Woven geotextiles and non-woven geotextiles are two common types of geotextiles with different manufacturing processes and application areas.
Woven geotextiles and non-woven geotextiles are two common types of geotextiles with different manufacturing processes and application areas. The following are their main differences and applications:
Woven geotextiles
Differences:
1. Manufacturing process: Woven geotextiles are produced through a weaving process, using filaments or staple fibers to weave into fabrics.
2. Structural properties: Because they are woven, woven geotextiles usually have higher tensile strength and better shape stability.
3. Porosity: The pores are more uniform, but the porosity is relatively low.
Applications:
1. Reinforcement: Used to enhance the tensile strength and stability of soil, such as roadbed reinforcement for highways and railways.
2. Isolation: Used to isolate different materials to prevent mutual mixing, such as the isolation between gravel layers and soil layers.
3. Filtration and drainage: Used to prevent soil particles from being lost with water, such as filter materials in water conservancy projects.
Non-woven geotextile
Difference:
1. Manufacturing process: Non-woven geotextile is a fiber bonded together by mechanical, thermal bonding or chemical methods without traditional textile processes.
2. Structural characteristics: It has higher porosity and good permeability, but the tensile strength is generally lower than that of woven geotextile.
3. Flexibility: It is softer and easier to construct and lay.
Application:
1. Filtration: Due to its high porosity, it is suitable for use in filtration and drainage systems, such as the filter layer around the drain pipe.
2. Protection: It is used to protect structures such as anti-seepage membranes from mechanical damage.
3. Isolation: It is used to isolate materials of different particle sizes to prevent particle loss and mixing.
4. Reinforcement: It is suitable for projects with low strength requirements, such as reinforcement and support of small geotechnical projects.
