Polypropylene staple fibers are made into cotton nets by carding machine, and then cross-layered. Or directly by the airflow netting machine into a cotton net with mixed arrangement of fibers, in order to achieve isotropic when forming cloth.
Then after a large number of felting needles consisting of a group or several groups of needle plate, needle felting fiber network. The fibers are made to entangle with each other and squeeze together to form a high quality polypropylene nonwoven fabric.
It has excellent water permeability, filtration, durability, creep resistance and corrosion resistance, etc. Short fiber geotextile fabric is usually not used alone. It is in the dyke slope, lining bottom that are covered under the block of stone or concrete precast slab. Thereby, a stable protective body is formed.

- Excellent isolation effect: Utilize good air permeability and water permeability of geotechnical cloth, so that the flow of water through, and effectively retain the sand and soil.
- Good water guide and drainage: The geotechnical cloth has good water conductivity, it can form a drainage channel in the soil, and discharge excess liquid and gas out of the soil structure.
- Best creep resistance: By using the geotextile to enhance the soil's tensile strength and anti deformation ability, enhance the stability of the building structure, play the role of reinforcement so as to improve the quality of the soil.
- Protect soil body: Effectively make the concentrated stress diffusion, transmit or decomposition, prevent the soil from being destroyed by external forces.
- Good isolation effect: Prevent the upper and lower layers of gravel, soil and concrete mixed.
- The mesh is not easy to be blocked: Due to unshaped fibrous tissue forms mesh structure has the characteristics of flexibility and Athletic performance.
- High permeability: Under the pressure of the soil and water, it still can maintain good water permeability.
- Corrosion resistance: Polypropylene or polyester fiber as raw material, acid and alkali resistance, no corrosion, no worm damage, antioxidant.
- Convenient construction: Lightweight, easy to use, construction is simple.
