·Light in weight. Density of polypropylene products is 0.91 g/cm3 (polyester is 1.38 g/cm3), so the polypropylene geotextile has a larger coverage area of the same quality geotextile under the same strength as the polyester geotextile.
·Good chemical stability. Polypropylene has excellent acid and alkali resistance, especially alkali resistance is superior to polyester. Polyester geotextiles are prone to irreversible hydrolysis under alkaline conditions or in the presence of large amounts of water, resulting in a loss or even complete loss of material properties, especially for areas that are in direct contact with alkaline interfaces such as cement, lime, and saline-alkali, while polypropylene Geotextiles are fully applicable to the above environment and do not pollute the environment.
·High mechanical properties. Polypropylene spunbonded needle-punched geotextile is made up of continuous polypropylene filaments. The tensile fracture form of the fabric is mainly the fiber breakage, while the staple fiber geotextile is mainly the extraction between the fibers. Therefore, strength,elongation and other mechanical properties of polypropylene spunbonded needle-punched geotextiles are better than staple fiber geotextile
·Good drainage performance. Polypropylene has excellent hydrophobicity, but has good water-conducting effect, and is superior to polyester in drainage engineering.
·The filtering effect is good. The polypropylene geotextile produced by our company can realize the compounding of different denier polypropylene non-woven fabrics, forming double-layer filtration and better filtering effect.
·Convenient construction. Polypropylene spunbond needle-punched geotextile has low needle density, soft and non-rigid cloth surface, and is more suitable for use. It is more convenient to lay and install.
In virtue of the superior physical properties and good chemical stability of PP geotextile, it can be applied to any geotechnical engineering environment,especially the environment with acid and alkali, such as highway, railway (HSR), airport, seaport, landfill, tailings dam, fly ash landfill, ash dam pool, artificial wetlands, rivers and lakes governance, reservoirs, canals, land reclamation, sewage treatment works etc.
