Four different levels of lint cleaning in the gin were applied to smooth-leaf and hairy-leaf cottons. Nine different mill cleaning sequences were applied to each level of gin cleaning, resulting in a total of thirty-six different combinations of gin/mill cleanings for each variety. This study suggests lint cleaners should be used only as a step in the cleaning process, and most cleaning should be done in the mill. Such a shift from conventional processing could significantly improve the quality of cotton and reduce the short fiber content. Mills would benefit by having better quality yarns and higher processing efficiency, especially in spinning.
