Filament anti-sticking needled nonwoven geotextile is a kind of geotextile with three-dimensional pores, which is made from polyester chips by using melt spinning, air flow forming and needled consolidation process. Filament geotextile: Filament geotextile is polyester filament needle-punched non-woven geotextile, which does not contain chemical additives and is not subject to heat treatment. It is an environment-friendly building material. It can replace the traditional engineering materials and construction methods, make the construction safer, help to maintain the environment, and solve the basic problems in engineering construction more economically, effectively and durably.

Filament geotextile has outstanding mechanical function, good water permeability, corrosion resistance, aging resistance, barrier, filter, drainage, maintenance, stability, reinforcement and other functions, can get used to uneven bottom layer, can resist external construction force damage, creep is small, and can still adhere to the original function under long-term load.

Characteristics of filament geotextile:

Strength - under the equal weight specification, the tensile strength of each direction is higher than that of other needled non-woven fabrics.

Anti-ultraviolet light - with extremely high anti-ultraviolet ability.

Extremely high temperature resistance function - high temperature resistance up to 230 ℃, and still adhere to the structural integrity and original physical function under high temperature.

Permeability and plane drainage - The geotextile is thick and needled, and has excellent plane drainage and straight water permeability. It can still adhere to this function after many years.

Creep resistance - The creep resistance of geotextile is better than that of other geotextiles, so it has good long-term effect. It can resist the erosion of common chemical substances in soil and the corrosion of gasoline, diesel, etc.

Ductility - The geotextile has good elongation under certain stress, so that it can be used to the uneven and irregular base surface.

Technical features of filament geotextile: the geotextile is thick, which can ensure the three-dimensional vacancy rate of geotextile, and is conducive to the realization of hydraulic function.

The bursting strength of geotextile has great advantages, especially suitable for retaining wall and embankment reinforcement.
