5 Benefits of Non-woven PET Geotextile Layer

The non-woven PET filament geotextile layer offers several benefits in geotechnical applications. Let’s explore them in more detail:

1. Excellent Hydraulic Performance: The thickness of the non-woven PET filament geotextile layer ensures a three-dimensional void ratio, which contributes to the establishment of excellent hydraulic performance indicators. This means that water can pass through the geotextile layer efficiently, allowing for proper drainage and preventing water buildup.

2. High Bursting Strength: The bursting strength of the non-woven PET filament geotextile layer is a significant advantage, particularly in applications such as retaining walls and roadbed reinforcement. The geotextile layer can withstand high pressure and stress, providing structural stability and preventing failure or collapse.

3. Superior Tensile Strength: The tensile index values of the non-woven PET filament geotextile layer surpass industry standards. This indicates that the geotextile layer has excellent tensile strength, making it a reliable material for geotechnical reinforcement. It can withstand heavy loads, distribute stresses, and enhance the overall strength and stability of the construction.

4. Standardized Production Process: The production process of non-woven PET filament geotextiles has been standardized, ensuring consistent quality and performance. This standardization allows for reliable and predictable results in road construction and other geotechnical applications.

5. Demonstrated Competitiveness: Non-woven PET filament geotextiles of various specifications have been widely adopted in the construction of asphalt highways and asphalt pavement repairs. Their technical and economic efficiency has been demonstrated, showcasing their competitiveness as a geotechnical reinforcement solution.

6 Laying Method of Non Woven Pet Geotextile Layer

  1. Use manual rolling; the surface of the fabric should be leveled, and a moderate allowance for deformation processing should be left.
  2. The laying of long-filament or short-filament geotextiles generally adopts lap joints, stitching and welding. The width of stitching and welding is generally more than 0.1m, and the lap width is generally more than 0.2m. Geotextiles that may be exposed for a long time should be welded or stitched.

From the above overall view, the application of filament geotextiles in high speed has been well promoted, which in turn provides a good guarantee for saving project costs and improving the service life of the project. ​

7 Summary

Non-woven PET filament geotextile layer has played an important role in providing working solutions for the construction or improvement of secondary unpaved roads, haulage roads, access roads and roads in developing areas. In most cases, geotextiles are placed between soft, fine-grained subgrade soils with sand or stone aggregates on top. Beginning in the 1970s, acceptance of this particular application led to a massive increase in the use of geotextiles. Based on field measurements of embankment stability (e.g., from California bearing ratio, shear strength, or modulus of elasticity tests, etc.), relatively simple calculations of the reduction in aggregate thickness required often indicate net cost savings from the use of geotextiles. Additionally, the separation feature of the non-woven PET filament geotextile prevents aggregate from mixing into the underlying subgrade, improving long-term performance.

Non-woven PET filament geotextile layer is one of the fastest growing sectors in the technical textiles market and is expected to maintain growth in the future. Synthetic fibers dominate the woven geotextiles market, but the use of natural fibers cannot be ignored, especially in developing countries. In addition, the standardization of certain properties and test methods will provide more reliable technical data and design methods for geotextiles. This will eventually lead to the design of geotextiles through the “design by function” route. As a result, the geotextile will more effectively perform its stated function over the life of the project. The combination of geotextile mechanics and soil mechanics can effectively solve countless construction and design problems.

Geotextiles are further divided into woven geotextiles and non-woven geotextiles. The former is woven from monofilaments or multi-strands, or woven from flat filaments cut into films; Formed into a mat, and then mechanically entangled or thermally bonded, or chemically bonded.

Non-woven PET filament geotextile layer can replace traditional engineering materials and construction methods, the construction is safer, and it contributes to environmental protection. It can solve basic problems in engineering construction more economically, effectively and permanently. Filament geotextiles have good Excellent mechanical function, good water permeability, anti-corrosion, anti-aging, has the functions of isolation, reverse filtration, drainage, protection, stabilization, reinforcement, etc. The non woven geotextile layer can adapt to uneven base, resist construction external force damage, small creep. The original function of the pavement can still be maintained under long-term load.

The non-woven PET filament geotextile is thicker, which can ensure the three-dimensional void ratio of the non-woven PET filament geotextile, which is conducive to the realization of excellent hydraulic performance; its bursting strength has great advantages, especially suitable for retaining walls and embankment reinforcement. The indicators of non-woven PET filament geotechnical pull force all exceed the standard, and it is an excellent geotechnical reinforcement material.
