Accomplishments
1. Air-bar lint cleaner. Saw-type lint cleaners are now the most common lint cleaners used at gins because of their higher cleaning efficiency. Saw-type lint cleaning improves the grade of the fiber and increases the market value. However, during the cleaning process the saw-type lint cleaners damaged fiber in creating short fibers and neps. ARS scientists at Stoneville, Mississippi, developed an air-bar device and implemented it in a lint cleaner and tested it by comparing it to the conventional grid-bar lint cleaner. Samples of cotton lint processed with air-bar and conventional grid-bar were collected. HVI and AFIS properties of the samples including fiber length, strength, short fiber content, and trash content were tested. Results indicate that use of air-bar could significantly reduce the fiber content in motes and increase the ginning turnout.
