側に追加の層を設けることができる。追加層の素材、厚み、層数は切創防止具によって適切なものを選択することができる。例えば、チェーンソーパンツなどの衣服に用いられる場合、脚の前面部分を、最も肌に近い側の内層７と、本発明の防護素材１を含む防護層６と、外層５とを順に積層したもので構成することができる。内層７は、通気性のよいメッシュ生地を用いることが好ましい。メッシュ生地としては、既知の繊維素材を用いることができ、例えばポリエステル等を使用する。また、外層５は、強度がありかつ撥水性のある生地が好ましい。外層５としては、既知の繊維素材を用いることができ、例えばナイロン、ポリウレタン、綿等の素材を含む生地を用いることができる。防護層６は、本発明の防護素材１を一層以上含むことができるが、一層のみから構成することもできる。本発明の防護素材１によれば、一層で十分な量の繊維を含むので、防護素材１を複数積層する必要がない。 When used as a cut prevention tool, as shown in FIG. 6, additional layers can be provided on the inner surface side and the outer surface side in addition to the protective material 1 of the present invention. The material, thickness, and number of layers of the additional layer can be selected appropriately depending on the cut prevention tool. For example, when used for clothing such as chainsaw pants, the front portion of the leg is formed by laminating the inner layer 7 on the side closest to the skin, the protective layer 6 containing the protective material 1 of the present invention, and the outer layer 5 in this order. Can be configured. For the inner layer 7, it is preferable to use a mesh fabric having good breathability. As the mesh fabric, a known fiber material can be used, and for example, polyester or the like is used. Further, the outer layer 5 is preferably a strong and water-repellent fabric. As the outer layer 5, a known fiber material can be used, and for example, a fabric containing a material such as nylon, polyurethane, or cotton can be used. The protective layer 6 may contain one or more layers of the protective material 1 of the present invention, but may be composed of only one layer. According to the protective material 1 of the present invention, since one layer contains a sufficient amount of fibers, it is not necessary to stack a plurality of protective materials 1.
　図１に図示した防護素材１を切創防止具として用いる場合は、地組織３の面が外表面側になるように用いることができる（図６）。この場合、外表面側に地組織３の面があるため、刃が当たる面においてパイル部２が偏らずに均等に保持されるため、回転刃が当たった時の防護効果が均一になり好ましい。また、着用時にパイル部２が肌側に面するため、汗を吸収しやすく、夏場の作業中であっても快適に着用することができる。 When the protective material 1 shown in FIG. 1 is used as a cut prevention tool, it can be used so that the surface of the ground tissue 3 is on the outer surface side (FIG. 6). In this case, since the surface of the ground structure 3 is on the outer surface side, the pile portion 2 is held evenly on the surface where the blade hits without being biased, so that the protective effect when the rotary blade hits becomes uniform, which is preferable. In addition, since the pile portion 2 faces the skin side when worn, it easily absorbs sweat and can be worn comfortably even during work in the summer.
　また、反対に、地組織３の面が内表面側になるように用いることもできる。この場合、着用時にパイル部２が外表面側になるので、刃が当たった際に刃に絡まりやすい。また、表面がパイル部２になるので発散性が良く好ましい。 On the contrary, it can also be used so that the surface of the ground tissue 3 is on the inner surface side. In this case, since the pile portion 2 is on the outer surface side when worn, it is likely to get entangled with the blade when it hits. Further, since the surface becomes the pile portion 2, the divergence is good and preferable.
　本発明の防護素材１によれば、繊維をパイル織してなるパイル部２を含むため、一本当たりの繊維の長さを十分に長くすることができる。したがって、従来品のように、高強度繊維からなる生地を複数層積層したものと比較して、使用する高強度繊維の総量は同程度かむしろ少量であっても、回転刃が接触した瞬間に刃に絡まって引き出される繊維のボリュームが多いため、回転刃を早く止めることができる。 According to the protective material 1 of the present invention, since the pile portion 2 formed by pile-weaving the fibers is included, the length of each fiber can be sufficiently lengthened. Therefore, even if the total amount of high-strength fibers used is the same or rather small as compared with the conventional product in which multiple layers of fabrics made of high-strength fibers are laminated, the moment the rotary blades come into contact with each other, Since the volume of fibers entwined with the blade and pulled out is large, the rotary blade can be stopped quickly.
　上述した実施の形態は、本発明の理解を容易にするための例示に過ぎず、本発明を限定して解釈するためのものではない。本発明は、その趣旨を逸脱することなく、変更、改良することができると共に、本発明にはその均等物が含まれることは言うまでもない。 The above-described embodiment is merely an example for facilitating the understanding of the present invention, and is not intended to limit the interpretation of the present invention. It goes without saying that the present invention can be modified and improved without departing from the spirit thereof, and the present invention includes an equivalent thereof.
