Black nonwoven geotextile

Black nowoven geotextile has excellent filtration, isolation, reinforcement and protection, high tensile strength, good permeability, high temperature resistance, anti-freeze, aging resistance and corrosion resistance.

Black nonwoven geotextile are made of filaments or short fibers that are laid into a network through different equipment and processes. After a needle punching process, different fibers are intertwined with each other, and the fibers are entangled and fixed to make the fabrics soft and soft. Plump, thick, stiff, to meet different thicknesses to work  with black nonwoven geotextile is required that the non-woven geotextile has a good fabric gap and has good adhesion, because the fiber has a certain tear resistance and good deformation adaptability, and has good flat drainage ability and soft surface. The multi-gap has a good coefficient of friction to increase the adhesion of soil particles, etc. It can prevent fine particles from preventing the loss of particulate matter while eliminating excess water, and the surface is soft and has good protection ability. According to the length of the wire, it is divided into a filament Black nonwoven geotextile or a short-filament Black nonwoven geotextile. They all have good filtration, isolation, reinforcement, protection and other functions, and are a widely used geosynthetic material. The tensile strength of the filament is higher than that of the short filament, and can be selected according to specific requirements.

Black nonwoven geotextile is mainly made of high-quality polyester staple fiber (fiber 4-9dtex, length 50-76mm).Black nonwoven geotextile can also produce needle-punched non-woven geotextile of polypropylene, nylon, vinylon or mixed fiber according to requirements. Its applications could be uesd : 1. isolation from the layers; 2. filtration; 3. drainage the waterflow; 4. reinforcement the basement; 5. protection the road or the basement; 

Because the black nonwoven geotextile has the above many functions, it can be widely used in railways, highways, sports venues, dams, hydraulic structures, tunnels, beaches, cofferdams, environmental protection and other projects.
