Low Speed Air-Flow Characterization of Military Fabrics

Abstract

Low speed air-flow studies have been conducted in order to characterize military cloth. Measurements were performed on the military cloth nylon/cotton (NYCO); in addition, cloth samples with specified pore size, open area and thickness were examined in order to develop criteria to characterize NYCO as well as other military fabrics. Data of air velocity through a cloth and corresponding pressure drop across the cloth were successfully modeled in two ways. The first was by application of a model based on air-flow through a single pore or orifice to the problem of air-flow through cloth samples which contain many pores. The second was by applying a model developed for air-flow through wire meshes or screens to air-flow through cloth. Keywords: Fabrics, Membranes, Air-flow, Polyester, Porosity, Fabric structure, Air permeability, Military cloth, Nylon, Cotton, Models, Protective clothing.
