Product Description

Polyester Filament Nonwoven Geotextile fabric

Polyester filament geotextile is made directly by spinning and needle-punching consolidation by polyester method, it is made through the method of forming and consolidating polyester filaments, and it's fibers are arranged in a three-dimensional structure. It has excellent heat resistance and light resistance. After a large number of experiments and practices, it has long-term corrosion resistance to various natural soils, moisture and microorganisms.

Lianxiang Non-woven filament Geotextile is Continuous Filament Needle punched made from Polyester. Provides effective solution of separation, filtration, drainage, protection and reinforcement functions for use in a variety of industries and applications

Application

• Filtration

when water passes from a fine-grained to a coarse grained layer, Non-woven Geotextiles can retain fine particles well. Such as when water flows from a sandy soil into a Geotextile wrapped gravel drain.
• Separation

to separate two layers of soil with different physical properties, such as the separation of road gravel from soft sub-base materials.
• Drainage

to drain liquid or gas from the plane of the fabric, which leads to draining or venting of the soil, such as the gas vent layer in a landfill cap.
• Reinforcement

to improve the load bearing capacity of a specific soil structure, such as the reinforcement of a retaining wall.

FAQ
1,Which is better woven or nonwoven geotextile?
Woven geotextiles are an excellent choice for reinforcement and stabilization applications, while nonwoven geotextiles are great for filtration, separation, and drainage applications.

2,What are nonwoven geotextiles?
Nonwoven geotextiles are multi-purpose fabrics that are felt-like in appearance. The main functions for these products are filtration and separation. 

3,What is non woven geotextile used for?
Non-woven geotextiles are chosen when both soil separation and permeability are required. These products are often used to wrap French drains or in conjunction with other sub-surface drainage solutions. Non-wovens are also typically used beneath rock riprap revetment, where both separation and drainage are critical.
