Production introduction:
PP Continuous Filament Nonwoven Geotextile is mechanically bonded continuous filament nonwovens from 100% UV stabilized polypropylene. It can offer excellent water flow properties for drainage and other applications

PP Staple Fiber Nonwoven Geotextile is composed of polypropylene fibers which are formed into a stable network such that the fibers retain their relative position,It is inert to biological degradation and resists naturally encountered chemicals, acids and alkalis.

Functions:
− Separation
Paved and unpaved roadway applications are stabilized when the geotextile is placed at the subgrade/aggregate interface.
− Filtration
Nonwoven geotextiles provide superior hydraulics property and soil retention, making them ideal for filtration in subsurface drainage systems
− Cushioning
The nonwoven geotextile lessens the impact to the road structure when placing at the subgrade/aggregate interface.
