Interlaced geotextile fabric
An interlaced geotextile fabric obtained by inter-weaving at least one set of a warp yarn and at least one set of a weft yarn. More specifically, the interlaced geotextile fabric has an unbalanced twill weave pattern, which is suitably used for soil stabilization. The distinct physical characteristics, size, and denier disparity between weft yarns of the fabric promote hydraulic properties and minimize apparent opening size while offering a stable and durable product upon installation.
1 . An interlaced geotextile fabric, comprises:
at least one set of a warp yarn comprising a monofilament yarn; and
at least one set of a weft yarn comprising at least one of a fibrillated tape yarn, the monofilament yarn, or a combination thereof,
wherein each set of the weft yarn is woven in a same direction at an interval,
wherein the fabric has a permittivity of at least 0.7-0.9 sec −1 ;
an opening size of at least 400-450 microns; and
an interaction coefficient of at least 0.7-1.0.
2 . The interlaced geotextile fabric as claimed in claim 1 , wherein at least one set of the weft yarn, comprises:
a first set of the weft yarn comprising the fibrillated tape yarn;
a second set of the weft yarn comprising the monofilament yarn and fibrillated tape yarn; or a combination.
3 . The interlaced geotextile fabric as claimed in claim 1 , wherein the monofilament yarn and the fibrillated tape yarn are selected from at least one polypropylene, polyester, polyethylene, nylon, and combination.
4 . The interlaced geotextile fabric as claimed in claim 1 , wherein the monofilament yarn of the warp yarn is in a range of about 90-100 weight % of total weight of the warp yarn.
5 . The interlaced geotextile fabric as claimed in claim 2 , wherein the fibrillated tape yarn of the first set of the weft yarn is in a range of about 90-100 weight % of total weight of the first set of the weft yarn.
6 . The interlaced geotextile fabric as claimed in claim 2 , wherein the second set of the weft yarn comprises,
the monofilament yarn in a range of about 1-5 weight % of total weight of the second set of the weft yarn; and
the fibrillated tape yarn in a range of about 90-98 weight % of total weight of the second set of the weft yarn.
7 . The interlaced geotextile fabric as claimed in claim 1 , wherein a round cross-section of the monofilament yarn of the warp yarn is in a range of about 1300 to 1500 denier.
8 . The interlaced geotextile fabric as claimed in claim 1 , wherein the fibrillated tape yarn of the weft yarn has a rectangular cross-section and honeycomb fibrillations, and wherein the fibrillated tape yarn has a linear density in a range of about 5000-7000 denier.
9 . The interlaced geotextile fabric as claimed in claim 1 , wherein the monofilament yarn of the weft yarn has a rectangular cross-section, and wherein the monofilament yarn has a linear density in a range of about 600 to 800 denier.
10 . The interlaced geotextile fabric as claimed in claim 1 , wherein at least one of the warp yarn and the weft yarn further comprises at least one additive selected from calcium carbonate, color, linear low density polyethylene (LLDPE), high density polyethylene (HDPE), and UV stabilizer.
11 . The interlaced geotextile fabric as claimed in claim 1 , wherein each set of the weft yarn is interwoven with the at least one set of the warp yarn such that the interlaced geotextile fabric has a twill weave pattern.
12 . The interlaced geotextile fabric as claimed in claim 1 , wherein the first set of the weft yarn and the second set of the weft yarn are interwoven in same direction at an interval from fourth to tenth pick interweave.
13 . The interlaced geotextile fabric as claimed in claim 1 , wherein the first set of the weft yarn and the second set of the weft yarn are interwoven in same direction at an interval from an eighth pick interweave.
14 . The interlaced geotextile fabric as claimed in claim 12 , wherein at least two of each first to seventh weft pick are the first set of the weft yarn, and at least two of each fourth to tenth weft pick is the second set of the weft yarn.
15 . The interlaced geotextile fabric as claimed in claim 13 , wherein the first to fourth picks are the first set of the weft yarn, and the fifth to eighth picks are from the second set of the weft yarn.
16 . The interlaced geotextile fabric as claimed in claim 1 , wherein each set of the weft yarn is woven in floats of the at least one set of the warp yarn.
17 . The interlaced geotextile fabric as claimed in claim 1 , wherein weaving of the fabric is extended in a direction selected from a warp direction and/or a weft direction.
18 . The interlaced geotextile fabric as claimed in claim 1 , has a warp yarn density in the warp direction is in a range of about 20 to 35 yarns/inch; and wherein a weft yarn density in the weft direction is in a range of about 8 to 20 yarns/inch.
19 . The interlaced geotextile fabric as claimed in claim 1 , comprises:
