Non woven geotextile is formed by long yarn or short fiber laid to net sharp by different equipments and technology, different fibers interwining with each other through needle punching etc technics, this would make the fabrics normalized, soft, plump, thick and stiff to meet different thickness and usage requirements.



Non woven geotextile has good fabric gap and adhesion, meanwhile it has excellent adaptive ability to deformation and plane drainage capacity because of the fiber is soft and has a certain degree of anti-breaking ability. Non woven geotextile has good friction coefficient because of the soft surface and gaps, which could increase the adhesion capability of soil particles etc and prevent the loss of particles at the same time rule out the excess water.So soft surface has perfect protection ability. According to the yarns length, it could be divided into long yarn and short yarn non woven geotextile, both of them have great filtering, isolation, reinforcement, protection etc effects, which is a kind of widely used geosynthetics.


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.
