Woven geotextile and non woven geotextile belong to the same family, but we know that although brothers and sisters are born with the same father and mother, their gender and appearance are different, so there are differences between geotextile materials, but for customers who do not know much about geotextile products, the differences between woven geotextile and non woven geotextile are very vague.
Non woven geotextiles and woven geotextiles are two types of geotextiles that play important roles in engineering. However, for consumers who are not familiar with geotextile products, it is difficult to distinguish between the two. Below, we will make a detailed distinction between the production process, structure, and application fields of these two types of geotextiles.
Overall difference
Literally speaking, there is only one word difference between the two. So, what is the connection between woven geotextile and geotextile, and are they the same commodity? To be precise, woven geotextile belongs to a type of geotextile. Geotextile is a synthetic material that can be divided into woven geotextile, short fiber needle punched geotextile, and anti-seepage geotextile. Anti seepage geotextile is a woven geotextile that we often hear about. Woven geotextile is a type of geotextile anti-seepage material, which is composed of plastic film as the anti-seepage substrate and non-woven geotextile composite. Woven geotextile has better isolation and impermeability than ordinary geotextile. You can also understand this difference literally. One is film, and the other is fabric. The roughness of the fabric and the small gaps during weaving shall not be lower than that of the impermeable film. Of course, we cannot fully understand this. Woven geotextile is a composite of plastic film and non-woven fabric, which combines the excellent characteristics of two materials and forms new advantages due to the complementarity of the two materials.
Production process
Non woven geotextile is made by integrating polymer chemical fiber materials (such as polyester, polyamide, polypropylene, etc.) into a mesh and bonding them using processes such as melt spraying, heat sealing, chemical bonding, and mechanical bonding. In this process, there is no obvious mesh structure on the surface of non-woven geotextile, which looks similar to ordinary fabrics. The production process is relatively simple and the cost is low.
Woven geotextile is made by threading, weaving, and compacting wire through a weaving machine. During the production process, different specifications of woven geotextiles were obtained through special weaving rules and testing of fracture strength, tear strength, and other aspects. This process has a long history and mature technology, and can produce fabrics of various specifications and textures.
Structure and performance
The fiber structure of woven geotextile is tight and orderly, with high tensile strength and wear resistance, and can withstand significant external forces, making it very suitable for use in harsh environments. The fiber structure of non-woven geotextiles is relatively loose, but their permeability, filtration, and flexibility are better, making them widely used in fields such as water conservancy and environmental protection.
Application area
Non woven geotextiles are mainly used in geotechnical engineering for drainage, waterproofing, and sun shading purposes. Common applications include slope protection engineering, road reinforcement, water barriers, and so on. Due to its excellent water and odor resistance, it can also be used for waterproofing of building roofs and gardens, drainage of lawns, as well as dust prevention and maintenance of home furniture.
Woven geotextile is mainly used as one of the geotechnical materials and is widely applied in fields such as engineering, water conservancy, and soil treatment. In engineering, it is mainly used for anti-seepage and soil stabilization, slope reinforcement, etc; In terms of water conservancy, it is mainly used for dam surfaces, hydraulic structures, river composites, artificial lakes and ponds, reservoir seepage prevention, and other aspects. In terms of soil remediation, it is mainly used for desertification, soil erosion, etc.
Conclusion
Overall, woven geotextiles and non-woven geotextiles each have their unique advantages and applicable scenarios. Woven geotextiles are suitable for applications that require high strength and durability, while non-woven geotextiles are suitable for engineering projects that require good permeability and flexibility.
