Long Fiber PET Geotextile

PET Needle Punched Nonwoven Geotextile is a needle punched nonwoven geotextile polyester paving geotextile that provides stress relief, waterproofing, and reflective cracking capabilities in new and existing pavements.

Needle punched non-woven geotextile fabric is a permeable fabric used for rocks, soils and other geotechnical materials. Made of non-woven material.

A permeable material is one that allows gases or liquids to pass through it.

Needle-punched nonwoven geotextile fabrics are typically manufactured using needle-punched or thermal bonding processes. Needle-punched nonwoven geotextiles are made using materials such as polyester, polypropylene, and polyamide.

Jute, coil, sisal, and other natural fibers are also used to make some nonwoven geotextiles. Jute-based geotextiles are completely biodegradable. This is usually used for seed germination and is called a 'jute seed pad'.

However, the majority of needle-punched nonwoven geotextiles are made from polypropylene fibers due to their high strength, low price, and low specific gravity.

When a machine drives a large number of needles directly onto the web, it is known as needle punching. The web becomes flexible and, as a result, pores develop. These pores allow for optimal drainage and filtration while increasing the fabric's breathability.

Non-woven geotextiles have a wide range of applications in civil and environmental engineering and construction projects.

Filtration

Non-woven geotextiles can retain fine particles well as water moves from the fine-grained layer to the coarse-grained layer. For example, water flows from sandy soil into a gravel drainage channel wrapped in geotextile.

Separation

Separating two layers of soil with different physical properties, such as separating road gravel and soft subgrade materials.

Drainage

To evacuate liquids or gases from fabric surfaces. leading to drainage or aeration of the soil, such as a gas venting layer in a landfill cap.

Reinforcement

Improving the load capacity of certain earth structures, such as reinforcing retaining walls.

1. Polyester Nonwoven Geotextile has good air and water permeability to let water flow through it so as to effectively control sandrock running-down.
2. Geotextile has good water transmissibility, it can form drainage channels inside soil mass to drain redundant liquid and air out of the soil mass.
3. Geotextile helps to enhance the soil mass' tensile strength and non-deformability and structural stability so as to improve soil mass quality.
4. It can effectively make the concentrated stress diffuse, transfer or decompound, and prevent the soil mass against the destruction of outside force.
5. It can prevent the mixture of sandstone, soil mass and concrete of upper and lower layers.
6. Its mesh is hard to jam by virtue of the compliancy and motility of the reticulation formed by indefinite form fibrous tissue.
7. High water permeability-it can keep good water permeability even in the pressure of soil and water.
8. Corrosion resistant-it is made from polypropylene fiber or terylene or other chemical fiber, featuring resistance to acid and alkali and oxidation, non-corroding, no worm-eaten.
9. Easy construction-low weight, easy operation, simple construction.
