Geotextile is a permeable synthetic textile material made of polypropylene or polyester. In many civil, coastal, and environmental engineering structures, geotextiles have a long history of use in filtration, drainage, separation, and protection applications.When used in several different applications primarily related to soil, geotextiles have five key functions:1.) Separation;2.) Reinforcement;3.) Filtering;4.) Protection;5.) Drainage.
What is woven geotextile?
You may have guessed that woven geotextiles are made by mixing and weaving fibers together on a loom to form a uniform length. The result is that the product is not only sturdy and durable, very suitable for applications such as highway construction and parking lots, but also has excellent equipment to deal with ground stability issues. They are relatively impermeable and cannot provide the best separation effect. Woven geotextiles can resist UV degradation and are suitable for long-term use. Woven geotextiles are measured by their tensile strength and strain, with strain being the material’s flexural strength under tension.
What is non-woven geotextile?
Non woven geotextile is made by entangling long or short fibers together through needle punching or other methods. Then apply some additional heat treatment to further enhance the strength of the geotextile. Due to this manufacturing process and its infiltration Permeable, non-woven geotextiles are typically most suitable for applications such as drainage, separation, filtration, and protection. Non woven fabric refers to a weight (i.e. gsm/gram/square meter) that feels and looks more like felt.
Differences between Woven Geotextiles and Non woven Geotextiles
Material manufacturing
Non woven geotextiles are made by compressing fiber or polymer materials together at high temperatures. This manufacturing process does not require the use of yarn, but is formed through the melting and solidification of materials. In contrast, woven geotextiles are made by interweaving yarns together and weaving them into fabric.
Material characteristics
Non woven geotextiles are typically lighter, softer, and easier to bend and cut than woven geotextiles. Their strength and durability are also weaker, but non-woven geotextiles perform better in terms of waterproofing and moisture resistance. On the contrary, woven geotextiles are usually stronger and more durable, but they are not soft enough to bend and cut easily.
Application scenarios
Non woven geotextiles are widely used in waterproof and moisture-proof fields, such as water conservancy engineering, road and railway engineering, construction engineering, underground engineering, etc. Woven geotextiles are more suitable for fields that require greater pressure and weight, such as civil engineering, coastal protection, landfills, landscaping, etc.
Price difference
Due to differences in manufacturing processes and material properties, the prices of non-woven geotextiles and woven geotextiles also vary. Generally speaking, non-woven geotextiles are relatively inexpensive, while woven geotextiles are more expensive.
【 Conclusion 】
In summary, although non-woven geotextiles and woven geotextiles are important members of geotechnical materials, there are significant differences between them. Non woven geotextiles are more suitable for waterproof and moisture-proof fields, while woven geotextiles are more suitable for fields that require greater pressure and weight. The choice of geotextile depends on the specific application scenario and requirements.
Dongguan Liansheng Non woven Technology Co., Ltd. was established in May 2020. It is a large-scale non-woven fabric production enterprise integrating research and development, production, and sales. It can produce various colors of PP spunbond non-woven fabrics with a width of less than 3.2 meters from 9 grams to 300 grams.
