Geotextile is a fabric used in the construction and infrastructure industry to reinforce and protect structures against the movement of soil and water. Geotextiles are usually made from plastic fibers such as polyester or polypropylene, which are resistant and waterproof.

The manufacturing process of geotextiles usually includes the following steps:

1. Material: The main raw material for the production of geotextiles is plastic fibers such as polyester or polypropylene. These fibers are made up of plastic particles through a process of hot pressing or stretching.
2. Yarn: The resulting plastic fibers are then spun into long fibers through processes such as thermal stretching or mechanical stretching. This improves the mechanical properties and strength of the fiber.
3. Synthesis: Plastic fibers are aggregated to form a geotextile woven roll. This process usually involves the use of machinery and weaving techniques to create the desired geotextile structure.
4. Treatment: Geotextiles can be further treated to improve water repellency, UV resistance, rot resistance, and other properties depending on the specific application.

Applications of geotextiles are diverse. Some popular applications include:

• Soil reinforcement: Geotextiles are used to cover weak soil areas and keep the soil from drifting or eroding. It is also used in the construction of earth retaining walls and dikes to provide stability and resist pressure from soil and water.
• Piling: Geotextiles can be wrapped around piles during foundation construction to provide local alignment and reinforcement.
• Runways and dikes: Geotextiles are used in the construction of airport runways and levees to reinforce soils and resist subsidence and cracking.

In summary, geotextile is not only a soil reinforcement and building protection material, but also has many important applications in the construction and infrastructure industries.
