Staple Geotextile Lightweight and Durable Non-Woven Material for
Various Applications
Product Introduction
Staple fiber geotextile is a kind of non-woven geotextile material
made by non-woven production equipment with staple fiber as raw
material. It has a variety of excellent characteristics, especially
excellent performance in corrosion resistance, suitable for a
variety of engineering environments.
Product Properties
1. Corrosion resistance: staple fiber geotextile with polypropylene
or polyester and other chemical fiber as raw materials, with acid
and alkali resistance, no corrosion, no moth, anti-oxidation
characteristics.
2. Water permeability: Maintain high water permeability, even under
the pressure of soil and water can maintain good water
permeability.
3. Strength and durability: The use of plastic fibers can maintain
full strength and elongation in both dry and wet conditions.
4. Antimicrobial: Good resistance to microorganisms and insects.
Product Application
1. Water conservancy projects: DAMS, reservoirs and other projects,
used for isolation and reinforcement.
2. Road construction: reinforcement of railway roadbed, maintenance
of highway pavement.
3. Environmental protection projects: landfills, sewage treatment
plants, etc., to prevent the spread of pollutants.
4. Coastal beach: used for reclamation, moisture-proof and other
projects.
