Filament Polyester Geotextile Long Fiber Geofabric

Filament Polyester Geotextile Long Fiber Geofabric

Polyester filament geotextiles and short-fiber geotextiles are both commonly used geosynthetic materials, but they have obvious differences in raw materials, production processes, performance characteristics and application scenarios. The following are the specific differences:

The raw material of filament polyester geotextile is polyester chips, which are made of high-purity and high-molecular-weight polyester polymers. The raw materials of short-fiber geotextiles are also polyester chips, but other fibers such as polypropylene may also be mixed in.

Polyester filament geotextiles are made into continuous filaments through melt spinning. The filaments are carded into a web and then needled and reinforced (or thermally bonded) to form fabrics. The fibers are closely combined with each other, and there are no short fiber breaks. Short-fiber geotextiles are first made by melt spinning polyester chips into short fibers. After the short fibers are loosened and carded into a web, they are consolidated into fabric through needling or chemical bonding processes. The fiber ends are exposed and the surface is relatively rough.

Long-fiber geofabric has high strength, stable water permeability, good corrosion resistance and wear resistance, and strong durability. Short-fiber geotextiles have low strength, fluctuating water permeability and poor wear resistance, but they are low in cost and easy to construct.

Polyester Geotextile fabric advantages:

◆High Tensile Strength: Filament polyester geotextiles are known for their high tensile strength, which makes them suitable for applications requiring reinforcement and stabilization, such as road construction and embankment reinforcement.

◆Durability: These geotextiles are highly durable and resistant to UV degradation, chemicals, and biological degradation, ensuring long-term performance even in harsh environmental conditions.

◆Excellent Filtration Properties: They provide effective filtration by allowing water to pass through while retaining soil particles, which helps in preventing soil erosion and maintaining the integrity of the structure.

◆Good Drainage: The structure of filament polyester geotextiles facilitates efficient drainage, reducing the risk of water accumulation and associated problems like soil saturation and structural instability.

◆Resistance to Creep: Polyester has a low creep potential, meaning it maintains its shape and strength under constant stress over time, which is crucial for long-term stability in reinforcement applications.

◆Flexibility: These geotextiles are flexible and can conform to the shape of the underlying surface, providing uniform support and stress distribution.

◆Ease of Installation: Filament polyester geotextiles are relatively easy to handle and install, which can reduce labor costs and installation time.

◆Cost-Effective: Given their durability and long service life, filament polyester geotextiles can be a cost-effective solution for many engineering projects, reducing the need for frequent replacements or repairs.

◆Environmental Benefits: By preventing soil erosion and promoting vegetation growth, these geotextiles can contribute to environmental conservation efforts.
