Polyester Filament Geotextile
1. Strength: under the same grammage specification, the tensile strength in all directions is higher than that of other needle punched nonwoven fabrics;
2. Ultraviolet light resistance: it has very high resistance to ultraviolet light;
3. High temperature resistance: high temperature resistance up to 230 ℃, high temperature still maintains the structural integrity and the original physical properties;
4. Permeability and plane drainage: geotextile is thicker and needle-punched moulding, it has good plane drainage and vertical permeability, and it can still maintain this performance after many years;
5. Creep resistance: geotextile has better creep resistance than other geotextiles and therefore has good long term performance. It is resistant to erosion by common chemicals in the soil as well as to corrosion by petrol, diesel etc;
6. Extensibility: geotextile has good elongation under certain stress, which enables it to adapt to uneven and irregular substrate;
Technical characteristics of filament geotextile: the geotextile is thicker, which can ensure the three-dimensional void ratio of the geotextile, which is conducive to the realisation of excellent hydrodynamic properties. The top-breaking strength of geotextile has great advantages, especially suitable for retaining wall and embankment reinforcement. The indexes of geotextile all exceed the national standard, which is excellent geotechnical reinforcement material.
Product description
Polyester filament geotextile is the use of polyester approach by spinning needle-punching solidification directly made of materials, with excellent heat-resistant, light-resistant properties.
Polyester filament nonwoven geotextile has excellent heat and light resistance properties. Even in nearly 20 ℃ environment of short-term exposure, its performance is almost no change. Polyester long-fibre non-woven geotextiles have been proven through extensive testing and practice to have long-term corrosion resistance to a wide range of natural soils, moisture and microorganisms.

Product Performance
1. Permanent isolation
Permanently isolates and prevents mixing of soil layers consisting of different components and properties;
It is frost resistant and has the necessary bearing requirements for construction.
2. Good anti-filtration and corrosion protection
Water can penetrate in all directions without building up pressure. At the same time, it can prevent soil loss, which is conducive to stability and anti-corrosion properties.
3. Reliable drainage performance
Due to its fluffy structure, it can effectively control the drainage of geotechnical engineering surface.
4. Good protection performance
Because of its good Kang puncture, extensibility and fluffiness, can effectively protect the waterproof layer from potential mechanical damage.
5. With reinforced performance
Fluffiness and high strength to improve the overall stability of the project and improve its strength.
Application
1. Anti-filtration of water conservancy project dam and slope protection, isolation and seepage control of channels;
2. Highway, railway, airport runway foundation isolation, anti-filtration, drainage, soil slopes, retaining walls and pavement reinforcement, drainage;
3. Soft foundation treatment of port engineering, beach embankment, harbour wharf and breakwater reinforcement, drainage;
4. Polyester filament geotextile has been commonly used in the field of infrastructure construction, gradually being applied to a wider range of fields.
