Controlled-batt saw-type lint cleaners remove undesirable contaminants from the fiber such as leaf particles, motes, grass, bark, and seed coat fragments. Newly-designed grid bars may be effective in removing some of the contaminants, especially seed coat fragments. A lint cleaner simulator was developed to imitate the action of a lint cleaner whipping fiber, with a seed coat fragment attached to it, across a grid bar. High-speed digital video was used to photograph the whipping action. The simulator and video enables researchers to evaluate numerous small-scale experimental grid bars before testing them on full-size lint cleaners.
