The density of polypropylene fiber is only 0.91 g/m3 (that of polyester fiber is 1.38 g/m3), so polypropylene geotextile has larger coverage area under the same strength when using as polyester geotextile.

Polyester filament geotextile is a kind of geosynthetic material used in geotechnical engineering and civil engineering. It is made of polyester filament fiber; through netting and needling consolidation, its fibers are arranged into three-dimensional structures. In ad...
