Wandafu Long Filament Polyester Corrosion Resistant Spunbond Needled Geotextile Dam Slope Protection Landfill Filtration Highway Subgrade
Long Filament Spunbond Needled Geotextile
Long filament spunbond needle-punched nonwoven geotextile is manufactured by forming polyester filaments into a web and consolidating them through a needle-punching process. Its fibers feature a three-dimensional interlocking structure, which not only endows the product with excellent mechanical strength but also delivers outstanding longitudinal and transverse drainage performance, elongation capacity, water permeability, and filtration efficiency. Additionally, it boasts superior chemical properties such as high acid resistance, aging resistance, and durability in harsh environments.
Product Features
High Mechanical Strength: The three-dimensional fiber structure enhances tensile, tear, and puncture resistance, ensuring stable performance in engineering applications.
Excellent Creep Resistance: Maintains shape and load-bearing capacity over long-term use, avoiding deformation under persistent stress and ensuring project durability.
Superior Corrosion & Aging Resistance: Resistant to acids, alkalis, chemicals, and ultraviolet (UV) radiation, with good heat resistance. Suitable for both indoor and outdoor harsh environments, extending service life.
Outstanding Hydraulic Performance: Optimized pore structure enables efficient filtration, drainage, and water permeability, effectively preventing soil particle loss while ensuring smooth water flow.
Stable Dimensional Stability: Low shrinkage rate under temperature changes and mechanical stress, ensuring consistent performance throughout the project cycle.
Easy Construction: Lightweight, flexible, and easy to cut and lay, adapting to complex terrain and reducing construction time and labor costs.
Product Applications
It is widely used in various civil engineering and environmental protection projects, mainly for the following scenarios:
Anti-seepage, reinforcement, and slope protection in dams, embankments, and dikes
Water interception, filtration, and drainage in highway, railway subgrades, and airport runways
Asphalt pavement renovation and maintenance (preventing reflective cracks, enhancing pavement stability)
Soil consolidation and erosion control in ecological restoration, river regulation, and coastal protection projects
Filtration and separation in landfills, sewage treatment plants, and water conservancy projects
Green roof, garden landscape, and agricultural irrigation system filtration and drainage
