The woven and non woven geotextile fabric are geotechnical materials used in civil engineering applications to improve the performance of soil and other materials. They can serve multiple functions such as filtration, drainage, separation, reinforcement, and erosion control. But there are frequently asked questions. Woven and non woven geotextile, what one is better? What is the Difference Between Woven and Non Woven Geotextile？How can we choose the right geotextile fabric for our specific projects?
BPM Geosynthetics is the leading geotextile manufacturer and supplier, we wholesale high quality geotextile fabric at competitive factory price. From the geotextile manufacturers’view, we will explore the key differences between woven and non woven geotextile fabric to help you select the right geotextile.
1 Introduction to Woven Geotextile and Non Woven Geotextile
1.1 What is Woven Geotextile?
Woven geotextile is a geosynthetic material woven from high-strength synthetic fibers. Woven geotextile is manufactured by interlacing individual yarns or fibers, typically made of polypropylene or polyester, in a woven pattern. The weaving process creates a strong and durable fabric with distinct openings or pores. Compared with non woven geotextiles, woven geotextiles have a distinct fabric structure and fiber intersections.
1.2 What is Non Woven Geotextile?
Non woven geotextile is a geosynthetic material that has a different structure and manufacturing method compared to traditional woven geotextiles. Non woven geotextiles are made of synthetic fibers or natural fibers through fiber interweaving, fiber bonding or melting methods to form a non-woven structure.
2 Overview of Woven Geotextile
2.1 Construction and Manufacturing Methods
Woven geotextiles are made by interweaving synthetic fibers, such as polyester or polypropylene fibers. This woven structure allows the geotextile to have obvious vertical and horizontal intersections, forming a strong fabric.
2.2 Functions and applications
Woven geotextiles have a variety of functions and applications in the fields of civil engineering, environmental engineering and construction, including:
Separation. Woven geotextiles can isolate and separate different soil layers, preventing soil mixing and sediment migration.
Filtration. Woven geotextiles filter particulate matter from water flow, preventing soil erosion and erosion while allowing moisture to pass through.
Reinforcement. Woven geotextiles can enhance the strength and stability of the soil and reduce soil deformation and subsidence.
Protection. Woven geotextiles can be used to protect earthwork structures, river banks, dams and other earthworks from the erosion of water flow, waves and erosion.
2.3 Characteristics and performance
Woven geotextile has the characteristics of high strength, durability and weather resistance. They usually have high tensile strength and puncture resistance, and can withstand large mechanical stress and environmental pressure.
2.4 Installation and construction
The installation method of woven geotextile usually involves laying it on the surface or in the soil and taking appropriate fixing measures, such as nails, clamps or ground nails. In some cases, woven geotextiles may need to be stitched or welded to form a continuous layer covering a larger area.
3 Overview of Non Woven Geotextile
3.1 Structure and manufacturing method
The fibers of BPM non woven geotextiles are interwoven, bonded or fused through mechanical or chemical methods. This manufacturing method makes the geotextile have a disordered arrangement of fibers and no obvious fabric structure, but forms a continuous fiber network.
3.2 Functions and applications
Non woven geotextiles have functions similar to woven geotextiles, including separation, filtration, reinforcement and protection. They are widely used in the fields of civil engineering, environmental engineering and construction for:
- Separation. Non-woven geotextiles can isolate and separate different soil layers, preventing soil layers from mixing and sediment migration.
- Filtration. non woven geotextiles filter particulate matter from water flow, preventing soil erosion and erosion while allowing moisture to pass through.
- Reinforcement. Non-woven geotextiles can enhance the strength and stability of soil and reduce soil deformation and subsidence.
- Protection. non woven geotextiles can be used to protect earthwork structures, river banks, dams and other earthworks against the erosion of water flow, waves and erosion.
3.3 Characteristics and performance
Non woven geotextiles have a variety of characteristics and performances, such as tensile strength, water permeability, chemical resistance and weather resistance. Depending on the specific engineering needs, suitable non woven geotextile types and specifications can be selected.
3.4 Installation and construction
The installation method of non woven geotextiles is similar to that of woven geotextiles, which usually involves laying it on the surface or in the soil and taking appropriate fixing measures, such as nails, clamps or ground nails.
