Woven Geotextile VS. Non Woven Geotextile
Woven geotextiles and nonwoven geotextiles are two types of geotextiles that are used for different purposes in various civil engineering and construction applications. There is often still some confusion as to which product to use on your Jobsite. Common misconceptions about the functions of a woven geotextile vs. a nonwoven geotextile can often lead to added confusion. We will go into detail about the differnece between woven and non woven geotextiles and their functions.
Woven Geotextiles
The first generation of woven geotextiles was made from cut strips. Slitting tapes are extruded flat yarns woven at a 90-degree angle to create durable textiles. Due to their broad, smooth surfaces, they have very poor water permittivity and low soil interaction properties. These factors make them poor choices for residential applications, especially in wet conditions.
Over time, the development of high-performance woven geotextiles has led to a more efficient material. Woven geotextiles are made from long, continuous strands of synthetic fibers that are interwoven to form a strong, durable fabric. These developments have increased flow rates and higher interaction coefficients, making them more suitable for civil applications by providing separation, confinement and reinforcement. They are often used for soil stabilization and erosion control, as well as for reinforcement in retaining walls, roads, and other structures. Woven geotextiles have high tensile strength and can withstand high levels of stress. They also improve filtration and drainage.
Non woven Geotextiles
Nonwoven geotextiles, on the other hand, are made from short fibers that are randomly arranged and bonded together using heat, chemicals, or mechanical processes. Nonwoven geotextiles are more flexible and conformable than woven geotextiles, making them well-suited for applications where flexibility and conformability are important. They are often used for filtration, separation, and drainage in civil engineering and construction projects. Nonwoven geotextiles have lower tensile strength than woven geotextiles, but they are still strong enough for many applications.
When it comes to the manufacturing of a nonwoven geotextile, there are many different methods used today. The most common manufacturing method is by needle-punching. Needle-punched nonwoven geotextiles are made by taking a large number of small fiber fibers and using a barbed needle to interlock the fibers together. Nonwoven geotextiles are generally used to provide separation, combined with filtration and drainage functions when used in a civil application.
Non Woven Geotextile applies to foundations of public construction projects (railways, roads, reservoirs, tunnels) and buildings under permanent drainage systems, separation, stabilization and support. Specifications provided by public and private institutions to apply to public construction projects.
In summary, the main differences between woven and nonwoven geotextiles are their manufacturing processes, physical properties, and intended applications. Woven geotextiles are made from continuous fibers that are interwoven to form a fabric, while nonwoven geotextiles are made from short fibers that are bonded together. Woven geotextiles have higher tensile strength and are used for soil stabilization and reinforcement, while nonwoven geotextiles are more flexible and are used for filtration, separation, and drainage. click here
