Nonwoven Filtration Fabric PET Filament Polyester Nonwoven Geotextile Anti-Aging Industrial
Long filament spunbond nonwoven geotextile" refers to a geotechnical material used in civil and soil engineering. Let's break down the components of this name:
1, Long Filament: This indicates that the fibers used in the geotextile are made from long filaments rather than short fibers. Long filaments typically provide higher strength and stability.
2, Spunbond: This signifies that the fibers are manufactured using a spunbond process. In this process, polymer particles are melted and formed into fibers through a spinning nozzle. These fibers are then randomly arranged and bonded together.
3, Nonwoven: This indicates that the geotextile is produced by directly forming fibers rather than through traditional weaving processes. Nonwoven geotextiles are known for their high strength, permeability, and filtration properties.
4, Geotextile: This specifies that the material is designed for use in geotechnical and soil engineering applications.
Geotextiles are commonly used to enhance soil performance, control erosion, provide separation layers, and improve drainage systems. In summary, a "Long filament spunbond nonwoven geotextile" is a high-performance material for civil and soil engineering. It combines the characteristics of long filaments, spunbond processing, and nonwoven construction, offering various applications such as erosion control, road construction, landfill engineering, subsurface drainage systems, and railway infrastructure.

Application scenarios of polyester filament geotextile
Polyester filament geotextile is widely used in many engineering fields due to its advantages such as high strength, corrosion resistance, water permeability and thermal stability. The following is a comprehensive analysis of its core application scenarios:
Water conservancy projects
Dyke filtration and anti-seepage
The anti-filtration layer used for dam slope protection prevents soil erosion and foundation settlement. At the same time, it is used in combination with geomembranes to form an anti-seepage structure to reduce the risk of leakage.
Channel and reservoir projects
Isolate different soil materials to protect the stability of the channel structure; as a drainage layer in reservoir construction, it reduces pore water pressure and enhances the anti-seepage of the dam body.
Transportation infrastructure
Highway and railway subgrade reinforcement
Layed in the subgrade to isolate soft soil and gravel layers, delay reflective cracks, and improve the bearing capacity of the foundation.
Airport runway and port engineering
Used for runway foundation drainage to prevent frost heave; used as a reinforcement layer in the soft foundation treatment of ports to enhance the stability of beach dikes.
Environmental protection and waste disposal
Landfill anti-seepage system
As part of the anti-seepage composite layer, it is used in combination with geomembranes to isolate pollutants and prevent leachate leakage.
Isolation of polluted soil and ecological restoration
It is used as an isolation barrier for polluted sites to prevent the spread of harmful substances; it fixes soil in ecological restoration and promotes vegetation recovery.
