Staple Fiber Needle Punched Geotextile
Staple fiber needle punched geotextile is made of polyester short fibers as raw materials, and is processed into a fabric shape through non-woven production equipment processes such as opening, combing, interlacing (short fibers interwoven with each other), laying (standardized entanglement and fixation), and needle punching.
Performance characteristics :
· High strength and deformation resistance: Short fiber needle punched non-woven geotextile forms a three-dimensional structure by interweaving, fusing, and fixing short fibers on a needle punching machine, which has high tensile and shear strength, can effectively disperse and transfer loads, and enhance soil stability.
· Breathability and permeability: Short fiber needle punched geotextile has good breathability and permeability, allowing water flow to pass through while intercepting sand loss, playing a filtering role.
· Hydraulic performance: It can form drainage channels inside the soil and discharge excess liquids and gases from the soil structure.
· Corrosion and oxidation resistance: Made from synthetic fibers such as polypropylene or polyester, it has the characteristics of acid and alkali resistance, non corrosion, non insect infestation, and oxidation resistance.
· Strain and mobility: The mesh structure formed by amorphous fibrous tissue exhibits strain and mobility, making the mesh less prone to clogging.

Main purpose
· Soil reinforcement: can be used to reinforce soil slopes, embankments, retaining walls, and other projects, improving the shear strength and erosion resistance of the soil.
· Soil separation: used to separate soil layers of different particle sizes, prevent soil particle mixing and infiltration, and maintain soil stability and drainage performance.
· Filtering and protection: In hydraulic engineering, it can serve as a filtering layer to prevent soil particles from passing through while allowing water flow to pass smoothly, effectively preventing the loss of fine particles and protecting downstream soil structures and drainage facilities. At the same time, it can also be covered on slopes or soil surfaces to prevent soil erosion caused by wind erosion, water erosion, and rainwater washing.
Application area
· Short fiber needle punched geotextile is widely used in civil engineering, water conservancy engineering, environmental engineering, transportation engineering and other fields due to its unique performance characteristics, playing a role in enhancing soil, protecting the environment and improving engineering quality.
Specifications and Selection
· The specifications of short fiber needle punched geotextile are diverse, with a width of up to 6 meters and a unit area mass ranging from 100 to 600 g/㎡. When choosing, appropriate specifications and types should be selected based on specific engineering requirements, soil conditions, environmental factors, and other comprehensive considerations.
· In summary, short fiber needle punched geotextile is a high-performance and widely used geotechnical material that plays an important role in modern engineering.
