The fibers used in polypropylene staple fiber filament geotextiles are geotechnical materials made of ultra-high-strength polypropylene short fibers as the main raw material, which are carded, laid, needle-punched, and post-treated. Polypropylene staple fiber geotextile has the characteristics of high strength, aging resistance, acid and alkali resistance, abrasion resistance, good flexibility, simple construction and so on.

Features of polypropylene staple fiber filament geotextile:

Isolation: Allow water to pass through, so as to intercept the loss of sand and soil and prevent the mixing of sand, gravel, soil and concrete in the upper and lower layers;

Reinforcement: enhance the reinforcement function, enhance the tensile strength and deformation resistance of the soil, enhance the stability of the building structure, and improve the quality of the soil; protect and buffer, diffuse and transfer concentrated stress, and prevent the soil from receiving external forces Effect and destroy;

Filtration and drainage: It can still maintain good water permeability under the pressure of soil and water, and form drainage channels inside the soil to discharge excess liquid and gas in the soil structure;

Corrosion resistance: Polypropylene staple fiber is used as raw material, acid and alkali resistance, no corrosion, no insects, no oxidation; simple construction: light weight, easy to use.
