Non woven filter fabric can be made of polyester or polypropylene. Needle-punched nonwovens made of polypropylene staple fibers are very popular in many countries. Nonwoven filter fabrics are used as separation fabrics when applications require higher water flow. This can include acting as a separator between the drainage gravel backfill behind the retaining wall, wrapping the stones around the pipe in the French drainage ditch, or acting as a cushion under the riprap. Nonwoven fabrics geotextile can also be treated to resist water flow, and combined with asphalt to form a waterproof barrier, which can be used as pavement cushion.
Needle Punched Geotextile Fabric Functions and Effects
The construction materials with different physical properties (particle size, distribution, consistency and density, etc.) were needle punched with polyester staple fiber geotextile. Materials (such as soil and sand, soil and concrete, etc.) are isolated. Make two or more materials do not run off, do not mix, keep the material. The overall structure and function of the material strengthen the loading capacity of the structure.
High tensile strength, good permeability, air permeability, high temperature resistance, freezing resistance, aging resistance, corrosion resistance, moth – free. Short fiber needle punched geotextile are widely used geosynthetics.
