Abstract

<P>PROBLEM TO BE SOLVED: To solve a problem that filling materials such as sand or rubber chips of an artificial turf with sand which is currently used in sports facilities outflow or fly out because of a wind and rain or when stepped by humans, and that the filling materials are hardened like concrete with the passage of time and have a negative effect on sports competition. <P>SOLUTION: In the processing of the tufting artificial turf, a flat-woven base cloth made of a synthetic fiber which is widely used is placed on a sheet produced by a double raschel manufacturing method which is the knitting of a three-dimensional structure, and tufting is processed on it. The tufting artificial turf is finished in a state that the double raschel sheet is placed on the pile side. In the execution of the artificial turf, when the filling materials are inserted, they penetrate into the three-dimensional structure of the double raschel, and the filling materials hardly flow out or fly out. Cushioning properties can be also obtained. Bulky nonwoven fabric having permeability can be used as a substitute for the double raschel sheet. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

本発明は、砂、ゴムチップなどを人工芝のパイルの隙間に充填し、スポーツ施設などで使用されているタフティング人工芝に関するものであり、ダブルラッセルシートを基布に又は、通気性のある嵩高性の不織布を基布に使用することによって、降雨などによる充填材の流出を抑え、透水性、クッション性を改善したものである。The present invention relates to a tufting artificial turf filled with sand, rubber chips, etc. in a pile of artificial turf, and used in sports facilities, etc. By using a non-woven fabric for the base fabric, the outflow of the filler due to rain or the like is suppressed, and the water permeability and cushioning properties are improved.

砂などの充填材が降雨などの原因で流出を防ぐため、パイル長に段差を設ける方法がある。In order to prevent the filler such as sand from flowing out due to rain or the like, there is a method of providing a step in the pile length.

Japanese Patent Laid-Open No. 2-74648

砂、ゴムチップなどの充填材を人工芝のパイルの間に入れた場合、風雨や人に踏まれる事により、充填物が流出してしまう。また、時間が経過すると充填物がコンクリートのように硬化してしまい、その人工芝の上で行われる競技のコンディションに悪影響を及ぼしている。さらに、殆どがタフティング製法で作られているため、基本的には透水機能がないため、水はけも良くない。When fillers such as sand and rubber chips are placed between piles of artificial turf, the filler will flow out due to wind and rain and being stepped on by people. In addition, as time passes, the filling hardens like concrete, which has an adverse effect on the conditions of the competition performed on the artificial grass. Furthermore, since most of them are made by tufting method, there is basically no water permeability function, so drainage is not good.

タフティング人工芝を加工するにあたり、ダブルラッセルシート又は、嵩高性の不織布など、通気性のある立体構造のベースシートにパイル糸を植毛する。ベースシートの繊維密度と糸の太さ、パイル密度によって、さらに平織シート、メッシュシートなどを2重に合わせたものにパイルを植毛することも有効である。
パイル糸の固定としては、耐水性樹脂からなる接着剤を裏面に塗布し、乾燥して仕上げる。
When processing tufting artificial turf, pile yarn is planted on a base sheet having a three-dimensional structure such as a double raschel sheet or a bulky nonwoven fabric. Depending on the fiber density of the base sheet, the thickness of the thread, and the pile density, it is also effective to plant the pile on a double sheet of plain weave sheets and mesh sheets.
For fixing the pile yarn, an adhesive made of a water-resistant resin is applied to the back surface and dried to finish.

ダブルラッセルシートはハニカム編みなどの多角形の構造を持ったシートを採用する事によって、その多角形のスペースに充填材が入り込む、充填材はダブルラッセルシートの多角形のスペースに入り、そのスペースには、上下に走る繊維が存在しており、その繊維が充填材の流動を抑える役目をはたす。また、上下に走る繊維は人工芝のクッション性を助長する。
ダブルラッセルシートは、表、裏の編みかたを変えたものがあり、タフティング人工芝としての基布として容易に使用が可能であり、それによって、従来ラッセル人工芝でしか実現できなかった透水機能が実現可能になる。
また、通気性のある嵩高不織布をダブルラッセルシートに代用することによっても、ほぼ同等の効果がある。
Double raschel sheet adopts a sheet with polygonal structure such as honeycomb knitting, so that the filler enters the polygonal space, the filler enters the polygonal space of the double raschel sheet, and in that space , There are fibers that run up and down, and the fibers play a role in suppressing the flow of the filler. In addition, the fibers that run up and down help cushion the artificial turf.
Double raschel sheets are available with different front and back knitting patterns, and can be used easily as a base fabric for tufting artificial turf. The function becomes feasible.
Further, substituting a breathable bulky nonwoven fabric for the double russell sheet has substantially the same effect.

ベース基布として、ポリプロピレンからなる平織基布とポリエステル製のハニカム構造のダブルラッセルシートを重ね合わせて、タフティングマシーンのニードル位置まで供給し、パイル糸をタフティング加工する。
ダブルラッセルシートの厚みは、人工芝のパイルをどの程度露出させ、充填材をどの程度の量を入れるかによって設定される。
パイル糸の材質はナイロン、ポリオリフィンなどで、モノフィラメント、スプリットヤーンなどの種類が適している。
また、人工芝の敷き込む現場の土質、下地により、ダブルラッセルシートと平織基布やメッシュシートを2重に合わせたり、ラミネートしたものも使用する事も有効である。
基布層とパイル糸の固定には、耐水性樹脂による接着材を塗布する。
人工芝の敷き込みにおいては、ダブルラッセルシートの繊維間隔に応じた粒子サイズの充填材をパイル面に充填する。
As the base fabric, a plain woven fabric made of polypropylene and a double raschel sheet of polyester honeycomb structure are superposed and supplied to the needle position of the tufting machine, and the pile yarn is tufted.
The thickness of the double raschel sheet is set depending on how much the artificial turf pile is exposed and how much filler is added.
The material of the pile yarn is nylon, polyolefin, etc., and monofilament, split yarn, etc. are suitable.
It is also effective to use double raschel sheets and plain woven fabrics or mesh sheets that are layered or laminated depending on the soil and groundwork on which artificial turf is laid.
An adhesive made of a water resistant resin is applied to fix the base fabric layer and the pile yarn.
In laying artificial turf, the pile surface is filled with a filler having a particle size according to the fiber spacing of the double raschel sheet.

本発明に係わる充填材保持機能付人工芝は、工業的に量産することが可能であるため、産業上の利用可能性を有している。Since the artificial turf with a filler holding function according to the present invention can be industrially mass-produced, it has industrial applicability.

ダブルラッセル立体構造編み物シートをベース基布とラミネートした物にパイルをタフティングした人工芝である。This is an artificial turf made by tufting a pile on a double raschel knitted sheet laminated with a base fabric. 通気性のある嵩高性不織布とベース基布をラミネートした物にパイルをタフティングした人工芝である。It is an artificial turf made by tufting a pile on a laminate of a breathable bulky nonwoven fabric and a base fabric.
