Manufacturing Technique and Property Evaluation of Polyester/Polypropylene Fasciated Yarn Used in Geogrids

Abstract:

The successive civilengineering disasters in recent years make the use of geomaterial for disaster prevention popular. Geogrids, one type of geo-material, function as soil reinforcement. This study uses polypropylene (PP) fibers to wrap high strength polyester (HSPET) fibers, forming the PP/HSPET fasciated yarn. PP fibers are acid-resistant and alkali-resistant, and thus serve as the skin of the fasciated yarn. HSPET fibers, the core of the fasciated yarn, protect and prolong the service life of the resulting geo-material products. Finally, the influence of mechanical parameters on the appearance and strength of the fascinated yarn is explored.
