This article takes you on an in-depth study of the characteristics and advantages of non-woven geotextiles, and you will find that they have a significant impact on improving the performance and lifespan of various engineering solutions.

1. What is Non Woven geotextile? What Is the Production Process?

Non Woven Geotextile is a non-woven fabric material specifically used for civil engineering and environmental protection, with unique structure and performance. Its main functions are filtration, isolation, reinforcement, and drainage.

Production Process

1.1 Raw material preparation

Non woven geotextiles usually use synthetic fibers such as polypropylene and polyester as raw materials, which meet environmental protection requirements.

1.2 Fiber Formation

Fibers are made by melt spraying or other methods. The melt spraying method heats the polymer to a molten state and sprays it out through a nozzle to form fine fibers.

1.3 Establishing a network

Fibers are formed into a network through methods such as air flow networking, wet networking, or dry networking to ensure good interweaving between fibers.

1.4 Adhesive treatment

Fiber webs are bonded together using methods such as hot pressing, chemical bonding, or mechanical compaction to enhance the strength and stability of the material.

1.5 Post processing

Perform subsequent treatments such as UV resistance, antibacterial treatment, or staining to meet specific functional requirements.

This production process enables non-woven geotextiles to have excellent permeability, tear resistance, and durability, effectively isolating soil, rocks, and water bodies, and improving the stability and safety of engineering.
