Features a non-woven, high strength, due to the use of plastic fibers in wet state can maintain sufficient strength and elongation. 2, corrosion resistance, at different pH of soil and water can be permanently resistant to corrosion. 3, permeable fortunately there are gaps between the fibers, so it is good water permeability. 4, anti-microbial resistance to micro-organisms, insects are not compromised. 5, the construction is convenient, since the light weight, soft, and therefore transportation, laying and easy construction. 6, complete specifications: width up to 9 m. Is currently the most wide product mass per unit area: 100-1000g / m nonwoven Feature: 1. High intensity: the use of high strength industrial polypropylene, polyester, nylon and other synthetic fiber as raw material, with high raw strength. After weaving into a law interwoven structure, the overall carrying capacity further. 2. Durability: synthetic fiber is characterized by easy denaturation, decomposition, weathering. Can long maintain its original characteristics. 3. corrosion: Synthetic Fiber general with acid and alkali resistance, moth-eaten, mold-resistant. 4. permeability: woven fabrics can be effectively controlled pore structure, in order to achieve certain permeability. 5. Storage easy: because of its light weight, according to certain requirements of the packaging, it is very easy to transport, storage, construction and the like. Non-woven Function: ■ use of geotextile good air permeability and water permeability, so that water flows through, it will effectively retain sand loss. ■ Geotextile has good conductivity properties of water, it can drain passage formed inside the soil, the internal structure of the soil efflux of excess liquids and gases. ■ use of geotextile reinforced soil tensile strength and resistance to deformation, enhance the stability of the building structure in order to improve soil quality ■ effective stress will focus on proliferation, transfer, or decomposition, to prevent soil and damage by external force. ■ prevent mix between sand and gravel, soil and concrete on the lower deck. ■ mesh plug is not easy - because they do not shape reticular formation of fibrous tissue and motion of a contingency. ■ High permeability - under the pressure of water in the soil, can still maintain good permeability ■ corrosion - polypropylene or polyester fiber as raw material, acid, non-corrosive, non-insect, anti-oxidation ■ simple construction - Weight light, easy to use, simple construction nonwoven action 1: isolate the use of polyester staple fiber needle geotextile for building materials have different physical properties (particle size distribution, consistency and density, etc.) (such as soil and sand, soil and concrete, etc.) in isolation. So between two or more materials is not lost, not mixed, maintaining the overall structure and function of materials, so that load bearing capacity of structures strengthened. 2: Filtration (filtration) When the water flows into the soil of coarse material from fine soil materials, the use of polyester staple fiber geotextile good air permeability and water permeability, water flow through, while effectively carrying soil particles, fine sand, small stones, so as to maintain a stable water and soil engineering. 3: Drainage polyester staple fiber geotextile has good water conductivity properties, it can formed inside the soil drainage channels within the structure of the soil efflux of excess liquids and gases. 4: use of reinforced polyester staple fiber needle geotextile reinforced soil tensile strength and resistance to deformation, enhance the stability of the building structure in order to improve soil quality. 5: protection of water when the soil to erosion, effective stress will focus on proliferation, transfer, or decomposition, to prevent soil damage by external force and which protect the soil. 6: puncture and combined into composite waterproof geomembrane impermeable material, play a role in anti-puncture. High tensile strength, good permeability, air permeability, high temperature, anti-freeze, anti-aging, corrosion, moth-eaten. Polyester staple fiber needle geotextile is a widely used geosynthetics. Reinforced widely used in railway embankment, road surface conservation, sports hall, dams protection, hydraulic construction of isolation, tunnel in a coastal beach, land reclamation and environmental protection projects.
