■ Short-fiber non-woven geotextile is made of polyester or polypropylene short fiber, which is processed by combing and laying nets, reinforcing by repeated needling, and proper hot rolling, shaping, surface treatment, etc. Non-woven fabrics have no warp and weft lines, the fabric fibers are messy, and the difference between warp and weft properties is small.
Product performance:
■ Short-fiber non-woven geotextile, with excellent water permeability, filter, high strength, wear resistance, anti-aging and other characteristics, can effectively prevent soil erosion and loss, maintain soil stability; The main functions are reinforcement, isolation, drainage, reverse filtration and so on.
■ Product application field:
It can be widely used in water conservancy, highway, railway, airport, port, municipal, environmental protection, tunnel, urban landfill and other engineering construction fields.
