Introduction

Non-woven geotextiles are engineered fabrics widely utilized in civil engineering projects. These materials are designed to provide separation, filtration, protection, drainage, and reinforcement in various geotechnical applications. Manufactured from synthetic fibers via mechanical, chemical, or thermal bonding processes, non-woven geotextiles boast distinct properties that make them suitable for multiple uses.

Applications of Non-Woven Geotextiles

Non-woven geotextiles play a crucial role in a broad array of applications, including:

1. Separation: These geotextiles prevent the mixing of dissimilar materials, such as different soil layers, thus maintaining the integrity of each layer.
2. Filtration: Non-woven geotextiles allow fluid flow across the plane while retaining fine particles, crucial in applications like drainage systems.
3. Protection: They provide a cushioning effect, protecting geomembranes in landfill liners from punctures.
4. Drainage: Facilitating fluid movement along the fabric, these geotextiles serve as efficient drainage channels.
5. Reinforcement: Enhancing soil strength, they improve load distribution in road construction and other infrastructures.

4. TX-TEX 700: A multipurpose geotextile that integrates all core functionalities, ideal for complex projects.

Numerical Analysis of Non-Woven Geotextiles

Non-woven geotextiles are evaluated based on several key parameters:

1. Permeability: A critical factor for filtration and drainage applications, values range from 0.1 to 0.5 cm/s.
2. Tensile Strength: Ranging from 10 kN/m to 30 kN/m, this property is essential for reinforcement applications.
3. Puncture Resistance: Ensures durability under stress, with values commonly ranging from 1000 N to 2500 N.
4. Weight: Typically measured in grams per square meter (gsm), non-woven geotextiles range from 100 gsm to 600 gsm.
