Description

Geogrid textile {geogrid textile}

The present invention relates to a woven fabric paper for geogrid, and more particularly, in the construction of geogrid woven paper that is woven in a conventional loom, even when using the warp and weft in 3000 denier or more to increase the tension in the same direction as the warp It relates to a geogrid woven paper configured to not cut the ground yarn of 150 denier.

As is well known, the geogrid fabric is supplied with polyethylene yarn to warp and weft yarns in a conventional loom and weaves the ground yarn at the intersection where the warp and weft yarns interweave so that the warp and weft yarns are not separated from each other. It is used as geogrid by coating the textile paper with a coater.

Such geogrids are widely used when constructing reinforcement soil retaining walls with construction blocks, or when performing various civil works such as asphalt bottoms and soft ground reinforcement works.

The most important thing in the geogrid used for the above uses should be excellent durability.

In order to provide a durable geogrid as described above, of course, the tension of the geogrid fabric paper should be good.

By the way, when looking at the configuration of the conventional geogrid fabric paper, four or more inclined space to form a square space up, down, left, right, at least three strands of weft are arranged to cross each other to form a square space and the slope and weft cross The ground yarn is supplied to the point to weave the warp and weft, and when the next warp and the weft are arranged to cross each other, the ground yarn is supplied to the intersection where the warp and the weft intersect and the warp and the weft are intertwined.

In the geogrid fabric paper configured as described above, the ground yarn moves in the same direction as the slope along the slope, and the ground yarn is configured to weave the inclined strands.

In order to improve the durability of the geogrid fabric paper, if you use a thick thread of warp and weft yarn and the ground yarn uses a thin thread, when the ground yarn weaves the warp and weft yarn at the intersection of the warp and weft yarn, the warp and weft yarn The ground yarn is not cut because the tension balance of the is maintained.

By the way, when the ground yarn weaves only the inclined strands while moving in the same direction as the inclined strand along the inclined strand, the ground yarn having a relatively weak tension is cut because the inclined is thick and the ground yarn is narrow, so there is a limit to the thickness of the inclined and weft yarn. There was a limit to increase the durability of geogrid textile paper.

The present invention devised to solve the problems as described above, even when weaving geogrid fabric paper using a slope and weft with 3000 denier and ground yarn at 150 denier in the process of weaving geogrid fabric paper by a loom. It is an object of the present invention to provide a geogrid fabric paper by increasing the durability of the geogrid fabric paper by weaving the geogrid fabric paper consisting of warp and weft yarn with a thick thread so that the thin ground yarn is not cut.

Geogrid woven paper according to the present invention for achieving the above object, the inclined 10 and the weft yarn 20 is supplied at regular looms and arranged at intervals spaced up, down, left, right rectangular space 30 In the geogrid fabric, which is composed of the ground yarn 40 is woven so that the cross section (2) intersecting the warp 10 and the weft yarn 20 is separated,

The warp yarn 10 is supplied in more than 3000 denier four strands, the weft yarn 20 is supplied in more than 3000 denier three strands, the ground yarn 40 is supplied in 150 denier, the ground yarn 40 is Then, when moving to the intersection portion 2 where the warp yarn 10 and the weft yarn 20 intersect, the ground yarn tissue 41 is constituted by being separated from the warp yarn 10 and weaved between the ground yarns 40. It is characterized in that the configuration in which the ground yarn 40 weaves the intersection portion 2 where the inclination 10 and the weft yarn 20 intersect.

According to the geogrid fabric paper according to the present invention as described above, when the ground yarn moves in the same direction as the slope in the configuration of the geogrid fabric paper, the ground yarn is woven between the ground yarns irrespective of the slope. It is effective to weave geogrid textile paper without cutting it,

Since the ground yarns are not cut, both warp and weft yarns can be woven using thick yarns, thereby providing a durable geogrid fabric.

Both the warp yarns and the weft yarns use thick yarns, and the ground yarns are coated on geogrid fabrics that are interwoven with each other, thereby providing a durable geogrid.

Hereinafter, with reference to the accompanying drawings, the configuration of the geogrid fabric paper according to the present invention will be described in detail.

1 is a plan view showing the configuration of the geogrid fabric paper according to the present invention, Figure 2 is an exemplary view showing an enlarged geogrid fabric paper according to the present invention, Figure 3 is a perspective view showing a part of the geogrid fabric paper according to the invention fractured 4 is a perspective view showing the configuration of a geogrid according to the present invention.

Fabric paper for geogrid according to the present invention,

As weaving in a normal loom, the type of warp and weft ground yarn constituting the woven fabric paper 1 for geogrid is high strength polyethylene yarn.

The thickness of the yarn is inclined 10 and the weft 20 is 3000 denier or more, the ground yarn is composed of 150 denier.

Slope 10 and weft yarns to be supplied to the inclined 10 more than 3000 denier four strands as described above, and to supply the weft yarn 20 over 3000 denier three strands up, down, left, right. Placed at intervals between the upper, lower, left, and right at intervals between the (20), the intersection (2) where the warp yarns 10 and the weft yarns 20 intersect, the ground yarn 40 is inclined 10 Weave with a weft (20) is configured to prevent the inclination (10) and weft (20) to move,

Then, when the ground yarn 40 moves in the same direction as the inclined 10 to the intersection portion 2 where the inclined 10 and the weft 20 intersect, the ground yarn 40 is separated from the inclined 10 and the ground yarn 40 Ground yarn tissue 41 is composed of only one another weave with each other, and the ground yarn 41 is intertwined at the intersection portion 2 where the next slope and the weft intersect so that the slope 10 and the weft yarn 20 cannot move. The configuration is repeated.

As described above, the ground yarn 40 is separated from the inclination 10 except for the intersection portion 2 where the warp yarn 10 and the weft yarn 20 intersect and are interwoven with only the ground yarns 40, and thus the ground yarn tissue 41 is formed. Geogrid 50 is completed by coating the fabric paper for geogrid 1 configured in the coating machine. The coating of the textile paper 1 uses, for example, a resin such as polyvinyl chloride, acrylic, latex, rubber, or bitumen (US Pat. No. 5,091,247, Japanese Patent Application Laid-Open No. 9-100527, Japanese Patent Application Laid-Open No. 2-125038, Korea Patent Registration). 10-0324502).

The operation of the textile paper for geogrid according to the present invention configured as described above and the geogrid thereby.

First, the inclined 10 is supplied to more than 3000 denier four strands, the inclined 10 is supplied to the weft yarn 20 at three or more denier three strands, and the inclined 10 and the weft 20 are intersected with the ground yarn 40 of 150 denier. It consists of a configuration that weave the intersection (2) to move, and the slope (10) in the section in which the ground yarn 40 moves in the same direction as the inclination to the intersection (2) where the next slope and weft intersect. Separated from the ground yarns 40 only weaves each other is composed of the ground yarn organization (41).

Therefore, although there is a tension difference according to the thickness of the inclination 10 and the ground yarn 40, since weaving does not affect each other, it is possible to weave geogrid textile paper while preventing the ground yarn 40 from being cut during weaving. .

As described above, the warp yarn 10 and the weft yarn 20 are composed of more than 3000 denier and 150 denier ground yarns 40, and the ground yarns 40 are interwoven with each other in the section moving along the warp yarn 10. By constructing the tissue 41, it is possible to improve the durability of the geogrid fabric paper, it is possible to provide a geogrid 50 with maximum durability because the coating on the geogrid fabric paper with excellent durability as described above.
