3. Characteristics of needle punched geotextiles
1) Needle punched geotextile has good air permeability and water permeability, it can allow water to pass through, so in terms of environmental protection, it can effectively intercept sand and soil loss.
2) The application of needle punched geotextiles can effectively enhance the tensile strength and deformation resistance of the soil, so that the building structure has better stability and the quality of the soil can also be improved.
3) The needle punched geotextile is laid on the ground, which can effectively prevent the mixing between the upper and lower layers of sand, gravel, soil and concrete, and at the same time prevent the coyotes from being damaged by external forces and protect the environment.
4) The needle punched geotextile has a mesh structure formed by an indefinite fiber structure, so it has good strain and fluidity, and is not easy to block when it is laid on the soil.
5) Needle punched geotextiles made of chemical fibers such as polypropylene or polyester have stable chemical properties and acid and alkali resistance.
9) Needle punched non-woven fabrics are light in weight and easy to use.
