The artificial lawn 14 according to the present invention is made by tufting tape yarns 12 onto a primary backing 11, applying a liquid backing agent 13, and optionally backing with a net-like secondary backing or partially backing with a cushion layer. The primary lining 11 is
A fiber web 16 is laminated on an interlining 15 and needle punched to form needle prick marks 18 . The ratio is 2 to 30% by volume and the fibers are bulky, and the ratio (volume ratio) between the fiber volume ratio of the fiber web 16 on the backstitch side 17 and the bulk ratio of the solid content of the backing agent after application and drying is 1. 10 or less, and the fiber web 1 on the backstitch side 17
The total bulk ratio of the fibers in No. 6 and the solid content of the backing agent is
90% by volume or less, and is characterized in that the backing agent 13 does not penetrate through the fiber web 16 between the backstitches 17, 17' and impregnate the interlining 15.
ここに「嵩比率」とは、立体空間に占める繊維

る空隙になつていることを意味する。 Here, "bulk ratio" refers to the ratio of the volume of fibers and backing agent to the three-dimensional space, that is, the volume ratio. For example, if the fiber bulk ratio of the fiber web is 10%, 90% of the interior 16 of the fiber web is This means that it is a void occupied by air.
パイル糸のテープヤーン１２や液状バツキング
剤１３には従来慣用のものが使用される。 The tape yarn 12 of the pile yarn and the liquid backing agent 13 are conventionally used.
尚、本発明に言う「液状バツキング剤」とは、

以下、液状バツキング剤を単にバツキング剤と言
う。 In addition, the "liquid backing agent" referred to in the present invention means:
A latex emulsion compound is not a solid granule like a hot melt adhesive, but is prepared as a fluid composition containing water, an organic solvent, a plasticizer, etc. In addition, non-aqueous compositions such as polyurethane resin compositions and vinyl chloride paste resin compositions are also included.
Hereinafter, the liquid backing agent will be simply referred to as a backing agent.

ポリエステル繊維の如く接着性の少ない合成繊維
を用いるとよい。繊維ウエブ１６は、芯地１５の
バツクステツチ側１７にだけ積層するばよく両面
に積層する必要はない。 For the fiber web 16, hydrophobic synthetic fibers, preferably synthetic fibers with low adhesive properties such as polypropylene fibers, polyethylene fibers, or polyester fibers, may be used. The fibrous web 16 need only be laminated on the backstitch side 17 of the interlining 15 and need not be laminated on both sides.
ニードルパンチング針刺密度は、パイル密度即

隔をそれぞ５／23吋でパイル密度が32/5×32/5≒
41本／吋平方となる場合には、ニードルパンチン
グの針刺密度を82本／吋平方以上とする。 The needle-punching density may be greater than the pile density, that is, the needle insertion density during tufting, generally twice or more, and does not need to be as dense as when making a needle-punched felt carpet. For example, if the tuft gauge and stitch spacing are each 5/23 inches, the pile density is 32/5 x 32/5≒
In the case of 41 needles/inch square, the density of needle punching should be 82 needles/inch square or more.
一次裏地１１には、ニードルパンチングによる
針刺跡１８の残されたものが用いられる。 For the primary lining 11, a material with needle prick marks 18 left by needle punching is used.
この針刺跡１８は、繊維ウエブ１６の繊維１９

る。従つて、この針刺跡１８が塞がれその効用が
損なわない様にバツキング剤１３を塗布すること
が肝要である。 This needle puncture mark 18 is caused by the fibers 19 of the fiber web 16.
is perpendicular to the interlining 15 and forms a capillary tube that penetrates the front and back sides, and the fibers of the fiber web 16 are connected laterally and allow moisture to pass through more easily than in other areas that cover the interlining 15. It has the effect of imparting water permeability to. Therefore, it is important to apply the backing agent 13 so that the needle puncture mark 18 is closed and its effectiveness is not impaired.
又、ニードルパンチング直後の繊維ウエブ１６

以下となり、繊維ウエブ層１６に10％以上の空隙
が残存する様にバツキング剤を調製し塗布する。 In addition, the fiber web 16 immediately after needle punching
Since the hairs are fluffy and bulky and have sufficient water permeability, the backing agent 13 must be applied so that the water permeability is maintained. For this purpose, the fiber web 16 after buckling processing is
The total bulk ratio of the fibers and backing agent 13 is 90%.
The backing agent is prepared and applied so that 10% or more of voids remain in the fiber web layer 16.
そうすることによつて、水分は、ニードルパン
チングの針刺跡１８を通つて繊維ウエブ１６へと
移行し、更に、繊維ウエブ内１６の空隙を通つて
裏面へと移行し地下へと滲み出し、かくして透水
性を有する人工芝生１４が得られる。 By doing so, the moisture transfers to the fiber web 16 through the needle puncture marks 18 of the needle punching, further transfers to the back surface through the voids in the fiber web 16, and oozes underground. In this way, an artificial lawn 14 having water permeability is obtained.
慣用されるバツキング剤を使用しバツキング加
工をするには、繊維ウエブ１６は、一次裏地１１
のバツクステツチ側１７における目付が20〜300
ｇ／m2で繊維嵩比率が２〜30％と嵩高に開毛した
ものとする。 For backing using conventional backing agents, the fibrous web 16 is bonded to the primary backing 11.
The fabric weight on the backstitch side 17 is 20 to 300.
It is assumed that the hair is opened to a high bulk with a fiber bulk ratio of 2 to 30% in terms of g/m 2 .
例えば目付20ｇ／m2で嵩比率２％であれば繊維
ウエブ内に20×98≒200ｇ／m2相当量の水の入り

毛羽立たないテープヤーン１２のバツクステツチ
１７に吸収され易く、そのＵ字状に折れ曲がつた
バツクステツチ１７を伝わつて一次裏地内部に浸
入し付着する。 For example, if the fabric weight is 20g/m 2 and the bulk ratio is 2%, there will be voids in the fiber web that can enter an amount of water equivalent to 20×98≒200g/m 2 , and if the fabric weight is 300g/m 2 and the bulk ratio is 30 %, 300 x 70 = 2100 g/m 2 It has voids that can allow the equivalent amount of water to enter, and the viscous backing agent 1
3 hardly penetrates into the fluffy fiber web 16, but is easily absorbed by the back stitches 17 of the non-fuzzy tape yarn 12, and penetrates and adheres to the inside of the primary lining through the U-shaped bent back stitches 17.

７′の繊維ウエブ１６に通気透水性が保持される。 The amount of backing agent applied is usually 400 to 1000 g/m 2
When the application amount is set in this way, the backing agent adheres to the back stitch 17 and the surface of the fiber web 16, but the back stitch 17, 1
At 7', the fiber web 16 is pierced and the interlining 1
5, the backing agent attached to the surface of the fiber web 11 usually has a solid content ratio of 50% or less and contains a large amount of solution (water), and is adsorbed to the fiber surface as it dries. There are again voids between the fibers, so between the back stitches 17,1
Air permeability is maintained in the fiber web 16 of 7'.
しかし、繊維ウエブ１６の目付が20ｇ／m2以下
となる場合には繊維嵩比率が２％前後と極めて嵩

の充填された非通気性皮膜が出来てしまう。 However, when the fiber web 16 has a basis weight of 20 g/m 2 or less, even if the fiber bulk ratio is around 2%, which is very bulky and fluffy, it can be applied using a regular doctor instead of a spray. Depending on the application method, an impermeable coating film in which the fiber web 16 and the backing agent 13 are integrated will be formed.On the other hand, if the basis weight is 300 g/m 2 or more, the backstitch 17 may be used during tufting. The entire fiber web is compressed and the bulk ratio of the fibers becomes 30% or more, so that the spaces between the fibers become dense and the backing agent 13 forms an impermeable film filled with voids.
従つて、繊維ウエブの目付を20〜300ｇ／m2で
好ましくは40〜150ｇ／m2にし、繊維嵩比率を２
〜30％で好ましくは10〜20％にすることが肝要で
ある。 Therefore, the basis weight of the fiber web should be 20 to 300 g/ m2 , preferably 40 to 150 g/m2, and the fiber bulk ratio should be 2.
It is essential that it be ~30%, preferably 10-20%.
尚、本発明において「繊維ウエブの目付」及び
「繊維ウエブの繊維嵩比率」とは、芯地１５に積
層したニードルパンチング前の繊維ウエブの目付
や嵩比率ではなく、ニードルパンチング後の芯地
１５のバツクステツチ側１７に存する繊維ウエブ
の目付及び嵩比率を意味する。 In the present invention, the "fabric weight of the fibrous web" and "fiber bulk ratio of the fibrous web" are not the basis weight or bulk ratio of the fibrous web laminated on the interlining 15 before needle punching, but rather the basis weight and bulk ratio of the fibrous web after needle punching. means the basis weight and bulk ratio of the fiber web existing on the backstitch side 17 of the fiber web.
本発明におけるバツキング加工は通常のドクタ
ー方式により行われ、スプレーその他の特殊な方
式は不必要であり寧ろ不適切である。 The backing process in the present invention is carried out by a normal doctor method, and spraying or other special methods are unnecessary or even inappropriate.
何故ならスプレー方式によれば、バツキング剤
が芯地１５に付着し難くなるが繊維ウエブ１６の
極く限られた表面にだけ付着し薄いフイルム状の
非通気透水性皮膜が形成されてしまうし、又、バ

キング剤１３が浸入し難くなり、バツキング剤１
３の塗布量を増せば繊維ウエブ１６の表面に厚い
非通気透水性皮膜が形成されてしまうからであ
る。 This is because the spray method makes it difficult for the backing agent to adhere to the interlining 15, but it adheres only to a very limited surface of the fiber web 16, forming a thin film-like impermeable and water-permeable film. Also, it becomes difficult for the backing agent 13 to penetrate through the backstitch 17 to the pile 21, and the backing agent 1
This is because if the amount of coating No. 3 is increased, a thick impermeable water permeable film will be formed on the surface of the fiber web 16.
繊維ウエブ１６には通常ニードルパンチングフ
エルトカーペツトを作る場合と同様に50デニール
以下の繊維が使用される。 The fiber web 16 typically uses fibers of 50 denier or less, as in the case of making needle-punched felt carpets.
慣用されるバツキング剤１３は、その固形分比
率が通常20〜70％であつてバツクステツチ１７を

出ない適度の粘度をもつて調製されており、これ
を50デニール以上の繊維に付与すると繊維表面に
皮膜し繊維の見掛けが太くなるが、その太くなる
程度はバツキング剤の粘度に比例する。 The commonly used backing agent 13 has a solid content ratio of usually 20 to 70% and is prepared with an appropriate viscosity that does not flow from the pile root 21 to the pile surface 22 through the back stitch 17. When applied to fibers of 50 denier or more, it forms a film on the fiber surface, making the fibers appear thicker, but the degree of thickening is proportional to the viscosity of the backing agent.
バツキング剤を塗布後の繊維ウエブ内に残され

膜されて繊維の嵩が10倍以上にもなる程の厚い皮
膜が形成される程にバツキング剤が増粘されると
繊維間が粘着されてしまつて繊維ウエブ内に残さ
れる空隙は余りにも少なく細かいものとなる。 The voids left in the fiber web after applying the backing agent are those that are present between the films on the surface of the fibers that have increased in thickness. If the viscosity of the backing agent is increased to the extent that a film that is too thick is formed, the fibers will be stuck together and the voids left in the fiber web will be too small and fine.
従つてバツキング剤１３の粘度は、その皮膜に

積10％を超える空隙が残存する様に調整する。 Therefore, the viscosity of the backing agent 13 is such that the bulk ratio of the fiber volume ratio to the solid content volume ratio of the backing agent is 1:1 so that the bulk of the fibers does not increase by more than 10 times due to the film.
The amount of backing agent applied is also adjusted so that voids exceeding 10% of the volume of the fiber web 16 after backing processing remain.

実施には慣用されるバツキング剤の多くがそのま
ま使用することが出来るからである。 However, no special technology is required to adjust the viscosity or application amount of the backing agent. This is because, in conventional latex emulsion compounds, the resin content is 16 to 40% by weight, and the total solid content of the backing agent, including fillers such as calcium carbonate, is 20% by weight.
~70% by weight, and the viscosity is 1000 to 20000 c.ps, generally around 15000 c.ps. This is because the apparent thickness of the fibers does not increase more than three times, and therefore many of the backing agents commonly used can be used as they are in the practice of the present invention.
バツキング剤の塗布には慣用されるドクター塗
布装置がそのまま使用されることは前記の通りで
ある。 As mentioned above, the commonly used doctor coating device can be used as is for applying the backing agent.

れることによるものである。 As is clear from the above, the reasons why a water-permeable artificial lawn can be obtained according to the present invention are, firstly, that the interlining 15 of the primary lining is provided with needle prick marks 18 due to countless needle punchings that create a capillary action; , the fiber web 16 is the interlining 1 of the backing agent 13.
5 and promotes migration to the pile root 21 via the backstitch 17, thereby maintaining the water permeability function of the needle prick marks 18 in the interlining, and also firmly adhering the pile 20 to the primary lining 11. That,
The third reason is that the backing agent 13 does not form a water-impermeable film and the voids in the fiber web 16 are maintained.

ために適用されるものではない。 As mentioned above, the fiber web 16 in the present invention is
It can be dyed at the same time as the pile 20 to match the color of the primary lining 11 and the pile 20 to enhance the aesthetic appearance of the pile surface 22, or to support the pile root 21 and give the pile 20 a sense of volume. It is not applied to reinforce or reduce damage sustained during tufting.

後の毛羽立つたままものでよい。 Therefore, it is essential that the fibrous web 16 of the primary lining 11 be laminated on the backstitch side 17 of the interlining 15, not on the pile surface side, and be needle-punched. There is no need for an adhesive finish between the web fibers by processing, and the web may be fluffed immediately after needle punching without dyeing properties and without any post-processing such as resin processing.

発泡隆起が部分的に形成される様にすればよい。 In order to perform secondary processing without impairing water permeability, a very coarse net-like material is used as the secondary base fabric, and the adhesive used is applied to the secondary base fabric rather than to the artificial grass side. It is best to apply it to the fabric side and attach it to the artificial lawn 14. Also, to back the cushion layer, a foam sheet with many large through holes like the secondary base fabric or a foam resin composition can be used. lawn 1
It may be applied partially to the back surface of 4 in the form of dots or nets so that foaming ridges are formed partially.

As described above, according to the present invention, the water-permeable artificial lawn 14 in which water is discharged from the pile surface to the back surface through the needle puncture marks 18 and the voids in the fiber web 16 can be created using a normal backing agent or backing processing device. It can be easily obtained.

接着剤の使用量が少なくて済み経済的である。 Furthermore, when the water-permeable artificial lawn 14 according to the present invention is used as an artificial lawn for general household use that does not require water permeability, the recesses between the backstitches 17 and 17' are filled flat with the fiber web 16. Since the back stitch 17 and the fiber web 16 are flush with each other on the back side, the amount of adhesive required for construction is small, which is economical.
