In-Plane Liquid Distribution in Nonwoven Fabrics: Part 2 — Simulation

Abstract

In a recent paper, we reported on a new absorbency testing system that measures in-plane fluid flow, absorbency and pore volume distribution [8]. The importance of fiber orientation characteristic in nonwovens, as it directly influences the in-plane fluid flow in nonwovens was explored.In this paper, we present a framework for the prediction of in-plane wicking in nonwovens. This paper describes the underlying foundation for the simulation of in-plane wicking and reports on preliminary comparisons between simulation and experimental data.
