Abstract

In this study, mechanical properties, such as tensile strength, tear strength, bursting strength, puncture strength, and transmissivity of nonwoven geotextiles were determined to evaluate their applicability as filter material in civil-engineering fields. For this purpose, spunbonded and needle punched nonwoven geotextiles were investigated according to their weight grade. The chemical resistance as a measure of the liquid resistance was analyzed on the basis of the strength retention with variable duration time under immersion condition. Finally, the long-term performance of these nonwoven geotextiles was reviewed by using Arrhenius' equation and the result were compared to consider their applicability as filter material.
