Development of Experimental Cotton Dust Analyzer

ABSTRACT AN experimental cotton dust analyzer was developed for measurement of the dust-generation potential of lint cotton. High-velocity air jets are used in the analyzer for release of dust from a thin batt of lint. The dust is then sized by a 100-micrometer screen and collected on a glass fiber filter for gravimetric analysis. Laboratory results indicated that differences in dust-generation potential measured by the cotton dust analyzer were similar to those measured by experimental card room techniques. However, additional refinements and testing are needed for establishment of concrete relationships between results with the cotton dust analyzer and the potential of various types of cotton for dust generation.
