Short-fiber needle-punched geotextile is a relatively common geotextile fabric for drainage engineering material, which can fully adapt to the needs of different engineering buildings. Today, geogridfactory to bring a detailed introduction of staple fiber needle-punched geotextiles, so that everyone can better understand engineering materials such as staple fiber needle-punched geotextiles. Let’s take a look together. !
What is staple fiber needle-punched geotextile?
Staple-fiber needle-punched geotextiles use filaments or short fibers as raw materials, which are laid out in a mesh form through different equipment and construction techniques, and then different fibers are intertwined and fixed with each other through acupuncture and other techniques to standardize the fabric. The second is to make the fabric itself soft, plump, and heavy, and to realize fabrics of different thicknesses, so that the product itself can meet the specified requirements.
Advantages and disadvantages of staple fiber needle-punched geotextiles
- Short-fiber needle-punched geotextiles have many advantages, such as: ventilation performance, water filtration, frost resistance, water resistance, good hand feeling, softness, tear resistance, elasticity, etc., and can return to the previous non-directional fabric Compared with textile fabrics, the performance is higher, the production speed will be faster, and the price will be cheaper, etc.;
- Defects of short-fiber needle-punched geotextiles: Compared with textile fabrics, the strength and durability are relatively poor, and they cannot be cleaned like other fabrics; the fibers must be arranged in the specified direction, so they are easy to crack at right angles. The first plant fibers used in industrial staple fiber geotextiles are cotton and jute, and the main chemical component is cellulose;
- Cotton and jute are used to make labor insurance clothing, packaging and military cloth, etc., which are all short-fiber geotextiles for industrial use in the early stage, which simply means that the grade is very low. With the continuous growth of the national economy, the proportion of plant fibers in industrial fibers will gradually decrease, and composite fibers will replace them.
Characteristics and uses of staple fiber geotextiles
As one of the most commonly used engineering materials, staple fiber needle-punched geotextiles can meet the needs of various engineering constructions. For example, the application of short-fiber needle-punched geotextiles to highways and road maintenance projects can enhance the anti-seepage ability of roadbed projects and improve the drainage performance of road surfaces. If this material is applied to engineering buildings, it can achieve the effects of anti-seepage, water filtration, isolation, sealing, reinforcement and protection. In short, the material quality of single staple fiber needle-punched geotextile is very important in the project;
The tensile properties are a crucial feature for staple fiber needle-punched geotextiles. Only with better tensile properties can the service life of geotextiles be extended, and at the same time avoid being damaged by the outside world, thus It promotes the effectiveness of geotextile materials in engineering construction. Geotextile synthetic materials have been widely used in my country at this stage, and they have also involved many industries. However, due to the variety of detection reasons, there are often deviations in the test structure of geotextile synthetic materials, which ultimately affects the credibility of the test results;
Short-fiber needle-punched geotextiles can be fully used in road maintenance, highway construction, tunnel construction and other fields, so they have a wide range of application advantages, and there will be differences in the performance of short-fiber needle-punched geotextiles with different specifications. Make reasonable choices according to actual needs.
