What is geotextile and its application?

What is non woven needle punch?

Nonwoven needle punch is a combination of a needling and a thermal bonding process of polypropylene fibers. Being polypropylene, the fibres used in the production of the nonwoven product range are extremely durable and exhibit excellent chemical resistance to acids and alkalis at ambient temperatures, have an exceptionally low moisture absorption such that the action of water at ambient temperature has no effect on their mechanical properties and are resistant to microorganisms and insects and will not support the growth of mildew or fungi.

The nonwoven range of the staple fiber needle punched and thermally bonded nonwoven textiles have been designed to offer optimum performance per unit weight. Their resulting mechanical robustness and excellent hydraulic properties make them the ideal choice for separation and filtration.
