The effect of cotton grade, variety and growing location on dust generated in a model card room was studied. Cotton included in this analysis was grown in 13 states consisting of 10 varieties and 5 grades. Data was evaluated by determining whether any deviations in the amount of dust emitted by individual bales from that of the average measured on all bales of the same grade of cotton could be attributed to growing location or variety. A total of 140 bales were processed in 305 runs; two bales of each item were processed and examined on 2 consecutive days. Cotton grown in the Eastern United States produced less dust in the card room, and cotton grown in the arid areas of the West produced more dust than the average. Factors affecting the amount of dust emitted included harvesting time, steaming of cotton and growing of the same variety of cotton in the same field 2 years in succession. The authors conclude that several uncontrollable and overriding factors obscured the attempt at determining whether cotton grade, growing location and genetic variety affect the levels of dust emitted during the processing of cotton.
