(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.
