Non-woven geotextile fabric is becoming an indispensable material in modern civil engineering and construction. It plays an important role in various engineering projects due to its excellent functionality and wide range of applications.
Non-woven geotextile fabric is an engineering material made of synthetic fibers interwoven by mechanical, thermal or chemical methods. Unlike traditional woven or knitted fabrics, this fabric does not have a clear weaving structure between its fibers, but instead uses different techniques to fix the fibers together to form a fabric with high strength and good stability. Common raw materials include synthetic fibers such as polyester (PET) and polypropylene (PP).
High strength and durability: Non-woven geotextiles have excellent tensile strength and abrasion resistance, which makes them perform well when subjected to geological pressure and external impact.
Excellent water permeability: Compared with traditional fabrics, non-woven geotextiles are more permeable, which helps prevent soil erosion and maintain soil stability.
Good filtering performance: Its fiber structure can effectively filter fine particles and prevent soil particles from being lost while allowing water to pass smoothly.
Environmentally friendly: Due to the corrosion resistance of its materials, nonwoven geotextiles can maintain stability under a variety of environmental conditions and reduce negative impacts on the environment.
Road and railway construction: In the construction of roads and railways, nonwoven geotextiles are widely used to reinforce the base bed, reduce settlement, and improve the bearing capacity of roads.
Soil stability: In projects such as embankments and river bank protection, nonwoven geotextiles can effectively prevent soil erosion and loss and enhance soil stability.
Landfill: In landfills, nonwoven geotextiles are used on the bottom and sides to help isolate garbage from the surrounding environment and prevent leachate from contaminating soil and water sources.
Construction projects: In building foundation projects, nonwoven geotextiles are used to prevent water loss in concrete and improve the stability and durability of the foundation.
The use of nonwoven geotextiles has brought significant engineering benefits. First, it can effectively reduce project costs because its low maintenance requirements and long service life reduce the overall project maintenance costs. Secondly, its application improves the safety and stability of the project and reduces the potential risks caused by soil instability or soil erosion. In addition, its excellent filtration and water permeability enable it to maintain good functional performance under complex environmental conditions.
