Effects of Field-Wear Abrasion on Barrier Properties of Nonwoven Fabrics

Abstract

Eight nonwoven fabrics were made into experimental protective pants and worn into two types of low crop fields. Barrier properties (water penetration resistance, oil repellency, and air permeability) were measured for control fabrics and fabrics taken from pants worn in the field Results indicate that while loss of breaking strenth due to abrasion was minimal, effects of field wear on barrier properties were significant. Water penetration resistance and oil repellency were reduced and air permeability was increased for most specimens after wear in at least one of the fields. Fluorochemical finishes used on three of the fabrics were less effective after wear. The study suggests that performance of protective clothing may not be adequately assessed by testing fabrics prior to wear.
