Technical Abstract: New technology to automatically engage/disengage grid bars in saw-type lint cleaners to reduce fiber waste and associated fiber damage was evaluated in four studies. The number of active grid bars in the studies varied from 0 to 10, and as grid bars increased, fiber loss and damage increased. Typically for a single 5-grid bar lint cleaner, about 50% of the material was removed by the first two grid bars; for two lint cleaners, about 40% o the material was removed by the first two grid bars. Short fiber content and neps increased over 30% as grid bars increased from 2 to 10, and mill performance was degraded. Material removed from lint by saw-type lint cleaners is strongly related to variety, growing conditions and harvesting, and ranged from 6.1 to 17.5 kg (13.4 to 38.6 pounds) per bale when two lint cleaners were used. In a 39,000 bale field study where lint cleaning was optimized by a computerized process control system, fiber loss from two grid bars (3.6 kg or 8 pounds per bale) was about 25% of that from five grid bars (13.6 kg or 30 pounds per bale).
