Removing Seed Coat Fragments with Newly-Designed Lint Cleaner Grid Bars

Controlled-batt saw-type lint cleaners use grid bars to remove foreign material from cotton fiber such as leaf particles, motes, grass, bark, and seed coat fragments.  An experiment was run to evaluate the effectiveness of newly-designed grid bars in removing seed coat fragments.  The grid bars were tested on a full-size conventional lint cleaner.  The grid bars consisted of four experimental designs and a control.  Two cotton cultivars were used.  One of the cultivars was prone to having a fragile seed coat.  Results to be reported include fiber properties and foreign content matter on the fiber and lint cleaner trash.
