Filament woven geotextile has good mechanical function, good water permeability, corrosion resistance, aging resistance, isolation, anti filtration, drainage, protection, stability, reinforcement and other functions, can adapt to uneven base course, can resist external force damage during construction, creep is small, and can still maintain its original function under long-term load. Under the same weight specification, the tensile strength in all directions is higher than that of other needle punched non-woven fabrics; Anti UV light has high resistance to UV radiation Filament woven fabric, also known as polyester filament spunbonded needle punched nonwoven geotextile, polyester filament geotextile, polyester filament non-woven geotextile, permeable geotextile, etc., is made of new PET polyester chips, which are spun, mesh laid, and needle punched for reinforcement. The general width is 4-6 meters and the length is 50-100 meters. Polyester filament spunbonded needle punched nonwoven geotextile is made from brand new polyester chips as raw materials, which are spun, mesh laid, and needle punched for reinforcement Filament woven fabrics have high temperature resistance, with a high temperature resistance of up to 230 ℃. They still maintain their structural integrity and original physical properties at high temperatures; Permeability and planar drainage, geotextile is thick and needle punched, with good planar drainage and vertical permeability, and can still maintain this performance after many years; 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 Filament woven fabrics have good elongation under certain stress, allowing them to adapt to uneven and irregular substrates; The geotextile is thicker, which can ensure the three-dimensional void ratio of geotextile, and is conducive to the realization of excellent hydraulics performance. The breaking strength of geotextile has great advantages, especially suitable for reinforcement of retaining walls and embankments. The indicators of geotextile exceed the specified standards and are excellent geotextile reinforcement materials
