Polypropylene Needle Punch,Multifilament Geotextile

Geotextile For Agriculture function to prevent mutual mixing between two layers of soil having different particle sizes or different properties. Filtration involves the establishment of a stable interface between the drain and the surrounding soil. In all soils water flow will induce the movement of fine particles. Initially a portion of this fraction will be halted at the filter interface; some will be halted within the filter itself while the rest will pass into the drain. The Geotextile provides an ideal interface for the creation of a reverse filter in the soil adjacent to the Geotextile. The complex needle-punched structure of the Geotextile provides for the retention of fine particles without reducing the permeability requirement of the drain.
