Geotextile, also known as geotextile fabric, is a permeable geosynthetic material made from synthetic fibers through needling or weaving. It is one of the new materials in the category of geosynthetic materials, coming in a fabric form, typically with a width of 4-6 meters and a length of 50-100 meters.
Product Categories
One, needle-punched nonwoven geotextile
Manufactured from raw materials of short fibers, this product undergoes a process using nonwoven production equipment, including opening, carding, tangling (interweaving of short fibers), webbing (standardized entanglement and fixation), and needle punching to create a fabric-like finish. Features: The product boasts properties such as resistance to acids and alkalis, corrosion resistance, aging resistance, high strength, stable dimensions, and good filtration. Applications: Primarily used for reinforcing, isolating, anti-filtering, and drainage in engineering projects, widely utilized in water conservancy, highway, and railway fields.
Short Fiber Geotextile Test Criteria
Polyester Long Fiber Geotextile
Polyester staple geotextile is directly manufactured by spinning, needle-punching, and consolidation using the polyester method. The product specifications range from 80-800g/㎡ for any selection. It is a type of geosynthetic material used in geotechnical and civil engineering, made by weaving polyester staple fibers into a mesh and consolidating them. The fibers are arranged in a three-dimensional structure. In addition to its excellent mechanical properties, it also boasts good longitudinal and transverse drainage capabilities, excellent elongation properties, and high chemical stability against biological degradation, acidity, alkalinity, and aging.
Polyester Filament Geotextile Test Indicators
Polyester Filament singed geotextile
This product features a sintered layer on the base of polyester staple fiber felt geotextile, achieving the goal of no clumping on the non-woven geotextile surface while maintaining its original properties. It is designed and developed in accordance with the current "Technical Specification for Sanitary Landfill of Domestic Waste" CJJ17-2004 standard, specifically for anti-slip design of the slope of waste sanitary landfill sites. It effectively prevents damage to synthetic fibers from ultraviolet rays, enhancing the geotextile's resistance to aging; the textured single (or double) side of the geotextile also provides excellent application performance.
It features the following characteristics:
(1) Widely used for reinforcing asphalt pavements, cement concrete pavements, and subgrades. Suitable for both rigid and flexible pavements, it can reduce construction costs compared to traditional pavements, extend service life, and prevent road reflective cracking.
(2) The product has an appropriate thickness, easily bonding with asphalt pavements. When combined with adhesive oil, it forms an isolation layer that provides waterproofing and thermal insulation properties.
(3) Lightweight with high strength. Tensile strength is all ≥ 8 KN/m, elongation is 40% to 60%, fully meeting the technical requirements for geotextiles in JTJ/T019—98 "Technical Specification for Road Geosynthetic Stress."
(4) Surface is rough and not slippery. During installation, place the rough side up after a special treatment to increase friction and bond the surface layer, preventing it from being picked up or damaged by wheels during construction. This also helps to suppress the slipping of vehicles and pavers on the surface.
(5) Features UV protection, frost resistance, chemical corrosion resistance, and biological degradation resistance.
(6) Easy to install with excellent application results. Generally, the fibers of geotextile are easily picked up by vehicle tires, causing fraying, and in severe cases, they can be wrapped around, leading to displacement and structural damage of the geotextile.
Four: Nonwoven Geotextile
Non-woven geotextile (polyester geotextile, non-woven geotextile) is also known as geotextile. It is a permeable geosynthetic material made by needle-punching or weaving synthetic fibers. The finished product is in fabric form, primarily composed of polyester short fibers, with widths generally ranging from 4 to 6 meters and lengths from 50 to 100 meters. It is widely used in projects such as railways, highways, sports venues, embankments, hydraulic structures, tunnels, coastal roads, reclamation, and environmental protection.
Five, Polypropylene Geotextile
Polypropylene geotextile features excellent permeability, filtration, durability, and is widely used in projects such as railways, highways, sports centers, dams, hydraulic structures, tunnels, coastal beaches, reclamation, and environmental protection. Mainly includes short fiber needle-punched nonwoven polypropylene geotextile and split film woven polypropylene geotextile.
Polypropylene Geotextile Function:
Utilizing the excellent breathability and permeability of polypropylene geotextile, it allows water flow while effectively retaining soil erosion.
Effectively dissipate, transfer, or decompose concentrated stresses to prevent soil from being damaged by external forces.
Prevent mixing between the sand, stone, soil, and concrete layers above and below.
The mesh is less prone to clogging due to the strain and mobility of the mesh structure formed by the amorphous fiber organization.
High permeability, maintaining excellent permeability even under the pressure of soil and water.
Corrosion-resistant, made from synthetic fibers like polypropylene or polyester, acid and alkali-resistant, non-corrosive, termite-proof, and anti-oxidation.
Easy to install, lightweight, and user-friendly.
