Description

本発明は、競技場等に用いる人工芝生に関し、さらに詳しくは、運動競技場あるいは公園などに設置され、芝目内に砂などの充填物を充填して使用される競技場等に用いる人工芝生である。   The present invention relates to an artificial lawn used in a stadium, and more specifically, an artificial lawn used in a stadium or the like that is installed in an athletic stadium or a park and is filled with a filler such as sand in the turf eye. It is.

運動競技場あるいは公園などに敷設される人工芝生は、通常ポリプロピレンやナイロン等のパイル糸を基布に植設したものが広く用いられている。人工芝は、一般に、一次基布と称するポリプロピレン繊維等からなる織布に熱可塑性樹脂製のパイル糸を刺し通して（タフティング）、パイルがループした頂部をカットして芝葉をなし、ついで、裏面にラテックス材を裏打ち加工して一次基布にパイル糸を固定することにより製造されるものが多い。従来、この種の人工芝用のパイル糸としては、ポリ塩化ビニリデン、ナイロン、ポリプロピレンなどからなる合成繊維が多用されてきた。   Artificial lawns laid in athletic stadiums or parks are usually widely used in which pile yarns such as polypropylene and nylon are planted on a base fabric. Artificial grass is generally pierced with a thermoplastic resin pile thread (woven tufting) into a woven fabric made of polypropylene fiber or the like called a primary base fabric (tufting), and the top of the pile loop is cut to form grass, Many are manufactured by lining a latex material on the back surface and fixing pile yarn to the primary base fabric. Conventionally, synthetic fibers made of polyvinylidene chloride, nylon, polypropylene, and the like have been frequently used as pile yarns for this type of artificial turf.

これらの内、ポリ塩化ビニリデン製の糸条は、使用後の焼却時に有毒ガスが発生するという問題点があり、ポリプロピレン製の糸条は、耐候性や耐へたり性に劣るという欠点があり、特に砂入り人工芝として使用した場合、砂との摩擦によりパイルの先端部がフィブリル化し破断しやすいことから耐フィブリル性に劣るという問題があった。   Among these, the polyvinylidene chloride yarn has a problem that toxic gas is generated at the time of incineration after use, and the polypropylene yarn has the disadvantage of being inferior in weather resistance and sag resistance, In particular, when used as artificial turf containing sand, there is a problem that the tip of the pile is fibrillated due to friction with sand and easily breaks, resulting in poor fibril resistance.

そこで、耐フィブリル性を改良する目的で、例えば、メルトフローレートが０．５〜５．０ｇ／１０分のポリプロピレン９５〜６５重量％および密度が０．９１８〜０．９４０ｇ／ｃｍ３の線状ポリエチレン５〜３５重量％を含有する樹脂組成物を基材とする一軸延伸物よりなる人工芝生用原糸（特許文献１）が、また、プロピレンとプロピレン以外のα−オレフィンとのランダム共重合体を基材とすることを特徴とする人工芝用パイル糸（特許文献２）が、また、密度が０．９１８〜０．９４０ｇ／ｃｍ３の線状ポリエチレン９７〜７０重量パーセントに対してポリプロピレン３〜３０重量パーセントを含有する混合樹脂組成物より成る一軸延伸条をパイル糸として植設したことを特徴とする人工芝生（特許文献３）が、さらには、密度が０．９１８〜０．９４０ｇ／ｃｍ３の線状ポリエチレン９５〜２０重量パーセントに対して、高密度ポリエチレン５〜８０重量パーセントを含有する混合樹脂組成物より成る一軸延伸条からパイル糸を構成し、植設したことを特徴とする人工芝生（特許文献４）、などが提案されている。

しかしながら、上記提案方法では、耐フィブリル特性が改善されているが、その効果は十分とはいえず、また、得られるパイル糸の柔軟性が不十分で、しかも、加工性が劣るという問題もあった。
本発明は、上記した問題点を解消するためになされるものであり、高密度ポリエチレンを主成分とする人工芝パイル用糸条であって、単体の繊維として耐フィブリル性、耐衝撃性、加工性に優れ、且つ柔軟性に優れた糸条、及びそれによる耐久性の優れた砂入れ人工芝生を提供することを目的とする。 However, although the above-mentioned proposed method has improved fibril resistance, the effect is not sufficient, and there is also a problem that the pile yarn obtained is insufficiently flexible and has poor workability. It was.
The present invention is made in order to solve the above-described problems, and is a yarn for artificial turf pile mainly composed of high-density polyethylene, and has a fibril resistance, an impact resistance and a processing as a single fiber. An object of the present invention is to provide a yarn having excellent properties and flexibility, and an artificial sand lawn with excellent durability.

本発明の要旨は、高密度ポリエチレン７０〜９５重量％とメタロセン触媒による密度が０．９０〜０．９２５ｇ／ｃｍ３のエチレン・α−オレフィン共重合体５〜３０重量％との組成物からなる人工芝用パイル糸に存する。 The gist of the present invention consists of a composition of 70 to 95% by weight of high density polyethylene and 5 to 30% by weight of an ethylene / α-olefin copolymer having a density of 0.90 to 0.925 g / cm 3 based on a metallocene catalyst. It exists in pile yarn for artificial grass.

本発明の人工芝用パイル糸は、高密度ポリエチレン７０〜９５重量％とメタロセン触媒による密度が０．９０〜０．９２５のエチレン・α−オレフィン共重合体５〜３０重量％との組成物からなるもので、耐フィブリル性が著しく改良され、人工芝生の耐久性を向上するものである。   The pile yarn for artificial turf of the present invention comprises a composition of 70 to 95% by weight of high density polyethylene and 5 to 30% by weight of an ethylene / α-olefin copolymer having a density of 0.90 to 0.925 based on a metallocene catalyst. Thus, the fibril resistance is remarkably improved, and the durability of the artificial lawn is improved.

以下、本発明を詳細に説明する。
本発明で用いられる高密度ポリエチレンは、密度が０.９４５〜０.９６０ｇ／ｃｍ３が好ましく、公知のチーグラー触媒等を用いて中低圧法で製造される。高密度ポリエチレンのメルトフローレート（以下、ＭＦＲと称す）は０.１〜３０ｇ／１０ｍｉｎが好ましく、１〜１０ｇ／１０ｍｉｎがより好ましい。 Hereinafter, the present invention will be described in detail.
The high density polyethylene used in the present invention preferably has a density of 0.945 to 0.960 g / cm 3 and is produced by a medium-low pressure method using a known Ziegler catalyst or the like. The melt flow rate (hereinafter referred to as MFR) of the high density polyethylene is preferably 0.1 to 30 g / 10 min, and more preferably 1 to 10 g / 10 min.

本発明で用いられるエチレン・α−オレフィン共重合体は、マグネシウムおよびチタンを含有する固体触媒成分と有機アルミニウム化合物からなる、メタロセン触媒を用いて重合して得られるもので、例えば、密度０.９０〜０.９２５ｇ／ｃｍ３の中密度および低密度ポリエチレン、あるいは密度０.８８〜０.９１ｇ／ｃｍ３の超低密度線状ポリエチレンといわれるものを包含する。 The ethylene / α-olefin copolymer used in the present invention is obtained by polymerization using a metallocene catalyst composed of a solid catalyst component containing magnesium and titanium and an organoaluminum compound, and has a density of 0.90, for example. including density and low density polyethylene in the ~0.925g / cm 3, or of a density 0.88~0.91g / cm 3 what is referred to as ultra low density linear polyethylene.

前記中密度および低密度ポリエチレン、あるいは超低密度線状ポリエチレンのα−オレフィンとしては、炭素数３〜８のもの、すなわちプロピレン、１−ブテン、１−ペンテン、４−メチル−１−ペンテン、１−ヘプテン、１−ヘキセン、１−オクテンなどが用いられ、特に１−ブテンおよび１−ヘキセンが好ましい。   As the α-olefin of the medium density and low density polyethylene or the ultra low density linear polyethylene, those having 3 to 8 carbon atoms, that is, propylene, 1-butene, 1-pentene, 4-methyl-1-pentene, 1 -Heptene, 1-hexene, 1-octene and the like are used, and 1-butene and 1-hexene are particularly preferable.

上記高密度ポリエチレンとエチレン・α−オレフィン共重合体の配合割合は、高密度ポリエチレン７０〜９５重量％とエチレン・α−オレフィン共重合体５〜３５重量、好ましくは高密度ポリエチレン７０〜９０重量％とエチレン・α−オレフィン共重合体１０〜３０重量％の範囲である。即ち、エチレン・α−オレフィン共重合体が５重量％未満では耐フィブリル性の改良効果が期待できず、３０重量％を超えると圧縮回復力を損なうため問題となる。   The blending ratio of the high density polyethylene and the ethylene / α-olefin copolymer is 70 to 95% by weight of the high density polyethylene and 5 to 35% by weight of the ethylene / α-olefin copolymer, preferably 70 to 90% by weight of the high density polyethylene. And 10 to 30% by weight of ethylene / α-olefin copolymer. That is, if the ethylene / α-olefin copolymer is less than 5% by weight, the effect of improving the fibril resistance cannot be expected, and if it exceeds 30% by weight, the compression recovery force is impaired, which causes a problem.

本発明に樹脂組成物には、その使用目的により本発明の主旨を逸脱しない範囲において、紫外線吸収剤、光安定剤、酸化防止剤、滑剤、難燃剤、帯電防止剤、無機充填剤、架橋剤、発泡剤、着色剤等の添加剤を配合してもよい。   The resin composition according to the present invention includes an ultraviolet absorber, a light stabilizer, an antioxidant, a lubricant, a flame retardant, an antistatic agent, an inorganic filler, and a crosslinking agent as long as they do not depart from the gist of the present invention. In addition, additives such as a foaming agent and a coloring agent may be blended.

本発明の人工芝パイル用糸条は、前述の樹脂組成物から紡糸し成形された糸条である。糸条の形態は特に制限されることはなく、例えば、紡糸ノズルから押出し延伸したモノフィラメント、偏平モノフィラメント、或いはフィルム成形した後に細断してテ−プ状となし延伸したフラットヤ−ンやスプリットヤ−ンなどである。糸条は、パイルに用いるにあたり、熱圧縮ギア法、ニットデニット法、スタフィング法、エアジェット法など公知の方法を採用して捲縮加工を施すことができる。   The yarn for artificial turf pile of the present invention is a yarn formed by spinning from the above resin composition. The form of the yarn is not particularly limited. For example, a monofilament extruded from a spinning nozzle, a flat monofilament, or a flat yarn or split yarn that is cut into a tape shape and then stretched into a tape shape. Etc. The yarn can be crimped by using a known method such as a heat compression gear method, a knit denit method, a stuffing method, or an air jet method when used for a pile.

本発明の人工芝パイル用糸条の厚みは、好ましくは８０〜２００μｍ、より好ましくは１００〜１８０μｍである。厚みが８０μｍ以下では厚みが薄いために砂などの充填物との摩擦により引きちぎられやすく、耐フィブリル性に劣り、２００μｍ以上ではパイル糸状の剛性が増しタフティング性が劣る。   The thickness of the yarn for artificial turf pile of the present invention is preferably 80 to 200 μm, more preferably 100 to 180 μm. When the thickness is 80 μm or less, the thickness is thin, and therefore, it is easily torn by friction with a filler such as sand, resulting in poor fibril resistance, and when it is 200 μm or more, the pile yarn-like rigidity is increased and tufting property is inferior.

上記フラットヤーンの成形方法は、上記混合物を押出機を用いて溶融押出し、Ｔダイ法またはインフレーション法にてフィルムを成形し、一旦冷却固化したフィルムをスリットした後延伸可能な温度まで再加熱して延伸し、次いで熱処理してフラットヤーンを形成する。このフラットヤーンは、さらに回転する針布ロールなどで割繊してスプリットヤーンとすることもできる。ここでの延伸温度は、好ましくは７０〜１２０℃、より好ましくは８０〜１１０度である。延伸温度が７０℃未満では白化が生じたり延伸性が低下し、１２０℃を超えると熱収縮率が低下して好ましくない。また延伸倍率は好ましくは５〜１２倍、より好ましくは８〜１０倍である。延伸倍率が５倍より小さいと機械的強力が不十分となり、１２倍より大きいと糸割れを生じて好ましくない。延伸の際の加熱方式としては、熱ロール式、熱板式、赤外線式、熱風式等いずれの方式も採用できる。   The flat yarn is formed by melt-extruding the mixture using an extruder, forming a film by the T-die method or inflation method, slitting the cooled and solidified film, and then reheating it to a temperature at which it can be stretched. Drawing and then heat treating to form a flat yarn. This flat yarn can also be split into yarns by splitting with a rotating cloth roll or the like. The stretching temperature here is preferably 70 to 120 ° C., more preferably 80 to 110 degrees. If the stretching temperature is less than 70 ° C., whitening occurs or the stretchability is lowered, and if it exceeds 120 ° C., the thermal shrinkage rate is undesirably lowered. The draw ratio is preferably 5 to 12 times, more preferably 8 to 10 times. If the draw ratio is less than 5 times, the mechanical strength is insufficient, and if it is more than 12 times, yarn breakage is unfavorable. As a heating method at the time of stretching, any method such as a hot roll type, a hot plate type, an infrared type and a hot air type can be adopted.

The width of the flat yarn is preferably 0.5 to 50 mm, more preferably 2 to 20 mm, and the thickness is preferably 80 to 200 μm, more preferably 100 to 180 μm. This flat yarn can be used alone or as a heat-shrinkable pile yarn by twisting a plurality of flat yarns.

上記モノフィラメント、扁平モノフィラメントの成形方法は公知のモノフィラメント成形法を用いて成形される。上記モノフィラメント、扁平モノフィラメントの単糸繊度は好ましくは２００〜２，０００ｄｔで、１本単独で、あるいは複数本撚り加工して熱収縮性パイル糸として用いることができる。   The monofilament and the flat monofilament are molded using a known monofilament molding method. The monofilaments and flat monofilaments preferably have a single yarn fineness of 200 to 2,000 dt, and can be used alone or as a heat-shrinkable pile yarn by twisting a plurality.
