Staple fiber needle-punched geotextile is a kind of non-woven fabrics usually used in industrial and construction area. The material can be polyproplene and polyester. The fibers are crimped staple with a fineness of 6-12 denier and a length of 54-64mm. It becomes to be cloth through the manufacturing process of opening, carding, messing (interwind short fibers together with each other), laying (standardized entanglement and fixing), and needle punching of non-woven production equipment.
Needle punch geotextile has the peculiarity of good air permeability, water permeability. So it can be used to make water flow through, as a result, it effectively stop intercepting sand loss. Because of good water conductivity, needle punch geotextile can let drainage channels fixed into the soil/sand, and discharge excess liquid and gas in the soil structure.
Under the help of geotextile, we can enhance the tensile strength and anti-deformation ability of the soil. We can improve the stability of the building structure and also improve the quality of the soil.
When needle punch geotextile used in construction area, it can help prevent the mixing between the upper and lower layers of sand, soil and concrete. As needle punch geotextile has the characteristics of high water permeability, even under the pressure of soil and water, it can still maintain very good water permeability.
Usually the material of needle punch geotextile is polypropylene and polyester, they are chemical fibers has the role in acid and alkali resistance, no corrosion, no moth-eaten, anti-oxidation. That is suitable to much industrial areas and it works.
In view of the wide application range of needle punch geotextile, they are very popular and hot seller both in domestic and foreign markets. So there’s no doult that it has also made a giant contribution to the progress of industry and the development of human beings.
