The main application of geotextile and the difference between short silk cloth and long silk cloth

Geotextile is a category of non-woven fabrics. There are filaments and short filaments, and their uses are quite different. The simplest way to distinguish between filament and short filament is to distinguish by appearance. The surface fiber of the national standard short filament geotextile is shorter, and the product color is slightly darker than the filament geotextile. The surface fiber of the national standard filament geotextile product is longer and the product color is whiter. Next, let's look at the main applications of geotextiles and the difference between short silk cloth and long silk cloth. Detailed differences: 1. The possibility of clogging of polyester filament geotextiles is less. The porosity of polyester filament geotextiles is larger and the porosity of polyester staple fiber geotextiles is smaller. The filament geotextile is different from the polyester staple fiber geotextile in terms of fiber form and production process. 2. The creep resistance of polyester filament geotextile of the same unit area quality is better than polyester staple fiber geotextile, and the puncture resistance of filament geotextile is better than polyester staple fiber geotextile. 3. Filament geotextile production equipment has a large investment and high technical content, and is generally produced by large factories, while the short fiber geotextile equipment is relatively simple and the product quality varies. 4. The anti-ultraviolet ability of geotextile itself is related to its thickness, and the effect of ultraviolet rays on polyester filament geotextile is mainly reflected in the surface layer. The friction coefficient of filament geotextile is obviously greater than that of polyester staple fiber geotextile, which can protect the geomembrane from ultraviolet aging. Main application: Filament geotextile has good vertical and horizontal drainage performance, good extension performance and high chemical stability such as biological resistance, acid and alkali resistance, and aging resistance. It also has good mechanical properties. It is a geosynthetic material used in geotechnical engineering and civil engineering. It is made by the method of forming and consolidating polyester filaments, and its fibers are arranged in a three-dimensional structure. On the sandy rivers, the banks that do not lean on the sluice are immediately blocked by sediment, and it is unlikely that there will be a swirling flow, and the shoreline also stopped collapsing because of the protection of the new beach. Sometimes through a series of chain actions, the river bank has a zigzag ten shape, which can be seen on both the Lower Jingjiang River and the South Canal. After the filament geotextile makes it strong, it greatly reduces c. The bank collapses makes the shoreline at the place four in, and its downstream shoreline appears to be more protruding, which has a picking effect on agricultural currents. A swirling area may appear at the protruding point T Cause the shoreline to collapse. The latter has a greater impact on the hard and weak soil with cracks. The water movement in the soil can cause leaching and maceration. The former has a great impact on the loess, because when the educational field grains are taken away, it will make the loess The strength loss is exhausted. In rivers in icy areas in winter, the expansion of ice will weaken the connection and cohesion between soil particles. The ice pressure in the river or the impact of flowing ice on the river bank will also cause the river bank to collapse or loosen the soil. The continuous changes in soil mass will cause it to shrink and expand repeatedly, causing cracks and forming soil blocks of varying sizes. On some rivers, the size reaches o. Level 5: When the bank collapses, the whole piece of soil collapses. When the soil has a large water content, the pore water pressure can reduce the strength of the soil. Rainfall, snowmelt, or high river water levels can cause the increase in soil moisture. It acts directly in the soil to weaken its strength and acts on the surface of the bank to loosen soil particles. The above is the detailed content of the main application of geotextile and the difference between short silk cloth and long silk cloth.
