Polypropylene filament geotextile adopts advanced spinning equipment, the monofilament fineness can reach above 11dex, the strength can reach above 3.5gd, the mesh is evenly laid without cloud spots, the vertical and horizontal strength and elongation are consistent, and the product performance is more uniform and stable.
Polypropylene spunbond needle-punched geotextile has superior physical properties and good chemical stability, therefore, it is suitable for any geotechnical engineering, especially in acid and alkaline environments. Such as: highways, railways (high-speed rail), airports, seaports, landfills, tailings dams, fly ash landfills, ash dam pools, artificial wetlands, rivers, lakes and seas, reservoirs, canals, land reclamation, sewage governance and other projects.
(1) The density of polypropylene is small, only 0.91g/cm3( polyester is 138g/cm3), so compared with polyester geotextile, polypropylene geotextile has a larger coverage area under the same strength. (2) The special structure of polypropylene makes it have excellent acid and alkali resistance, especially the alkali resistance is better than that of polyester. in polyester.
(3) The surface friction coefficient of polypropylene fiber is small, the friction force between fibers is small, and the wear resistance is good, and the anti-vibration friction performance is much better than that of polyester
(4) Polypropylene has good hydrophobicity, does not absorb water, and is used in water supply and drainage. Engineering applications are better than polyester.
(5) The polypropylene fiber needle-punched geotextile has higher strength than the
polyester needle-punched geotextile of the same weight, and the vertical and horizontal strengths are equal.
(6) The polypropylene geotextile produced by our company can realize the compounding of polypropylene non-woven fabrics with different deniers, and the filtration effect is better.
