DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an artificial turf widely used in golf courses, driving ranges, baseball fields, tennis courts and the like.

[0002]

2. Description of the Related Art Conventional artificial turf includes artificial turf made of synthetic resin in addition to Wilton-type artificial turf made of a woven fabric, artificial turf made of a knit made of Russell knit, artificial turf made of tufted woven fabric, and the like. There are those that are characteristic of pile yarn original yarn and twist yarn, differ in pile yarn height,
Those subjected to crimping are known. Among these known artificial turf, artificial turf of a type woven by a Wilton loom, as shown in FIG. 1, is woven by repeating a ground yarn and a tightening yarn starting from a pile yarn as viewed from the upper left side. The pile yarn is not laid around the pile yarn, so the pile yarn is shifted left and right when tension is applied during weaving, and the pile yarn is woven in a state inclined in the weaving direction. ing. Therefore, when looking at the artificial turf from the top, it looks like there is a linear gap in the direction of the weft,
The pile density also appeared to be rough, and the end faces of the pile yarn bundles were also uneven, so that processing was required to finish the pile neatly. Also, as described in quality, pile yarns are slopingly woven, so pile yarns are likely to fall down and promote the habit of piles when storing raw rolls, Since the thread pulling force of the pile yarn is also weak, there is a disadvantage that the material of the adhesive on the back side of the artificial turf has to be improved and the amount used has to be increased.

[0003]

SUMMARY OF THE INVENTION The present invention solves the problem of the weaving structure which occurs in artificial turf woven by a Wilton loom, and arranges fastening yarns on both sides around a pile yarn. This allows the pile yarn to stand upright, raises the nap, prevents the yarn from being pulled out, and fills the gap between the pile yarns even when the artificial grass is viewed from the top, improving the overall density and improving the tip of the pile yarn. By arranging the cut surfaces, the finishing work can be reduced, and the amount of adhesive applied to the back side of the artificial turf can be reduced to reduce the labor required for finishing the artificial turf raw fabric and improve the quality of the artificial turf.

[0004]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, in an artificial turf made of synthetic fibers such as nylon and vinyl chloride woven by a Wilton loom, a woven structure of pile yarn, tightening yarn and weft yarn is tightened. The pile yarn 3 is arranged next to the yarn 4 and the tightening yarn 6, the tightening yarn 6 and the tightening yarn 4 are provided from the pile yarn 3, and the
And an artificial lawn made by weaving the pile yarn 3 followed by the tightening yarn 4 and the tightening yarn 6 in one process, and repeating the same process with the pile yarn 3 as the center.

[0005]

According to the structure of a conventional artificial turf woven by a Wilton loom, two ground yarns enter below the pile yarns, and then a fastening yarn that crosses up and down is provided and the pile yarns are arranged next to each other. By eliminating the configuration of two ground yarns overlapping the pattern, the tension was evenly applied, and tightening yarns vertically intersecting were arranged on both sides of the pile yarn, so that the side U-shaped pile yarn was sandwiched. In this state, the pile yarns are erected and the nap-raising property is enhanced, so that the group of U-shaped pile yarns does not open halfway outward or shift back and forth or right and left when the artificial turf is viewed from above. In addition, since the space occupied by the two ground yarns that overlaps is lost in the configuration, the pile yarn is woven in a state where the tightening yarn and the weft yarn that intersect vertically on both sides are centered around the pile yarn, and all the pile yarns are It is firmly tightened by the action of the tightening thread.
In addition, the roots of the pile groups that are erected in a straight line are also bundled by the action of the tightening thread, and the pile thread is opened upward, and the gap between the pile threads is dense, so that the gap in the lateral direction is not visible. Will be.

An embodiment according to the claims will now be described with reference to the drawings. An artificial turf woven by a Wilton loom, wherein the pile yarn 3 is made of synthetic fiber made of vinyl chloride and polyethylene resin, and the fastening yarn 4, the fastening yarn 6 and the weft 7 serving as the base fabric of the artificial turf A are polypropylene. Fiber is used, and the length of the pile yarn 3 is cut to 13 to 15 mm from the base cloth. As shown in FIG. 2 which is developed in a plane, the weaving structure is such that the tightening yarn 4 and the tightening yarn 6 are entangled with the weft 7 so as to intersect vertically, and weaving is performed next to the tightening yarn 4 and the tightening yarn 6. A U-shaped pile yarn 3 is arranged, and a tightening yarn 6 and a tightening yarn 4 that support the pile yarn 3 in a straight line are weaved around a weft 7 so as to be interwoven up and down and arranged. The pile yarns 3 are woven by providing the tightening yarns 4, and the number of the tightening yarns provided between the respective pile yarns 3 is set to four and woven. Therefore, the two left-hand tightening yarns and the two right-hand tightening yarns center on the pile yarn 3 and cross each other up and down, so that the pile yarn 3 is firmly supported.
Lateral misalignment between the wefts 7 is eliminated, so that the U-shaped pile yarns 3 do not open outward, and the pile yarns 3 are erected to improve the napping property. In addition, since the weaving of the two ground yarns 8 with respect to the weft 7 is changed to the same two yarns as in the conventional design shown in FIG. 1, there is no displacement between the weft and the yarn at the time of tension. The periphery of the insertion portion 5 of the yarn 3 is woven in a close contact state to enhance the effect of preventing the pile yarn 3 from coming off, and a pile gap portion 9 generated in the lateral direction between the pile groups 2.
Disappears, and the pile yarns that are clustered when viewed from the top have a uniform surface.

[0007] As described above, the artificial turf A repeatedly woven around the pile yarns 3 does not shift the pile yarns left and right even when tension is applied, and the pile yarns do not incline in the weaving direction. Even if the turf is wound, the pile yarn will not fall down sideways, eliminating the need to process the pile yarn upright, and applying adhesive to the entire back surface of the artificial grass A so that the pile yarn does not come off due to the impact during use. since woven rigidly clamped in a state where tightening yarns and weft intersecting vertically on both sides of the pile yarn is in close contact, the coating amount per m ² also becomes possible to reduce about 20%, finish the entire raw work Even in time, the interval between the pile yarns is also increased by the action of the two tightening yarns, the pile yarns are opened upward, eliminating the pile gap, and the U-shaped pile yarns are cut neatly in a state where the height is cut equally to the left and right. From pa The work time for adjusting the height of the thread can also be reduced.

For applications such as golf hitting mats, there are also products woven with different pile yarn colors. For example, the right half has a rough color and the left half has a fairway. Products such as color, mats such as zebra or stripes, or white lines in the center of the practice mat to check the impact direction are different colors due to the pile thread being upright Since the colors of the pile yarns at the boundary are clearly aligned in a straight line, an effect of neat finishing can be obtained without any trouble of processing.

[0009]

The artificial lawn described in the claims has the following effects by improving the structure of pile yarns, tightening yarns and weft yarns woven by a Wilton loom from the operation shown in the embodiment. Is obtained. That is, 2 below the pile yarn
There are two ground yarns, and then the weaving arrangement consisting of two upper and lower intersecting yarns is changed, and four upper and lower intersecting yarns are interposed between the pile yarns. , The tension is evenly applied, and the action of the tightening yarn sandwiching the pile yarns enhances the pile-up property of the pile group and eliminates the pile gap, and the left and right height of the U-shaped pile yarn is reduced. Since the pile yarn bundles are woven in a state of being cut to substantially the same dimensions, the pile yarn bundles are aligned in an upright state, and the end surfaces thereof are also aligned, so that the finishing process can be shortened and a high quality product can be obtained. In addition, the tightening yarn and the weft that intersect up and down around the pile yarn are tightly woven, and the root of the pile yarn bundle that is standing up straight is also firmly tightened, the yarn pulling force increases, and the application of the adhesive on the back side of the artificial grass The present invention provides a durable and beautifully woven artificial turf that is less likely to cause the pile yarn to fall off the base cloth with a slight impact even if it decreases.
