Pp Nonwoven Needle Punch Geotextiles

Product Details:

We can manufacture PP Nonwoven Needle punched Geo Textiles on PP Staple Fiber Needle punched Technology.

Needle-punched non-woven Geotextiles are made from polypropylene fibers that are tangled together by a needle-punching process. The fibers may be made in continuous or short lengths (the short length fibers are called staple fibers) and 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. They are also commonly used with geomembranes to provide a protective cushion.

• PP Non Woven Geotextiles are designed in such a way to perform the following 4 criteria
• Retention, Permeability, Clogging and Survivability
• Retention : This is a very important criteria. It prevents excessive migration of soil
• Permeability : Permeable enough so that liquids are allowed to flow without disturbing the flow rate
• Clogging : Enough pore openings to help filteration even if a few pores are clogged
• Survivability: Must show strength, chemical resistance, environmental resistance and maintain sustainability throughout the usage life

• Separation function: Separation of two layers of soil with different soil physical properties, such as road gravel from soft sub-base materials
• Filteration function: Retaining fine particles when water passes from a fine-grained to a coarse grained layer, such as when water flows from a sandy soil into a Geotextile wrapped gravel drain
• Drainage function: To drain liquid or gas in the plane of the fabric which results in draining or venting of the soil, such as a gas vent layer in a landfill cap
• Reinforcement function: Improving the load bearing capacity of a soil structure, such as a high strength Geotextiles to reinforce a retaining wall
• Protection function: Mechanical protection of geomembranes against perforation and abrasion, such as a liner protective layer when only gravel fills are available
