Needle punched non-woven geotextile can be divided into filament needle punched non-woven geotextile and staple needle punched non-woven geotextile. Needle punched non-woven geotextile is widely used on highways. In fact, it is also widely used in railway projects.
The specification of needle punched non-woven geotextile is determined on site, and the quality requirement is generally not less than 150g/㎡. Needle punched non-woven geotextile has been widely used in railway engineering laying, and the benefits of cost reduction and better quality have been achieved.
In recent years, we have found that filament needle punched non-woven geotextile is one of the high-end products in the production of pure polyester materials. It is applied and constructed according to the needs of railway projects, and the effect is recognized according to long-term use experience. Since the development of railway projects with filament geotextiles, China has created a rapid development of railway industry, and high-speed railways use one of the indispensable materials in impermeable and waterproof geotextiles.
It has excellent filtering, isolation, reinforcement and protection functions, high tensile strength, good permeability, high temperature resistance, freezing resistance, aging resistance, corrosion resistance and other good performance characteristics. In addition, the filament geotextile itself has good fabric gaps, good adhesion and separation. Because the fiber is soft, it has certain tear resistance, anti-seepage membrane force, good deformation adaptability, and good plane drainage capacity, The soft surface with many gaps has a good friction coefficient, which can increase the adhesion of soil particles, prevent the loss of particles and remove excess water by small particles. The soft surface has a good protection ability.
