(1) polypropylene density is small, only 0.91 g / m3 (polyester is 1.38 g / m3), so the polypropylene geotextile than polyester geotextile, under the same strength, with a greater coverage area.
(2) the special structure of polypropylene to make it has excellent acid and alkali resistance, especially alkali resistance is better than polyester, in the soil alkaline strong underground protection, strengthening, waterproof, anti-seepage and other projects When the effect is better than polyester.
(3) polypropylene Geotextile Fabrics surface friction coefficient is small, the friction between the fibers is small, and good wear resistance, anti-vibration friction performance is much better than polyester.
(4) Polypropylene has a good hydrophobic, non-absorbent, in the water supply and drainage project is better than polyester.
(5) Polypropylene fiber acupuncture geotextile than the same weight of polyester acupuncture geotextile strong, and vertical and horizontal strong equal.
(6) I produced the polypropylene geotextile, can achieve different denier polypropylene nonwoven fabric compound, the filter effect is better.
