Filament needle punched non-woven geotextile:

1.  Engineering applications of continuous filament needle-punched geo-textile: can filtrating two sides in water conservancy project and slope protection project; separation; reinforcement and drainage in projects of earth slope and retaining wall. Handle the soft ground in port project, reinforcement and drainage function in projects of beach diking, ocean port, slope and dike.

2.  Technical characteristics of continuous filament needle-punched geo-textile: a kind of geo-synthetics used in geo-technical engineering and civil engineering, which is made of PP/PET continuous filament by paving the filament net and concretion method, thus produced the fabric. Its fiber is arrayed a three dimensional structure and devious hole distributing. Besides its fine mechanical characteristics, it has chemical stability like fine drainage, capacity in both directions, good capacity of elongation and high biology tolerance, alkali tolerance, acidity tolerance, weather resistance, good permeability and filtration, etc.
