Filament geotextile is a polyester filament needle punched non-woven geotextile that does not contain chemical additives or undergo heat treatment. It is an environmentally friendly building material.
1. Strength - Under the same weight specification, the tensile strength in all directions is higher than that of other needle punched non-woven fabrics;
2. UV resistance - with extremely high UV resistance;
3. Extremely high temperature resistance - up to 230 ºC, maintaining structural integrity and original physical properties at high temperatures;
4. Permeability and planar drainage - Geotextiles are thick and needle punched, with good planar drainage and vertical permeability, and can still maintain this performance after many years;
5. Creep resistance - Geotextiles have better creep resistance than other geotextiles, therefore they have good long-term performance. It can withstand the erosion of common chemical substances in soil and the corrosion of gasoline, diesel, etc;
6. Ductility - Geotextiles have good elongation under certain stress, allowing them to adapt to uneven and irregular base surfaces;
