Non-woven geotextile mainly by the synthetic fiber through acupuncture or woven into the water-permeable geosynthetics. Now the use of a very wide range, then we will talk about how to produce non-woven geotextile and the main purpose.

How to produce?

Non-woven geotextiles can be used to reinforce soil materials to reinforce soft ground or build lightweight retaining walls, while also reducing pore water pressure under embankments. Drainage system for earth dam, underground drainage pipes, weak foundation reinforcement, a variety of embankment slope pads and other engineering filter layer. Has been widely used to solve the roadbed subsidence and mud mud problem.

The development of non-woven geotextiles fast, and has become a major part of geotextiles. Non-woven geotextile with greater elongation, to adapt to greater deformation, can be made into the appropriate size of the pores, and in the horizontal and vertical directions have better penetration. The raw materials used to polyester, followed by polypropylene and vinylon, the unit weight of 100 to 800 grams / square meter. The emergence of non-woven geotextiles later than weaving, the production methods are mainly spunbond method and acupuncture two, including acupuncture in our country a larger proportion.

The main purpose:
   1. Man-made earthwork ground drainage base.
   2. Exclude water seepage around the tunnel to reduce the lining of the external water pressure and seepage around the building.
   3. Dams or embankments in the impermeable geomembrane behind or the concrete surface of the lower drainage.
   4. Vertical or horizontal drainage within the earth dam, buried in the soil to dissipate pore water pressure.
   5. Roads, airports, railways and artificial rock and other rockfill with the foundation between the geotextile isolation layer.
   6. hydraulic engineering wells, relief wells or baroclinic filter layer.
   7. Drainage around the drainage pipe or gravel drainage ditch around the filter.
   8. The storage layer of the upper dam surface of the storage dam or tailings dam and the filter layer of the drainage system in the retaining wall backfill.
   9. artificial filling, rockfill or material field and foundation isolation layer, isolation between different layers of frozen soil. From the filter and reinforcement.
   10. Road ballast and subgrade isolation layer, or between the subgrade and soft ground isolation layer.
   11. Increase the stability of gravel slope and reinforced soil to prevent water loss and soil erosion and soil damage at low temperature.
   12. Strengthen flexible pavement, repair the cracks on the road to prevent the reflection of cracks in the road.
   13. For retaining wall backfill in the reinforcement, or for retaining the retaining wall panels. Build a wraparound retaining wall or abutment.
   14. River, river, lake, bank of the sea geotextile fabric, but also to prevent running water turbidity. Roads (including temporary roads) Railways, embankments, earth-rock dams, airports, sports fields and other projects, to strengthen the soft ground, at the same time from the role of isolation and filtration.
