High Reinforcement Polyester Nonwoven Geotextiles Soil Filter Fabrics Permeate And Road Construction
Description:
Polyester non-woven geotextile is a non-woven geosynthetic material made of polyester (PET) staple fiber through a needle punching process. It has the characteristics of high strength, strong permeability and corrosion resistance.
Basic characteristics
1. Materials and processes
· Raw materials: polyester curly staple fibers, which are formed into a stable cloth-like structure through opening, carding, web laying and needle punching processes.
· Features: high tensile strength, good water permeability, high temperature resistance (-30℃~120℃), anti-aging, acid and alkali corrosion resistance, and insect resistance.
2. Physical parameters
· Width: 1-6 meters, roll length 50-100 meters, unit area mass 100-800 grams/square meter, thickness is related to gram weight (such as 400g thickness is about 3.0mm).
Key functions
1. Isolation and protection
· Separate different soils or building materials to prevent mixing and enhance structural stability (such as railway roadbed isolation).
· Prevent soil erosion and reduce the scouring damage of water flow to the soil body, suitable for river channel and dam protection.
2. Filtration and drainage
· Allow water flow to pass while intercepting soil particles to maintain project stability (such as drainage system filter layer).
· Form drainage channels to discharge excess liquid and gas in the soil and improve soil quality.
3. Reinforcement and reinforcement
· Enhance the tensile strength and deformation resistance of the foundation, and improve the bearing capacity and seismic resistance of roads, tunnels and other projects.

Project Applications
1. Agriculture and gardening
·Prevent soil erosion and reduce weed growth (such as rice fields and orchard weed control cloth).
·Slope greening and artificial lake anti-seepage (such as garden landscape engineering).
2. Water conservancy and environmental engineering
·Dam and landfill anti-seepage, river slope protection and ecological restoration.
·Sewage treatment and groundwater pollution prevention.
3. Transportation infrastructure
·Highway/railway subgrade reinforcement, airport runway base isolation, tunnel drainage layer.
Construction precautions
1. Key points for laying
·Clean up debris from the ground to ensure that the base is flat; overlap width ≥ 20cm, and the seams are fixed by hot melt or stitching.
·Cover with a protective layer (such as soil or gravel) to prevent aging caused by direct ultraviolet radiation.
2. Maintenance and inspection
·Regularly check for damage or deformation, and repair or replace in time.
