(16) In an embodiment, an interlaced geotextile fabric (may be interchangeably referred to as geotextile, fabric, or interlaced fabric) is disclosed. This geotextile fabric may be used for various applications, including separation, filtration, drainage, reinforcement, stabilization, and protection.

(17) The present disclosure provides a solution to the issues encountered by traditional geotextiles. The solution involves modifying factors such as weave and/or yarn density, yarn type, and weaving pattern in the geotextile fabric to enhance the tensile strength and flow behavior of geotextile fabric.

(18) The present disclosure relates to an interlaced geotextile fabric. The geotextile fabric comprises at least one set of a warp yarn comprising a monofilament yarn. Herein, the warp yarn contributes to the structural properties and performance characteristics of the fabric, making warp yarn a key factor in various civil engineering and protection applications. Further, the monofilament yarn of the warp yarn is in a range of about 90-100 weight % of the total weight of the warp yarn.

(19) In addition to warp yarn, the interlaced geotextile fabric comprises at least one set of a weft yarn. More preferably, the weft yarn comprises a first set of a weft yarn and a second set of a weft yarn. Here, the terms the first set of the weft yarn and the second set of the weft yarn do not specify a sequence and can be used interchangeably.

(20) Several combinations of the weft yarns can be interlaced with warp yarn to attain the desirable efficiency of the weaving and the quality of the finished fabric. Herein, the interlaced geotextile fabric comprising a set of the warp yarn with two sets of the weft yarn is preferred. Furthermore, the weft yarn may comprise at least one of a fibrillated tape yarn, a monofilament yarn, or a combination.

(21) In an alternative embodiment, the interlaced geotextile may comprise the set of the monofilament warp yarn, the first set of a weft yarn comprising the fibrillated tape yarn (interchangeably referred to as weft yarn 1), and the second set of the weft yarn comprising the monofilament yarn (interchangeably referred to as weft yarn 2).

(22) In an alternative embodiment, the interlaced geotextile may comprise the set of the monofilament warp yarn, the first set of the weft yarn comprising the monofilament yarn, and the second set of the weft yarn comprising the fibrillated tape yarn.

(23) In an alternative embodiment, the interlaced geotextile may comprise one set of the monofilament warp yarn, a first set of the weft yarn comprising the monofilament yarn, and a second set of the weft yarn comprising a combination of fibrillated tape yarn and monofilament yarn.

(24) In a preferred embodiment, the interlaced geotextile further may comprise the set of the monofilament warp yarn, the first set of the weft yarn comprising the fibrillated tape yarn (weft yarn 1), and the second set of the weft yarn comprising a combination of the fibrillated tape yarn (weft yarn 1) and the monofilament yarn (weft yarn 2) in a ratio of 1-4:1, more preferably 3:1.

(25) Herein, two sets of the weft yarn are preferred in the geotextile fabric as two distinct types of weft yarns facilitate a porous structure that yields high flow rates and low AOS. Additionally, the physical difference in size and texture of these two yarns makes a distinct porous structure when set in a specific repetition and yields desired low AOS values with high permittivity.

(26) Herein, each set of the weft yarn is interwoven with at least one set of the warp yarn to obtain the interlaced geotextile fabric. The interlaced geotextile fabric may be interwoven into several types of patterns which include but are not limited to a twill weave, plain weave, satin weave and, more preferably twill weave.

(27) The twill weave is a fundamental textile weave distinguished by its characteristic diagonal rib pattern, which enhances the strength and flexibility of fabrics. Unlike plain weaves, where the warp yarn and weft yarn cross each other alternately, twill weave involves a staggered over-and-under pattern, resulting in a distinct diagonal texture. The specific pattern of over-and-under passes can vary, leading to different types of twill weaves such as 11, 22, 33, 44, and others.

(28) In the present disclosure, a 44 twill weave is preferred with a repeat of 4 warp and 4 weft threads. These twill weaves can be woven in variations which include regular, unbalanced, reverse, or double twill

(29) In an embodiment, the unbalanced 44 twill is preferred which includes the weave being uneven and unbalanced, with a pattern that is not limited to a 3 over and 1 under pattern, or vice versa, or a 4 over and 4 under pattern, or vice versa. The unbalanced twill creates a more pronounced diagonal line and results in a fabric that can have different textures or thicknesses on each side. Thus, the twill pattern of the interlaced geotextile significantly impacts the performance and properties such as coefficient of friction, AOS, and flow rate of water of the geotextile fabric.

(30) In another embodiment, the monofilament yarn of the warp yarn is in a range of about 90-100 weight % of the total weight of the warp yarn. Whereas the monofilament yarn of the weft yarn, specifically the second set of the weft yarn, is in a range of about 1-5 weight % of the total weight of the second set of the weft yarn.

(31) In a related embodiment, the fibrillated tape yarn of the first set of the weft yarn is in a range of about 90-100 weight % of the total weight of the first set of the weft yarn. Likewise, the fibrillated tape yarn of the second set of the weft yarn is in a range of about 90-98 weight % of the total weight of the second set of the weft yarn.

(32) In another embodiment, the monofilament yarn and fibrillated tape yarn are selected from at least one polypropylene, polyester, polyethylene, nylon, and combinations thereof. More preferably, the monofilament yarn and fibrillated tape yarn are polypropylene (PP) yarn.

(33) Herein, PP fibrillated yarns are preferably selected as they facilitate resistance to environmental factors such as UV radiation, chemicals, and biological degradation. Additionally, the PP fibrillated yarns are opted out as a geotextile material to yield a high tensile modulus and facilitate a higher rate of water flow through the manufactured fabric.

(34) Similarly, the monofilament yarn is made up of PP for the same inherent properties and additionally to impart a porous structure to the geotextile fabric which facilitates a high-water flow rate at low apparent opening sizes. Thus, polypropylene as the choice of material for weft yarns uplifts the geotextile's resistance to chemical and environmental degradation, UV resistance, and overall durability. Furthermore, the warp yarn and weft yarn comprise 90-95 wt. % polypropylene of the total weight of the yarn.

(35) In a preferred embodiment, the interlaced geotextile fabric comprises at least one set of warp yarn comprising the polypropylene monofilament tape yarn, the first set of a weft yarn comprising the polypropylene fibrillated tape yarn, and a second set of a weft yarn comprising a combination of polypropylene fibrillated tape yarn and polypropylene monofilament yarn in a ratio of 3:1.

(36) In addition to polypropylene, the warp yarn and the weft yarn of the interlaced geotextile fabric may further comprise at least one additive selected from calcium carbonate, coloring component, linear low-density polyethylene (LLDPE), high-density polyethylene (HDPE), and UV stabilizer. The additives are added in weight percent in the range of 4 to 10% of the total weight of the fabric admixture.

(37) In one aspect of the disclosure, the warp yarn and second set of the weft yarn may comprise a composition of the coloring component, high-density polyethylene (HDPE) in the range of 2-4%, and UV stabilizer in the range of 1-2%, more preferably in the range of 1.2%. Similarly, the first set of the weft yarn may comprise a composition of calcium carbonate and linear low-density polyethylene (LLDPE) in a range of 1-2%, coloring component in a range of 3-5%, and UV stabilizer in a range of 0.1-0.5%. Herein, the LLDPE aids in increasing the processability and strength of the yarn.

(38) In a different aspect of the disclosure, the first set of the weft yarn and the second set of the weft yarn do not incorporate any LLDPE and HDPE additives.

(39) Moreover, each set of the weft yarn is woven in floats of the warp yarn. More particularly, the weft yarns are woven in floats of the warp yarns and these floats can either be up or down relative to the weft position creating an interlaced fabric structure.

(40) These alternate floats in the fabric comprise the first set of the weft yarn containing polypropylene fibrillated tape yarn and the second set of the weft yarn containing a mix of polypropylene monofilament yarn and polypropylene fibrillated tape yarn makes a unique ribbed fabric surface. Consequently, the interlaced geotextile fabric exhibits an exceptional interaction coefficient with soil, emphasizing its efficacy in relevant applications due to its ribbed surface structure.

(41) The direction of weaving in the fabric includes warp direction and weft direction. Different machines and apparatus are employed to weave the fabric in a machine direction or cross-machine direction.

(42) Furthermore, a set of the weft yarn is woven in the same direction at an interval. Herein, the interval defines a pattern of weaving the multiple sets of the weft yarn. More preferably, the interval defines a pattern of weaving the two sets of the weft yarn in the interlaced geotextile.

(43) In another embodiment, the first set of the weft yarn and the second set of the weft yarn are interwoven in the same direction at an interval from fourth to tenth pick interweaves. More preferably, the first set of the weft yarn and the second set of the weft yarn are interwoven in the same direction at an interval of 8 pick interweaves.

(44) In a related embodiment, the geotextile fabric having at least two of each first to seventh weft pick is the first set of weft yarn, and at least one of each fourth to tenth weft pick is the second set of weft yarn. A ratio of weft pick of the first set of weft yarn to the second set of weft yarn is 1:1. The first set of the weft yarn is fibrillated tape weft yarn, and the second set of the weft yarn is a combination of .sup.th fibrillated tape yarn and .sup.th monofilament yarn.

(45) In a related embodiment, the geotextile fabric having at least two of each first to seventh weft pick is the first set of weft yarn, and at least one of each fourth to tenth weft pick is the second set of weft yarn. Specifically, a first to fourth weft pick is the first set of weft yarn and every fifth to eighth weft pick is the second set of the weft yarn. More specifically, a first to fourth weft pick is the first set of fibrillated tape weft yarn and every fifth to eighth weft pick is the second set of the weft yarn comprising a combination of .sup.th fibrillated tape yarn and .sup.th monofilament yarn.

(46) Referring to FIG. 2, a detailed schematic view of the interlaced geotextile fabric is illustrated. The geotextile fabric preferably comprises picks 1-4 representing the first set of the weft yarn and picks 4-8 representing the second set of weft yarns. Also, it can be noted that pick 1-4 of the first set of the weft yarn and pick 5-7 of the second set of the weft yarn is fibrillated tape yarn and pick 8 of the second set of the weft yarn is monofilament yarn.

(47) In another embodiment, the interlaced yarn comprises a round cross-section of the monofilament yarn of the warp yarn in a range of about 1300-1500 denier, and more preferably 1350 to 1450 denier. Similarly, the interlaced yarn comprises a rectangular cross-section, and honeycomb fibrillations of the fibrillated tape yarn of the weft yarn are in a range of about 5000-7000 denier.

(48) In a related embodiment, the interlaced geotextile fabric comprising a rectangular cross-section of the monofilament yarn of the weft yarn is in the range of about 600 to 800 denier, more preferably 650-750 denier.

(49) In another embodiment, the interlaced geotextile fabric comprises a density in the warp direction in a range of about 20 to 35 yarns/inch, more preferably 30 yarns/inch, and a density in the weft direction in a range of about 8 to 20 yarns/inch, more preferably 10-15 yarns/inch, more preferably, 14 yarns/inch.

(50) The distinct physical characteristics, size, density, and denier disparity between the first set of the weft yarn and the second set of the weft yarn, coupled with their special arrangement within the fabric, create a unique porous fabric structure. This structure enables significant water flow rates and enhances particle retention. Thus, the interlaced geotextile fabric prepared as per the present disclosure demonstrates several improved properties such as water flow rate and interaction coefficient.

(75) Further, the properties such as tensile strength, coefficient of interaction, water flow rate, and apparent opening size of the geotextile fabrics A, B, C, D, and E obtained by examples 1, 2, 3, 4 and 5 respectively were compared (results provided in table 1).

(76) TABLE-US-00001 TABLE 1 Comparison of the interlaced geotextile fabric with existing geotextile fabric Geotextile Geotextile Geotextile Geotextile Geotextile fabric A fabric B fabric C fabric D fabric E Warp yarn and weft 21 8 30 9.7 30 13.2 30 12.7 30 13.7 yarn density (number of yarns per inch or picks per inch) Dimensions of yarn 0.95 mm 0.90 mm 1.1 mm 0.50 mm 0.50 mm (warp weft) 13 mm 13 mm 13 mm 7 mm in 7 mm in width/ width/ 0.80 mm 0.80 mm in diameter in diameter Tensile Strength at 7 KN/m 10.5 KN/ 14 KN/m 8.8 KN/m 8.8 KN/m 2% elongation 8.6 KN/m 15 KN/m 21.9 KN/m 14.9 KN/m 14.9 KN/m (MD AND XMD) Tensile Strength at 38 KN/m 22 KN/m 35 KN/m 26 KN/m 26 KN/m 5% elongation 36 KN/m 23 KN/m 44 KN/m 33 KN/m 33 KN/m (MD AND XMD) Water flow rate 0.60 0.80 0.40 0.90 0.90 in sec.sup.1 AOS in micron 600 600 600 425 425 Coefficient of >.90 >.90 interaction Weave design 1 1 3 1 4 4 4 4 4 4 Weave pattern Plain Twill Regular Unbalanced Unbalanced twill twill twill Interval 2 picks 4 picks 8 picks 8 picks 8 picks *Herein, mD: machine direction (lengthwise); XMD: cross-machine direction (horizontal lengthwise)

(77) Thus, the table highlights the enhanced properties of the geotextile fabric D and E as compared to comparative Examples of geotextile fabrics A, B & C. Thus, it can be concluded that the geotextile fabric D and E comprising a warp yarn, and two types of weft yarns (weft yarn 1, and weft yarn 2) have better pore sizes of less than 425 microns and high-yielding permittivity greater than 0.9 sec.sup.1.

(78) Based on the data presented in FIG. 3, it is evident that geotextile fabric D demonstrates enhanced flow rates even at lower Apparent Opening Size (AOS) when compared to geotextile fabrics A, B, and C.

(79) Additionally, it is worth noting that geotextile fabric E exhibits comparable results to geotextile fabric D, suggesting that construction is the critical attribute that is helping us to achieve hydraulic properties. Thus, the enhanced properties are the result of a synergistic effect stemming from one or more components such as weaving pattern, type of weft yarn, denier, and density of yarn, rather than the presence of additives.

(80) Thus, it can be concluded that attributing factors such as the usage of two sets of the weft yarn and the arrangement of every eighth pick being of different type and dimensions of the weft yarn along with the weave pattern of unbalanced twill contributes to the improved soil retention and high-yielding permittivity.

(81) The improved properties achieved by the claimed interlaced geotextile fabric include, Elevate the fabric's overall tensile strength, reinforcing its durability and robustness. Better coefficient of friction when in contact with soil. High water flow and particle retention coupled with excellent interaction coefficient. High-yielding permittivity

(82) This claimed interlaced geotextile fabric on application in roadway construction and ground stabilization offers reinforcement, stabilization, separation, and drainage performance when used on soft soil.
