Polypropylene woven fabric is a kind of geotextile. Polypropylene woven fabric has excellent water permeability, filterability, durability, and can be widely used in railways, highways, sports halls, dams, hydraulic constructions, tunnels, beaches, reclamation, environmental protection and other projects.
Polypropylene woven fabrics Mainly include staple fiber needle punched non-woven polypropylene geotextile and split-membrane woven polypropylene geotextile. Geotextile, also known as geotextile, is a permeable geosynthetic material made of synthetic fibers through needle punching or weaving.
The role of polypropylene geotextile:
①Using the good air permeability and water permeability of polypropylene geotextile to allow water to pass through, thereby effectively intercepting sand and soil loss. Effectively diffuse, transfer or decompose concentrated stress to prevent soil from being damaged by external forces.
② Prevent the mixing of the upper and lower layers of sand, gravel, soil and concrete. The mesh is not easy to be blocked, and the network structure formed by the unshaped fibrous tissue has strain and mobility.
③ High water permeability, it can still maintain good water permeability under the pressure of soil and water.
④Corrosion resistance, using polypropylene or polyester and other chemical fibers as raw materials, acid and alkali resistance, no corrosion, no insects, and anti-oxidation.
⑤Simple construction, light weight and convenient use.
