Polyester filament geotextiles are polyester filament needle-punched non-woven geotextiles that no chemical additives and no heat treatment, it is an environmentally friendly construction materials.

Characteristics

1.Strength: higher tensile strength in all directions than other needle-punched non-woven fabrics under the same grammage specification.

2.UV light resistance: high UV resistance.

3.High temperature resistance: high temperature resistance up to 230°C, retaining structural integrity and original physical properties at high temperatures.

4.Permeability and planar drainage: filament geotextiles are thicker and needle-punched, providing good planar drainage and vertical permeability, which is maintained after many years.

5.Creep resistance: filament geotextiles are more resistant to creep than other geotextiles and therefore have good longevity. It is resistant to erosion by common chemicals in the soil and to corrosion by petrol, diesel, etc.

6.Ductility: filament geotextiles have good elongation under certain stresses, enabling them to adapt to uneven and irregular substrates.
