Saw-cylinder lint cleaners are used at cotton gins to blend the fibers, remove foreign-matter from lint, improve the classer's grade, and increase the market value of the bale. A saw-cylinder lint cleaner was modified to include carding action by removing the first grid bar and replacing it with a commercially available card brush. This treatment was compared to a control to determine its effect on gin turnout, lint-cleaner efficiency, and fiber quality. The experimental treatment operated at a feed rate of one bale per hour per foot of lint cleaner saw-cylinder length. The gin treatment differences are attributed to the combination of the absence of the first grid bar and the use of the first bar and the use of the card brush on the saw cylinder.
