Description

TECHNICAL FIELD The present disclosure relates to a field of geotextile fabric. More specifically, the present disclosure relates to an interlaced geotextile fabric comprising warp yarn and weft yarn interlaced with each other in a specific weave pattern. BACKGROUND Geotextiles represent a class of synthetic materials designed to provide various engineering functions within civil and environmental projects. These versatile textiles are manufactured from synthetic fibers, such as polyester or polypropylene, and are engineered to withstand the rigors of construction, erosion control, filtration, and drainage applications. Unlike traditional textiles, geotextiles are specifically engineered to possess high tensile strength, durability, and resistance to environmental factors such as UV radiation, chemicals, and biological degradation. Additionally, the geotextile fabric serves as an effective barrier against the intrusion of fine particles while allowing water to pass through, facilitating drainage and preventing the buildup of hydrostatic pressure. Therefore, geotextiles are highly preferred for a wide range of applications, including road construction, embankment stabilization, landfills, coastal protection, agricultural engineering, and environmental projects. The adoption of geotextiles has revolutionized the field of civil engineering, offering sustainable and cost-effective solutions to complex challenges by providing superior soil reinforcement, filtration, and drainage capabilities, geotextiles contribute to the longevity and stability of infrastructure while minimizing environmental impact. Moreover, in light of the rising demand for sustainable construction practices to ensure durability, efficiency, and environmental responsibility, developing suitable geotextiles is poised to play an increasingly vital role in modern engineering projects. Geotextile, an exclusively woven web which can be an interlaced woven or non-woven web of polypropylene or polyester yarns in varied orientations, plays a crucial role in civil engineering applications. Numerous studies have demonstrated that the orientation of yarns significantly impacts the physical and mechanical properties of woven geotextiles. Geotextiles featuring appropriate yarn orientation exhibit enhanced durability, high tensile strength, and minimal elongation, making them favored choices for diverse engineering needs. In the state of the art, there are several extensive studies on the effect of the depth, length, and vertical distance of the geotextile layers on load-bearing capability. However, despite this impressive strength profile, geotextiles often exhibit certain drawbacks. One such drawback is their tendency to have lower water flow rates. This limitation can be a significant concern in applications where efficient drainage or water permeability is essential. When the flow rate of water through the geotextile is markedly slow, it fosters the development of an unstable soil filter cake, potentially leading to the erosion of fine soil particles and consequently compromising the overall soil stability. Moreover, conventional geotextiles tend to feature higher Apparent Opening Size (AOS), thereby allowing relatively larger particles to pass through. However, this also implies a disadvantage that this geotextile is not effective in retaining finer soil particles or preventing erosion or soil stabilization. Furthermore, geotextiles typically exhibit a nominal coefficient of friction with soil. While this may suffice for some applications, it may not provide the optimal level of stability required for stabilizing soft soil and retaining small soil particles. Therefore, there is a long-felt need for developing geotextiles that offer a balanced combination of properties such as coefficient of friction, AOS, and flow rate of water to meet the requirements for stabilizing soft soil effectively, thus providing geotextiles with these desired characteristics.
