Geotextile has excellent filtering, isolation, reinforcement, and protection, high tensile strength, good permeability, high-temperature resistance, freezing resistance, aging resistance, and corrosion resistance.
Non-woven geotextiles are made of filaments or short fibers that are laid into a mesh through various tools and processes. After needle punching and other processes, different fibers are interlaced with each other, intertwined, and fixed to standardize the fabric and make the fabric soft, full, thick, and stiff to meet the requirements of different thicknesses. Non-woven geotextile has a good fabric gap and good adhesion and separation. Because the fiber is soft, it has a certain resistance to tearing and good deformation adaptability. At the same time, it has good flat exhaust ability. The surface is soft and has a good coefficient of friction. It can increase the adhesion of soil particles. This can prevent fine particles from passing through and prevent damage to particles while removing excess water. The surface is soft and has a very good coefficient of friction. Good protection ability. According to the length of the filament, it is divided into filament non-woven geotextile or short filament non-woven geotextile. They can play a very good role in filtering, isolation, reinforcement, protection, etc. It is a widely used geosynthetic material. The tensile strength of the filament is higher than that of the short filament and can be selected according to specific requ
Mainly high-quality polyester staple fiber (fiber 4-9dtex, length 50-76mm) can also be produced according to polypropylene, nylon, vinyl, or mixed fiber needle punch non-woven geotextile requirements. It has the function of: 1. Isolation; 2. Filtration; 3. Drainage; 4. Reinforcement; 5. Protection; 6. Closed.
Because non-woven geotextile has the above six functions, it can be widely used in railways, highways, sports venues, dams, hydraulic construction, tunnels, beaches, reconstruction, environmental protection, and other projects.
Features:
The raw materials used are mainly polyester, followed by polypropylene and vinyl, with a unit weight of 100-800 g/m2. Furthermore, it can also be used as a soil-reinforcing material to strengthen soft foundations or to create light-retaining walls. At the same time, it can also reduce the pore water pressure below the dam. The emergence of non-woven geotextiles is later than that of woven geotextiles. The main manufacturing methods of non-woven geotextiles are spunbond and needle-punched. The needle-punch method accounts for a larger proportion in my country. East one, three, seven, nine, one. Three. Two, one, or min It has been widely used to solve road erosion and mud runoff problems. It is used for the drainage system of earth-rock dams, underground drainage pipes, soft foundation reinforcement slope protection, and shoulder pads of various dams. Therefore, the development speed of non-woven geotextiles is very fast and it has become the main material of geotextiles. Non-woven geotextiles have a large expansion, can adapt to large deformations, can be made with appropriate size pores as needed, and have good penetration and exudation in both horizontal and vertical directions.
