The Behaviour of Compacted Cotton Fibers in Hot Low Velocity Air Stream

Abstract

The degradation and morphology of compacted cotton fibers placed in hot oxidizing low velocity streams have been examined using a scanning electron microscope. The effects of sample compactness, stream velocity, stream tem perature and exposure time on the degradation of the cotton fibers were estab lished.

An Investigation of the Ignition and Combustion of Loosely Compacted Commercial Steel Wool

“…Effects of sample compactness, defined as the mass per unit of total volume, stream velocity, stream temperature and exposure time on the degradation of the cotton fibers when exposed to a steady heated low velocity stream of air were established. These findings were reported in earlier publications [1,2].…”

“…In both cases, the pressure rise within the fiber structure due to gas expansion caused by its exposure to high temperature, results in the expansion of the fiber shell, which ultimately forms the sphere. A comparison on the basis of fiber fineness was not possible within the scope of this work, as the study was restricted to one variety of cotton [1].…”
