Abstract

In this study, three-dimensional woven geotextiles with special cords were fabricated using different yarns, and then, the effect of pore structure on the water permeability of these geotextiles was evaluated and analyzed. Weft overlapping structure might have resulted in increased water permeability by creating channels for the fluid to flow. When multifilaments are used, the woven geotextiles exhibit poor air and water permeability despite the large AOS (apparent opening size). This phenomenon is attributed to the spreading of multifilaments by compression. In comparison, the split yarn showed the better air and water permeability under identical conditions. For improving the mechanical properties, it is recommended the higher denier split yarn need to be used for the better water permeable property.
