Corrosion Resistant Nonwoven Geotextile For Environmental Engineering project
Product Introduction
Staple fiber geotextile is a kind of geomaterial with good water
permeability, which is widely used in civil engineering.
Product Advantages
1. Water permeability: water permeable short fiber geotextile has
good permeability and water permeability, can make water flow
through, while effectively intercepting soil particles, fine sand,
small stone, etc., to maintain the stability of soil and water
engineering.
2. Filterability: When water flows from the fine soil layer into
the coarse soil layer, the permeable staple fiber geotextile can
play a filtering role to prevent soil loss.
3. Durability: It has good tensile strength and deformation
resistance, which can enhance the stability of the building
structure.
4. Corrosion resistance: can resist the erosion of a variety of
chemical substances, suitable for different environmental
conditions.
Product Application
1. Water conservancy projects: In reservoirs, DAMS, canals and other projects, permeable staple fiber geotextiles are used for reinforcement and filtration.
2. Road construction: improve the bearing capacity and stability of
the roadbed, extend the service life of the road.
3. Environmental engineering: Prevent the spread of pollutants in
landfills, sewage treatment plants and other projects.
4. Slope engineering: Used for slope protection to prevent soil
erosion and landslides.

Production
1.Raw Material Preparation: The process begins with the preparation of raw materials, primarily polypropylene or polyester fibers. These fibers are cleaned and processed to ensure uniformity.
2.Fiber Opening and Blending: The fibers are opened and blended to create a homogeneous mixture. This step ensures consistent quality and performance of the final product.
3.Web Formation: The blended fibers are then fed into a carding machine, which aligns them into a thin web. This web is the foundational layer of the geomembrane.
4.Needle Punching: The fiber web is passed through a needle punching machine, where barbed needles interlock the fibers, creating a strong, non-woven fabric. This step enhances the mechanical strength and durability of the geomembrane.
5.Heat Calendering: The non-woven fabric is then subjected to heat and pressure in a calendering process. This step smooths the surface and improves the fabric's density and impermeability.
6.Coating or Lamination: Depending on the desired properties, the fabric may be coated or laminated with a polymeric material (such as polyethylene or PVC) to enhance its waterproofing capabilities.
7.Cooling and Cutting: After coating or lamination, the geomembrane is cooled and then cut into rolls or sheets of specified dimensions.
8.Quality Control: Each batch undergoes rigorous quality control tests to ensure it meets the required standards for strength, permeability, and durability.
9.Packaging and Shipping: Finally, the finished geomembrane rolls or sheets are packaged and prepared for shipping to various construction or environmental projects.
