Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a rug particularly useful as an artificial lawn for collecting balls in a golf driving range.
[0002]
[Prior art]
Conventionally, golf practice grounds have been used to maintain beautiful green conditions all year round, and artificial lawn rugs have been widely used to save natural grass conservation costs (maintenance costs). Installation of an automatic ball collection facility that collects golf balls in peripheral grooves and collects them while washing them with a water stream is advancing.
[0003]
As conventional rugs used in this facility, those shown in FIGS. 5 to 11 are known. The rug C shown in FIG. 5 and FIG. 6 knits a warp stitch 24 while passing a filament yarn 23 such as polypropylene through a base fabric 22 made of a nonwoven fabric reinforced with a flat yarn fabric lining 21 having a rough structure. The pile yarn is fixed by the coating layer 25 on the back surface.
[0004]
The rug D shown in FIGS. 7 and 8 is formed by simultaneously knitting the ground texture 26 and the three-dimensional hexagonal Raschel mesh 27 by a double Raschel knitting machine using a filament yarn such as polypropylene.
[0005]
The rug E shown in FIGS. 9 and 10 is composed of a non-woven fabric layer 29 obtained by needle punching a fiber web on a base fabric 28, and the back surface is reinforced with a resin film layer 30.
[0006]
A rug F shown in FIG. 11 is obtained by forming a loop pile 33 on a base fabric 31 made of a flat filament fabric of polypropylene by using a tufted machine for making a tufted carpet with warp pile yarn 32, and applying a latex layer 34 on the back surface. is there.
[0007]
However, in the rug C, since the base fabric 22 is a non-woven fabric, it is easy to absorb water and becomes wet for a long time, and since it is outdoors, black mold is generated and the appearance is unsightly. Since 22 is a thin ground reinforced with a flat yarn fabric, there are drawbacks such as being easily damaged by the impact of a golf ball.
[0008]
In the rug D, since the entire structure is a stitch structure and the structure is rough and the flowing water immediately permeates to the back surface, it takes time to clean and collect the balls, requires an expensive double-raschel knitting machine, and has low productivity. Therefore, there are drawbacks such as being expensive.
[0009]
The rug E has a non-woven fabric structure as a whole, absorbs water and is wet for a long time, and the ball may be colored green, and further, black mold tends to occur.
[0010]
In the rug F, since the base fabric 31 is thin, the durability is poor and the ball is easily damaged by the impact of the ball, the loop pile 33 is easy to sag, the surface is uneven during the loop creation, and the rolling of the ball on the surface is poor. There are disadvantages such as low ball collection performance.
[0011]
[Problems to be solved by the invention]
Therefore, the object of the present invention is to reduce the water absorption and to prevent black mold from being generated. The pile has the required durability and cushioning properties and can maintain a smooth pile surface over a long period of time. flowing water flows to the surface without permeability Te is to provide an artificial lawn coverings that can be performed with high efficiency washing and recovery of the ball.
[0012]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the artificial lawn rug of the present invention comprises a warp pile made of water-repellent filament yarn, a warp yarn made of a flat water-repellent filament bundle, and a weft core made of a water-repellent filament yarn. The yarn and the weft yarn made of water-repellent filament yarn were interlaced, and the ground texture was woven by Wilton, and at the same time, a loop pile was formed in a pattern, and the weft core yarn was inserted into the loop pile. In addition, the length of the pile is 1 . It is good to set it as 0 mm-5.0 mm. Furthermore, a coating layer or a foam layer can be provided on the back surface of the ground structure .
[0013]
[Action]
The artificial lawn rug according to the present invention is a filament yarn that has a large durability and is supported by a ground yarn of warp and weft crossed with piles of a required pile length, and has a large durability. Because it is made of woven fabric, it absorbs water and does not get wet, and it can make the ground structure dense, making it difficult for water to permeate through it, guiding running water to the surface of the pile, and efficient cleaning and recovery of balls. You can do it well. Further, when the pile length is 1.0 mm to 5.0 mm and the reinforcing core yarn is inserted into the loop, the cushioning property is increased, and the pile surface has no unevenness and can maintain a uniform plane for a long time.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to FIGS.
[0015]
As shown in FIG. 1 and FIG. 2, the artificial lawn rug A is a lightweight, flame-retardant and inexpensive polyolefin-based synthetic fiber, ie, a polypropylene fiber (PP fiber) monofilament bulky processed yarn. Four warp pile yarns 1, 1, 1, 1 are bundled, and warp loop piles 2 are woven in a staggered pattern by a Wilton loom.
[0016]
The ground structure 3 is composed of warp yarns 4 and 4 made of flat filament bundles of polypropylene fibers, two weft fabrics 5 and 5 made of round filament bundles of polypropylene fibers, and the pile yarn 1 for cross weaving. Has been.
[0017]
Further, two reinforcing weft yarns 6 made of polypropylene filament round filament yarn are inserted into the loop pile 2. The weft core yarns 6 are alternately woven during weaving in a zigzag manner in the loop piles 2 arranged in a staggered pattern. For this reason, the loop pile 2 can be expected to have a highly efficient ball collection effect by preventing deformation against pressurization and equalizing the height of each loop pile, and smooth rolling of the balls.
[0018]
The rug A is provided with a black paint layer 7 on the back surface, the texture is appropriately blocked to restrict water permeability, and the water flow on the top surface of the pile is improved so that the balls can be washed and recovered. It is designed so that it can be performed with high efficiency, and the weather resistance and durability are improved.
[0019]
The warp pile yarn 1 is suitably used in the range of 1,000 denier to 10,000 denier.
[0020]
The loop pile 2 has a height from the upper surface of the ground structure 3, that is, a pile length l, in a range of 0.5 mm to 10.0 mm, preferably 1.0 mm to 5.0 mm. For this pile, the pile length l can be appropriately selected according to the use, the thickness of the pile yarn, the density of the pile, and the like. The pile length l can be easily changed by adjusting the pile forming wire in the Wilton loom.
[0021]
In the rug A, since the loop pile 2 is formed from a bulky processed yarn of a filament, it has a fluffy feel and a high-class feeling, and has elasticity, absorbs the impact force of the ball, and is scattered wastefully. Since each yarn such as pile yarn, ground yarn, and core yarn is formed from a filament yarn having hydrophobic water repellency, it does not become wet for a long time even when submerged. The ball is not colored.
[0022]
In addition, the ground structure 3 can select the durability, the degree of water permeability, and the like by appropriately adjusting the weave density.
[0023]
3 and 4 show another embodiment. As shown in the figure, the rug B is composed of two warpile yarns 8 and 8 made of monofilaments of monofilaments of polypropylene fibers, warp yarns 9 and 9 made of flat filament bundles of polypropylene fibers, and a loop pile 10. When the weft core yarn 11 made of a round filament yarn inserted into the yarn and the weft yarn 12 made of a flat filament bundle of polypropylene fibers are interlaced, and the loop pile 10 is formed in a horizontal stripe pattern by a Wilton loom. At the same time, a solid ground structure 13 is woven and a coating layer 14 is applied to the back surface.
[0024]
This rug B is suitable for the loop pile 10 having a relatively small size and pile density.
[0025]
In addition to polypropylene, that is, polyolefin fibers, the rug according to the present invention can be appropriately selected from polyamide-based, polyester-based, polyacryl-based, etc., depending on the application. The yarn is not limited to the bulky processed yarn of the filament, and a film-type filament, a multifilament, a monofilament and the like can be appropriately selected, and a denier having an appropriate thickness can be selected.
[0026]
In addition to the loop pile as described above, the pile shape can be cut and loop pile or full cut pile, and the pattern is also a houndstooth checkered pattern, a horizontal stripe pattern, various stripe patterns, and a dot pattern pattern. Etc. can be selected as appropriate, and the unevenness of the pattern can be expressed freely.
[0027]
A rug using monofilament yarn or multifilament yarn for the pile has the advantage that the pile surface is very smooth, the ball is easy to roll, and the recess for collecting balls may be shallow.
[0028]
Furthermore, in addition to applying the coating layer on the back surface of the ground structure as described above, a foam layer can be provided to give cushioning properties and non-slip properties.
[0029]
The rug of the present invention is used for collecting golf balls at a golf driving range, and conventionally used artificial lawns such as veranda mats for hotels, condominiums, passage mats, entrance mats, car mats for cars, and artificial turf for various stadiums. Can be used.
[0030]
【The invention's effect】
According to the present invention, as described above, the pile yarn and the ground yarn are cross-woven by the Wilton loom to simultaneously produce the pile and the ground texture, and the whole is composed of the filament yarn having hydrophobic water repellency. In addition, because it is a woven fabric structure, it will not absorb water for a long time and will not cause black mold, etc. Can be implemented efficiently.
[0031]
Furthermore, when the pile length is selected and the core thread is inserted, the cushioning property is increased and the ball can be prevented from being splattered, the pressure resistance is increased, and the pile surface has a good flatness and a uniform flat state over a long period of time. The ball can be maintained and cleaned and collected more efficiently.
