What is non-woven geotextile and its functions and characteristics

Non woven geotextiles are arranged into a mesh through different equipment and processes. By using techniques such as needling, different fibers are interwoven and fixed to standardize the fabric, making it soft, full, thick, and hard to meet the requirements of different thicknesses. Non woven geotextiles have good fabric gaps and adhesion. Due to the softness of the fibers, they have certain tear resistance and good deformation adaptability, as well as good leveling and drainage ability. The surface is soft with many gaps. A good friction coefficient can increase the adhesion ability of soil particles, prevent small particles from passing through, prevent particle loss, and eliminate excess moisture. Soft surface and good protective ability. According to the length of the silk used, it can be divided into long filament non-woven geotextiles or short filament non-woven geotextiles. They can all have good filtering, isolation, reinforcement, protection and other effects, and are a widely used geosynthetic material. The tensile strength of long fibers is higher than that of short fibers, and can be selected for use according to specific requirements.

Mainly made of high-quality polyester short fibers (fibers 4-9dtex, length 50-76mm), it can also produce needle punched non-woven geotextiles of polypropylene, nylon, vinylon or mixed fibers according to requirements. It has the functions of 1. isolation, 2. filtration, 3. drainage, 4. reinforcement, 5. protection, and 6. sealing.

Geotextile has good air and water permeability to let water flow through it so as to effectively control sandrock running-down.
Geotextile has good water transmissibility, it can form drainage channels inside soil mass to drain redundant liquid and air out of the soil mass.
Geotextile helps to enhance the soil mass' tensile strength and non-deformability and structural stability so as to improve soil mass quality.
It can effectively make the concentrated stress diffuse, transfer or decompound, and prevent the soil mass against the destruction of outside force.
It can prevent the mixture of sandstone, soil mass and concrete of upper and lower layers.
Its mesh is hard to jam by virtue of the compliancy and motility of the reticulation formed by indefinite form fibrous tissue.
High water permeability-it can keep good water permeability even in the pressure of soil and water.
Corrosion resistant-it is made from polypropylene fiber or terylene or other chemical fiber, featuring resistance to acid and alkali and oxidation, non-corroding, no worm-eaten.
Easy construction-low weight, easy operation, simple construction.
