Non Woven Geotextile application

Release time:

2024-11-15

Filament geotextile is a geosynthetic material with excellent performance and wide application, which plays an important role in civil engineering and environmental protection engineering.

Filament geotextile is a kind of geosynthetics commonly used in civil engineering and environmental protection engineering. The following is a detailed introduction to filament geotextile:

1. Definition and production process

Definition: Filament geotextile is a fabric made of polymer chips (such as polyester chips or polypropylene particles) through spinning, laying nets, needle punching reinforcement and other processes. It can also be called polyester filament needle punched non-woven geotextile.

Production process:
Raw material selection: Use high-quality polyester chips or polypropylene particles.

Mixed molding: Mix the raw materials with additives at high temperature and form filament bundles through a spinneret.

Molding treatment: Place the filament bundle on the oriented mesh belt, and after four-roll spiral pressure, cooling and stretching treatment, form the finished filament geotextile.

Subsequent processing: The finished product can be coated, composited and processed to meet specific application requirements.

2. Main features

High strength: Filament geotextile has excellent tensile strength and can withstand large external forces.

Weather resistance: It has good UV resistance and high temperature resistance, and can remain stable under harsh climatic conditions.

Corrosion resistance: Good corrosion resistance to common chemicals in the soil, as well as gasoline, diesel, etc.
Drainage performance: Good plane drainage and vertical permeability, can effectively remove excess liquid inside the soil.
Ductility: Good elongation under certain stress, can adapt to uneven irregular base surface.

3. Application fields
Filament geotextiles are widely used in various civil engineering and environmental protection projects, including but not limited to:

Water conservancy projects: used for dam and slope filtration, channel isolation and anti-seepage, etc.
Road engineering: used for road foundation isolation, anti-filtration, drainage and road reinforcement, etc.
Railway engineering: used for railway roadbed reinforcement, isolation, anti-seepage and anti-corrosion, etc.
Environmental engineering: used for soil stabilization, landfill coverage, yard coverage, etc.
Mining engineering: used for mine waste treatment, slope reinforcement and anti-seepage, etc.
Governance engineering: used for river regulation, soil erosion control and wind and sand fixation, etc.

4. Technical standards and parameters
The technical standards and parameters of filament geotextiles usually follow the national standard GB/T 17639, which specifies the various performance indicators of filament geotextiles, such as unit area mass deviation, thickness, width deviation, breaking strength, bursting strength, etc. The specific technical parameters may vary depending on product specifications and application requirements.

5. Precautions
When using filament geotextiles, appropriate specifications and models should be selected according to specific project requirements.
During the construction process, it should be ensured that the filament geotextile is laid flat and without damage, and the operation should be carried out strictly in accordance with the construction specifications.
Regularly inspect and maintain the filament geotextile to ensure its long-term stable operation.

In summary, filament geotextile is a geosynthetic material with excellent performance and wide application, which plays an important role in civil engineering and environmental protection engineering.
