How To Choose A Short-Filament Geotextile? The Ultimate Guide To Core Functions And Applications

  Short-filament geotextile is a key category of geosynthetic materials, manufactured through specialized processes including opening, carding, randomizing, web laying, and needle punching. It forms a stable three-dimensional interlocking fibrous network structure internally, combining excellent flexibility with high-strength mechanical properties. This allows it to closely adapt to complex terrain, effectively distribute external stress, and prevent localized damage, laying a solid and reliable performance foundation for various engineering applications.

Short-Filament Needle-Punched Nonwoven Geotextile

• Short-fiber geotextiles have high strength and excellent flexibility. They can maintain stable strength and elongation in both dry and wet environments, closely adhering to complex terrains and providing reliable protection.

• Resistant to acid and alkali corrosion, it can be used stably for a long time in environments with different levels of acidity and alkalinity. It is resistant to aging and microbial erosion at the same time, can resist ultraviolet rays and insect damage, and significantly extends the service life.

• It has outstanding water permeability and filtration performance. The fiber pores can quickly drain water to prevent damage from water accumulation. It can effectively intercept soil particles, fine sand and other impurities, prevent soil erosion and ensure the stability of the engineering structure.

  
  

Short-filament geotextile application fields

• In the field of transportation, short-fiber geotextiles are used for reinforcing highway subgrades, maintaining road surfaces, and reinforcing railway subgrades. They can disperse stress, reduce settlement, prevent crack propagation, enhance subgrade stability, and extend the service life of roads.

• In water conservancy projects, it plays a core role in anti-seepage, filtration and drainage, which can reinforce DAMS, enhance the anti-seepage performance of reservoirs, regulate rivers, prevent seepage collapse and river blockage, and improve flood control capacity.

• In the field of environmental protection, landfill sites use it as an isolation and anti-seepage layer to prevent leachate from polluting soil and groundwater. Impurities and suspended solids can be filtered in sewage treatment plants, improving the efficiency and quality of sewage treatment.

• In the field of agriculture and horticulture, it can improve soil quality, retain water and prevent evaporation, be used for anti-seepage protection of fish ponds, and also retain moisture and prevent weeds in landscaping, enhancing the environmental quality of green areas.
