Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is a plate-shaped base made of plastic, which is formed by integrally projecting elongated leaf-like bodies in the shape of grass on substantially the entire surface or a part of the surface of the base. The present invention relates to an antistatic artificial turf that is configured to be capable of sequentially attenuating, by corona discharge, static electricity generated by friction with footwear and the like in artificial turf that is laid and used in such cases.

[0002]

2. Description of the Related Art Artificial turf, in which slender leaf-like bodies are integrally and densely projected on a surface of a plate-shaped base made of plastic, can be colored almost arbitrarily and has a good appearance. It has many features such as good walking sensation because well-closed leaf-shaped bodies serve as cushions. Therefore, it is widely used indoors and outdoors on floors, aisles, and other places. However, since the plastic used for artificial turf is generally an electric conductor, static electricity is often generated and accumulated due to human walking or other friction.
Therefore, when the static electricity accumulated in the artificial turf is transferred to the walking human body to give an impact, or when a person whose static electricity is transferred from the artificial turf comes into contact with a metal, the static electricity is discharged to the person. A shock may occur.
Further, since the static electricity accumulated on the artificial turf adsorbs dust and the like, the artificial turf may be contaminated by the adsorbed dust and the like.

As described above, the static electricity accumulated in the artificial turf has various effects on the human body and the like, and therefore, artificial turf which is prevented from being charged is already known. For example, an artificial turf to which a surfactant is added in advance as an antistatic agent is known. However, since the surfactant gradually exudes from the artificial grass, the antistatic effect is relatively short-lasting.

As an artificial turf for which the antistatic effect lasts, as an artificial turf for sequentially attenuating the accumulated static electricity by corona discharge to prevent the occurrence of the influence, for example,
The one disclosed in Japanese Utility Model Publication No. 59-23589 is known. This artificial turf is made of plastic by projecting elongated fronds integrally on a plate-shaped base. Then, a fiber made of a metal such as stainless steel, copper or aluminum, or a conductive short fiber formed by a method such as plating or vapor-depositing a film of a metal such as copper on the surface of a synthetic fiber such as carbon fiber or polyamides is formed. An appropriate amount is arranged, and the end portion of the discharge member is planted in a brush shape on a support made of plastic to form a discharge member. This discharge member is dispersed and positioned between the leaves of the artificial turf, and the protrusion provided on the support is inserted into the recess provided on the base, and the discharge member is attached to the upper surface of the base to The conductive short fibers are arranged in the vicinity.

[0005] In the artificial turf, static electricity is generated in the frond due to friction between the frond and the footwear of a pedestrian, etc., and as the charge accumulates on the artificial turf and its charge increases, The electric potential of the electrically conductive short fibers arranged nearby is also high. When the electric potential of the electrically conductive short fibers becomes high to some extent, a high electric field is generated at the tip of the electrically conductive short fibers to cause dielectric breakdown and corona discharge occurs. The electrostatic charge of the artificial turf is repeatedly attenuated by this corona discharge, and the electrostatic charge of the artificial turf is kept small to the extent that no influence occurs.

An antistatic artificial grass in which the discharge member is formed of plastic into the shape of a small artificial grass and the discharge members are arranged in a dispersed manner is also available, for example, in Japanese Utility Model Publication Sho 63-187977.
No. 6,086,045. This discharge member is formed by integrally forming a plurality of leaf-shaped bodies on the end portion of the support, and is integrally formed by a plastic in which conductive short fibers are mixed in advance. Then, a corona discharge is generated at the end of the conductive short fiber exposed on a part of the surface of the discharge member formed entirely of plastic, and the accumulated static electricity is attenuated by attenuating the static electricity of the artificial grass. It is intended to prevent the influence that occurs based on. .

[0007]

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
The artificial turf disclosed in Japanese Patent No. 589 is one in which corona discharge is generated in the conductive short fibers dispersed in the base and arranged in a standing manner to attenuate the static electricity accumulated in the artificial turf. Therefore, it is possible to continuously maintain the effect of attenuating the static electricity of the artificial turf, and it is possible to solve the influence of the static electricity of the artificial turf almost completely.

However, since it is necessary to arrange an appropriate amount of conductive short fibers and to plant the ends of the conductive short fibers on a support to provide a discharge member, it takes a lot of time and labor to form this discharge member. There is. Moreover, since it is necessary to disperse and attach a plurality of the discharge members to the base between the leaves of the artificial turf, there is a problem that the time and effort required to attach the discharge members are considerably increased. Also, since the discharge member formed separately from the artificial turf is attached to the base of the artificial turf in an upright state, if the leaves of the artificial turf are repeatedly stepped on by footwear of a pedestrian, at that time It occurs that the discharge member is also pressurized at the same time. Therefore, there is a possibility that the discharge member is also pressed to fall into a laid state as the leaf member is deformed by pressure, and the support member of the discharge member is separated from the base of the artificial turf. As described above, when the discharge member is separated from the artificial turf, the discharge member may be moved or discarded, which makes it difficult to expect a sufficient discharge effect of the static electricity of the artificial turf.

The discharge member of the artificial turf disclosed in Japanese Utility Model Laid-Open No. 63-187977 is integrally molded with plastic in which conductive short fibers are mixed in advance, so that the discharge member is relatively efficient. It can be well formed. However, this discharge member causes corona discharge at the ends of the conductive short fibers that are exposed on the surface of the discharge member while being aware of the amount of the conductive short fibers exposed on the surface of the discharge member. Control is difficult.

Therefore, in some cases, the amount of the conductive short fibers exposed on the surface of the discharge member is almost sufficient to generate corona discharge. However, conversely, there may be a case where the conductive short fibers that are exposed on the surface of the discharge member are almost absent or extremely small, which causes a problem that the variation in the exposed amount of the conductive short fibers becomes extremely large. Since variations in the exposed amount of the conductive short fibers cause variations in the occurrence of corona discharge, there are cases where the static electricity of the artificial grass cannot be sufficiently attenuated. It is possible to increase the exposed amount of the conductive short fibers by increasing the mixed amount of the conductive short fibers with respect to the plastic, but mixing a large amount of the conductive short fibers causes a problem of high cost. Further, most of the conductive short fibers mixed in a large amount are embedded in the plastic constituting the discharge member and are not used for generating corona discharge, so the use efficiency of the conductive short fibers for corona discharge generation is high. There are some issues that are extremely low.

The present invention solves the above problems by efficiently disposing and fixing conductive fibers on an artificial turf, and by performing corona discharge relatively evenly on almost the entire artificial turf. The purpose is to obtain an antistatic artificial grass capable of sufficiently reducing the static electricity of the artificial grass.

[0012]

The antistatic artificial turf of the present invention is an artificial turf in which a slender plastic leaf-like body is erected on one side of a base made of plastic in a plate shape. It is characterized in that conductive fibers cut to an appropriate length are scattered from the surface side of the standing leaflets, and the artificial grass is bonded to the surface of the artificial grass with an adhesive having the conductive fibers scattered.

The artificial grass can be formed of any plastic, and the adhesive for adhering the conductive fibers to the artificial grass is made of any plastic that can be bonded to the plastic constituting the artificial grass. Things can be used. Examples of the plastic constituting the artificial grass and the adhesive include ethylene-vinyl acetate copolymer (EVA), polyethylene and polypropylene. It is suitable that the artificial turf and the adhesive are made of the same kind of plastic to firmly bond the adhesive to the artificial turf. However, it is also possible to use an adhesive composed of a plastic different from the artificial grass that can adhere to the artificial grass.

The plastics forming the artificial turf and the adhesive for fixing the conductive fibers to the surface of the artificial turf include, for example, weather resistance improvers or softeners such as pigments, antioxidants and antioxidants, plasticizers and the like. It is possible to add the above-mentioned additive as required. As the adhesive, as described above, for example, when the artificial grass is formed of EVA, it is possible to use an EVA adhesive of the same quality to firmly bond the adhesive to the artificial grass. It is suitable for firmly fixing conductive fibers. As the adhesive, any type of adhesive such as a hot-melt adhesive, an adhesive that is used by heating and melting, or a solvent-type or emulsion-type adhesive that has a relatively long bondable time is used. It is possible to

The base may be formed in a plate-like net shape by providing a large number of through holes at substantially the entire space, or may be formed in a plate-like shape without holes as a whole. . The leaf-shaped body erected on the base is arbitrary such as having a semicircular or triangular cross-section, a circular shape in cross section, and the leaf-shaped body is erected standing side by side in a lattice along the entire lattice-shaped base. Alternatively, it is optional that the bases provided with or without holes are arranged side by side in a ring shape and the leaf-shaped bodies standing in the ring shape are dispersed and arranged at intervals.

Since the leaf-shaped body is formed into a linear shape, it is optional that the tip portion of the leaf-shaped material is heated and bent to be used as an artificial grass, or the linear shape is used as an artificial grass. And when bending the tip of the frond,
When the leaves are in a straight line, the conductive fibers are sprayed and adhered to the artificial grass with an adhesive, and then the tip of the leaves is bent by heating. It is also possible to heat and bend the tip portion of the frond body, and then sprinkle the conductive fiber and bond it to the artificial grass with an adhesive. The selection of the conductive fiber application time for this artificial turf is suitable for the application of conductive fibers from between the leaves to the base, etc., depending on the density of the leaves and the bent state of the tip. To do.

As the conductive fibers, carbon fibers, fibers made of metal such as stainless steel, copper and aluminum, or synthetic fibers made of polyamide and the like are formed by a method such as plating and vapor deposition, and a metal film such as copper and aluminum. Examples of the fiber include a fiber coated with and imparting conductivity. The conductive fiber may have any cross-sectional shape such as a circular cross-section or a tape-shaped flat cross section. The length of the conductive fiber is arbitrary, and when the base is formed of a perforated plate,
It is suitable to have a length that does not pass through the holes of the base.
If the base has no holes, the length should be suitable for bonding with a scattered adhesive. Therefore, the length of the conductive fiber may be, for example, about 3 mm to 50 mm. The conductive fibers can be adhesively arranged over almost the entire surface of the artificial grass, and by partially masking the artificial grass with a sheet or the like,
It is also possible to bond and arrange it to a part of the artificial grass.

The adhesion of the conductive fibers to the artificial grass by means of an adhesive is carried out by first spraying the conductive fibers on the artificial grass, and then by spraying an adhesive (binder) of the type or hot-melt type used by heating and melting. Then, the conductive fibers scattered by the adhesive are bonded to the artificial grass. In addition, an adhesive of a solvent type or emulsion type, which has a relatively long bondable time, is first sprinkled and adhered to the surface of the artificial turf, then conductive fibers are sprinkled, and the conductive fibers are adhered as described above. It is possible to make it optional such as adhering to an agent.

As described above, the conductive fibers are first sprayed on the artificial turf, and then an adhesive of a type or hot-melt type to be used by heating and melting is sprayed. Then, a considerable amount of the conductive fibers previously sprayed move to the surface portion of the base, and are placed on the surface portion of the base, and the amount of locking on the surface of the frond is small. Become. Therefore, it is easy to arrange the conductive fiber on the base side by adhesion.
On the contrary, an adhesive such as a solvent type or an emulsion type, which can be adhered for a relatively long time, is first sprayed on the artificial turf, and then conductive fibers are sprayed. Then, the conductive fibers are adhered and arranged on the adhesive adhered to the base surface, and the dispersed conductive fibers are also adhered to the adhesive adhered on the surface of the frond body, so that the conductive surface is also electrically conductive on the surface of the frond body. It is easy to arrange the fibers by adhesion. The application of the adhesive to the artificial turf is optional, such as dropping in drops or in a line, or spraying with a spray device. Unbonded conductive fibers are removed from the artificial grass and reused.

Further, the antistatic artificial grass of the present invention is formed of plastic into a plate shape, and has a grass-like elongated plastic leaf-like body on one surface of a base provided with a large number of through holes at substantially the same intervals. On the artificial turf in which the tip end of the leaf-shaped body is bent, and from the surface opposite to the surface on which the leaf-shaped body is erected, a length of a length that can pass through the through-hole. It is also characterized in that conductive fibers are dispersed and the conductive fibers that have passed through the through-holes are bonded to the surface of the artificial turf with an adhesive that has been dispersed through the through-holes.

The through hole provided in the plate-shaped base may be formed in any shape such as a square shape or a circular shape.
The length of the conductive fiber is selected so that it can be dispersed and passed through the through hole and is suitable for bonding with an adhesive. The plastic and the material of the conductive fiber forming the artificial grass, or the adhesive and the like for bonding the conductive fiber should be the same as the case of spraying the conductive fiber from the surface side where the leaf is erected. It is possible.

[0022]

As described above, the antistatic artificial grass of the present invention has a structure in which the conductive grass is sprinkled with conductive fibers and the conductive grass is adhered to the artificial grass with an adhesive. The time and effort required for disposing and fixing the conductive fibers are reduced, and it is possible to efficiently dispose and fix the conductive fibers. In addition, since the conductive fibers can be arranged almost all over the artificial grass, it is possible to efficiently attenuate the static electricity of the artificial grass by corona discharge of the conductive fibers. The density of the conductive fibers adhered to the surface of the artificial turf can be adjusted substantially according to the amount of each of the conductive fibers and the adhesive sprayed.

When the above-mentioned conductive fibers are sprinkled from the standing surface side and adhered, a large amount of the conductive fibers are dispersed and adhered to the surface of the base in a tilted state. Therefore, even if it is repeated that the frond is stepped on with a footwear, there is almost no risk of the conductive fibers peeling from the surface of the artificial grass, and even if the conductive fibers peel from the artificial grass, the artificial grass Since the amount of the conductive fibers to be peeled off is extremely small compared to the total amount of the conductive fibers adhered to the surface of, the effect of attenuating static electricity by corona discharge is not affected.

On the other hand, when the conductive fibers are sprinkled from the surface side on which the leaves are not erected and the conductive fibers are passed through the through holes of the base and adhered to the surface of the artificial turf, the tip end portion is trapped. More conductive fibers adhere to the side of the bent leaf that faces the base. Therefore, even when the leaf-shaped body is stepped on with footwear, the footwear and the like almost never come into direct contact with the conductive fibers, so that the conductive fibers are prevented from peeling off from the surface of the artificial grass. Is possible. In addition, the amount of adhesive that adheres to the exposed surface of the frond is reduced and the appearance is improved.

[0025]

[First Embodiment] Fig. 1 shows a first embodiment of an antistatic artificial grass of the present invention.
3 will be described. In FIGS. 1 to 3, 1 is an artificial grass made of ethylene-vinyl acetate copolymer, 2 is a plate-shaped rectangular base, which has a large number of rectangular through-holes 3 at intervals. Are formed in a lattice shape, and the artificial turf 1 is formed on one surface of the base 2 by vertically arranging slender leaf-like bodies 4 in a grass shape at intervals. When the artificial turf 1 is molded by a mold, each leaf-shaped body 4 is almost straight as shown in FIG. 3, but the tip portion of the straight-shaped leaf-shaped body 4 is heated and bent. I am letting you. The bending of the tip portion of each of the leaves 4 is, for example,
The tip portion of the leaf-shaped body 4 is bent by plastic deformation by pressurizing and heating with a hot plate heated to a temperature equal to or lower than its softening temperature. Reference numeral 5 is a support leg projecting in a rod shape on the other surface of the base 2 at a distance, 6 is a pipe-shaped connecting portion provided at a distance over two sides of the base 2, and 7 is another 2 of the base 2.
It is a rod-shaped insertion portion formed over the side, and is formed so that it can be inserted into the connection portion 6 and locked.

Reference numeral 8 is a carbon fiber as a conductive fiber which is dispersed and adhered to the surface of the artificial grass 1 on which the leaves 4 are erected. Each carbon fiber 8 is an ethylene-acetic acid constituting the artificial grass 1. It is adhered to the artificial turf 1 with a hot-melt adhesive 9 composed of an ethylene-vinyl acetate copolymer of the same quality as the vinyl copolymer. One side of the through hole 3 is about 7 mm
The carbon fiber 8 has a length of about 10
It is set to ~ 15mm. Although FIG. 1 shows a state in which the carbon fibers 8 are adhered to the surface of the base 2 only with the adhesive 9, the carbon fibers 8 are adhered to the surface of the leaves 4 in accordance with conditions such as the intervals between the leaves 4. The carbon fibers 8 bonded by the agent 9 are also produced.

As shown in FIG. 3A, the carbon fibers 8 are arranged and adhered to the artificial turf 1 by artificially molding the leaf-shaped bodies 4 linearly with respect to the plate-shaped base 2. The turf 1 is arranged horizontally with its leaflets 4 facing upward. Then, the carbon fibers 8 housed in the fiber spraying device 10 arranged at a distance above the artificial grass 1 are dropped onto the surface of the artificial grass 1, and the artificial grass 1 is slid at a low speed to obtain the carbon fibers. 8 are dispersed on the entire surface of the artificial turf 1 and dropped. Then, since the leaf-shaped bodies 4 are erected at intervals and are straight in the entire length, the carbon fibers 8 dropped from the fiber spraying device 10 onto the artificial grass 1 can be relatively easily. Some of them pass through the spaces between the leaves 4 and are dispersed over the entire surface of the base 2 and overlap each other in a tilted state, and some of the leaves 4 come to rest between the leaves 4.

Next, as shown in FIG. 3B, an adhesive blowing pipe 11 for blowing the adhesive in a linear shape and dropping it.
The artificial grass 1 on which the carbon fibers 8 are dispersed is arranged on the lower side, and is conveyed at a low speed while being rotated linearly or in a spiral shape so that the adhesive blowing pipe 11 becomes a linear shape or the like. Adhesive 9 that blows out in the shape of a shower
Adhere to the surface of. A part of the adhesive 9 attached to the surface of the artificial grass 1 overlaps with a part of the carbon fibers 8 that have been sprayed, so that the carbon fibers 8 are covered with the artificial grass 1.
Adhere to the surface of. After the adhesive 8 has hardened, the unbonded carbon fibers 8 are removed from the artificial turf 1 and the tip of the leaf 4 is heated by a hot plate (not shown) heated to a temperature not higher than the softening temperature of the leaf 4. The artificial turf 1 shown in FIG. 1 is obtained by pressing and heating the portion to bend it. It is also possible to remove the unbonded carbon fibers 8 from the artificial grass 1 after bending the tip portion of the leaf-shaped body 4.

As described above, the carbon fibers 8 are sprinkled on the surface of the artificial turf 1, and the carbon fibers 8 are adhered to the surface of the artificial turf 1 with the adhesive 9 to be dispersed on the surface of the artificial turf 1. The carbon fibers 8 are arranged and fixed. Therefore, the carbon fibers 8 can be efficiently arranged with respect to the artificial grass 1, and the carbon fibers 8 can be efficiently adhered. Then, as shown in FIG. 3, the leaves 4 spray the carbon fibers 8 on the linear artificial grass 1, so that even when the density of the leaves 4 is relatively high, the above-mentioned surface of the base 2, It is easy to dispose the dispersed carbon fibers 8, and it is possible to disperse the carbon fibers 8 substantially evenly or partially in the artificial turf 1 evenly.

The carbon fiber 8 is the base 2 of the artificial grass 1.
Since it is dispersed and adhered to the surface of the leaf-shaped body 4, even if the leaf-shaped body 4 is repeatedly stepped on with a footwear, the carbon fibers 8 are less likely to be peeled from the artificial grass 1. . Even if the carbon fiber 8 is peeled from the artificial grass 1,
Since the amount is extremely small, the static electricity of the artificial grass 1 can be efficiently attenuated by the corona discharge of the carbon fibers 8 for a long period of time. In this antistatic artificial turf, when the electrostatic charge accumulated in the artificial turf 1 becomes large due to the friction between the footwear and the leaves 4, the potential of the carbon fiber 8 also becomes high, and the carbon fiber 8 is exposed. Corona discharge is generated from the end portion to attenuate the static electricity of the artificial grass 1.

In the antistatic artificial grass of the first embodiment, after the carbon fibers 8 are bonded, the tip portion of the leaf 4 is bent by heating. However, depending on the length and arrangement of the leaf 4, As shown in FIG. 3, it is also possible to use the leaf-shaped body 4 as an antistatic artificial turf in a linear state. When the density of the leaf-shaped bodies 4 is low and there is a gap between the leaf-shaped bodies 4 even if the tip portion of the leaf-shaped bodies 4 is bent, the leaf-shaped bodies 4 are dispersed before the carbon fibers 8 are spray-bonded. It is also possible to heat and bend the tip portion of the carbon fiber 8 and then sprinkle the carbon fibers 8 from the side of the leaf-shaped body 4 and bond them with an adhesive.

Although the through holes 3 are provided in the base 2 to form a lattice shape, the base 2 may be formed into a non-hole plate shape. If the base 2 is made non-perforated, the dispersed carbon fibers 8 will not pass through the base 2, so
Approximately 15 mm of carbon fiber 8 is made shorter, for example, 1
It is possible to shorten the length from 0 mm to about 3 mm, and it is easier to spray the carbon fibers 8. Although the artificial turf 1 of the first embodiment is formed in a rectangular shape, this artificial turf can be formed into a long continuous strip.

FIG. 4 shows a second embodiment of the present invention, which relates to the spreading and adhesion of conductive fibers to artificial turf. The artificial grass 1 of the second embodiment is made of polyethylene,
Through holes 3 are provided in the base 2 at intervals to form a net-like shape, and elongated leaf-shaped bodies 4 are erected integrally on one surface at intervals. Then, the tip portion of the leaf-shaped body 4 is heated and bent as described above. The structure of the other artificial turf 1 is the same as that of the first embodiment, and therefore the same reference numerals are given.

The artificial turf 1 is placed in a horizontal state with the leaves 4 thereof facing downward. With respect to the artificial turf 1, carbon fiber 8 having a length capable of passing through the through hole 3
Is dropped from the side of the supporting leg 5 as shown by the arrow, and is sprayed on almost the entire artificial turf 1. The scattered carbon fibers 8 pass through the through-holes 3 and are placed on the curved tip end portion of the leaf-shaped body 4 or are sandwiched between the leaf-shaped bodies 4 to form a leaf-like shape. Some of the body 4 has a locking shape at the middle portion in the lengthwise direction, and some of the leaves 4 pass between the curved front end portions of the body 4. Next, the adhesive 9 made of polyethylene, which is the same as that of the artificial grass 1, is dropped or sprayed from the side of the supporting leg 5 as shown by the arrow, and the carbon fiber 8 sprinkled with the adhesive 9 that has passed through the through holes 3 is removed. Adhere to the frond body 4. After the adhesive 9 is cured, the unbonded carbon fibers 8 are removed to obtain an antistatic artificial grass.

The antistatic artificial grass of the second embodiment has the carbon fiber 8 which has passed through the through hole 3 provided in the base 2,
The carbon fibers 8 are arranged in a dispersed manner in each leaf body 4 by, for example, supporting the tip end portion of each leaf body 4 which is bent in advance. The carbon fiber 8 is bonded to the leaf-shaped body 4 with the adhesive 9 that has passed through the through hole 3. Therefore, since most of the carbon fibers 8 can be arranged on the tip side of each leaf 4, it is possible to more efficiently attenuate the static electricity accumulated in the artificial grass 1 by the corona discharge generated from the carbon fibers 8. . Most of the adhesive 9 adheres to the surface side of the leaf 4 facing the base 2 and little or less adhesive 9 adheres to the exposed surface of the leaf 4, which improves the appearance. it can. In addition, when the leaf-shaped body 4 is stepped on with a footwear, the footwear or the like rarely comes into direct contact with the carbon fiber 8, so that the carbon fiber 8 is prevented from peeling from the leaf-shaped body 4. It is easy to do.

[0036]

As described above, the antistatic artificial turf of the present invention is, as described above, an artificial turf which is formed of plastic by elongating elongated foliar leaf-like bodies integrally on one side of a plate-shaped base. Conductive fibers cut to an appropriate length are scattered and adhered to the surface of the artificial turf with an adhesive in which the conductive fibers are scattered. Therefore, it is possible to efficiently arrange the conductive fibers to the artificial grass, it is possible to disperse the conductive fibers on the surface of the artificial grass, and the conductive fibers to the artificial grass. Can be efficiently adhered.

The antistatic artificial turf according to claim 1 is characterized in that the conductive fibers are dispersed from the surface side on which the fronds are erected,
Moreover, since the adhesive is sprayed, the sprayed conductive fibers relatively easily pass between the leaves, and most of the conductive fibers are arranged on the surface of the base of the artificial grass. Therefore, it is possible to firmly adhere to the surface of the artificial turf with an adhesive agent in which conductive fibers dispersed on the surface of the base are dispersed. Further, since the conductive fibers are adhered to the surface of the artificial turf with an adhesive, the conductive fibers may be peeled from the base or the fronds even if the fronds are stepped on with a footwear. Almost no static electricity accumulated in the artificial grass can be efficiently attenuated for a long period of time by corona discharge generated in the conductive fiber.

The antistatic artificial turf according to claim 2 is an artificial turf obtained by bending the distal end of the leaf-shaped body and passing through the through hole from the surface opposite to the surface on which the leaf-shaped body is erected. The conductive fibers and the adhesive. Therefore,
The conductive fibers that have passed through the through-holes are supported by the bent portion on the tip side of the leaf and are distributed and arranged in the leaf, so the corona discharge generated in the conductive fiber accumulates in the artificial grass. The generated static electricity can be attenuated more efficiently. Then, since the adhesive adheres to the surface of the leaf-shaped body facing the base to bond the conductive fiber, when the leaf-shaped body is stepped on with the footwear, the footwear or the like hardly contacts the conductive fiber. . Therefore, the conductive fibers are not likely to be peeled from the leaves, and the static electricity of the artificial grass can be attenuated for a long period of time. In addition, the amount of adhesive that adheres to the exposed surface of the leaf-shaped body decreases, and the appearance can be improved.
