Abstract

An account is given of a determination of the influence that oxygen has on the persistence of burning of single- and multi-layered cotton samples as a function of igniter-application time at temperatures of 20 and 100°C. For a given environmental and ignition condition, burning times of each fabric sample linearly increase with oxygen concentration. Extrapolation enables the oxygen concentration at which the burning time is zero to be determined; this quantity is the extinction oxygen index or EOI. Each fabric at each temperature has an EOI value that decreases linearly as the igniter-application time increases, and thus extrapolation to zero time enables the index [EOI]o to be determined. Values of [EOI]o at each temperature linearly increase with the fabric area density and decrease curvilinearly with the logarithm of the air-permeability. Increasing the temperature has little effect on the slopes of these relationships but reduces the fabric-structure-independent component of [EOI]o or intrinsic extinction oxygen index from 0.135 at 20°C to 0.109 at 100°C.
