Geotextiles are synthetic materials designed to improve the performance and longevity of civil engineering projects by providing reinforcement, separation, filtration, and drainage functions. There are several types of geotextiles, each engineered to address specific challenges in construction and environmental applications. Here are some common types:

Types of geotextiles fabric based on weaving methods

1, Woven Geotextiles fabric

Woven geotextile fabric, also known as woven geotextile, is a geosynthetic material characterized by a combination of strong tensile properties and a relatively thin thickness. Typically available in thicknesses of 0.2mm, 0.4mm, and 0.7mm, this fabric boasts robust tensile strength, approximately 250kg/cm², and a significant permeability coefficient of about 6.1*10^-4cm/s.

Constructed through the interweaving of warp and weft yarns, woven geotextile fabric is composed of parallel yarns forming the warp and weft directions. The warp represents the set of yarns aligned with the longitudinal axis of the weaving machine, while the weft comprises the yarns arranged perpendicular to the machine's direction.

Adaptable to various applications, woven geotextile fabric can be woven to different thicknesses and compaction levels. Generally, it consists of cotton yarns arranged in at least two parallel sets. The fabric exhibits exceptional compressive strength, particularly in the warp direction, providing reliable performance.

Woven geotextile fabric can be categorized into reinforced and unreinforced types, based on variations in manual weaving processes and the application of additional strengthening elements. Reinforced woven geotextile fabric, in particular, demonstrates significantly higher compressive strength in the warp direction compared to conventional geotextiles.

Primarily utilized in geotechnical construction projects, woven geotextile fabric finds application in reinforcement and enhancement of soil structures. Its thin yet resilient nature, coupled with superior compressive strength, makes it an ideal choice for projects where reliable performance and reinforcement are critical.

2,Non-woven geotextiles fabric

Non-woven geotextile fabric is produced by arranging polyester filaments or short fibers into a honeycomb structure through different machinery and processing techniques. Following processes such as needle punching, the various chemical fibers are intertwined and interlocked, solidifying the fabric and ensuring standardization. This treatment imparts qualities of softness, fullness, strength, and rigidity to the fabric, exceeding various thickness considerations for specific applications.

Non-woven geotextile fabric exhibits excellent textile porosity, providing superior adhesion and cohesion due to the interlacing of chemical fibers. The softness of the chemical fibers ensures essential tear resistance, and the fabric demonstrates excellent deformation adaptability and drainage capabilities. The surface's softness and multiple voids contribute to effective frictional resistance, enhancing the adhesion of coarse particles and preventing the unnecessary flow of fine particles. This feature helps avoid the removal of unnecessary moisture.

The surface's softness also contributes to excellent maintenance capabilities. Non-woven geotextile fabric can be categorized based on the length of the filaments, such as polyester filament non-woven geotextile fabric or short-fiber non-woven geotextile fabric. Both types offer outstanding filtration, protection, reinforcement, and safety functions, making them widely used as geosynthetic materials in various engineering applications.

1), Strength and Load Distribution:

Woven geotextiles have a significant advantage in terms of tensile strength and load distribution, making them preferable for projects where these characteristics are critical.

2), Filtration and Drainage:

Non-woven geotextiles outperform woven types in terms of filtration and drainage capabilities. They are more suitable for applications where water permeability and filtration efficiency are paramount.

3), Versatility:

Both woven and non-woven geotextiles have versatile applications. The choice between the two depends on specific project requirements and priorities.

In conclusion, the selection of geotextiles depends on the specific needs of a project. Woven geotextiles offer strength and stability, while non-woven geotextiles excel in filtration and drainage. Engineers and construction professionals must carefully consider these factors to ensure the optimal performance of geotextile materials in their projects.
