Needle-punched non woven geotextile is formed by long yarn or short fiber laid to net sharp by different equipments and technology, different fibers interwining with each other through needle punching etc technics, this would make the fabrics normalized, soft, plump, thick and stiff to meet different thickness and usage requirements. Needle-punched non woven geotextile has good fabric gap and adhesion, meanwhile it has excellent adaptive ability to deformation and plane drainage capacity because of the fiber is soft and has a certain degree of anti-breaking ability.
