Spunbonded Nonwoven Geotextiles

    Description

    Spunbonded nonwoven geotextiles typically have more uniform properties than other structures of nonwoven. They are produced using medium to coarse dpf continous filament fibers.

    Description of Spunbonded Nonwoven Geotextiles

    It is similar to filament yarn production. From the chips storage, the polymer is vacuum-fed to a dosing station on top of the extruder. Inside the extruder, it becomes melted and homogenized. Passing a filter system and a spin pump, the melt is fed into the spin beam or spinnerets, which form a curtain of filaments. The filaments are cooled by means of a stream of air in a blowing area, drawn by aerodynamic forces and then transported to the downstream discharge channel. For nonwovens, instead of a further stretching process for filament yarns, the filaments are swirled around and then deposited on the wire mesh belt as a random nonwoven. This web is transferred to a bonding calender that uses heat and pressure to set such physical properties as tensile strength and elongation of the final product. After cooling, the material can be wound.
