Methods for Reducing Exposure to Cotton Dust

摘要

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.
