The filament geotextile can be processed with polyester, vinylon, viscose fiber and other fibers, and also can be used with textile waste. The size range of filament geotextile is 2.78 ~ 13.3 dtex. When the needle punched geotextile is used as the isolation layer, the load is not large, and the strength requirement of the material is not high. Moreover, the short fiber needle punched filament geotextile has a large elongation and is not easy to break. The use of short fiber geotextile not only has the function of isolation, but also can lead the water in the building along the plane of geotextile.
After years of tempering, filament geotextile has developed into a popular waterproof material.

Performance characteristics of polyester filament geotextile: hatching eclosion
Polyester is a kind of geosynthetic material applied in geotechnical engineering and civil engineering. It is made by the method of polyester filament netting and consolidation, and its fibers are arranged into three-dimensional structure. In addition to good mechanical properties, it also has good vertical and horizontal drainage performance, good elongation performance and high chemical stability such as biological, acid and alkali resistance, aging resistance and so on. At the same time, it also has a wide range of pore size, tortuous pore distribution, excellent permeability and filtration performance.
Application of polyester filament geotextile:
Water conservancy project dike and slope protection filter, channel isolation, seepage control.
Foundation isolation, filter, drainage, soil slope, retaining wall and Pavement Reinforcement and drainage of highway, railway and airport runway.
Soft foundation treatment of port engineering, reinforcement and drainage of beach dike, harbor wharf and breakwater.
Polyester filament geotextile has been widely used in the field of infrastructure construction, and gradually applied to a wider range of fields.
The characteristics and technical characteristics of filament geotextile are as follows
Filament geotextile: filament geotextile is polyester filament needle punched non-woven geotextile, without chemical additives and heat treatment, and is an environmental protection building material. It can replace the traditional engineering materials and construction methods, make construction safer, and help environmental protection, and can solve the basic problems in engineering construction more economically, effectively and persistently.
Hualong filament geotextile has good mechanical function, good water permeability, corrosion resistance and anti-aging. It has the functions of isolation, filtration, drainage, protection, stabilization and reinforcement. It can adapt to uneven base, resist external damage and creep, and can maintain its original function under long-term load.
The characteristics of filament geotextile are as follows
Strength - under the same weight, the tensile strength in each direction is higher than that of other needle punched nonwovens.
Anti UV light - very high UV resistance.
Extreme high temperature resistance - high temperature resistance up to 230 ℃. The structure is intact and the original physical properties are maintained at high temperature.
Permeability and plane drainage: the geotextile is thick and needle punched, which has good plane drainage and vertical permeability, and can still maintain this performance after many years.
Creep resistance - the creep resistance of geotextile is better than other geotextiles, so it has good long-term performance. It is resistant to corrosion of common chemicals such as gasoline and gasoline.
Ductility - geotextile has a good elongation under a certain stress, so that it can adapt to uneven and irregular base surface.
Technical characteristics of filament geotextile: the thick geotextile can ensure the three-dimensional porosity of geotextile, which is conducive to the realization of excellent hydraulic properties. The bursting strength of geotextile has great advantages, especially suitable for reinforcement of retaining wall and embankment. The index of geotextile is higher than the national standard, so it is an excellent reinforced material.
