Woven Geotextile is a special geosynthetic material, and its weaving process is unique in improving its overall mechanical properties.
Material selection:
Woven Geotextile usually uses high-strength, high-modulus synthetic fibers such as polyester, polypropylene or nylon. These materials have excellent tensile strength, durability and chemical stability, and can meet various harsh environmental conditions in civil engineering.
Weaving structure:
Warp knitting structure: This is a common weaving method in which the warp yarns cross each other at a certain angle to form a grid structure. Warp knitted geotextiles have high longitudinal and transverse strength and stability, and are suitable for occasions that need to withstand multi-directional stress.
Weft knitting structure: In this structure, the yarns are connected along the weft direction to form a continuous loop. Weft knitted geotextiles have good elasticity and extensibility, and are suitable for occasions that require certain buffering properties.
Plain weave structure: The interlaced weaving of warp and weft yarns forms a flat cloth surface. Flat woven geotextiles have good planar stability and low water permeability, and are suitable for filtration and isolation functions.
Reinforced weaving technology:
Double-layer weaving: By adding a layer to the single-layer weaving to form a double-layer structure, the strength and durability of the geotextile can be significantly improved.
Reinforced weaving: Adding reinforcements, such as high-strength fiber bundles or metal wires during the weaving process can greatly improve the tensile and tear resistance of the geotextile.
Surface treatment:
Coating treatment: Coating a layer of polymer, such as polyurethane or asphalt, on the surface of Woven Geotextile can improve its waterproofness and weather resistance.
Heat setting treatment: By heat treating the woven geotextile, the fiber molecular structure can be made more stable, thereby improving the overall strength and dimensional stability of the material.
Finishing process:
Calendering treatment: Calendering the geotextile through a calender can improve its surface smoothness and glossiness, while enhancing its mechanical properties.
Prestressing treatment: Applying prestress during the production process can better align the fiber molecules, thereby improving the strength and modulus of the geotextile.
Quality Control:
Tension Control: Strictly control the tension of the yarn during the weaving process to ensure uniform weaving and avoid local stress concentration.
Density Adjustment: Adjust the weaving density according to the design requirements to obtain the required porosity and permeability.
Through the uniqueness of the above weaving process, Woven Geotextile is able to achieve excellent mechanical properties, including high strength, high modulus, good dimensional stability and durability, which make it widely used in civil engineering, water conservancy engineering, transportation engineering and other fields.
