Are Non-woven Geotextile

Non-woven fabrics mean that the production process does not require weaving, and geotextiles are used for geotechnical work. There are two types of non-woven geotextiles, one is needle-punched geotextile and the other is polyester filament geotextile. Geotextiles are mainly made of polyester and polypropylene. Its main function is to isolate building materials. It has good permeability, and a stable building structure, and can control various types of soil by changing the soil quality.

Geotextiles are also made from a water-permeable synthetic material made from fabric. The general product shape is ordinary, generally 4-6 meters wide and 50-100 meters long. Geotextiles are divided into ordinary geotextiles and special geotextiles. This product has the functions of water filtration, water conduction, barrier, reinforcement, leakage prevention, protection, etc., and is light in texture. It has good toughness and strength, but poor water absorption. Anti-high temperature, anti-cold, anti-aging, anti-oxidation. Non-woven fabrics can be widely used in road paving, slope protection, environmental greening, water conservancy, soil stabilization, and other fields.

According to its principle, structure, and method, it is divided into short fiber needle-punched geotextile (emphasis also called ordinary geotextile), special non-woven geotextile (woven geotextile also called filament geotextile), hand-woven geotextile, needle-punched geotextile cloth. Commercial geotextiles have the characteristics of antioxidant, high-temperature resistance, cold resistance, good toughness, ease of use, etc., and can be used on roads. railway. dykes. Maintenance, filtration, and reinforcement of hydraulic structures. A geotextile with a certain tensile strength is buried in the soil. The strength and stability of the soil are enhanced and inhibited through the interaction between the geotextile and the soil interface.
