We often say that the filament geotextile is polyester filament needle punched non-woven geotextile, which is also called polyester filament non-woven geotextile. It does not contain chemical additives and does not undergo heat treatment. It is an environment-friendly building material. It can replace the traditional engineering materials and construction methods, construction is more safe, and contribute to environmental protection, more economic, effective, lasting solution to the basic problems in engineering construction.
Filament non-woven fabric has good mechanical function, good water permeability, can be used for uneven base, and can resist corrosion, anti-aging, isolation, reverse osmosis, drainage, protection, stabilization, reinforcement and other functions. It can resist external damage caused by construction, creep is small, and it can still maintain its original function under long-term load. In addition, the filament non-woven fabric has a very high UV resistance and high temperature resistance. It still maintains its structural integrity and original physical properties at high temperature. It has been widely used in the field of infrastructure construction and gradually applied to a wider range of fields.
As a kind of geotextile with excellent performance, filament non-woven fabric mainly plays a protective role in engineering, and is widely used in water conservancy anti-seepage engineering, such as anti-seepage, plugging, reinforcement of rivers, lakes, reservoirs, dams, anti-seepage of canals, vertical core wall, slope protection, etc. It is used in municipal environmental protection, sanitation and anti-seepage engineering, such as sewage treatment, toxic and harmful materials treatment plant, domestic waste landfill, industrial waste, dangerous goods warehouse, construction and blasting waste, etc; Anti seepage and waterproof works of municipal engineering, such as underground works and roof reservoir of buildings, lining of sewage pipe, anti-seepage of roof garden, subway, etc; Landscaping waterscape seepage control works, such as golf course pond lining, artificial lake, pond, slope protection, etc; Agricultural water conservancy anti-seepage engineering, aquaculture industry, metallurgy and petrochemical industry anti-seepage, anti-corrosion engineering, mining industry anti-seepage, anti-corrosion engineering, traffic infrastructure anti-seepage engineering, etc.
