Polyester-Long-Filament Geotextile

Short Description:

Polyester filament geotextile is made by polyester filament mesh and consolidation, with fibers arranged in a three-dimensional structure.In addition to the good mechanical performance, it also has a good vertical and horizontal drainage performance and good extension performance and high biological resistance, acid and alkali resistance, aging resistance and other chemical stability energy.At the same time, it also has a wide aperture range, tortuous pore distribution, excellent permeability and filtration performance.

Product Characteristics

Polyester filament nonwoven geotextile has excellent heat resistance and light resistance.Even with short-term exposure at near 230°C, its performance barely unchanged.After extensive experiments and practice have proved that polyester long fiber unwoven textile fabric has long-term corrosion resistance to a variety of natural soils, moisture and microorganisms.

Product Function

Can of permanent isolation
Soil layers composed of different components and properties can be isolated and prevent mixing; with frost resistance and bearing requirements required for construction.

Good reverse filter performance and anticorrosion performance
The water can penetrate in all directions without accumulating pressure.At the same time can prevent soil loss, is conducive to stability and anticorrosion properties.

Reliable drainage performance
Due to the fluffy of its structure, the drainage of the geotechnical surface can be effectively controlled.

Good protection performance
Due to its good resistance, elongation and fluffy, the waterproof layer is effectively protected from potential mechanical damage.

It has reinforcement performance
Puffiness and high strength improve the overall stability of the project and improve its strength.
