Description

本発明は、合成樹脂製の芝葉を用いて形成された人工芝生及び人工芝生の製造方法に関するものである。   The present invention relates to an artificial lawn formed using synthetic resin turf leaves and a method for producing the artificial lawn.

単に合成樹脂製の芝葉を用いた人工芝生では、天然芝生のような風合いを得るのが困難であることから、天然芝生に近い風合いと芝葉の起立性とを両立させるべく、例えばナイロン70〜99重量%とポリエチレン1〜30重量%とからなる樹脂組成物を内層とし、ポリエチレンを外層とした複合ヤーンからなる多目的グラウンド向け人工芝用パイルヤーンが開示されている。   In artificial grass using only synthetic resin turf leaves, it is difficult to obtain a texture similar to that of a natural lawn. A multipurpose ground pile yarn for artificial turf comprising a composite yarn having an inner layer of a resin composition comprising ˜99 wt% and polyethylene of 1 to 30 wt% and polyethylene as an outer layer is disclosed.

本発明に係わる最良の実施の形態について、図面に基づき以下に具体的に説明する。   BEST MODE FOR CARRYING OUT THE INVENTION The best embodiment according to the present invention will be specifically described below with reference to the drawings.

図1は、本発明に係わる人工芝生の、実施の一形態を示す縦断面図である。人工芝生10は、ポリプロピレン樹脂製の基布2に、ポリエチレン樹脂製の芝葉1が植設され、芝葉1が植設された基布2の裏面には、芝葉1の抜け止めを図るポリウレタン系樹脂製のバッキング材3が設けられている。芝葉1は、第一の芝葉11と第二の芝葉12とからなるもので、60℃〜90℃の加熱による熱収縮率は、第二の芝葉12のほうが約5%大きくなされている。熱収縮率は、芝葉1として用いるヤーンを1mの長さに切断し、所定温度(例えば80℃)にて10分間加熱した場合の寸法の減少割合にて求めることができる。本実施形態における人工芝生10は、基布2上に充填材を充填するロングパイルタイプのものであり、第一の芝葉11の長さは40〜75mmとなされている。例えば80℃で第一の芝葉11の熱収縮率が3%、第二の芝葉12の熱収縮率が8%である場合、同一の長さで第一及び第二の芝葉1を植設し、80℃に加熱すると、第一の芝葉11と第二の芝葉12は先端付近で2〜4mmの差が生じ、この先端付近における長さのばらつきによって人工芝生10に自然な風合いを生じさせることができる。   FIG. 1 is a longitudinal sectional view showing an embodiment of an artificial lawn according to the present invention. The artificial lawn 10 has a polyethylene resin turf leaf 1 planted on a polypropylene resin base fabric 2, and the back surface of the base fabric 2 on which the turf leaf 1 is planted is intended to prevent the turf leaf 1 from coming off. A backing material 3 made of polyurethane resin is provided. The turf leaf 1 is composed of a first turf leaf 11 and a second turf leaf 12, and the thermal contraction rate by heating at 60 ° C. to 90 ° C. is about 5% larger for the second turf leaf 12. ing. The thermal contraction rate can be obtained from a reduction ratio of dimensions when a yarn used as the turf leaf 1 is cut to a length of 1 m and heated at a predetermined temperature (for example, 80 ° C.) for 10 minutes. The artificial lawn 10 in this embodiment is of a long pile type that fills the base fabric 2 with a filler, and the length of the first lawn leaf 11 is 40 to 75 mm. For example, when the heat shrinkage rate of the first turf leaf 11 is 3% and the heat shrinkage rate of the second turf leaf 12 is 8% at 80 ° C., the first and second turf leaves 1 are of the same length. When planted and heated to 80 ° C., the first turf leaf 11 and the second turf leaf 12 have a difference of 2 to 4 mm in the vicinity of the tip. A texture can be produced.

バッキング材3は、液状のポリウレタン系樹脂を基布2の裏面に塗布し、60〜100℃にて5〜15分間加熱して硬化させるものであるが、このバッキング材3の硬化温度及び時間と、複数種類の芝葉1に生じさせる所望の長さの差に合わせて、第一の芝葉11及び第二の芝葉12の熱収縮率を設定することで、芝葉1を収縮させるのに別途加熱を行う必要がなくなり、形成に係わる工程は更に簡便なものとできる。   The backing material 3 is a material in which a liquid polyurethane resin is applied to the back surface of the base fabric 2 and is cured by heating at 60 to 100 ° C. for 5 to 15 minutes. The lawn leaves 1 are contracted by setting the thermal contraction rate of the first lawn leaves 11 and the second lawn leaves 12 in accordance with the desired length difference generated in the plurality of types of lawn leaves 1. In addition, it is not necessary to perform heating separately, and the process relating to the formation can be further simplified.

芝葉1に異なる熱収縮率を具備させるには、ポリエチレン樹脂を用いた場合には、高密度ポリエチレン、中密度ポリエチレン、低密度ポリエチレン及び直鎖状低密度ポリエチレンといった、同一種類でありながら物性の異なるポリエチレン樹脂を選択して用いたり、合成樹脂中に炭酸カルシウムや木粉等の充填材を配合したり、ヤーンの成形時における延伸度合いを変更したり、これらの手段を組み合わせたりして異なる熱収縮率とすることができる。また熱収縮率の異なる芝葉1は、同一種類の合成樹脂を用いていれば二種類の熱収縮率のものに限定されず、三種類以上の熱収縮率を備えた芝葉1を用いてもよい。   In order to make the turf leaves 1 have different heat shrinkage rates, when polyethylene resin is used, the physical properties of the same kind such as high density polyethylene, medium density polyethylene, low density polyethylene and linear low density polyethylene are used. Select different polyethylene resins, use fillers such as calcium carbonate and wood flour in the synthetic resin, change the degree of stretching during the molding of the yarn, and combine these means to achieve different heat The shrinkage rate can be set. Further, the turf leaves 1 having different heat shrinkage rates are not limited to those having two types of heat shrinkage rates as long as the same type of synthetic resin is used, and turf leaves 1 having three or more types of heat shrinkage rates are used. Also good.
