1.Brief Introduction to Needle Punched Geotextile Fabric
1.1 Definition of Needle Punched Geotextile Fabric
Needle Punched Geotextile Fabric is often made from polypropylene or polyester fibers processed by woven, needle-punched or heat-bonded methods. Short fiber needle punched geotextile fabric is made from 100% virgin staple polypropylene fibers that are tangled and interlocked with each other by needle-punching process. It is the kind of non woven geotextile fabric which is robust, durable, permeable and resist to deformation.

There are different types of Needle Punched Geotextile Fabric available in China, each designed for specific applications. Here are some common types and their brief applications.
1.2.1 Staple Fiber Needle Punched Geotextile Fabric
BPM Staple Fiber Needle Punched Geotextile is produced from polyester or polypropylene Fiber by different equipment and technology to get different thickness.The main function is filtration, drainage, reinforcement. lt has good impermeability and resistance to deformation.
BPM Staple Fiber Needle Punched Geotextile are widely used in various applications, including:
- Reinforcement in retaining wall backfill.
- Strengthen the wek road and fix the cracks on the road.
- Improve the stability of slope and reinforcement soil, avoid water and soil loss and soil frozen injure.
- Isolation layer of artificial backfill soil stone with foundation and different tundra.
- Filtration layer of drainage pipe or gravel sub-drain. F. Vertical or horizontal drainage; Bury in soil to release air pressure.
- Reinforce the weak foundation of engineering of road, railway, embankment, airport.

1.2.2 Filament Needled Punched Geotextile Fabric
Filament Needled Punched Geotextile Fabric is made from virgin continuous polyester filament by needle punching and thermally bonding process to form strong fabric that retains its dimensional stability and is resistant to damage from construction stresses.Polyester filament non woven geotextile is widely used for separation, filtration, drainage, protection and reinforcement functions in civil environmental engineering and construction projects.
Separation. To separate building materials with different physical properties such as soil and sand, sand and gravel, soil and concrete, etc. Keep the two or more materials from losing or mixing, and maintain the overall structure and function of the material, such as the effective isolation between the roadbed and the foundation, the foundation and the embankment, the geomembrane and the sand draining layer.
Soft foundation reinforcement. To enhance the tensile strength and anti deformation ability of soil can enhance the stability of building structures such as trash impurities, base soil or stone layer, airport railway, playground, runway, landfill and so on, so as to improve the quality of soil.
Filter. When the water flows into the coarse soil layer from the fine soil layer, the geotextile can make the water flow through the good permeability and permeability of geotextiles, and effectively interception the soil particles, fine sand and small stones, so as to keep the stability of the soil and water engineering.
Drainage. installed in the geomembrane, the playground or the railway track bed.
Protection. effectively diffuse, transfer or decompose the stress of civil engineering so as to prevent soil from being damaged by external force.
