Effect of fibre orientation on mechanical and functional properties of needle-punched nonwoven

Abstract

An attempt has been made to study the effect of fibre orientation, measured by the structural characteristics, onmechanical and functional properties of needle-punched nonwoven by varying the carding machine and punchingparameters. It is observed that all measured physical, mechanical and functional properties of nonwovens have strongcorrelation with the proposed structural characteristics. Cylinder speed, punch density and needle depth penetration havesignificant effect on fabric thickness, air permeability, pore diameter, filtration efficiency and pressure drop.
