Geo Textile Geofabric UV Resistance Needle Punched Polypropylene Nonwoven Geotextile Fabric
About PP Nonwoven Short Fiber Geotextile
1. Material definition and characteristics
Basic composition
Made of short polypropylene (PP) fibers reinforced by needle punching process, it has a three-dimensional porous structure, and is both flexible and high-strength.
2. Key characteristics
- Physical properties: low specific gravity (0.191g/cm³), only 66% of PET; high tensile strength (longitudinal ≥4.5CN/dt), elongation ≥300%.
- Durability: anti-corrosion, anti-aging, acid and alkali resistant, and can be exposed to ultraviolet light for a long time (some products are treated with TiO₂ impregnation to enhance anti-ultraviolet performance).
- Functional characteristics: good water permeability, which can realize the free flow of water/air, while isolating soil particles and preventing the loss of structural layers.

Yixing Shenzhou Partial Typical engineering cases for PP Nonwoven Geotextile used in Railway project
1. Suiyu Railway Test Section
Our country used geosynthetics in ballastless track for the first time, verifying the feasibility of polypropylene geotextile in the sliding layer.
2. Beijing-Shanghai High-speed Railway and Wuhan-Guangzhou High-speed Railway
CRTSⅠ/Ⅱ type slab track is widely used, and polypropylene geotextile is used as the key material of the isolation layer and sliding layer.
3. Zhengzhou-Xuzhou Passenger Dedicated Line
CRTSⅢ type track slab was used on a large scale for the first time, with 700g/㎡ high-strength polypropylene geotextile, marking the maturity of domestic production technology.
