 About nonwoven geotextiles
- Geotextile: Geotextiles are textile structures such as fabrics, mesh materials, nonwovens, nets, and composites, which are deployed in various areas of underground construction for separation, support, protection, filter and/or drainage functions.
- For nonwoven geotextiles, needle punch technology is in the forefront, and now it is most widely used.
- Principles of needle punch technology:
Needle punching is a technology to produce a fabric in which fibers are mechanically entangled by reciprocating barbed needles through a moving batt of fibres in a needle loom. The feed system introduces the batt between the lower bed plate and the upper striper plate by nip rollers or aprons, whilst a nip roller system draws the consolidated web away from the needling zone.
Difference between woven & nonwoven geotextiles:
