Woven geotextile is composed of at least two groups of parallel yarns (or flat filaments). One group is called warp along the longitudinal direction of the loom (the direction of fabric travel), and the other group is called weft. Warp and weft yarns are woven into cloth shape with different weaving equipment and processes. They can be woven into different thickness and compactness according to different application ranges. Generally, the spun geotextile is thin, has strong tensile strength in both vertical and horizontal directions (longitude is greater than latitude), and has good stability.
