1. Introduction of PP Woven Geotextile for Tunnel Engineering:

Geotextiles are composed from synthetic polypropylene/polyester fibres through a mechanical process of needling the fabric and adding, when necessary, a thermo fused process, resulting in a uniform porous structure with excellent tensile strength and chemical deterioration. Type: 1. Wovens & knitted: use various fibre types (e.g. monofilament, multi-filament, split extruded film) in different combinations. 2. Non-wovens: staple or continuous fibres that are heat treated or needlepunched to “fix” fibres relative to each other.
