Product Description
Short Nonwoven Geotextile
Product Introduction：
Staple geotextile i non-woven fabric machinery with polyester staple fiber as the main raw material,by opening, carding, laying nets,nedlingand other processes produced.
Performance Characteristics:
*High strength, due to the use of plastic fibers, can maintain suficient strength and elongation in wet and dry conditions.
*Corrosion resistance, long-term corrosion resistance in soil and water with different pHlevels.
*Good water permeability, there is a gap between the fibers, so it has good water seepage performance.
*Good resistance to microorganisms, insects are not damaged.
*Convenient construction, because the material is light and soft, it is convenient for transportation, laying and construction.
*Light weight, low cost, corrosion resistance,with reverse filtration, drainage, isolation, enhancement and other benign properties.
