Short Fiber Needle-punched non-woven Geotextiles are made from PET/PP fibres that are tangled together by a needle-punching process. The fibres that achieve their strength by interlocking. Needle-punched non-woven Geotextiles have excellent water flow rates and are used for filtration of soil fines for drainage applications including trench drains, as a wrapping for perforated pipe, for erosion protection, and combined with three-dimensional structures to create prefabricated drains.
Color: White or custom-made
Temperature Range: -60°C ~ +170°C
Permeability: Excellent uniformity with high permeability and low pore size for soil filtration.
Storage and transportation is convenient: Because of light weight, packing can be according to certain requirements, so the transport, storage, construction is very convenient.
While the non woven fabric can be used in almost any stabilization,separation or cushioning application, they are most commonly used in areas that also require filtration. The non woven design of the material provides a higher rate of flow through,making it easier for water to pass through the material.Some common uses of the material includes the following:
