The needle-punched non woven geotextile is produced from polyester or polypropylene fiber by different equipment and technology to get different thickness .The main function is filtration ,drainage ,reinforcement .It has good impermeability and resistance to deformation.
Filament polyester geotextile
The filament non-woven geotextile is produced from polyester long fiber forming into net and consolidation with three dimension structure.It's kind of new material in geotechnical and engineering project .Except for its good mechanical properties of tensile strength and puncture resistance ,it also has good drainage ability ,acid and alkali resistance and anti-aging .The wider opening size allows it has good permeability and filtration .

>> Function of geotextiles
1.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. 2.Reinforcement 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 earthbody stability. 3.Protection It prevents the bank from being washed out, protects the bank and the
bottom, prevents the water and soil from being washed away
>>Application
All have a wide range of applications and are currently used to advantage in many civil engineering applications including roads,airfields,railroads,embankments,retaining structures,reservoirs,canals,dams,bank protection coastal engineeringand reinforce the roadbed.
