Woven Geotextile Fabric Vs Non Woven Geotextile Fabric

Woven Geotextile Fabric Vs Non Woven Geotextile Fabric

Woven Geotextile Fabric are made of high - strength fibrous materials. There are many kinds of materials, such as polyester, polypropylene, yarn and so on. This woven geotextile generally has strong tensile and compressive resistance. It does not drain well due to the specific weaving method. They are often used to provide reinforcement and separation. These characteristics make it a common material in the field of civil engineering. For example, highway, road construction, residential construction and so on.

Non woven geotextile fabric: Non woven geotextiles are made of long fibers . Compared with woven geotextiles, their strength is weaker. But their water permeability is strong. So they are often used in drainage and filtration fields. 

In the application field, the most common Non woven geotextile fabric is needled nonwoven geotextiles. Needled geotextiles are often used as crop coverings to warn of soil contamination. Another common nonwoven geofabric is spun-bonded nonwoven geofabric. The fiber is bonded by heating roller in its production method. So the spun clay geofabric is smoother than the needle-punched nonwoven geofabric. And the tensile strength of spun-bonded nonwoven geofabric is excellent.

The difference between woven and non woven geotextile fabric

There are many differences between Woven Geotextile Fabric and non woven geotextile fabric. And their characteristics are also different. So they are used in different fields. Let's take a look at the difference between machine woven fabric and non-woven fabric：

1. Woven geotextile is woven by machine. Non woven geotextile is bonded by mechanical, thermal bonding and other ways.

2. Woven fabric has a solid structure, which is used in heavy projects. It often used as materials for road construction and residential construction. But  non woven geotextile fabric relatively low strength.

3. Non woven geotextile fabric produced by spinbond, acupuncture and other processing techniques. So it has good permeability, high circulation rate. It often used in the field of filtration, drainage.

An explanation of the difference between woven and non woven geotextiles

• Manufacturing process: Woven geotextiles are woven on a loom. Non woven geotextiles are made by bonding polyester fibers through the process of spunbonding.
• Appearance: woven geotextiles feel rough, appearance like plastic. Non woven geotextiles feel soft, like plush appearance.
•  Water permeability: woven geotextiles are impermeable.
• Non woven geotextiles are impermeable and permeable.
•  Classification difference: Non woven geotextiles can be distinguished by weight.
•  Cost: Non woven geotextiles are more affordable than woven geotextiles, and the production speed is faster .
• Tensile property: Non woven geotextiles have better tensile property. The tensile rate is generally greater than 50%.

Application of woven geotextile fabric:

• Reinforcement: Woven geotextile fabric have strong and tough characteristics. It can be used to resist erosion, weed invasion, reinforcement steep slopes, etc.
• Stabilization: Woven geotextiles have stability and durability. It is suitable for keeping the soil stable.
• It also has the characteristics of resistance to ultraviolet erosion and long service life . So it is suitable for long-term application.

The use of Non Woven Geotextile Fabric:

• Separation: Non woven geotextile fabric is often used as a split cloth between two different materials. For example, it is often used as a barrier between two soils of different properties. It can separate and prevent mixing resulting in imbalance.
•  Filtration: Non woven geotextile fabric has better water permeability. It can separate water and other particles, is a better filtration material.
• Drainage: Non woven geotextiles can collect and transport some of the gas and liquid. Non woven geotextile fabric with better water permeability is suitable for drainage. For example,soil crop drainage, road sand area drainage.

French drain pipe

French drainpipes are one of the examples of non woven geotextile fabric applied to filtration scenarios. French drainage pipes are filled with gravel in drainage pipes. They are used to change the flow route of low standing water, thus solving the problem of low standing water. In this drainage system, non woven geotextile fabric are wrapped around the pipes. It can allow water to flow through while filtering soil and debris. And then prevent them from entering the pipes and forming blockages. So non woven geotextile fabric is also called landscape fabric or drainage fabric.
