Long Filament Nonwoven Geotextile
Long Filament Nonwoven Geotextile is a new type of building material, made from synthetic fibers of high molecular weight polymers such as polyester, polypropylene, acrylic, and nylon. Long filament spunbond needle punched geotextile has multiple functions such as anti-seepage, filtration, drainage, isolation, reinforcement, protection, and sealing. Compared with conventional masonry and concrete materials, it has the advantages of low investment, simple construction process, short construction period, good anti-seepage effect, and high effective utilization coefficient of channels.
PRODUCT DETAILS
Application scope
Long Filament Nonwoven Geotextiles have good mechanical properties, as well as good longitudinal and transverse drainage performance, good elongation performance, and high chemical stability properties such as biological, acid and alkali resistance, and aging resistance. At the same time, it also has a wide range of pore sizes, a tortuous pore distribution, excellent permeability and filtration performance. Polyester filament geotextile has been widely used in the field of infrastructure construction and gradually applied to a wider range of fields.
Product Features
Geotextile has high strength. Due to the use of plastic flat wires, it can maintain sufficient strength and elongation in both dry and wet conditions, and is corrosion-resistant. It can withstand corrosion for a long time in soil and water with different acidity and alkalinity. Its permeability is good because there are gaps between the flat wires, so it has good water permeability. Long filament geotextile is a geosynthetic material used in geotechnical and civil engineering. It is made by networking and consolidating polyester filaments, and its fibers are arranged into a three-dimensional structure. In addition to having good mechanical properties, it also has good longitudinal and transverse drainage performance, good elongation performance, and high chemical stability such as biological, acid and alkali resistance, and aging resistance. At the same time, it also has a wide range of pore sizes, a tortuous pore distribution, excellent permeability and filtration performance.
