Description
本発明は、導電性防草シート、より詳しくは、田畑等への害獣の侵入を防ぐ電気柵の下方の地面に敷設するための導電性防草シートに関する。 TECHNICAL FIELD The present invention relates to a conductive weed control sheet, and more particularly to a conductive weed control sheet for laying on the ground below an electric fence that prevents infestation of harmful animals into fields and the like.
周知のとおり、イノシシ、タヌキ、シカ、サル等の害獣が、田畑や果樹園等に侵入し、作物等を荒らすのを防ぐための方策として、田畑等の周囲に電気柵を設置することが広く行われている。この電気柵は、田畑等の周囲に立設した複数の支柱間に裸電線を張り渡し、この裸電線に高電圧を印加したものであり、田畑等へ侵入しようとする害獣が裸電性に触れた際、その害獣に裸電線から地面へ向かう高圧電流を流すことにより、電気ショックを与え、田畑等への侵入を断念させるものである。 As is well known, pests such as boars, raccoon dogs, deer, and monkeys may install electric fences around fields to prevent crops from invading fields and orchards. It is widely practiced. In this electric fence, a bare wire is stretched between a plurality of stanchions standing around the field, and a high voltage is applied to this bare wire. When touched, the harmful animal is given a high-voltage electric current from the bare wire to the ground, which causes an electric shock and abandons the invasion of fields and the like.
ところが、この電気柵の下方で雑草が生長し、その雑草が電気柵の裸電線に接触してしまうと、裸電線の高圧電流が雑草を通じて漏電し、害獣に有効な電気ショックを与えられなくなる問題があった。 However, if weeds grow under the electric fence and the weeds come into contact with the bare wire of the electric fence, the high voltage current of the bare wire leaks through the weed, and it becomes impossible to give an effective electric shock to the pest. There was a problem.
そこで、現在までに、電気柵の下方の地面に、導電性を有する防草シートを敷設することが提案され、実施されている（例えば、下記特許文献１〜３参照）。これら防草シートは、遮光性を有し、日光を遮ることで雑草の生長を抑制するとともに、導電性を有しているため、田畑等へ侵入しようとする害獣が裸電線に触れた際、その害獣がたとえ防草シート上に乗っていたとしても、高圧電流を害獣の体から防草シートを通じて地面へ流すことができ、害獣に電気ショックを与えることができる。 Therefore, to date, it has been proposed and practiced to lay an electrically conductive weed-preventing sheet on the ground below the electric fence (see, for example, Patent Documents 1 to 3 below). These weed-preventing sheets have a light-shielding property and suppress the growth of weeds by shielding the sunlight, and also have conductivity, so that when a pest trying to enter a field touches the bare wire. Even if the pest is on a weed control sheet, high-voltage current can be passed from the body of the pest to the ground through the weed control sheet, and an electric shock can be given to the pest.
しかしながら、これら従来の導電性防草シートには以下の難点があった。即ち、特許文献１に記載の導電性防草シートは、化学繊維を織って作られた防草シートの表面側に亀甲金網を重ね、両者を止め具により接合して構成されていたため、敷設時における亀甲金網の扱いが容易でなく、敷設作業に手間がかかる難点があった。 However, these conventional conductive weed control sheets have the following drawbacks. That is, the conductive weed control sheet described in Patent Document 1 was constructed by laying a hexagonal wire net on the surface side of the weed control sheet made by weaving chemical fibers and joining both by means of a stopper. It was not easy to handle the tortoise wire mesh, and the laying work was troublesome.
また、特許文献２に記載の導電性防草シートは、炭素繊維を使用した不織布から構成されていたため、炭素繊維と他の繊維材料を混合した場合であっても、電気柵用の防草シートとして必要な導電性を得るためには十分な量の炭素繊維を混合する必要があり、その製造コストが高くなる難点があった。 Further, the conductive grass sheet described in Patent Document 2 is composed of a non-woven fabric using carbon fibers, and therefore even if the carbon fibers and other fiber materials are mixed, the grass sheet for electric fences is used. As a result, it is necessary to mix a sufficient amount of carbon fibers in order to obtain the necessary conductivity, and there is a drawback that the manufacturing cost thereof becomes high.
また、図６に示すように、特許文献３に記載の導電性防草シート１００は、帯状の化学繊維（１１１・１１２）を織って作られたシート１１０に導電物１２０を織り込んで構成されていたため、シート１１０の表裏の各面において、導電物（１２１・１２２）が断続的に表出することになり、防草シートの長期間使用による経時劣化や、害獣の踏付け等によって、シート表面側の導電物１２１が断線した場合、地面との導電性が不十分となって害獣に有効な電気ショックを与えられなくなる恐れがあった。 Further, as shown in FIG. 6, the conductive grass sheet 100 described in Patent Document 3 is configured by weaving a conductive material 120 into a sheet 110 made by weaving strip-shaped chemical fibers (111, 112). Therefore, the conductors (121 and 122) are intermittently exposed on each of the front and back surfaces of the sheet 110, and the sheet may be deteriorated over time due to long-term use of the weed-preventing sheet or trampled by a harmful animal. If the conductor 121 on the surface side is broken, the conductivity with the ground is insufficient, and there is a possibility that an effective electric shock cannot be given to the harmful animal.
勿論、この導電性防草シート１００において、シートに織り込まれた導電物１２０は、必ずしもその全長に亘って通電可能に連続している必要はなく、シート表面側で一部断線していても、その断線したシート表面側の導電物１２１がシート裏面側の導電物１２２と連続しており、そのシート裏面側の導電物１２２が地面に通電可能に接地していれば、高圧電流を害獣の体から防草シートを通じて地面へ流すことが可能である。 Of course, in this conductive weed-preventing sheet 100, the conductive material 120 woven into the sheet does not necessarily need to be continuous so that it can be energized over its entire length, and even if it is partially broken on the sheet surface side, If the conductor 121 on the front side of the sheet, which is disconnected, is continuous with the conductor 122 on the back side of the sheet, and the conductor 122 on the back side of the sheet is grounded so that it can be energized to the ground, a high voltage current will It is possible to flush from the body to the ground through the weed control sheet.
しかしながら、導電性防草シートを敷設すべき地面の状態は多様であり、シート裏面に断続的に表出している導電物１２２を全て、地面に通電可能に接地させることは望めず、実際には、図７に示すように、地面Ｇとの間に隙間があったり、石ころ等の導電不良物Ｐがあったりして、シート裏面側の導電物１２２の一部は、通電可能な接地状態にないのが通常である。 However, there are various conditions of the ground on which the conductive weed control sheet should be laid, and it is not possible to ground all the conductive materials 122 intermittently exposed on the back surface of the sheet so that the ground can be energized. As shown in FIG. 7, there is a gap between the ground G and a conductive defect P such as stones, so that a part of the conductive substance 122 on the back surface side of the seat is in a grounded state in which it can be energized. It is usually not.
したがって、長期間に亘って日中の紫外線や風雨に晒されて経時劣化が進み、更には、電気ショックを与える前後において害獣に幾度も踏み付けられるなどして、シート表面側の導電物１２１の断線箇所が多くなるほど、これらシート表面側の導電物１２１の断線部間（図７中符号Ａ参照）においてシート裏面側の導電物１２２による接地が不十分となる状態が生じ易くなり、その部分では害獣に有効な電気ショックを与えられなくなる恐れがあったのである。 Therefore, it is exposed to ultraviolet rays and wind and rain in the daytime for a long period of time to be deteriorated with time, and further, it is stepped on a harmful animal many times before and after an electric shock is applied, so that the conductive material 121 on the seat surface side As the number of disconnection points increases, a state in which the conductor 122 on the back surface side of the sheet is insufficiently grounded between the disconnection portions of the conductors 121 on the front surface side of the sheet (see symbol A in FIG. 7) is more likely to occur. There was a risk that he could not give an effective electric shock to the pests.
本発明は、従来の導電性防草シートに上記のような難点があったことに鑑みて為されたもので、電気柵による有効な電気ショックを、より長期間に亘ってより確実に害獣に与えることができる、安価で敷設作業性に優れた導電性防草シートを提供することを課題とする。 The present invention has been made in view of the above-mentioned drawbacks of the conventional conductive weed-preventing sheet, and an effective electric shock by an electric fence can be more surely ensured for a longer period of time. It is an object of the present invention to provide an electrically conductive weed proof sheet that can be applied to an inexpensive and excellent laying workability.
本発明は、害獣の侵入を防ぐ電気柵の下方の地面に敷設するための防草シートであって、遮光性を有するシート体と、前記シート体に縫い込まれた導電糸と、を備え、前記シート体の表裏各面において前記導電糸が連続的に表出していることを特徴とする。 The present invention is a weed-preventing sheet for laying on the ground below an electric fence for preventing invasion of harmful animals, comprising a light-shielding sheet body, and a conductive thread sewn into the sheet body. The conductive yarn is continuously exposed on each of the front and back surfaces of the sheet body.
また、本発明は、前記導電糸が前記シート体に本縫いされていることを特徴とする。 Further, the present invention is characterized in that the conductive thread is sewn on the sheet body.
また、本発明は、前記導電糸が前記シート体に環縫いされていることを特徴とする。 Further, the present invention is characterized in that the conductive thread is sewn around the sheet body.
また、本発明は、前記シート体が帯状の化学繊維を平織りした織布から成ることを特徴とする。 Further, the present invention is characterized in that the sheet body is made of a woven cloth in which strip-shaped chemical fibers are plain-woven.
また、本発明は、前記シート体が不織布から成ることを特徴とする。 Further, the present invention is characterized in that the sheet body is made of a non-woven fabric.
本発明に係る導電性防草シートは、シート体に導電糸を縫い込んで構成され、シート体の表裏の各面において導電糸が連続的に表出しているので、電気柵の下方の地面に敷設したとき、シート体の裏面側の導電糸は、表面側の導電糸の断線の有無に関わらず、それ自体が全長に亘って連続して通電することができる。したがって、たとえ防草シートの経時劣化や害獣の踏付け等によりシート表面側の導電糸が多数断線しても、さらに、シート裏面側の導電糸が部分的に通電可能な接地状態になくても、地面との導電性を確保することができ、電気柵による有効な電気ショックを、より長期間に亘ってより確実に害獣に与えることができる。 The conductive weed-preventing sheet according to the present invention is configured by sewing a conductive thread on a sheet body, and the conductive thread is continuously exposed on each of the front and back surfaces of the sheet body. When laid, the conductive yarn on the back surface side of the sheet body can be continuously energized over its entire length regardless of the presence or absence of disconnection of the conductive yarn on the front surface side. Therefore, even if a large number of conductive yarns on the front surface of the sheet are broken due to deterioration of the weed-preventing sheet over time, trampling of a harmful animal, etc. Also, the conductivity with the ground can be secured, and an effective electric shock by the electric fence can be given to the harmful animal more reliably for a longer period of time.
また、本発明に係る導電性防草シートは、シート体に導電糸を縫い込んで構成されているので、柔軟で取扱いが容易であり、敷設作業性に優れている。 Further, since the conductive weed-preventing sheet according to the present invention is formed by sewing conductive threads into the sheet body, it is flexible and easy to handle, and is excellent in laying workability.
また、本発明に係る導電性防草シートは、シート体に導電糸を縫い込むだけで構成することができるので、頗る安価に製造することができる。 Further, the conductive weed-preventing sheet according to the present invention can be constructed simply by sewing the conductive thread on the sheet body, and therefore can be manufactured at a very low cost.
図１〜図３に示すように、本実施形態の導電性防草シート１０は、遮光性を有するシート体１と、このシート体１に縫い込まれた導電糸２と、から構成されている。 As shown in FIGS. 1 to 3, a conductive weed-preventing sheet 10 of the present embodiment includes a sheet body 1 having a light-shielding property, and a conductive thread 2 sewn into the sheet body 1. ..
シート体１は、遮光性を有する帯状の化学繊維を縦糸１１及び緯糸１２として用いて平織りした柔軟な織布から構成されている。本実施形態では、縦糸１１及び緯糸１２として、ポリプロピレンを採用しているが、例えばポリエチレン等の他の化学繊維を採用することもできる。 The sheet body 1 is composed of a flexible woven fabric which is plain-woven using band-shaped chemical fibers having a light-shielding property as warp yarns 11 and weft yarns 12. In this embodiment, polypropylene is adopted as the warp yarn 11 and the weft yarn 12, but other chemical fibers such as polyethylene can also be adopted.
導電糸２は、上記シート体１に本縫いされている。即ち、本実施形態の導電糸２は、上糸２１と下糸２２とから成り、図３に示すように、上糸２１のループＬがシート体１の表面側から裏面側へ通り抜け、下糸２２と交差している。このことで、シート体１の表面においては、図１に示すように、導電糸２の上糸２１が各縫孔部を介して連続的に表出することになり、シート体１の裏面においては、図２に示すように、導電糸２の下糸２２が上糸２１のループＬを介して連続的に表出することになる。 The conductive thread 2 is sewn on the sheet body 1 by lock stitching. That is, the conductive thread 2 of the present embodiment is composed of the upper thread 21 and the lower thread 22, and as shown in FIG. 3, the loop L of the upper thread 21 passes from the front surface side to the back surface side of the sheet body 1 to form the lower thread. It intersects with 22. As a result, on the front surface of the sheet body 1, as shown in FIG. 1, the upper thread 21 of the conductive thread 2 is continuously exposed through each sewing hole portion, and on the back surface of the sheet body 1. As shown in FIG. 2, the lower thread 22 of the conductive thread 2 is continuously exposed through the loop L of the upper thread 21.
なお、本実施形態では、導電糸２として、アルミニウムのスリットヤーンを芯糸に螺旋状に巻きつけたカバーリング糸を採用しているが、例えば、芯糸の外表面に導電物をコーティングしたコーティング糸や、金属繊維を採用することも可能である。 In the present embodiment, as the conductive yarn 2, a cover ring yarn in which an aluminum slit yarn is spirally wound around a core yarn is adopted, but for example, a coating in which a conductive material is coated on the outer surface of the core yarn is used. It is also possible to use threads or metal fibers.
また、本実施形態では、導電糸２をシート体１の平織組織に沿って直線状に縫い込んでいるが、この導電糸２は、シート体１の組織と無関係に縫い込むことができ、例えば、シート体１の組織に対し斜め方向に縫い込んでもよく、ジグザグ状や曲線状に縫い込んでもよい。また、導電糸２の縫孔の間隔についても、帯状の化学繊維の幅やシート体１の厚み、組織等に応じて種々の設計変更が可能である。さらに、シート体１に複数の導電糸２を所要間隔で縫い込むことも可能である。 Further, in the present embodiment, the conductive thread 2 is sewn in a straight line along the plain weave structure of the sheet body 1, but the conductive thread 2 can be sewn in independently of the structure of the sheet body 1. The sheet 1 may be sewn obliquely to the tissue, or may be sewn in a zigzag shape or a curved shape. Further, the spacing between the sewing holes of the conductive thread 2 can be variously changed depending on the width of the belt-shaped chemical fiber, the thickness of the sheet body 1, the structure, and the like. Further, it is possible to sew a plurality of conductive threads 2 on the sheet body 1 at required intervals.
この導電性防草シート１０を、田畑等の周囲に設置した電気柵の下方の地面に敷設することによって、シート体１の遮光性により日光を遮って雑草の生長を抑制するとともに、導電糸２の導電性によって地面との導電性を確保して、田畑等へ侵入しようとする害獣が電気柵の裸電線に触れた際に、高圧電流を害獣の体から防草シート１０を通じて地面へ流し、害獣に有効な電気ショックを与える。 By laying this conductive weed-controlling sheet 10 on the ground below an electric fence installed around a field or the like, the light-shielding property of the sheet body 1 blocks sunlight to suppress the growth of weeds and the conductive thread 2 When the pest trying to invade the fields, etc. touches the bare wire of the electric fence, the high voltage current is sent from the pest's body to the ground through the weed-preventing sheet 10 by ensuring the conductivity with the ground by the conductivity of Sink and give an effective electric shock to the pest.
このように、本実施形態の導電性防草シート１０は、シート体１に導電糸２を縫い込んで構成され、シート体１の表裏の各面において導電糸（上糸２１、下糸２２）が連続的に表出しているので、図４に示すように、導電性防草シート１０を電気柵の下方の地面Ｇに敷設したとき、シート体１の裏面側の導電糸（下糸２２）は、表面側の導電糸（上糸２１）の断線の有無に関わらず、それ自体が全長に亘って連続して通電することができる。そして、この裏面側の導電糸（下糸２２）は、シート体１が有する遮光性により直接紫外線に晒されることもなく、また、害獣に直接、踏み付けられることもないので、長期間に亘ってその連続通電性を維持することができる。 As described above, the conductive weed-preventing sheet 10 of the present embodiment is configured by sewing the conductive thread 2 into the sheet body 1, and the conductive thread (upper thread 21 and lower thread 22) on each of the front and back surfaces of the sheet body 1. 4 are continuously exposed, as shown in FIG. 4, when the conductive grass sheet 10 is laid on the ground G below the electric fence, the conductive thread (bottom thread 22) on the back side of the sheet 1 is laid. Can continuously energize itself over the entire length, regardless of the presence or absence of disconnection of the conductive yarn (upper yarn 21) on the surface side. The conductive thread (bottom thread 22) on the back side is not directly exposed to ultraviolet rays due to the light-shielding property of the sheet body 1 and is not directly trampled by a harmful animal, so that it can be used for a long period of time. The continuous conductivity can be maintained.
したがって、図４に示すように、たとえ導電性防草シート１０の長期間使用による経時劣化や害獣の踏付け等によりシート表面側の導電糸（上糸２１）が多数断線しても、さらに、シート裏面側の導電糸（下糸２２）が、石ころ等の導電不良物Ｐの存在によって部分的に通電可能な接地状態になくても、地面Ｇとの導電性を確保することができ、電気柵による有効な電気ショックをより長期間に亘ってより確実に害獣に与えることができる。 Therefore, as shown in FIG. 4, even if a large number of conductive yarns (upper yarns 21) on the sheet surface side are broken due to deterioration over time of the conductive weed-preventing sheet 10 due to long-term use or trampling of a harmful animal, Even if the conductive thread (bottom thread 22) on the back surface side of the seat is not in a grounded state in which a conductive defect P such as stones is present, the conductivity with the ground G can be ensured. The effective electric shock by the electric fence can be given to the pest more reliably for a longer period of time.
しかも、本実施形態の導電性防草シート１０は、シート体１の表面側の導電糸（上糸２１）が連続的に表出しているので、害獣が表面側の導電糸（上糸２１）を踏む可能性を高めることができ、また、例えばイタチやハクビシン等の比較的に足裏面積の小さい害獣に対してもより確実に電気柵による電気ショックを与えることができる。 Moreover, in the conductive weed-preventing sheet 10 of the present embodiment, since the conductive yarn (upper yarn 21) on the front surface side of the sheet body 1 is continuously exposed, the harmful animal is the conductive yarn (upper yarn 21) on the front surface side. ) Can be stepped on, and an electric fence can be more reliably given an electric shock to a harmful animal such as weasel or Chinese civet that has a relatively small foot area.
また、本実施形態の導電性防草シート１０は、柔軟なシート体１に導電糸２を縫い込んで構成されているので、例えばロール巻きして運搬することができ、柔軟で取扱いが容易であり、その敷設作業性に優れている。 Further, since the conductive weed-preventing sheet 10 of the present embodiment is configured by sewing the conductive thread 2 on the flexible sheet body 1, it can be rolled and transported, for example, and is flexible and easy to handle. Yes, and its laying workability is excellent.
また、本実施形態の導電性防草シート１０は、一旦、シート体１を形成し、その後、シート体１の所望位置にミシン等により導電糸２を縫い込んで構成することができるので、頗る安価に製造することができる。また、既存の防草シートに導電糸を縫い込むことにより製造することも可能である。 Further, the conductive weed-preventing sheet 10 of the present embodiment can be constructed by once forming the sheet body 1 and then sewing the conductive thread 2 at a desired position of the sheet body 1 with a sewing machine or the like, which is satisfactory. It can be manufactured at low cost. It is also possible to manufacture it by sewing a conductive thread into an existing weed-preventing sheet.
また、本実施形態の導電性防草シート１０は、織布から成るシート体１に導電糸２を縫い込んで構成されているので、導電糸２の縫込み部分において、シート体１の縦糸１１及び緯糸１２の目寄れを防ぎ、シート体１を補強することも可能である。 Further, since the conductive weed-preventing sheet 10 of the present embodiment is configured by sewing the conductive thread 2 into the sheet body 1 made of a woven cloth, the warp thread 11 of the sheet body 1 is sewn at the conductive thread 2. It is also possible to prevent the weft yarn 12 from slipping around and to reinforce the sheet body 1.
また、上述したように、導電糸をシート体の組織とは無関係に縫い込むことができるので、例えば電気柵の設置状況や害獣の種類に応じて、シート体に対し種々の配置パターンや間隔で導電糸を縫込み配置することができ、このことによっても、より確実に電気柵による電気ショックを害獣に与えることができる。 Further, as described above, since the conductive thread can be sewn in independently of the tissue of the sheet body, various arrangement patterns and intervals for the sheet body can be set depending on the installation situation of the electric fence and the type of the pest. The conductive thread can be sewn in by means of this, and also by this, the electric shock by the electric fence can be more surely given to the pest.
以上、本実施形態の導電性防草シートについて説明したが、本発明は他の実施形態でも実施することができる。 The conductive weed-preventing sheet of the present embodiment has been described above, but the present invention can be implemented in other embodiments.
例えば、図５に示す導電性防草シート２０のように、シート体３をポリエステル繊維等から成る不織布で形成してもよい。シート体３として不織布を採用することで、シート体３の耐久性、雑草による貫通抵抗性を向上させることができる。その他、シート体として、所謂マルチシート等のフィルム材を採用してもよい。雑草の種類、地面の状態等に応じて種々の設計変更が可能である。 For example, the sheet body 3 may be formed of a non-woven fabric made of polyester fiber or the like, such as the conductive grass sheet 20 shown in FIG. By adopting a non-woven fabric as the sheet body 3, the durability of the sheet body 3 and the penetration resistance due to weeds can be improved. In addition, a film material such as a so-called multi-sheet may be adopted as the sheet body. Various design changes are possible depending on the type of weed, the condition of the ground, and the like.
また、図５に示す導電性防草シート２０のように、導電糸４がシート体３に環縫いされていてもよい。即ち、導電性防草シート２０は、一本の導電糸４がシート体３に単環縫いされており、導電糸４のループＬがシート体３の表面側から裏面側へ通り抜け、その裏面側で自糸ルーピングしている。このことで、シート体３の表面側の導電糸４１は各縫孔部を介して連続的に表出することになり、シート体３の裏面側の導電糸４２は、鎖状を成して連続的に表出することになる。 Further, the conductive thread 4 may be sewn around the sheet body 3 as in the case of the conductive grass sheet 20 shown in FIG. That is, in the conductive grass sheet 20, one conductive thread 4 is sewn on the sheet body 3 by a single loop, and the loop L of the conductive thread 4 passes through from the front surface side to the back surface side of the sheet body 3 and the back surface side thereof. I'm looping my own thread. As a result, the conductive thread 41 on the front surface side of the sheet body 3 is continuously exposed through each sewing hole portion, and the conductive thread 42 on the back surface side of the sheet body 3 forms a chain. It will appear continuously.
このように、導電糸４をシート体３に環縫いにより縫い込んだ場合でも、シート体３の表裏の各面において導電糸４が連続的に表出するので、シート体３の裏面側の導電糸４２は、表面側の導電糸４１の断線の有無に関わらず、それ自体が全長に亘って通電することができ、たとえ防草シートの長期間使用による経時劣化や害獣の踏付け等によりシート表面側の導電糸４１が多数断線しても、さらに、シート裏面側の導電糸４２が、石ころ等の導電不良物の存在によって部分的に通電可能な接地状態になくても、地面との導電性を確保することができ、電気柵による有効な電気ショックを、より長期間に亘ってより確実に害獣に与えることができる。 Thus, even when the conductive thread 4 is sewn into the sheet body 3 by chain stitching, the conductive thread 4 is continuously exposed on each of the front and back surfaces of the sheet body 3, so that the conductive surface on the back side of the sheet body 3 is electrically conductive. The yarn 42 itself can be energized over the entire length regardless of whether or not the conductive yarn 41 on the front surface side is broken. Even if the weed-preventing sheet deteriorates over time due to long-term use or is trampled by a harmful animal, etc. Even if a large number of conductive yarns 41 on the front surface side of the sheet are broken, even if the conductive yarn 42 on the rear surface side of the sheet is not in a grounded state where it can be partially energized due to the presence of conductive defects such as stones, The conductivity can be ensured, and an effective electric shock due to the electric fence can be given to the harmful animal more reliably for a longer period of time.
また、導電性防草シート２０は、導電糸４をシート体３に環縫いにより縫い込んでいるので、シート体３の裏面側の導電糸４２は、鎖状を成して二重に表出することになり、裏面側の導電糸４２の連続通電性をより向上させることができる。その他、導電糸をシート体に対し二重環縫いや偏平縫いにより縫い込むようにしてもよい。シート体の材質、厚み、地面の状態等に応じて種々の設計変更が可能である。 Further, since the conductive weed-preventing sheet 20 has the conductive thread 4 sewn into the sheet body 3 by chain stitching, the conductive thread 42 on the back surface side of the sheet body 3 forms a chain and is double exposed. As a result, the continuous conductivity of the conductive yarn 42 on the back surface side can be further improved. Alternatively, the conductive thread may be sewn into the sheet body by double chain stitch or flat stitch. Various design changes can be made according to the material, thickness, ground condition, etc. of the sheet body.
