Polypropylene filament spunbond needle-punched geotextile
Polypropylene filament spunbond needle-punched geotextile is made of polypropylene filament yarn, which is processed by spinning equipment, air-laid net equipment, and needle-punched equipment.
Polypropylene filament spunbond needle-punched geotextile has the advantages of high strength, strong puncture resistance, corrosion resistance, anti-microbial, aging resistance, high temperature resistance, excellent water permeability, filterability, soil retention and so on. Compared with polyester filament geotextile, it has higher strength, stronger tear resistance and puncture resistance, especially acid and alkali resistance. It can be in long-term contact with alkaline materials such as cement, fly ash, lime, etc. It maintains stable performance without hydrolysis.
Mainly used in high-speed railway ballastless track isolation layer, tunnel anti-seepage liner layer, airport runway isolation layer, highway waterproof and crack-proof base fabric, water conservancy engineering bank protection bottom, waste landfill, emergency engineering foundation treatment, ecological slope protection and other engineering fields .
