With polypropylene, polypropylene & polyethylene fiber ribbon-like filament as raw materials, woven geotextile of Shandong Tianhai is made of at least two rows of parallel yarns (or ribbon-like filaments), of which one vertical row goes along the weaving machine (the direction of the textile goes) is called warp, the other horizontal one weft. Users can use different weaving machines and technologies to weave the warps and wefts into textile-shape with various thickness and compactness according to usage ranges. In general, woven geotextile is comparatively thin with relatively strong tensile strength both vertically and horizontally (the strength of the former is stronger than the latter) as well as brilliant stability.
