Non Woven Geotextiles Have Geotextiles And Warp Knitted Composite Geotextiles.

Nonwoven geotextiles

It is arranged in a mesh, and through needling and other processes, different fibers are intertwined, intertwined and fixed, so that the fabric is standardized, so that the fabric is soft, plump, thick and stiff, so that different thickness can meet the requirements of making use. The non-woven geotextiles have good fabric clearance and good attachment. Because the fiber is soft, it has certain tear resistance, which has good adaptability to deformation and adaptability, and has good plane drainage ability. The surface is soft, and many gaps have a good friction coefficient to increase the adhesion ability of soil particles. It can prevent small particles from blocking the loss of particles and eliminating excess moisture. The surface is soft and has good protection ability. It is made of filament or staple through different equipment and technology.

According to the length of the filament, it can be divided into filament nonwoven geotextiles or short filament nonwoven geotextiles.

They can play a good role in filtration, isolation, reinforcement, protection, and so on. They are widely used geosynthetics.

The tensile strength of filaments is higher than that of short wires, which can be selected according to specific requirements.

There are geotextiles.

(reinforced geotextiles)

A geotextile is made up of at least two sets of parallel yarns (or flat yarns). A group of yarns is called longitudinal yarns along the longitudinal direction of the looms, and the other is a pverse arrangement called weft yarn.

Weaving weft yarns and weft yarns with different knitting machines and weaves can be woven into cloth. They can be woven into different thickness and density according to different application ranges. Generally speaking, Geotextiles have relatively strong tensile strength (longitude over latitude) and have good stability.

According to the weaving process and the warp and weft difference, geotextiles are divided into two categories: reinforced geotextiles and non reinforced geotextiles. The tensile strength of reinforced geotextiles is much larger than that of geotextiles.

There are geotextiles in general practical applications and geotechnical engineering projects reinforced reinforcement, the main function is reinforced reinforcement, with plane isolation and protection function, do not have flat drainage function can be selected for specific purposes.

Warp knitted composite geotextiles

It is a new type of geomembrane made of glass fiber (or synthetic fiber) and reinforced with short fiber needled nonwoven fabric.

Warp knitted composite geotextiles are different from ordinary woven fabrics.

Its main feature is that the intersection point between the warp and the weft is not curved, and each of them is in a straight state.

Using bundled wires to bind them firmly, it can be more evenly and synchronously, bear external force and distribute stress. When the external force is tearing material, the yarn will gather along the initial crack and increase the tear strength.

When warp knitted is used, the warp knitted binding line is used to weft through the fiber layer between the weft yarn and the short fiber needle geotextile, so that the three can be knitted together.

Therefore, warp knitted composite geotextiles have the characteristics of high tensile strength, low elongation and needle punched nonwovens.

Therefore, warp knitted composite geotextiles can be used for reinforcement, isolation and protection, and have the function of gathering water and water differently.

Because its solid matrix and pores are continuous and porous, it is a multifunctional geosynthetics.

It is the international high level geosynthetics substrate.
