产品介绍：
Geotextile, also known as geotextile fabric, is a permeable geosynthetic material made of synthetic fibers through needling
or weaving. Geotextile is one of the new types of geosynthetic materials. The finished product is in the form of a fabric, with
a general width of 4 to 6 meters and a length of 50 to 100 meters. Geotextiles are classified into woven geotextiles and non-
woven filament geotextiles.
Features
1. High, due to the use of plastic fibers, it can maintain sufficient elongation in both dry and wet conditions.
2. Corrosion-resistant, it can resist corrosion for a long time in soil and water with different levels of acidity and alkalinity.
3. Good water permeability: There are gaps between the fibers, so it has excellent water seepage performance.
4. Good antimicrobial properties: It is not damaged by microorganisms or insect infestation.
5. Convenient for construction: Due to its light and flexible material, it is easy to transport, lay and install.
6. Multiple specifications: The width can reach up to 9 meters. Mass per unit area: 100-1000g/m ²
Function
Filtration (reverse filtration
When water flows from fine-grained soil layers into coarse-grained soil layers, the excellent air permeability and water
permeability of polyester short-fiber needled geotextile allow water to pass through while effectively intercepting soil
particles, fine sand, small stones, etc., to maintain the stability of water and soil engineering.
Drainage
Polyester staple needled geotextile has excellent water-conducting performance. It can form drainage channels within
the soil mass, allowing the excess liquid and gas in the soil structure to be discharged outward.
Reinforcement
Polyester staple needle-punched geotextile is utilized to enhance the tensile strength and anti-deformation capacity of
soil, improve the stability of building structures, and thereby improve the quality of soil.
Protection
When water flow erodes the soil, it effectively diffuses, transmits or decomposes the concentrated stress, preventing the
soil from being damaged by external forces and thus protecting the soil.
Puncture-resistant
When combined with geomembrane, it becomes a composite waterproof and anti-seepage material, which plays a role
in preventing puncture. High tensile strength, good permeability, good air permeability, high temperature resistance,
frost resistance, aging resistance, corrosion resistance, and no insect damage. Polyester staple needled geotextile is a
widely used geosynthetic material. It is widely used in railway subgrade reinforcement, highway pavement maintenance,
sports venues, embankment protection, isolation of hydraulic structures, tunnels, coastal tidal flats, reclamation, environ-
mental protection and other projects.
