Spinning Quality of Cotton as Affected by Gin Cleaning, Card Crusher Rolls, and Varying Carding Rates, Mississippi, 1965-66 Season

Excerpts from the report: The presence of foreign matter in cotton presents difficulties in manufacturing, and affects both producers ' returns and manufacturers' costs. The presence of trash in cotton and the methods used to remove trash to a great extent determine the processability and end-use value of cotton. Studies have identified many of the difficulties associated with trash removal and have, to some extent, indicated the kinds of actions required to clean cotton while preserving its inherent, desirable qualities. This study continues and extends previous work concerning effects of gin cleaning and use of crusher rolls on cotton quality and begins an investigation of the effects of different rates of carding. The purpose of the total program is to obtain data needed to improve marketing of cotton. Specifically, the objectives of this study were (1) to determine the effects on the processing performance of cotton, of variations in seed cotton and lint cleaning at the gin, and of use of card crusher rolls at various carding rates, and (2) to study the relationships among these effects, the costs of processing, and the present marketing system.
