NON-WOVEN GEOTEXTILE

Nonwoven geotextiles are produced with regular filament yarn or short-staple fiber. The fibers are joined by chemical, thermal-mechanical, mechanical, or any combination of these techniques. The thickness of ground fibers created through mechanical interlocking and thermal bonding ranges from 0.5-1 millimeter. The chemically-bonded nonwoven is approximately around 3 millimeters.
It is a new technology in high-tech processes in which filaments or synthetic polymer fibers are extruded continuously and laid in moving conveyor belts. The mass of fibers or filaments are needle punched where filaments are mechanically bound through a set of tiny needles that allow fibers to be connected by heat or pressure at the point of contact within an unwoven mass.
