Performance Characteristics

1, High tensile strength and initial modulus, with small elongation at break and creep.

2, Stable structure maintained by the mutual extrusion of warp and weft yarns, making high-strength woven geotextile particularly suitable for reinforcement, strengthening, and isolation purposes.

Design and Construction Considerations

1, High-strength woven geotextile functions as a planar filter with large pore sizes, ranging from 0.05 to 0.08 mm. During anti-filtering, small sand and gravel particles are prone to wash away.

2, Flat yarn woven geotextile is susceptible to clogging. Single yarn fabrics are less prone to clogging and are suitable as non-cohesive soil filter layers.

3, The fabric has a small thickness, limited horizontal drainage capability, and is not suitable as a drainage material. Woven fabric has low elastic elongation and is prone to puncture and penetration when in contact with hard materials.

4, Polypropylene woven fabric exhibits strong resistance to acid and alkali, while polyester woven fabric has strong resistance to ultraviolet radiation.

5, It can be made into fabric bags filled with concrete for shore protection projects.

Please note that technical terms may vary, and it is advisable to consult industry-specific terminology and standards for precise translations in certain contexts.

Applicaitons

1, Road Construction and Pavement Reinforcement:

Filament woven geofabrics are often used in road construction to enhance the stability and performance of pavements. They help distribute loads and reduce the potential for reflective cracking in asphalt overlays.

2, Soil Reinforcement and Stabilization:

Geofabrics are used to reinforce and stabilize soil in applications such as embankments, slopes, and retaining walls. They improve the overall strength of the soil and prevent erosion.

3, Railway Track Stabilization:

Filament woven geofabrics are employed in railway construction to stabilize the underlying soil and provide additional support to the track structure. They help reduce settlement and increase the load-bearing capacity of the track bed.

4, Erosion Control:

Geofabrics are used for erosion control in riverbanks, shorelines, and other areas prone to soil erosion. They prevent the loss of soil particles while allowing water to pass through, promoting vegetation growth.

5, Retaining Walls and Reinforced Earth Structures:

Filament woven geofabrics play a crucial role in the construction of reinforced earth structures and retaining walls. They provide tensile strength to the structure and enhance its stability.

6, Tunnel Construction:

Geofabrics are employed in tunnel construction to provide support and reinforcement to the surrounding soil or rock.

7, Coastal and Shoreline Protection:

Woven geofabrics contribute to coastal and shoreline protection projects by preventing soil erosion and stabilizing the shoreline.

Construction Attentions

1, Foundation Preparation: Ensure the surface of the foundation soil is smooth, free of major irregularities, and remove any sharp objects that could damage the geotextile.

2, Specifications and Performance: Choose geotextile with appropriate specifications and performance to meet the design requirements of the project. Different types of geotextiles may be needed for different project environments and requirements.

3, Installation Method: Follow the specified installation method and standards, ensuring that the geotextile is stretched and fixed according to specifications. Overlapping edges sufficiently is typically required to ensure the continuity of the entire coverage layer.

4, Seam Treatment: If it is necessary to connect two pieces of geotextile in the project, use suitable seam materials and methods to ensure the strength and impermeability of the seam are not compromised.

5, Fixing Method: Geotextile is usually fixed using iron nails, ground staples, or other fastening materials. Ensure that the fixing method is secure to prevent displacement or damage during construction or use.

6, Construction Environment: In adverse weather conditions such as strong winds or heavy rain, suspend geotextile installation to avoid compromising the quality of the installation. Keep the construction site clean to prevent debris from damaging the geotextile.

As we can see from the above picture, this is our 6.3-meter Width Rapier Loom production line.

The raw materials used in this product are high-strength polypropylene, polyester, or nylon yarn. Typically, a majority of our customers prefer high-strength polypropylene yarn for woven geotextile fabric. The high-strength yarn undergoes twisting and additional twisting, and is then wound onto 7 rows of double-sided creels. Following the designated thread path, the warp yarn passes through steel healds, tension systems, and traction rollers before entering the rapier loom's heddles and steel healds. The weft yarn, guided by a weft feeder, undergoes reciprocating motion through the rapier, enabling the warp and weft yarns to intersect vertically, forming the fabric. After longitudinal trimming to remove selvages, elimination of loose threads, visual inspection, and final product packaging.
