Classification of Geotextiles
Geotextile, also known as geotextile, is a water-permeable geosynthetic material made of synthetic fibers by needling or weaving. The finished product is cloth-like, generally 4-6 meters wide and 50-100 meters long. Geotextiles are divided into woven geotextiles and nonwoven geotextiles. Wholesale polyester nonwoven geotextile has excellent filtering, isolation, reinforcement and protection, high tensile strength, good permeability, high-temperature resistance, freeze resistance, aging resistance, and corrosion resistance.
1. Non-woven geotextile
Non-woven geotextiles are laid into a net shape by filaments or short fibers through different equipment and processes, and different fibers are intertwined with each other through needle punching and other processes. They are entangled and fixed to standardize the fabric and make the fabric soft, Full, thick, and stiff, to meet different requirements to meet the requirements of use, non-woven geotextiles have good fabric clearance, good adhesion, because the fiber is soft, has a certain resistance to tearing, and has good deformation adaptability Ability, while having a good plane drainage ability, the surface is soft and the gap has a good friction coefficient can increase the adhesion of soil particles, etc., can prevent fine particles by preventing the loss of particulate matter while eliminating excess water, the surface is soft and very soft Good protection. According to the length of the filament, it can be divided into filament non-woven geotextile or short filament nonwoven geotextile factory price. They can all play a good role in filtering, isolation, reinforcement, protection, etc., and are a widely used geosynthetic material. The tensile strength of filament is higher than that of staple, and it can be selected and used according to specific requirements.
2. Woven geotextile (reinforced geotextile)
Woven geotextiles are composed of at least two sets of parallel yarns (or flat yarns), one set is called warp yarn along the longitudinal direction of the loom (the direction of fabric travel), and the other set is called weft yarn. Different warp and weft yarns are interwoven with different weaving equipment and processes to weave into a cloth shape, which can be woven into different thicknesses and densities according to different use ranges. Generally, thinner geotextiles have a relatively strong resistance Tensile strength (longitude is greater than latitude), with very stable performance. Woven geotextiles are divided into reinforced geotextiles and unreinforced geotextiles according to the weaving process and the use of warp and weft. The tensile strength of reinforced geotextiles is much greater than that of ordinary geotextiles. Woven geotextiles are generally used in practice and reinforced and reinforced in geotechnical projects. The main function is reinforcement and reinforcement. They have plane isolation and protection functions. They do not have plane drainage functions and can be selected according to specific purposes.
3. Warp-knitted composite geotextile
The warp-knitted composite geotextile is a new type of geotechnical material made of glass fiber (or synthetic fiber) as a reinforcing material and compounded with staple fiber non-woven fabric.
Warp-knitted composite geotextiles are different from general woven fabrics. The biggest feature is that the intersections of the warp and weft are not curved, and they are in a flat state. Tie the two together firmly with a binding line, which can be synchronized more comprehensively and uniformly, withstand external forces and distribute stress, and when the external force is applied to tear the material, the yarn will gather along the initial crack, increasing the tear resistance.
When the warp knitting is compounded, the warp knitting wire is used to repeatedly pass between the warp, weft and staple fiber filament nonwoven geotextile for sale fiber layers, so that the three are knitted into one. Therefore, warp-knitted composite geotextiles not only have the characteristics of high tensile strength and low elongation, but also the properties of needle-punched nonwovens. Therefore, the warp-knitted composite geotextile can be used for reinforcement, isolation, and protection, and has a good three-dimensional overall normal and horizontal level of water and water. Because its solid matrix and pores are in a continuous phase, it has a multi-pore filtering effect and is a multifunctional geotechnical composite material. It is a high-level applied geotechnical composite substrate in the world.
