Product Introduction
PP filament nonwoven geotextile
(1) The polypropylene has a low density of only 0.91 g/m3 (polyester is 1.38 g/m3), so the polypropylene geotextile has a larger coverage area under the same strength as the polyester fabric.
(2) The special structure of polypropylene makes it have excellent acid and alkali resistance, especially the alkali resistance is better than polyester. It is effective when used in the protection, strengthening, waterproofing and anti-corrosion engineering of underground soil with strong acidity and alkalinity than polyester.
(3) The surface friction coefficient of polypropylene fiber is small, the friction between fibers is small, and the wear resistance is good, and the anti-vibration friction performance is much better than polyester.
(4) Polypropylene has good hydrophobicity, no water absorption, and is superior to polyester in water supply and drainage engineering.
(5) Acrylic fiber needle-punched fabric is stronger than the same weight of polyester needle-punched geotextile, and the vertical and horizontal strength is equal.
