Woven

Woven 1 Details:
     Woven fabric based on polypropylene, propylene Polyethylene flat yarn as raw material, by the two sets of parallel yarns (its shape is flat wire) composed of a group along a vertical loom (fabric direction of travel), said warp, another group lateral arrangement called the weft. Different weaving preparation equipment and processes will warp and weft interwoven woven into cloth-like, can be woven into different depending on thickness and density of the scope of use, generally thin woven geotextile to have very strong vertical and horizontal tensile intensity (greater than longitude and latitude), with good stability. In the wet state can maintain adequate strength and elongation. Also known as woven woven geotextile, woven geotextile.

Performance:
    1, the reinforcement effect: for roads, railways, airports, dams, breakwater, retaining wall backfill, side weirs and other rock engineering, soil stress increases soil dispersion member modulus limit soil pieces slip to improve stability.
    2, protective role: to prevent embankment by wind, waves, tide, rain erosion, and for revetment, slope, bottom protection, prevent soil erosion.
    3, filtration effect: for the dike, dam, river and coastal stone fast, slopes, retaining walls of the filter layer to prevent sand grains by allowing water or air to freely pass.
