FILTRATION PERFORMANCE OF TWO-LAYERED NONWOVEN GEOTEXTILES

摘要：

Nonwoven geotextiles have been widely used for separation, filtration, reinforcement and drainage systems. The filtration and drainage functions are especially attractive in the construction of soil structures. In this paper, five two-layered nonwoven geotextiles with different needling density have been developed to study their filtration performance. The experimental results show that needling density has obvious effects on the filtration performance of nonwoven geotextiles. Regarding the five samples in this study, the one with needling density of 470 p/cm2 has the best filtration performance.
