What is Non-woven Geotextile Fabric?
Non-woven geotextile fabric is a type of permeable textile material made from synthetic fibers, which are bonded together by mechanical, thermal, or chemical means, rather than being woven. It is used in a wide range of civil engineering and construction applications, including road and railway construction, drainage systems, erosion control, and soil stabilization.
The primary function of non-woven geotextile fabric is to separate, filter, reinforce, or protect the soil or other construction materials. It acts as a barrier to prevent the mixing of different soil layers or materials, while allowing water to pass through freely. It can also prevent the loss of soil particles and reduce soil erosion, while providing additional strength and stability to the underlying structure.
Non-woven geotextile fabric is available in various thicknesses, strengths, and sizes, depending on the specific application. It can be made from a variety of synthetic fibers, including polypropylene, polyester, and polyethylene. The fabric is typically manufactured using a process known as needle punching, which involves punching thousands of tiny needles through the fibers to interlock them and create a durable, stable fabric.
How to maintain Non-woven Geotextile Fabric?
Non-woven geotextile fabric is commonly used in civil engineering and construction projects to provide filtration, separation, and drainage functions. To maintain the effectiveness and durability of the fabric, it is important to follow these guidelines:Keep the fabric clean: Dirt, debris, and other contaminants can clog the pores of the fabric and reduce its filtration and drainage capacity. Regularly remove any accumulated debris by sweeping or blowing the surface of the fabric with a high-pressure air blower.
Inspect for damage:
Non-woven geotextile fabric is susceptible to damage from sharp objects, heavy equipment, and other sources. Regularly inspect the fabric for tears, punctures, or other damage that could compromise its effectiveness. Repair any damage promptly to prevent further deterioration.Avoid overexposure to UV light: Non-woven geotextile fabric is not resistant to UV light, and prolonged exposure can cause it to degrade and lose its effectiveness. Avoid exposing the fabric to direct sunlight for extended periods of time, or use a UV-resistant coating or cover to protect it.
Store properly: When not in use, store the fabric in a dry, cool, and dark location to prevent moisture buildup, mold growth, or exposure to UV light. Avoid folding or creasing the fabric, as this can cause permanent damage to its structure.By following these maintenance guidelines, you can ensure that your non-woven geotextile fabric remains effective and durable for its intended use in civil engineering and construction projects.
