Staple Fiber Needle Punched Geotextile
Staple fiber needle-punched nonwoven geotextile is made of polypropylene or polyester staple fiber as the main raw material, and is produced through processes such as opening, combing, tangling, laying, and needle punching. This product has the characteristics of excellent water permeability, filterability, durability, etc., and has high mechanical properties such as tensile strength, tear strength, and bursting strength.
Staple fiber needle-punched geotextiles can be widely used in water conservancy, hydropower, roads, railways, ports, airports, sports venues, tunnels, coastal tidal flats, environmental protection and other fields, playing the role of isolation, filtration, drainage, reinforcement, protection, sealing, etc.
1. Staple-fiber needle-punched geotextiles isolate building materials with different physical properties, so that two or more materials do not flow or mix, maintain the overall structure and function of the materials, and enhance the load-bearing capacity of the structure.
2. When water flows from the fine soil layer to the coarse soil layer, the good air permeability and water permeability of the needle-punched geotextiles are used to allow water to flow through, and effectively intercept soil particles, fine sand, small stones, etc., to maintain the stability of water and soil engineering.
3. Staple-fiber needle-punched geotextiles are good water-conducting materials. They can form drainage channels inside the soil and remove excess liquid and gas in the soil structure.
4. Staple-fiber needle-punched geotextiles are used to enhance the tensile strength and deformation capacity of the soil. Needle-punched geotextiles increase the stability of the building structure to improve the quality of the soil.
5. Staple-fiber needle-punched geotextiles effectively diffuse, transmit or decompose concentrated stress, and needle-punched geotextiles prevent the soil from being destroyed by external forces.
6. Staple fiber needle-punched geotextiles are combined with other materials (mainly asphalt or geomembrane) to form an impermeable barrier in the soil layer of the needle-punched geotextiles (mainly used for road resurfacing and repair, etc.)
7. Staple fiber needle-punched geotextiles can be widely used in water conservancy, hydropower, roads, railways, ports, airports, sports venues, tunnels, coastal beaches, reclamation, environmental protection and other fields, playing the role of isolation, filtration, drainage, reinforcement, protection, and sealing.
