Needlepunch Production for Geotextile Fabrics
topic
Geotextile needlepunch production processes polypropylene and polyester staple fibres at 80 to 2000 grams per square metre through carding, cross-lapping, and intensive needling to produce nonwoven geotextiles for separation, filtration, drainage, and protection applications in civil engineering, with UV stabiliser content and needle density governing the mechanical performance and service life of the geotextile in outdoor soil contact applications.
Role
Produces the highest volume technical needlepunch nonwoven application globally for civil engineering geotextiles where the three-dimensional fibre entanglement provides the combination of conformability to irregular ground surfaces, controlled hydraulic conductivity for drainage and filtration, and tensile strength for soil reinforcement that makes needlepunched polypropylene the dominant material for road construction and drainage geotextile applications.
