A geotextile is typically defined as any permeable textile material used to increase soil stability, provide erosion control or aid in drainage. Geotextiles can be categoried as non woven geotextile and woven geotextiles. Non woven geotextiles are usually made from a synthetic polymer such as polypropylene, polyester, polyethylene and polyamides. Varying polymers and manufacturing processes result in an array of geotextiles suitable for a variety of civil construction applications.
Non-woven geotextiles resemble felt and provide planar water flow. They are commonly known as filter fabrics, although woven monofilament geotextiles can also be referred to as filter fabrics. Typical applications for non-woven geotextiles include aggregate drains, asphalt pavement overlays and erosion control. Nonwoven fabrics can be made of either polyester or polypropylene . Nonwoven filter fabrics are used as separation fabrics when higher water flow is required for the application. This can include acting as a separator between the drainage gravel backfill behind a retaining wall, wrapping the stone surrounding the pipe in a french drain, or as an underlayment below riprap. Nonwoven fabrics can also be treated to resist water flow and used as a pavement underlay by binding with the asphalt to create a barrier to water.

Nonwoven Geotextiles are placed between different soil layers or between soil and other materials (such as aggregate or geomembranes) to prevent mixing and maintain the integrity of the layers. This helps prevent the loss of structural integrity due to intermixing of materials and reduces the risk of settlement.
1.2 Filtration
Nonwoven Geotextiles act as filters to allow the passage of water while retaining soil particles. They are used to prevent the clogging of drainage systems, such as French drains or geocomposite drains, by filtering out fine particles and preventing soil migration.
1.3 Drainage
Nonwoven Geotextiles with high permeability allow water to pass through while preventing the movement of soil particles. They are used in drainage applications to facilitate the flow of water away from structures, roads, or other areas susceptible to water accumulation.
1.4 Reinforcement
Nonwoven Geotextiles can be used to reinforce soil structures, such as retaining walls, embankments, and slopes, by distributing loads and reducing the risk of soil erosion and failure. They improve the stability and strength of soil structures, particularly in areas with poor soil conditions or high traffic loads.
1.5 Erosion Control
Nonwoven Geotextiles help stabilize soil surfaces and prevent erosion by protecting against surface runoff, wave action, and wind erosion. They are used in applications such as slope stabilization, shoreline protection, and revegetation projects to mitigate the effects of erosion and maintain soil stability.

3. What Are Categories of Non Woven Geotextile?
Non woven geotextile can be categorized based on various factors, including manufacturing process, material composition, application, and performance characteristics. Here are some common categories of nonwoven geotextiles:
3.1 Needle Punched Nonwoven Geotextiles
These geotextiles are manufactured using a needle-punching process, where synthetic fibers are mechanically entangled and interlocked to form a cohesive fabric structure. Needle-punched geotextiles are known for their high strength, durability, and puncture resistance, making them suitable for applications requiring robust performance, such as separation, filtration, and reinforcement.This is the most common use geotextile.
3.2 Thermal Bonded Nonwoven Geotextiles
Thermal-bonded geotextiles are produced by heating and melting synthetic fibers to bond them together, forming a stable fabric structure without the use of adhesives or mechanical entanglement. Thermal-bonded geotextiles exhibit uniformity, smoothness, and excellent filtration properties, making them ideal for applications such as drainage, erosion control, and protection of geomembranes.
3.3 Spunbonded Nonwoven Geotextiles
Spunbonded geotextiles are manufactured using a continuous extrusion process, where synthetic fibers are spun and laid down onto a conveyor belt to form a web. The web is then bonded together using heat and pressure to create a strong and durable fabric. Spunbonded geotextiles offer high tensile strength, flexibility, and resistance to UV degradation, making them suitable for various civil engineering and construction applications, including reinforcement, separation, and filtration.
3.4 Meltblown Nonwoven Geotextiles
Meltblown geotextiles are produced by extruding molten polymer through fine nozzles to create microfibers, which are then randomly deposited onto a conveyor belt to form a porous web. The web is then bonded together using heat or pressure to create a cohesive fabric structure. Meltblown geotextiles exhibit excellent filtration properties, making them ideal for applications such as drainage, erosion control, and filtration of fine particles.
3.5 Composite Nonwoven Geotextiles
Composite geotextiles consist of multiple layers of different nonwoven geotextile fabrics or other geosynthetic materials bonded together to form a single integrated product. Composite geotextiles combine the beneficial properties of different materials to achieve specific performance requirements, such as enhanced filtration, drainage, or reinforcement.
3.6 Biodegradable Nonwoven Geotextiles
