Abstract
Several studies of cotton dust control technology were undertaken and their results were reviewed. The effect of including lint cleaners in the ginning line has been shown to be effective in reducing dust emission during carding. Normally only two cleaners were employed, as they do produce some fiber damage and loss. A study of the influence of feeder/cleaners to remove 50 to 60 percent of the large trash such as sticks and burr from seed cotton before it enters the gin suggested possible increases in cotton dust generated from this process. The process of steaming cotton in the bale before processing reduced the amount of respirable dust emitted during carding. When cotton was warehoused after steaming and before processing, the dust levels emitted were higher than when the cotton was processed immediately after steaming. The effect of leaving the cotton dust lint cake deposited on the filters for longer than a 1 day work period produced lower levels of airborne dusts. The effectiveness of the Cottonmaster, a cleaning device, was evaluated on two grades of cotton. Results indicated that dust emission during carding was lower for the cotton passed through the Cottonmaster. Washing cotton prior to processing decreased the dust emission in carding. Such treatment also greatly reduced the rate at which the cotton could be carded. Several commercial and experimental formulations were used as additives to control dust formation. Some of these proved helpful in reducing dust levels generated during carding. The usefulness of electrostatic precipitator devices was also examined.
