Abstract
The effectiveness of additives and the blending of fibers on dust emission during carding, the relationship between dust particle size and grade of cotton, and amount of oil mist in dust from treated cottons were investigated. Six additives were evaluated for dust suppressant abilities on high micronaire cotton. A substantial reduction in dust generated was achieved by the addition of very small amounts of five of the additives. For polyester and cotton blends, the dust generated increased as the cotton content of the blend increased and as the production rate increased. Specific studies conducted revolved around the effect of washing cotton after ginning to cut down on dust generation, the effectiveness of the Cottonmaster as a mechanical cleaning device, the effect of harvesting cotton with different types of mechanical pickers on the dust produced, the operating characteristics of the SRRC Precutter Sampler and its equivalence to the Vertical Elutriator Cotton Dust Sampler, the effect of genetic variations on dust generation, the processing of cottons varying in gram negative bacteria content, dust suppressing additives and their ability to suppress dust release, the effectiveness of Smog-Hog air cleaner for dust removal, harvesting and genetic variations, measurement of particle size distribution, the presence of microorganisms, and the possibility that humidifiers serve as a source of respirable dust.
