What is geotextile | JINHAOCHENG

Geotextile definition

Geotextile is made of high-strength fiber tow and non-woven fabric. The process is that the fiber bundles are arranged in a straight line, and the force of the yarn is fully exerted.

The non-woven mat is wound under the warp knitting technique, and the fiber tow non-woven fabric is fixed together, which not only maintains the anti-filtration of the non-woven fabric, but also has the strength of the woven fabric.

Geotextile fabric Characteristics

1. High strength, due to the use of plastic fiber, it can maintain sufficient strength and elongation in dry and wet conditions.

2, corrosion resistance, long-term corrosion resistance in soil and water of different pH.

3, good water permeability There are gaps between the fibers, so there is good water permeability.

4, good antimicrobial properties Microbes, insects are not damaged.

5. Convenient construction. Because the material is light and soft, it is convenient to transport, lay and construct.

6, complete specifications: the width can reach 9 meters. It is the widest product in China, with mass per unit area: 100-1000g/m*m

Geotextile types

1. Needle punched non woven geotextile:

Any choice between 100g/m2-600g/m2, the main raw material is made of polyester staple fiber or polypropylene staple fiber, which is made by needle punching;

The main purposes are: slope protection of rivers, seas and lakes, embankment, docks, ship locks, flood control, etc. It is an effective way to maintain soil and water and prevent flooding through back filtration.

2, Acupuncture non-woven fabric and PE film composite geotextile:

The specification has a cloth, a film, a second cloth and a film. The main material of the maximum width of 4.2 meters is to use a polyester staple fiber needle-punched nonwoven fabric, and the PE film is composited;

The main purpose is anti-seepage, suitable for railways, highways, tunnels, subways, airports and other projects.
