Introduction
Staple fibers needle punched non woven geotextile is made of PP or PET staple fibers on
carding cross-laying equipment and needle punched equipment.
Polyester filament geotextile is made of polyester filament yarn, which is processed by
netting equipment and needle punching equipment.
Features:
Staple fibers needle punched non woven geotextile owns the advantages of acid and alkali
resistance, erosion resistance, aging
resistance, large strength, stable size, good filtrability etc.
Polyester filament geotextile has the advantages of high strength, strong puncture
resistance, anti-microbial, aging resistance, high temperature resistance, excellent
water permeability, filterability, soil retention and so on.
Application:
The main function is to strengthen, isolate, filter, drain, It is widely used in water conservancy, highway, railway, landfill and other fields.
