Long Filament Spunbond Needle Punched Non-woven Geotextile
Material：polyester
Feature：mechanics, longitudinal and transverse drainage, extensibility, permeability, filtration, acid and alkali resistance, aging resistance
Application Field：roads, railways, dikes, coastal mudflat, coastal marshes, landfill sites
Shipping Method：logistics
Product Category：Geotextile Fabric
Spunbond needle-punched nonwoven geotextile is produced by polyester filament web formation and consolidation methods, with fibers arranged in a three-dimensional structure.
Performance
In addition to excellent mechanical properties, Long Filament Spunbond Needle Punched Non-woven Geotextile also possesses good longitudinal and transverse drainage, extensibility, permeability, filtration, as well as high chemical resistance to acids, alkalis, and aging.
Application
It is primarily used for reinforcement, filtration, separation, and drainage in projects such as highways, railways, embankments, and coastal tidal flats, and is particularly suitable for coastal marshes and landfill sites.
