Woven geotextile fabrics are also the weaving fabrics we often say. It is made up of two or more sets of mutually perpendicular yarns, which are interwoven with warp and weft at a 90 degree angle. The yarn in the length direction of the cloth is called warp yarn, and the yarn in the transverse direction is called weft yarn. When judging the warp and weft yarns, it is generally necessary to look at the edge of the cloth, and the direction of the parallel cloth is the warp yarn. If it is a small piece of borderless cloth, the warp yarn is coarse and the weft is fine.
The geotextile materials are mainly polyester (PET) and polypropylene (PP), which are characterized by light weight, high breaking strength, small elongation at break, good overall performance and good aging resistance.
2.Product Feature
(1) high strength: it is made from polypropylene, polyester, polyamide and other synthetic fibers used in high strength industry, with high original strength.After woven into regular interwoven structure, the comprehensive bearing capacity is further improved.
(2) durability: synthetic chemical fiber is characterized by non-deformation, non-decomposition and non-weathering.Can maintain its original characteristics for a long time.
(3) corrosion resistance: synthetic chemical fiber generally has acid resistance, insect resistance and mold resistance.
(4) water permeability: the geotextile fabric can effectively control its structural pores and has reached a certain water permeability.
(5) convenient storage and transportation: due to its light weight, it can be packed as required, so transportation, storage and construction are very convenient.

4.Project Cases
Due to its high strength and low elongation, the filament woven geotextile can be used for the protection, reinforcement and isolation of soft drainage and geotechnical engineering of all dams.
