Staple Fiber Geotextile Resistant to Corrosion and Chemicals for Long Service Life
Product Introduction
Short fiber geotechnical fabric is an important type of geosynthetic material, mainly made from synthetic fibers such as polyester through production processes like loosening, combing, tangling (short fibers intertwined), and web laying (standardized knotting and fixation) on non-woven production equipment to form a fabric. This material exhibits excellent properties including acid and alkali resistance, corrosion resistance, aging resistance, high strength, dimensional stability, and good filtration characteristics.
Product Properties
1. Water permeability: Staple fiber geotextile has high water permeability, even under the pressure of earthwork, it can maintain good water permeability. This characteristic allows it to effectively control the water table and prevent the accumulation of water, thus improving the stability of the foundation.
2. Corrosion resistance: The staple fiber geotextile is made of acid and alkali resistant chemical fiber materials, which will not be corroded by acid and alkali substances, nor will it be eaten or oxidized, which makes it have a long service life.
3. Simple construction: short fiber geotextile light weight, easy to use, easy to construction. It can be tailored and used according to specific needs, reducing the difficulty and cost of construction.
4. Tensile strength: Although the fracture strength and other parameters of staple fiber geotextile may not be as high as that of filament geotextile, it still has a certain tearing resistance and tensile strength. This makes it show good adaptability when dealing with surfaces with complex terrain or large curvature.
Product Application
The application field of short fiber geotechnical fabric is very extensive, including but not limited to the following types of engineering:
Water Conservancy: Used for functions such as imperviousness, drainage, and isolation.
Road and Rail: Used for road reinforcement, drainage, and isolation.
Dams and Reclamation: Used to prevent seepage and protect the soil.
Airport Construction: Used for ground reinforcement and drainage.
To sum up, short fiber geotechnical fabric, with its excellent performance and wide range of applications, plays an indispensable role in modern civil engineering.
