Short Nonwoven Geotextile
Product Introduction
Short filament nonwoven geotextile is manufactured using nonwoven machinery, with polyester staple fiber as the primary raw material. It is produced through a series of processes including fiber opening, carding, web laying, and needle punching.
Performance Characteristics
High Strength: Made from synthetic fibers, it maintains excellent strength and elongation in both wet and dry conditions.
Corrosion Resistance: Offers long-term durability in soils and water with varying pH levels.
Permeability: The voids between fibers provide effective water permeability and seepage performance.
Microbial Resistance: Resistant to microorganisms and insect damage.
Easy Installation: Lightweight and flexible, facilitating easy transport, laying, and construction.
Lightweight & Cost-Effective: Combines low weight and cost with strong resistance to corrosion, along with functions such as filtration, drainage, isolation, and reinforcement.
