Why Geotextiles Are Mostly Produced Using the Non-woven Needle-Punched Process?
In the Geosynthetic materials market, geotextile is a common material. The production process of geotextile is mainly divided into woven geotextile and nonwoven geotextile, and further divided into weaving, needle-punched, hot-melt bonding, etc. depending on the specific processing details. These geotextiles are suitable for different scenarios. However, if universality and versatility are taken as a reference,nonwoven needle-punched geotextile is a product that has been market-tested, with mature technology, affordable price and durability.
Q: Why is nonwoven needle-punched geotextile the most versatile geotextile product?
A: Because it achieves the best balance in terms of function, cost and adaptability.
1. Meet Core Functions
The main functions of geotextiles are filtration, drainage, isolation and protection. Geotextiles made by the needle-punched process can meet the core functions as follow.
- Three-dimensional fluffy structure: Under the needle-punched process, fibers are randomly arranged and form numerous pores. This gives it high vertical permeability and horizontal drainage capacity.
- Isotropic structure: Mechanical properties are basically consistent in all directions, able to evenly distribute stress from different directions, which very suitable for applications such as foundation reinforcement.
- High elongation and toughness: Able to adapt to uneven settlement and deformation of the foundation, not easy to tear, with good durability.
2. Stable production capacity with high benefits
- Wide adaptability of raw materials, especially for polyester (PET) or polypropylene (PP) short fibers.
- The production process is more refined and proven, with stable output and performance.
3. The application adaptability is extremely wide.
From roadbed drainage and landfill leachate management to filter layers and soil separation, needle-punched nonwoven geotextile is an effective solution for all these applications.
