As an engineering material widely used in water conservancy, highway, railway, construction, environmental protection and other fields, the stability and durability of woven geotextile performance are crucial. Especially when exposed to outdoor environment for a long time, how to effectively resist UV radiation, chemical corrosion and biodegradation has become an important criterion for measuring the quality of woven geotextile.Woven geotextile usually uses high-strength polyester fiber or other synthetic fiber as the main raw material, which itself has good UV resistance. In addition, in order to further improve its UV resistance, anti-UV additives can be added during the production process. These additives can absorb or reflect UV rays, thereby reducing the direct damage of UV rays to geotextiles. At the same time, dark geotextiles are relatively more resistant to UV rays. Therefore, in outdoor applications, choosing dark geotextiles is also an effective protection strategy.Chemical corrosion is another major challenge facing woven geotextiles. In soil, water or air, there may be various chemicals, such as acids, alkalis, salts, etc., which may corrode geotextiles. In order to resist chemical corrosion, woven geotextiles are specially treated during the production process to enhance their chemical stability. For example, corrosion-resistant fiber materials are used, or the fiber surface is modified to improve its chemical corrosion resistance.Biodegradation is another problem that woven geotextiles need to face in outdoor environments. Some microorganisms or enzymes may decompose the fibers in geotextiles, resulting in a decrease in their performance. In order to resist biodegradation, geotextile manufacturers will choose fiber materials with anti-biodegradation properties, such as polyester fibers. At the same time, the anti-biodegradation properties of geotextiles can be further improved by adding anti-biodegradation additives.In addition to material selection and treatment processes, the design and installation methods of woven geotextiles also have an important impact on their ability to resist outdoor environmental challenges. For example, a reasonable laying method can reduce the exposure area of geotextiles in outdoor environments, thereby reducing their risk of ultraviolet radiation, chemical corrosion and biodegradation. In addition, regular inspection and maintenance are also key to ensuring the long-term performance and stability of geotextiles.In summary, woven geotextile effectively resists challenges such as ultraviolet radiation, chemical corrosion and biodegradation in outdoor environments by selecting high-performance fiber materials, adding anti-ultraviolet, anti-chemical corrosion and anti-biodegradation additives, and reasonable design and installation methods, providing strong guarantees for the safety and stability of various engineering projects.
