Product Description
100% Polyester Continus Long Fiber Needle Punched Nonwoven Geotextile Fabric for Sand Filtration, Pavement Reinforcement
Geotextiles are permeable geosynthetic materials made by needle-punched or woven synthetic
fibers. The raw materials are PET or PP. Geotextiles comprise woven geotextiles and non-woven filament/stable fiber geotextiles.
Main Features:
1)anti-aging, the product has very high anti-ultraviolet radiation ability, not easy to degradation.
2) High temperature resistance to up to 230ºC maintaining structure stability and original physical properties.
3) High flat drainage and vertical permeability.
4) High creep resistance.
5) Resistance of erosion of chemicals in soil with the corrosion of gasoline and diesel etc.
6) High elongation under certain stress, thus able to adapt to uneven and irregular bases.
Good ductility
Strong elasticity and deformation ability. Not easy to break and deform
Anti-seepage and puncture-resistant
Prevents plant roots from passing through. Good anti-seepage effect
Wear-resistant and corrosion-resistant
Good chemical stability, high elongation, high tensile strength

Geotextile Production Process
APPLICATION
Major functions: Separation, filtration, drainage, reinforcement, protection, and liquid barrier
1) Filtration The filtration layer of the dykes, river canal, seacoast, concrete slope, retaining walls. At the same time of preventing the clay granule from passing, it allows the water and the gas pass through freely.
2) Separation The isolation of the railway dregs and the roadbed, roadbed and the soft base, surface of the airdrome and parking lot and the groundsill, different dam materials. It isolates the soil and the gravel of two kinds different granule pathway from the groundsill or other buildings.
3)Adding muscle The highway, railway, soil-stone dam, breakwater, airport, backfill soil of retaining wall, slope protection, etc in which distributes the earth stress, prevents the side-displacement of the earth body and improves the earth body stability.
4)Protection It prevents the bank from being washed out, protects the bank and the bottom, prevents the water and soil from being washed away.
