ことを特徴とするものである。The artificial lawn 14 according to the present invention is produced by tufting the tape yarn 12 onto the second layer 11, applying a liquid banking agent 13, and optionally lining with a net-like secondary lining or partially applying a layer of lacelin. It is finished by backing, - the second son's fabric 11 has needle prick marks 18 made by layering the fiber web 16 on the interlining 15 and needle punching, - the back stitch of the second son's fabric 11 ? The fiber web 16 in No. 11117 has a basis weight of 20 to 300 g/
n? 2. The fiber bulk ratio is 2 to 30% by volume, and the fibers are bulky, and the ratio of the fiber volume ratio of the fiber web 16 on the bank stitch side 17 to the bulk ratio of the solid content of the backing agent after application and drying ( The total volume ratio of the fibers of the fibrous web 16 and the solid content of the backing agent on the back sketch side 17 is 90% by volume or less, and the backing agent 13 is arranged between the bank stitches 17 and 17'. It is characterized by being able to penetrate through the fiber web 16 and not impregnating the interlining 15.

物等の非水系のものも含まれる。In addition, the "liquid backing agent 1" referred to in the present invention is not a heat-adhesive hot-melt material, but is produced as a fluid composition containing water, an organic solvent, a plasticizer, etc. In addition to latex emulsion compounds, it also includes non-aqueous compounds such as polyurethane resin compositions and vinyl chloride-based 1-resin compositions.
以下、液状バッキング剤を単にバッキング剤と言う。Hereinafter, the liquid backing agent will be simply referred to as a backing agent.

である。As the interlining material 15, a nonwoven fabric may be used instead of a woven or knitted fabric, and these may be treated with ammonium water. Among these, the interlining that characterizes the present invention is a woven fabric that is densely woven without any gaps in the fabric, using monofilament tape yarn made of polyolefin resin that is easily longitudinally cracked and non-hygroscopic, for the warp and weft.

にだけ積層するばよく両面に積層する必要はない。The fibrous web 16 is made of hydrophobic synthetic fibers, preferably synthetic TJ fibers with low adhesive properties such as polypropylene fibers, polyethylene fibers, or polyester fibers. It is better to use I fiber. The fibrous web 16 is attached to the backstitch side 17 of the interlining 15.
It is not necessary to laminate both sides.

方以」−とする。The needle punching density may be more 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 5/32 inches and the pile density is 3215 x 3215 = 41 pieces/inch square, the needle density of needle punching is set to 82 pieces/inch square or more.
−次ＩＩ地１１には、ニードルパンチングによる側刺跡

塗布することが肝要である。This needle prick mark 18 forms a capillary tube in which the fibers 19 of the uIA fiber web 16 are perpendicular to the interlining 15 and penetrate from the front and back sides.
The fibers of the fibrous web 16 are connected laterally and allow moisture to permeate more easily than in other locations covering the interlining I5, and have the effect of imparting water permeability to the artificial lawn 14. Therefore, it is important to apply the backing agent 13 so that the needle puncture mark 18 is closed and its effectiveness is not diminished.

する。In addition, the fiber web 16 immediately after needle punching becomes fluffy and bulky, and has sufficient moisture permeability.
The backing agent 13 must be applied so that its moisture permeability is maintained. For this purpose, the total bulk ratio of the fibers of the fibrous web 16 and the backing agent 13 after backing processing must be 90% or less, and the fibrous web r@16 must have a total bulk ratio of 90% or less.
Apply puffing agent [JL] so that voids of % or more remain.

られる。By doing so, the moisture is transferred to the fiber web 16 through the needle puncture mark I8, and further,
The water passes through the voids in the fiber web 16 to the back surface and oozes underground, thus providing an artificial lawn 14 with water permeability.

チ側１７における日付が２０〜３００ ｇ ／ ｍで繊
維嵩比率が２〜３０％と嵩高に開毛したものとする。For banking using conventional backing agents, the fibrous web 16 is bulky with a fiber bulk ratio of 2-30% with a date of 20-300 g/m on the backstitch side 17 of the second layer 11. It is assumed that the hair is open.

チ１７を伝わって一次裏地内部に浸入し付着する。For example, if the fabric weight is 20g/cd and the bulk ratio is 2%, there will be voids in the fiber web that can enter an amount of water equivalent to 20x9B#200g/nf, and if the fabric weight is 300g/n (and the bulk ratio is 30%). If 300 x 70 = 2100g lr
The viscous backing agent 13, which has a void in which a considerable amount of water can enter, penetrates into the fluffy fiber web 1G and is easily absorbed by the backstitch 17 of the non-fuzzy tape yarn 12, which bends into a 0-shape. It penetrates into the primary lining through the backstitch 17 and adheres to it.

繊維ウェブ１１の表面に付着したバ。The amount of backing agent applied is usually 400-1000g/m
When the amount of application is set in this way, the backing agent adheres to the surface of the backstitch 17 and the fiber web 16, but it penetrates the fiber web 16 at the backstitch B old 7 and 17' and enters the interlining 15. It is difficult to penetrate to the extent that

保持される。The king agent also usually has a solid content ratio of 50% or less and contains a large amount of melt (water), and as it dries, it is adsorbed to the fiber surface, creating voids between the fibers again. Air permeability is maintained in the fibrous web 16 of 17'.

以上とｔａ維間が緻密になりバッキング剤１３によって
空隙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 or less, even if the fiber bulk ratio is around 2% and the fiber web 16 is very bulky and fluffy, ordinary application using a doctor instead of a spray can be applied. According to this method, an impermeable coating film in which the fiber web 16 and the banking agent 13 are integrated is formed.On the contrary, when the basis weight is 300 B/Id or more, the fibers are removed by backstitch I7 during tufting. The entire web is compressed and the fiber bulk ratio is 30%
As a result, the ta fibers become dense and the backing agent 13 forms an impermeable film filled with voids.
従って、繊維ウェブの目付を２０〜３００ｇ／ｉで好ま
しくは４０〜１５０ ｇ ／ｒｄにし２、繊維嵩比率を

である。Therefore, it is important that the basis weight of the fibrous web be 20 to 300 g/i, preferably 40 to 150 g/rd2, and the fiber bulk ratio be 2 to 30%, preferably 10 to 20%.
尚、本発明において「繊維ウェブの目付」及び［ｕｈ維

意味する。In the present invention, the "fabric weight of the fibrous web" and the fiber bulk ratio 1 of the fiber web after needle punching are not the basis weight or bulk ratio of the fibrous web of needle punching 11; It means the basis weight and bulk ratio of the fiber web existing in the bank stitch 011117 of the interlining 15.
本発明におけるバッキング加工は通常のドクタ一方式に
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 conventional doctor method, and spraying or other special methods are unnecessary or even inappropriate.
何故ならスプレ一方式によればバッキング剤が芯地１５

ッキング剤１３の塗布量を増せば繊維ウェブ１６の表面

。This is because according to the spray method, the backing agent is 15% of the interlining.
However, it adheres only to a very limited surface of the fiber web 16 and forms a thin film-like impermeable and water-permeable film. This is because it becomes difficult for the kinging agent 13 to penetrate, and if the amount of the backing agent 13 applied is increased, a thick impermeable water permeable film will be formed on the surface of the fibrous web 16.
繊維ウェブ１６には通常ニードルパンチングフェルトカ
ーベッ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.

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 base of the pile 21 to the pile surface 22 along the backstitch 17. When applied to fibers of 1 denier or larger, a film forms on the fiber surface and the fibers appear thicker, but the degree of thickening is proportional to the viscosity of the noking agent.

いものとなる。The voids left in the fiber web after applying the banking agent are those that are present between the films on the surface of the fibers that have increased in thickness.
When the backing agent thickens to the extent that a thick film is formed, the fibers become sticky and the voids left in the fiber web are small and fine. becomes.

る様に調整する。Therefore, the viscosity of the backing agent 13 is adjusted so that the fiber layer ratio and the banking agent solid content bulk ratio are less than 1:IO so that the bulk of the fibers does not increase by more than 10 times due to the film. Further, the amount of the backing agent applied is adjusted so that voids exceeding 10% of the volume of the fiber web 16 after buffing remain.

来るからである。No special technology is required to adjust the viscosity or application amount of the L7 backing agent. This is because the commonly used latex emulsion compound has a resin content of 16 to 40 ml.
%, the solid content of the entire banking agent including fillers such as calcium carbonate is 20 to 70% by weight, and the viscosity is i, ooo to 20,000 c, p, s, and generally f5,000 c. ,P,! Even if the fibers are soaked in a banking agent with a viscosity of around 1, taken up and dried, the apparent thickness of the fibers coated with the backing agent will not increase more than three times, and therefore, This is because many commonly used backing agents can be used as they are in the practice of the present invention.
バッ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 described above, the commonly used doctor coating device can be used as is for coating the backing agent.

ある。As is clear from the above, the reason why a water-permeable artificial lawn can be obtained according to the present invention is as follows: - Needle puncture marks 18 are created by countless needle punchings that create a capillary action on the interlining 15 of the second layer material.
secondly, the fiber web 16 prevents the banking agent 13 from penetrating into the interlining 15 and the backstitch 17
Thirdly, the pile 20 is firmly adhered to the primary lining 11 by promoting the migration to the pile root 21 through the interlining, thereby maintaining the water-permeable part of the needle prick marks 18 in the interlining. , the banking agent 13 does not form an unfortunate aqueous film within the fiber web! This is due to the fact that a gap of 6 is maintained.

。As described above, the Uk fiber reweb 16 in the present invention is dyed at the same time as the bail 20 to match the colors of the primary lining 11 and the pile 20 to enhance the aesthetic appearance of the bail surface 22, and to support the pile root 21 and form the bail 20. It cannot be used to increase the sense of volume by 1'3 or to reinforce the second son fabric 11 and reduce the damage caused during tufting.

It is an essential requirement that the fiber web be layered not on the pile side 17 but on the backstitch side 17 and needle punched.
There is no need for an adhesive finish between the Jll fibers, and the fluffy finish immediately after needle punching without dyeing properties and without any resin pressurization or other process on the rear side T may be used.

It is best to use a very coarse net-like material for the secondary base fabric, apply the adhesive to the secondary base fabric side rather than the artificial grass side, and attach it to the artificial grass 14. To line the artificial lawn 14, a foamed sheet having many large through holes is used like the secondary base fabric, or a foamed resin composition is partially applied to the back surface of the artificial lawn 14 in the form of dots or a net. The foamed ridges may be partially formed by

る。In addition, when the water-permeable artificial lawn 14 according to the present invention is used as an artificial lawn for general home use that does not require water permeability, the recesses between the back stitches 17 and 17' are filled flat with the fiber web 16. Since the back stitch 17 and the fiber web 16 are aligned flush on the back side,
It is economical because the amount of adhesive required for construction is small.
