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 perfor- mance of these nonwoven geotextiles was reviewed by using Arrhenius' equation and the result were compared to con- sider their applicability as filter material. |
