Geosynthetics-synthetic Staple Fibers Needlepunched Nonwoven Geotextile

The core advantage of needle punched non-woven geotextile is the formation of a three-dimensional structure through fiber entanglement, which combines high strength and excellent permeability, adapts to the needs of geotechnical engineering in multiple scenarios, and has a simple production process and controllable cost. Its specific advantages can be divided into the following 5 points: -Strong performance adaptability: It has sufficient tensile and bursting strength (able to withstand soil pressure and external impact), as well as excellent filtration and drainage properties (allowing water flow to pass smoothly while intercepting soil particles to avoid loss). -Good environmental tolerance: acid and alkali resistance, corrosion resistance, aging resistance, long-term stability in soil, water conservancy and other complex environments, and long service life. -Convenient and efficient construction: With soft texture and light weight, it can be cut and spliced according to project requirements. When laying, it fits the terrain of the site without the need for complex construction equipment, which can greatly save construction time. -Outstanding cost-effectiveness: The production process is relatively simple, and the raw materials (polyester, polyester short fibers) are easily available. On the premise of meeting the core requirements of the project, the cost is lower than that of some composite geotechnical materials. -Full functional diversity: It can simultaneously achieve the five core functions of isolation, reinforcement, protection, filtration, and drainage, without the need for multiple materials, simplifying the engineering design and material procurement process.
