Description

ゴルフショットマットGolf shot mat
　本発明はゴルフショットマットに関する。さらに詳しくは、練習場に本発明のゴルフショットマットを敷いてショットしたときの感覚と同じ感覚でゴルフコースで実践のショットをした場合、練習場でのショットが実践のショットに再現されやすく、一方、実践のショットが練習場でのショットに再現されやすい、ショットの再現性に優れたゴルフショットマットに関する。 The present invention relates to a golf shot mat. In more detail, when a practical shot is made on a golf course with the same feeling as when shooting with the golf shot mat of the present invention on the practice field, the shot on the practice field is easily reproduced as a practical shot, The present invention relates to a golf shot mat excellent in shot reproducibility, in which practice shots are easily reproduced as shots in a practice field.
　通常、ゴルフ練習場に設置されているショットマットは、人工芝でパイルの毛足が４～１０ｍｍ程度である。この場合、アイアンによるショット時にゴルフボールの手前にゴルフクラブのフェースが落ち、いわゆるダフッた状態となっても、リーディングエッジがショットマット上を滑ることにより、ゴルフボールをうまく捕まえることができてナイスショットにつながることがある。よって、練習者は、たとえダフッた状態でゴルフボールを打ち続けた場合でも気持ちよく練習場でナイスショットを連発できることがある。しかし、ゴルフ上級者の間では、ゴルフ練習場での練習の成果がゴルフコースでの実践のショットに繋がらないという問題が囁かれている。 Usually, shot mats installed at golf driving ranges have artificial grass and pile hairs of about 4 to 10 mm. In this case, even if the golf club face falls in front of the golf ball during a shot with an iron and becomes so-called duffy, the leading edge slides on the shot mat, so the golf ball can be caught well and a nice shot May lead to Therefore, even if the practitioner continues to hit the golf ball in a duffy state, the practitioner may be able to fire nice shots at the practice field comfortably. However, there is a problem among advanced golfers that the result of practice at a driving range does not lead to a shot of practice at a golf course.
　この種の先行技術としては、天然芝同様の打感を再現すべく天然芝をカートリッジ内に養生し、カートリッジ毎、入れ替える芝生カートリッジゴルフマットが提案されている（特許文献１参照）。この提案であれば、天然芝通りの打感を体感できるものの、使用寿命が極端に短く、新たに育成された芝のカートリッジを設置しなければならず、工業的観点および実用性の点で適切とは言えない。 As this type of prior art, there has been proposed a turf cartridge golf mat in which natural turf is cured in a cartridge in order to reproduce a feel similar to that of natural turf, and the cartridges are replaced (see Patent Document 1). With this proposal, you can feel the feel of natural turf, but you have to install a newly cultivated turf cartridge with an extremely short service life, which is appropriate from an industrial and practical point of view. It can not be said.
　また、人工芝原反の下部に５～５０ｍｍのクッション層を備え、打撃感覚に優れ、特にクラブの振り抜きが良いゴルフ練習用アイアンマットが提案されている（特許文献２）。この提案では、パイル長さは１０～１５ｍｍの範囲であり、ショット時にパイルがボールとクラブとの間で噛むことは少なく、振り抜きが良く気持ちよい打感を得られるが、人工芝による抵抗感が少ないので、いわゆるダフリを体感することは難しく、すべてのショットがナイスショットにつながりやすい。そのため、ゴルフコースでの実践のショットにおいてミスショットをした場合に、その感覚と同じ感覚で特許文献２に記載のアイアンマットで練習場でショットをしてもナイスショットになって、実践のショットを再現できない。従って、ミスショットの原因をつかむことができないという欠点がある。 Also, an iron mat for golf practice has been proposed that has a cushion layer of 5 to 50 mm under the artificial turf original fabric and is excellent in hitting feeling, and particularly good for swinging out a club (Patent Document 2). In this proposal, the pile length is in the range of 10 to 15 mm, and the pile is less likely to bite between the ball and the club at the time of the shot, and the swinging is good and a pleasant feel can be obtained. Because there are few, it is difficult to experience the so-called duff, and all shots are likely to lead to nice shots. Therefore, when a miss shot is made in a practical shot on a golf course, even if it is shot at a practice field with the iron mat described in Patent Document 2 with the same sense, it becomes a nice shot and a practical shot is taken. It cannot be reproduced. Therefore, there is a drawback that the cause of the miss shot cannot be grasped.

　本発明は従来技術の有する上記問題点に鑑みてされたものであって、その目的は、練習場でのショットと実践のショットとのあいだにおいてショットの再現性に優れたゴルフショットマットを提供することにある。 The present invention has been made in view of the above-mentioned problems of the prior art, and an object thereof is to provide a golf shot mat excellent in shot reproducibility between shots at a practice field and actual shots. There is.
　本発明は上記の課題を解決するために、次のように構成したものである。
　すなわち本発明は、ゴルフショットマットに関し、ポリアミド繊維パイル糸による人工芝からなるゴルフショットマットであって、タフトされたポリアミド繊維パイル糸が、仮撚り捲縮を有する弱捲縮糸Ａと座屈捲縮を有する強捲縮糸Ｂからなり、以下の条件（１）～（５）の全てを満足することを特徴とする。　
　（１）ＡＳＴＭ　Ｅ３０３に準拠して求めた湿潤時における滑り抵抗値が４５ＢＰＮ以上、９０ＢＰＮ未満　
　（２）パイル高さが２０ｍｍ以上、３５ｍｍ未満　
　（３）パイル糸の目付が１０００ｇ／ｍ２以上
　（４）ゴルフボールを静置したときのゴルフボールの沈み量が８ｍｍ以上２２ｍｍ未満
　（５）動的荷重による厚さ減少率が１５％以下 In order to solve the above-mentioned problems, the present invention is configured as follows.
That is, the present invention relates to a golf shot mat, which is a golf shot mat made of artificial turf made of polyamide fiber pile yarn, wherein the tufted polyamide fiber pile yarn is weakly crimped yarn A having a false twist crimp and buckling buckle. It is composed of a strong crimped yarn B having a shrinkage and satisfies all of the following conditions (1) to (5).
(1) Slip resistance value when wet determined in accordance with ASTM E303 is 45 BPN or more and less than 90 BPN
(2) Pile height is 20mm or more and less than 35mm
(3) The pile yarn weight per unit area is 1000 g / m 2 or more. (4) The golf ball sinks when the golf ball is left standing is 8 mm or more and less than 22 mm. (5) The thickness reduction rate due to dynamic load is 15% or less.
　上記の本発明のゴルフショットマットに用いるパイル糸はポリアミド繊維であり、仮撚り捲縮を有する弱捲縮糸Ａと座屈捲縮を有する強捲縮糸Ｂからなる。パイル糸がポリアミド繊維であることにより、ゴルフクラブの打球部分（フェースを含むヘッド部分に相当する箇所）がこのゴルフショットマットと強く接触しても、パイル糸が耐摩擦性および耐摩耗性に優れているので、パイルが一旦毛倒れしても、もとの状態に回復する回復性が優れている。 The pile yarn used in the golf shot mat of the present invention is a polyamide fiber, and is composed of a weakly crimped yarn A having false twist crimps and a strong crimped yarn B having buckling crimps. Since the pile yarn is a polyamide fiber, the pile yarn has excellent friction resistance and wear resistance even when the hitting portion of the golf club (the portion corresponding to the head portion including the face) is in strong contact with the golf shot mat. Therefore, even if a pile falls down once, the recoverability which recovers to the original state is excellent.
　上記の本発明のゴルフショットマットは、ＡＳＴＭ　Ｅ３０３に準拠して求めた湿潤時における滑り抵抗値が４５ＢＰＮ以上、９０ＢＰＮ未満である。滑り抵抗値が４５ＢＰＮ未満では、ゴルフクラブの打球部分がマット上を滑ってゴルフボールをうまく捕えることができて、練習者は、いわゆるダフりをすることなく、ナイスショットをしてしまう。そのため、実践のショットでは再現することができない、誤った打点の感覚を覚えてしまう。一方、滑り抵抗値が９０ＢＰＮ以上であると、マットの抵抗が天然芝に比べて大きすぎ、練習者の手首や肘を痛める原因となる。 The golf shot mat of the present invention described above has a sliding resistance value of 45 BPN or more and less than 90 BPN when wet according to ASTM E303. When the slip resistance value is less than 45 BPN, the hitting portion of the golf club can slide on the mat and catch the golf ball well, and the practitioner makes a nice shot without so-called duffing. For this reason, the user feels a sense of wrong hitting points that cannot be reproduced with actual shots. On the other hand, if the slip resistance value is 90 BPN or more, the resistance of the mat is too large compared to natural turf, causing damage to the wrist and elbow of the practitioner.
　本発明のゴルフショットマットのパイル高さは２０ｍｍ以上、３５ｍｍ未満である。本発明のパイル高さとは、より高い方の糸のパイル高さを言い、弱捲縮糸Ａのパイル高さがこれに当たり、弱捲縮糸Ａの中の最も高い糸の高さが本発明のパイル高さである。そもそもパイル高さが２０ｍｍ未満であると、ゴルフクラブの打球部分がパイル上を滑りやすくなり、パイルを噛みこむことなく、いわゆるダフることなくショットできてしまう。ゴルフ練習場で一般的に使用されているマットのパイル高さは２０ｍｍ未満であるから、練習者のスイングが良くなくても、気持ち良い振り抜きの打感を楽しめるので、練習中毒となる人もいる。一方、パイル高さが３５ｍｍ以上となると、ゴルフクラブの打球部分がパイルの中に大きく潜ることとなり、抵抗感が強くなるばかりか、極端にボールを打ち辛くなる。 The pile height of the golf shot mat of the present invention is 20 mm or more and less than 35 mm. The pile height of the present invention refers to the pile height of the higher yarn, which corresponds to the pile height of the weakly crimped yarn A, and the highest yarn height in the weakly crimped yarn A is the present invention. The pile height. In the first place, if the pile height is less than 20 mm, the hitting portion of the golf club becomes slippery on the pile, and the shot can be shot without biting the pile and so-called duffing. Mats generally used at golf driving ranges have a pile height of less than 20mm, so even if the practitioner's swing is not good, you can enjoy a pleasant swing feeling, so some people are addicted to practice . On the other hand, when the pile height is 35 mm or more, the hitting portion of the golf club is greatly dive into the pile, and the resistance becomes strong and the ball becomes extremely difficult to hit.
　本発明のゴルフショットマットのパイル糸の目付は１０００ｇ／ｍ２以上である。パイル糸の目付が１０００ｇ／ｍ２未満であるとショット時に底つき感があり、硬い地面を叩いているような感覚となりゴルフコースでの打感と大きく乖離する。 The basis weight of the pile yarn of the golf shot mat of the present invention is 1000 g / m 2 or more. If the basis weight of the pile yarn is less than 1000 g / m 2 , there is a feeling of bottoming at the time of a shot, and it feels like hitting a hard ground, which is greatly different from the feeling of hitting on a golf course.
　本発明のゴルフショットマットは、ゴルフショットマット上にゴルフボールを静置したときのゴルフボールの沈み量が８ｍｍ以上２０ｍｍ未満である。ゴルフボールの直径は、４２．６７ｍｍである。これに対し、８ｍｍ未満の沈み量では、芝（パイル糸）の抵抗を感じない打点で打つことになり、真の練習に成り得ない。一方、２０ｍｍ以上の沈み量では、少なくともゴルフボールの下半分は、完全に沈んだ状態である。ラフに入った想定ともいえるが、常にこの状態で練習するのは、ショット時の衝撃が大きいので、練習者の手首やひじに大きな負担を掛ける原因となる。 The golf shot mat of the present invention has a golf ball sinking amount of 8 mm or more and less than 20 mm when the golf ball is placed on the golf shot mat. The golf ball has a diameter of 42.67 mm. On the other hand, if the sinking amount is less than 8 mm, it will be hit with a hitting point that does not feel the resistance of the lawn (pile yarn), and it cannot be a true practice. On the other hand, when the sinking amount is 20 mm or more, at least the lower half of the golf ball is completely sinking. It can be said that it is assumed to be in the rough, but always practicing in this state causes a great burden on the wrist and elbow of the practitioner because of the impact at the time of the shot.
　本発明のゴルフショットマットの動的荷重による厚さ減少率は１５％以下である。動的荷重による厚さ減少率が１５％より大きいと、パイル糸の糸切れや摩耗が激しいことを意味し、ショットマットとしては、耐久性が脆弱なものとなる。なお、動的荷重による厚さ減少率とは、ＪＩＳ Ｌ １０２１－７：２００７「繊維製床敷物試験方法」の「第７部：動的荷重による厚さ減少試験方法」に準拠して測定した数値をいう。 The thickness reduction rate due to the dynamic load of the golf shot mat of the present invention is 15% or less. If the thickness reduction rate due to dynamic load is greater than 15%, it means that the pile yarn is severely broken and worn, and the durability of the shot mat is weak. The thickness reduction rate due to dynamic load was measured in accordance with “Part 7: Thickness reduction test method due to dynamic load” in JIS L 1021-7: 2007 “Fiber floor covering test method”. This is a numerical value.
　本発明のゴルフショットマットのパイル糸がポリアミド繊維であることにより、耐摩擦性および耐摩耗性に優れており、パイルが一旦毛倒れしても、もとの状態に回復する回復性が優れている。　
　また、本発明のゴルフショットマットは、ＡＳＴＭ　Ｅ３０３に準拠して求めた湿潤時における滑り抵抗値が４５ＢＰＮ以上、９０ＢＰＮ未満であることにより、肉体を痛めることなく、練習場でのショットを実践のショットで忠実に再現し、実践でのショットを練習場のショットで忠実に再現することができる。　
　また、本発明のゴルフショットマットのパイル高さは２０ｍｍ以上、３５ｍｍ未満であることにより、肉体に過度の負担を与えることなく、練習場でのショットと実践でのショットの再現性を高めることができる。　
　また、本発明のゴルフショットマットのパイル糸の目付は１０００ｇ／ｍ２以上であることにより、練習場での打感とゴルフコースでの打感が一致する。
　さらに、本発明のゴルフショットマットは、ゴルフショットマット上にゴルフボールを静置したときのゴルフボールの沈み量が８ｍｍ以上２０ｍｍ未満であることにより、肉体を痛めることなく、実践で役にたつショットを練習することができる。
　そして、本発明のゴルフショットマットの動的荷重による厚さ減少率が１５％以下であることにより、耐久性を向上することができる。 Since the pile yarn of the golf shot mat of the present invention is a polyamide fiber, it has excellent friction resistance and wear resistance, and even when the pile falls once, it has excellent recoverability to recover to its original state. Yes.
In addition, the golf shot mat of the present invention has a slip resistance value when wet determined in accordance with ASTM E303 of 45 BPN or more and less than 90 BPN. Can be faithfully reproduced, and the shot in practice can be faithfully reproduced in the shot of the practice field.
In addition, the pile height of the golf shot mat of the present invention is 20 mm or more and less than 35 mm, so that the reproducibility of shots in practice fields and shots in practice can be improved without imposing an excessive burden on the body. it can.
Moreover, when the weight of the pile yarn of the golf shot mat of the present invention is 1000 g / m 2 or more, the hit feeling at the practice field and the hit feeling at the golf course match.
Furthermore, the golf shot mat of the present invention has a golf ball sinking amount when the golf ball is placed on the golf shot mat is not less than 8 mm and less than 20 mm. Can practice.
And durability can be improved because the thickness decreasing rate by the dynamic load of the golf shot mat of this invention is 15% or less.

　以下、本発明についてさらに詳細に説明する。図１は本発明に係るゴルフショットマット１の実施の一形態を示す断面図であり、２は弱捲縮糸Ａ、３は強捲縮糸Ｂ、４は基布、５はバッキング材、６は樹脂シートである。 Hereinafter, the present invention will be described in more detail. FIG. 1 is a cross-sectional view showing an embodiment of a golf shot mat 1 according to the present invention, wherein 2 is a weakly crimped yarn A, 3 is a strong crimped yarn B, 4 is a base fabric, 5 is a backing material, 6 Is a resin sheet.
　まず、本発明のゴルフショットマットに用いられるパイル糸について説明する。本発明のゴルフショットマットに用いられるパイル糸はポリアミド繊維である。ポリアミドとしては、例えば、ナイロン６、ナイロン６６、ナイロン６１０、ナイロン１１、ナイロン１２、ナイロン６１２、ナイロンＭＸＤ６およびこれらの各成分の組み合わせからなる共重合ポリアミドなどがあげられるが、なかでもナイロン６およびナイロン６６が好ましく使用される。具体的な共重合成分としては、ε－カプロアミド、テトラメチレンアジパミド、ヘキサメチレンセバカミド、テトラメチレンイソフタルアミド、テトラメチレンテレフタラミドおよびキシリレンフタラミドなどが挙げられる。ポリアミド繊維に添加する顔料としては、有機物、無機物の何れでも差支えなく、一般的には、カーボンブラック、ベンガラ、フタロシアニン系の顔料が好ましく用いられる。パイル糸の断面形状としては、特に限定しないが、人工芝としての外観を考慮すると偏平断面（すなわち、糸長手方向に対して垂直に切断した単糸の断面が扁平であること）が好ましく、図２に基づいて下記式で求められる偏平率が４００（％）～１０００（％）であることが好ましい。図２において、７はパイル単糸である。
　扁平率（％）＝［（Ｂ）／（Ａ）］×１００
　　（Ａ）：単糸短辺部の最大径
　　（Ｂ）：単糸長辺部の最大径
扁平率が１０００（％）を超えて極端に偏平度を大きくすると耐久性が損なわれるため好ましくない。また、よりリアルに芝の葉を表現したり、表面光沢（テカリ）を減少させるため、パイル糸の表面に凹凸形状を付与したり、パイル糸の表面を波形状にすることは好ましい。 First, the pile yarn used for the golf shot mat of the present invention will be described. The pile yarn used for the golf shot mat of the present invention is a polyamide fiber. Examples of the polyamide include nylon 6, nylon 66, nylon 610, nylon 11, nylon 12, nylon 612, nylon MXD6, and copolymerized polyamides composed of combinations of these components, among which nylon 6 and nylon 66 is preferably used. Specific examples of the copolymer component include ε-caproamide, tetramethylene adipamide, hexamethylene sebacamide, tetramethylene isophthalamide, tetramethylene terephthalamide, and xylylene phthalamide. The pigment added to the polyamide fiber may be either organic or inorganic, and carbon black, bengara, or phthalocyanine pigments are generally preferably used. The cross-sectional shape of the pile yarn is not particularly limited, but in view of the appearance as an artificial turf, a flat cross-section (that is, the cross-section of a single yarn cut perpendicular to the longitudinal direction of the yarn is flat) is preferable. Preferably, the flatness ratio obtained from the following formula based on 2 is 400 (%) to 1000 (%). In FIG. 2, 7 is a pile single yarn.
Flatness ratio (%) = [(B) / (A)] × 100
(A): Maximum diameter of single yarn short side portion (B): If the maximum diameter flatness of the single yarn long side portion exceeds 1000 (%) and the flatness is extremely increased, durability is impaired. Further, in order to more realistically represent turf leaves and reduce surface gloss (shine), it is preferable to provide an uneven shape on the surface of the pile yarn, or to make the surface of the pile yarn corrugated.
　本発明に用いられるパイル糸の形態としては捲縮を有しており、仮撚り捲縮を有する弱捲縮糸Ａと座屈捲縮を有する強捲縮糸Ｂからなる。弱捲縮糸Ａの仮撚り捲縮とは、撚り係数が低仮撚り数で施される微弱捲縮のことを言う。一方、座屈捲縮を有する強捲縮糸Ｂとは、乾熱あるいは湿熱のスタッフィング（押し込み）加工糸、針布あるいはネットに高温水蒸気を吹付けた高捲縮糸などをいう。 The pile yarn used in the present invention has a crimp, and includes a weakly crimped yarn A having a false twist crimp and a strong crimped yarn B having a buckling crimp. The false twist crimp of the weakly crimped yarn A refers to a slightly weak crimp that is applied at a low false twist number. On the other hand, the strong crimped yarn B having buckling crimp refers to dry heat or wet heat stuffing (push-in) processed yarn, high crimped yarn obtained by spraying high-temperature water vapor on a needle cloth or a net, and the like.
　これら弱捲縮糸Ａおよび強捲縮糸Ｂは引き揃えられてタフトされるのであるが、その捲縮差のためにタフト後、パイル高さに差が生じる。前記弱捲縮糸Ａの方が前記強捲縮糸Ｂよりも２ｍｍ以上突出していることが好ましい。弱捲縮糸Ａが２ｍｍ以上突出することにより、強捲縮糸Ｂが沈み糸としての役割を果たし、弱捲縮糸Ａが毛倒れしても立毛回復を促進する。なお、パイル高さが高く、突出している弱捲縮糸Ａのことを浮き糸と言い、これに対して、捲縮が強く縮みながら弱捲縮糸Ａの根本を支えている強捲縮糸Ｂを沈み糸と言う。 These weak crimped yarns A and strong crimped yarns B are aligned and tufted, but due to the crimp difference, a difference in pile height occurs after tufting. It is preferable that the weakly crimped yarn A protrudes 2 mm or more than the strongly crimped yarn B. When the weakly crimped yarn A protrudes by 2 mm or more, the strongly crimped yarn B serves as a sinking yarn, and even if the weakly crimped yarn A falls down, the napped recovery is promoted. Note that the weakly crimped yarn A having a high pile height and protruding is called a floating yarn. On the other hand, the strongly crimped yarn A that supports the root of the weakly crimped yarn A while the crimp is strongly contracted. B is called a sinking thread.
　前記強捲縮糸Ｂの伸縮復元率が５％以上、２０％未満であることが好ましい。強捲縮糸Ｂの伸縮復元率が５％未満であると糸の捲縮が小さく、前記弱捲縮糸Ａの立毛性が悪化したり、ゴルフクラブの打球部分がマット上を滑りやすくなるという問題がある。一方、強捲縮糸Ｂの伸縮復元率が２０％以上であると、マット上で強捲縮糸Ｂが著しく縮み、ゴルフクラブが強捲縮糸Ｂの中に“ざっくり”入らず、その上を滑ってしまいやすくなり、ダフリが再現できにくいという不都合がある。なお、伸縮復元率とは、ＪＩＳ Ｌ １０１３：２０１０「化学フィラメント糸試験方法」の「８．１２　伸縮復元率」に準じて測定した数値をいう。 The stretch recovery rate of the strong crimped yarn B is preferably 5% or more and less than 20%. When the stretch recovery rate of the strong crimped yarn B is less than 5%, the crimp of the yarn is small, the napping property of the weak crimped yarn A is deteriorated, and the hitting portion of the golf club becomes slippery on the mat. There's a problem. On the other hand, if the expansion / contraction restoration rate of the strong crimped yarn B is 20% or more, the strong crimped yarn B is remarkably shrunk on the mat, and the golf club does not “roughly” enter the strong crimped yarn B. There is a disadvantage that it is difficult to reproduce duff. The expansion / contraction recovery rate is a numerical value measured according to “8.12 Expansion / contraction recovery rate” of JIS L 1013: 2010 “Chemical Filament Yarn Test Method”.
　前記弱捲縮糸Ａの１本当たりのフィラメントの繊度が４００デシテックス以上であり、前記強捲縮糸Ｂよりも大きいことが好ましい。前記弱捲縮糸Ａの１本当たりのフィラメントの繊度が４００デシテックス未満であれば、前記弱捲縮糸Ａが毛倒れしやすく、毛倒れした後も回復性に乏しい。前記弱捲縮糸Ａの１本当たりのフィラメントの繊度が前記強捲縮糸Ｂよりも小さければ、繰り返しゴルフクラブによる衝撃を受けた後、前記強捲縮糸Ｂよりも前記弱捲縮糸Ａが突出した部分で、前記弱捲縮糸Ａが毛折れしたり、糸切れしやすくなるので、耐久性の観点から好ましくない。 The fineness per filament of the weakly crimped yarn A is preferably 400 dtex or more, and is preferably larger than that of the strongly crimped yarn B. If the fineness of the filaments per weakly crimped yarn A is less than 400 dtex, the weakly crimped yarn A is likely to fall down, and poor recoverability even after falling down. If the fineness of one filament of the weakly crimped yarn A is smaller than that of the strong crimped yarn B, the weakly crimped yarn A is more than the strongly crimped yarn B after being repeatedly impacted by a golf club. Since the weakly crimped yarn A is broken or easily broken at the protruding portion, it is not preferable from the viewpoint of durability.
　次に、本発明のゴルフショットマットについて、さらに説明する。 Next, the golf shot mat of the present invention will be further described.
　本発明のゴルフショットマットは、ポリアミド繊維パイル糸をタフトした人工芝からなる。 The golf shot mat of the present invention is made of artificial turf with tufted polyamide fiber pile yarn.
　本発明のゴルフショットマットは、ＡＳＴＭ　Ｅ３０３に準拠して求めた湿潤時における滑り抵抗値が４５ＢＰＮ以上、９０ＢＰＮ未満である。滑り抵抗値を４５ＢＰＮ以上、９０ＢＰＮ未満とすることにより、ゴルフコース上での実践のショットと近似した抵抗感をゴルフクラブが受ける。このため、スイングに相応してクラブフェイスが開いたり閉じたり、あるいは、いわゆる“ざっくり”や“ダフリ”等のミスショットを再現することができる。 The golf shot mat of the present invention has a sliding resistance value of 45 BPN or more and less than 90 BPN when wet in accordance with ASTM E303. By setting the slip resistance value to 45 BPN or more and less than 90 BPN, the golf club receives a sense of resistance that approximates a practical shot on a golf course. For this reason, the club face can be opened or closed in accordance with the swing, or a misshot such as so-called “rough” or “duffle” can be reproduced.
　本発明のゴルフショットマットのパイル高さは２０ｍｍ以上、３５ｍｍ未満である。パイル高さが２０ｍｍ未満であるとゴルフクラブの打球部分がマット上を滑って、いわゆるダフリが再現しにくく、パイル糸からの抵抗感も感じることができない。一方、パイル高さが３５ｍｍ以上になるとゴルフクラブの打球部分がパイル中を大きく潜り、大きな抵抗力を受けるため手首を痛める原因となる。また、打つ度にマットへの衝撃ダメージも大きなものとなり、極端に耐久性の低いものとなる。 The pile height of the golf shot mat of the present invention is 20 mm or more and less than 35 mm. If the pile height is less than 20 mm, the hitting portion of the golf club slides on the mat, so that so-called duffing is difficult to reproduce, and resistance from the pile yarn cannot be felt. On the other hand, when the pile height is 35 mm or more, the hitting portion of the golf club is greatly dived in the pile and receives a great resistance, which causes the wrist to be damaged. In addition, the impact damage to the mat increases every time it is struck, resulting in extremely low durability.
　本発明のゴルフショットマットのパイル糸の目付は１０００ｇ／ｍ２以上である。パイル糸の目付が１０００ｇ／ｍ２未満であるとショット時に底つき感があり、硬い地面を叩いているような感覚となりコースでの打感と大きく乖離する。 The basis weight of the pile yarn of the golf shot mat of the present invention is 1000 g / m 2 or more. If the basis weight of the pile yarn is less than 1000 g / m 2 , there is a feeling of bottoming at the time of a shot, and it feels like hitting a hard ground, which is greatly different from the feel on the course.
　本発明のゴルフショットマットはゴルフボールを静置したときのゴルフボールの沈み量が８ｍｍ以上２０ｍｍ未満である。８ｍｍ未満の沈み量では、芝（パイル糸）の抵抗を感じない打点で打つことになり、真の練習に成り得ない。一方、２０ｍｍ以上の沈み量では、少なくともゴルフボールの下半分は、完全に沈んだ状態である。ラフに入った想定ともいえるが、常にこの状態で練習するのは、ショット時の衝撃が大きく練習者の手首やひじに大きな負担を掛ける原因となる。 The golf shot mat of the present invention has a golf ball sinking amount of 8 mm or more and less than 20 mm when the golf ball is left standing. If the sinking amount is less than 8 mm, it will be hit with a spot that does not feel the resistance of the turf (pile yarn), and it cannot be a true practice. On the other hand, when the sinking amount is 20 mm or more, at least the lower half of the golf ball is completely sinking. It can be said that it is assumed that it is in the rough, but always practicing in this state causes a large impact on the wrist and elbow of the practitioner due to the impact on the shot.
　本発明のゴルフショットマットの動的荷重による厚さ減少率は１５％以下である。動的荷重による厚さ減少率が１５％より大きいと、パイル糸の糸切れや摩耗が激しいことを意味し、ショットマットとしては、耐久性が脆弱なものとなる。 The thickness reduction rate due to the dynamic load of the golf shot mat of the present invention is 15% or less. If the thickness reduction rate due to dynamic load is greater than 15%, it means that the pile yarn is severely broken and worn, and the durability of the shot mat is weak.
　本発明のゴルフショットマットに砂やゴムチップなどを充填することは、ショット時にそれらの飛散を招くので好ましくない。 It is not preferable to fill the golf shot mat of the present invention with sand or rubber chips because they cause scattering during the shot.

　表１に示すように、本発明の実施例１ないし４のゴルフショットマットは、抵抗感とダフリ再現性において天然芝とほぼ同等の特性を備えているので、練習場でのショットと実践のショットとのあいだにおいてショットの再現性に優れている。しかし、比較例１と比較例２のゴルフショットマットは、滑り抵抗値、パイル高さ、パイル糸の目付、ゴルフボールの沈み量および動的荷重における厚さ減少率のすべてにおいて必要な条件を満足していないので、抵抗感とダフリ再現性において天然芝と同等の特性を備えていない。 As shown in Table 1, the golf shot mats of Examples 1 to 4 of the present invention have almost the same characteristics as natural turf in resistance and duffing reproducibility. The reproducibility of shots is excellent. However, the golf shot mats of Comparative Example 1 and Comparative Example 2 satisfy the necessary conditions in all of the slip resistance value, pile height, pile yarn weight, golf ball sinking amount, and thickness reduction rate under dynamic load. Therefore, it does not have the same characteristics as natural turf in resistance and duffing reproducibility.
　本発明のゴルフショットマットは、ショット時の抵抗感が天然芝と近似であり、ゴルフコースでの実践のショットと、練習場でのショットとの再現性に優れているので、世界を目指すジュニア育成、さらに上を目指す上級者向けの練習用マットとして有用である。 The golf shot mat of the present invention is similar in resistance to natural turf when shot, and is excellent in reproducibility of shots on the golf course and shots on the practice field. It is useful as a practice mat for advanced players who want to go further.
